Peter Oh fbc03a466f ath10k: update tx path to support QCA99X0
Since QCA99X0 uses fragmentation descriptor differently from
other ones on tx path, we need to handle it separately.

QCA99X0 is using 48 bits for address and 16 bits for length
out of 2 dword and each values have to be programmed by frag
desc base addr + msdu id, so that hardware can retrieve
corresponding frag data.

Vasanthakumar Thiagarajan acd195800f ath10k: delay device access after cold reset
It is observed that during cold reset pcie access right
after a write operation to SOC_GLOBAL_RESET_ADDRESS causes
Data Bus Error and system hard lockup. The reason
for bus error is that pcie needs some time to get
back to stable state for any transaction during cold reset. Add
delay of 20 msecs after write of SOC_GLOBAL_RESET_ADDRESS
to fix this issue. This patch is tested on QCA988X. This is
also tested on QCA99X0 which is WIP.

Miaoqing Pan 6301566e0b ath9k: export HW random number generator
We measured the FFT-based entropy in 3 ways, Shannon entropy,
collision entropy, and directly measured min-entropy. Just to
be conservative, we recommend the estimated min-Entropy to be
10 bits per 16-bit value.

Analysis was done by Jacobson,David(djacobso@qti.qualcomm.com).

Michal Kazior 92cd403228 ath9k: fix moredata flag endianness in cabq tx
While compiling ath9k with some extra flags I've
found that:

 ath9k/xmit.c +2473 ## 16: warning: restricted __le16 degrades to integer
 ath9k/xmit.c +2474 ## 36: warning: invalid assignment: &=
 ath9k/xmit.c +2474 ## 36:    left side has type restricted __le16
 ath9k/xmit.c +2474 ## 36:    right side has type int

There's no way for frame ftype/stype to be
mistreated as the offending 'moredata' flag when
considering cab queue.

This could've however theoretically led sometimes
to increased power consumption on connected
stations as they would keep their Rx active
waiting for frames that would never come.

Felix Fietkau e60ac9c7a4 ath9k: make DMA stop related messages debug-only
A long time ago, ath9k had issues during reset where the DMA engine
would stay active and could potentially corrupt memory.
To debug those issues, the driver would print warnings whenever they
occur.

Nowadays, these issues are gone and the primary cause of these messages
is if the MAC is stuck during reset or busy processing a long
transmission. This is fairly harmless, yet these messages continue to
worry users.

To reduce the number of bogus bug reports, turn these messages into
debug messages and count their occurence in the "reset" debugfs file.

Zefir Kurtisi 8fc2b61a36 ath9k: DFS - add pulse chirp detection for FCC
FCC long pulse radar (type 5) requires pulses to be
checked for chirping. This patch implements chirp
detection based on the FFT data provided for long
pulses.

A chirp is detected when a set of criteria defined
by FCC pulse characteristics is met, including
* have at least 4 FFT samples
* max_bin index moves equidistantly between samples
* the gradient is within defined range

The chirp detection has been tested with reference
radar generating devices and proved to work reliably.

Raja Mani d9156b5f68 ath10k: configure frag desc memory to target for qca99X0
Pre qca99X0 chipsets follows the model where dynamically allocate
memory for frag desc on getting new skb for TX. But, this is not
going to be the case in qca99X0. It expects frag desc memory to be
allocated at boot time and let the driver to reuse allocated memory
after every TX completion. So there won't be any dynamic frag memory
memory allocation in qca99X0 during data transmission.

qca99X0 hardware doesn't need fragment desc address to be programmed
in msdu descriptor for every data transaction. It needs to know only
starting address of fragment descriptor at the time of the boot.
During data transmission, qca99X0 hardware can retrieve corresponding
frag addr by adding programmed frag desc base addr + msdu id.

Allocate continuous fragment descriptor memory (same size as number of
descriptor) at the time of target initialization and configure allocated
dma address to the target via HTT_H2T_MSG_TYPE_FRAG_DESC_BANK_CFG.

