AMD has taken a major step toward enabling native open-source HDMI 2.1 support on Linux by submitting new patches for its AMDGPU driver. <\/p>\n

AMD Moves Closer to Open-Source HDMI 2.1 Support on Linux With New AMDGPU FRL Patches<\/h2>\n

It appears that the HDMI 2.1 support is finally arriving to Linux as AMD has submitted the new Fixed Rate Link (FRL) patches for its AMDGPU driver. This has been one of the longest-standing limitations that affected Radeon GPUs on the platform. There have been years of restrictions tied to the HDMI Forum (Org behind the HDMI standard) policies that prevented upstream implementation of HDMI 2.1. <\/p>\n

As spotted by Phoronix, the new patches introduce HDMI 2.1 FRL support to the AMDGPU display driver, which will serve as a key transport upgrade required for modern displays that boast high resolution and refresh rates. According to the patch notes, the implementation has already passed some HDMI compliance tests, and full validation is underway. Remember that this submission doesn’t include the complete HDMI 2.1 feature stack, as capabilities such as DSC or Display Stream Compression are still being prepared. <\/p>\n

“This patch series adds HDMI FRL support to the amdgpu display driver. DSC is still being tested and will be sent out later.<\/strong><\/p>\n

This work passed a representative subset of HDMI compliance and a full compliance run on this branch is in the works. We don’t expect the full run to show any failures since it passes in other environments.<\/strong><\/p>\n

Thanks to Siqueira who prepared this work a couple years back and unfortunately didn’t manage to send them while he was still working at AMD.<\/strong><\/p>\n

Thanks to Jerry who has been making this code solid on Linux and running the compliance tests.<\/strong><\/p>\n

The first patch in the series isn’t related to HDMI 2.1 but included here because it moved the code around some key bits of the HDMI 2.1 stuff around too much. It will land with the next DC Patch series.”<\/strong><\/p>\n
