2017-11-30ath10k: set CTS protection VDEV param only if VDEV is upBartosz Markowski1-8/+43
[ Upstream commit 7cfe0455ee1218add152e986b89b4bb8dbeafcdd ] The cts protection vdev parameter, in new QCA9377 TF2.0 firmware, requires bss peer to be created for the STATION vdev type. bss peer is being allocated by the firmware after vdev_start/_up commands. mac80211 may call the cts protection setup at any time, so the we needs to track the situation and defer the cts configuration to prevent firmware asserts, like below: [00]: 0x05020001 0x000015B3 0x0099ACE2 0x00955B31 [04]: 0x0099ACE2 0x00060730 0x00000004 0x00000000 [08]: 0x0044C754 0x00412C10 0x00000000 0x00409C54 [12]: 0x00000009 0x00000000 0x00952F6C 0x00952F77 [16]: 0x00952CC4 0x00910712 0x00000000 0x00000000 [20]: 0x4099ACE2 0x0040E858 0x00421254 0x004127F4 [24]: 0x8099B9B2 0x0040E8B8 0x00000000 0xC099ACE2 [28]: 0x800B75CB 0x0040E8F8 0x00000007 0x00005008 [32]: 0x809B048A 0x0040E958 0x00000010 0x00433B10 [36]: 0x809AFBBC 0x0040E9A8 0x0042BB74 0x0042BBBC [40]: 0x8091D252 0x0040E9C8 0x0042BBBC 0x00000001 [44]: 0x809FFA45 0x0040EA78 0x0043D3E4 0x0042C2C8 [48]: 0x809FCEF4 0x0040EA98 0x0043D3E4 0x00000001 [52]: 0x80911210 0x0040EAE8 0x00000010 0x004041D0 [56]: 0x80911154 0x0040EB28 0x00400000 0x00000000 Signed-off-by: Bartosz Markowski <bartosz.markowski@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com> Signed-off-by: Sasha Levin <alexander.levin@verizon.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2017-11-30ath10k: fix incorrect txpower set by P2P_DEVICE interfaceRyan Hsu1-3/+4
[ Upstream commit 88407beb1b1462f706a1950a355fd086e1c450b6 ] Ath10k reports the phy capability that supports P2P_DEVICE interface. When we use the P2P supported wpa_supplicant to start connection, it'll create two interfaces, one is wlan0 (vdev_id=0) and one is P2P_DEVICE p2p-dev-wlan0 which is for p2p control channel (vdev_id=1). ath10k_pci mac vdev create 0 (add interface) type 2 subtype 0 ath10k_add_interface: vdev_id: 0, txpower: 0, bss_power: 0 ... ath10k_pci mac vdev create 1 (add interface) type 2 subtype 1 ath10k_add_interface: vdev_id: 1, txpower: 0, bss_power: 0 And the txpower in per vif bss_conf will only be set to valid tx power when the interface is assigned with channel_ctx. But this P2P_DEVICE interface will never be used for any connection, so that the uninitialized bss_conf.txpower=0 is assinged to the arvif->txpower when interface created. Since the txpower configuration is firmware per physical interface. So the smallest txpower of all vifs will be the one limit the tx power of the physical device, that causing the low txpower issue on other active interfaces. wlan0: Limiting TX power to 21 (24 - 3) dBm ath10k_pci mac vdev_id 0 txpower 21 ath10k_mac_txpower_recalc: vdev_id: 1, txpower: 0 ath10k_mac_txpower_recalc: vdev_id: 0, txpower: 21 ath10k_pci mac txpower 0 This issue only happens when we use the wpa_supplicant that supports P2P or if we use the iw tool to create the control P2P_DEVICE interface.

2017-09-14ath10k: fix memory leak in rx ring buffer allocationRakesh Pillai1-6/+6
commit f35a7f91f66af528b3ee1921de16bea31d347ab0 upstream. The rx ring buffers are added to a hash table if firmware support full rx reorder. If the full rx reorder support flag is not set before allocating the rx ring buffers, none of the buffers are added to the hash table. There is a race condition between rx ring refill and rx buffer replenish from napi poll. The interrupts are enabled in hif start, before the rx ring is refilled during init. We replenish buffers from napi poll due to the interrupts which get enabled after hif start. Hence before the entire rx ring is refilled during the init, the napi poll replenishes a few buffers in steps of 100 buffers per attempt. During this rx ring replenish from napi poll, the rx reorder flag has not been set due to which the replenished buffers are not added to the hash table Set the rx full reorder support flag before we allocate the rx ring buffer to avoid the memory leak.

2017-08-07ath10k: fix null deref on wmi-tlv when trying spectral scanMichal Kazior1-0/+6
commit 18ae68fff392e445af3c2d8be9bef8a16e1c72a7 upstream. WMI ops wrappers did not properly check for null function pointers for spectral scan.

