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:

sdio chip use DMA buffer to receive TX packet from ath10k, and it has limitation of each buffer, if the packet size exceed the credit size, it will trigger error in firmware. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00017-QCARMSWP-1. Signed-off-by:

The driver is allowing the invalid tx/rx chainmask configuration (other than 1,3,7,15) set by the user. It causes the firmware crash due to the invalid chainmask values. Hence, reject the invalid chainmask values in the driver by not sending the pdev set command to the firmware. Tested hardware: QCA9888 Tested firmware: 10.4-3.10-00047 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.

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.

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.

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.

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).

Add the pdev index information in the peer object to validate the peer creation. Ignore the peer creation request, if the given MAC address is already present in the peer list with same radio. If we allow the peer creation in above scenario, FW assert will happen. Above scenario occurred in two cases, where Multiple AP VAP created in the same radio. 1. when testing tool sends association request to two AP with same MAC address 2. when a station do roaming from one AP VAP to another AP VAP.

This sorts the actual field names too, potentially causing even more chaos and confusion at merge time if you have edited the MAINTAINERS file. But the end result is a more consistent layout, and hopefully it's a one-time pain minimized by doing this just before the -rc1 release.

They are all supposed to be sorted, but people who add new entries don't always know the alphabet. Plus sometimes the entry names get edited, and people don't then re-order the entry. Let's see how painful this will be for merging purposes (the MAINTAINERS file is often edited in various different trees), but Joe claims there's relatively few patches in -next that touch this, and doing it just before -rc1 is likely the best time. Fingers crossed. This was scripted with /scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS but then I also ended up manually upper-casing a few entry names that stood out when looking at the end result.
