Whenever htt rx indication i.e target to host messages are received on rx copy engine (CE5), the message will be freed after processing the response. Then CE 5 will be refilled with new descriptors at post rx processing. This memory alloc and free operations can be avoided by reusing the same descriptors. During CE pipe allocation, full ring is not initialized i.e n-1 entries are filled up. So for CE 5 full ring should be filled up to reuse descriptors. Moreover CE 5 write index will be updated in single shot instead of incremental access. This could avoid multiple pci_write and ce_ring access. From experiments, It improves CPU usage by ~3% in IPQ4019 platform. Signed-off-by: NRajkumar Manoharan <rmanohar@qti.qualcomm.com> Signed-off-by: NKalle Valo <kvalo@qca.qualcomm.com>

The physical address necessary to unmap DMA ('bufferp') is stored in ath10k_skb_cb as 'paddr'. For diag register read and write operations, 'paddr' is stored in transfer context. ath10k doesn't rely on the meta/transfer_id. So the unused output arguments {bufferp, nbytesp and transfer_idp} are removed from CE recv_next completion.

Except qca61x4 family chips (qca6164, qca6174), copy engine 5 is used for receiving target to host htt messages. In follow up patch, CE5 descriptors will be reused. In such case, same API can not be used as htc layer callback where the response messages will be freed at the end. Hence register new API for HTC layer that free up received message and keep the message handler common for both HTC and HIF layers.

In follow up patch, htt rx descriptors will be reused instead of dealloc and refill. To achieve that htt rx indication messages should not be deferred and should be processed in pci tasklet itself. Also from rx indication message, mpdu_count alone is used. So it is maintained as atomic variable and all rx amsdu handlers are done processed from txrx tasklet. This change get rid of rx_compl_q usage. Signed-off-by: NRajkumar Manoharan <rmanohar@qti.qualcomm.com> Signed-off-by: NKalle Valo <kvalo@qca.qualcomm.com>

Make amsdu handlers (i.e amsdu_pop and rx_h_handler) common to both rx_ind and frag_ind htt events.

Provide a debugfs entry to enable/ disable Peer Stats feature. Peer Stats feature is for developers/users who are more interested in studying in Rx/Tx stats with multiple clients connected, hence disable this by default. Enabling this feature by default results in unneccessary processing of Peer Stats event for every 500ms and updating peer_stats list (allocating memory) and cleaning it up ifexceeds the higher limit and this can be an unnecessary overhead during long run stress testing.

qca4019 calibration data is stored in the host memory and it's mandatory to download it even before reading board id and chip id from the target. Also, there is a need to execute otp (download and run) twice, one after cal data download and another one after board data download. Existing cal data file name 'cal-<bus>-<id>.bin' and device tree entry 'qcom,ath10k-calibration-data' used in ath10k has assumption that it carries other data (like board data) also along with the calibration data. But, qca4019 cal data contains pure calibration data (doesn't include any other info). So, using existing same cal file name and DT entry in qca4019 case would alter the purpose of it. To avoid this, new cal file name 'pre-cal-<bus>-<id>.bin' and new device tree entry name 'qcom,ath10k-pre-calibration-data are introduced. Overall qca4019's firmware download sequence would look like, 1) Download cal data (either from a file or device tree entry) at the address specified by target in the host interest area member "hi_board_data". 2) Download otp and run with 0x10 (PARAM_GET_EEPROM_BOARD_ID) as a argument. At this point, otp will take back up of downloaded cal data content in another location in the target and return valid board id and chip id to the host. 3) Download board data at the address specified by target in host interest area member "hi_board_data". 4) Download otp and run with 0x10000 (PARAM_FLASH_SECTION_ALL) as a argument. Now otp will apply cal data content from it's backup on top of board data download in step 3 and prepare final data base. 5) Download code swap and athwlan binary content. Above sequences are implemented (step 1 to step 4) in the name of pre calibration configuration. Signed-off-by: NRaja Mani <rmani@qti.qualcomm.com> Signed-off-by: NKalle Valo <kvalo@qca.qualcomm.com>

ath10k_download_cal_dt() compares obtained cal data content length against QCA988X_CAL_DATA_LEN (2116 bytes). It was written by keeping qca988x in mind. In fact, cal data length is more chip specific. To make ath10k_download_cal_dt() more generic and reusable for other chipsets (like qca4019), cal data length is moved to hw_params.