How this is allocated continuous memory is going to be used is not
covered in this patch. It just allocates memory and hand over to firmware.
If we don't do it at init time, qca99X0 will stall when firmware tries
to do TX.

Due to 512 client support in 10.4 firmware, size of tim ie is going
to be slightly higher than non 10.4 firmware. So, size of tim_bitmap
what is carried in swba event from 10.4 firmware is bit higher.

The only bottle neck to reuse existing swba handler
ath10k_wmi_event_host_swba() for 10.4 is that code designed to deal
with fixed size tim bitmap(ie, tim_info[].tim_bitmap in wmi_swba_ev_arg).
This patch removes such size limitation and makes it more suitable
to handle swba event which has different size tim bitmap.

All existing swba event parsing functions are changed to adapt this
change. Actual support to handle 10.4 swba event is added in next patch.

Zefir Kurtisi b24fc6fc7c ath: DFS - limit number of potential PRI sequences
In the PRI detector, after the current radar pulse
has been checked agains existing PRI sequences, it
is considered as part of a new potential sequence.

Previously, the condition to accept a new sequence
was to have at least the same number of pulses as
the longest matching sequence. This was wrong,
since it led to duplicates of PRI sequences.

This patch changes the acceptance criteria for new
potential sequences from 'at least' to 'more than'
the longest existing.

Detection performance remains unaffected, while
the number of PRI sequences accounted at runtime
(and with it CPU load) is reduced by up to 50%.

As we're running out of hardware capability flags pretty quickly,
convert them to use the regular test_bit() style unsigned long
bitmaps.

This introduces a number of helper functions/macros to set and to

The occurrences of an explicit __clear_bit() are intentional, the
drivers were never supposed to change their supported bits on the

switching became broken which I failed to notice
until now.

Function ath10k_mac_vif_chan() reports current
chandef which isn't updated until after
switch_vif_chanctx() is returned from.
Consequently the driver just restarted operation
on channels it was residing already instead of
switching to the new ones.

In practice there's no point in having a copy of
chanctx_conf.

Most of the time the channel pointer (and band
along with it) is accessed and this can't change
after a chanctx is created because switching is
done using explicit chanctx swapping via
switch_vif_chanctx().

The only thing that can change within a
chanctx_conf and is used by the driver is
radar_enabled and channel width. These are however
always accessed in adequate mac80211 callback
context which guarantees safe access to the
chanctx data.

Michal Kazior 44b7d483b7 ath10k: fix inconsistent survey reports
In some cases some channel survey data was
reported incorrect.

Channel info events were expected to come in pairs
without and with COMPLETE flag set respectively
for each channel visit during scan.

The known deviation from this is rule for last
scan chan info and first (next) scan chan info
both have COMPLETE flag set. This was either
programmed with the intent of providing BSS cycle
count info or this is an artefact of firmware scan
state machine. Either way this is useless due to
short wraparound time, wraparound quirks and no
overflow notification.

Survey dumps now include only data gathered during
scan channel visits that can be computed
correctly.

This should improve hostapd ACS a little bit.

Michal Kazior 587f7031f3 ath10k: handle cycle counter wraparound
When QCA988X cycle counter HW register wraps
around it resets to 0x7fffffff instead of 0. All
other cycle counter related registers are divided
by 2 so they never wraparound themselves. QCA61X4
has a uniform CC and it wraparounds in a regular
fashion though.

Worst case wraparound time is approx 24 seconds
(2**31 / 88MHz). Since scan channel visit times
are max 5 seconds (offchannel case) it is
guaranteed there's been at most 1 wraparound and
it is possible to compute survey active time
value. It is, however, impossible to determine the
point at which Rx Clear Count has been divided by
two so it is not reported upon wraparound.

This fixes some occasional incorrect survey data
on QCA988X as some channels (depending on how/when
scan/offchannel requests were requested) would
have approx 24 sec active time which wasn't
actually the case.

This should improve hostapd ACS a little bit.

