UPSTREAM: wifi: ath12k: Add support RX PDEV stats
Add support to request and receive RX pdev firmware stats using HTT stats type 2. This stats type reports PPDU and MPDU counters, firmware ring and buffer statistics, and RX suspend and resume counts. Note: Currently, firmware on mobile-centric chipsets do not maintain these statistics, so a query will not return any information. Sample output: ------------- echo 2 >/sys/kernel/debug/ath12k/pci-0000\:58\:00.0/mac0/htt_stats_type cat /sys/kernel/debug/ath12k/pci-0000\:58\:00.0/mac0/htt_stats HTT_RX_PDEV_FW_STATS_TLV: mac_id = 0 ppdu_recvd = 1522 mpdu_cnt_fcs_ok = 1522 mpdu_cnt_fcs_err = 0 ... fw_ring_mpdu_ind = 1522 fw_ring_mgmt_subtype = 0:0, 1:0, 2:0, 3:0, 4:21, 5:0, 6:0, 7:0, 8:1501, 9:0, 10:0, 11:0, 12:0, 13:0, 14:0, 15:0 fw_ring_ctrl_subtype = 0:0, 1:0, 2:0, 3:0, 4:0, 5:0, 6:0, 7:0, 8:0, 9:0, 10:0, 11:0, 12:0, 13:0, 14:0, 15:0 fw_ring_mcast_data_msdu = 0 fw_pkt_buf_ring_refill_cnt = 1567 fw_pkt_buf_ring_empty_cnt = 1 ... rx_suspend_cnt = 4 rx_suspend_fail_cnt = 0 rx_resume_cnt = 4 rx_resume_fail_cnt = 0 rx_ring_switch_cnt = 0 rx_ring_restore_cnt = 0 Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.5-01651-QCAHKSWPL_SILICONZ-1 Signed-off-by: Aaradhana Sahu <aaradhana.sahu@oss.qualcomm.com> Reviewed-by: Baochen Qiang <baochen.qiang@oss.qualcomm.com> Link: https://patch.msgid.link/20260123071253.2202644-3-aaradhana.sahu@oss.qualcomm.com Signed-off-by: Jeff Johnson <jeff.johnson@oss.qualcomm.com> Signed-off-by: Miaoqing Pan <miaoqing.pan@oss.qualcomm.com>
