By the way, not related to this issue:
I cherry-picked
https://patchwork.kernel.org/project/dri-devel/patch/[email protected]/
and got a blank FB console on OPI3.
Can you check it please?

This particular patch and the one I've sent today [1] aims to fix the
ZPOS issue you're talking about.
Second patch [1] fixes https://github.com/rsglobal/kmsxx/pull/3 test
and unlike this patch it does not cause additional regressions (as far
as I can test).

Despite the fact that I am the original author of the patches I'm not
even in CC, so I can respond to this thread.
Is there any other way to respond to the message where you're not in CC?
