(In reply to Olivier Certner from comment #47)

The above-mentioned pull request was merged, as well as companion ones
(backports to 5.10, 5.15, 6.1 and 6.6).

So really, you should not observe any more slowdowns (at least due to
physically-contiguous allocations) on any versions built from recent stable/14
and stable/15, whichever DRM kmod version you are using.  Please make sure to
recompile both your kernels and the your drm-kmod module.

Release-wise, the fixes will be in 15.0, and 14.4 (first semester 2026).  We
may want to issue ENs for 14 though.

Due to the nature of the problem and fixes, we might still experience
regressions as drm-kmod but also our LinuxKPI are updated (we had such a
regression for 14.3, annihilating the benefit of my initial fixes over 14.2 at
the beginning of the year), re-introducing physically-contiguous allocations
that are not really needed in hot paths.

So please test and report as things evolve.

Thanks and regards.
