s2idle not working

[shahul hameed]

Hi All,

I did below exoeriments:

-> S2idle is working in software rendering mode(disable AMDGPU driver).

-> For experiment purpose i commented suspend/resume calls of amdgpu
driver, in this case S2idle worked.
With above experiments it is clear that my platform supports s2idel.
Some issue in AMDGPU suspend/resume sequence for s2idle.
So can you please help me.

Thanks & Regards,
Sk shahul.
