2024-11-12wifi: ath11k: Fix unexpected return buffer manager error for WCN6750/WCN6855Balaji Pothunoori
The following error messages were encountered while parsing fragmented RX packets for WCN6750/WCN6855: ath11k 17a10040.wifi: invalid return buffer manager 4 This issue arose due to a hardcoded check for HAL_RX_BUF_RBM_SW3_BM introduced in 'commit 71c748b5e01e ("ath11k: Fix unexpected return buffer manager error for QCA6390")' For WCN6750 and WCN6855, the return buffer manager ID should be HAL_RX_BUF_RBM_SW1_BM. The incorrect conditional check caused fragmented packets to be dropped, resulting in the above error log. Fix this by adding a check for HAL_RX_BUF_RBM_SW1_BM.

2021-12-22ath11k: Fix unexpected return buffer manager error for QCA6390Baochen Qiang
We are seeing below error on QCA6390: ... [70211.671189] ath11k_pci 0000:72:00.0: failed to parse rx error in wbm_rel ring desc -22 [70212.696154] ath11k_pci 0000:72:00.0: failed to parse rx error in wbm_rel ring desc -22 [70213.092941] ath11k_pci 0000:72:00.0: failed to parse rx error in wbm_rel ring desc -22 ... The reason is that, with commit 734223d78428 ("ath11k: change return buffer manager for QCA6390"), ath11k expects the return buffer manager (RBM) field of descriptor configured as HAL_RX_BUF_RBM_SW1_BM when parsing error frames from WBM2SW3_RELEASE ring. This is a wrong change cause the RBM field is set as HAL_RX_BUF_RBM_SW3_BM. The same issue also applies to REO2TCL ring though we have not got any error reported. Fix it by changing RBM from HAL_RX_BUF_RBM_SW1_BM to HAL_RX_BUF_RBM_SW3_BM for these two rings.

2021-12-20ath11k: report tx bitrate for iw wlan station dumpWen Gong
HTT_T2H_MSG_TYPE_PPDU_STATS_IND is a message which include the ppdu info, currently it is not report from firmware for ath11k, then the tx bitrate of "iw wlan0 station dump" always show an invalid value "tx bitrate: 6.0 MBit/s". To address the issue, this is to parse the info of tx complete report from firmware and indicate the tx rate to mac80211. After that, "iw wlan0 station dump" show the correct tx bit rate such as: tx bitrate: 78.0 MBit/s MCS 12 tx bitrate: 144.4 MBit/s VHT-MCS 7 short GI VHT-NSS 2 tx bitrate: 286.7 MBit/s HE-MCS 11 HE-NSS 2 HE-GI 0 HE-DCM 0 tx bitrate: 1921.5 MBit/s 160MHz HE-MCS 9 HE-NSS 2 HE-GI 0 HE-DCM 0 Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1 Signed-off-by: Wen Gong <quic_wgong@quicinc.com> Signed-off-by: Kalle Valo <quic_kvalo@quicinc.com> Link: https://lore.kernel.org/r/20211217093722.5739-1-quic_wgong@quicinc.com
2021-12-20ath11k: report rssi of each chain to mac80211 for QCA6390/WCN6855Wen Gong
Command "iw wls1 station dump" does not show each chain's rssi currently. If the rssi of each chain from mon status which parsed in function ath11k_hal_rx_parse_mon_status_tlv() is invalid, then ath11k send wmi cmd WMI_REQUEST_STATS_CMDID with flag WMI_REQUEST_RSSI_PER_CHAIN_STAT to firmware, and parse the rssi of chain in wmi WMI_UPDATE_STATS_EVENTID, then report them to mac80211. WMI_REQUEST_STATS_CMDID is only sent when CONFIG_ATH11K_DEBUGFS is set, it is only called by ath11k_mac_op_sta_statistics(). It does not effect performance and power consumption. Because after STATION connected to AP, it is only called every 6 seconds by NetworkManager in below stack.

Add packet log support for QCA6390, otherwise the data connection will stall within a minute or so. Enable it via debugfs and use trace-cmd to capture the pktlogs. echo 0xffff 1 > /sys/kernel/debug/ath11k/qca6390\ hw2.0/mac0/pktlog_filter The mon status ring doesn't support interrupt so far, so host starts a timer to reap this ring. The timer handler also reaps the rxdma_err_dst_ring in case of monitor mode. As QCA6390 requires bss created ahead of starting vdev, so check vdev_start_delay for monitor mode. For QCA6390, it uses wbm_desc_rel_ring to return descriptors. It also uses rx_refill_buf_ring to fill mon buffer instead of rxdma_mon_buf_ring.

On QCA6390 reg_start and reg_size values are different from IPQ8074 so we need to change the values runtime. As we can't modify a static const variable hw_srng_config directly, instead use it as a template, copy it and modify the copy with correct values.

2020-03-18ath11k: Configure hash based reo destination ring selectionSriram R
Current implementation of pdev based reo destination ring selection is replaced by hash based ring selection so as to ensure all the available rings are utilized for better performance. The 4 reo destination rings are selected by the HW based on the hash value computed from the received packet based on the 5 tuple {ip src/ip dst/src port/dst port/protocol}. Out of the 32 hash values used by the hw, the driver assigns 8 values per reo destination ring to each of the 4 reo destination rings.

2020-03-17ath11k: enable PN offloadManikanta Pubbisetty
Enabling PN checking in the hardware; hardware checks the PN of the received packets and reports the errors to the host for further handling; default action is to drop such packets. TSC (TKIP sequence counter) validation is also offloaded. Hardware validates PN/TSC only for unicast packets; for group addressed packets, PN validation is done in mac80211. PN errors are reported to the driver via WBM RX release ring and can be dumped by using the following command. "cat /sys/kernel/debug/ath11k/soc_rx_stats | grep -i pn" Sample Output: PN check fail: 210 Signed-off-by: Manikanta Pubbisetty <mpubbise@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2019-11-25ath11k: driver for Qualcomm IEEE 802.11ax devicesKalle Valo
ath11k is a new driver for Qualcomm IEEE 802.11ax devices, first supporting only IPQ8074 SoC using the shared memory AHB bus. ath11k uses mac80211 and supports AP, Station and Mesh modes. Even though ath11k has some similar code as with ath10k (especially the WMI layer) it was concluded to be simpler to have a "clean start" for ath11k code base and not try to share the code with ath10k. This makes maintenance easier and avoids major changes in ath10k, which would have significantly increased the risk of regressions in existing setups. Even though the driver is very similar with ath10k but there are major differences as well. The datapath is completely different. ath11k supports multiple MACs, called "soc" in the firmware interface. And there's only one WMI interface to support. Currently ath11k supports only IEEE 802.11ac mode, but patches for 802.11ax are available and they will be submitted after ath11k is accepted to upstream. The firmware images are available from ath11k-firmware repository but they will be also submitted to linux-firmware: https://github.com/kvalo/ath11k-firmware This was tested with firmware version WLAN.HK.2.1.0.1-00629-QCAHKSWPL_SILICONZ-1.
