2017-09-21ath10k: mark PM functions as __maybe_unusedArnd Bergmann

2017-08-31ath10k: configure and enable the wakeup capabilityRyan Hsu
ACPI will rely on device driver to tell it if the device could support wakeup function when system in D3 state. This has caused some platform can't support remote wakeup correctly, because the ACPI wakeup GPE is not enabled, hence registers the .set_wakeup callback to handle it if device supports wakeup.

2017-08-31ath10k: activate user space firmware loading againHauke Mehrtens
In commit 9f5bcfe93315 ("ath10k: silence firmware file probing warnings") the firmware loading was changed from request_firmware() to request_firmware_direct() to silence some warnings in case it fails. request_firmware_direct() directly searches in the file system only and does not send a hotplug event to user space in case it could not find the firmware directly. In LEDE we use a user space script to extract the calibration data from the flash memory which gets triggered by the hotplug event. This way the firmware gets extracted from some vendor specific partition when the driver requests this firmware. This mechanism does not work any more after this change.

2017-08-31ath10k: fix napi_poll budget overflowRyan Hsu
In napi_poll, the budget number is used to control the amount of packets we should handle per poll to balance the resource in the system. In the list of the amsdu packets reception, we check if there is budget count left and handle the complete list of the packets, that it will have chances the very last list will over the budget leftover. So adding one more parameter - budget_left, this would help while traversing the list to avoid handling more than the budget given.

2017-08-08ath10k: fix memory leak in rx ring buffer allocationRakesh Pillai
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.

2017-08-03ath10k: push peer type to target for TDLS peersManikanta Pubbisetty
WMI interface for all the firmwares(except QCA6174) does not include the type of peer(default/bss/tdls) requested during peer creation, therefore target creates a default peer. TDLS implementation on 10.4 firmware requires host to configure the peer type(tdls) for TDLS peers. This patch adds peer type parameter to the existing WMI interface for peer creation to accommodate this requirement. Tested this change on QCA9888(10.4-3.5.1-00018) and QCA988x(10.2.4.70.9-2) with ping tests for AP/STA modes.

Though there is room to accommodate 512 services in wmi service ready event, target uses only first 4-bits of each 32-bit word for advertising wmi services thereby limiting max wmi services to 64. TDLS implementation for 10.4 firmwares introduces new wmi services by making use of remaining unused bits of each 32-bit word, therefore the wmi service mapping in host needs to be extended.

QCA9984 hardware can do 4x4 at 80Mhz, but only 2x2 at 160Mhz. First, report this to user-space by setting the max-tx-speed and max-rx-speed vht capabilities. Second, if the peer rx-speed is configured, and if we are in 160 or 80+80 mode, and the peer rx-speed matches the max speed for 2x2 or 1x1 at 160Mhz (long guard interval), then use that info to set the peer_bw_rxnss_override appropriately. Without this, a 9984 firmware will not use 2x2 ratesets when transmitting to peer (it will be stuck at 1x1), because the firmware would not have configured the rxnss_override.

2017-06-21ath10k: use complete VHT chan width for 160MHz workaroundBen Greear
The ath10k firmware doesn't announce its VHT channel width capabilities in the vht_cap information from the "service ready event" arguments. The driver must therefore check whether the 160MHz short GI bit is set and whether the driver still doesn't set the bits for the 160/80+80 MHz capabilities. The two bits for the channel width are a two bit integer and not two separate bits which cannot be parsed without the knowledge of the other bit. Using IEEE80211_VHT_CAP_SUPP_CHAN_WIDTH_160_80PLUS80MHZ (b10..) as a mask for this task doesn't make any sense. The correct mask for the VHT channel width should be used instead to make this check more readable.

