Hi Aurabindo, thanks for your response!
I've tried kernel 6.5-rc1, and it seems the issue is present, due to the
patch being merged on Linus tree [as 1598fc576420 ("drm/amd/display:
Program OTG vtotal min/max selectors unconditionally for DCN1+")].
Then, I tried both your attached patches on top of that, and
unfortunately, the behavior is the same: Steam Deck doesn't boot with
graphics, and we can see the single error "amdgpu 0000:04:00.0: [drm]
*ERROR* [CRTC:67:crtc-0] flip_done timed out" on dmesg.
Do you / Alex think we could get this revert for 6.5-rc2, so at least we
could boot mainline there while the issue is handled? It would be an
intermediate fix. You mentioned it breaks some asics, but did they work
until now, without your patch?
Thanks,
Guilherme
