Subject: iwlagn: move Tx datapath to transport layer

Split the Tx datapath in two parts:
* the first deals with the Tx cmd composition
* the second attaches the skb + Tx cmd to the queues

Subject: iwlagn: move the tasklet / irq to the transport layer

PCIe doesn't provide any ISR registration API, whereas other buses do.
Hence, we need to move the tasklet and irq to the transport layer to allow this
flexibility.

Subject: iwlagn: move sync_irq to transport layer

Since all the irq / tasklet is now handled in the transport layer, it should
give an API to ensure that all the irq / tasklet have finished running. This
will allow the upper layer to release all its resources.

Subject: iwlagn: move the Rx dispatching to the upper layer

The upper layer receives a pointer to an iwl_rx_mem_buffer. I would prefer the
upper layer to receive a pointer to an iwl_rx_packet, but this is impossible
since the Rx path needs to add the address of the page to the skb.
I may find a solution later.

All the pre_rx_handler and notification code has been moved to the upper layer.

Subject: iwlagn: simplify TX flags assignments

The first assignment of TX_CMD_FLG_SEQ_CTL_MSK for
ack-expected mgmt frames is overwritten later in
the function, so it's useless. Also, probe response
frames, BACK request and others there are mutually
exclusive so can be moved into an else branch.

From ab697a9f1e73ba817955e15bd899a8a0627f9fd6 Mon Sep 17 00:00:00 2001
From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
Date: Mon, 11 Jul 2011 07:35:34 -0700
Subject: iwlagn: move rx transport functions to iwl-trans-rx-pcie.c

Also create a new file: iwl-trans-int-pcie.h which will include
the non static functions that are shared among the current pcie transport layer.

- * Rx theory of operation
- *
- * Driver allocates a circular buffer of Receive Buffer Descriptors (RBDs),
- * each of which point to Receive Buffers to be filled by the NIC.  These get
- * used not only for Rx frames, but for any command response or notification
- * from the NIC.  The driver and NIC manage the Rx buffers by means
- * of indexes into the circular buffer.
- *
- * Rx Queue Indexes
- * The host/firmware share two index registers for managing the Rx buffers.
- *
- * The READ index maps to the first position that the firmware may be writing
- * to -- the driver can read up to (but not including) this position and get
- * good data.
- * The READ index is managed by the firmware once the card is enabled.
- *
- * The WRITE index maps to the last position the driver has read from -- the
- * position preceding WRITE is the last slot the firmware can place a packet.
- *
- * The queue is empty (no good data) if WRITE = READ - 1, and is full if
- * WRITE = READ.
- *
- * During initialization, the host sets up the READ queue position to the first
- * INDEX position, and WRITE to the last (READ - 1 wrapped)
- *
- * When the firmware places a packet in a buffer, it will advance the READ index
- * and fire the RX interrupt.  The driver can then query the READ index and
- * process as many packets as possible, moving the WRITE index forward as it
- * resets the Rx queue buffers with new memory.
- *
- * The management in the driver is as follows:
- * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free.  When
- *   iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
- *   to replenish the iwl->rxq->rx_free.
- * + In iwl_rx_replenish (scheduled) if 'processed' != 'read' then the
- *   iwl->rxq is replenished and the READ INDEX is updated (updating the
- *   'processed' and 'read' driver indexes as well)
- * + A received packet is processed and handed to the kernel network stack,
- *   detached from the iwl->rxq.  The driver 'processed' index is updated.
- * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free
- *   list. If there are no allocated buffers in iwl->rxq->rx_free, the READ
- *   INDEX is not incremented and iwl->status(RX_STALLED) is set.  If there
- *   were enough free buffers and RX_STALLED is set it is cleared.
- *
- *
- * Driver sequence:
- *
- * iwl_rx_queue_alloc()   Allocates rx_free
- * iwl_rx_replenish()     Replenishes rx_free list from rx_used, and calls
- *                            iwl_rx_queue_restock
- * iwl_rx_queue_restock() Moves available buffers from rx_free into Rx
- *                            queue, updates firmware pointers, and updates
- *                            the WRITE index.  If insufficient rx_free buffers
- *                            are available, schedules iwl_rx_replenish
- *
- * -- enable interrupts --
- * ISR - iwl_rx()         Detach iwl_rx_mem_buffers from pool up to the
- *                            READ INDEX, detaching the SKB from the pool.
- *                            Moves the packet buffer from queue to rx_used.
- *                            Calls iwl_rx_queue_restock to refill any empty

