Subject: ath6kl: store firmware logs in skbuffs

Currently firmware logs are stored in a circular buffer, but this was
not very flexible and fragile. It's a lot easier to store logs to struct
skbuffs and store them in a skb queue. Also this makes it possible
to easily increase the buffer size, even dynamically if we so want (but
that's not yet supported).

From user space point of view nothing should change.

Subject: ath6kl: add blocking debugfs file for retrieving firmware logs

When debugging firmware issues it's not always enough to get
the latest firmware logs, sometimes we need to get logs from a longer
period. To make this possible, add a debugfs file named fwlog_block. When
reading from this file ath6kl will send firmware logs whenever available
and otherwise it will block and wait for new logs.

From b29072cc7b0e08ace48ab709c40cf6246fb2e8b0 Mon Sep 17 00:00:00 2001
From: Chilam Ng <chilamng@qca.qualcomm.com>

Subject: ath6kl: prioritize Tx bundling based on AC priorities

Tx bundling is the more efficient use of SDIO bus and allows more packet
transfers with fewer bus transactions, and is a way to improve overall
throughput. However, Tx bundling has only 4 scatter request resources available.
When there are multiple traffic streams of different priorities, it's possible
that lower priority traffic may hog all the scatter requests and lock out the
higher prioirty traffic from bundling.
Tx bundling is now enabled per AC. When an AC do a scatter request and
the remaining scatter request resources is lower than a configurable
threshold, it will disable Tx bundling for all AC's of lower priorities.
When an AC has Tx bundling disabled and has no Tx bundles sent in a
consecutive and configurable number of packets, Tx bundling will be re-enabled
for that AC.

Subject: ath6kl: Fix firmware crash dump

The firmware crash dump printout was wrong as it was using incorrect
offsets.

kvalo: improve commit log, change the "%d:" to print word indexes, not bytes

Subject: ath6kl: Add unicast mgmt frame buffering

PS buffering of unicast Action frames that are sent in a context
of a BSS. In AP mode when the recepient station goes to powersave
and PS_POLL flag is not set, we would buffer the frames. Send out
unicast mgmt bufferred frame when PS_POLL is received.

This fixes a bug in P2P GO behavior when sending a GO Discoverability
Request to a client that is in sleep mode.

Subject: ath6kl: assign Tx packet drop threshold per endpoint based on AC
 priority

Tx packets will begin to drop when there are multiple traffic priorities
and the current traffic is not the highest priority and the remaining
cookies drop below a certain number, which is fixed for all AC. It is
possilbe that lower priority AC have more traffic which will consume
more cookies and lock out higher priority AC from having any. Assign
each endpoint (AC) with a different Tx-packet-drop threshold so lower
priority AC is more likely to drop packets and the cookies become more
available to higher priority AC.

In ath6kl_cfg80211_add_key(), params is checked for non-NULL
but this pointer has been deferenced many times before this check. This
gives the following smatch warning. add_key() can never carry NULL as
params, remove this bogus check.

Subject: ath6kl: Make sure to allocate rx buffers after the endpoint
 connection

Rx buffers should be allocated for control and best effort endpoints only
after the enpoints connection is esablished. But this is done before the
endpoint connection is complete, we don't even the control and BE endpoints
that time. Move the buffer allocation after endpoint connection is over,
after ath6kl_init_hw_start(). Found in review, never seen any real issue
with this.

Subject: ath6kl: Make foreground scan a deterministic one

This makes the device get into scan state as soon as a
scan request is received, instead of blocking the scan
request till the traffic comes down. It is  necessary
for the deterministic foreground scan particularly when
having multiple vif operating where, if the scan is non-
deterministic, scan on one interface will not start
as long as there are traffic on the other interface. This
change passes 50 msec as foreground scan interval to fix this.

Subject: ath6kl: Lower SDIO pad drive strength for hw2.1.1 board

Without this change, SDIO shuts down due to CRC error during
data communication to the firmware in some of the platform.
for example, scan request issued to the firmware doesn't
return scan completed events and cause the socket interface
to always return -16 (device busy).

SDIO pad drive strength should be reduced for hw2.1.1 board
to avoid such errors.

Subject: ath6kl: Skip vif index validation in ath6kl_rx() for wmi events

When the wmi event is vif specific, the validation of vif index
is taken care in ath6kl_wmi_proc_events_iface(). This also avoids
the need for a netdev to be registered while receiving initial events
like "target_ready" and "regulatory domain".