Both ath10k_download_cal_file() and ath10k_download_cal_dt() uses hard coded file pointer (ar->cal_file) and device tree entry (qcom,ath10k-calibration-data) respectively to get calibration data content. There is a need to use those two functions in qca4019 calibration download sequence with different file pointer and device tree entry name. Modify those two functions to take cal data location as an argument. So that it can serve the purpose for other file pointer and device tree entry. This is just preparation before adding actual qca4019 calibration download sequence. No functional changes.

Frames that are transmitted via MGMT_TX are using reserved descriptor slots in firmware. This limitation is for the htt_mgmt_tx path itself, not for mgmt frames per se. In 16 MBSSID scenario, these reserved slots will be easy exhausted due to frequent probe responses. So for 10.4 based solutions, probe responses are limited by a threshold (24). management tx path is separate for all except tlv based solutions. Since tlv solutions (qca6174 & qca9377) do not support 16 AP interfaces, it is safe to move management descriptor limitation check under mgmt_tx function. Though CPU improvement is negligible, unlikely conditions or never hit conditions in hot path can be avoided on data transmission.

Whenever firmware is configuring operating channel during scan or home channel, channel change event will be indicated to host. In some cases (device probe/ last vdev down), target will be configured to default channel whereas host is unaware of target's operating channel. This leads to packet drop due to unknown channel and kernel log will be filled up with "no channel configured; ignoring frame(s)!". Fix that by handling HTT_T2H_MSG_TYPE_CHAN_CHANGE event.

The number of HTT Tx descriptors and qcache peer limit aren't hw-specific. In fact they are firmware specific and should not be placed in hw_params. The QCA4019 limits were submitted with the peer flow control firmware only and to my understanding there's no non-peer-flow-ctrl QCA4019 firmware. However QCA99X0 is planned to run firmware supporting the feature as well. Therefore this patch enables QCA99X0 to use 2500 tx descriptors whenever possible instead of just 1424.

The current/old tx path design was that host, at its own leisure, pushed tx frames to the device. For HTT there was ~1000-1400 msdu queue depth. After reaching that limit the driver would request mac80211 to stop queues. There was little control over what packets got in there as far as DA/RA was considered so it was rather easy to starve per-station traffic flows. With MU-MIMO this became a significant problem because the queue depth was insufficient to buffer frames from multiple clients (which could have different signal quality and capabilities) in an efficient fashion. Hence the new tx path in 10.4 was introduced: a pull-push mode. Firmware and host can share tx queue state via DMA. The state is logically a 2 dimensional array addressed via peer_id+tid pair. Each entry is a counter (either number of bytes or packets. Host keeps it updated and firmware uses it for scheduling Tx pull requests to host. This allows MU-MIMO to become a lot more effective with 10+ clients. Signed-off-by: NMichal Kazior <michal.kazior@tieto.com> Signed-off-by: NKalle Valo <kvalo@qca.qualcomm.com>

The pull-push functionality of 10.4 will be based on peer_id and tid. These will need to be mapped, eventually, to ieee80211_txq to be used with ieee80211_tx_dequeue(). Iterating over existing stations every time peer_id needs to be mapped to a station would be inefficient wrt CPU time. The new firmware, which will be the only user of the code flow-wise, will guarantee to use low peer_ids first so despite peer_map's apparent huge size d-cache thrashing should not be a problem.

Tx pending counter logic assumed that the sk_buff is already known and hence was performed in HTT functions themselves. However, for the sake of future wake_tx_queue() usage the driver must be able to tell whether it can submit more frames to firmware before it dequeues frame from ieee80211_txq (and thus long before HTT Tx functions are called) because once a frame is dequeued it cannot be requeud back to mac80211.
