- <title>Introduction</title>
- <para>
- The syncppp drivers in Linux provide a fairly complete
- implementation of Cisco HDLC and a minimal implementation of
- PPP. The longer term goal is to switch the PPP layer to the
- generic PPP interface that is new in Linux 2.3.x. The API should
- remain unchanged when this is done, but support will then be
- available for IPX, compression and other PPP features

+Using special makers (called 'nulls') is a convenient way
+to solve following problem :
+
+A typical RCU linked list managing objects which are
+allocated with SLAB_DESTROY_BY_RCU kmem_cache can
+use following algos :
+
+1) Lookup algo
+--------------
+rcu_read_lock()
+begin:
+obj = lockless_lookup(key);
+if (obj) {
+ if (!try_get_ref(obj)) // might fail for free objects
+ goto begin;
+ /*
+ * Because a writer could delete object, and a writer could
+ * reuse these object before the RCU grace period, we
+ * must check key after geting the reference on object
+ */
+ if (obj->key != key) { // not the object we expected
+ put_ref(obj);
+ goto begin;
+ }
+}
+rcu_read_unlock();
+
+Beware that lockless_lookup(key) cannot use traditional hlist_for_each_entry_rcu()
+but a version with an additional memory barrier (smp_rmb())
+
+lockless_lookup(key)
+{
+ struct hlist_node *node, *next;
+ for (pos = rcu_dereference((head)->first);
+ pos && ({ next = pos->next; smp_rmb(); prefetch(next); 1; }) &&
+ ({ tpos = hlist_entry(pos, typeof(*tpos), member); 1; });
+ pos = rcu_dereference(next))
+ if (obj->key == key)
+ return obj;
+ return NULL;
+
+And note the traditional hlist_for_each_entry_rcu() misses this smp_rmb() :
+
+ struct hlist_node *node;
+ for (pos = rcu_dereference((head)->first);
+ pos && ({ prefetch(pos->next); 1; }) &&
+ ({ tpos = hlist_entry(pos, typeof(*tpos), member); 1; });
+ pos = rcu_dereference(pos->next))
+ if (obj->key == key)
+ return obj;
+ return NULL;
+}
+
+Quoting Corey Minyard :
+
+"If the object is moved from one list to another list in-between the
+ time the hash is calculated and the next field is accessed, and the
+ object has moved to the end of a new list, the traversal will not
+ complete properly on the list it should have, since the object will
+ be on the end of the new list and there's not a way to tell it's on a
+ new list and restart the list traversal. I think that this can be
+ solved by pre-fetching the "next" field (with proper barriers) before
+ checking the key."
+
+2) Insert algo :
+----------------
+
+We need to make sure a reader cannot read the new 'obj->obj_next' value
+and previous value of 'obj->key'. Or else, an item could be deleted
+from a chain, and inserted into another chain. If new chain was empty
+before the move, 'next' pointer is NULL, and lockless reader can
+not detect it missed following items in original chain.
+
+/*
+ * Please note that new inserts are done at the head of list,
+ * not in the middle or end.
+ */
+obj = kmem_cache_alloc(...);
+lock_chain(); // typically a spin_lock()
+obj->key = key;
+atomic_inc(&obj->refcnt);
+/*
+ * we need to make sure obj->key is updated before obj->next
+ */
+smp_wmb();
+hlist_add_head_rcu(&obj->obj_node, list);
+unlock_chain(); // typically a spin_unlock()
+
+
+3) Remove algo
+--------------
+Nothing special here, we can use a standard RCU hlist deletion.
+But thanks to SLAB_DESTROY_BY_RCU, beware a deleted object can be reused
+very very fast (before the end of RCU grace period)
+
+if (put_last_reference_on(obj) {
+ lock_chain(); // typically a spin_lock()
+ hlist_del_init_rcu(&obj->obj_node);
+ unlock_chain(); // typically a spin_unlock()
+ kmem_cache_free(cachep, obj);
+}
+
+
+
+--------------------------------------------------------------------------
+With hlist_nulls we can avoid extra smp_rmb() in lockless_lookup()
+and extra smp_wmb() in insert function.
+
+For example, if we choose to store the slot number as the 'nulls'
+end-of-list marker for each slot of the hash table, we can detect
+a race (some writer did a delete and/or a move of an object
+to another chain) checking the final 'nulls' value if
+the lookup met the end of chain. If final 'nulls' value
+is not the slot number, then we must restart the lookup at
+the begining. If the object was moved to same chain,
+then the reader doesnt care : It might eventually
+scan the list again without harm.
+
+
+1) lookup algo
+
+ head = &table[slot];
+ rcu_read_lock();
+begin:
+ hlist_nulls_for_each_entry_rcu(obj, node, head, member) {
+ if (obj->key == key) {
+ if (!try_get_ref(obj)) // might fail for free objects
+ goto begin;
+ if (obj->key != key) { // not the object we expected
+ put_ref(obj);
+ goto begin;
+ }
+ goto out;
+ }
+/*
+ * if the nulls value we got at the end of this lookup is
+ * not the expected one, we must restart lookup.
+ * We probably met an item that was moved to another chain.
+ */
+ if (get_nulls_value(node) != slot)
+ goto begin;
+ obj = NULL;
+
+out:
+ rcu_read_unlock();
+
+2) Insert function :
+--------------------
+
+/*
+ * Please note that new inserts are done at the head of list,
+ * not in the middle or end.
+ */
+obj = kmem_cache_alloc(cachep);
+lock_chain(); // typically a spin_lock()
+obj->key = key;
+atomic_set(&obj->refcnt, 1);
+/*
+ * insert obj in RCU way (readers might be traversing chain)
+ */
+hlist_nulls_add_head_rcu(&obj->obj_node, list);
+unlock_chain(); // typically a spin_unlock()

+CONFIG_RCU_TRACE debugfs Files and Formats
+
+
+The rcupreempt and rcutree implementations of RCU provide debugfs trace
+output that summarizes counters and state. This information is useful for
+debugging RCU itself, and can sometimes also help to debug abuses of RCU.
+Note that the rcuclassic implementation of RCU does not provide debugfs
+trace output.
+
+The following sections describe the debugfs files and formats for
+preemptable RCU (rcupreempt) and hierarchical RCU (rcutree).
+
+
+Preemptable RCU debugfs Files and Formats
+
+This implementation of RCU provides three debugfs files under the
+top-level directory RCU: rcu/rcuctrs (which displays the per-CPU
+counters used by preemptable RCU) rcu/rcugp (which displays grace-period
+counters), and rcu/rcustats (which internal counters for debugging RCU).
+
+The output of "cat rcu/rcuctrs" looks as follows:
+
+CPU last cur F M
+ 0 5 -5 0 0
+ 1 -1 0 0 0
+ 2 0 1 0 0
+ 3 0 1 0 0
+ 4 0 1 0 0
+ 5 0 1 0 0
+ 6 0 2 0 0
+ 7 0 -1 0 0
+ 8 0 1 0 0
+ggp = 26226, state = waitzero
+
+The per-CPU fields are as follows:
+
+o "CPU" gives the CPU number. Offline CPUs are not displayed.
+
+o "last" gives the value of the counter that is being decremented
+ for the current grace period phase. In the example above,
+ the counters sum to 4, indicating that there are still four
+ RCU read-side critical sections still running that started
+ before the last counter flip.
+
+o "cur" gives the value of the counter that is currently being
+ both incremented (by rcu_read_lock()) and decremented (by
+ rcu_read_unlock()). In the example above, the counters sum to
+ 1, indicating that there is only one RCU read-side critical section
+ still running that started after the last counter flip.
+
+o "F" indicates whether RCU is waiting for this CPU to acknowledge
+ a counter flip. In the above example, RCU is not waiting on any,
+ which is consistent with the state being "waitzero" rather than
+ "waitack".
+
+o "M" indicates whether RCU is waiting for this CPU to execute a
+ memory barrier. In the above example, RCU is not waiting on any,
+ which is consistent with the state being "waitzero" rather than
+ "waitmb".
+
+o "ggp" is the global grace-period counter.
+
+o "state" is the RCU state, which can be one of the following:
+
+ o "idle": there is no grace period in progress.
+
+ o "waitack": RCU just incremented the global grace-period
+ counter, which has the effect of reversing the roles of
+ the "last" and "cur" counters above, and is waiting for
+ all the CPUs to acknowledge the flip. Once the flip has
+ been acknowledged, CPUs will no longer be incrementing
+ what are now the "last" counters, so that their sum will
+ decrease monotonically down to zero.
+
+ o "waitzero": RCU is waiting for the sum of the "last" counters
+ to decrease to zero.
+
+ o "waitmb": RCU is waiting for each CPU to execute a memory
+ barrier, which ensures that instructions from a given CPU's
+ last RCU read-side critical section cannot be reordered
+ with instructions following the memory-barrier instruction.
+
+The output of "cat rcu/rcugp" looks as follows:
+
+oldggp=48870 newggp=48873
+
+Note that reading from this file provokes a synchronize_rcu(). The
+"oldggp" value is that of "ggp" from rcu/rcuctrs above, taken before
+executing the synchronize_rcu(), and the "newggp" value is also the
+"ggp" value, but taken after the synchronize_rcu() command returns.
+
+
+The output of "cat rcu/rcugp" looks as follows:
+
+na=1337955 nl=40 wa=1337915 wl=44 da=1337871 dl=0 dr=1337871 di=1337871
+1=50989 e1=6138 i1=49722 ie1=82 g1=49640 a1=315203 ae1=265563 a2=49640
+z1=1401244 ze1=1351605 z2=49639 m1=5661253 me1=5611614 m2=49639
+
+These are counters tracking internal preemptable-RCU events, however,
+some of them may be useful for debugging algorithms using RCU. In
+particular, the "nl", "wl", and "dl" values track the number of RCU
+callbacks in various states. The fields are as follows:
+
+o "na" is the total number of RCU callbacks that have been enqueued
+ since boot.
+
+o "nl" is the number of RCU callbacks waiting for the previous
+ grace period to end so that they can start waiting on the next
+ grace period.
+
+o "wa" is the total number of RCU callbacks that have started waiting
+ for a grace period since boot. "na" should be roughly equal to
+ "nl" plus "wa".
+
+o "wl" is the number of RCU callbacks currently waiting for their
+ grace period to end.
+
+o "da" is the total number of RCU callbacks whose grace periods
+ have completed since boot. "wa" should be roughly equal to
+ "wl" plus "da".
+
+o "dr" is the total number of RCU callbacks that have been removed
+ from the list of callbacks ready to invoke. "dr" should be roughly
+ equal to "da".
+
+o "di" is the total number of RCU callbacks that have been invoked
+ since boot. "di" should be roughly equal to "da", though some
+ early versions of preemptable RCU had a bug so that only the
+ last CPU's count of invocations was displayed, rather than the
+ sum of all CPU's counts.
+
+o "1" is the number of calls to rcu_try_flip(). This should be
+ roughly equal to the sum of "e1", "i1", "a1", "z1", and "m1"
+ described below. In other words, the number of times that
+ the state machine is visited should be equal to the sum of the
+ number of times that each state is visited plus the number of
+ times that the state-machine lock acquisition failed.
+
+o "e1" is the number of times that rcu_try_flip() was unable to
+ acquire the fliplock.
+
+o "i1" is the number of calls to rcu_try_flip_idle().
+
+o "ie1" is the number of times rcu_try_flip_idle() exited early
+ due to the calling CPU having no work for RCU.
+
+o "g1" is the number of times that rcu_try_flip_idle() decided
+ to start a new grace period. "i1" should be roughly equal to
+ "ie1" plus "g1".
+
+o "a1" is the number of calls to rcu_try_flip_waitack().
+
+o "ae1" is the number of times that rcu_try_flip_waitack() found
+ that at least one CPU had not yet acknowledge the new grace period
+ (AKA "counter flip").
+
+o "a2" is the number of time rcu_try_flip_waitack() found that
+ all CPUs had acknowledged. "a1" should be roughly equal to
+ "ae1" plus "a2". (This particular output was collected on
+ a 128-CPU machine, hence the smaller-than-usual fraction of
+ calls to rcu_try_flip_waitack() finding all CPUs having already
+ acknowledged.)
+
+o "z1" is the number of calls to rcu_try_flip_waitzero().
+
+o "ze1" is the number of times that rcu_try_flip_waitzero() found
+ that not all of the old RCU read-side critical sections had
+ completed.
+
+o "z2" is the number of times that rcu_try_flip_waitzero() finds
+ the sum of the counters equal to zero, in other words, that
+ all of the old RCU read-side critical sections had completed.
+ The value of "z1" should be roughly equal to "ze1" plus
+ "z2".
+
+o "m1" is the number of calls to rcu_try_flip_waitmb().
+
+o "me1" is the number of times that rcu_try_flip_waitmb() finds
+ that at least one CPU has not yet executed a memory barrier.
+
+o "m2" is the number of times that rcu_try_flip_waitmb() finds that
+ all CPUs have executed a memory barrier.
+
+
+Hierarchical RCU debugfs Files and Formats
+
+This implementation of RCU provides three debugfs files under the
+top-level directory RCU: rcu/rcudata (which displays fields in struct
+rcu_data), rcu/rcugp (which displays grace-period counters), and
+rcu/rcuhier (which displays the struct rcu_node hierarchy).
+
+The output of "cat rcu/rcudata" looks as follows:
+
+rcu:

+
+The first section lists the rcu_data structures for rcu, the second for
+rcu_bh. Each section has one line per CPU, or eight for this 8-CPU system.
+The fields are as follows:
+
+o The number at the beginning of each line is the CPU number.
+ CPUs numbers followed by an exclamation mark are offline,
+ but have been online at least once since boot. There will be
+ no output for CPUs that have never been online, which can be
+ a good thing in the surprisingly common case where NR_CPUS is
+ substantially larger than the number of actual CPUs.
+
+o "c" is the count of grace periods that this CPU believes have
+ completed. CPUs in dynticks idle mode may lag quite a ways
+ behind, for example, CPU 4 under "rcu" above, which has slept
+ through the past 25 RCU grace periods. It is not unusual to
+ see CPUs lagging by thousands of grace periods.
+
+o "g" is the count of grace periods that this CPU believes have
+ started. Again, CPUs in dynticks idle mode may lag behind.
+ If the "c" and "g" values are equal, this CPU has already
+ reported a quiescent state for the last RCU grace period that
+ it is aware of, otherwise, the CPU believes that it owes RCU a
+ quiescent state.
+
+o "pq" indicates that this CPU has passed through a quiescent state
+ for the current grace period. It is possible for "pq" to be
+ "1" and "c" different than "g", which indicates that although
+ the CPU has passed through a quiescent state, either (1) this
+ CPU has not yet reported that fact, (2) some other CPU has not
+ yet reported for this grace period, or (3) both.
+
+o "pqc" indicates which grace period the last-observed quiescent
+ state for this CPU corresponds to. This is important for handling
+ the race between CPU 0 reporting an extended dynticks-idle
+ quiescent state for CPU 1 and CPU 1 suddenly waking up and
+ reporting its own quiescent state. If CPU 1 was the last CPU
+ for the current grace period, then the CPU that loses this race
+ will attempt to incorrectly mark CPU 1 as having checked in for
+ the next grace period!
+
+o "qp" indicates that RCU still expects a quiescent state from
+ this CPU.
+
+o "rpfq" is the number of rcu_pending() calls on this CPU required
+ to induce this CPU to invoke force_quiescent_state().
+
+o "rp" is low-order four hex digits of the count of how many times
+ rcu_pending() has been invoked on this CPU.
+
+o "dt" is the current value of the dyntick counter that is incremented
+ when entering or leaving dynticks idle state, either by the
+ scheduler or by irq. The number after the "/" is the interrupt
+ nesting depth when in dyntick-idle state, or one greater than
+ the interrupt-nesting depth otherwise.
+
+ This field is displayed only for CONFIG_NO_HZ kernels.
+
+o "dn" is the current value of the dyntick counter that is incremented
+ when entering or leaving dynticks idle state via NMI. If both
+ the "dt" and "dn" values are even, then this CPU is in dynticks
+ idle mode and may be ignored by RCU. If either of these two
+ counters is odd, then RCU must be alert to the possibility of
+ an RCU read-side critical section running on this CPU.
+
+ This field is displayed only for CONFIG_NO_HZ kernels.
+
+o "df" is the number of times that some other CPU has forced a
+ quiescent state on behalf of this CPU due to this CPU being in
+ dynticks-idle state.
+
+ This field is displayed only for CONFIG_NO_HZ kernels.
+
+o "of" is the number of times that some other CPU has forced a
+ quiescent state on behalf of this CPU due to this CPU being
+ offline. In a perfect world, this might neve happen, but it
+ turns out that offlining and onlining a CPU can take several grace
+ periods, and so there is likely to be an extended period of time
+ when RCU believes that the CPU is online when it really is not.
+ Please note that erring in the other direction (RCU believing a
+ CPU is offline when it is really alive and kicking) is a fatal
+ error, so it makes sense to err conservatively.
+
+o "ri" is the number of times that RCU has seen fit to send a
+ reschedule IPI to this CPU in order to get it to report a
+ quiescent state.
+
+o "ql" is the number of RCU callbacks currently residing on
+ this CPU. This is the total number of callbacks, regardless
+ of what state they are in (new, waiting for grace period to
+ start, waiting for grace period to end, ready to invoke).
+
+o "b" is the batch limit for this CPU. If more than this number
+ of RCU callbacks is ready to invoke, then the remainder will
+ be deferred.
+
+
+The output of "cat rcu/rcugp" looks as follows:
+
+rcu: completed=33062 gpnum=33063
+rcu_bh: completed=464 gpnum=464
+
+Again, this output is for both "rcu" and "rcu_bh". The fields are
+taken from the rcu_state structure, and are as follows:
+
+o "completed" is the number of grace periods that have completed.
+ It is comparable to the "c" field from rcu/rcudata in that a
+ CPU whose "c" field matches the value of "completed" is aware
+ that the corresponding RCU grace period has completed.
+
+o "gpnum" is the number of grace periods that have started. It is
+ comparable to the "g" field from rcu/rcudata in that a CPU
+ whose "g" field matches the value of "gpnum" is aware that the
+ corresponding RCU grace period has started.
+
+ If these two fields are equal (as they are for "rcu_bh" above),
+ then there is no grace period in progress, in other words, RCU
+ is idle. On the other hand, if the two fields differ (as they
+ do for "rcu" above), then an RCU grace period is in progress.
+
+
+The output of "cat rcu/rcuhier" looks as follows, with very long lines:
+
+c=6902 g=6903 s=2 jfq=3 j=72c7 nfqs=13142/nfqsng=0(13142) fqlh=6

