Subject: ath10k: improve 'hard' simulate fw crash

Different firmware may support different numbers of
vdevs.  Use value that is always out of range for all
firmware.

Subject: ath10k: add support for 10.2 firmware

The 10.2 firmware is a successor of 10.1 firmware
(formerly identified as 10.x). Both share a lot
but have some slight ABI differences that need to
be taken care of.

The 10.2 firmware introduces some new features but
those can be added in subsequent patches. This
patch makes ath10k boot and work with 10.2 with
comparable functionality to 10.1.

Subject: ath10k: fix aggregated 4addr Rx

A-MSDU 4addr frames weren't reconstructed properly
and in some cases this resulted in a warning:

 br0: received packet on wlan0.sta1 with own address as source address

Since this was only related to A-MSDU it would
trigger when more intense traffic was generated.

Subject: ath10k: improve channel switching

In some cases during heavy tx vdev stop-start
would timeout on vdev synchronization causing
traffic to stall for a few seconds.

Instead of stop-starting use a dedicated vdev
restart command and down vdevs explicitly before
doing so.

This gets rid of the synchronization
warnings/timeouts and makes channel switching
smoother during traffic.

From 855aed1220d2c94425ab01a85fe7a6f5c436940f Mon Sep 17 00:00:00 2001
From: Simon Wunderlich <sw@simonwunderlich.de>
Date: Sat, 2 Aug 2014 09:12:54 +0300
Subject: ath10k: add spectral scan feature

Adds the spectral scan feature for ath10k. The spectral scan is triggered by
configuring a mode through a debugfs control file. Samples can be gathered via
another relay debugfs file.

Essentially, to try it out:

ip link set dev wlan0 up
echo background > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl
echo trigger > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl
iw dev wlan0 scan
echo disable > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl
cat /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan0 > samples

This feature is still experimental. Based on the original RFC patch of
Sven Eckelmann.

Subject: ath6kl: convert a driver to use module_usb_driver()

This converts a driver in drivers/net/* to use the
module_usb_driver() macro which makes the code smaller and a
bit simpler.

Subject: ath10k: fix wmi service bitmap debug

The 10.x and main firmware branches have
conflicting WMI service bitmap definitions.

This also fixes WMI services parsing on big-endian
hosts and changes debugfs output to be more human
friendly.

kvalo: remove braces and the last semicolon from SVCSTR()

From 5c81c7fd62004be13a3c9345ca25607d14862cc4 Mon Sep 17 00:00:00 2001
From: Michal Kazior <michal.kazior@tieto.com>

Subject: ath10k: introduce a stricter scan state machine

This aims at fixing some rare scan bugs related to
firmware reporting unexpected scan event
sequences.

One such bug was if spectral scan phyerr reporting
prevented firmware from properly propagating scan
events to host. This led to scan timeout. After
that next scan would trigger scan completed event
first (before scan started event) leading to
ar->scan.in_progress and timeout timer states to
be overwritten incorrectly and making the very
next scan to hang forever.

structures inside parent structures. This
reduces allocations and simplifies pci probing
code.

Subject: ath10k: remove target soc ps code

The soc powersave was disabled by default. It
never was fully tested. Some hw apparently had
problems with it and the implementation itself had
a possible race.

Just remove the refcounting and simply wake up the
device when probing and put to sleep when
removing.

kvalo: make ath10k_pci_wake() and _sleep() static

- *
- * Yet there is some complexity with direct accesses because the

- * and to verify that it is awake and will remain awake.

+ * to sleep unless host tells it to (ath10k_pci_sleep).
  *
- * Usage:
+ * If host tries to access target registers without waking it up it can
+ * scribble over host memory.
  *

- *
- *   Use ath10k_pci_sleep to tell the Target that as far as
- *   this code path is concerned, it no longer needs to remain
- *   directly accessible.  BEGIN/END is under a reference counter;

Subject: ath10k: remove pci features var

The ATH10K_PCI_FEATURE_MSI_X was originally
introduced to support both chips QCA988Xv1 and
QCA988Xv2. Since v1 isn't supported anymore it
doesn't make sense to keep the feature flag
around. Since this is the last one remove the
whole thing.

