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 6.4-rc3. With some brief introductions as below: Patch1: Core ACPI interfaces needed to support WBRF feature. Patch2 - 3: Enable WBRF support for wifi subsystem. Patch4 - 8: Enable WBRF support for AMD graphics driver. Evan Quan (7): 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 Mario Limonciello (1): drivers/acpi: Add support for Wifi band RF mitigations drivers/acpi/Kconfig | 7 + drivers/acpi/Makefile | 2 + drivers/acpi/acpi_wbrf.c | 215 ++++++++++++++++++ drivers/gpu/drm/amd/amdgpu/amdgpu.h | 26 +++ drivers/gpu/drm/amd/amdgpu/amdgpu_acpi.c | 63 +++++ drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 19 ++ drivers/gpu/drm/amd/pm/swsmu/amdgpu_smu.c | 204 +++++++++++++++++ drivers/gpu/drm/amd/pm/swsmu/inc/amdgpu_smu.h | 30 +++ .../inc/pmfw_if/smu13_driver_if_v13_0_0.h | 14 +- .../inc/pmfw_if/smu13_driver_if_v13_0_7.h | 14 +- .../pm/swsmu/inc/pmfw_if/smu_v13_0_0_ppsmc.h | 3 +- .../pm/swsmu/inc/pmfw_if/smu_v13_0_7_ppsmc.h | 3 +- drivers/gpu/drm/amd/pm/swsmu/inc/smu_types.h | 3 +- drivers/gpu/drm/amd/pm/swsmu/inc/smu_v13_0.h | 3 + .../gpu/drm/amd/pm/swsmu/smu13/smu_v13_0.c | 9 + .../drm/amd/pm/swsmu/smu13/smu_v13_0_0_ppt.c | 60 +++++ .../drm/amd/pm/swsmu/smu13/smu_v13_0_7_ppt.c | 59 +++++ drivers/gpu/drm/amd/pm/swsmu/smu_internal.h | 3 + include/linux/ieee80211.h | 1 + include/linux/wbrf.h | 55 +++++ include/net/cfg80211.h | 8 + net/mac80211/Makefile | 2 + net/mac80211/chan.c | 11 + net/mac80211/ieee80211_i.h | 19 ++ net/mac80211/main.c | 2 + net/mac80211/wbrf.c | 111 +++++++++ net/wireless/chan.c | 3 +- 27 files changed, 943 insertions(+), 6 deletions(-) create mode 100644 drivers/acpi/acpi_wbrf.c create mode 100644 include/linux/wbrf.h create mode 100644 net/mac80211/wbrf.c -- 2.34.1
