Hi Dave and Sima, Here goes our likely last drm-intel-next PR towards 6.16.
Mostly with patches targeting the full display split. Thanks, Rodrigo. drm-intel-next-2025-05-08: Non-display related: - Fix undefined reference to `intel_pxp_gsccs_is_ready_for_sessions' Display related: - More work towards display separation (Jani) - Stop writing VRR_CTL_IGN_MAX_SHIFT for MTL onwards (Jouni) - DSC checks for 3 engines (Ankit) - Add link rate and lane count to i915_display_info (Khaled) - PSR fixes and workaround for underrun on idle (Jouni) - LOBF enablement and ALMP fixes (Animesh) - Clean up VGA plane handling (Ville) - Use an intel_connector pointer everywhere (Imre) - Fix warning for coffeelake on SunrisePoint PCH (Jiajia) - Rework/Correction on minimum hblank calculation (Arun) - Dmesg clean up (Jani) - Add a couple of simple display workarounds (Ankit, Vinod) - Refactor HDCP GSC (Jani) The following changes
