As the exisiting CE configurations are defined in global, there are the chances of QCA99X0 family chipsets CE configurations are getting changed by the ath10k_pci_override_ce_config() function. The override will be hit and CE5 configurations will be changed, when the user bring up the QCA99X0 chipsets along with QCA6174 or QCA9377 chipset. (Bring up QCA99X0 family chipsets after QCA6174 or QCA9377). Hence, fixing this issue by moving the global CE configuration to radio specific CE configuration.

In Multi-AP VAP scenario with frequent interface up-down, there is a chance that ath11k_mgmt_over_wmi_tx_work() will dequeue a skb corresponding to currently deleted/stopped vdev. FW will assert on receiving mgmt_tx_wmi cmd for already deleted vdev. Hence adding validation checks for arvif present on the corresponding ar before sending mgmt_tx_wmi cmd. Signed-off-by:

For SDIO chip, its rx indication is struct htt_rx_indication_hl, which does not include the bitrate info as well as PCIe, for PCIe, it use function ath10k_htt_rx_h_rates to parse the bitrate info in struct rx_ppdu_start and then report it to mac80211 via ieee80211_rx_status. SDIO does not have the same info as PCIe, then iw command can not get the rx bitrate by "iw wlan0 station dump". for example, it always show 6.0 MBit/s localhost ~ # iw wlan0 link Connected to 3c:28:6d:96:fd:69 (on wlan0) SSID: kukui_test freq: 5180 RX: 111800 bytes (595 packets) TX: 35419 bytes (202 packets) signal: -41 dBm rx bitrate: 6.0 MBit/s This patch is to send WMI_TLV_REQUEST_PEER_STATS_INFO_CMDID to firmware for ath10k_sta_statistics and save the rx bitrate for WMI event WMI_TLV_PEER_STATS_INFO_EVENTID.

ADC & I/Q calibrations could take infinite time to comple, since they depend on received frames. In particular the I/Q mismatch calibration requires receiving of OFDM frames for completion. But in the 2.4GHz band, a station could receive only CCK frames for a very long time. And while we wait for the completion of one of the mentioned calibrations, the NF calibration is blocked. Moreover, in some environments, I/Q calibration is unable to complete until a correct noise calibration will be performed due to AGC behaviour. In order to avoid delaying NF calibration on forever, limit the maximum duration of ADCs & I/Q calibrations. If the calibration is not completed within the maximum time, it will be interrupted and a next calibration will be performed. The code that selects the next calibration has been reworked to the loop so incompleted calibration will be respinned later. Ð maximum calibration time of 30 seconds was selected to give the calibration enough time to complete and to not interfere with the long (NF) calibration. Run tested with AR9220. Signed-off-by:

Previously after the calibration validity period is over, calibrations are invalidated in a one at time manner. So, for AR9002 family, which has three calibrations, the full recalibration interval becomes 3 x ATH_RESTART_CALINTERVAL. And each next calibration will be separated by the ATH_RESTART_CALINTERVAL time from a previous one. It seems like it is better to do whole recalibration at once. Also, this change makes the driver behaviour a little simpler. So, invalidate all calibrations at once at the end of the calibration validity interval. This change affects only AR9002 chips family, since the AR9003 utilize only a single calibration. Signed-off-by:

NF calibration and other elements of long calibration are usually faster than ADCs & I/Q calibrations due to independence of receiption of the OFDM signal. Moreover sometime I/Q calibration can not be completed at all without preceding NF calibration. This is due to AGC, which has a habit to block a weak signal without regular NF calibration. Thus, we do not need to deferr the long calibration forever. So, if the long calibration is requested, then deferr the ADCs & I/Q calibration(s) and run the longcal (the NF calibration in particular) to obtain fresh noise data. Run tested with AR9220.

Each of AGC & I/Q calibrations can take a long time. Long calibration and NF calibration in particular are forbiden for parallel run with ADC & I/Q calibrations. So, the chip could not be ready to perform the long calibration at the time of request. And a request to perform the long calibration may be lost. In order to fix this, preserve the long calibration request as a calibration state flag and restore the long calibration request each time the calibration function is called again (i.e. on each subsequent ivocation of the short calibration). This feature will be twice useful after the next change, which will make it possible to start the long calibration before all ADCs & I/Q calibrations are completed. Run tested with AR9220.

