<pre>Thanks for the information Chris,
I did some experiemnts and found that intel_eDP_drrs_invalidate has to be added
to the intel_frontbuffer_flip_prepare.
With this on ubuntu Desktop environment eDP Idleness DRRS is working. But to
test the all corner case I am developing a IGT. In IGT environment DRRS not
updated in few situations. Have to divein further for more info.
For now I have submitted a patch to add the drrs_invalidate to the
frontbuffer_flip_prepare.</pre>
