Description Thomas Hellström 2026-01-20 09:29:34 UTC

1. Please describe the problem:

Without CONFIG_DEVICE_PRIVATE, the xe driver won't work properly since starting with
version 6.18 it's required for xe userptr. -> kernel regression.

xe developers is working to automatically select it when needed, meanwhile could you please include it in the fedora kernel configuration?

2. What is the Version-Release number of the kernel:
6.18+

3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :

Previous kernels work.

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:

Run for example the igt test xe-exec-compute-mode on 6.18+

5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:

Unknown

6. Are you running any modules that not shipped with directly Fedora's kernel?:

No.

7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.

Reproducible: Always
