Subject: ath10k: Fix DMA burst size

A value of zero indicates that 128B is the maximum
DMA request size for read/writes. But PCI cards based
on AR9880 can support 256B, so enable this for
the 10.2 firmware.

Subject: ath10k: Enable RX batching

This feature allows the FW to batch RX indications,
reducing the rate of host interrupt generation, which
in turn reduces CPU load. Currently, this is enabled
only for the 10.2 firmware.

Subject: ath10k: Implement sta_add_debugfs

Add per station debugfs files when a station is added to mac80211's
station list. This helps to group peer specific debugfs entries
altogether. Right now this callback adds support to test aggregation
procedures (addba/addba_resp/delba) manually.

To enable automatic aggregation in target,
echo 0 >/sys/kernel/debug/ieee80211/phyX/netdev:wlanX/
	stations/XX:XX:XX:XX:XX:XX/aggr_mode

For manual mode,
echo 1 >/sys/kernel/debug/ieee80211/phyX/netdev:wlanX/
	stations/XX:XX:XX:XX:XX:XX/aggr_mode

as input.

To send addba,

Subject: ath10k: Fix potential Rx ring corruption

When replenishing Rx buffers driver updates the address of the
buffer and the index of rx buffer in rx ring to the firmware.
Change in order by CPU can cause rx ring corruption. Add memory
barrier before updating rx buffer index to guarantee the order.

This could fix some instances of rx ring corruption due to done
bit in rx attention flag not set.

Subject: ath10k: implement prb tmpl wmi command

New firmware revisions with beacon templates need
probe templates as well because they don't forward
probe requests to host at all.

This is required for new firmware to work with
direct probe requests (notably required by hidden
ssid AP).

Subject: ath10k: fix duration calculation for quiet param

The duty cycle (% of quiet duration) is used to put the device
in quiet mode for the given period. Currently the quiet duration
is wrongly calculated which results in not enabling quiet mode.
Fix the calculation as below

     duration = (period * duty cycle) / 100

Subject: ath10k: prevent fw reg dump spam

Originally the explicit fw register dump was added
to wait_for_target_init because interrupts are
masked early during power_up.

Due to some changes in power_up/reset sequences
sometimes when fw crashed ath10k would print the
dump more than once via hif_stop -> warm_reset ->
wait_for_target_init, possibly with different
values each.

Prevent this by doing the explicit fw register
dump only during power_up instead of
wait_for_target_init.

Subject: ath10k: implement diag event

Some firmware revisions may report this event as
part of their diagnostics.

This avoids `unknown event` warnings and adds
tracing for the event.

Subject: ath10k: introduce struct ath10k_skb_rxcb

It doesn't make much sense to share the
ath10k_skb_cb with Rx path. The Rx path doesn't
need to keep any mac80211's data.

Subject: ath10k: implement rx reorder support

New firmware and firmware (qca6174 hw3.0+ and fw
266+) are capable of full aggregation rx
reordering. If it's enabled then Rx is handled via
a new, separate htt event.

The rx ring behaviour is changed a little to
support the new rx scheme. These changes shouldn't
affect qca988x performance.

Subject: ath10k: reset chip before reading chip_id in probe

There are some very rare cases with some hardware
configuration that the device doesn't init quickly
enough in which case reading chip_id yielded 0.
This caused driver to subsequently fail to setup
the device.

Subject: ath10k: add support for qca6174 Rx descriptors

The QCA6174 chip has an extra 4 bytes in
rx_ppdu_end structure which is used in htt_rx_desc
and HTT Rx ring offset setup. This is necessary
for correct Rx for QCA6174 (otherwise Rx
descriptors are overwritten and corrupted).

This means QCA988X will have an extra 4 byte
padding in Rx descriptor layout which is harmless.

Subject: ath10k: add support for qca6174

The QCA6174 in combination with new wmi-tlv firmware is capable of
multi-channel, beamforming, tdls and other features.

This patch just makes it possible to boot these devices and do some basic stuff
like connect to an AP without encryption. Some things may not work or may be
unreliable. New features will be implemented later. This will be addressed
eventually with future patches.

From b91251fbe88c9db1a7af29cfe49ca50aa4da9cd2 Mon Sep 17 00:00:00 2001
From: Michal Kazior

Subject: ath10k: split fw pdev stats parsing

This will make it easier to implement fw stats
parsing for firmware 10.2.

This also renames a few structures for
consistency.

Subject: ath10k: fix 10.2 fw stats parsing

Both 10.2 firmware binaries 10.2-00082-4 and
10.2.4.20 have introduced ABI changes to fw_stats
each. This caused fw_stats to output wrong data.

