We have AMD system where Ubuntu is host as DOM and AGL(demo ivi version) as domU VM.
Issue description
When we put VM on sleep and then resume, resume(display light up) takes randomly takes huge time, from 10 sec to 30 sec. this happens only when when display has static frames, if we some application that makes display flips(for example glmark2, top command) then display lights up happens faster after resume.
command used for sleep and resume from dom0 Ubuntu
sudo xl trigger <AGL-ID> sleep
sudo xl trigger <AGL-ID> s3resume

Just fyi, I'm afraid that I can't really try out this now, we're not actually using Xen so I need to set-up xen with this in order to make it work. It will probably take some time, or if I get some time it won't happen to soon.
