Hi Greg and Kevin,
Sorry for inconvenience, but this one should be reverted by another
backport patch:
"drm/amd/display: Solve mst monitors blank out problem after resume"
What commit id in Linus's tree is that?
From what I can tell it's: e33697141bac18 ("drm/amd/display: Solve mst monitors blank out problem after resume")
You've send out a message that it failed to apply to a few of the stable trees:
- 6.10: https://lore.kernel.org/stable/2024081212-vitally-baked-7f93@gregkh/
- 6.6 : https://lore.kernel.org/stable/2024081213-roast-humorless-fd20@gregkh/
- 6.1 : https://lore.kernel.org/stable/2024081213-sweep-hungry-2d10@gregkh/
To apply it on top of 6.10.5-rc1 these two patches need to be applied first: f63f86b5affcc2 ("drm/amd/display: Separate setting and programming of cursor") 1ff6631baeb1f5 ("drm/amd/display: Prevent IPX From Link Detect and Set Mode")
I don't know if that solves the problem I initially described as I'm currently on a different setup. What I can say is that it applying those three patches on
Applying the three patches I listed above, fixes the problem for my setup. My external 4k monitors now get a signal both on boot and when resuming from sleep.
Thanks for the report, I'll drop this commit for now from the trees and then add back all of them for the next round of -rc releases for people to test.