+
+This is once again split into "rcu" and "rcu_bh" portions. The fields are
+as follows:
+
+o "c" is exactly the same as "completed" under rcu/rcugp.
+
+o "g" is exactly the same as "gpnum" under rcu/rcugp.
+
+o "s" is the "signaled" state that drives force_quiescent_state()'s
+ state machine.
+
+o "jfq" is the number of jiffies remaining for this grace period
+ before force_quiescent_state() is invoked to help push things
+ along. Note that CPUs in dyntick-idle mode thoughout the grace
+ period will not report on their own, but rather must be check by
+ some other CPU via force_quiescent_state().
+
+o "j" is the low-order four hex digits of the jiffies counter.
+ Yes, Paul did run into a number of problems that turned out to
+ be due to the jiffies counter no longer counting. Why do you ask?
+
+o "nfqs" is the number of calls to force_quiescent_state() since
+ boot.
+
+o "nfqsng" is the number of useless calls to force_quiescent_state(),
+ where there wasn't actually a grace period active. This can
+ happen due to races. The number in parentheses is the difference
+ between "nfqs" and "nfqsng", or the number of times that
+ force_quiescent_state() actually did some real work.
+
+o "fqlh" is the number of calls to force_quiescent_state() that
+ exited immediately (without even being counted in nfqs above)
+ due to contention on ->fqslock.
+
+o Each element of the form "1/1 0:127 ^0" represents one struct
+ rcu_node. Each line represents one level of the hierarchy, from
+ root to leaves. It is best to think of the rcu_data structures
+ as forming yet another level after the leaves. Note that there
+ might be either one, two, or three levels of rcu_node structures,
+ depending on the relationship between CONFIG_RCU_FANOUT and
+ CONFIG_NR_CPUS.
+
+ o The numbers separated by the "/" are the qsmask followed
+ by the qsmaskinit. The qsmask will have one bit
+ set for each entity in the next lower level that
+ has not yet checked in for the current grace period.
+ The qsmaskinit will have one bit for each entity that is
+ currently expected to check in during each grace period.
+ The value of qsmaskinit is assigned to that of qsmask
+ at the beginning of each grace period.
+
+ For example, for "rcu", the qsmask of the first entry
+ of the lowest level is 0x14, meaning that we are still
+ waiting for CPUs 2 and 4 to check in for the current
+ grace period.
+
+ o The numbers separated by the ":" are the range of CPUs
+ served by this struct rcu_node. This can be helpful
+ in working out how the hierarchy is wired together.
+
+ For example, the first entry at the lowest level shows
+ "0:5", indicating that it covers CPUs 0 through 5.
+
+ o The number after the "^" indicates the bit in the
+ next higher level rcu_node structure that this
+ rcu_node structure corresponds to.
+
+ For example, the first entry at the lowest level shows
+ "^0", indicating that it corresponds to bit zero in
+ the first entry at the middle level.

+ MFP Configuration for PXA2xx/PXA3xx Processors
+
+ Eric Miao <eric.miao@marvell.com>
+
+MFP stands for Multi-Function Pin, which is the pin-mux logic on PXA3xx and
+later PXA series processors. This document describes the existing MFP API,
+and how board/platform driver authors could make use of it.
+
+ Basic Concept
+===============
+
+Unlike the GPIO alternate function settings on PXA25x and PXA27x, a new MFP
+mechanism is introduced from PXA3xx to completely move the pin-mux functions
+out of the GPIO controller. In addition to pin-mux configurations, the MFP
+also controls the low power state, driving strength, pull-up/down and event
+detection of each pin. Below is a diagram of internal connections between
+the MFP logic and the remaining SoC peripherals:
+
+ +--------+
+ | |--(GPIO19)--+
+ | GPIO | |
+ | |--(GPIO...) |
+ +--------+ |
+ | +---------+
+ +--------+ +------>| |
+ | PWM2 |--(PWM_OUT)-------->| MFP |
+ +--------+ +------>| |-------> to external PAD
+ | +---->| |
+ +--------+ | | +-->| |
+ | SSP2 |---(TXD)----+ | | +---------+
+ +--------+ | |
+ | |
+ +--------+ | |
+ | Keypad |--(MKOUT4)----+ |
+ +--------+ |
+ |
+ +--------+ |
+ | UART2 |---(TXD)--------+
+ +--------+
+
+NOTE: the external pad is named as MFP_PIN_GPIO19, it doesn't necessarily
+mean it's dedicated for GPIO19, only as a hint that internally this pin
+can be routed from GPIO19 of the GPIO controller.
+
+To better understand the change from PXA25x/PXA27x GPIO alternate function
+to this new MFP mechanism, here are several key points:
+
+ 1. GPIO controller on PXA3xx is now a dedicated controller, same as other
+ internal controllers like PWM, SSP and UART, with 128 internal signals
+ which can be routed to external through one or more MFPs (e.g. GPIO<0>
+ can be routed through either MFP_PIN_GPIO0 as well as MFP_PIN_GPIO0_2,
+ see arch/arm/mach-pxa/mach/include/mfp-pxa300.h)
+
+ 2. Alternate function configuration is removed from this GPIO controller,
+ the remaining functions are pure GPIO-specific, i.e.
+
+ - GPIO signal level control
+ - GPIO direction control
+ - GPIO level change detection
+
+ 3. Low power state for each pin is now controlled by MFP, this means the
+ PGSRx registers on PXA2xx are now useless on PXA3xx
+
+ 4. Wakeup detection is now controlled by MFP, PWER does not control the
+ wakeup from GPIO(s) any more, depending on the sleeping state, ADxER
+ (as defined in pxa3xx-regs.h) controls the wakeup from MFP
+
+NOTE: with such a clear separation of MFP and GPIO, by GPIO<xx> we normally
+mean it is a GPIO signal, and by MFP<xxx> or pin xxx, we mean a physical
+pad (or ball).
+
+ MFP API Usage
+===============
+
+For board code writers, here are some guidelines:
+
+1. include ONE of the following header files in your <board>.c:
+
+ - #include <mach/mfp-pxa25x.h>
+ - #include <mach/mfp-pxa27x.h>
+ - #include <mach/mfp-pxa300.h>
+ - #include <mach/mfp-pxa320.h>
+ - #include <mach/mfp-pxa930.h>
+
+ NOTE: only one file in your <board>.c, depending on the processors used,
+ because pin configuration definitions may conflict in these file (i.e.
+ same name, different meaning and settings on different processors). E.g.
+ for zylonite platform, which support both PXA300/PXA310 and PXA320, two
+ separate files are introduced: zylonite_pxa300.c and zylonite_pxa320.c
+ (in addition to handle MFP configuration differences, they also handle
+ the other differences between the two combinations).
+
+ NOTE: PXA300 and PXA310 are almost identical in pin configurations (with
+ PXA310 supporting some additional ones), thus the difference is actually
+ covered in a single mfp-pxa300.h.
+
+2. prepare an array for the initial pin configurations, e.g.:
+
+ static unsigned long mainstone_pin_config[] __initdata = {
+ /* Chip Select */
+ GPIO15_nCS_1,
+
+ /* LCD - 16bpp Active TFT */
+ GPIOxx_TFT_LCD_16BPP,
+ GPIO16_PWM0_OUT, /* Backlight */
+
+ /* MMC */
+ GPIO32_MMC_CLK,
+ GPIO112_MMC_CMD,
+ GPIO92_MMC_DAT_0,
+ GPIO109_MMC_DAT_1,
+ GPIO110_MMC_DAT_2,
+ GPIO111_MMC_DAT_3,
+
+ ...
+
+ /* GPIO */
+ GPIO1_GPIO | WAKEUP_ON_EDGE_BOTH,
+ };
+
+ a) once the pin configurations are passed to pxa{2xx,3xx}_mfp_config(),
+ and written to the actual registers, they are useless and may discard,
+ adding '__initdata' will help save some additional bytes here.
+
+ b) when there is only one possible pin configurations for a component,
+ some simplified definitions can be used, e.g. GPIOxx_TFT_LCD_16BPP on
+ PXA25x and PXA27x processors
+
+ c) if by board design, a pin can be configured to wake up the system
+ from low power state, it can be 'OR'ed with any of:
+
+ WAKEUP_ON_EDGE_BOTH
+ WAKEUP_ON_EDGE_RISE
+ WAKEUP_ON_EDGE_FALL
+ WAKEUP_ON_LEVEL_HIGH - specifically for enabling of keypad GPIOs,
+
+ to indicate that this pin has the capability of wake-up the system,
+ and on which edge(s). This, however, doesn't necessarily mean the
+ pin _will_ wakeup the system, it will only when set_irq_wake() is
+ invoked with the corresponding GPIO IRQ (GPIO_IRQ(xx) or gpio_to_irq())
+ and eventually calls gpio_set_wake() for the actual register setting.
+
+ d) although PXA3xx MFP supports edge detection on each pin, the
+ internal logic will only wakeup the system when those specific bits
+ in ADxER registers are set, which can be well mapped to the
+ corresponding peripheral, thus set_irq_wake() can be called with
+ the peripheral IRQ to enable the wakeup.
+
+
+ MFP on PXA3xx
+===============
+
+Every external I/O pad on PXA3xx (excluding those for special purpose) has
+one MFP logic associated, and is controlled by one MFP register (MFPR).
+
+The MFPR has the following bit definitions (for PXA300/PXA310/PXA320):
+
+ 31 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
+ +-------------------------+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
+ | RESERVED |PS|PU|PD| DRIVE |SS|SD|SO|EC|EF|ER|--| AF_SEL |
+ +-------------------------+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
+
+ Bit 3: RESERVED
+ Bit 4: EDGE_RISE_EN - enable detection of rising edge on this pin
+ Bit 5: EDGE_FALL_EN - enable detection of falling edge on this pin
+ Bit 6: EDGE_CLEAR - disable edge detection on this pin
+ Bit 7: SLEEP_OE_N - enable outputs during low power modes
+ Bit 8: SLEEP_DATA - output data on the pin during low power modes
+ Bit 9: SLEEP_SEL - selection control for low power modes signals
+ Bit 13: PULLDOWN_EN - enable the internal pull-down resistor on this pin
+ Bit 14: PULLUP_EN - enable the internal pull-up resistor on this pin
+ Bit 15: PULL_SEL - pull state controlled by selected alternate function
+ (0) or by PULL{UP,DOWN}_EN bits (1)
+
+ Bit 0 - 2: AF_SEL - alternate function selection, 8 possibilities, from 0-7
+ Bit 10-12: DRIVE - drive strength and slew rate
+ 0b000 - fast 1mA
+ 0b001 - fast 2mA
+ 0b002 - fast 3mA
+ 0b003 - fast 4mA
+ 0b004 - slow 6mA
+ 0b005 - fast 6mA
+ 0b006 - slow 10mA
+ 0b007 - fast 10mA
+
+ MFP Design for PXA2xx/PXA3xx
+==============================
+
+Due to the difference of pin-mux handling between PXA2xx and PXA3xx, a unified
+MFP API is introduced to cover both series of processors.
+
+The basic idea of this design is to introduce definitions for all possible pin
+configurations, these definitions are processor and platform independent, and
+the actual API invoked to convert these definitions into register settings and
+make them effective there-after.

+
+ Pin Configuration
+ -----------------
+
+ The following comments are copied from mfp.h (see the actual source code
+ for most updated info)
+
+ /*
+ * a possible MFP configuration is represented by a 32-bit integer
+ *
+ * bit 0.. 9 - MFP Pin Number (1024 Pins Maximum)
+ * bit 10..12 - Alternate Function Selection
+ * bit 13..15 - Drive Strength
+ * bit 16..18 - Low Power Mode State
+ * bit 19..20 - Low Power Mode Edge Detection
+ * bit 21..22 - Run Mode Pull State
+ *
+ * to facilitate the definition, the following macros are provided
+ *
+ * MFP_CFG_DEFAULT - default MFP configuration value, with
+ * alternate function = 0,
+ * drive strength = fast 3mA (MFP_DS03X)
+ * low power mode = default
+ * edge detection = none
+ *
+ * MFP_CFG - default MFPR value with alternate function
+ * MFP_CFG_DRV - default MFPR value with alternate function and
+ * pin drive strength
+ * MFP_CFG_LPM - default MFPR value with alternate function and
+ * low power mode
+ * MFP_CFG_X - default MFPR value with alternate function,
+ * pin drive strength and low power mode
+ */
+
+ Examples of pin configurations are:
+
+ #define GPIO94_SSP3_RXD MFP_CFG_X(GPIO94, AF1, DS08X, FLOAT)
+
+ which reads GPIO94 can be configured as SSP3_RXD, with alternate function
+ selection of 1, driving strength of 0b101, and a float state in low power
+ modes.
+
+ NOTE: this is the default setting of this pin being configured as SSP3_RXD
+ which can be modified a bit in board code, though it is not recommended to
+ do so, simply because this default setting is usually carefully encoded,
+ and is supposed to work in most cases.
+
+ Register Settings
+ -----------------
+
+ Register settings on PXA3xx for a pin configuration is actually very
+ straight-forward, most bits can be converted directly into MFPR value
+ in a easier way. Two sets of MFPR values are calculated: the run-time
+ ones and the low power mode ones, to allow different settings.
+
+ The conversion from a generic pin configuration to the actual register
+ settings on PXA2xx is a bit complicated: many registers are involved,
+ including GAFRx, GPDRx, PGSRx, PWER, PKWR, PFER and PRER. Please see
+ mfp-pxa2xx.c for how the conversion is made.

+ CREDENTIALS IN LINUX
+ ====================
+
+By: David Howells <dhowells@redhat.com>

+

+
+ (*) File markings.
+
+ (*) Task credentials.
+
+ - Immutable credentials.
+ - Accessing task credentials.

