This change is to add trace log support for, * WMI events * WMI commands * ath11k_dbg messages * ath11k_dbg_dump messages * ath11k_log_info messages * ath11k_log_warn messages * ath11k_log_err messages Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.5.0.1-00652-QCAHKSWPL_SILICONZ-1 Signed-off-by: Venkateswara Naralasetty Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/1636439755-30419-1-git-send-email-quic_vnaralas@quicinc.com

ath11k: refactor debugfs code into debugfs.c

2020-09-22T07:41:41Z

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.

ath11k: setup QCA6390 rings for both rxdmas

2020-08-18T09:46:52Z

For QCA6390, only one pdev is created and this pdev manages both lmacs, thus both rxdmas. So host needs to initialize all rxdma related rings for one pdev. Another difference is for QCA6390, host fills rxbuf to firmware and firmware further fills the rxbuf to rxbuf ring for each rxdma.

ath11k: add simple PCI client driver for QCA6390 chipset

2020-08-17T10:07:00Z

QCA6390 is a PCI based 11ax chipset, split AHB into own kernel module ath11k_ahb.ko and add ath11k_pci.ko for PCI devices.

ath11k: Add support for ring backpressure stats

2020-06-15T14:33:12Z

Add support for collecting and dumping the ring backpressure stats via debugfs. Stats are dumped only if events are received for the specific ring. Below command can be used to obtain these stats as part of soc dp stats. cat /sys/kernel/debug/ath11k/ipq8074/soc_dp_stats Sample Output - When No stats available: Backpressure Stats ================== No Ring Backpressure stats received Sample Output - When ring bp stats available for specific ring Backpressure Stats ================== Ring: REO2SW1_RING count: 1 hp: 2 tp: 2 seen before: 4ms Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01213-QCAHKSWPL_SILICONZ-1 Signed-off-by: Sriram R Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/1591768308-32005-3-git-send-email-srirrama@codeaurora.org

ath11k: Add dp tx err stats

2020-06-15T14:33:10Z

Add support for dp tx error stats which logs tx failure reasons due to ring full condition, etc. This stats is added in soc_dp_stats which was earlier used as soc_rx_stats so that all dp related info are logged in same file. Below is an example usage, root@OpenWrt:/# cat /sys/kernel/debug/ath11k/ipq8074/soc_dp_stats SOC RX STATS: err ring pkts: 0 Invalid RBM: 0 SOC TX STATS: Ring Full Failures: ring0: 4 ring1: 3 ring2: 5 Misc Transmit Failures: 2 Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01213-QCAHKSWPL_SILICONZ-1 Signed-off-by: Sriram R Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/1591768308-32005-2-git-send-email-srirrama@codeaurora.org

ath11k: remove conversion to bool in ath11k_debug_fw_stats_process()

2020-04-22T06:42:35Z

The '==' expression itself is bool, no need to convert it to bool again. This fixes the following coccicheck warning: drivers/net/wireless/ath/ath11k/debug.c:198:57-62: WARNING: conversion to bool not needed here drivers/net/wireless/ath/ath11k/debug.c:218:58-63: WARNING: conversion to bool not needed here Signed-off-by: Jason Yan Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20200420123745.4159-1-yanaijie@huawei.com

ath11k: Fix rx_filter flags setting for per peer rx_stats

2020-04-15T08:00:29Z

Rx_filter flags are set with default filter flags during wifi up/down sequence even though the 'ext_rx_stats' debugfs is enabled as 1. So, that we are not getting proper per peer rx_stats. Hence, fixing this by setting the missing rx_filter when ext_rx_stats is already set/enabled.

ath11k: Cleanup in pdev destroy and mac register during crash on recovery

2020-04-15T07:56:59Z

Debugfs pdev entries should be cleaned up during the crash on recovery. If not, mac register will fail for the reason that it is already registered during core reconfigure.
