Subject: [PATCH] drm/i915: use TRANS_PUSH frame changes for PSR/Panel Replay
Subject: [PATCH] drm/i915: use TRANS_PUSH frame changes for Panel Replay
Panel Replay Selective Update requires a software-triggered Frame Change
event via TRANS_PUSH to send dirty regions to the panel. Cursor updates
can skip the normal VRR push path, so the panel may not receive cursor
position changes under Panel Replay SU.
Backport the upstream TRANS_PUSH frame-change flow for display 20+:
program the PSR/PR frame-change bit when PSR is enabled, skip the old
CURSURFLIVE frame-change path on platforms using TRANS_PUSH, and send a
push for legacy cursor updates when PSR/Panel Replay uses TRANS_PUSH.
Backport the upstream TRANS_PUSH frame-change flow for display 20+,
but keep it limited to Panel Replay for linux-ptl. Plain PSR2 must keep
using the old CURSURFLIVE frame-change path so systems still boot when
Panel Replay is disabled with xe.enable_panel_replay=0.