+ - Managing credentials.
+
+ (*) Open file credentials.
+
+ (*) Overriding the VFS's use of credentials.
+
+
+========
+OVERVIEW
+========
+
+There are several parts to the security check performed by Linux when one
+object acts upon another:
+
+ (1) Objects.
+
+ Objects are things in the system that may be acted upon directly by
+ userspace programs. Linux has a variety of actionable objects, including:
+
+ - Tasks
+ - Files/inodes
+ - Sockets
+ - Message queues
+ - Shared memory segments
+ - Semaphores
+ - Keys
+
+ As a part of the description of all these objects there is a set of
+ credentials. What's in the set depends on the type of object.
+
+ (2) Object ownership.
+
+ Amongst the credentials of most objects, there will be a subset that
+ indicates the ownership of that object. This is used for resource
+ accounting and limitation (disk quotas and task rlimits for example).
+
+ In a standard UNIX filesystem, for instance, this will be defined by the
+ UID marked on the inode.
+
+ (3) The objective context.
+
+ Also amongst the credentials of those objects, there will be a subset that
+ indicates the 'objective context' of that object. This may or may not be
+ the same set as in (2) - in standard UNIX files, for instance, this is the
+ defined by the UID and the GID marked on the inode.
+
+ The objective context is used as part of the security calculation that is
+ carried out when an object is acted upon.
+
+ (4) Subjects.
+
+ A subject is an object that is acting upon another object.
+
+ Most of the objects in the system are inactive: they don't act on other
+ objects within the system. Processes/tasks are the obvious exception:
+ they do stuff; they access and manipulate things.
+
+ Objects other than tasks may under some circumstances also be subjects.
+ For instance an open file may send SIGIO to a task using the UID and EUID
+ given to it by a task that called fcntl(F_SETOWN) upon it. In this case,
+ the file struct will have a subjective context too.
+
+ (5) The subjective context.
+
+ A subject has an additional interpretation of its credentials. A subset
+ of its credentials forms the 'subjective context'. The subjective context
+ is used as part of the security calculation that is carried out when a
+ subject acts.
+
+ A Linux task, for example, has the FSUID, FSGID and the supplementary
+ group list for when it is acting upon a file - which are quite separate
+ from the real UID and GID that normally form the objective context of the
+ task.
+
+ (6) Actions.
+
+ Linux has a number of actions available that a subject may perform upon an
+ object. The set of actions available depends on the nature of the subject
+ and the object.
+
+ Actions include reading, writing, creating and deleting files; forking or
+ signalling and tracing tasks.
+
+ (7) Rules, access control lists and security calculations.
+
+ When a subject acts upon an object, a security calculation is made. This
+ involves taking the subjective context, the objective context and the
+ action, and searching one or more sets of rules to see whether the subject
+ is granted or denied permission to act in the desired manner on the
+ object, given those contexts.
+
+ There are two main sources of rules:
+
+ (a) Discretionary access control (DAC):
+
+ Sometimes the object will include sets of rules as part of its
+ description. This is an 'Access Control List' or 'ACL'. A Linux
+ file may supply more than one ACL.
+
+ A traditional UNIX file, for example, includes a permissions mask that
+ is an abbreviated ACL with three fixed classes of subject ('user',
+ 'group' and 'other'), each of which may be granted certain privileges
+ ('read', 'write' and 'execute' - whatever those map to for the object
+ in question). UNIX file permissions do not allow the arbitrary
+ specification of subjects, however, and so are of limited use.
+
+ A Linux file might also sport a POSIX ACL. This is a list of rules
+ that grants various permissions to arbitrary subjects.
+
+ (b) Mandatory access control (MAC):
+
+ The system as a whole may have one or more sets of rules that get
+ applied to all subjects and objects, regardless of their source.
+ SELinux and Smack are examples of this.
+
+ In the case of SELinux and Smack, each object is given a label as part
+ of its credentials. When an action is requested, they take the
+ subject label, the object label and the action and look for a rule
+ that says that this action is either granted or denied.
+
+
+====================
+TYPES OF CREDENTIALS
+====================
+
+The Linux kernel supports the following types of credentials:
+
+ (1) Traditional UNIX credentials.
+
+ Real User ID
+ Real Group ID
+
+ The UID and GID are carried by most, if not all, Linux objects, even if in
+ some cases it has to be invented (FAT or CIFS files for example, which are
+ derived from Windows). These (mostly) define the objective context of
+ that object, with tasks being slightly different in some cases.
+
+ Effective, Saved and FS User ID
+ Effective, Saved and FS Group ID
+ Supplementary groups
+
+ These are additional credentials used by tasks only. Usually, an
+ EUID/EGID/GROUPS will be used as the subjective context, and real UID/GID
+ will be used as the objective. For tasks, it should be noted that this is
+ not always true.
+
+ (2) Capabilities.
+
+ Set of permitted capabilities
+ Set of inheritable capabilities
+ Set of effective capabilities
+ Capability bounding set
+
+ These are only carried by tasks. They indicate superior capabilities
+ granted piecemeal to a task that an ordinary task wouldn't otherwise have.
+ These are manipulated implicitly by changes to the traditional UNIX
+ credentials, but can also be manipulated directly by the capset() system
+ call.
+
+ The permitted capabilities are those caps that the process might grant
+ itself to its effective or permitted sets through capset(). This
+ inheritable set might also be so constrained.
+
+ The effective capabilities are the ones that a task is actually allowed to
+ make use of itself.
+
+ The inheritable capabilities are the ones that may get passed across
+ execve().
+
+ The bounding set limits the capabilities that may be inherited across
+ execve(), especially when a binary is executed that will execute as UID 0.
+
+ (3) Secure management flags (securebits).
+
+ These are only carried by tasks. These govern the way the above
+ credentials are manipulated and inherited over certain operations such as
+ execve(). They aren't used directly as objective or subjective
+ credentials.
+
+ (4) Keys and keyrings.
+
+ These are only carried by tasks. They carry and cache security tokens
+ that don't fit into the other standard UNIX credentials. They are for
+ making such things as network filesystem keys available to the file
+ accesses performed by processes, without the necessity of ordinary
+ programs having to know about security details involved.
+
+ Keyrings are a special type of key. They carry sets of other keys and can
+ be searched for the desired key. Each process may subscribe to a number
+ of keyrings:
+
+ Per-thread keying
+ Per-process keyring
+ Per-session keyring
+
+ When a process accesses a key, if not already present, it will normally be
+ cached on one of these keyrings for future accesses to find.
+
+ For more information on using keys, see Documentation/keys.txt.
+
+ (5) LSM
+
+ The Linux Security Module allows extra controls to be placed over the
+ operations that a task may do. Currently Linux supports two main
+ alternate LSM options: SELinux and Smack.
+
+ Both work by labelling the objects in a system and then applying sets of
+ rules (policies) that say what operations a task with one label may do to
+ an object with another label.
+
+ (6) AF_KEY
+
+ This is a socket-based approach to credential management for networking
+ stacks [RFC 2367]. It isn't discussed by this document as it doesn't
+ interact directly with task and file credentials; rather it keeps system
+ level credentials.
+
+
+When a file is opened, part of the opening task's subjective context is
+recorded in the file struct created. This allows operations using that file
+struct to use those credentials instead of the subjective context of the task
+that issued the operation. An example of this would be a file opened on a
+network filesystem where the credentials of the opened file should be presented
+to the server, regardless of who is actually doing a read or a write upon it.
+
+
+=============
+FILE MARKINGS
+=============
+
+Files on disk or obtained over the network may have annotations that form the
+objective security context of that file. Depending on the type of filesystem,
+this may include one or more of the following:
+
+ (*) UNIX UID, GID, mode;
+
+ (*) Windows user ID;
+
+ (*) Access control list;
+
+ (*) LSM security label;
+
+ (*) UNIX exec privilege escalation bits (SUID/SGID);
+
+ (*) File capabilities exec privilege escalation bits.
+
+These are compared to the task's subjective security context, and certain
+operations allowed or disallowed as a result. In the case of execve(), the
+privilege escalation bits come into play, and may allow the resulting process
+extra privileges, based on the annotations on the executable file.
+
+
+================
+TASK CREDENTIALS
+================
+
+In Linux, all of a task's credentials are held in (uid, gid) or through
+(groups, keys, LSM security) a refcounted structure of type 'struct cred'.
+Each task points to its credentials by a pointer called 'cred' in its
+task_struct.
+
+Once a set of credentials has been prepared and committed, it may not be
+changed, barring the following exceptions:
+
+ (1) its reference count may be changed;
+
+ (2) the reference count on the group_info struct it points to may be changed;
+
+ (3) the reference count on the security data it points to may be changed;
+
+ (4) the reference count on any keyrings it points to may be changed;
+
+ (5) any keyrings it points to may be revoked, expired or have their security
+ attributes changed; and
+
+ (6) the contents of any keyrings to which it points may be changed (the whole
+ point of keyrings being a shared set of credentials, modifiable by anyone
+ with appropriate access).
+
+To alter anything in the cred struct, the copy-and-replace principle must be
+adhered to. First take a copy, then alter the copy and then use RCU to change
+the task pointer to make it point to the new copy. There are wrappers to aid
+with this (see below).
+
+A task may only alter its _own_ credentials; it is no longer permitted for a
+task to alter another's credentials. This means the capset() system call is no
+longer permitted to take any PID other than the one of the current process.
+Also keyctl_instantiate() and keyctl_negate() functions no longer permit
+attachment to process-specific keyrings in the requesting process as the
+instantiating process may need to create them.
+
+
+IMMUTABLE CREDENTIALS
+---------------------
+
+Once a set of credentials has been made public (by calling commit_creds() for
+example), it must be considered immutable, barring two exceptions:
+
+ (1) The reference count may be altered.
+
+ (2) Whilst the keyring subscriptions of a set of credentials may not be
+ changed, the keyrings subscribed to may have their contents altered.
+
+To catch accidental credential alteration at compile time, struct task_struct
+has _const_ pointers to its credential sets, as does struct file. Furthermore,
+certain functions such as get_cred() and put_cred() operate on const pointers,
+thus rendering casts unnecessary, but require to temporarily ditch the const
+qualification to be able to alter the reference count.
+
+
+ACCESSING TASK CREDENTIALS
+--------------------------
+
+A task being able to alter only its own credentials permits the current process
+to read or replace its own credentials without the need for any form of locking
+- which simplifies things greatly. It can just call:
+
+ const struct cred *current_cred()
+
+to get a pointer to its credentials structure, and it doesn't have to release
+it afterwards.
+
+There are convenience wrappers for retrieving specific aspects of a task's
+credentials (the value is simply returned in each case):
+
+ uid_t current_uid(void) Current's real UID
+ gid_t current_gid(void) Current's real GID
+ uid_t current_euid(void) Current's effective UID
+ gid_t current_egid(void) Current's effective GID
+ uid_t current_fsuid(void) Current's file access UID
+ gid_t current_fsgid(void) Current's file access GID
+ kernel_cap_t current_cap(void) Current's effective capabilities
+ void *current_security(void) Current's LSM security pointer
+ struct user_struct *current_user(void) Current's user account
+
+There are also convenience wrappers for retrieving specific associated pairs of
+a task's credentials:
+
+ void current_uid_gid(uid_t *, gid_t *);
+ void current_euid_egid(uid_t *, gid_t *);
+ void current_fsuid_fsgid(uid_t *, gid_t *);
+
+which return these pairs of values through their arguments after retrieving
+them from the current task's credentials.
+
+
+In addition, there is a function for obtaining a reference on the current
+process's current set of credentials:
+
+ const struct cred *get_current_cred(void);
+
+and functions for getting references to one of the credentials that don't
+actually live in struct cred:
+
+ struct user_struct *get_current_user(void);
+ struct group_info *get_current_groups(void);
+
+which get references to the current process's user accounting structure and
+supplementary groups list respectively.
+
+Once a reference has been obtained, it must be released with put_cred(),
+free_uid() or put_group_info() as appropriate.
+
+
+ACCESSING ANOTHER TASK'S CREDENTIALS
+------------------------------------
+
+Whilst a task may access its own credentials without the need for locking, the
+same is not true of a task wanting to access another task's credentials. It
+must use the RCU read lock and rcu_dereference().
+
+The rcu_dereference() is wrapped by:
+
+ const struct cred *__task_cred(struct task_struct *task);
+
+This should be used inside the RCU read lock, as in the following example:
+
+ void foo(struct task_struct *t, struct foo_data *f)
+ {
+ const struct cred *tcred;
+ ...
+ rcu_read_lock();
+ tcred = __task_cred(t);
+ f->uid = tcred->uid;
+ f->gid = tcred->gid;
+ f->groups = get_group_info(tcred->groups);
+ rcu_read_unlock();
+ ...
+ }
+
+A function need not get RCU read lock to use __task_cred() if it is holding a
+spinlock at the time as this implicitly holds the RCU read lock.
+
+Should it be necessary to hold another task's credentials for a long period of
+time, and possibly to sleep whilst doing so, then the caller should get a
+reference on them using:
+
+ const struct cred *get_task_cred(struct task_struct *task);
+
+This does all the RCU magic inside of it. The caller must call put_cred() on
+the credentials so obtained when they're finished with.
+
+There are a couple of convenience functions to access bits of another task's
+credentials, hiding the RCU magic from the caller:
+
+ uid_t task_uid(task) Task's real UID
+ uid_t task_euid(task) Task's effective UID
+
+If the caller is holding a spinlock or the RCU read lock at the time anyway,
+then:
+
+ __task_cred(task)->uid
+ __task_cred(task)->euid
+
+should be used instead. Similarly, if multiple aspects of a task's credentials
+need to be accessed, RCU read lock or a spinlock should be used, __task_cred()
+called, the result stored in a temporary pointer and then the credential
+aspects called from that before dropping the lock. This prevents the
+potentially expensive RCU magic from being invoked multiple times.
+
+Should some other single aspect of another task's credentials need to be
+accessed, then this can be used:
+
+ task_cred_xxx(task, member)
+
+where 'member' is a non-pointer member of the cred struct. For instance:
+
+ uid_t task_cred_xxx(task, suid);
+
+will retrieve 'struct cred::suid' from the task, doing the appropriate RCU
+magic. This may not be used for pointer members as what they point to may
+disappear the moment the RCU read lock is dropped.
+
+
+ALTERING CREDENTIALS
+--------------------
+
+As previously mentioned, a task may only alter its own credentials, and may not
+alter those of another task. This means that it doesn't need to use any
+locking to alter its own credentials.
+
+To alter the current process's credentials, a function should first prepare a
+new set of credentials by calling:
+
+ struct cred *prepare_creds(void);
+
+this locks current->cred_replace_mutex and then allocates and constructs a
+duplicate of the current process's credentials, returning with the mutex still
+held if successful. It returns NULL if not successful (out of memory).
+
+The mutex prevents ptrace() from altering the ptrace state of a process whilst
+security checks on credentials construction and changing is taking place as
+the ptrace state may alter the outcome, particularly in the case of execve().
+
+The new credentials set should be altered appropriately, and any security
+checks and hooks done. Both the current and the proposed sets of credentials
+are available for this purpose as current_cred() will return the current set
+still at this point.
+
+
+When the credential set is ready, it should be committed to the current process
+by calling:
+
+ int commit_creds(struct cred *new);
+
+This will alter various aspects of the credentials and the process, giving the
+LSM a chance to do likewise, then it will use rcu_assign_pointer() to actually
+commit the new credentials to current->cred, it will release
+current->cred_replace_mutex to allow ptrace() to take place, and it will notify
+the scheduler and others of the changes.
+
+This function is guaranteed to return 0, so that it can be tail-called at the
+end of such functions as sys_setresuid().
+
+Note that this function consumes the caller's reference to the new credentials.
+The caller should _not_ call put_cred() on the new credentials afterwards.
+
+Furthermore, once this function has been called on a new set of credentials,
+those credentials may _not_ be changed further.
+
+
+Should the security checks fail or some other error occur after prepare_creds()
+has been called, then the following function should be invoked:
+
+ void abort_creds(struct cred *new);
+
+This releases the lock on current->cred_replace_mutex that prepare_creds() got
+and then releases the new credentials.
+
+
+A typical credentials alteration function would look something like this:
+
+ int alter_suid(uid_t suid)
+ {
+ struct cred *new;
+ int ret;
+
+ new = prepare_creds();
+ if (!new)
+ return -ENOMEM;
+
+ new->suid = suid;
+ ret = security_alter_suid(new);
+ if (ret < 0) {
+ abort_creds(new);
+ return ret;
+ }
+
+ return commit_creds(new);
+ }
+
+
+MANAGING CREDENTIALS
+--------------------
+
+There are some functions to help manage credentials:
+
+ (*) void put_cred(const struct cred *cred);
+
+ This releases a reference to the given set of credentials. If the
+ reference count reaches zero, the credentials will be scheduled for
+ destruction by the RCU system.
+
+ (*) const struct cred *get_cred(const struct cred *cred);
+
+ This gets a reference on a live set of credentials, returning a pointer to
+ that set of credentials.
+
+ (*) struct cred *get_new_cred(struct cred *cred);
+
+ This gets a reference on a set of credentials that is under construction
+ and is thus still mutable, returning a pointer to that set of credentials.
+
+
+=====================
+OPEN FILE CREDENTIALS
+=====================
+
+When a new file is opened, a reference is obtained on the opening task's
+credentials and this is attached to the file struct as 'f_cred' in place of
+'f_uid' and 'f_gid'. Code that used to access file->f_uid and file->f_gid
+should now access file->f_cred->fsuid and file->f_cred->fsgid.
+
+It is safe to access f_cred without the use of RCU or locking because the
+pointer will not change over the lifetime of the file struct, and nor will the
+contents of the cred struct pointed to, barring the exceptions listed above
+(see the Task Credentials section).
+
+
+=======================================
+OVERRIDING THE VFS'S USE OF CREDENTIALS
+=======================================
+
+Under some circumstances it is desirable to override the credentials used by
+the VFS, and that can be done by calling into such as vfs_mkdir() with a
+different set of credentials. This is done in the following places:
+
+ (*) sys_faccessat().
+
+ (*) do_coredump().
+
+ (*) nfs4recover.c.

