wifi: ath12k: Support pdev CCA Stats
JIRA: https://issues.redhat.com/browse/RHEL-79791 commit 3f5ecfc Author: Dinesh Karthikeyan <[email protected]> Date: Sat Oct 5 15:48:16 2024 +0530 wifi: ath12k: Support pdev CCA Stats Add support to request CCA stats for physical devices from firmware through HTT stats type 19. These stats give information about channel number, number of records, counters' bitmap, collection interval and different CCA counters. Sample output: ------------- echo 19 > /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_CCA_STATS_HIST_TLV (1s): chan_num = 5955 num_records = 10 valid_cca_counters_bitmap = 0xff collection_interval = 1000 HTT_PDEV_STATS_CCA_COUNTERS_TLV:(in usec) tx_frame_usec = 0 rx_frame_usec = 0 rx_clear_usec = 999955 my_rx_frame_usec = 0 usec_cnt = 999955 med_rx_idle_usec = 0 med_tx_idle_global_usec = 0 cca_obss_usec = 999955 .....