Define new structures and use them to parse the
statistics correctly.

Subject: ath10k: use idr api for msdu_ids

HTT Tx protocol uses arbitrary host assigned ids
too associate with MSDUs when delivering
completions.

Instead of rolling out own id generation scheme
use the tools provided in kernel.

This should have little to no effect on
performance.

Subject: ath10k: fix dtim period with beacon templates

Firmware supporting beacon templates (i.e. wmi-tlv
for qca6174) doesn't implicitly take dtim period
from the template. Instead it requires vdev param
to be set accordingly.

This fixes dtim period being stuck at 3.

Subject: ath10k: fix nullfunc workaround

The workaround couldn't work correctly because the
802.11 header wasn't properly stripped of QoS Data
bit so it wasn't recognized in the later parts of
tx path as NullFunc frame and ended up in HTT Tx
instead of HTT Mgmt Tx.

Subject: ath10k: disable irqs after fw crash

It makes little sense to keep handling irqs if fw
is dead.

This prevents multiple fw register dumps upon
crash on some devices (seen on QCA6174).

Subject: ath10k: fix pmf for wmi-tlv on qca6174

New wmi-tlv firmware uses HTT 3.0 protocol which
uses TX_FRM command for management frames (instead
of a dedicated command). To support PMF it is
necessary to provide explicit tailroom.

Subject: ath9k and ath9k_htc: rename variable "led_blink"

ath9k and ath9k_htc use the variable name "led_blink" to indicate
whether the module parameter "blink" is on. This name is easy to
conflict with other variables, and has caused a compiler error found
by kbuild test bot. The compiler error is as following:

drivers/net/wireless/ath/ath9k/ath9k_htc.o:(.data+0x47c): multiple definition of `led_blink'
drivers/net/wireless/ath/ath9k/ath9k.o:(.bss+0x20): first defined here

Subject: wil6210: fix timing of netif_carrier_on indication

netif_carrier_on indication was too late. In case Rx packet received
before netif_carrier_on indication, upper layers could not send
Tx packet back.

The fix is to indicate netif_carrier_on earlier:
for STA, indicate netif_carrier_on when association starts.
for AP/PCP, indicate netif_carrier_on upon starting AP/PCP.

Subject: wil6210: ignore firmware failure to gracefully stop AP

upon cfg80211_stop_ap, a graceful AP shutdown is requested from firmware
followed by firmware reset.
In case graceful request failed, error was returned to cfg80211.

The change is to return success in this scenario, because firmware
reset will anyhow shutdown the AP.

Subject: wil6210: tuning rings size

Tuning rings size for performance optimization.
Increasing Tx ring size, allows buffering more packets for HW, thus
eliminating idle periods which were observed with smaller ring at
high throughput, because HW was fetching packets faster than driver was
filling them into the TX ring. Rx ring was similarly increased to
avoid same problems in Rx.

Subject: wil6210: remove unnecessary interrupt moderation module parameters

Interrupt moderation parameters will never be passed as module
parameters. For product, they will be hard-coded after lab testing,
and for debugging, they can be altered via debugfs.

Subject: ath9k: Update QCA953x initvals

This patch disables HW peak detect calibration for
QCA953x, since it is problematic on a few boards.
Instead, manual calibration will be done in the
driver.

Subject: ath9k: Enable manual peak detect calibration

On some AR955x/QCA953x boards, noise floor calibration
gets stuck and the cause is a hardware/BB issue. To fix
this, peak detect calibration in the HW is disabled
and is done in the driver instead. There a few differences
with the calibration routine for older chips like
AR9331.

mac80211 already requests WMM per vif but firmware
wasn't able to handle this until now. However new
wmi-tlv firmware for qca6174 is capable of this.

This prepares per-vif WMM param setup.

Subject: ath10k: implement sta keepalive command

New wmi-tlv firmware for qca6174 has STA keepalive
service available. The service can provide
automatic idle connection polling via NullFunc
frames to AP when acting as a client.

Subject: ath10k: disable sta keepalive

Firmware revisions providing sta keepalive service
have it enabled by default.

mac80211 already does idle connection polling so
it makes no sense to duplicate this in ath10k.
mac80211 wouldn't even know of the offloaded
keepalive NullFunc frames.

This prevents sending out some extraneous frames
on the air.

Subject: ath10k: fix target wakeup timeout

During drv_start/drv_stop stress testing in ARM platform,
sometimes target is taking more that 5ms to wake up. Similar
behaviour also noted during driver load and unload iterations.
On such cases, the wakup duration lies between 5-6ms. Hence
increasing pci wakup timeout 10ms to be more safer. With this
changes, able to complete power down/up >100 iterations without
any issues.