+Overlay Support for PXA27x and later LCD controllers
+====================================================
+
+ PXA27x and later processors support overlay1 and overlay2 on-top of the
+ base framebuffer (although under-neath the base is also possible). They
+ support palette and no-palette RGB formats, as well as YUV formats (only
+ available on overlay2). These overlays have dedicated DMA channels and
+ behave in a similar way as a framebuffer.
+
+ However, there are some differences between these overlay framebuffers
+ and normal framebuffers, as listed below:
+
+ 1. overlay can start at a 32-bit word aligned position within the base
+ framebuffer, which means they have a start (x, y). This information
+ is encoded into var->nonstd (no, var->xoffset and var->yoffset are
+ not for such purpose).
+
+ 2. overlay framebuffer is allocated dynamically according to specified
+ 'struct fb_var_screeninfo', the amount is decided by:
+
+ var->xres_virtual * var->yres_virtual * bpp
+
+ bpp = 16 -- for RGB565 or RGBT555
+ = 24 -- for YUV444 packed
+ = 24 -- for YUV444 planar
+ = 16 -- for YUV422 planar (1 pixel = 1 Y + 1/2 Cb + 1/2 Cr)
+ = 12 -- for YUV420 planar (1 pixel = 1 Y + 1/4 Cb + 1/4 Cr)
+
+ NOTE:
+
+ a. overlay does not support panning in x-direction, thus
+ var->xres_virtual will always be equal to var->xres
+
+ b. line length of overlay(s) must be on a 32-bit word boundary,
+ for YUV planar modes, it is a requirement for the component
+ with minimum bits per pixel, e.g. for YUV420, Cr component
+ for one pixel is actually 2-bits, it means the line length
+ should be a multiple of 16-pixels
+
+ c. starting horizontal position (XPOS) should start on a 32-bit
+ word boundary, otherwise the fb_check_var() will just fail.
+
+ d. the rectangle of the overlay should be within the base plane,
+ otherwise fail
+
+ Applications should follow the sequence below to operate an overlay
+ framebuffer:
+
+ a. open("/dev/fb[1-2]", ...)
+ b. ioctl(fd, FBIOGET_VSCREENINFO, ...)
+ c. modify 'var' with desired parameters:
+ 1) var->xres and var->yres
+ 2) larger var->yres_virtual if more memory is required,
+ usually for double-buffering
+ 3) var->nonstd for starting (x, y) and color format
+ 4) var->{red, green, blue, transp} if RGB mode is to be used
+ d. ioctl(fd, FBIOPUT_VSCREENINFO, ...)
+ e. ioctl(fd, FBIOGET_FSCREENINFO, ...)
+ f. mmap
+ g. ...
+
+ 3. for YUV planar formats, these are actually not supported within the
+ framebuffer framework, application has to take care of the offsets
+ and lengths of each component within the framebuffer.
+
+ 4. var->nonstd is used to pass starting (x, y) position and color format,

+we want the users in a user namespace to be children of the user
+who created it.

+That is currently unimplemented. So instead, every user in a new

+Chelsio S3 iSCSI Driver for Linux
+
+Introduction
+============
+
+The Chelsio T3 ASIC based Adapters (S310, S320, S302, S304, Mezz cards, etc.
+series of products) supports iSCSI acceleration and iSCSI Direct Data Placement
+(DDP) where the hardware handles the expensive byte touching operations, such
+as CRC computation and verification, and direct DMA to the final host memory
+destination:
+
+ - iSCSI PDU digest generation and verification
+
+ On transmitting, Chelsio S3 h/w computes and inserts the Header and
+ Data digest into the PDUs.
+ On receiving, Chelsio S3 h/w computes and verifies the Header and
+ Data digest of the PDUs.
+
+ - Direct Data Placement (DDP)
+
+ S3 h/w can directly place the iSCSI Data-In or Data-Out PDU's
+ payload into pre-posted final destination host-memory buffers based
+ on the Initiator Task Tag (ITT) in Data-In or Target Task Tag (TTT)
+ in Data-Out PDUs.
+
+ - PDU Transmit and Recovery
+
+ On transmitting, S3 h/w accepts the complete PDU (header + data)
+ from the host driver, computes and inserts the digests, decomposes
+ the PDU into multiple TCP segments if necessary, and transmit all
+ the TCP segments onto the wire. It handles TCP retransmission if
+ needed.
+
+ On receving, S3 h/w recovers the iSCSI PDU by reassembling TCP
+ segments, separating the header and data, calculating and verifying
+ the digests, then forwards the header to the host. The payload data,
+ if possible, will be directly placed into the pre-posted host DDP
+ buffer. Otherwise, the payload data will be sent to the host too.
+
+The cxgb3i driver interfaces with open-iscsi initiator and provides the iSCSI
+acceleration through Chelsio hardware wherever applicable.
+
+Using the cxgb3i Driver
+=======================
+
+The following steps need to be taken to accelerates the open-iscsi initiator:
+
+1. Load the cxgb3i driver: "modprobe cxgb3i"
+
+ The cxgb3i module registers a new transport class "cxgb3i" with open-iscsi.
+
+ * in the case of recompiling the kernel, the cxgb3i selection is located at
+ Device Drivers
+ SCSI device support --->
+ [*] SCSI low-level drivers --->
+ <M> Chelsio S3xx iSCSI support
+
+2. Create an interface file located under /etc/iscsi/ifaces/ for the new
+ transport class "cxgb3i".
+
+ The content of the file should be in the following format:
+ iface.transport_name = cxgb3i
+ iface.net_ifacename = <ethX>
+ iface.ipaddress = <iscsi ip address>
+
+ * if iface.ipaddress is specified, <iscsi ip address> needs to be either the
+ same as the ethX's ip address or an address on the same subnet. Make
+ sure the ip address is unique in the network.
+
+3. edit /etc/iscsi/iscsid.conf
+ The default setting for MaxRecvDataSegmentLength (131072) is too big,
+ replace "node.conn[0].iscsi.MaxRecvDataSegmentLength" to be a value no
+ bigger than 15360 (for example 8192):
+
+ node.conn[0].iscsi.MaxRecvDataSegmentLength = 8192
+
+ * The login would fail for a normal session if MaxRecvDataSegmentLength is
+ too big. A error message in the format of
+ "cxgb3i: ERR! MaxRecvSegmentLength <X> too big. Need to be <= <Y>."
+ would be logged to dmesg.
+
+4. To direct open-iscsi traffic to go through cxgb3i's accelerated path,
+ "-I <iface file name>" option needs to be specified with most of the
+ iscsiadm command. <iface file name> is the transport interface file created
+ in step 2.

-
-This file describes the configuration and behavior of KGDB for the SH
-kernel. Based on a description from Henry Bell <henry.bell@st.com>, it
-has been modified to account for quirks in the current implementation.
-
-Version
-=======
-
-This version of KGDB was written for 2.4.xx kernels for the SH architecture.
-Further documentation is available from the linux-sh project website.
-
-
-Debugging Setup: Host
-======================
-
-The two machines will be connected together via a serial line - this
-should be a null modem cable i.e. with a twist.
-
-On your DEVELOPMENT machine, go to your kernel source directory and
-build the kernel, enabling KGDB support in the "kernel hacking" section.
-This includes the KGDB code, and also makes the kernel be compiled with
-the "-g" option set -- necessary for debugging.
-
-To install this new kernel, use the following installation procedure.
-
-Decide on which tty port you want the machines to communicate, then
-cable them up back-to-back using the null modem. On the DEVELOPMENT
-machine, you may wish to create an initialization file called .gdbinit
-(in the kernel source directory or in your home directory) to execute
-commonly-used commands at startup.
-
-A minimal .gdbinit might look like this:
-
- file vmlinux
- set remotebaud 115200
- target remote /dev/ttyS0
-
-Change the "target" definition so that it specifies the tty port that
-you intend to use. Change the "remotebaud" definition to match the
-data rate that you are going to use for the com line (115200 is the
-default).
-
-Debugging Setup: Target
-========================
-
-By default, the KGDB stub will communicate with the host GDB using
-ttySC1 at 115200 baud, 8 databits, no parity; these defaults can be
-changed in the kernel configuration. As the kernel starts up, KGDB will
-initialize so that breakpoints, kernel segfaults, and so forth will
-generally enter the debugger.
-
-This behavior can be modified by including the "kgdb" option in the
-kernel command line; this option has the general form:
-
- kgdb=<ttyspec>,<action>
-
-The <ttyspec> indicates the port to use, and can optionally specify
-baud, parity and databits -- e.g. "ttySC0,9600N8" or "ttySC1,19200".
-
-The <action> can be "halt" or "disabled". The "halt" action enters the
-debugger via a breakpoint as soon as kgdb is initialized; the "disabled"
-action causes kgdb to ignore kernel segfaults and such until explicitly
-entered by a breakpoint in the code or by external action (sysrq or NMI).
-
-(Both <ttyspec> and <action> can appear alone, w/o the separating comma.)
-
-For example, if you wish to debug early in kernel startup code, you
-might specify the halt option:
-
- kgdb=halt
-
-Boot the TARGET machine, which will appear to hang.
-
-On your DEVELOPMENT machine, cd to the source directory and run the gdb
-program. (This is likely to be a cross GDB which runs on your host but
-is built for an SH target.) If everything is working correctly you
-should see gdb print out a few lines indicating that a breakpoint has
-been taken. It will actually show a line of code in the target kernel
-inside the gdbstub activation code.
-
-NOTE: BE SURE TO TERMINATE OR SUSPEND any other host application which
-may be using the same serial port (for example, a terminal emulator you
-have been using to connect to the target boot code.) Otherwise, data
-from the target may not all get to GDB!
-
-You can now use whatever gdb commands you like to set breakpoints.
-Enter "continue" to start your target machine executing again. At this
-point the target system will run at full speed until it encounters
-your breakpoint or gets a segment violation in the kernel, or whatever.
-
-Serial Ports: KGDB, Console
-============================
-
-This version of KGDB may not gracefully handle conflict with other
-drivers in the kernel using the same port. If KGDB is configured on the
-same port (and with the same parameters) as the kernel console, or if
-CONFIG_SH_KGDB_CONSOLE is configured, things should be fine (though in
-some cases console messages may appear twice through GDB). But if the
-KGDB port is not the kernel console and used by another serial driver
-which assumes different serial parameters (e.g. baud rate) KGDB may not
-recover.
-
-Also, when KGDB is entered via sysrq-g (requires CONFIG_KGDB_SYSRQ) and
-the kgdb port uses the same port as the console, detaching GDB will not
-restore the console to working order without the port being re-opened.
-
-Another serious consequence of this is that GDB currently CANNOT break
-into KGDB externally (e.g. via ^C or <BREAK>); unless a breakpoint or
-error is encountered, the only way to enter KGDB after the initial halt
-(see above) is via NMI (CONFIG_KGDB_NMI) or sysrq-g (CONFIG_KGDB_SYSRQ).
-
-Code is included for the basic Hitachi Solution Engine boards to allow
-the use of ttyS0 for KGDB if desired; this is less robust, but may be
-useful in some cases. (This cannot be selected using the config file,
-but only through the kernel command line, e.g. "kgdb=ttyS0", though the
-configured defaults for baud rate etc. still apply if not overridden.)
-
-If gdbstub Does Not Work
-========================
-
-If it doesn't work, you will have to troubleshoot it. Do the easy
-things first like double checking your cabling and data rates. You
-might try some non-kernel based programs to see if the back-to-back
-connection works properly. Just something simple like cat /etc/hosts
-/dev/ttyS0 on one machine and cat /dev/ttyS0 on the other will tell you
-if you can send data from one machine to the other. There is no point
-in tearing out your hair in the kernel if the line doesn't work.
-
-If you need to debug the GDB/KGDB communication itself, the gdb commands
-"set debug remote 1" and "set debug serial 1" may be useful, but be
-warned: they produce a lot of output.
-
-Threads
-=======
-
-Each process in a target machine is seen as a gdb thread. gdb thread related
-commands (info threads, thread n) can be used. CONFIG_KGDB_THREAD must
-be defined for this to work.
-
-In this version, kgdb reports PID_MAX (32768) as the process ID for the
-idle process (pid 0), since GDB does not accept 0 as an ID.
-
-Detaching (exiting KGDB)
-=========================
-
-There are two ways to resume full-speed target execution: "continue" and
-"detach". With "continue", GDB inserts any specified breakpoints in the
-target code and resumes execution; the target is still in "gdb mode".
-If a breakpoint or other debug event (e.g. NMI) happens, the target
-halts and communicates with GDB again, which is waiting for it.
-
-With "detach", GDB does *not* insert any breakpoints; target execution
-is resumed and GDB stops communicating (does not wait for the target).
-In this case, the target is no longer in "gdb mode" -- for example,
-console messages no longer get sent separately to the KGDB port, or
-encapsulated for GDB. If a debug event (e.g. NMI) occurs, the target
-will re-enter "gdb mode" and will display this fact on the console; you
-must give a new "target remote" command to gdb.
-
-NOTE: TO AVOID LOSSING CONSOLE MESSAGES IN CASE THE KERNEL CONSOLE AND
-KGDB USING THE SAME PORT, THE TARGET WAITS FOR ANY INPUT CHARACTER ON
-THE KGDB PORT AFTER A DETACH COMMAND. For example, after the detach you
-could start a terminal emulator on the same host port and enter a <cr>;
-however, this program must then be terminated or suspended in order to
-use GBD again if KGDB is re-entered.

