Hi Chris, Laurent,
On R-Car Gen2 (Koelsch) and Gen3 (Salvator-X), the new DRM range
manager selftests fail with:
drm_mm: Testing DRM range manger (struct drm_mm), with
random_seed=0x83a9b910 max_iterations=8192 max_prime=128
drm_mm: igt_sanitycheck - ok!
drm_mm: node has wrong color, found 0, expected 1
drm_mm: default insert failed, size 1 step 1
I have no idea what this means.
Gr{oetje,eeting}s,
Geert

The existing code has bugs. We got as far as applying the testcases to
demonstrate the bugs, the actual fix is still queued.

Hm, I thought I merged them all. What's missing?

The actual fix required some coordination between drm-misc and i915
trees, so was delayed. (Only because I wanted to remove repetition of
the bug from i915 first.)