Subject: ath10k: improve vdev map handling

Check vdev map has space before calling ffs,
fix invalid cleanup in failure to create vdev
case.

Open-code the BIT() logic since BIT does not properly
handle 64-bit bitfields and future patches will make
use of larger bitfields.

Subject: ath10k: unregister spectral before mac

If spectral is unregistered after mac80211, the relayfs file has already
been removed recursively by mac/cfg80211, and spectral tries to remove
the file once more, thus leading to double free problems. Better clean
up spectral before to avoid that problem.

Subject: ath10k: fix a conflict bug in wmi service bitmap

Service mapping for main firmware branch was incorrectly used for 10.x firmware
and vice-versa.  This caused wmi_services in debugfs to print wrong values.

This fixes commit cff990ce7ddd6 ("ath10k: fix wmi service bitmap debug") where
for some reason there was either a conflict that wasn't resolved properly or
git had a bad day.

ath10k_pci_diag_read32() is for reading u32 from a device and ath10k_pci_diag_read_hi()
is a helper for reading data using "host interest" table.

Subject: ath10k: provide firmware crash info via debugfs

Store the firmware registers and other relevant data to a firmware crash dump
file and provide it to user-space via debugfs. Should help with figuring out
why the firmware crashed.

kvalo: remove dbglog support, rework and refactor the code to avoid ifdefs and
otherwise simplify it as well

Subject: ath10k: rename ath10k_pci_hif_dump_area() to
 ath10k_pci_fw_crashed_dump()

Better to have a clear name for the function. While at it, clear up the title
for the register dump.

It doesn't make much sense to overwrite send_cb
and recv_cb callbacks over and over again whenever
transport starts. Just make sure to unmask copy
engine interrupts when starting.

Subject: ath10k: make sure to really disable irqs

This fixes two corner cases.

One is a race between disabling copy engine
interrupts and unhandled pending interrupts on the
host. This could end up with a runaway tasklet and
consequently memory leak of a few copy engine
rx buffers.

The other one is an unexpected (and non-maskable
via device CSR) MSI fw indication interrupt during
teardown. This could trigger the same problem as
the first corner case.

Subject: ath10k: remove early irq handling

It's not really necessary to have a dedicated irq
handler just for the sake of catching early fw
crashes anymore. It is now safe to use one handler
even during early stages of device boot up.

Subject: ath10k: rework posting pci rx buffers

It was possible on a host system running low on
memory to end up with no rx buffers on pci pipes.

This makes the driver more robust as it won't fail
to start if it can't allocate all rx buffers right
away. If it is fatal then upper layers will notice
trouble anyway.

Subject: ath10k: update comment regarding warm reset

The old comment was a little out of date. HTT Rx
ring is a more relevant problem when stopping
transport layer.

There are basically no more uses for
ar_pci->started. It is also perfectly safe to call
hif_stop without hif_start now.

Subject: ath10k: flush hif buffers before recovery

Transport buffers weren't flushed and processed
before queueing hw recovery request to mac80211.

This could in theory result in an unwanted htt/wmi
rx events being processed while mac80211 recovers
the device and possibly interfere or even crash
the system.

Subject: ath10k: fix fw crash dumping

Recent crash dump patches introduced a regression.
If debugfs was disabled upon crash user could only
see the following:

 [  793.880000] ath10k: firmware crashed! (uuid n/a)
 [  793.890000] ath10k: qca988x hw2.0 (0x4100016c, 0x043202ff) fw 10.1.467.2-1 api 2 htt 2.1
 [  793.890000] ath10k: debug 0 debugfs 0 tracing 0 dfs 1

The report was missing register dump. Fix it by
printing registers regardless if crash_data is
present or not.

It doesn't make much sense to have copy engine
configuration structures spread across the whole

Subject: ath10k: dont duplicate service-pipe mapping

The mapping is already defined in a structure. It
makes little sense to duplicate information stored
in it within a function.

Subject: ath10k: make target endianess more explicit

Some copy engine structures are target specific
and are uploaded to the device during
init/configuration.

This also cleans up a bit diag_mem_read/write
implicit byteswap mess leaving only
diag_access_read/write with an implicit endianess
byteswap.
