Subject: [PATCH V6 0/9] Enable Wifi RFI interference mitigation feature support
Date: Mon, 10 Jul 2023 16:36:32 +0800 [thread overview]
Message-ID: <20230710083641.2132264-1-evan.quan@amd.com> (raw)
Due to electrical and mechanical constraints in certain platform designs there may
be likely interference of relatively high-powered harmonics of the (G-)DDR memory
clocks with local radio module frequency bands used by Wifi 6/6e/7. To mitigate
possible RFI interference producers can advertise the frequencies in use and
consumers can use this information to avoid using these frequencies for
sensitive features.
The whole patch set is based on Linux 6.4. With some brief introductions as below:
Patch1 - 2: Core functionality setup for WBRF feature support
Patch3 - 4: Bring WBRF support to wifi subsystem.
Patch5 - 9: Bring WBRF support to AMD graphics driver.
Evan Quan (9):
drivers core: Add support for Wifi band RF mitigations
driver core: add ACPI based WBRF mechanism introduced by AMD
cfg80211: expose nl80211_chan_width_to_mhz for wide sharing
wifi: mac80211: Add support for ACPI WBRF
drm/amd/pm: update driver_if and ppsmc headers for coming wbrf feature
drm/amd/pm: setup the framework to support Wifi RFI mitigation feature
drm/amd/pm: add flood detection for wbrf events
drm/amd/pm: enable Wifi RFI mitigation feature support for SMU13.0.0
drm/amd/pm: enable Wifi RFI mitigation feature support for SMU13.0.7
