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 - 4: Enable WBRF support for some Mediatek and Qualcomm wifi drivers. Patch5 - 9: Enable WBRF support for AMD graphics driver. Anson Tsao (1): wifi: ath11k: Add support to the Qualcomm ath11k for ACPI WBRF Evan Quan (6): wifi: ath12k: Add support to the Qualcomm ath12k 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 (2): drivers/acpi: Add support for Wifi band RF mitigations mt76: Add support to the Mediatek MT7921 for ACPI WBRF drivers/acpi/Kconfig | 7 + drivers/acpi/Makefile | 2 + drivers/acpi/acpi_wbrf.c | 343 ++++++++++++++++++ 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 | 31 ++ .../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 | 62 ++++ .../drm/amd/pm/swsmu/smu13/smu_v13_0_7_ppt.c | 61 ++++ drivers/gpu/drm/amd/pm/swsmu/smu_internal.h | 3 + drivers/net/wireless/ath/Makefile | 1 + drivers/net/wireless/ath/acpi_wbrf.c | 45 +++ drivers/net/wireless/ath/ath.h | 15 + drivers/net/wireless/ath/ath11k/core.c | 23 ++ drivers/net/wireless/ath/ath11k/core.h | 14 + drivers/net/wireless/ath/ath11k/mac.c | 4 + drivers/net/wireless/ath/ath11k/pci.c | 3 + drivers/net/wireless/ath/ath12k/core.c | 21 ++ drivers/net/wireless/ath/ath12k/core.h | 14 + drivers/net/wireless/ath/ath12k/mac.c | 4 + drivers/net/wireless/ath/ath12k/pci.c | 3 + drivers/net/wireless/mediatek/mt76/Makefile | 1 + .../net/wireless/mediatek/mt76/acpi_wbrf.c | 36 ++ drivers/net/wireless/mediatek/mt76/mt76.h | 19 + .../net/wireless/mediatek/mt76/mt7921/init.c | 2 + .../net/wireless/mediatek/mt76/mt7921/main.c | 3 + include/linux/wbrf.h | 70 ++++ 35 files changed, 1143 insertions(+), 5 deletions(-) create mode 100644 drivers/acpi/acpi_wbrf.c create mode 100644 drivers/net/wireless/ath/acpi_wbrf.c create mode 100644 drivers/net/wireless/mediatek/mt76/acpi_wbrf.c create mode 100644 include/linux/wbrf.h -- 2.34.1
