wifi: ath12k: Support Pdev OBSS Stats
JIRA: https://issues.redhat.com/browse/RHEL-79791 commit 15d9142 Author: Dinesh Karthikeyan <[email protected]> Date: Sat Oct 5 16:12:06 2024 +0530 wifi: ath12k: Support Pdev OBSS Stats Add support to request pdev OBSS stats from firmware through stats type 23. These stats give information about PPDUs transmitted or tried to be transmitted in Spatial Reuse Groups(SRG), Parameterized Spatial Reuse(PSR) and non-PSR groups. Sample output: ------------- echo 23 > /sys/kernel/debug/ath12k/pci-0000\:06\:00.0/mac0/htt_stats_type cat /sys/kernel/debug/ath12k/pci-0000\:06\:00.0/mac0/htt_stats HTT_PDEV_OBSS_PD_STATS_TLV: num_spatial_reuse_tx = 0 num_spatial_reuse_opportunities = 0 num_non_srg_opportunities = 0 num_non_srg_ppdu_tried = 0 ..... HTT_PDEV_OBSS_PD_PER_AC_STATS: Access Category 0 (best effort) num_non_srg_ppdu_tried = 0 num_non_srg_ppdu_success = 0 num_srg_ppdu_tried = 0 num_srg_ppdu_success = 0 Access Category 1 (background) num_non_srg_ppdu_tried = 0 num_non_srg_ppdu_success = 0 num_srg_ppdu_tried = 0 num_srg_ppdu_success = 0 .....
