2025-01-12wifi: ath11k: convert timeouts to secs_to_jiffies()Easwar Hariharan
Commit b35108a51cf7 ("jiffies: Define secs_to_jiffies()") introduced secs_to_jiffies(). As the value here is a multiple of 1000, use secs_to_jiffies() instead of msecs_to_jiffies to avoid the multiplication. This is converted using scripts/coccinelle/misc/secs_to_jiffies.cocci with the following Coccinelle rules: @@ constant C; @@ - msecs_to_jiffies(C * 1000) + secs_to_jiffies(C) @@ constant C; @@ - msecs_to_jiffies(C * MSEC_PER_SEC) + secs_to_jiffies(C) Link: https://lkml.kernel.org/r/20241210-converge-secs-to-jiffies-v3-14-ddfefd7e9f2a@linux.microsoft.com Acked-by: Jeff Johnson <quic_jjohnson@quicinc.com> Signed-off-by: Easwar Hariharan <eahariha@linux.microsoft.com> Cc: Alexander Gordeev <agordeev@linux.ibm.com> Cc: Andrew Lunn <andrew+netdev@lunn.ch> Cc: Anna-Maria Behnsen <anna-maria@linutronix.de> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Christian Borntraeger <borntraeger@linux.ibm.com> Cc: Christophe Leroy <christophe.leroy@csgroup.eu> Cc: Daniel Mack <daniel@zonque.org> Cc: David Airlie <airlied@gmail.com> Cc: David S.

2023-10-12wifi: ath11k: Introduce and use ath11k_sta_to_arsta()Jeff Johnson
Currently, the logic to return an ath11k_sta pointer, given a ieee80211_sta pointer, uses typecasting throughout the driver. In general, conversion functions are preferable to typecasting since using a conversion function allows the compiler to validate the types of both the input and output parameters. ath11k already defines a conversion function ath11k_vif_to_arvif() for a similar conversion. So introduce ath11k_sta_to_arsta() for this use case, and convert all of the existing typecasting to use this function. No functional changes, compile tested only.

2023-01-10wifi: ath11k: debugfs: fix to work with multiple PCI devicesKalle Valo
ath11k fails to load if there are multiple ath11k PCI devices with same name: ath11k_pci 0000:01:00.0: Hardware name qcn9074 hw1.0 debugfs: Directory 'ath11k' with parent '/' already present! ath11k_pci 0000:01:00.0: failed to create ath11k debugfs ath11k_pci 0000:01:00.0: failed to create soc core: -17 ath11k_pci 0000:01:00.0: failed to init core: -17 ath11k_pci: probe of 0000:01:00.0 failed with error -17 Fix this by creating a directory for each ath11k device using schema <bus>-<devname>, for example "pci-0000:06:00.0". This directory created under the top-level ath11k directory, for example /sys/kernel/debug/ath11k. The reference to the toplevel ath11k directory is not stored anymore within ath11k, instead it's retrieved using debugfs_lookup(). If the directory does not exist it will be created. After the last directory from the ath11k directory is removed, for example when doing rmmod ath11k, the empty ath11k directory is left in place, it's a minor cosmetic issue anyway. Here's an example hierarchy with one WCN6855: ath11k `-- pci-0000:06:00.0 |-- mac0 | |-- dfs_block_radar_events | |-- dfs_simulate_radar | |-- ext_rx_stats | |-- ext_tx_stats | |-- fw_dbglog_config | |-- fw_stats | | |-- beacon_stats | | |-- pdev_stats | | `-- vdev_stats | |-- htt_stats | |-- htt_stats_reset | |-- htt_stats_type | `-- pktlog_filter |-- simulate_fw_crash `-- soc_dp_stats I didn't have a test setup where I could connect multiple ath11k devices to the same the host, so I have only tested this with one device.

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.

2022-09-02wifi: ath11k: Fix hardware restart failure due to twt debugfs failureManikanta Pubbisetty
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.

2022-09-02wifi: ath11k: Add TWT debugfs support for STA interfaceManikanta Pubbisetty
Currently TWT debugfs files required for manually testing the TWT feature are created only for the AP interfaces; these debugfs hooks are also required for the station interfaces in order to test the TWT feature manually, therefore create these debugfs hooks for station iftype as well. In the case of station interfaces, TWT is entirely handled in the firmware based on input parameters passed to it during association via TWT enable WMI command. In order to manually test this feature, firmware expects to first disable the TWT feature and then send the enable command with sta_cong_timer_ms parameter set to 0. This is true for WCN6750, QCA6390 & WCN6855 hardwares.

2021-12-22codel: remove unnecessary sock.h includeJakub Kicinski
Since sock.h is modified relatively often (60 times in the last 12 months) it seems worthwhile to decrease the incremental build work. CoDel's header includes net/inet_ecn.h which in turn includes net/sock.h. codel.h is itself included by mac80211 which is included by much of the WiFi stack and drivers. Removing the net/inet_ecn.h include from CoDel breaks the dependecy between WiFi and sock.h. Commit d068ca2ae2e6 ("codel: split into multiple files") moved all the code which actually needs ECN helpers out to net/codel_impl.h, the include can be moved there as well. This decreases the incremental build size after touching sock.h from 4999 objects to 4051 objects. Fix unmasked missing includes in WiFi drivers.

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.

2020-10-01ath11k: debugfs: fix crash during rmmodCarl Huang
With QCA6390 when doing rmmod the kernel crashed. The reason was that the destroy functions ath11k_debugfs_pdev_destroy() and ath11k_debugfs_soc_destroy() accidentally had swapped the debugfs directories and ath11k_debugfs_soc_destroy() was removing an already removed directory, which crashed the kernel. The source of confusion is badly named function and variable names. I think the best way to clean this up is actually to merge the corresponding functions, but that's for another patch. Let's first just fix the crash.

2020-10-01ath11k: Correctly check errors for calls to debugfs_create_dir()Alex Dewar
debugfs_create_dir() returns an ERR_PTR in case of error, but never a null pointer. There are a number of places where error-checking code can accordingly be simplified.

2020-09-22ath11k: refactor debugfs code into debugfs.cKalle Valo
If CONFIG_ATH11K_DEBUGFS is disabled there are warnings debug.c: drivers/net/wireless/ath/ath11k/debug.c:36:20: warning: 'htt_bp_lmac_ring' defined but not used [-Wunused-variable] 36 | static const char *htt_bp_lmac_ring[HTT_SW_LMAC_RING_IDX_MAX] = { | ^~~~~~~~~~~~~~~~ drivers/net/wireless/ath/ath11k/debug.c:15:20: warning: 'htt_bp_umac_ring' defined but not used [-Wunused-variable] 15 | static const char *htt_bp_umac_ring[HTT_SW_UMAC_RING_IDX_MAX] = { | ^~~~~~~~~~~~~~~~ Fix this by refactoring debugfs code to debugfs.c. This also reduces the number of ifdefs in debug.c and makes it easier to maintain the code. No functional changes. Compile tested only.