Johannes Berg 80279fb7ba cfg80211: properly send NL80211_ATTR_DISCONNECTED_BY_AP in disconnect
When we disconnect from the AP, drivers call cfg80211_disconnect().
This doesn't know whether the disconnection was initiated locally
or by the AP though, which can cause problems with the supplicant,
for example with WPS. This issue obviously doesn't show up with any
mac80211 based driver since mac80211 doesn't call this function.

Fix this by requiring drivers to indicate whether the disconnect is
locally generated or not. I've tried to update the drivers, but may
not have gotten the values correct, and some drivers may currently
not be able to report correct values. In case of doubt I left it at
false, which is the current behaviour.

For libertas, make adjustments as indicated by Dan Williams.

changed things like this:

-	if (priv->op_flags & OP_TSF_RESET) {

The problem is that test_bit() takes a bit number and not a mask.  It
means that when we do:

	set_bit(OP_TSF_RESET, &priv->op_flags);

Then it sets the (1 << 6) bit instead of the 6 bit so we are setting a
bit which is past the end of the unsigned long.

Michal Kazior 48f4ca34f3 ath10k: add new 4addr related fw_feature
Some firmware revisions pad 4th hw address in
Native Wifi Rx decap. This is the case with 10.x
and it was assumed that this is true for all
firmware images.

However QCA988X with 999.999.0.636 and QCA61X4
with WLAN.RM.2.0-00088 don't have the padding.
Hence add a feature flag indicating that the
padding isn't present so firmware images can
advertise it appropriately. This way driver will
behave as it was before with old firmware blobs
and doesn't cause any regressions from user
perspective.

Effectively this patch enables QCA988X with
999.999.0.636 and QCA61X4 with WLAN.RM.2.0-00088
to set up client bridging provided user has an
updated firmware blob.

Michal Kazior 77258d409c ath10k: enable pci soc powersaving
By using SOC_WAKE register it is possible to bring
down power consumption of QCA61X4 from 36mA to
16mA when associated and idle.

Currently the sleep threshold/grace period is at a
very conservative value of 60ms.

Contrary to QCA61X4 the QCA988X firmware doesn't
have Rx/beacon filtering available for client mode
and SWBA events are used for beaconing in AP/IBSS
so the SoC needs to be woken up at least every
~100ms in most cases. This means that QCA988X
is at a disadvantage and the power consumption
won't drop as much as for QCA61X4.

Due to putting irq-safe spinlocks on every MMIO
read/write it is expected this can cause a little
performance regression on some systems. I haven't
done any thorough measurements but some of my
tests don't show any extreme degradation.

The patch removes some explicit pci_wake calls
that were added in 320e14b8db51aa ("ath10k: fix
some pci wake/sleep issues"). This is safe because
all MMIO accesses are now wrapped and the device
is woken up automatically if necessary.

David S. Miller b04096ff33 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Four minor merge conflicts:

1) qca_spi.c renamed the local variable used for the SPI device
   from spi_device to spi, meanwhile the spi_set_drvdata() call
   got moved further up in the probe function.

2) Two changes were both adding new members to codel params
   structure, and thus we had overlapping changes to the
   initializer function.

3) 'net' was making a fix to sk_release_kernel() which is
   completely removed in 'net-next'.

4) In net_namespace.c, the rtnl_net_fill() call for GET operations
   had the command value fixed, meanwhile 'net-next' adjusted the
   argument signature a bit.

This also matches example merge resolutions posted by Stephen
Rothwell over the past two days.

Peter Oh 184a394eea ath10k: increase relay buffer size of spectral scan
Spectral scan supported by ath10k has capability to monitor and report
through whole bands and channels, but current buffer size is too small
to save reported spectral scan data.
This results in dropping 5G channel reports at all when dual band card
is used, so that users are not able to analyze spectral environments.
Hence increase the buffer size to fix the problem.

A spectral data size is vary based on the number of bins, so the unit
buffer size, 1140, is chose to minimize relay buffer fragmentation.