Subject: ath9k: Remove redundant device_can_wakeup() check

WOW capability is registered with mac80211 only when
the device has the ability to wakeup, so there is no
need to check in the suspend() routine.

Subject: ath9k: Fix wow init/deinit

Registering the card as a wakeup source needs to
be done once, during initialization. When the WOW
configuration changes, the card's status as wakeup
source needs to be changed too and this is done
via the set_wakeup() callback. Also, make sure
the device is removed properly using ath9k_deinit_wow().

Subject: ath9k: Check WOW triggers properly

This patch makes sure that valid WOW triggers
are present before trying to suspend the device.
Also, introduce and use ATH_OP_WOW_ENABLED to
bypass PCI suspend and clear it in resume().

From c65fb2637a5c772faaea50e19813bb52e66b0006 Mon Sep 17 00:00:00 2001
From: Sujith Manoharan
Date: Fri, 30 Jan 2015 19:05:35 +0530
Subject: ath9k: Remove incorrect register macros

These macros are applicable to pre-AR9003 chips
and the addresses are different for the AR9003
family. Since they are unused anyway, remove them.

Subject: ath9k: Fix max pattern check

Since the maximum number of configurable patterns
is chip-specific, use the HW capability instead
of a fixed value for checking if a free pattern
slot is available.

Subject: ath10k: prevent setting wrong key idx for station

Ath10k driver sets wrong default key idx that results in
sending unicast frames with multicast key.

The reason for this behavior is that cached broadcast key
is installed for station MAC address on association. After
dot1x completes, unicast key is installed for station
MAC address. Default key idx is set to broadcast key id when
driver tries to send broadcast frame. This causes firmware
to use broadcast key id to transmit unicast frames to stations.

Used TX_USAGE flag to set default key for stations.

Added callback for setting unicast default idx which will be
invoked on every default key idx configuration.

To prevent this make sure to release ar->data_lock
while calling to ath10k_wmi_beacon_send_ref_nowait().

Subject: ath10k: Use TX cksum offload only for CHECKSUM_PARTIAL

Otherwise ath10k will just checksum everything even if it did not
go through the TCP/IP stack (for example bridged frames). In the worst
case this could mean recreating the checksum for incorrect data.

Subject: ath10k: add log level configuration for fw_dbglog

Introduce an optional log level configuration for the existing debugfs fw_dbglog file. It
allows users to configure the desired log level for firmware dbglog messages.

To configure log level as WARN:

echo 0xffffffff  2 > /sys/kernel/debug/ieee80211/phy0/ath10k/fw_dbglog

The values are:

VERBOSE		0
INFO		1
WARN		2
ERR		3

Subject: ath10k: enable qca6174 hw3.2

The 3.2 revision has a different target BMI
version so it wasn't recognized by ath10k (despite
the chip_id rev being on the supported list
already).

Subject: ath9k: Add support for more WOW patterns

Newer chips like WB222, WB335 support more than
8 user-configurable patterns. This patch adds
support for it by setting up the correct HW
registers.

Subject: ath9k: Fix issues with WoW enable

This patch addresses several issues with the
ath9k_hw_wow_enable() routine:

* The usage of set/clr variables is removed. Writing
  the required values to registers is cleaner.

* The shift value of 28 for the contention window field
  in AR_WOW_PATTERN is incorrect, change it to 27.

* Disabling Keep Alive needs to be done based on the
  LINK_CHANGE option. This is done unconditionally now,
  fix this.

* The workaround for the D1/D3 issue is required only
  for AR9462.

* The bitfield for enabling pattern matching for packets
  less than 256 bytes has expanded for new chips, handle
  this accordingly.

* General cleanup.

Subject: ath5k: fix spontaneus AR5312 freezes

Sometimes while CPU have some load and ath5k doing the wireless
interface reset the whole WiSoC completely freezes. Set of tests shows
that using atomic delay function while we wait interface reset helps to
avoid such freezes.

The easiest way to reproduce this issue: create a station interface,
start continous scan with wpa_supplicant and load CPU by something. Or
just create multiple station interfaces and put them all in continous
scan.

This patch partially reverts the commit 1846ac3dbec0 ("ath5k: Use
usleep_range where possible"), which replaces initial udelay()
by usleep_range().

I do not know actual source of this issue, but all looks like that HW
freeze is caused by transaction on internal SoC bus, while wireless
block is in reset state.

Also I should note that I do not know how many chips are affected, but I
did not see this issue with chips, other than AR5312.

The relay_close() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
