[v2,00/13] Panel replay selective update support

Message

Hogander, Jouni Jan. 10, 2024, 1:12 p.m. UTC

This patch set is implementing panel replay selective update support
for Intel hardware.

It is also fixing couple of exisiting issues in current panel replay
implementation:

ALPM status is checked even on DP (non eDP)
PSR capability change is checked even when using panel replay
Make psr pause/resume to work for panel replay as well

Panel replay is disabled by default for now. This is done to minimize
possible issues faced by customers as we haven't yet validated the
feature completely.

v2: Make psr pause/resume to work for panel replay as well