Subject: ath6kl: Defer wiphy and netdev registration till the end of
 ath6kl_core_init()

This makes the wiphy and initial netdev registration the last step
in dev initialization. Apart from the fact that this looks right,
it can also be used to setup wiphy with the regulatory information
received from firmware after uploading the firmware. Also it fixes
a FIXME in ath6kl_core_init() where mac address is copied into
netdev->dev_addr, ath6kl_interface_add() takes care of this as well.

Subject: ath6kl: Make sure wiphy is registered before calling
 regulatory_hint()

As regulatory events are processed even before the wiphy is registered,
calling regulatory_hint() at early stage should be fixed.

Subject: ath6kl: Clear the IE in firmware if not set

Remove check so that IE in firmware is cleared if not set. Without this fix, any
previously set IE will be used incorrectly in the next frame. For example,
consider the scenario where a P2P device scan is followed by a regular station
scan. The P2P IE set by the P2P scan needs to be cleared, otherwise the station
scan will contain the P2P IE.

Firmware sends logs to host once the 1500 byte log buffer
has been filled. At time of assert, there could be residue
logs lying in the firmware. This patch pulls those residue
logs. This would give the full picture of the firmware.

Subject: ath6kl: Fix random system lockup

The commit "ath6kl: Use a mutex_lock to avoid
race in diabling and handling irq" introduces a
state where ath6kl_sdio_irq_handler() would be waiting
to claim the sdio function for receive indefinitely
when things happen in the following order.

ath6kl_sdio_irq_handler()
	- aquires mtx_irq
	- sdio_release_host()
					ath6kl_sdio_irq_disable()
						- sdio_claim_host()
						- sleep on mtx_irq
	ath6kl_hif_intr_bh_handler()
		- (indefinitely) wait for the sdio
		  function to be released to exclusively claim
		  it again for receive operation.

Fix this by replacing the mtx_irq with an atomic
variable and a wait_queue.

kvalo: add ath6kl_sdio_is_on_irq() due to open parenthesis alignment

Subject: ath6kl: Fix kernel panic while receiving fwlog during boot

"ath6kl: Defer wiphy and netdev registration till the end of ath6kl_core_init()"
causes kernel panic by accessing the unallocated debug resources during
boot time. To fix this, split the debug initialization funtion into two,
one initializes the debug resource and the other takes care of debugfs
initialization. When this issue shows up the kernel crash dump would
look like

Subject: ath6kl: Add provision to define suspend policy in disconnected state.

It gives flexibility to the user to define suspend policy
when the suspend mode is set to WOW and the device is in
disconnected state at the time of suspend.

New module parameter wow_mode is added to get the choice
from the user. This parameter is valid only if the module
parameter suspend_mode is set to WOW.

To force WOW in connected state and cut power
in disconnected state:
  suspend_mode=0x3 wow_mode=0x1

To force WOW in connected state and deep sleep
in disconnected state (this is also the default wow_mode):
   suspend_mode=0x3 wow_mode=0x2

If there is no value specified to wow_mode during insmod,
deep sleep mode will be tried in the disconnected state.

Subject: ath6kl: Check wow state before sending control and data pkt

Below two scenarios are taken care in this patch which helped
to fix the firmware crash during wow suspend/resume.

* TX operation (ctrl tx and data tx) has to be controlled based
  on suspend state. i.e, with respect to WOW mode, control packets
  are allowed to send from the host until the suspend state goes
  ATH6KL_STATE_WOW and the data packets are allowed until WOW
  suspend operation starts.

* Similarly, wow resume is NOT allowed if WOW suspend is in progress.

Subject: ath6kl: Maintain the listen interval per VIF specific

Firmware has the option to support the listen interval
per vif specific. Fix this.

Listen interval can be set by the TUs or by the number
of beacons. Current code enables the user to configure
the listen interval in the unit of 'number of beacons'
using debugfs entry "listen_interval". Going forward,
we need to alter the listen interval in the unit of TUs
to get good power numbers while going to WOW suspend/resume.

Allowing the user to change the listen interval in
the unit of "number of beacons"  in debugfs and changing
listen interval in wow suspend/resume in the unit of
time (TUs) would lead us to confuse.

This patch make sures the listen interval is changed only
in the unit of time (TUs).

