Generic comment on this patch set. Maybe we should add one more patch
with "Fixes" tag:
Fixes: e60cff453b82 ("drm/i915/dp: Enable DP tunnel BW allocation
mode")
Cc: Imre Deak <[email protected]>
Cc: <[email protected]> # v6.9+
This patch would just add:
if (intel_dp_tunnel_bw_alloc_is_enabled(intel_dp)) {
drm_dbg_kms(display->drm,
"Panel Replay is disabled as DP tunneling
enabled\n");
return false;
}
into _panel_replay_compute_config. this could be first patch in your
set. What do you think?
