2014-08-27ath10k: dont duplicate service-pipe mappingMichal Kazior
The mapping is already defined in a structure. It makes little sense to duplicate information stored in it within a function. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2014-08-26ath10k: fix fw crash dumpingMichal Kazior
Recent crash dump patches introduced a regression. If debugfs was disabled upon crash user could only see the following: [ 793.880000] ath10k: firmware crashed!

2014-08-25ath10k: flush hif buffers before recoveryMichal Kazior
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.

2014-08-25ath10k: rework posting pci rx buffersMichal Kazior
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.

2014-08-25ath10k: remove early irq handlingMichal Kazior
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. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-08-25ath10k: make sure to really disable irqsMichal Kazior
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.

2014-08-25ath10k: split ce irq/handler setupMichal Kazior

2014-08-14ath10k: unregister spectral before macSimon Wunderlich
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.

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.

2014-08-12ath10k: introduce a stricter scan state machineMichal Kazior
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.

2014-08-04ath10k: add spectral scan featureSimon Wunderlich
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.

2014-08-02ath10k: improve channel switchingMichal Kazior
In some cases during heavy tx vdev stop-start would timeout on vdev synchronization causing traffic to stall for a few seconds.

2014-07-25ath10k: handle attention flags correctly when using A-MSDUJanusz Dziedzic
In case of A-MSDU RX we should check attention flags correctly to be sure we report correct FCS status for A-MSDU subframes. Without a patch we could report A-MSDU subframes with wrong FCS as a correct to the stack, next get a lot of DUP ACK TCP packets. Finally TP drop is seen and this drop depends on FCS errors ratio for A-MSDU frame. Example test case when TP drop is seen: - ath10k configured as an AP - used ath10k station - forced A-MSDU (7 frames) on STA - other traffic on channel (often FCS errors) - monitor iface added on AP - TCP STA -> AP traffic (iperf) a) Iperf logs for case without the patch: echo "1 64" > htt_max_amsdu_ampdu // disable A-MSDU [ ID] Interval Transfer Bandwidth [ 3] 0.0- 5.0 sec 56.6 MBytes 95.0 Mbits/sec [ 3] 5.0-10.0 sec 60.4 MBytes 101 Mbits/sec [ 3] 10.0-15.0 sec 60.2 MBytes 101 Mbits/sec [ 3] 15.0-20.0 sec 60.2 MBytes 101 Mbits/sec [ 3] 20.0-25.0 sec 63.8 MBytes 107 Mbits/sec [ 3] 25.0-30.0 sec 64.9 MBytes 109 Mbits/sec echo "7 64" > htt_max_amsdu_ampdu // set 7 A-MSDU subframes [ 3] 30.0-35.0 sec 40.0 MBytes 67.1 Mbits/sec [ 3] 35.0-40.0 sec 35.9 MBytes 60.2 Mbits/sec [ 3] 40.0-45.0 sec 36.9 MBytes 61.9 Mbits/sec [ 3] 45.0-50.0 sec 37.9 MBytes 63.5 Mbits/sec [ 3] 50.0-55.0 sec 34.5 MBytes 57.9 Mbits/sec [ 3] 55.0-60.0 sec 25.4 MBytes 42.6 Mbits/sec [ 3] 60.0-65.0 sec 48.2 MBytes 81.0 Mbits/sec [ 3] 65.0-70.0 sec 28.8 MBytes 48.2 Mbits/sec [ 3] 70.0-75.0 sec 29.2 MBytes 49.1 Mbits/sec [ 3] 75.0-80.0 sec 22.9 MBytes 38.4 Mbits/sec [ 3] 80.0-85.0 sec 26.4 MBytes 44.2 Mbits/sec [ 3] 85.0-90.0 sec 31.5 MBytes 52.8 Mbits/sec b) Iperf logs for case with patch: echo "1 64" > htt_max_amsdu_ampdu // disable A-MSDU [ 3] local 192.168.12.2 port 57512 connected with 192.168.12.1 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0- 5.0 sec 60.8 MBytes 102 Mbits/sec [ 3] 5.0-10.0 sec 62.2 MBytes 104 Mbits/sec [ 3] 10.0-15.0 sec 60.9 MBytes 102 Mbits/sec echo "7 64" > htt_max_amsdu_ampdu // set 7 A-MSDU subframes [ 3] 15.0-20.0 sec 68.1 MBytes 114 Mbits/sec [ 3] 20.0-25.0 sec 80.5 MBytes 135 Mbits/sec [ 3] 25.0-30.0 sec 83.0 MBytes 139 Mbits/sec [ 3] 30.0-35.0 sec 79.1 MBytes 133 Mbits/sec [ 3] 35.0-40.0 sec 77.1 MBytes 129 Mbits/sec [ 3] 40.0-45.0 sec 77.4 MBytes 130 Mbits/sec Reported-by: Denton Gentry <denton.gentry@gmail.com> Signed-off-by: Janusz Dziedzic <janusz.dziedzic@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
