From f40a307eb92c45a4acf813efcda90b17d50d25c3 Mon Sep 17 00:00:00 2001 From: Surabhi Vishnoi Date: Tue, 26 Feb 2019 15:23:16 +0530 Subject: ath10k: Fill rx duration for each peer in fw_stats for WCN3990 Currently, rx_duration for each peer is not getting populated in fw_stats debugfs entry for WCN3990. WCN3990 firmware sends rx duration for each peer as part of peer_extd_stats in WMI_UPDATE_STATS_EVENT. To enable peer_extd_stats, firmware expects host to send fw_stats_req_mask with flag WMI_TLV_PEER_STATS_EXTD set in WMI_REQUEST_STATS_CMD. Send fw_stats_req_mask with flag WMI_TLV_PEER_STATS_EXTD set in WMI_REQUEST_STATS_CMD and parse the peer_extd_stats in WMI_UPDATE_STATS_EVENT to populate the rx_duration of each peer in fw_stats debugfs entry. Currently the driver handles 32-bit rx_duration, but the rx_duration for WCN3990 can be upto 63 bit. The firmware sends rx_duration split into two 32-bit fields, with the upper 32-bits being valid only if its MSB is set. This change handles the 63-bit rx_duration obtained from WCN3990 and maintain the backward compatibility.