ADC calibration is only required for a 80 MHz sampling rate (i.e. for 40 MHz channels), when the chip utilizes the pair of ADCs in interleved mode. Calibration on a 20 MHz channel will never be completed. Previous channel check is trying to exclude all channels where the calibration will get stuck. It effectively blocks the calibration run for HT20 channels, but fails to exclude 20 MHz channels without HT (e.g. legacy mode channels). Fix this issue by reworking the channel check to explicitly allow ADCs gain & DC offset calibrations for HT40 channels only. Also update the complicated comment to make it clear that these calibrations are for multi-ADC mode only. Stuck ADCs calibration blocks the NF calibration, what could make it impossible to work in a noisy evironment: too big Rx attentuation, invalid RSSI value, etc. So this change is actually more of a NF calibration fix rather then the ADC calibration fix. Run tested with AR9220. Signed-off-by:

When tx complete is disabled, all tx status will be set with status HTT_TX_COMPL_STATE_ACK and indicate to mac80211 by ieee80211_tx_status, then it does not have the statistics for retries and failed packets. count of tx retries and tx failed of command "iw wlan0 station dump" are both 0. If tx complete is not disabled, then firmware report the tx status and ath10k indicate the status to mac80211, then mac80211 save the statistics and command "iw wlan0 station dump" show them. for example: localhost ~ # iw dev wlan0 station dump Station 3c:28:6d:96:fd:69 (on wlan0) inactive time: 5 ms rx bytes: 1325012 rx packets: 6477 tx bytes: 85264 tx packets: 518 tx retries: 0 tx failed: 0 This patch only effect chips with tx complete disabled, e.g. SDIO. with this patch, output of command "iw dev wlan0 station dump": Station c4:04:15:5d:97:22 (on wlan0) inactive time: 608 ms rx bytes: 180366 rx packets: 991 tx bytes: 98765577 tx packets: 64624 tx retries: 14682 tx failed: 47086 Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00042.

When run command "iw dev wlan0 station dump", the rx duration is 0. When firmware indicate WMI_UPDATE_STATS_EVENTID, extended flag of statsis not set by default, so firmware do not report rx duration. one sample: localhost # iw wlan0 station dump Station c4:04:15:5d:97:22 (on wlan0) inactive time: 48 ms rx bytes: 21670 rx packets: 147 tx bytes: 11529 tx packets: 100 tx retries: 88 tx failed: 36 beacon loss: 1 beacon rx: 31 rx drop misc: 47 signal: -72 [-74, -75] dBm signal avg: -71 [-74, -75] dBm beacon signal avg: -71 dBm tx bitrate: 54.0 MBit/s MCS 3 40MHz rx bitrate: 1.0 MBit/s rx duration: 0 us This patch enable firmware's extened flag of stats by setting flag WMI_TLV_STAT_PEER_EXTD of ar->fw_stats_req_mask which is set in ath10k_core_init_firmware_features via WMI_REQUEST_STATS_CMDID. After apply this patch, rx duration show value with the command: Station c4:04:15:5d:97:22 (on wlan0) inactive time: 883 ms rx bytes: 44289 rx packets: 265 tx bytes: 10838 tx packets: 93 tx retries: 899 tx failed: 103 beacon loss: 0 beacon rx: 78 rx drop misc: 46 signal: -71 [-74, -76] dBm signal avg: -70 [-74, -76] dBm beacon signal avg: -70 dBm tx bitrate: 54.0 MBit/s MCS 3 40MHz rx bitrate: 1.0 MBit/s rx duration: 358004 us This patch do not have side effect for all chips, because function ath10k_debug_fw_stats_request is already exported to debugfs "fw_stats" and WMI_REQUEST_STATS_CMDID is safely sent after condition checked by ath10k_peer_stats_enabled in ath10k_sta_statistics.

we are sending the reo flush command for the deleted peer tid after the ageout period reaches 1 second. This handling causes reo ring get full when more than 128 clients are disconnected continuously. so added the count for flush list and reo flush command is triggered after the list count reaches the threshold value, it is configured as 64 (half of the reo ring). This will avoid the situation where reo ring get full. Signed-off-by:

