Public bug reported: /dev/dri/ render devices are tagged for uaccess (logged in users are granted permissions). This allows GPUs to work directly for actively logged in users:
https://github.com/systemd/systemd/commit/30a1a29d4e72a6097657b2be9e0b17cff92fba44 /dev/accel/* and /dev/kfd however are not tagged like this and they should be. This is important for devices like NPUs and for AMD GPUS that run compute (such as ROCm). This involves backporting the following commits: https://github.com/systemd/systemd/commit/e30c044c23c1dc7ef44ccb3892d942dc256d1b02 https://github.com/systemd/systemd/pull/40888 After testing there might be a few other related ones to backport in related code paths (for example https://github.com/systemd/systemd/commit/d0ad8f11759597969df0c10318b6b7d53415d1f7). ** Affects: systemd (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2143010 Title: FFe: Tag accel and kfd devices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/2143010/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