Subject: ath6kl: Set optimal listen intvl,bmiss,scan params while going to wow
 suspend

* In order to save the target power in WOW suspend state,
  configure the best optimal values for the below parameters,
     - listen interval.
     - beacon miss interval.
     - scan parameters.

  Default values for above attributes are reverted in
  wow resume operation.

* The default listen interval is set before the host issue
  connect request.

* New function is added to configure beacon miss count.

kvalo: minor changes to fix open parenthesis alignment

Fix the issues which checkpatch found and were easy to fix. Especially
callers of ath6kl_bmi_write() are tricky and that needs to be fixed
separately.

Subject: ath6kl: add ath6kl_bmi_write_hi32()

We have a lot of 32 bit writes to the host interest area and the code
doing that is ugly. Clean that up by adding ath6kl_bmi_write_hi32().

This also fixes few checkpatch warnings.

ipw2200 driver does not use these defines, it uses geo struct instead.
Therefore remove them from its header.

Note: we keep them in the ipw2100 driver's header, because the driver
still uses them.

Subject: rt2x00: Fix beacon skew in rt2800pci

rt2800pci is suffering from beacon skew in AP mode. Some powersaving
clients (like VOIP phones) are getting into trouble after some time
when the beacon skew is getting too big.

The ralink legacy drivers contain a function that indicates that the
beacon timer is off by 1us per tbtt. And this function works around
that by reducing the beacon interval for every 64th beacon transmission
by 64us (the smallest possible value). Do the same in rt2800pci.

This allows proper powersaving when rt2800pci is used in AP mode.

The check for PS_WAIT_FOR_TX_ACK was inverted, the hardware should only go
to full sleep if no tx is pending.

Subject: iwlwifi: abstract out missing SEQ_RX_FRAME workaround

Mohammed Shafi ran into [1] the SEQ_RX_FRAME workaround
warning with a statistics notification, this means we
can't just remove it as we'd hoped.

Abstract it out so that the higher layer can configure
this as a kind of "filter" in the transport.

Subject: iwlwifi: convert bad state message into warning

Looking at logs, I see that we did get the bad
state message a few times for some reason, but
it doesn't indicate why or where it came from,
so make it a warning in order to identify it.

Subject: iwlwifi: move wait_command_queue from shared to trans

This wait queue really belongs to the transport
layer, as it is used for sending synchronous
commands to the HW.

However, only op_mode knows about errors and
exceptional conditions, so make this queue
accessible by the op_mode.

Subject: iwlwifi: avoid some operations if no uCode loaded

Printing the SRAM and similar testmode operations could
be triggered when no uCode is loaded; prevent those
invalid operations by tracking whether uCode is loaded.

Subject: iwlwifi: explicitly track whether INIT uCode was run

Remove IWL_UCODE_NONE from enum iwl_ucode_type which,
by being the default value in 0-initialized memory,
implicitly allowed us to track whether any uCode had
ever been loaded successfully (which would have been
the INIT uCode) and instead explicitly track whether
or not INIT uCode has been run.

Subject: iwlwifi: more modularity in fw images and sections

Changed iwl_firmware_pieces structure to support an array of
separate images, and an array of sections for each image.

In fw_sec and fw_desc structures, added a field for
offset from the HW address, to support 16.0 uCode that
provides an offset instead of any other data about the section.
This field is filled with default values when parsing instruction
or data section.

From 6dfa8d019cd21d08634ceb65a3fb90d0648bd93b Mon Sep 17 00:00:00 2001
From: David Spinadel <david.spinadel@intel.com>
Date: Sat, 10 Mar 2012 13:00:14 -0800
Subject: iwlwifi: change struct iwl_fw

Change iwl_fw struct to hold an array of fw_img instead of
three separated instances.

Change fw_img to hold an array of fw_desc instead of two
separate descriptors for instructions and data.

Change load_given_ucode, load_section, verification functions
etc. to support this structure.

Subject: ath6kl: fix regression in ath6kl_upload_board_file()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

My patch 24fc32b3 ("ath6kl: add ath6kl_bmi_write_hi32()") caused a regression
in ath6kl_upload_board_file() and the board_address variable was not
properly initialised in some cases:

ath6kl/init.c:1068:6: warning: ‘board_address’ may be used uninitialized
in this function

Most likely this broke ar6004 support but I can't test that right now.