2017-05-31ath10k: go back to using dma_alloc_coherent() for firmware scratch memoryAdrian Chadd
This reverts commit b057886524be ("ath10k: do not use coherent memory for allocated device memory chunks") in 2015 which converted this allocation from dma_map_coherent() to kzalloc() / dma_map_single(). The current problem manifests when using later model NICs with larger (>700KiB) scratch spaces in memory. Although the kzalloc call succeeds, the software IOMMU TLB code (via dma_map_single()) panics because it can't find 700KiB of linear physmem bounce buffers for DMA. Now, this is a bit of a silly failure mode for the dma map API, but it's what we currently have to play with. In these cases, doing kzalloc() works fine, but the dma_map_single() call fails. After chatting with Linus briefly about this, it indeed should be using dma_alloc_coherent() for doing larger device memory allocation that requires some kind of physical address mapping. You're not supposed to be using kzalloc and dma_map_* calls for large memory regions, and I'm guessing not for long-held mappings either. Typically dma mappings should be temporary for DMA, not long held like these. Now, since hopefully the major annoying underlying problem has also been addressed (ie, ath10k is no longer tears down all of these allocations and reallocates them every time the vdevs are brought down) fragmentation should stop being such a touchy issue. If it is though, using dma_alloc_coherent() use gets us access to the CMB APIs too relatively easily and ideally we would be allocating memory early in boot for exactly these reasons.

2017-05-23ath10k: fix reported HT MCS rates with NSS > 1Sven Eckelmann
The QCA4019 firmware 10.4-3.2.1-00050 reports only HT MCS rates between 0-9. But 802.11n MCS rates can be larger than that. For example a 2x2 device can send with up to MCS 15. The firmware encodes the higher MCS rates using the NSS field. The actual calculation is not documented by QCA but it seems like the NSS field can be mapped for HT rates to following MCS offsets: * NSS 1: 0 * NSS 2: 8 * NSS 3: 16 * NSS 4: 24 This offset therefore has to be added for HT rates before they are stored in the rate_info struct.

2017-05-04ath10k: fix out of bounds access to local bufferMichael Mera
During write to debugfs file simulate_fw_crash, fixed-size local buffer 'buf' is accessed and modified at index 'count-1', where 'count' is the size of the write (so potentially out of bounds). This patch fixes this problem. Signed-off-by: Michael Mera <dev@michaelmera.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2017-05-04ath10k: add initial SDIO supportErik Stromdahl
Chipsets like QCA6584 have support for SDIO so add initial SDIO bus support to ath10k. With this patch we have the low level HTC protocol working and it's possible to boot the firmware, but it's still not possible to connect or anything like. More changes are needed for full functionality. For that reason we print during initialisation: WARNING: ath10k SDIO support is incomplete, don't expect anything to work!

2017-05-04ath10k: different fw file name for sdioErik Stromdahl
Since both SDIO based chipsets will use different firmware from the PCIe and AHB chipsets, the fw file name must be different depending on bus type. The new firmware names are: For PCIe and AHB: firmware-<api_version>.bin (same as before) For SDIO: firmware-sdio-<api_version>.bin Signed-off-by: Erik Stromdahl <erik.stromdahl@gmail.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2017-05-04ath10k: htc: ready_ext msg supportErik Stromdahl
Added support for extended ready message. The extended ready message contains the maximum bundle count supported by SDIO chipsets. It is transmitted by SDIO chipset only and replaces the "standard" ready message in this case.

2017-05-04ath10k: htc: refactorizationErik Stromdahl
Code refactorization: Moved the code for ep 0 in ath10k_htc_rx_completion_handler to ath10k_htc_control_rx_complete. This eases the implementation of SDIO/mbox significantly since the ep_rx_complete cb is invoked directly from the SDIO/mbox hif layer. Since the ath10k_htc_control_rx_complete already is present (only containing a warning message) there is no reason for not using it (instead of having a special case for ep 0 in ath10k_htc_rx_completion_handler).

2017-05-04ath10k: htc: move htc ctrl ep connect to htc_initErik Stromdahl
This patch moves the HTC ctrl service connect from htc_wait_target to htc_init. This is done in order to make sure the htc ctrl service is setup properly before hif_start is called. The reason for this is that we want the HTC ctrl service callback to be initialized before the target sends the HTC ready message. The ready message will always be transmitted on endpoint 0 (which is always assigned to the HTC control service) so it makes more sense if HTC control has been connected before the ready message is received. Since the service to pipe mapping is done as a part of the service connect, the get_default_pipe call is redundant and was removed.

2017-05-04ath10k: htc: rx trailer lookahead supportErik Stromdahl
The RX trailer parsing is now capable of parsing lookahead reports. A lookahead contains the first 4 bytes of the next HTC message (that will be read in the next SDIO read operation). Lookaheads are used by the SDIO/mbox HIF layer to determine if the next message is part of a bundle, which endpoint it belongs to and how long it is.
