wifi: ath11k: move some firmware stats related functions outside of debugfs

2025-06-19T13:40:53Z

[ Upstream commit 72610ed7d79da17ee09102534d6c696a4ea8a08e ] Commit b488c766442f ("ath11k: report rssi of each chain to mac80211 for QCA6390/WCN6855") and commit c3b39553fc77 ("ath11k: add signal report to mac80211 for QCA6390 and WCN6855") call debugfs functions in mac ops. Those functions are no-ops if CONFIG_ATH11K_DEBUGFS is not enabled, thus cause wrong status reported. Move them to mac.c. Besides, since WMI_REQUEST_RSSI_PER_CHAIN_STAT and WMI_REQUEST_VDEV_STAT stats could also be requested via mac ops, process them directly in ath11k_update_stats_event().

wifi: ath11k: rely on mac80211 debugfs handling for vif

2024-01-18T09:58:42Z

mac80211 started to delete debugfs entries in certain cases, causing a ath11k to crash when it tried to delete the entries later. Fix this by relying on mac80211 to delete the entries when appropriate and adding them from the vif_add_debugfs handler.

wifi: ath11k: move firmware stats out of debugfs

2022-09-22T07:28:20Z

Currently, firmware stats, comprising pdev, vdev and beacon stats are part of debugfs. In firmware pdev stats, firmware reports the final Tx power used to transmit each packet. If driver wants to know the final Tx power being used at firmware level, it can leverage from firmware pdev stats. Move firmware stats out of debugfs context in order to leverage the final Tx power reported in it even when debugfs is disabled.

wifi: ath11k: Fix hardware restart failure due to twt debugfs failure

2022-09-02T12:27:11Z

Currently, creation of debugfs entries for TWT is failing during hardware restart because of the residual TWT files which were created during add_interface(). Since, struct arvif{} is memset to zero upon add_interface() invocation, when the hardware restart is triggered, arvif is memset to 0 and TWT files are attempted to create again which will fail because of the residual TWT files already in place, this leads to hardware restart failure. Also, it is not a good idea to return error from add_interface() because of debugfs file creation failures. Moreover, debugfs framework can very well handle the errors in it's create file & remove file APIs and the errors returned by these APIs are not checked in most usecases. Fix the HW restart failure by ignoring the errors returned from the debugfs APIs.

ath11k: add dbring debug support

2022-02-24T09:02:48Z

Target copies spectral report and CFR report through dbring to host for further processing. This mechanism involves ring and buffer management in the Host, FW, and uCode, where improper tail pointer update issues are seen. This dbring debug support help to debug such issues by tracking head and tail pointer movement along with the timestamp at which each buffer is received and replenished. Provide a debugfs interface to enalbe/disable dbring debug support and dump the dbring debug entries. Also introduced a new hardware param to add dbring debugfs support for few hardwares which are using dbings. Usage: echo > /sys/kernel/debug/ath11k/ipq8074_2/ mac0/enable_dbr_debug dbr_id: 0 for spectral and 1 for CFR val: 0 - disable, 1 - enable.

ath11k: Add debugfs interface to configure firmware debug log level

2022-02-01T10:56:14Z

Add debugfs interface "fw_dbglog_config" to configure firmware log level. Configuration is done via WMI command WMI_DBGLOG_CFG_CMDID. Command to configure, echo " " > /sys/kernel/debug/ath11k//macX/fw_dbglog_config where dbglog_param can be, 1) WMI_DEBUG_LOG_PARAM_LOG_LEVEL - configure log level for a given module here, = <0xaaaa00bb>, 'aaaa' - module id and 'bb' - loglevel 2) WMI_DEBUG_LOG_PARAM_VDEV_ENABLE - enable debug log for a given vdev here, = vdev_id 3) WMI_DEBUG_LOG_PARAM_VDEV_DISABLE - disable debug log for a given vdev except ERROR logs here, = vdev_id 4) WMI_DEBUG_LOG_PARAM_VDEV_ENABLE_BITMAP - set vdev enable bitmap here, = vdev_enable_bitmap 5) WMI_DEBUG_LOG_PARAM_MOD_ENABLE_BITMAP - set a given log level to all the modules specified in the module bitmap. Command to configure for this log param, $ echo "5 " > /sys/kernel/debug/ath11k//macX/fw_dbglog_config here, = <0xaaaaaaaa000000bb>, 'aaaaaaaa' - module bitmap and 'bb' - loglevel = index of module bitmap. Max module id is 512. So, module_id_index is 0-15. = to indicate if more configuration to follow. 6) WMI_DEBUG_LOG_PARAM_WOW_MOD_ENABLE_BITMAP - Wow mode specific logging enable.
