Subject: [PATCH] wifi: ath11k: change to move WMI_VDEV_PARAM_SET_HEMU_MODE before WMI_PEER_ASSOC_CMDID
Date: Wed, 31 Jan 2024 10:18:32 +0800 [thread overview]
Message-ID: <20240131021832.17298-1-quic_bqiang@quicinc.com> (raw)
From: Wen Gong <quic_wgong@quicinc.com>
Currently when connecting to an AP with 11AX-HE phy mode, host sends
WMI_VDEV_PARAM_SET_HEMU_MODE parameter to firmware after
WMI_PEER_ASSOC_CMDID command. This results in TXBF not working, because
firmware calculates TXBF values while handling WMI_PEER_ASSOC_CMDID,
however at that time WMI_VDEV_PARAM_SET_HEMU_MODE has not been sent yet.
See below log:
AP sends "VHT/HE/EHT NDP Announcement" to station, and station sends
"Action no Ack" of category code HE to AP, the "Nc Index" and
"Codebook Information" are wrong:
Issued action:
IEEE 802.11 Action No Ack, Flags: ........
IEEE 802.11 wireless LAN
Fixed parameters
Category code: HE (30)
HE Action: HE Compressed Beamforming And CQI (0)
Total length: 152
HE MIMO Control: 0x0004008018
.... .... .... .... .... .... .... .... .... .000 = Nc Index: 1 Column (0)
.... .... .... .... .... .... .... ..0. .... .... = Codebook Information: 0
Change to send WMI_VDEV_PARAM_SET_HEMU_MODE before WMI_PEER_ASSOC_CMDID,
then firmware will calculate the TXBF values with valid parameters
instead of empty values. TXBF works well and throughput performance is
improved from 80 Mbps to 130 Mbps with this patch.
Good action after this patch:
IEEE 802.11 Action No Ack, Flags: ........
IEEE 802.11 wireless LAN
Fixed parameters
Category code: HE (30)
HE Action: HE Compressed Beamforming And CQI (0)
Total length: 409
HE MIMO Control: 0x0004008219
.... .... .... .... .... .... .... .... .... .001 = Nc Index: 2 Columns (1)
.... .... .... .... .... .... .... ..1. .... .... = Codebook Information: 1
This change applies to all chipsets.
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.23
