> Subject: [PATCH V7 0/9] Enable Wifi RFI interference mitigation feature
> support
>
> 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
