The pdev id is set to 0 for single pdev configured hardware, the real pdev id is not 0 in firmware, for example, its pdev id is 1 for 5G/6G phy and 2 for 2G band phy. For HTT_H2T_MSG_TYPE_EXT_STATS_CFG message, firmware parse the pdev_mask to its pdev id, ath11k set it to 0 for single pdev, it is not correct, need set it with the real pdev id of firmware. Save the real pdev id report by firmware and set it correctly. Below commands run success with this patch: cat /sys/kernel/debug/ieee80211/phy0/ath11k/htt_stats cat /sys/kernel/debug/ieee80211/phy0/netdev\:wls1/stations/00\:03\:7f\:75\:59\:85/htt_peer_stats Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1 Signed-off-by: Wen Gong <quic_wgong@quicinc.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20211118095700.8149-1-quic_wgong@quicinc.com
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
