i915 driver Panel Self Refresh (PSR) status update

Hi All,

First of Thank you to everyone who has been sending me PSR test results, I've received well over a 100 reports!

Quite a few testers have reported various issues when enabling PSR, 3 often reported issues are:

  • flickering

  • black screen

  • cursor / input lag

The Intel graphics team has been working on a number of fixes which make PSR work better in various cases. Note we don't expect this to fix it everywhere, but it should get better and work on more devices in the near future.

This is good news, but the bad news is that this means that all the tests people have so very kindly done for me will need to be redone once the new improved PSR code is ready for testing. I will do a new blogpost (and email people who have send me test-reports), when the new
PSR code is ready for people to (re-)test (sorry).

Regards,

Hans