The total buffer size is also chose in tradeoff with spectral scan
support vs. kernel memory consumption.
Since theoretical maximum buffer size, 9.5MB, can be consumed with
512 bins in dual bands, we target to cover up to 128 bins for all
channels in dual bands and due to the buffer size limitation,
spectral scan with bin number bigger than 128 needs to be run on
single band each.

This patch introduces two functions to quickly verify the integrity

Note that in case of missing bytes we don't duplicate them, instead

Michal Kazior 45c9abc059 ath10k: implement more versatile set_bitrate_mask
Until now only a single fixed tx rate or nss was
allowed to be set.

The patch attempts to improve this by allowing
most bitrate masks. The limitation is VHT MCS
rates cannot be expressed separately using
existing firmware interfaces and only the
following VHT MCS ranges are supported: none, 0-7,
0-8, and 0-9.

This keeps the old behaviour when requesting
single tx rate or single nss. The new bitrate mask
logic is only applied to other cases that would
return -EINVAL until now.

Depending on firmware revisions some combinations
may crash firmware so use with care, please.

This depends on "ath10k: don't use reassoc flag".
Without it key cache would effectively be
invalidated upon bitrate change leading to
communication being no longer possible.

These work:

  iw wlan0 set bitrates legacy-5 6 12 ht-mcs-5 1 2 3
  iw wlan0 set bitrates legacy-5 ht-mcs-5 7 8 9
  iw wlan0 set bitrates legacy-5 24 ht-mcs-5 vht-mcs-5 1:0-9

These won't work:

  iw wlan0 set bitrates legacy-5 ht-mcs-5 vht-mcs-5 1:0-5
  iw wlan0 set bitrates vht-mcs-5 2:7-9

(note the invalid VHT MCS ranges)

Michal Kazior de57e2c8e1 ath10k: allow loading device specific board files
Some devices differ slightly and require different
board files. If wrong board data is used they
crash or behave incorrectly.

These devices can be differentiated by looking at
PCI subsystem device id. That is the case for
qca61x4 devices at least.

The board specific filename is constructed as:

 board-<bus>-<id>.bin

For PCI in particular it is:

 board-pci-<vendor>:<dev>:<subsys_vendor>:<subsys_dev>.bin

These files are looked in device/hw specific
directories. Hence for Killer 1525 (qca6174 hw2.1)
ath10k will request:

  /lib/firmware/ath10k/QCA6174/hw2.1/board-pci-168c:003e:1a56:1525.bin

To not break any existing setups (e.g. in case
some devices in the wild already have subsys ids)
if a board specific file isn't found a generic one
is used which is the one which would be used until
now. This guarantees that after upgrading a driver
device will not suddenly stop working due to
now-missing specific board file. If this is the
case a "fallback" string is appended to the info
string when driver boots.

Keep in mind this is distinct from cal-pci-*.bin
files which contain full calibration data and MAC
address. Cal data is aimed at systems where
calibration data is stored out of band, e.g. on
nand flash instead of device EEPROM - an approach
taken by some AP/router vendors.

Board files are more of a template and needs some
bits to be filled in by the OTP program using
device EEPROM contents.

One could argue to map subsystem ids to some board
design codename strings instead of using raw ids
when building the board filename. Using a mapping
however would make it a lot more cumbersome and
time consuming (due to how patches propagate over
various kernel trees) to add support for some new
device board designs. Adding a board file is a lot
quicker and doesn't require recompilation.

Peter Oh 7df37f7585 ath10k: use MAC clock rate same as FW uses for survey accuracy
WLAN survey data provides several informative values on each channels
such as noise, active time, transmit time, and etc.
Regarding the channel activity time data, it is reported from firmware
in different form which is number of cycles instead of time itself.
Hence host driver converts it to time unit by dividing it by clock rate
that is used at baseband MAC.

