Hi all,
the following commit (taken from 6.6-rt branch) resides in all stable-
rt branches but is not part of mainline 6.12 and above, which makes it
impossible to use i915 in combination with PREEMPT_RT enabled.
Is that by intention? Are there any known issues that makes it
necessary to disable i915 in combination with RT in current releases?
Best regards,
Florian

Revert "drm/i915: Depend on !PREEMPT_RT."
Once the known issues are addressed, it should be safe to enable the
driver.
