    DRI isn’t an X thing, it’s a kernel thing. DRI is how the kernel provides an interface for userspace applications to talk to a GPU; all modern video drivers are written for DRI. Wayland was created with the assumption DRI exists, a Wayland compositor *cannot* live without DRI.

    X existed long before modern GPUs did - originally, video drivers (for 2D “graphics accelerators”, because again, 3D GPUs did not exist yet) were written for the X server itself. If that sounds like it would become hacky and problematic very quickly, especially once 3D GPUs came onto the scene in the mid 90s, well, that’s because it did - hence the need for DRI to be invented!

    What these merge requests are about, is removing old cruft related to the ancient DRI version 1 which no one uses anymore. DRI 3, released in 2013, is the current version.

    It's mentioned in the pull request linked in the article: https://gitlab.freedesktop.org/mesa/...requests/28138
    it will likely be fixed first in xorg
    Thanks for clarification.

    Nothing. Removing these ancient headers doesn't affect anyone using modern hardware.

    Once whistleblowers start dying, maybe.

    Thanks.
    Sure. It’s actually embedded two stories down from this one on the Phoronix homesite. Look for the first story under the date stamp March 12 entitled “ OBS RELEASED WITH AV1 SUPPORT “. Click that article and look in the comments for the poster “ shmerl “. He’s the first to leave a comment. Click on the link he (she) embedded in their reply in the bug with AMD VCN 4 . That will take you to Freedesktop.org and an issue page for Mesa. It concerns VAAPI and encoding AV1 video at a prescribed size but AMD cards with VCN 4 can’t get it right because it’s broken at the hardware level so it introduces a black pad top and bottom. Read the whole thread and you will eventually get to a poster named “ Ruijing Dong “. He’s the one who states AMD VCN 4 is broken in hardware and that he confirmed with “our HW/FW” team that VCN 4 is broken and won’t be fixed until the release of VCN 5 hardware.