Subject: b43legacy: Load firmware from work queue instead of from probe
 routine

Recent changes in udev are causing problems for drivers that load firmware
from the probe routine. As b43legacy has such a structure, it must be changed.
As this driver loads 3 or 4 firmware files, changing to the asynchronous routine
request_firmware_nowait() would be complicated. In this implementation, the probe
routine starts a work queue that calls the firmware loading routines.

Subject: b43: Load firmware from a work queue and not from the probe routine

Recent changes in udev are causing problems for drivers that load firmware
from the probe routine. As b43 has such a structure, it must be changed.
As this driver loads more than 1 firmware file, changing to the asynchronous routine
request_firmware_nowait() would be complicated. In this implementation, the probe
routine starts a queue that calls the firmware loading routines.

Subject: mwifiex: use usleep_range instead of udelay

For the delay of 10 uSec or more usleep_range is prefered.
Unlike udelay, sleep_range avoids large number of undesired
interrupts.

Subject: mac80211: rename bss_conf timestamp to last_tsf

This value is not really very useful by itself,
yet some drivers (including iwlwifi until I can
figure out what it should do) use it. At least
rename it to "last_tsf" to indicate the meaning
and add a note that it may be really old.

I suspect the value may become useful combined
with the rx_status->mactime, but we don't (yet)
store that value and pass it to the driver.

Subject: rt2x00: Set IEEE80211_HW_REPORTS_TX_ACK_STATUS in rt2800

rt2800 already reports the tx ack status of each frame back to mac80211.
Advertise this by setting IEEE80211_HW_REPORTS_TX_ACK_STATUS for rt2800.
This allows some mac80211 features like frame loss notifications to work
with rt2800.

Subject: ath9k: Fix multi-VIF BSS handling

mac80211 provides short preamble information and ERP protection
information on a per-BSS basis, which can be used. Remove flags
stored in the driver, which was incorrect since they were being used
in a global manner.

Patch change txdone code to make it similar like txdone in rt2800pci,
process only one entry from queue matching tx status.

Before we processed all pending entries from queue until PACKEDID match,
that caused that we do not report tx statuses correctly.

Subject: rt2x00: rt2800usb: rework txstatus code

Currently we read tx status register after each urb data transfer. As
callback procedure also trigger reading, that causing we have many
"threads" of reading status. To prevent that introduce TX_STATUS_READING
flags, and check if we are already in process of sequential reading
TX_STA_FIFO, before requesting new reads.

Change timer to hrtimer, that make TX_STA_FIFO overruns less possible.
Use 200 us for initial timeout, and then reschedule in 100 us period,
this values probably have to be tuned.

Make changes on txdone work. Schedule it from
rt2800usb_tx_sta_fifo_read_completed() callback when first valid status
show up. Check in callback if tx status timeout happens, and schedule
work on that condition too. That make possible to remove tx status
timeout from generic watchdog. I moved that to rt2800usb.

Loop in txdone work, that should prevent situation when we queue work,
which is already processed, and after finish work is not rescheduled
again.

Subject: rt2x00: rt2800usb: do not check packedid for aggregated frames

Tx statuses of aggregated subframes contain packetid of first subframe
in the AMPDU. We can not identify AMPDU subframes based on packedid, so
simply assume that status match first pending frame in the queue. Thats
mostly the same what 2800pci do.

Subject: rt2x00: rt2800usb: limit tx queues length

TX status fifo is limited to 16 elements. When we send more frames than
that, we can easily loose status, what is not good for rate scaling
algorithm.

On my testing the change does not degrade performance, actually make
is slightly better. Additionally with the patch I can see much less
various rt2x00 warnings in dmesg.

TXQ_FLAG_TXOKINT_ENABLE and TXQ_FLAG_TXERRINT_ENABLE are always set and
used together, and they share the same bitmask in enum ath9k_tx_queue_flags.
Simplify the code that tests for these flags.

Limit the memset to the rx status area to improve performance.

From 377526578f2c343ea281a918b18ece1fca65005c Mon Sep 17 00:00:00 2001
From: Daniel Drake <dsd@laptop.org>

Subject: libertas: remove dump_survey implementation

libertas provides a dump_survey implementation based on reading of
a RSSI value. However, this RSSI value is calculated based on the
last received beacon from the associated AP - it is not a good
way of surveying a channel in general, and even causes an error
if the card is not associated to a network.

As this is not appropriate as a survey, remove it. This fixes an
issue where something in userspace is repeatedly calling site-survey
during boot, resulting in many repeated errors as the RSSI value cannot
be read before associating.
