2014-03-28ath10k: advertise only firmware API 2 filesKalle Valo
We do not really support older firmware API 1 anymore, so better remove MODULE_FIRMWARE() declarations for them and only list for API 2 files. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-03-28ath10k: fix name of target_ps module parameterKalle Valo
The parameter name was ath10k_target_ps, but actually it should be just target_ps. Module parameter names should not use the ath10k_ prefix. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-03-28ath10k: add module parameter to disable cold resetKalle Valo
As cold reset is not reliable with CUS223 boards, make it possible to disable cold reset entirely and only use warm reset. This makes it also easier to debug warm reset problems. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-03-28ath10k: cleanup ath10k_pci_wait_for_target_init()Kalle Valo
ath10k_pci_wait_for_target_init() did really follow the style used elsewhere in ath10k. Use ath10k_pci_read/write() wrappers, simplify the while loop and improve warning messages. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2014-03-28ath10k: unify warning messages in mac.cKalle Valo
Currently there are different styles used for warning messages, unify them to look similar. The style basically is: 1) start with a verb (if possible) 2) lower case letters 3) use plain english as much as possible Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-03-25ath10k: fix rssi and rate reportingJanusz Dziedzic
RSSI and RATES fields are valid only when START_VALID bit is set. So, in current implementation we have to remember/caclulate them when START_VALID and report the same when only END_VALID is set. Currently during heavy traffic we could have: - 10 packets with START_VALID - correct RSSI and RATES - 10 packets with END_VALID - 10 packets with START_VALID - correct RSSI and RATES - 10 packets with END_VALID ... Next using monitor interface we will see: - 10 packets with correct rssi/rates - 10 packets with rssi=-95/rate=6Mbps Signed-off-by: Janusz Dziedzic <janusz.dziedzic@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2014-03-24ath10k: update regulatory domain settings for 10.x firmwareMarek Puzyniak
Regulatory domain settings for firmware 10.x has more options than main firmware, so handle regulatory domain setup separately for both supported firmwares. Fill in additional dfs domain parameter according to current regulatory. This patch does not solve any known bug. Not handled parameter for firmware 10.x was found during code review.

2014-03-24ath10k: add soft/hard firmware crash option to simulate_fw_crashMarek Puzyniak
Command WMI_FORCE_FW_HANG_CMDID is not supported in firmware 10.1. In order to have firmware crash simulation functionality also in firmware 10.1 driver can force firmware crash by performing not allowed operation. Driver can deliberately crash firmware when setting vdev param for vdev id out of range. This patch introduces two keywords to simulate_fw_crash: 'soft' which will cause firmware crash that is recoverable by warm firmware reset but supported only in main firmware. 'hard' which will cause firmware crash recoverable by cold firmware reset, this option works for both firmwares. Commands to trigger firmware soft/hard crash: echo 'soft' > /sys/kernel/debug/ieee80211/phyX/ath10k/simulate_fw_crash echo 'hard' > /sys/kernel/debug/ieee80211/phyX/ath10k/simulate_fw_crash kvalo: remove '\n' before checking the command and simplify how buf is null terminated Signed-off-by: Marek Puzyniak <marek.puzyniak@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2014-03-11ath10k: allow the supported rate change by reassociate peerChun-Yeow Yeoh
IBSS mode requires the changing of supported rate. Do this by reassociate the peer.

2014-02-28ath10k: remove pci completion listMichal Kazior
One of the premises was to guarantee serialized completion handling for upper layers (HTC/WMI/HTT). Since quite some time now it is no longer necessary. The other premise was to batch up tx/rx completions to take advantage of hot caches. However frame tx/rx completion indications come in on a single pipe already so they are already batched up. More meaningful batching is done in HTT itself. This means PCI completion is no longer necessary to keep around. It just wastes memory, cycles and SLOC.

2014-02-28ath10k: reduce htt tx/rx spinlock overheadMichal Kazior
It is inefficient to grab irqsave spinlocks for skb lists for each queue/dequeue action. Using rx_ring.lock and tx_lock allows to use less heavy bh spinlock functions and moving locking upwards allows to toggle spinlocks less often.

2014-02-28ath10k: batch htt tx/rx completionsMichal Kazior
HTT Rx endpoint processes both frame rx indications and frame tx completion indications. Those completions typically come in batches and may be mixed so it makes sense to defer processing hoping to get a bunch of them and take advantage of hot caches.

2014-02-28ath10k: bypass htc for htt tx pathMichal Kazior
Going through full htc tx path for htt tx is a waste of resources. By skipping it it's possible to easily submit scatter-gather to the pci hif for reduced host cpu load and improved performance. The new approach uses dma pool to store the following metadata for each tx request: * msdu fragment list * htc header * htt tx command The htt tx command contains a msdu prefetch. Instead of copying it original mapped msdu address is used to submit a second scatter-gather item to hif to make a complete htt tx command. The htt tx command itself hands over dma mapped pointers to msdus and completion of the command itself doesn't mean the frame has been sent and can be unmapped/freed. This is why htc tx completion is skipped for htt tx as all tx related resources are freed upon htt tx completion indication event (which also implicitly means htt tx command itself was completed). Since now each htt tx request effectively consists of 2 copy engine items CE_HTT_H2T_MSG_SRC_NENTRIES is updated to allow maximum of TARGET_10X_NUM_MSDU_DESC msdus being queued. This keeps the tx path resource management simple. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2014-02-28ath10k: remove DMA mapping wrappersMichal Kazior

2014-02-27ath10k: skip management frames in HTT pathJanusz Dziedzic
After we pass frames with INV_PEER to upper layer in commit 716ae53c56cf ("ath10k: pass frames with invalid peer status to upper layer") we could pass some management frames (in case INVALID_PEER and MGMT_CTRL) twice to upper layer, once via WMI and once via HTT.