+MORE NOTES ON HD-AUDIO DRIVER
+=============================
+ Takashi Iwai <tiwai@suse.de>
+
+
+GENERAL
+-------
+
+HD-audio is the new standard on-board audio component on modern PCs
+after AC97. Although Linux has been supporting HD-audio since long
+time ago, there are often problems with new machines. A part of the
+problem is broken BIOS, and the rest is the driver implementation.
+This document explains the brief trouble-shooting and debugging
+methods for the HD-audio hardware.
+
+The HD-audio component consists of two parts: the controller chip and
+the codec chips on the HD-audio bus. Linux provides a single driver
+for all controllers, snd-hda-intel. Although the driver name contains
+a word of a well-known harware vendor, it's not specific to it but for
+all controller chips by other companies. Since the HD-audio
+controllers are supposed to be compatible, the single snd-hda-driver
+should work in most cases. But, not surprisingly, there are known
+bugs and issues specific to each controller type. The snd-hda-intel
+driver has a bunch of workarounds for these as described below.
+
+A controller may have multiple codecs. Usually you have one audio
+codec and optionally one modem codec. In theory, there might be
+multiple audio codecs, e.g. for analog and digital outputs, and the
+driver might not work properly because of conflict of mixer elements.
+This should be fixed in future if such hardware really exists.
+
+The snd-hda-intel driver has several different codec parsers depending
+on the codec. It has a generic parser as a fallback, but this
+functionality is fairly limited until now. Instead of the generic
+parser, usually the codec-specific parser (coded in patch_*.c) is used
+for the codec-specific implementations. The details about the
+codec-specific problems are explained in the later sections.
+
+If you are interested in the deep debugging of HD-audio, read the
+HD-audio specification at first. The specification is found on
+Intel's web page, for example:
+
+- http://www.intel.com/standards/hdaudio/
+
+
+HD-AUDIO CONTROLLER
+-------------------
+
+DMA-Position Problem
+~~~~~~~~~~~~~~~~~~~~
+The most common problem of the controller is the inaccurate DMA
+pointer reporting. The DMA pointer for playback and capture can be
+read in two ways, either via a LPIB register or via a position-buffer
+map. As default the driver tries to read from the io-mapped
+position-buffer, and falls back to LPIB if the position-buffer appears
+dead. However, this detection isn't perfect on some devices. In such
+a case, you can change the default method via `position_fix` option.
+
+`position_fix=1` means to use LPIB method explicitly.
+`position_fix=2` means to use the position-buffer. 0 is the default
+value, the automatic check and fallback to LPIB as described in the
+above. If you get a problem of repeated sounds, this option might
+help.
+
+In addition to that, every controller is known to be broken regarding
+the wake-up timing. It wakes up a few samples before actually
+processing the data on the buffer. This caused a lot of problems, for
+example, with ALSA dmix or JACK. Since 2.6.27 kernel, the driver puts
+an artificial delay to the wake up timing. This delay is controlled
+via `bdl_pos_adj` option.
+
+When `bdl_pos_adj` is a negative value (as default), it's assigned to
+an appropriate value depending on the controller chip. For Intel
+chips, it'd be 1 while it'd be 32 for others. Usually this works.
+Only in case it doesn't work and you get warning messages, you should
+change this parameter to other values.
+
+
+Codec-Probing Problem
+~~~~~~~~~~~~~~~~~~~~~
+A less often but a more severe problem is the codec probing. When
+BIOS reports the available codec slots wrongly, the driver gets
+confused and tries to access the non-existing codec slot. This often
+results in the total screw-up, and destructs the further communication
+with the codec chips. The symptom appears usually as error messages
+like:
+------------------------------------------------------------------------
+ hda_intel: azx_get_response timeout, switching to polling mode:
+ last cmd=0x12345678
+ hda_intel: azx_get_response timeout, switching to single_cmd mode:
+ last cmd=0x12345678
+------------------------------------------------------------------------
+
+The first line is a warning, and this is usually relatively harmless.
+It means that the codec response isn't notified via an IRQ. The
+driver uses explicit polling method to read the response. It gives
+very slight CPU overhead, but you'd unlikely notice it.
+
+The second line is, however, a fatal error. If this happens, usually
+it means that something is really wrong. Most likely you are
+accessing a non-existing codec slot.
+
+Thus, if the second error message appears, try to narrow the probed
+codec slots via `probe_mask` option. It's a bitmask, and each bit
+corresponds to the codec slot. For example, to probe only the first
+slot, pass `probe_mask=1`. For the first and the third slots, pass
+`probe_mask=5` (where 5 = 1 | 4), and so on.
+
+Since 2.6.29 kernel, the driver has a more robust probing method, so
+this error might happen rarely, though.
+
+
+Interrupt Handling
+~~~~~~~~~~~~~~~~~~
+In rare but some cases, the interrupt isn't properly handled as
+default. You would notice this by the DMA transfer error reported by
+ALSA PCM core, for example. Using MSI might help in such a case.
+Pass `enable_msi=1` option for enabling MSI.
+
+
+HD-AUDIO CODEC
+--------------
+
+Model Option
+~~~~~~~~~~~~
+The most common problem regarding the HD-audio driver is the
+unsupported codec features or the mismatched device configuration.
+Most of codec-specific code has several preset models, either to
+override the BIOS setup or to provide more comprehensive features.
+
+The driver checks PCI SSID and looks through the static configuration
+table until any matching entry is found. If you have a new machine,
+you may see a message like below:
+------------------------------------------------------------------------
+ hda_codec: Unknown model for ALC880, trying auto-probe from BIOS...
+------------------------------------------------------------------------
+Even if you see such a message, DON'T PANIC. Take a deep breath and
+keep your towel. First of all, it's an informational message, no
+warning, no error. This means that the PCI SSID of your device isn't
+listed in the known preset model (white-)list. But, this doesn't mean
+that the driver is broken. Many codec-drivers provide the automatic
+configuration mechanism based on the BIOS setup.
+
+The HD-audio codec has usually "pin" widgets, and BIOS sets the default
+configuration of each pin, which indicates the location, the
+connection type, the jack color, etc. The HD-audio driver can guess
+the right connection judging from these default configuration values.
+However -- some codec-support codes, such as patch_analog.c, don't
+support the automatic probing (yet as of 2.6.28). And, BIOS is often,
+yes, pretty often broken. It sets up wrong values and screws up the
+driver.
+
+The preset model is provided basically to overcome such a situation.
+When the matching preset model is found in the white-list, the driver
+assumes the static configuration of that preset and builds the mixer
+elements and PCM streams based on the static information. Thus, if
+you have a newer machine with a slightly different PCI SSID from the
+existing one, you may have a good chance to re-use the same model.
+You can pass the `model` option to specify the preset model instead of
+PCI SSID look-up.
+
+What `model` option values are available depends on the codec chip.
+Check your codec chip from the codec proc file (see "Codec Proc-File"
+section below). It will show the vendor/product name of your codec
+chip. Then, see Documentation/sound/alsa/HD-Audio-Modelstxt file,
+the section of HD-audio driver. You can find a list of codecs
+and `model` options belonging to each codec. For example, for Realtek
+ALC262 codec chip, pass `model=ultra` for devices that are compatible
+with Samsung Q1 Ultra.
+
+Thus, the first thing you can do for any brand-new, unsupported and
+non-working HD-audio hardware is to check HD-audio codec and several
+different `model` option values. If you have a luck, some of them
+might suit with your device well.
+
+Some codecs such as ALC880 have a special model option `model=test`.
+This configures the driver to provide as many mixer controls as
+possible for every single pin feature except for the unsolicited
+events (and maybe some other specials). Adjust each mixer element and
+try the I/O in the way of trial-and-error until figuring out the whole
+I/O pin mappings.
+
+Note that `model=generic` has a special meaning. It means to use the
+generic parser regardless of the codec. Usually the codec-specific
+parser is much better than the generic parser (as now). Thus this
+option is more about the debugging purpose.
+
+
+Speaker and Headphone Output
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+One of the most frequent (and obvious) bugs with HD-audio is the
+silent output from either or both of a built-in speaker and a
+headphone jack. In general, you should try a headphone output at
+first. A speaker output often requires more additional controls like
+the external amplifier bits. Thus a headphone output has a slightly
+better chance.
+
+Before making a bug report, double-check whether the mixer is set up
+correctly. The recent version of snd-hda-intel driver provides mostly
+"Master" volume control as well as "Front" volume (where Front
+indicates the front-channels). In addition, there can be individual
+"Headphone" and "Speaker" controls.
+
+Ditto for the speaker output. There can be "External Amplifier"
+switch on some codecs. Turn on this if present.
+
+Another related problem is the automatic mute of speaker output by
+headphone plugging. This feature is implemented in most cases, but
+not on every preset model or codec-support code.
+
+In anyway, try a different model option if you have such a problem.
+Some other models may match better and give you more matching
+functionality. If none of the available models works, send a bug
+report. See the bug report section for details.
+
+If you are masochistic enough to debug the driver problem, note the
+following:
+
+- The speaker (and the headphone, too) output often requires the
+ external amplifier. This can be set usually via EAPD verb or a
+ certain GPIO. If the codec pin supports EAPD, you have a better
+ chance via SET_EAPD_BTL verb (0x70c). On others, GPIO pin (mostly
+ it's either GPIO0 or GPIO1) may turn on/off EAPD.
+- Some Realtek codecs require special vendor-specific coefficients to
+ turn on the amplifier. See patch_realtek.c.
+- IDT codecs may have extra power-enable/disable controls on each
+ analog pin. See patch_sigmatel.c.
+- Very rare but some devices don't accept the pin-detection verb until
+ triggered. Issuing GET_PIN_SENSE verb (0xf09) may result in the
+ codec-communication stall. Some examples are found in
+ patch_realtek.c.
+
+
+Capture Problems
+~~~~~~~~~~~~~~~~
+The capture problems are often because of missing setups of mixers.
+Thus, before submitting a bug report, make sure that you set up the
+mixer correctly. For example, both "Capture Volume" and "Capture
+Switch" have to be set properly in addition to the right "Capture
+Source" or "Input Source" selection. Some devices have "Mic Boost"
+volume or switch.
+
+When the PCM device is opened via "default" PCM (without pulse-audio
+plugin), you'll likely have "Digital Capture Volume" control as well.
+This is provided for the extra gain/attenuation of the signal in
+software, especially for the inputs without the hardware volume
+control such as digital microphones. Unless really needed, this
+should be set to exactly 50%, corresponding to 0dB -- neither extra
+gain nor attenuation. When you use "hw" PCM, i.e., a raw access PCM,
+this control will have no influence, though.
+
+It's known that some codecs / devices have fairly bad analog circuits,
+and the recorded sound contains a certain DC-offset. This is no bug
+of the driver.
+
+Most of modern laptops have no analog CD-input connection. Thus, the
+recording from CD input won't work in many cases although the driver
+provides it as the capture source. Use CDDA instead.
+
+The automatic switching of the built-in and external mic per plugging
+is implemented on some codec models but not on every model. Partly
+because of my laziness but mostly lack of testers. Feel free to
+submit the improvement patch to the author.
+
+
+Direct Debugging
+~~~~~~~~~~~~~~~~
+If no model option gives you a better result, and you are a tough guy
+to fight against evil, try debugging via hitting the raw HD-audio
+codec verbs to the device. Some tools are available: hda-emu and
+hda-analyzer. The detailed description is found in the sections
+below. You'd need to enable hwdep for using these tools. See "Kernel
+Configuration" section.
+
+
+OTHER ISSUES
+------------
+
+Kernel Configuration
+~~~~~~~~~~~~~~~~~~~~
+In general, I recommend you to enable the sound debug option,
+`CONFIG_SND_DEBUG=y`, no matter whether you are debugging or not.
+This enables snd_printd() macro and others, and you'll get additional
+kernel messages at probing.
+
+In addition, you can enable `CONFIG_SND_DEBUG_VERBOSE=y`. But this
+will give you far more messages. Thus turn this on only when you are
+sure to want it.
+
+Don't forget to turn on the appropriate `CONFIG_SND_HDA_CODEC_*`
+options. Note that each of them corresponds to the codec chip, not
+the controller chip. Thus, even if lspci shows the Nvidia controller,
+you may need to choose the option for other vendors. If you are
+unsure, just select all yes.
+
+`CONFIG_SND_HDA_HWDEP` is a useful option for debugging the driver.
+When this is enabled, the driver creates hardware-dependent devices
+(one per each codec), and you have a raw access to the device via
+these device files. For example, `hwC0D2` will be created for the
+codec slot #2 of the first card (#0). For debug-tools such as
+hda-verb and hda-analyzer, the hwdep device has to be enabled.
+Thus, it'd be better to turn this on always.
+
+`CONFIG_SND_HDA_RECONFIG` is a new option, and this depends on the
+hwdep option above. When enabled, you'll have some sysfs files under
+the corresponding hwdep directory. See "HD-audio reconfiguration"
+section below.
+
+`CONFIG_SND_HDA_POWER_SAVE` option enables the power-saving feature.
+See "Power-saving" section below.
+
+
+Codec Proc-File
+~~~~~~~~~~~~~~~
+The codec proc-file is a treasure-chest for debugging HD-audio.
+It shows most of useful information of each codec widget.
+
+The proc file is located in /proc/asound/card*/codec#*, one file per
+each codec slot. You can know the codec vendor, product id and
+names, the type of each widget, capabilities and so on.
+This file, however, doesn't show the jack sensing state, so far. This
+is because the jack-sensing might be depending on the trigger state.
+
+This file will be picked up by the debug tools, and also it can be fed
+to the emulator as the primary codec information. See the debug tools
+section below.
+
+This proc file can be also used to check whether the generic parser is
+used. When the generic parser is used, the vendor/product ID name
+will appear as "Realtek ID 0262", instead of "Realtek ALC262".
+
+
+HD-Audio Reconfiguration
+~~~~~~~~~~~~~~~~~~~~~~~~
+This is an experimental feature to allow you re-configure the HD-audio
+codec dynamically without reloading the driver. The following sysfs
+files are available under each codec-hwdep device directory (e.g.
+/sys/class/sound/hwC0D0):
+
+vendor_id::
+ Shows the 32bit codec vendor-id hex number. You can change the
+ vendor-id value by writing to this file.
+subsystem_id::
+ Shows the 32bit codec subsystem-id hex number. You can change the
+ subsystem-id value by writing to this file.
+revision_id::
+ Shows the 32bit codec revision-id hex number. You can change the
+ revision-id value by writing to this file.
+afg::
+ Shows the AFG ID. This is read-only.
+mfg::
+ Shows the MFG ID. This is read-only.
+name::
+ Shows the codec name string. Can be changed by writing to this
+ file.
+modelname::
+ Shows the currently set `model` option. Can be changed by writing
+ to this file.
+init_verbs::
+ The extra verbs to execute at initialization. You can add a verb by
+ writing to this file. Pass tree numbers, nid, verb and parameter.
+hints::
+ Shows hint strings for codec parsers for any use. Right now it's
+ not used.
+reconfig::
+ Triggers the codec re-configuration. When any value is written to
+ this file, the driver re-initialize and parses the codec tree
+ again. All the changes done by the sysfs entries above are taken
+ into account.
+clear::
+ Resets the codec, removes the mixer elements and PCM stuff of the
+ specified codec, and clear all init verbs and hints.
+
+
+Power-Saving
+~~~~~~~~~~~~
+The power-saving is a kind of auto-suspend of the device. When the
+device is inactive for a certain time, the device is automatically
+turned off to save the power. The time to go down is specified via
+`power_save` module option, and this option can be changed dynamically
+via sysfs.
+
+The power-saving won't work when the analog loopback is enabled on
+some codecs. Make sure that you mute all unneeded signal routes when
+you want the power-saving.
+
+The power-saving feature might cause audible click noises at each
+power-down/up depending on the device. Some of them might be
+solvable, but some are hard, I'm afraid. Some distros such as
+openSUSE enables the power-saving feature automatically when the power
+cable is unplugged. Thus, if you hear noises, suspect first the
+power-saving. See /sys/module/snd_hda_intel/parameters/power_save to
+check the current value. If it's non-zero, the feature is turned on.
+
+
+Development Tree
+~~~~~~~~~~~~~~~~
+The latest development codes for HD-audio are found on sound git tree:
+
+- git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git
+
+The master branch or for-next branches can be used as the main
+development branches in general while the HD-audio specific patches
+are committed in topic/hda branch.
+
+If you are using the latest Linus tree, it'd be better to pull the
+above GIT tree onto it. If you are using the older kernels, an easy
+way to try the latest ALSA code is to build from the snapshot
+tarball. There are daily tarballs and the latest snapshot tarball.
+All can be built just like normal alsa-driver release packages, that
+is, installed via the usual spells: configure, make and make
+install(-modules). See INSTALL in the package. The snapshot tarballs
+are found at:
+
+- ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/
+
+
+Sending a Bug Report
+~~~~~~~~~~~~~~~~~~~~
+If any model or module options don't work for your device, it's time
+to send a bug report to the developers. Give the following in your
+bug report:
+
+- Hardware vendor, product and model names
+- Kernel version (and ALSA-driver version if you built externally)
+- `alsa-info.sh` output; run with `--no-upload` option. See the
+ section below about alsa-info
+
+If it's a regression, at best, send alsa-info outputs of both working
+and non-working kernels. This is really helpful because we can
+compare the codec registers directly.
+
+Send a bug report either the followings:
+
+kernel-bugzilla::
+ http://bugme.linux-foundation.org/
+alsa-devel ML::
+ alsa-devel@alsa-project.org
+
+
+DEBUG TOOLS
+-----------
+
+This section describes some tools available for debugging HD-audio
+problems.
+
+alsa-info
+~~~~~~~~~
+The script `alsa-info.sh` is a very useful tool to gather the audio
+device information. You can fetch the latest version from:
+
+- http://www.alsa-project.org/alsa-info.sh
+
+Run this script as root, and it will gather the important information
+such as the module lists, module parameters, proc file contents
+including the codec proc files, mixer outputs and the control
+elements. As default, it will store the information onto a web server
+on alsa-project.org. But, if you send a bug report, it'd be better to
+run with `--no-upload` option, and attach the generated file.
+
+There are some other useful options. See `--help` option output for
+details.
+
+
+hda-verb
+~~~~~~~~
+hda-verb is a tiny program that allows you to access the HD-audio
+codec directly. You can execute a raw HD-audio codec verb with this.
+This program accesses the hwdep device, thus you need to enable the
+kernel config `CONFIG_SND_HDA_HWDEP=y` beforehand.
+
+The hda-verb program takes four arguments: the hwdep device file, the
+widget NID, the verb and the parameter. When you access to the codec
+on the slot 2 of the card 0, pass /dev/snd/hwC0D2 to the first
+argument, typically. (However, the real path name depends on the
+system.)
+
+The second parameter is the widget number-id to access. The third
+parameter can be either a hex/digit number or a string corresponding
+to a verb. Similarly, the last parameter is the value to write, or
+can be a string for the parameter type.
+
+------------------------------------------------------------------------
+ % hda-verb /dev/snd/hwC0D0 0x12 0x701 2
+ nid = 0x12, verb = 0x701, param = 0x2
+ value = 0x0
+
+ % hda-verb /dev/snd/hwC0D0 0x0 PARAMETERS VENDOR_ID
+ nid = 0x0, verb = 0xf00, param = 0x0
+ value = 0x10ec0262
+
+ % hda-verb /dev/snd/hwC0D0 2 set_a 0xb080
+ nid = 0x2, verb = 0x300, param = 0xb080
+ value = 0x0
+------------------------------------------------------------------------
+
+Although you can issue any verbs with this program, the driver state
+won't be always updated. For example, the volume values are usually
+cached in the driver, and thus changing the widget amp value directly
+via hda-verb won't change the mixer value.
+
+The hda-verb program is found in the ftp directory:
+
+- ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/misc/
+
+Also a git repository is available:
+
+- git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/hda-verb.git
+
+See README file in the tarball for more details about hda-verb
+program.
+
+
+hda-analyzer
+~~~~~~~~~~~~
+hda-analyzer provides a graphical interface to access the raw HD-audio
+control, based on pyGTK2 binding. It's a more powerful version of
+hda-verb. The program gives you an easy-to-use GUI stuff for showing
+the widget information and adjusting the amp values, as well as the
+proc-compatible output.
+
+The hda-analyzer is a part of alsa.git repository in
+alsa-project.org:
+
+- http://git.alsa-project.org/?p=alsa.git;a=tree;f=hda-analyzer
+
+
+Codecgraph
+~~~~~~~~~~
+Codecgraph is a utility program to generate a graph and visualizes the
+codec-node connection of a codec chip. It's especially useful when
+you analyze or debug a codec without a proper datasheet. The program
+parses the given codec proc file and converts to SVG via graphiz
+program.
+
+The tarball and GIT trees are found in the web page at:
+
+- http://helllabs.org/codecgraph/
+
+
+hda-emu
+~~~~~~~
+hda-emu is an HD-audio emulator. The main purpose of this program is
+to debug an HD-audio codec without the real hardware. Thus, it
+doesn't emulate the behavior with the real audio I/O, but it just
+dumps the codec register changes and the ALSA-driver internal changes
+at probing and operating the HD-audio driver.
+
+The program requires a codec proc-file to simulate. Get a proc file
+for the target codec beforehand, or pick up an example codec from the
+codec proc collections in the tarball. Then, run the program with the
+proc file, and the hda-emu program will start parsing the codec file
+and simulates the HD-audio driver:
+
+------------------------------------------------------------------------
+ % hda-emu codecs/stac9200-dell-d820-laptop
+ # Parsing..
+ hda_codec: Unknown model for STAC9200, using BIOS defaults
+ hda_codec: pin nid 08 bios pin config 40c003fa
+ ....
+------------------------------------------------------------------------
+
+The program gives you only a very dumb command-line interface. You
+can get a proc-file dump at the current state, get a list of control
+(mixer) elements, set/get the control element value, simulate the PCM
+operation, the jack plugging simulation, etc.
+
+The package is found in:
+
+- ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/misc/
+
+A git repository is available:
+
+- git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/hda-emu.git
+
+See README file in the tarball for more details about hda-emu
+program.