When station connected to AP, and run TX traffic such as TCP/UDP, and system enter suspend state, then mac80211 call ath10k_flush with set drop flag, recently it only send wmi peer flush to firmware and firmware will flush all pending TX packets, for PCIe, firmware will indicate the TX packets status to ath10k, and then ath10k indicate to mac80211 TX complete with the status, then all the packets has been flushed at this moment. For SDIO chip, it is different, its TX complete indication is disabled by default, and it has a tx queue in ath10k, and its tx credit control is enabled, total tx credit is 96, when its credit is not sufficient, then the packets will buffered in the tx queue of ath10k, max packets is TARGET_TLV_NUM_MSDU_DESC_HL which is 1024, for SDIO, when mac80211 call ath10k_flush with set drop flag, maybe it have pending packets in tx queue of ath10k, and if it does not have sufficient tx credit, the packets will stay in queue untill tx credit report from firmware, if it is a noisy environment, tx speed is low and the tx credit report from firmware will delay more time, then the num_pending_tx will remain > 0 untill all packets send to firmware. After the 1st ath10k_flush, mac80211 will call the 2nd ath10k_flush without set drop flag immediately, then it will call to ath10k_mac_wait_tx_complete, and it wait untill num_pending_tx become to 0, in noisy environment, it is esay to wait about near 5 seconds, then it cause the suspend take long time. 1st and 2nd callstack of ath10k_flush [ 303.740427] ath10k_sdio mmc1:0001:1: ath10k_flush

The default credit size is 1792 bytes, but the IP mtu is 1500 bytes, then it has about 290 bytes's waste for each data packet on sdio transfer path for TX bundle, it will reduce the transmission utilization ratio for data packet. This patch enable the small credit size in firmware, firmware will use the new credit size 1556 bytes, it will increase the transmission utilization ratio for data packet on TX patch. It results in significant performance improvement on TX path. This patch only effect sdio chip, it will not effect PCI, SNOC etc. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00017-QCARMSWP-1. Signed-off-by:

The transmission utilization ratio for sdio bus for small packet is slow, because the space and time cost for sdio bus is same for large length packet and small length packet. So the speed of data for large length packet is higher than small length. Test result of different length of data: data packet(byte) cost time(us) calculated rate(Mbps) 256 28 73 512 33 124 1024 35 234 1792 45 318 14336 168 682 28672 333 688 57344 660 695 This patch change the TX packet from single packet to a large length bundle packet, max size is 32, it results in significant performance improvement on TX path. Also there's a fourth thread "ath10k_tx_complete_wq" added to ath10k as it improves TCP RX throughput (values in Mbps): TCP-RX TCP-TX UDP-RX UDP-TX use workqueue_tx_complete 423 357 448 412 change it to ar->workqueue 410 360 449 414 change it to ar->workqueue_aux 405 339 446 401 This patch only effect sdio chip, it will not effect PCI, SNOC etc. It only enable bundle for sdio chip.

This patch is to set register to allow the mbox enter sleep status if it does not have tx traffic and wakeup it if tx traffic arrive. After mbox enter sleep status, the soc will enter sleep status by firmware, this will save power. The power consume drops from about 90mW to about 10mW with this patch. This patch only effect sdio chip. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00029. Signed-off-by:

IPQ8074 HW supports three TCL rings for tx. Currently these rings are mapped based on the Access categories, viz. VO, VI, BE, BK. In case, one of the traffic type dominates, then it could stress the same tcl rings. Rather, it would be optimal to make use of all the rings in a round robin fashion irrespective of the traffic type so that the load could be evenly distributed among all the rings. Also, in case the selected ring is busy or full, a retry mechanism is used to ensure other available ring is selected without dropping the packet. In SMP systems, this change avoids a single CPU from getting hogged when heavy traffic of same category is transmitted. The tx completion interrupts corresponding to the used tcl ring would be more which causes the assigned CPU to get hogged. Distribution of tx packets to different tcl rings helps balance this load.

After setting fixed vht-rate if new station is trying to assoc with mu_bfee cap, or if a sta is already connected with mu_bfee cap then set the fixed vht-rate and reconnecting the sta, FW assert is happening. So to avoid this, reset the MU_BEAMFORMEE bit in vht->caps, if mcs_index is invalid for nss 1. Signed-off-by:

During RX, accessing the reo dest ring descriptor directly is consuming a lot of CPU cycles. Accessing the descriptor after copying it locally has improved CPU usage by around ~10-15% while measuring throughput in RX DBTC test cases(all radios are involved in the throughput measurement).