Subject: iwlagn: move tx transport functions to iwl-trans-tx-pcie.c

There are still a few functions here and there that should be
put in the transport layer. Mainly the functions that are related to the reclaim flow.

+ * Theory of operation
+ *
+ * A Tx or Rx queue resides in host DRAM, and is comprised of a circular buffer
+ * of buffer descriptors, each of which points to one or more data buffers for
+ * the device to read from or fill.  Driver and device exchange status of each
+ * queue via "read" and "write" pointers.  Driver keeps minimum of 2 empty
+ * entries in each circular buffer, to protect against confusing empty and full
+ * queue states.
+ *
+ * The device reads or writes the data in the queues via the device's several
+ * DMA/FIFO channels.  Each queue is mapped to a single DMA channel.
+ *
+ * For Tx queue, there are low mark and high mark limits. If, after queuing
+ * the packet for Tx, free space become < low mark, Tx queue stopped. When
+ * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
+ * Tx queue resumed.

- * Theory of operation
- *
- * A Tx or Rx queue resides in host DRAM, and is comprised of a circular buffer
- * of buffer descriptors, each of which points to one or more data buffers for
- * the device to read from or fill.  Driver and device exchange status of each
- * queue via "read" and "write" pointers.  Driver keeps minimum of 2 empty
- * entries in each circular buffer, to protect against confusing empty and full
- * queue states.
- *
- * The device reads or writes the data in the queues via the device's several
- * DMA/FIFO channels.  Each queue is mapped to a single DMA channel.
- *
- * For Tx queue, there are low mark and high mark limits. If, after queuing
- * the packet for Tx, free space become < low mark, Tx queue stopped. When
- * reclaiming packets (on 'tx done IRQ), if free space become > high mark,
- * Tx queue resumed.

Subject: iwlagn: move iwlagn_stop_device to transport layer

Since iwlagn_stop_device was the only caller to the rx_stop / tx_stop,
these two don't need to be API any more.

Since iwlagn_rx_handler_setup is always called, fold it into
iwl_rx_handler_setup. BT related handlers are setup by the new
bt_rx_handler_setup lib_ops.

From 6bd4dba3d2b8a90d27dfd32b306fa965650599b4 Mon Sep 17 00:00:00 2001
From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
Date: Sun, 3 Jul 2011 15:45:34 +0300
Subject: iwlagn: kill iwlagn_setup_deferred_work

Since iwlagn_setup_deferred_work is always called, fold it into
iwl_setup_deferred_work. BT related works are setup by the new
bt_setup_deferred_work lib_ops.

From 392f8b789a4c96b39d527ff8ea5ceba20cd79d56 Mon Sep 17 00:00:00 2001
From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
Date: Sun, 10 Jul 2011 15:30:15 +0300
Subject: iwlagn: move more functions from the start flow to the transport
 layer

Basically all the nic_init flow should be in the transport layer.
iwl_prepare_card_hw will move to the transport too in a separate patch.

Subject: iwlagn: transport layer receives struct iwl_trans*

It still holds a pointer to iwl_priv. But hopefully this will disappear at some point.
Also add the multiple inclusion protection to iwl-trans.h that was forgotten.
Move iwl-trans structures to iwl-trans.h

From d593411084a56124aa9d80aafa15db8463b2d8f7 Mon Sep 17 00:00:00 2001
From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
Date: Mon, 11 Jul 2011 10:48:51 +0300
Subject: iwlagn: simplify the bus architecture

Call iwl_probe with a ready iwl_bus struct. This means that the bus layer
assigns the irq, dev and iwl_bus_ops pointers to iwl_bus before giving it to
iwl_probe.

