2024-11-19wifi: ath9k: Add RX inactivity detection and reset chip when it occursToke Høiland-Jørgensen5-2/+36
Some ath9k chips can, seemingly at random, end up in a state which can be described as "deaf". No or nearly no interrupts are generated anymore for incoming packets. Existing links either break down after a while and new links will not be established. The circumstances leading to this "deafness" is still unclear, but some particular chips (especially 2-stream 11n SoCs, but also others) can go 'deaf' when running AP or mesh (or both) after some time. It's probably a hardware issue, and doing a channel scan to trigger a chip reset (which one normally can't do on an AP interface) recovers the hardware. The only way the driver can detect this state, is by detecting if there has been no RX activity for a while. In this case we can proactively reset the chip (which only takes a small number of milliseconds, so shouldn't interrupt things too much if it has been idle for several seconds), which functions as a workaround. OpenWrt, and various derivatives, have been carrying versions of this workaround for years, that were never upstreamed. One version[0], written by Felix Fietkau, used a simple counter and only reset if there was precisely zero RX activity for a long period of time. This had the problem that in some cases a small number of interrupts would appear even if the device was otherwise not responsive. For this reason, another version[1], written by Simon Wunderlich and Sven Eckelmann, used a time-based approach to calculate the average number of RX interrupts over a longer (four-second) interval, and reset the chip when seeing less than one interrupt per second over this period. However, that version relied on debugfs counters to keep track of the number of interrupts, which means it didn't work at all if debugfs was not enabled. This patch unifies the two versions: it uses the same approach as Felix' patch to count the number of RX handler invocations, but uses the same time-based windowing approach as Simon and Sven's patch to still handle the case where occasional interrupts appear but the device is otherwise deaf. Since this is based on ideas by all three people, but not actually directly derived from any of the patches, I'm including Suggested-by tags from Simon, Sven and Felix below, which should hopefully serve as proper credit.

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.

Add changes to add the link vdevs dynamically whenever a channel is assigned from mac80211 for a link vdev. During vdev create, update ML address of the vdev to firmware using the new WMI parameter (WMI_TAG_MLO_VDEV_CREATE_PARAMS). During vdev start, notify the firmware that this link vdev is newly added and also indicate all its known partners so that the firmware can take necessary actions to internally update the partners on the new link being added.

2024-11-06wifi: ath12k: mark QMI driver event helpers as noinlineJeff Johnson1-9/+25
As described in [1], compiling the ath12k driver using clang with KASAN enabled warns about some functions with excessive stack usage, with the worst case being: drivers/net/wireless/ath/ath12k/qmi.c:3546:13: warning: stack frame size (2456) exceeds limit (1024) in 'ath12k_qmi_driver_event_work' [-Wframe-larger-than] Nathan [2] highlighted work done by Arnd [3] to address similar issues in other portions of the kernel. ath12k_qmi_driver_event_work() itself is a pretty lightweight function, but it dispatches to several other functions which do the real work: ath12k_qmi_driver_event_work() ath12k_qmi_event_server_arrive() ath12k_qmi_host_cap_send() ath12k_qmi_event_mem_request() ath12k_qmi_respond_fw_mem_request() ath12k_qmi_event_load_bdf() ath12k_qmi_request_target_cap() ath12k_qmi_load_bdf_qmi() ath12k_qmi_wlanfw_m3_info_send() Mark all of those underlying functions as 'noinline_for_stack' to prevent them from being inlined in ath12k_qmi_driver_event_work(), thereby eliminating the excessive stack usage.

2024-11-06wifi: ath11k: Suspend hardware before firmware mode off for WCN6750Balaji Pothunoori2-0/+46
During rmmod, the ath11k host driver sends a QMI MODE OFF command to firmware. As part of this command, firmware initiates WLAN de-initialization and accesses certain UMAC registers during this process. Currently, on WCN6750 WLAN hardware, the system is in a sleep state when firmware receives the QMI MODE OFF command. This results in a firmware/hardware reset while accessing the UMAC hardware registers during sleep state. To avoid this, add logic to send WCN6750 hardware specific WMI_PDEV_SUSPEND_AND_DISABLE_INTR command to firmware prior to sending the QMI MODE OFF command. This will cause firmware to cease all activities and put the device in a powered-on state that prevents access to registers which have been powered off.