+Overview of the V4L2 driver framework
+=====================================
+
+This text documents the various structures provided by the V4L2 framework and
+their relationships.
+
+
+Introduction
+------------
+
+The V4L2 drivers tend to be very complex due to the complexity of the
+hardware: most devices have multiple ICs, export multiple device nodes in
+/dev, and create also non-V4L2 devices such as DVB, ALSA, FB, I2C and input
+(IR) devices.
+
+Especially the fact that V4L2 drivers have to setup supporting ICs to
+do audio/video muxing/encoding/decoding makes it more complex than most.
+Usually these ICs are connected to the main bridge driver through one or
+more I2C busses, but other busses can also be used. Such devices are
+called 'sub-devices'.
+
+For a long time the framework was limited to the video_device struct for
+creating V4L device nodes and video_buf for handling the video buffers
+(note that this document does not discuss the video_buf framework).
+
+This meant that all drivers had to do the setup of device instances and
+connecting to sub-devices themselves. Some of this is quite complicated
+to do right and many drivers never did do it correctly.
+
+There is also a lot of common code that could never be refactored due to
+the lack of a framework.
+
+So this framework sets up the basic building blocks that all drivers
+need and this same framework should make it much easier to refactor
+common code into utility functions shared by all drivers.
+
+
+Structure of a driver
+---------------------
+
+All drivers have the following structure:
+
+1) A struct for each device instance containing the device state.
+
+2) A way of initializing and commanding sub-devices (if any).
+
+3) Creating V4L2 device nodes (/dev/videoX, /dev/vbiX, /dev/radioX and
+ /dev/vtxX) and keeping track of device-node specific data.
+
+4) Filehandle-specific structs containing per-filehandle data.
+
+This is a rough schematic of how it all relates:
+
+ device instances
+ |
+ +-sub-device instances
+ |
+ \-V4L2 device nodes
+ |
+ \-filehandle instances
+
+
+Structure of the framework
+--------------------------
+
+The framework closely resembles the driver structure: it has a v4l2_device
+struct for the device instance data, a v4l2_subdev struct to refer to
+sub-device instances, the video_device struct stores V4L2 device node data
+and in the future a v4l2_fh struct will keep track of filehandle instances
+(this is not yet implemented).
+
+
+struct v4l2_device
+------------------
+
+Each device instance is represented by a struct v4l2_device (v4l2-device.h).
+Very simple devices can just allocate this struct, but most of the time you
+would embed this struct inside a larger struct.
+
+You must register the device instance:
+
+ v4l2_device_register(struct device *dev, struct v4l2_device *v4l2_dev);
+
+Registration will initialize the v4l2_device struct and link dev->driver_data
+to v4l2_dev. Registration will also set v4l2_dev->name to a value derived from
+dev (driver name followed by the bus_id, to be precise). You may change the
+name after registration if you want.
+
+The first 'dev' argument is normally the struct device pointer of a pci_dev,
+usb_device or platform_device.
+
+You unregister with:
+
+ v4l2_device_unregister(struct v4l2_device *v4l2_dev);
+
+Unregistering will also automatically unregister all subdevs from the device.
+
+Sometimes you need to iterate over all devices registered by a specific
+driver. This is usually the case if multiple device drivers use the same
+hardware. E.g. the ivtvfb driver is a framebuffer driver that uses the ivtv
+hardware. The same is true for alsa drivers for example.
+
+You can iterate over all registered devices as follows:
+
+static int callback(struct device *dev, void *p)
+{
+ struct v4l2_device *v4l2_dev = dev_get_drvdata(dev);
+
+ /* test if this device was inited */
+ if (v4l2_dev == NULL)
+ return 0;
+ ...
+ return 0;
+}
+
+int iterate(void *p)
+{
+ struct device_driver *drv;
+ int err;
+
+ /* Find driver 'ivtv' on the PCI bus.
+ pci_bus_type is a global. For USB busses use usb_bus_type. */
+ drv = driver_find("ivtv", &pci_bus_type);
+ /* iterate over all ivtv device instances */
+ err = driver_for_each_device(drv, NULL, p, callback);
+ put_driver(drv);
+ return err;
+}
+
+Sometimes you need to keep a running counter of the device instance. This is
+commonly used to map a device instance to an index of a module option array.
+
+The recommended approach is as follows:
+
+static atomic_t drv_instance = ATOMIC_INIT(0);
+
+static int __devinit drv_probe(struct pci_dev *dev,
+ const struct pci_device_id *pci_id)
+{
+ ...
+ state->instance = atomic_inc_return(&drv_instance) - 1;
+}
+
+
+struct v4l2_subdev
+------------------
+
+Many drivers need to communicate with sub-devices. These devices can do all
+sort of tasks, but most commonly they handle audio and/or video muxing,
+encoding or decoding. For webcams common sub-devices are sensors and camera
+controllers.
+
+Usually these are I2C devices, but not necessarily. In order to provide the
+driver with a consistent interface to these sub-devices the v4l2_subdev struct
+(v4l2-subdev.h) was created.
+
+Each sub-device driver must have a v4l2_subdev struct. This struct can be
+stand-alone for simple sub-devices or it might be embedded in a larger struct
+if more state information needs to be stored. Usually there is a low-level
+device struct (e.g. i2c_client) that contains the device data as setup
+by the kernel. It is recommended to store that pointer in the private
+data of v4l2_subdev using v4l2_set_subdevdata(). That makes it easy to go
+from a v4l2_subdev to the actual low-level bus-specific device data.
+
+You also need a way to go from the low-level struct to v4l2_subdev. For the
+common i2c_client struct the i2c_set_clientdata() call is used to store a
+v4l2_subdev pointer, for other busses you may have to use other methods.
+
+From the bridge driver perspective you load the sub-device module and somehow
+obtain the v4l2_subdev pointer. For i2c devices this is easy: you call
+i2c_get_clientdata(). For other busses something similar needs to be done.
+Helper functions exists for sub-devices on an I2C bus that do most of this
+tricky work for you.
+
+Each v4l2_subdev contains function pointers that sub-device drivers can
+implement (or leave NULL if it is not applicable). Since sub-devices can do
+so many different things and you do not want to end up with a huge ops struct
+of which only a handful of ops are commonly implemented, the function pointers
+are sorted according to category and each category has its own ops struct.
+
+The top-level ops struct contains pointers to the category ops structs, which
+may be NULL if the subdev driver does not support anything from that category.
+
+It looks like this:
+
+struct v4l2_subdev_core_ops {
+ int (*g_chip_ident)(struct v4l2_subdev *sd, struct v4l2_chip_ident *chip);
+ int (*log_status)(struct v4l2_subdev *sd);
+ int (*init)(struct v4l2_subdev *sd, u32 val);
+ ...
+};
+
+struct v4l2_subdev_tuner_ops {
+ ...
+};
+
+struct v4l2_subdev_audio_ops {
+ ...
+};
+
+struct v4l2_subdev_video_ops {
+ ...
+};
+
+struct v4l2_subdev_ops {
+ const struct v4l2_subdev_core_ops *core;
+ const struct v4l2_subdev_tuner_ops *tuner;
+ const struct v4l2_subdev_audio_ops *audio;
+ const struct v4l2_subdev_video_ops *video;
+};
+
+The core ops are common to all subdevs, the other categories are implemented
+depending on the sub-device. E.g. a video device is unlikely to support the
+audio ops and vice versa.
+
+This setup limits the number of function pointers while still making it easy
+to add new ops and categories.
+
+A sub-device driver initializes the v4l2_subdev struct using:
+
+ v4l2_subdev_init(subdev, &ops);
+
+Afterwards you need to initialize subdev->name with a unique name and set the
+module owner. This is done for you if you use the i2c helper functions.
+
+A device (bridge) driver needs to register the v4l2_subdev with the
+v4l2_device:
+
+ int err = v4l2_device_register_subdev(device, subdev);
+
+This can fail if the subdev module disappeared before it could be registered.
+After this function was called successfully the subdev->dev field points to
+the v4l2_device.
+
+You can unregister a sub-device using:
+
+ v4l2_device_unregister_subdev(subdev);
+
+Afterwards the subdev module can be unloaded and subdev->dev == NULL.
+
+You can call an ops function either directly:
+
+ err = subdev->ops->core->g_chip_ident(subdev, &chip);
+
+but it is better and easier to use this macro:
+
+ err = v4l2_subdev_call(subdev, core, g_chip_ident, &chip);
+
+The macro will to the right NULL pointer checks and returns -ENODEV if subdev
+is NULL, -ENOIOCTLCMD if either subdev->core or subdev->core->g_chip_ident is
+NULL, or the actual result of the subdev->ops->core->g_chip_ident ops.
+
+It is also possible to call all or a subset of the sub-devices:
+
+ v4l2_device_call_all(dev, 0, core, g_chip_ident, &chip);
+
+Any subdev that does not support this ops is skipped and error results are
+ignored. If you want to check for errors use this:
+
+ err = v4l2_device_call_until_err(dev, 0, core, g_chip_ident, &chip);
+
+Any error except -ENOIOCTLCMD will exit the loop with that error. If no
+errors (except -ENOIOCTLCMD) occured, then 0 is returned.
+
+The second argument to both calls is a group ID. If 0, then all subdevs are
+called. If non-zero, then only those whose group ID match that value will
+be called. Before a bridge driver registers a subdev it can set subdev->grp_id
+to whatever value it wants (it's 0 by default). This value is owned by the
+bridge driver and the sub-device driver will never modify or use it.
+
+The group ID gives the bridge driver more control how callbacks are called.
+For example, there may be multiple audio chips on a board, each capable of
+changing the volume. But usually only one will actually be used when the
+user want to change the volume. You can set the group ID for that subdev to
+e.g. AUDIO_CONTROLLER and specify that as the group ID value when calling
+v4l2_device_call_all(). That ensures that it will only go to the subdev
+that needs it.
+
+The advantage of using v4l2_subdev is that it is a generic struct and does
+not contain any knowledge about the underlying hardware. So a driver might
+contain several subdevs that use an I2C bus, but also a subdev that is
+controlled through GPIO pins. This distinction is only relevant when setting
+up the device, but once the subdev is registered it is completely transparent.
+
+
+I2C sub-device drivers
+----------------------
+
+Since these drivers are so common, special helper functions are available to
+ease the use of these drivers (v4l2-common.h).
+
+The recommended method of adding v4l2_subdev support to an I2C driver is to
+embed the v4l2_subdev struct into the state struct that is created for each
+I2C device instance. Very simple devices have no state struct and in that case
+you can just create a v4l2_subdev directly.
+
+A typical state struct would look like this (where 'chipname' is replaced by
+the name of the chip):
+
+struct chipname_state {
+ struct v4l2_subdev sd;
+ ... /* additional state fields */
+};
+
+Initialize the v4l2_subdev struct as follows:
+
+ v4l2_i2c_subdev_init(&state->sd, client, subdev_ops);
+
+This function will fill in all the fields of v4l2_subdev and ensure that the
+v4l2_subdev and i2c_client both point to one another.
+
+You should also add a helper inline function to go from a v4l2_subdev pointer
+to a chipname_state struct:
+
+static inline struct chipname_state *to_state(struct v4l2_subdev *sd)
+{
+ return container_of(sd, struct chipname_state, sd);
+}
+
+Use this to go from the v4l2_subdev struct to the i2c_client struct:
+
+ struct i2c_client *client = v4l2_get_subdevdata(sd);
+
+And this to go from an i2c_client to a v4l2_subdev struct:
+
+ struct v4l2_subdev *sd = i2c_get_clientdata(client);
+
+Finally you need to make a command function to make driver->command()
+call the right subdev_ops functions:
+
+static int subdev_command(struct i2c_client *client, unsigned cmd, void *arg)
+{
+ return v4l2_subdev_command(i2c_get_clientdata(client), cmd, arg);
+}
+
+If driver->command is never used then you can leave this out. Eventually the
+driver->command usage should be removed from v4l.
+
+Make sure to call v4l2_device_unregister_subdev(sd) when the remove() callback
+is called. This will unregister the sub-device from the bridge driver. It is
+safe to call this even if the sub-device was never registered.
+
+
+The bridge driver also has some helper functions it can use:
+
+struct v4l2_subdev *sd = v4l2_i2c_new_subdev(adapter, "module_foo", "chipid", 0x36);
+
+This loads the given module (can be NULL if no module needs to be loaded) and
+calls i2c_new_device() with the given i2c_adapter and chip/address arguments.
+If all goes well, then it registers the subdev with the v4l2_device. It gets
+the v4l2_device by calling i2c_get_adapdata(adapter), so you should make sure
+that adapdata is set to v4l2_device when you setup the i2c_adapter in your
+driver.
+
+You can also use v4l2_i2c_new_probed_subdev() which is very similar to
+v4l2_i2c_new_subdev(), except that it has an array of possible I2C addresses
+that it should probe. Internally it calls i2c_new_probed_device().
+
+Both functions return NULL if something went wrong.
+
+
+struct video_device
+-------------------
+
+The actual device nodes in the /dev directory are created using the
+video_device struct (v4l2-dev.h). This struct can either be allocated
+dynamically or embedded in a larger struct.
+
+To allocate it dynamically use:
+
+ struct video_device *vdev = video_device_alloc();
+
+ if (vdev == NULL)
+ return -ENOMEM;
+
+ vdev->release = video_device_release;
+
+If you embed it in a larger struct, then you must set the release()
+callback to your own function:
+
+ struct video_device *vdev = &my_vdev->vdev;
+
+ vdev->release = my_vdev_release;
+
+The release callback must be set and it is called when the last user
+of the video device exits.
+
+The default video_device_release() callback just calls kfree to free the
+allocated memory.
+
+You should also set these fields:
+
+- parent: set to the parent device (same device as was used to register
+ v4l2_device).
+- name: set to something descriptive and unique.
+- fops: set to the file_operations struct.
+- ioctl_ops: if you use the v4l2_ioctl_ops to simplify ioctl maintenance
+ (highly recommended to use this and it might become compulsory in the
+ future!), then set this to your v4l2_ioctl_ops struct.
+
+If you use v4l2_ioctl_ops, then you should set .unlocked_ioctl to
+__video_ioctl2 or .ioctl to video_ioctl2 in your file_operations struct.
+
+
+video_device registration
+-------------------------
+
+Next you register the video device: this will create the character device
+for you.
+
+ err = video_register_device(vdev, VFL_TYPE_GRABBER, -1);
+ if (err) {
+ video_device_release(vdev); // or kfree(my_vdev);
+ return err;
+ }
+
+Which device is registered depends on the type argument. The following
+types exist:
+
+VFL_TYPE_GRABBER: videoX for video input/output devices
+VFL_TYPE_VBI: vbiX for vertical blank data (i.e. closed captions, teletext)
+VFL_TYPE_RADIO: radioX for radio tuners
+VFL_TYPE_VTX: vtxX for teletext devices (deprecated, don't use)
+
+The last argument gives you a certain amount of control over the device
+kernel number used (i.e. the X in videoX). Normally you will pass -1 to
+let the v4l2 framework pick the first free number. But if a driver creates
+many devices, then it can be useful to have different video devices in
+separate ranges. For example, video capture devices start at 0, video
+output devices start at 16.
+
+So you can use the last argument to specify a minimum kernel number and
+the v4l2 framework will try to pick the first free number that is equal
+or higher to what you passed. If that fails, then it will just pick the
+first free number.
+
+Whenever a device node is created some attributes are also created for you.
+If you look in /sys/class/video4linux you see the devices. Go into e.g.
+video0 and you will see 'name' and 'index' attributes. The 'name' attribute
+is the 'name' field of the video_device struct. The 'index' attribute is
+a device node index that can be assigned by the driver, or that is calculated
+for you.
+
+If you call video_register_device(), then the index is just increased by
+1 for each device node you register. The first video device node you register
+always starts off with 0.
+
+Alternatively you can call video_register_device_index() which is identical
+to video_register_device(), but with an extra index argument. Here you can
+pass a specific index value (between 0 and 31) that should be used.
+
+Users can setup udev rules that utilize the index attribute to make fancy
+device names (e.g. 'mpegX' for MPEG video capture device nodes).
+
+After the device was successfully registered, then you can use these fields:
+
+- vfl_type: the device type passed to video_register_device.
+- minor: the assigned device minor number.
+- num: the device kernel number (i.e. the X in videoX).
+- index: the device index number (calculated or set explicitly using
+ video_register_device_index).
+
+If the registration failed, then you need to call video_device_release()
+to free the allocated video_device struct, or free your own struct if the
+video_device was embedded in it. The vdev->release() callback will never
+be called if the registration failed, nor should you ever attempt to
+unregister the device if the registration failed.
+
+
+video_device cleanup
+--------------------
+
+When the video device nodes have to be removed, either during the unload
+of the driver or because the USB device was disconnected, then you should
+unregister them:
+
+ video_unregister_device(vdev);
+
+This will remove the device nodes from sysfs (causing udev to remove them
+from /dev).
+
+After video_unregister_device() returns no new opens can be done.
+
+However, in the case of USB devices some application might still have one
+of these device nodes open. You should block all new accesses to read,
+write, poll, etc. except possibly for certain ioctl operations like
+queueing buffers.
+
+When the last user of the video device node exits, then the vdev->release()
+callback is called and you can do the final cleanup there.
+
+
+video_device helper functions
+-----------------------------
+
+There are a few useful helper functions:
+
+You can set/get driver private data in the video_device struct using:
+
+void *video_get_drvdata(struct video_device *dev);
+void video_set_drvdata(struct video_device *dev, void *data);
+
+Note that you can safely call video_set_drvdata() before calling
+video_register_device().
+
+And this function:
+
+struct video_device *video_devdata(struct file *file);
+
+returns the video_device belonging to the file struct.
+
+The final helper function combines video_get_drvdata with
+video_devdata:
+
+void *video_drvdata(struct file *file);
+
+You can go from a video_device struct to the v4l2_device struct using:
+
+struct v4l2_device *v4l2_dev = dev_get_drvdata(vdev->parent);