Using difference clock rate from that actual HW is using will result in
inaccurate survey data. For instance, channel active time can be reported
with bigger than 150ms even though we set Dwell time to 150ms.
Therefore set the clock rate to 88000 (88 MHz) which is ath10k baseband
MAC is using.

Janusz Dziedzic 0cd9bc147f ath10k: enable ibss-rsn
With latest additions to the driver it seems
viable to enable support for IBSS-RSN.

It seems to work on QCA988X and 999.999.0.636 but

reason. This may be a firmware quirk or ath10k is
missing something. Nevertheless it makes sense to
finally enable IBSS-RSN in ath10k even if somewhat
handicapped.

QCA6174 firmware doesn't seem to be able to Tx
EAPOL frames at all now (they get stuck in hw
queues for some reason) so it never gets to set
the keys in driver. It's fairly safe to assume that
once this is fixed IBSS-RSN will work with QCA6174

Some time ago there was a weird issue with AP
using wrong multicast keys and generating
corrupted traffic on 10.1 firmware.

Apparently a very similar problem applies for
IBSS-RSN on 999.999.0.636.

ath10k doesn't have IBSS-RSN enabled yet. This
patch is a prerequisite to support it.

Michal Kazior ce90b27128 ath10k: fix multiple key static wep with ibss
Apparently firmware requires both pairwise and
groupwise keys to be installed per-peer for static
WEP in IBSS. This wasn't necessary for AP mode
(and installing both doesn't seem to break AP
mode thus there's no special handling).

Also there seems to be some kind of issue with
mapping tx/rx keys in firmware properly which
resulted in wrong keys being used and broken
communication between devices.

It can be argued the vdev param part is more of a
workaround than a real fix. However I couldn't
figure out how to fix this differently. It works
and isn't super ugly.

Michal Kazior 29a100065e ath10k: change static wep key handling for client mode
mac80211 sets static WEP keys as groupwise while
firmware requires them to be installed twice as
both pairwise and groupwise.

Until now these keys were installed once as
pairwise only and, due to that special handling,
needed additional tricks to support 802.1x as
well.

Without this patch in some cases (when AP and
ath10k client use different default tx keys)
multicast communication was broken.

Michal Kazior 36d8230b7d ath10k: add extra check for frame tracing
Frames are logged via tracing in two slices:
header and payload, separately. This is done for
performance reasons when one wants to, e.g.
analyse metadata only of frames only.

If for some reason device delivered a frame buffer
which was sized below what 802.11 header implied
tracing logic would blow doing an invalid memory
accesses.

I've hit this problem when running IBSS on QCA988X

Peter Oh 26bea13a65 ath: lower JP W53 band DFS detection threshold around 30%
Japan's W53 band requires 50% data traffic during its DFS test,
but WLAN baseband used by ath9k and ath10k is not able to achieve
current threshold rate, 50%, under the data traffic rate.
In other words, HW occasionally fails detecting radar pulses,
so that SW cannot get enough radar reports to achieve the rate.

Separate Japan's DFS pattern from FCC to control PPB threshold.

Currently all the radar detectors use the same threshold rate at
50%, but it's not able to achieve if data traffic rate is higher
than 40% because WLAN baseband used by ath9k and ath10k often fails
detecting radar pulses, so that SW cannot get enough radar reports
to achieve the rate.

Since Japan's W53 band requires 50% data traffic during its DFS
test we need to apply different threshold rate than others on it.
Hence define its own pattern to give flexibility to threshold rate.

Peter Oh 694c0e0a17 ath: support new FCC DFS Radar Type 1
Add support for new FCC DFS rules released on August 14, 2014.
FCC has added a new radar type named Radar Type 1 and original
Radar Type 1 is renamed to Radar Type 0 in consequence.

During the certificate test, Type 1 PRI values are randomly selected
within the range of 518 and 3066 and we divide it to 3 groups based on
practical test result data collected for more than a year.

For about Radar type ID, it does nothing to functionalities.
In other words, even if we re-order the IDs, DFS detection will
work as well, but we give the ID with matching to FCC doc.

