#17660 new bug

VEGA 56 black screen

Reported by: andreas_dr Owned by: kallisti5
Priority: normal Milestone: Unscheduled
Component: Drivers/Graphics/radeon_hd Version: R1/Development
Keywords: Cc:
Blocked By: Blocking:
Platform: All



i think its obvious that VEGA56 modesetting in accelerant/via kernel driver, both named "radeon_hd" is not working.

I try to gather some information, maybe to help, to fix those issues.

Symthoms are that screen gets black and nothing can be done anymore, although changing Num lock and Caps lock is working.

Please see attached my VEGA56 BIOS and radeon_hd traces.

What revision is this?

comment:3 by andreas_dr, 11 months ago

Its a custom build to extract the BIOS(it was deleted after next boot without accelerant) and traces. I should be able to give you the commit hash if thats sufficient. But I build yesterday freshly from sources. So 22-03-16.

Duplicate #17516 ?

Yes but in my ticket the trace is complete from RADEON_HD and you see that BIOS does not get parsed correctly, which leads to all other problems. Also I have attached the BIOS so that the dev can adapt parser to it, at least this was one idea from me.

But yes, seems to be a duplicate.
