[AMD Official Use Only - General]
Hi Marius and all,
We are facing issue in display lightup, where it takes more than 20s to light up diplay after resume. I am describing issue in detail in below.
Setup detail
--------------------------------------------------
Platform - amd ryzen apu
OS details - Xen, Ubuntu as dom0 and agl domU.
Issue description
------------------------------------------------------------------
When we are suspending agl domU and then resuming back display lightup takes very long randomly from 3sec to 30 sec around, however agl vm becomes accessible just after 1 sec, we are able to access via ssh and xl console. not getting any
clue form dmesg or journalctl.
Extra info - if we run some GPU load applications such as Glmark2 and then do s3 and resume, we don't see this issue and display lightup comes back in a second.
Command used for s3 and resume
--------------------------
xl trigger <agl domid> sleep
xl trigger <agl domid> s3resume
Please provide inputs to assess why extra time is taken gui resume.
Best Regards
Rahul
