** Description changed: [ Impact ] * Users cannot use iGPU for video codec (encode/decode) on Intel Arrowlake CPUs on Ubuntu Noble 24.04 * To enable this support, we need to backport this commit https://github.com/intel/media-driver/commit/95cbfce81cafa3c24d9d4601d41a855093bc51fb * This commit has been added in the intel-media-driver 24.2.0, as a consequence, it is already available starting from Plucky. This SRU only affects Ubuntu Noble 24.04 that has an older version (24.1.0). [ Test Plan ] $ sudo apt install -y intel-media-va-driver ffmpeg vainfo VAINFO ---- $ vainfo error: XDG_RUNTIME_DIR is invalid or not set in the environment. error: can't connect to X server! libva info: VA-API version 1.22.0 libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so libva info: Found init function __vaDriverInit_1_22 libva error: /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so init failed libva info: va_openDriver() returns 1 libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so libva info: Found init function __vaDriverInit_1_20 libva error: /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so init failed libva info: va_openDriver() returns -1 vaInitialize failed with error code -1 (unknown libva error),exit We can see that vainfo is unable to list all the supported profiles and endpoints.

Error opening output files: Input/output error [ Where problems could occur ] * Since we backport only a commit that adds some device IDs, the risk to have regressions is small. However, since we enable the platform with media features by adding the needed device IDs, it might enable some code paths and exhibit bugs that are masked without the fix. One way to make sure we do not have big regression is to make sure we can playback a mp4 video (https://test-videos.co.uk/bigbuckbunny/mp4-h265) [ Other Info ]
