Hi, Possibly related (maybe not the same problem but the solution might help): System IMX6UL + QCA9377 module from TechNexion, kernel 5.10 ath10k_sdio dropping packets. Normally it works, but under high load it starts dropping packets. Discovered this when streaming sensor data. E.g when flood pinging the gateway: ping -f 192.168.10.1 [ 3157.382786] ath10k_sdio mmc1:0001:1: failed to transmit packet, dropping: -12 [ 3157.390063] ath10k_sdio mmc1:0001:1: failed to submit frame: -12 [ 3157.396158] ath10k_sdio mmc1:0001:1: failed to push frame: -12 [ 3157.492433] ath10k_sdio mmc1:0001:1: failed to transmit packet, dropping: -12 [ 3157.499728] ath10k_sdio mmc1:0001:1: failed to submit frame: -12 [ 3157.505753] ath10k_sdio mmc1:0001:1: failed to push frame: -12 (then locks up the ssh terminal). Solution in my case was to revert to a custom(?) qca driver: git clone https://github.com/TechNexion/qcacld-2.0.git cd qcacld-2.0 (expects a cross compiler toolchain to be installed and configured, as well as the kernel source to be at ~/os/linux-tn-imx): KERNEL_SRC=~/os/linux-tn-imx CONFIG_CLD_HL_SDIO_CORE=y TARGET_BUILD_VARIANT=user make -j$(nproc) KERNEL_SRC=~/os/linux-tn-imx INSTALL_MOD_PATH=~/os/linux-tn-imx_modules make modules_install When copied to the target and set up, lsmod should show similar to: Module Size Used by wlan 3764224 0 imx_sdma 28672 8 Best regards Patrik -- Electrical Engineering J2 Holding AB (http://www.j-2.se) Skype: patrik.arven.j2 Cell: +46 (0)702 780460 (GMT+1, 8:00-20:00, Calls from withheld/hidden numbers will not be answered) ----- Ursprungligt meddelande ----- Från: "Fabio Estevam" <festevam@xxxxxxxxx> Till: kvalo@xxxxxxxxxx Kopia: "linux-wireless" <linux-wireless@xxxxxxxxxxxxxxx>, ath10k@xxxxxxxxxxxxxxxxxxx, "Bough Chen" <haibo.chen@xxxxxxx>, "Kevin Groeneveld" <KGroeneveld@xxxxxxxxxxxx>, "Jakub Kicinski" <kuba@xxxxxxxxxx> Skickat: torsdag, 15 dec 2022 4:07:38 Ämne: ath10k: IRQ timeout after AP-STA-POLL-OK Hi, On an imx6dl-pico board with a QCA9377 connected via SDIO, we see very rarely the following error: mmc1: Timeout waiting for hardware interrupt. which happens right after an AP-STA-POLL-OK event. mmc1 is the eMMC port connected to the QCA9377. The QCA9377 operates in AP mode. Since the error is difficult to reproduce, we found a way to accelerate its occurrence and it consists of passing a short ap_max_inactivity value into the hostapd conf file, such as ap_max_inactivity=3. This makes AP-STA-POLL-OK happen more frequently. The full kernel logs are shown below. The mmc timeouts always happen right after an AP-STA-POLL-OK event and AP-STA-POLL-OK always happens after the fifth connection/disconnection. Originally the error was reported on a 5.10 kernel, but I have also reproduced the issue on 6.1. I appreciate it if anyone could provide any suggestions.