The device specific struct is allocated together with the common iwl_bus struct
by the bus specific layer. The pointer to the aggregate struct is passed to the
upper layer that holds a pointer to iwl_bus instead of an embedded iw_bus.
The private data given to the PCI subsystem is now iwl_bus and not iwl_priv.

Provide bus_* inliners on the way in order  to simplify the syntax.

Rename iwl-pci.h -> iwl-bus.h since it is bus agnostic and represent the
external of the bus layer.

From c1c81401de30448baf35ec2f689ad21faffb0536 Mon Sep 17 00:00:00 2001
From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
Date: Mon, 11 Jul 2011 11:18:48 +0300
Subject: iwlagn: iwl_bus holds drv_data as void * instead of iwl_priv

The price to pay is the access to the log system. Therefore logs from bus layer
are sent by dev_printk instead of IWL_XXXX.

Rename bus->priv to bus->drv_data to make the separation even clearer.

Subject: iwlagn: add comment to warn about WoWLAN in resume / suspend flows

WoWLAN may need the NIC even after suspend. One should not do anything to the
NIC in the bus level, since one cannot check whether WoWLAN is enabled or not.
Same for resume.

Add a simple comment to the code to warn about this.

Subject: iwlagn: remove forgotten debugfs function

It seems that due to merge issues between different
trees or so this function prototype wasn't removed
when it should have been, do it now.

Subject: iwlagn: rewrite HW crypto

As I just discovered while doing WoWLAN, HW crypto
is done wrong for GTKs: they should be programmed
for the AP station ID (in the managed mode case)
and the HW can actually deal with multiple group
keys per station as well (which is useful in IBSS
RSN but that I've chosen not to use this).

To fix all this, modify the way keys are sent to
the device and key offsets are allocated. After
these changes, key offsets are stored into the
hw_key_idx which we can then track for the key
lifetime, not relying on our sta_cmd array. WEP
default keys get special treatment, of course.

Additionally, since I had the API for it, we can
now pre-fill TKIP phase 1 keys for RX now that we
can obtain the P1K from mac80211, a capability I
had added for WoWLAN initially.

Finally, some keys simply don't need to be added
into the device's key cache -- a key that won't
be used for RX is only needed in the TX header,
so "pretend" to have accepted any key without
adding it into the device -- no need to use up
key space there for it.

From c8ac61cf6e53fefb3b439fc58390fb65d2730e63 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Fri, 15 Jul 2011 13:23:45 -0700
Subject: iwlagn: implement WoWLAN

Implement WoWLAN support in iwlagn. The device
supports a number of wakeup triggers and can do
GTK rekeying when asleep (if HW crypto is used).
Unfortunately, we need to disconnect from the AP
after resume since we can't yet get all the info
out of the wowlan uCode to stay connected safely.

Subject: iwlagn: track beacon interval sent to device

Sometimes, when mac80211 changes the beacon
interval or when it isn't yet set in mac80211
before association, the uCode will sysassert
because we send it confusing RXON timing vs.
PAN parameters. To fix this, track the last
beacon interval sent to the device and use
that in PAN parameter calculations.

This fixes a bug during P2P group formation
as a client (and possibly association to a
regular AP) while connected to another AP.

Subject: iwlagn: rename iwlagn_set_dynamic_key

We now have iwlagn_set_dynamic_key() and
iwl_set_dynamic_key() which is confusing,
rename the former to iwlagn_send_sta_key()
to better reflect what it does -- it only
sends a command and doesn't change driver
state.

Subject: iwlagn: probe would crash with DEBUG_SHIRQ

This is since my patch:

    iwlagn: introduce transport layer and implement rx_init

The IRQ is requested before the locks are initialized, hence the crash.
Initialize the tasklet before we request the IRQ on the way.