+Advanced APIs for drivers
+-------------------------
+A. Exporting pages to users with remap_pfn_range, io_remap_pfn_range,
+vm_insert_pfn
+
+Drivers wanting to export some pages to userspace do it by using mmap
+interface and a combination of
+1) pgprot_noncached()
+2) io_remap_pfn_range() or remap_pfn_range() or vm_insert_pfn()
+
+With PAT support, a new API pgprot_writecombine is being added. So, drivers can
+continue to use the above sequence, with either pgprot_noncached() or
+pgprot_writecombine() in step 1, followed by step 2.
+
+In addition, step 2 internally tracks the region as UC or WC in memtype
+list in order to ensure no conflicting mapping.
+
+Note that this set of APIs only works with IO (non RAM) regions. If driver
+wants to export a RAM region, it has to do set_memory_uc() or set_memory_wc()
+as step 0 above and also track the usage of those pages and use set_memory_wb()
+before the page is freed to free pool.
+
+
+
Notes:
-- in the above table mean "Not suggested usage for the API". Some of the --'s

- This option changes the kernel logical page size to 64k. On machines

- while on hardware with such support, it will be used to map

+ Select the kernel logical page size. Increasing the page size
+ will reduce software overhead at each page boundary, allow

+
+ Some dedicated systems, such as software raid serving with

+/*
+ * This is the device driver for the MPC5200 interrupt controller.
+ *
+ * hardware overview
+ * -----------------
+ * The MPC5200 interrupt controller groups the all interrupt sources into
+ * three groups called 'critical', 'main', and 'peripheral'. The critical
+ * group has 3 irqs, External IRQ0, slice timer 0 irq, and wake from deep
+ * sleep. Main group include the other 3 external IRQs, slice timer 1, RTC,
+ * gpios, and the general purpose timers. Peripheral group contains the
+ * remaining irq sources from all of the on-chip peripherals (PSCs, Ethernet,
+ * USB, DMA, etc).
+ *
+ * virqs
+ * -----
+ * The Linux IRQ subsystem requires that each irq source be assigned a
+ * system wide unique IRQ number starting at 1 (0 means no irq). Since
+ * systems can have multiple interrupt controllers, the virtual IRQ (virq)
+ * infrastructure lets each interrupt controller to define a local set
+ * of IRQ numbers and the virq infrastructure maps those numbers into
+ * a unique range of the global IRQ# space.
+ *
+ * To define a range of virq numbers for this controller, this driver first
+ * assigns a number to each of the irq groups (called the level 1 or L1
+ * value). Within each group individual irq sources are also assigned a
+ * number, as defined by the MPC5200 user guide, and refers to it as the
+ * level 2 or L2 value. The virq number is determined by shifting up the
+ * L1 value by MPC52xx_IRQ_L1_OFFSET and ORing it with the L2 value.
+ *
+ * For example, the TMR0 interrupt is irq 9 in the main group. The
+ * virq for TMR0 is calculated by ((1 << MPC52xx_IRQ_L1_OFFSET) | 9).
+ *
+ * The observant reader will also notice that this driver defines a 4th
+ * interrupt group called 'bestcomm'. The bestcomm group isn't physically
+ * part of the MPC5200 interrupt controller, but it is used here to assign
+ * a separate virq number for each bestcomm task (since any of the 16
+ * bestcomm tasks can cause the bestcomm interrupt to be raised). When a
+ * bestcomm interrupt occurs (peripheral group, irq 0) this driver determines
+ * which task needs servicing and returns the irq number for that task. This
+ * allows drivers which use bestcomm to define their own interrupt handlers.
+ *
+ * irq_chip structures
+ * -------------------
+ * For actually manipulating IRQs (masking, enabling, clearing, etc) this
+ * driver defines four separate 'irq_chip' structures, one for the main
+ * group, one for the peripherals group, one for the bestcomm group and one
+ * for external interrupts. The irq_chip structures provide the hooks needed
+ * to manipulate each IRQ source, and since each group is has a separate set
+ * of registers for controlling the irq, it makes sense to divide up the
+ * hooks along those lines.
+ *
+ * You'll notice that there is not an irq_chip for the critical group and
+ * you'll also notice that there is an irq_chip defined for external
+ * interrupts even though there is no external interrupt group. The reason
+ * for this is that the four external interrupts are all managed with the same
+ * register even though one of the external IRQs is in the critical group and
+ * the other three are in the main group. For this reason it makes sense for
+ * the 4 external irqs to be managed using a separate set of hooks. The
+ * reason there is no crit irq_chip is that of the 3 irqs in the critical
+ * group, only external interrupt is actually support at this time by this
+ * driver and since external interrupt is the only one used, it can just
+ * be directed to make use of the external irq irq_chip.
+ *
+ * device tree bindings
+ * --------------------
+ * The device tree bindings for this controller reflect the two level
+ * organization of irqs in the device. #interrupt-cells = <3> where the
+ * first cell is the group number [0..3], the second cell is the irq
+ * number in the group, and the third cell is the sense type (level/edge).
+ * For reference, the following is a list of the interrupt property values
+ * associated with external interrupt sources on the MPC5200 (just because
+ * it is non-obvious to determine what the interrupts property should be
+ * when reading the mpc5200 manual and it is a frequently asked question).
+ *
+ * External interrupts:
+ * <0 0 n> external irq0, n is sense (n=0: level high,
+ * <1 1 n> external irq1, n is sense n=1: edge rising,
+ * <1 2 n> external irq2, n is sense n=2: edge falling,
+ * <1 3 n> external irq3, n is sense n=3: level low)

- * This implements a small wrapper set to make code using the old ISA DMA API
- * work with the SH DMA API. Since most of the work in the new API happens
- * at ops->xfer() time, we simply use the various set_dma_xxx() routines to
- * fill in per-channel info, and then hand hand this off to ops->xfer() at
- * enable_dma() time.
- *
- * For channels that are doing on-demand data transfer via cascading, the
- * channel itself will still need to be configured through the new API. As
- * such, this code is meant for only the simplest of tasks (and shouldn't be
- * used in any new drivers at all).
- *
- * NOTE: ops->xfer() is the preferred way of doing things. However, there
- * are some users of the ISA DMA API that exist in common code that we
- * don't necessarily want to go out of our way to break, so we still
- * allow for some compatibility at that level. Any new code is strongly
- * advised to run far away from the ISA DMA API and use the SH DMA API
- * directly.

- * A breakpoint also needs to be generated to begin communication. This

- * In this case, set_debug_traps() is not used to "take over" exceptions;
- * other kernel code is modified instead to enter the kgdb functions here
- * when appropriate (see entry.S for breakpoint traps and NMI interrupts,
- * see traps.c for kernel error exceptions).
- *
- * The following gdb commands are supported:
- *
- * Command Function Return value
- *
- * g return the value of the CPU registers hex data or ENN
- * G set the value of the CPU registers OK or ENN
- *
- * mAA..AA,LLLL Read LLLL bytes at address AA..AA hex data or ENN
- * MAA..AA,LLLL: Write LLLL bytes at address AA.AA OK or ENN
- * XAA..AA,LLLL: Same, but data is binary (not hex) OK or ENN
- *
- * c Resume at current address SNN ( signal NN)
- * cAA..AA Continue at address AA..AA SNN
- * CNN; Resume at current address with signal SNN
- * CNN;AA..AA Resume at address AA..AA with signal SNN
- *
- * s Step one instruction SNN
- * sAA..AA Step one instruction from AA..AA SNN
- * SNN; Step one instruction with signal SNN
- * SNNAA..AA Step one instruction from AA..AA w/NN SNN
- *
- * k kill (Detach GDB)
- *
- * d Toggle debug flag
- * D Detach GDB
- *
- * Hct Set thread t for operations, OK or ENN
- * c = 'c' (step, cont), c = 'g' (other
- * operations)
- *
- * qC Query current thread ID QCpid
- * qfThreadInfo Get list of current threads (first) m<id>
- * qsThreadInfo " " " " " (subsequent)
- * qOffsets Get section offsets Text=x;Data=y;Bss=z
- *
- * TXX Find if thread XX is alive OK or ENN
- * ? What was the last sigval ? SNN (signal NN)
- * O Output to GDB console
- *
- * Remote communication protocol.
- *
- * A debug packet whose contents are <data> is encapsulated for
- * transmission in the form:
- *
- * $ <data> # CSUM1 CSUM2
- *
- * <data> must be ASCII alphanumeric and cannot include characters
- * '$' or '#'. If <data> starts with two characters followed by
- * ':', then the existing stubs interpret this as a sequence number.
- *
- * CSUM1 and CSUM2 are ascii hex representation of an 8-bit
- * checksum of <data>, the most significant nibble is sent first.
- * the hex digits 0-9,a-f are used.
- *
- * Receiver responds with:
- *
- * + - if CSUM is correct and ready for next packet
- * - - if CSUM is incorrect
- *
- * Responses can be run-length encoded to save space. A '*' means that
- * the next character is an ASCII encoding giving a repeat count which
- * stands for that many repetitions of the character preceding the '*'.
- * The encoding is n+29, yielding a printable character where n >=3
- * (which is where RLE starts to win). Don't use an n > 126.
- *
- * So "0* " means the same as "0000".

+! SH5 code Copyright 2002 SuperH Ltd.
+!
+! Entry: ARG0: destination pointer
+! ARG1: source pointer
+! ARG2: byte count
+!
+! Exit: RESULT: destination pointer
+! any other registers in the range r0-r7: trashed
+!
+! Notes: Usually one wants to do small reads and write a longword, but
+! unfortunately it is difficult in some cases to concatanate bytes
+! into a longword on the SH, so this does a longword read and small
+! writes.
+!
+! This implementation makes two assumptions about how it is called:
+!
+! 1.: If the byte count is nonzero, the address of the last byte to be
+! copied is unsigned greater than the address of the first byte to
+! be copied. This could be easily swapped for a signed comparison,
+! but the algorithm used needs some comparison.
+!
+! 2.: When there are two or three bytes in the last word of an 11-or-more
+! bytes memory chunk to b copied, the rest of the word can be read
+! without side effects.
+! This could be easily changed by increasing the minumum size of
+! a fast memcpy and the amount subtracted from r7 before L_2l_loop be 2,
+! however, this would cost a few extra cyles on average.
+! For SHmedia, the assumption is that any quadword can be read in its
+! enirety if at least one byte is included in the copy.

- ---help---
- A pseudo terminal (PTY) is a software device consisting of two
- halves: a master and a slave. The slave device behaves identical to
- a physical terminal; the master device is used by a process to
- read data from and write data to the slave, thereby emulating a
- terminal. Typical programs for the master side are telnet servers
- and xterms.
-
- Linux has traditionally used the BSD-like names /dev/ptyxx for
- masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
- has a number of problems. The GNU C library glibc 2.1 and later,
- however, supports the Unix98 naming standard: in order to acquire a
- pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
- terminal is then made available to the process and the pseudo
- terminal slave can be accessed as /dev/pts/<number>. What was
- traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
-
- The entries in /dev/pts/ are created on the fly by a virtual
- file system; therefore, if you say Y here you should say Y to

- This kernel feature is useful for number crunching applications
- that may need to compute untrusted bytecode during their
- execution. By using pipes or other transports made available to
- the process as file descriptors supporting the read/write
- syscalls, it's possible to isolate those applications in

- enabled via /proc/<pid>/seccomp, it cannot be disabled
- and the task is only allowed to execute a few safe syscalls
- defined by each seccomp mode.

+ * Presumably, when dda3 is added in, it gets to adjust the dda2_inc value

+ * dda1_inc = floor (dda1_ideal)
+ * dda2 = dda1_ideal - dda1_inc
+ *
+ * then pick a ratio for dda2 that gives the closest approximation. If
+ * you can't get close enough, you can play with dda3 as well. This
+ * seems likely to happen when dda2 is small as the jumps would be larger

-/* Driver for Bt832 CMOS Camera Video Processor
- i2c-addresses: 0x88 or 0x8a
-
- The BT832 interfaces to a Quartzsight Digital Camera (352x288, 25 or 30 fps)
- via a 9 pin connector ( 4-wire SDATA, 2-wire i2c, SCLK, VCC, GND).
- It outputs an 8-bit 4:2:2 YUV or YCrCb video signal which can be directly
- connected to bt848/bt878 GPIO pins on this purpose.
- (see: VLSI Vision Ltd. www.vvl.co.uk for camera datasheets)
-
- Supported Cards:
- - Pixelview Rev.4E: 0x8a
- GPIO 0x400000 toggles Bt832 RESET, and the chip changes to i2c 0x88 !
-
- (c) Gunther Mayer, 2002
-
- STATUS:
- - detect chip and hexdump
- - reset chip and leave low power mode
- - detect camera present
-
- TODO:
- - make it work (find correct setup for Bt832 and Bt878)

- Video Sampling
-Digital video is a sampled form of analog video. The most common sampling schemes in use today are:
- Pixel Clock Horiz Horiz Vert
- Rate Total Active
-NTSC square pixel 12.27 MHz 780 640 525
-NTSC CCIR-601 13.5 MHz 858 720 525
-NTSC 4FSc 14.32 MHz 910 768 525
-PAL square pixel 14.75 MHz 944 768 625
-PAL CCIR-601 13.5 MHz 864 720 625
-PAL 4FSc 17.72 MHz 1135 948 625
-
-For the CCIR-601 standards, the sampling is based on a static orthogonal sampling grid. The luminance component (Y) is sampled at 13.5 MHz, while the two color difference signals, Cr and Cb are sampled at half that, or 6.75 MHz. The Cr and Cb samples are colocated with alternate Y samples, and they are taken at the same position on each line, such that one sample is coincident with the 50% point of the falling edge of analog sync. The samples are coded to either 8 or 10 bits per component.