2016-06-08ath10k: fix rx_channel during hw reconfigureRajkumar Manoharan1-1/+7
commit 1ce8c1484e80010a6e4b9611c65668ff77556f45 upstream. Upon firmware assert, restart work will be triggered so that mac80211 will reconfigure the driver. An issue is reported that after restart work, survey dump data do not contain in-use (SURVEY_INFO_IN_USE) info for operating channel. During reconfigure, since mac80211 already has valid channel context for given radio, channel context iteration return num_chanctx > 0. Hence rx_channel is always NULL. Fix this by assigning channel context to rx_channel when driver restart is in progress.

2015-10-29ath10k: remove shadow copy of CE descriptors for source ringRajkumar Manoharan3-33/+0
For the messages from host to target, shadow copy of CE descriptors are maintained in source ring. Before writing actual CE descriptor, first shadow copy is filled and then it is copied to CE address space. To optimize in download path and to reduce d-cache pressure, removing shadow copy of CE descriptors. This will also reduce driver memory consumption by 33KB during on device probing.

2015-10-29ath10k: cleanup copy engine send completionRajkumar Manoharan3-50/+12
The physical address necessary to unmap DMA ('bufferp') is stored in ath10k_skb_cb as 'paddr'. ath10k doesn't rely on the meta/transfer_id when handling send completion (htc ep id is stored in sk_buff control buffer). So the unused output arguments {bufferp, nbytesp and transfer_idp} are removed from CE send completion. This change is needed before removing the shadow copy of copy engine (CE) descriptors in follow up patch.

Currently to avoid uncached memory access while filling up copy engine descriptors, shadow descriptors are used. This can be optimized further by removing shadow descriptors. To achieve that first shadow ring dependency in ce_send is removed by creating local copy of the descriptor on stack and make a one-shot copy into the "uncached" descriptor.

2015-10-28ath10k: enable adaptive CCAMaharaja6-0/+85
European Union has made it mandatory that all devices working in 2.4 GHz has to adhere to the ETSI specification (ETSI EN 300 328 V1.9.1) beginnig this year. The standard basically speaks about interferences in 2.4Ghz band. For example, when 802.11 device detects interference, TX must be stopped as long as interference is present. Adaptive CCA is a feature, when enabled the device learns from the environment and configures CCA levels adaptively. This will improve detecting interferences and the device can stop trasmissions till the interference is present eventually leading to good performances in varying interference conditions. The patch includes code for enabling adaptive CCA for 10.2.4 firmware on QCA988X.

2015-10-19ath10k: disable PCI PS for QCA988X and QCA99X0Anilkumar Kolli2-1/+88
This patch disables PCI PS for QCA988X and QCA99X0, Since PCI PS is validated for QCA6174, let it be enabled only for QCA6174. It would be better to execute PCI PS related functions only for the supported devices. PCI time out issue is observed with QCA99X0 on x86 platform, We will disable PCI PS for QCA988X and QCA99X0 until PCI PS is properly implemented. Taking and releasing ps_lock is causing higher CPU consumption. Michal Kazior suggested ps_lock overhead to be reworked so that ath10k_pci_wake/sleep functions are called less often, i.e. move the powersave logic up (only during irq handling, tx path, submitting fw commands) but that's a bigger change and can be implemented later.

2015-10-16ath10k: configure copy engine 5 for HTT messagesRajkumar Manoharan1-11/+59
Currently target to host (T2H) HTT messages are received at copy engine 1. These messages are processed by HTC layer in both host and target. To avoid HTC level processing overhead in both host and target, the unused copy engine 5 is being used for receiving HTT T2H messages. This will speedup the receive data processing as well as htt tx completion. Hence host and target copy engine configuration tables are updated to enable CE5 pipe. The in-direction HTT mapping is now pointing to CE5 for all HTT T2H. Moreover HTT send completion messages are polled from HTC handler as CE 4 is not interrupt-driven. For faster tx completion, CE4 polling needs to be done whenever CE pipe which transports HTT Rx (target->host) is processed. This avoids overhead of polling HTT messages from HTC layer. Servicing CE 4 faster is helping to solve "failed to transmit packet, dropping: -105".

2015-10-14ath10k: add board 2 API supportManikanta Pubbisetty5-49/+250
QCA6174 needs different board files based on board type. To make it easier to distribute multiple board files and automatically choose correct board file create a simple TLV file format following the same principles as with FW IEs. The file is named board-2.bin and contain multiple board files. Each board file then can have multiple names. ath10k searches for file board-N.bin (where N is the interface version number for the board file, just like we for firmware files) in /lib/firmware/*, for example for qca99x0 it will try to find it here: /lib/firmware/ath10k/QCA99X0/hw2.0/board-2.bin If ath10k doesn't find board-2.bin then it will fallback to the old board.bin file. This patch adds a simple name scheme using pci device id which for now will be used by qca6174: bus=%s,vendor=%04x,device=%04x,subsystem-vendor=%04x,subsystem-device=%04x This removes the old method of having subsystem ids in ar->spec_board_id and using that in the board file name.
