PSR currently when enabled results in semi-permanent freezes or noticeable

https://patchwork.freedesktop.org/series/37598/ will fix long freezes due
to frame counter resets.
This series has three more fixes -
Patch 1 eliminates PSR exit for flips and makes us rely on the HW to do it.
Patch 2 fixes cusor move lag by relying on HW to exit PSR.
Patch 3 fixes temporary freeze seen with fbdev.
With both the series applied, PSR on my SKL ThinkPad feels pretty good.
Thank you for your great work on this.
Are there any more PSR fixes in the pipeline? If not I think I should do
a custom Fedora kernel build based on 4.15 + recent fixes and ask all my
testers to retest with that.
I do have some questions before I do this:
1) I believe that only testers with skylake (normal or LP) or newer should
re-test, correct?
2) I know there are 2 series (including this one), can someone provide a link
to the latest patchwork version of those 2 series, or even better a git
branch with 4.15 + those patches? Any patches I'm missing if I pick up these
2 series?
3) I'm thinking 4.15 atm, but I could also do a 4.16-rc1 test kernel instead
if that would be better, would that be better ?
Regards,
Hans
