Initial AMDGPU HDMI 2.1 FRL Support Successfully Merged For Linux 7.2

The initial AMDGPU HDMI 2.1 Fixed Rate Link (FRL) support has been successfully merged into Linux 7.2, though it is disabled by default and the full HDMI 2.1 implementation is not yet complete. The merge also includes new display power management features, continued enablement for next-gen graphics IP, and expanded NPU driver support for AMD and Intel hardware.

The Linux 7.2 DRM merge is headlined by the long-awaited HDMI 2.1 Fixed Rate Link FRL support for the AMDGPU open-source driver as part of the larger effort of finally proceeding with a full HDMI 2.1 implementation for this AMD Radeon Linux driver.The AMDGPU HDMI 2.1 FRL support https://www.phoronix.com/news/HDMI-FRL-2.1-Submitted-DRM was successfully merged into Linux 7.2. The feature is initially disabled by default https://www.phoronix.com/news/AMDGPU-FRL-Disabled-By-Default and the complete HDMI 2.1 implementation for AMDGPU isn't ready for Linux 7.2, but at least the initial FRL capabilities are wired up for allowing higher resolutions and higher refresh rates when using modern HDMI displays.In addition to AMDGPU HDMI 2.1 FRL, there is also the introduction of the AMDGPU DC Power Module https://www.phoronix.com/news/Linux-7.2-AMDGPU-Power-Mod for better matching the display power management behavior of Radeon Software on Windows. Hopefully this will lead to a better experience and less bugs.Also on the AMD side is continued enablement for next-gen graphics IP https://www.phoronix.com/news/More-AMDGPU-For-Linux-7.2 . Though with their versioning practices and block-by-block enablement, it's difficult to ascertain the precise product support at this time.AMDGPU also has better handling for non-4K kernel page sizes https://www.phoronix.com/news/Linux-7.2-AMDGPU-Non-4K such as on ARM and POWER.With the AMDXDNA accelerator driver for Ryzen AI NPUs is expandable heap support https://www.phoronix.com/news/AMDXDNA-Expandable-Heap and enabling next-gen AIE4 NPU hardware https://www.phoronix.com/news/Linux-72-drm-misc-next-More-AIE . There is also new power management features https://www.phoronix.com/news/AMD-Intel-NPU-Drivers-Power-7.2 for both the AMDXDNA and Intel IVPU NPU drivers.Over on the Intel kernel graphics driver side there is now DRM background color property support https://www.phoronix.com/news/Intel-Graphics-Background-Color , preparing for multiple Crescent Island SKUs https://www.phoronix.com/news/Intel-Xe-Multi-Crescent-Island , Panel Replay Tunneling support https://www.phoronix.com/news/Linux-7.2-Panel-Replay-Tunnel , SR-IOV enabling for Nova Lake Xe3P graphics https://www.phoronix.com/news/Intel-Nova-Lake-Graphics-SR-IOV , and even a fix for old Sandy Bridge era graphics https://www.phoronix.com/news/Linux-7.2-Sandy-Bridge-iGFX-Fix . Intel Crescent Island for that upcoming enterprise AI accelerator continues to be a big focus for the Intel Linux software engineers.There is also continued work on the NVIDIA Nova Rust driver https://www.phoronix.com/news/Linux-7.2-DRM-Rust and working toward Hopper and Blackwell GPU support.
