To mitigate possible RFI interference we introuduced WBRF(Wifi Band RFI mitigation Feature). 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 6.7.0-rc1. With some brief introductions as below: Patch1: Document about WBRF Patch2: Core functionality setup for WBRF feature support Patch3 - 4: Bring WBRF support to wifi subsystem. Patch5 - 9: Bring WBRF support to AMD graphics driver.