By adding this support, the drivers using this DFS function are
able to support both of old and new FCC DFS rules simultaneously
without any other changes.

This fixes worst case warning:

Michal Kazior b4aa539dd8 ath10k: implement tx pause wmi event
qca6174 wmi-tlv firmware defines a new wmi event
for host tx pausing (i.e. stop/wake tx queues).

Map these events to ath10k/mac80211 tx queue
control.

This is important for multi-channel throughput
performance.

Tom Gundersen 6bab2e19c5 cfg80211: pass name_assign_type to rdev_add_virtual_intf()
This will expose in /sys whether the ifname of a device is set by
userspace or generated by the kernel. The latter kind (wlanX, etc)
is not deterministic, so userspace needs to rename these devices
to names that are guaranteed to stay the same between reboots. The
former, however should never be renamed, so userspace needs to be
able to reliably tell the difference.

Similar functionality was introduced for the rtnetlink core in
commit 5517750f05 ("net: rtnetlink - make create_link take name_assign_type")

Since usb bus add extra delay on each request, a command
with read + write requests is too expensive. We can dramtically
reduce usb load by moving this command to firmware.

In my tests, this patch will reduce channel scan time

Kalle Valo 53513c302f ath10k: bump up FW API to 5
Firmware 10.2.4.48-3 now supports management frames over HTT feature and has
ATH10K_FW_FEATURE_HAS_WMI_MGMT_TX. But as 10.2.4 branch has conflicting HTT ids
patch "ath10k: add ATH10K_FW_IE_HTT_OP_VERSION" is needed to fix the issue.
Older ath10k versions don't have support that support and to maintain backwards
compatibility we need bump up the FW API to 5 not break older versions.

Rajkumar Manoharan 8348db2984 ath10k: add ATH10K_FW_IE_HTT_OP_VERSION
Target to host HTT messages are conflicting between 10.x and other
firmware revisions. By maintaining separate HTT T2H tables for each
firmware revisions (main, 10x and tlv) similar to WMI abstraction,
solves the conflicts. Add ATH10K_FW_IE_HTT_OP_VERSION so that the firmware can
advertise the HTT interface to ath10k.

This fix is needed to get management frames over HTT (ie.
ATH10K_FW_FEATURE_HAS_WMI_MGMT_TX disabled) working with 10.2.4.48-2 firmware.
Otherwise there will be unknown htt events and nothing works:

[30087.438343] ath10k_pci 0000:02:00.0: htt event (19) not handled
[30087.448691] ath10k_pci 0000:02:00.0: htt event (19) not handled
[30149.032974] ath10k_pci 0000:02:00.0: htt event (19) not handled

If the firmware does not have ATH10K_FW_IE_HTT_OP_VERSION use the main HTT
interface. That way old firmware images will still work.

Rajkumar Manoharan 9936fa5908 ath10k: move driver state check before setting throttle
Since thermal daemon is unaware of the device state, it might
try to adjust the throttle state when the device is powered down.
So the driver caches the value and will configure it while
powering up the target. The cached value will be programed later
once the device is brought up. In such case, returning error
status is confusing and misleading the user application. Hence
moving the driver state check before sending wmi command to target.

Vladimir Kondratiev c406ea7c74 wil6210: Align Rx frames on 4*n+2 by having SNAP
For the networking code and for hardware network accelerators,
it is better to have IP header 4*n aligned. On the other side,
DMA on Rx path require buffer to be aligned on 4*n as well.
Having 14 bytes of Ethernet header, these 2 alignment
requests are in contradiction.

To solve this, order hardware offload block to not remove
SNAP header. This adds extra 6 bytes between addresses and
ethertype, making it 20 bytes total. This way, both buffer and
IP header are 4*n aligned. Remaining is only to remove SNAP
by shifting addresses 6 bytes. This involves data copying, so
this feature should be disabled unless required by the platform.

Module parameter "rx_align_2" (bool, default - false)
introduced to control this feature. Feature is completely disabled
when parameter is false.
