drm/i915/psr: Repeat Selective Update area alignment

2026-03-19T15:08:41Z

commit 1be2fca84f520105413d0d89ed04bb0ff742ab16 upstream. Currently we are aligning Selective Update area to cover cursor fully if needed only once. It may happen that cursor is in Selective Update area after pipe alignment and after that covering cursor plane only partially. Fix this by looping alignment as long as alignment isn't needed anymore. v2: - do not unecessarily loop if cursor was already fully covered - rename aligned as su_area_changed Fixes: 1bff93b8bc27 ("drm/i915/psr: Extend SU area to cover cursor fully if needed") Cc: # v6.9+ Signed-off-by: Jouni Högander Reviewed-by: Ankit Nautiyal Link: https://patch.msgid.link/20260304113011.626542-2-jouni.hogander@intel.com (cherry picked from commit 681e12440d8b110350a5709101169f319e10ccbb) Signed-off-by: Tvrtko Ursulin Signed-off-by: Greg Kroah-Hartman

drm/i915/alpm: ALPM disable fixes

2026-03-19T15:08:33Z

commit eb4a7139e97374f42b7242cc754e77f1623fbcd5 upstream. PORT_ALPM_CTL is supposed to be written only before link training. Remove writing it from ALPM disable. Also clearing ALPM_CTL_ALPM_AUX_LESS_ENABLE and is not about disabling ALPM but switching to AUX-Wake ALPM. Stop touching this bit on ALPM disable.

drm/i915/dp: Fix pipe BPP clamping due to HDR

2026-03-12T11:09:33Z

[ Upstream commit fe26ae6ac8b88fcdac5036b557c129a17fe520d2 ] The pipe BPP value shouldn't be set outside of the source's / sink's valid pipe BPP range, ensure this when increasing the minimum pipe BPP value to 30 due to HDR. While at it debug print if the HDR mode was requested for a connector by setting the corresponding HDR connector property. This indicates if the requested HDR mode could not be enabled, since the selected pipe BPP is below 30, due to a sink capability or link BW limit. v2: - Also handle the case where the sink could support the target 30 BPP only in DSC mode due to a BW limit, but the sink doesn't support DSC or 30 BPP as a DSC input BPP. (Chaitanya) - Debug print the connector's HDR mode in the link config dump, to indicate if a BPP >= 30 required by HDR couldn't be reached. (Ankit) - Add Closes: trailer. (Ankit) - Don't print the 30 BPP-outside of valid BPP range debug message if the min BPP is already > 30 (and so a target BPP >= 30 required for HDR is ensured).

drm/i915/psr: Don't enable Panel Replay on sink if globally disabled

[ Upstream commit 69f83f167463bad26104af7fbc114ce1f80366b0 ] With some panels informing support for Panel Replay we are observing problems if having Panel Replay enable bit set on sink when forced to use PSR instead of Panel Replay. Avoid these problems by not setting Panel Replay enable bit in sink when Panel Replay is globally disabled during link training. I.e. disabled by module parameter. The enable bit is still set when disabling Panel Replay via debugfs interface. Added note comment about this.