- Theory of Operation
-
-I. Board Compatibility
-
-This device driver is designed for the Intel i82557 "Speedo3" chip, Intel's
-single-chip fast Ethernet controller for PCI, as used on the Intel
-EtherExpress Pro 100 adapter.
-
-II. Board-specific settings
-
-PCI bus devices are configured by the system at boot time, so no jumpers
-need to be set on the board. The system BIOS should be set to assign the
-PCI INTA signal to an otherwise unused system IRQ line. While it's
-possible to share PCI interrupt lines, it negatively impacts performance and
-only recent kernels support it.
-
-III. Driver operation
-
-IIIA. General
-The Speedo3 is very similar to other Intel network chips, that is to say
-"apparently designed on a different planet". This chips retains the complex
-Rx and Tx descriptors and multiple buffers pointers as previous chips, but
-also has simplified Tx and Rx buffer modes. This driver uses the "flexible"
-Tx mode, but in a simplified lower-overhead manner: it associates only a
-single buffer descriptor with each frame descriptor.
-
-Despite the extra space overhead in each receive skbuff, the driver must use
-the simplified Rx buffer mode to assure that only a single data buffer is
-associated with each RxFD. The driver implements this by reserving space
-for the Rx descriptor at the head of each Rx skbuff.
-
-The Speedo-3 has receive and command unit base addresses that are added to
-almost all descriptor pointers. The driver sets these to zero, so that all
-pointer fields are absolute addresses.
-
-The System Control Block (SCB) of some previous Intel chips exists on the
-chip in both PCI I/O and memory space. This driver uses the I/O space
-registers, but might switch to memory mapped mode to better support non-x86
-processors.
-
-IIIB. Transmit structure
-
-The driver must use the complex Tx command+descriptor mode in order to
-have a indirect pointer to the skbuff data section. Each Tx command block
-(TxCB) is associated with two immediately appended Tx Buffer Descriptor
-(TxBD). A fixed ring of these TxCB+TxBD pairs are kept as part of the
-speedo_private data structure for each adapter instance.
-
-The newer i82558 explicitly supports this structure, and can read the two
-TxBDs in the same PCI burst as the TxCB.
-
-This ring structure is used for all normal transmit packets, but the
-transmit packet descriptors aren't long enough for most non-Tx commands such
-as CmdConfigure. This is complicated by the possibility that the chip has
-already loaded the link address in the previous descriptor. So for these
-commands we convert the next free descriptor on the ring to a NoOp, and point
-that descriptor's link to the complex command.
-
-An additional complexity of these non-transmit commands are that they may be
-added asynchronous to the normal transmit queue, so we disable interrupts
-whenever the Tx descriptor ring is manipulated.
-
-A notable aspect of these special configure commands is that they do
-work with the normal Tx ring entry scavenge method. The Tx ring scavenge
-is done at interrupt time using the 'dirty_tx' index, and checking for the
-command-complete bit. While the setup frames may have the NoOp command on the
-Tx ring marked as complete, but not have completed the setup command, this
-is not a problem. The tx_ring entry can be still safely reused, as the
-tx_skbuff[] entry is always empty for config_cmd and mc_setup frames.
-
-Commands may have bits set e.g. CmdSuspend in the command word to either
-suspend or stop the transmit/command unit. This driver always flags the last
-command with CmdSuspend, erases the CmdSuspend in the previous command, and
-then issues a CU_RESUME.
-Note: Watch out for the potential race condition here: imagine
- erasing the previous suspend
- the chip processes the previous command
- the chip processes the final command, and suspends
- doing the CU_RESUME
- the chip processes the next-yet-valid post-final-command.
-So blindly sending a CU_RESUME is only safe if we do it immediately after
-after erasing the previous CmdSuspend, without the possibility of an
-intervening delay. Thus the resume command is always within the
-interrupts-disabled region. This is a timing dependence, but handling this
-condition in a timing-independent way would considerably complicate the code.
-
-Note: In previous generation Intel chips, restarting the command unit was a
-notoriously slow process. This is presumably no longer true.
-
-IIIC. Receive structure
-
-Because of the bus-master support on the Speedo3 this driver uses the new
-SKBUFF_RX_COPYBREAK scheme, rather than a fixed intermediate receive buffer.
-This scheme allocates full-sized skbuffs as receive buffers. The value
-SKBUFF_RX_COPYBREAK is used as the copying breakpoint: it is chosen to
-trade-off the memory wasted by passing the full-sized skbuff to the queue
-layer for all frames vs. the copying cost of copying a frame to a
-correctly-sized skbuff.
-
-For small frames the copying cost is negligible (esp. considering that we
-are pre-loading the cache with immediately useful header information), so we
-allocate a new, minimally-sized skbuff. For large frames the copying cost
-is non-trivial, and the larger copy might flush the cache of useful data, so
-we pass up the skbuff the packet was received into.
-
-IV. Notes
-
-Thanks to Steve Williams of Intel for arranging the non-disclosure agreement
-that stated that I could disclose the information. But I still resent
-having to sign an Intel NDA when I'm helping Intel sell their own product!

-
- See <file:Documentation/networking/README.ipw2100> for information on

-
- In order to use this driver, you will need a firmware image for it.
- You can obtain the firmware from

- will need to place it in /lib/firmware.
-
- You will also very likely need the Wireless Tools in order to

-
- It is recommended that you compile this driver as a module (M)

- * Interface definitions for transmit rate control modules for the
- * Atheros driver.
- *
- * A rate control module is responsible for choosing the transmit rate
- * for each data frame. Management+control frames are always sent at
- * a fixed rate.
- *
- * Only one module may be present at a time; the driver references
- * rate control interfaces by symbol name. If multiple modules are
- * to be supported we'll need to switch to a registration-based scheme
- * as is currently done, for example, for authentication modules.
- *
- * An instance of the rate control module is attached to each device
- * at attach time and detached when the device is destroyed. The module
- * may associate data with each device and each node (station). Both
- * sets of storage are opaque except for the size of the per-node storage
- * which must be provided when the module is attached.
- *
- * The rate control module is notified for each state transition and
- * station association/reassociation. Otherwise it is queried for a
- * rate for each outgoing frame and provided status from each transmitted
- * frame. Any ancillary processing is the responsibility of the module
- * (e.g. if periodic processing is required then the module should setup
- * it's own timer).
- *
- * In addition to the transmit rate for each frame the module must also
- * indicate the number of attempts to make at the specified rate. If this
- * number is != ATH_TXMAXTRY then an additional callback is made to setup
- * additional transmit state. The rate control code is assumed to write
- * this additional data directly to the transmit descriptor.

+ % tethereal -i rtap0
+
+ If you do not specify 'rtap_iface=1' as a module parameter then

+/*
+ * Internal implementation notes.
+ *
+ * The exchange manager is one by default in libfc but LLD may choose
+ * to have one per CPU. The sequence manager is one per exchange manager
+ * and currently never separated.
+ *
+ * Section 9.8 in FC-FS-2 specifies: "The SEQ_ID is a one-byte field
+ * assigned by the Sequence Initiator that shall be unique for a specific
+ * D_ID and S_ID pair while the Sequence is open." Note that it isn't
+ * qualified by exchange ID, which one might think it would be.
+ * In practice this limits the number of open sequences and exchanges to 256
+ * per session. For most targets we could treat this limit as per exchange.
+ *
+ * The exchange and its sequence are freed when the last sequence is received.
+ * It's possible for the remote port to leave an exchange open without
+ * sending any sequences.
+ *
+ * Notes on reference counts:
+ *
+ * Exchanges are reference counted and exchange gets freed when the reference
+ * count becomes zero.
+ *
+ * Timeouts:
+ * Sequences are timed out for E_D_TOV and R_A_TOV.
+ *
+ * Sequence event handling:
+ *
+ * The following events may occur on initiator sequences:
+ *
+ * Send.
+ * For now, the whole thing is sent.
+ * Receive ACK
+ * This applies only to class F.
+ * The sequence is marked complete.
+ * ULP completion.
+ * The upper layer calls fc_exch_done() when done
+ * with exchange and sequence tuple.
+ * RX-inferred completion.
+ * When we receive the next sequence on the same exchange, we can
+ * retire the previous sequence ID. (XXX not implemented).
+ * Timeout.
+ * R_A_TOV frees the sequence ID. If we're waiting for ACK,
+ * E_D_TOV causes abort and calls upper layer response handler
+ * with FC_EX_TIMEOUT error.
+ * Receive RJT
+ * XXX defer.
+ * Send ABTS
+ * On timeout.
+ *
+ * The following events may occur on recipient sequences:
+ *
+ * Receive
+ * Allocate sequence for first frame received.
+ * Hold during receive handler.
+ * Release when final frame received.
+ * Keep status of last N of these for the ELS RES command. XXX TBD.
+ * Receive ABTS
+ * Deallocate sequence
+ * Send RJT
+ * Deallocate
+ *
+ * For now, we neglect conditions where only part of a sequence was
+ * received or transmitted, or where out-of-order receipt is detected.
+ */
+
+/*
+ * Locking notes:
+ *
+ * The EM code run in a per-CPU worker thread.
+ *
+ * To protect against concurrency between a worker thread code and timers,
+ * sequence allocation and deallocation must be locked.
+ * - exchange refcnt can be done atomicly without locks.
+ * - sequence allocation must be locked by exch lock.
+ * - If the em_lock and ex_lock must be taken at the same time, then the

+/*
+ * PORT LOCKING NOTES
+ *
+ * These comments only apply to the 'port code' which consists of the lport,
+ * disc and rport blocks.
+ *
+ * MOTIVATION
+ *
+ * The lport, disc and rport blocks all have mutexes that are used to protect
+ * those objects. The main motivation for these locks is to prevent from
+ * having an lport reset just before we send a frame. In that scenario the
+ * lport's FID would get set to zero and then we'd send a frame with an
+ * invalid SID. We also need to ensure that states don't change unexpectedly
+ * while processing another state.
+ *
+ * HEIRARCHY
+ *
+ * The following heirarchy defines the locking rules. A greater lock
+ * may be held before acquiring a lesser lock, but a lesser lock should never
+ * be held while attempting to acquire a greater lock. Here is the heirarchy-
+ *
+ * lport > disc, lport > rport, disc > rport
+ *
+ * CALLBACKS
+ *
+ * The callbacks cause complications with this scheme. There is a callback
+ * from the rport (to either lport or disc) and a callback from disc
+ * (to the lport).
+ *
+ * As rports exit the rport state machine a callback is made to the owner of
+ * the rport to notify success or failure. Since the callback is likely to
+ * cause the lport or disc to grab its lock we cannot hold the rport lock
+ * while making the callback. To ensure that the rport is not free'd while
+ * processing the callback the rport callbacks are serialized through a
+ * single-threaded workqueue. An rport would never be free'd while in a
+ * callback handler becuase no other rport work in this queue can be executed
+ * at the same time.
+ *
+ * When discovery succeeds or fails a callback is made to the lport as
+ * notification. Currently, succesful discovery causes the lport to take no
+ * action. A failure will cause the lport to reset. There is likely a circular
+ * locking problem with this implementation.
+ */
+
+/*
+ * LPORT LOCKING
+ *
+ * The critical sections protected by the lport's mutex are quite broad and
+ * may be improved upon in the future. The lport code and its locking doesn't
+ * influence the I/O path, so excessive locking doesn't penalize I/O
+ * performance.
+ *
+ * The strategy is to lock whenever processing a request or response. Note
+ * that every _enter_* function corresponds to a state change. They generally
+ * change the lports state and then send a request out on the wire. We lock
+ * before calling any of these functions to protect that state change. This
+ * means that the entry points into the lport block manage the locks while
+ * the state machine can transition between states (i.e. _enter_* functions)
+ * while always staying protected.
+ *

+ * RPORT GENERAL INFO
+ *
+ * This file contains all processing regarding fc_rports. It contains the
+ * rport state machine and does all rport interaction with the transport class.
+ * There should be no other places in libfc that interact directly with the
+ * transport class in regards to adding and deleting rports.
+ *
+ * fc_rport's represent N_Port's within the fabric.
+ */
+
+/*
+ * RPORT LOCKING
+ *
+ * The rport should never hold the rport mutex and then attempt to acquire
+ * either the lport or disc mutexes. The rport's mutex is considered lesser
+ * than both the lport's mutex and the disc mutex. Refer to fc_lport.c for
+ * more comments on the heirarchy.
+ *
+ * The locking strategy is similar to the lport's strategy. The lock protects
+ * the rport's states and is held and released by the entry points to the rport
+ * block. All _enter_* functions correspond to rport states and expect the rport
+ * mutex to be locked before calling them. This means that rports only handle
+ * one request or response at a time, since they're not critical for the I/O
+ * path this potential over-use of the mutex is acceptable.

- * This routine is called by vfs_sync() to make sure that things make it

- * and when the file system is unmounted. For the vfs_sync() case, all
- * we really need to do is sync out the log to make all of our meta-data
- * updates permanent (except for timestamps). For calls from pflushd(),
- * dirty pages are kept moving by calling pdflush() on the inodes
- * containing them. We also flush the inodes that we can lock without
- * sleeping and the superblock if we can lock it without sleeping from
- * vfs_sync() so that items at the tail of the log are always moving out.
- *
- * Flags:
- * SYNC_BDFLUSH - We're being called from vfs_sync() so we don't want
- * to sleep if we can help it. All we really need
- * to do is ensure that the log is synced at least
- * periodically. We also push the inodes and
- * superblock if we can lock them without sleeping
- * and they are not pinned.
- * SYNC_ATTR - We need to flush the inodes. If SYNC_BDFLUSH is not
- * set, then we really want to lock each inode and flush
- * it.
- * SYNC_WAIT - All the flushes that take place in this call should
- * be synchronous.
- * SYNC_DELWRI - This tells us to push dirty pages associated with
- * inodes. SYNC_WAIT and SYNC_BDFLUSH are used to
- * determine if they should be flushed sync, async, or
- * delwri.
- * SYNC_CLOSE - This flag is passed when the system is being
- * unmounted. We should sync and invalidate everything.
- * SYNC_FSDATA - This indicates that the caller would like to make
- * sure the superblock is safe on disk. We can ensure
- * this by simply making sure the log gets flushed
- * if SYNC_BDFLUSH is set, and by actually writing it
- * out otherwise.
- * SYNC_IOWAIT - The caller wants us to wait for all data I/O to complete
- * before we return (including direct I/O). Forms the drain
- * side of the write barrier needed to safely quiesce the
- * filesystem.

+ it does not implement them (e.g. an audio subdev will generally not
+ implement the video category ops). The exception is the core category:
+ this must always be present.
+
+ These ops are all used internally so it is no problem to change, remove
+ or add ops or move ops from one to another category. Currently these

+ ---help---
+ This enables support for configuring Data Center Bridging (DCB)
+ features on DCB capable Ethernet adapters via rtnetlink. Say 'Y'
+ if you have a DCB capable Ethernet adapter which supports this
+ interface and you are connected to a DCB capable switch.
+
+ DCB is a collection of Ethernet enhancements which allow DCB capable
+ NICs and switches to support network traffic with differing
+ requirements (highly reliable, no drops vs. best effort vs. low
+ latency) to co-exist on Ethernet.
+
+ DCB features include:
+ Enhanced Transmission Selection (aka Priority Grouping) - provides a
+ framework for assigning bandwidth guarantees to traffic classes.
+ Priority-based Flow Control (PFC) - a MAC control pause frame which
+ works at the granularity of the 802.1p priority instead of the
+ link (802.3x).
+
+ If unsure, say N.

- ---help---
- This option will enable debug tracing output for the

-
- This will result in the kernel module being ~70k larger. You
- can control which debug output is sent to the kernel log by
- setting the value in
-
- /proc/net/ieee80211/debug_level
-
- For example:
-
- % echo 0x00000FFO > /proc/net/ieee80211/debug_level
-
- For a list of values you can assign to debug_level, you
- can look at the bit mask values in <net/ieee80211.h>
-
- If you are not trying to debug or develop the ieee80211
- subsystem, you most likely want to say N here.

- If the irq handler handles some data on the DMA buffer, it should

- That protects basically against all races among PCM callbacks, yes.
- However, there are two remaining issues:
- 1. The substream pointer you try to lock isn't protected _before_
- this lock yet.
- 2. snd_pcm_period_elapsed() itself acquires the lock.
- The requirement of another lock is because of 1. When you get
- chip->playback_substream, it's not protected.
- Keeping this lock while snd_pcm_period_elapsed() assures the substream
- is still protected (at least, not released). And the other status is
- handled properly inside snd_pcm_stream_lock() in
- snd_pcm_period_elapsed().

Normally ASoC codec drivers are only built if a machine driver which
uses them is also built since they are only usable with a machine
driver. Selecting this option will allow these drivers to be built
without an explicit machine driver for test and development purposes.
+ Support for the bus types used to access the codecs to be built must
+ be selected separately.
+
If unsure select "N".
