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 drivers/acpi/Makefile | 2 + drivers/acpi/amd_wbrf.c | 236 +++++++++++++++++ drivers/base/Kconfig | 37 +++ drivers/base/Makefile | 1 + drivers/base/wbrf.c | 250 ++++++++++++++++++ drivers/gpu/drm/amd/amdgpu/amdgpu.h | 1 + drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 19 ++ drivers/gpu/drm/amd/pm/swsmu/amdgpu_smu.c | 214 +++++++++++++++ drivers/gpu/drm/amd/pm/swsmu/inc/amdgpu_smu.h | 33 +++ .../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/acpi_amd_wbrf.h | 38 +++ include/linux/ieee80211.h | 1 + include/linux/wbrf.h | 67 +++++ include/net/cfg80211.h | 8 + net/mac80211/Makefile | 2 + net/mac80211/chan.c | 9 + net/mac80211/ieee80211_i.h | 19 ++ net/mac80211/main.c | 2 + net/mac80211/wbrf.c | 103 ++++++++ net/wireless/chan.c | 3 +- 29 files changed, 1210 insertions(+), 6 deletions(-) create mode 100644 drivers/acpi/amd_wbrf.c create mode 100644 drivers/base/wbrf.c create mode 100644 include/linux/acpi_amd_wbrf.h create mode 100644 include/linux/wbrf.h create mode 100644 net/mac80211/wbrf.c -- 2.34.1
