> Please test if that patch changes anything.
Looks like the driver is not functional after applying that patch. As
soon as the display manager is supposed to start I get a black screen
with just a (working) mouse pointer. VT switching doesn't work after
that point.
I got the following warning when compiling with that patch applied:
drivers/gpu/drm/nouveau/nouveau_fence.c: In function ‘nouveau_fence_sync’:
drivers/gpu/drm/nouveau/nouveau_fence.c:362:24: warning: comparison between pointer and integer
362 | for (i = 0; (i < fobj ? fobj->shared_count : 0) && !ret; ++i) {
| ^
Below are the relevant portions from dmesg after attempting to run
with the patch applied.
Cheers,
