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.
