In commit d03b224f ("drm/i915/gt: Apply sanitiization just before resume") the GT sanitization was pulled into the resume path as we need to know the backend in order to do a full reset prior to resume. However, it is still imperative that we scrub existing GPU state before clobbering in our early setup, so restore a minimal GPU reset at the start of our init sequence.

Our goal in wait_for_idle (intel_gt_retire_requests) is to the current workload *and* their idle barriers. This requires us to notice the late arrival of those, which is done by inspecting the list of active timelines. However, if a concurrent retirer is running that new timeline may not be added until after we drop the lock -- so flush concurrent retirers before we take the lock and inspect the list.

Due to DDB overlaps the pipe enabling sequence is not always crescent. As the previous patch selects the smallest pipe/transcoder in the MST stream to be master and it needs to be enabled first, this changes were needed to guarantee that. So first lets enable all pipes that do not need a fullmodeset as those don't have any external dependency and those are the ones that can overlap with each other. Then on the second loop it will enable all the pipes that needs a modeset and don't depends on other pipes like MST master pipe/transcoder. Then finally all the pipes that needs a modeset and have dependency on other pipes, that at this point are alread enabled. v3: rebased v4: - added check for modeset_pipes too to decide if is necessary for a wait a vblank - added DDB allocation overlap check for pipes that needs a modeset Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Manasi Navare <manasi.d.navare@intel.com> Reviewed-by:

On TGL the blending of all the streams have moved from DDI to transcoder, so now every transcoder working over the same MST port must send its stream to a master transcoder and master will send to DDI respecting the time slots. So here adding all the CRTCs that shares the same MST stream if needed and computing their state again, it will pick the lowest pipe/transcoder among the ones in the same stream to be master. Most of the time skl_commit_modeset_enables() enables pipes in a crescent order but due DDB overlapping it might not happen, this scenarios will be handled in the next patch. v2: - Using recently added intel_crtc_state_reset() to set mst_master_transcoder to invalid transcoder for all non gen12 & MST code paths - Setting lowest pipe/transcoder as master, previously it was the first one but setting a predictable one will help in future MST e port sync integration - Moving to intel type as much as we can v3: - Now intel_dp_mst_master_trans_compute() returns the MST master transcoder - Replaced stdbool.h by linux/types.h - Skip the connector being checked in intel_dp_mst_atomic_master_trans_check() - Using pipe instead of transcoder to compute MST master v4: - renamed connector_state to conn_state v5: - Improved the parameters of intel_dp_mst_master_trans_compute() to simply code - Added call drm_atomic_add_affected_planes() in intel_dp_mst_atomic_master_trans_check() as helper could not do it for us - Removed "if (ret)" left over from v3 changes v6: - handled ret == I915_MAX_PIPES case in compute BSpec: 50493 BSpec: 49190 Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by:

intel_connector_needs_modeset() will be used outside of intel_display.c in a future patch so it would only be necessary to remove the state and add the prototype to the header file.

Gen-12 display decompression operates on Y-tiled compressed main surface. The CCS is linear and has 4 bits of metadata for each main surface cache line pair, a size ratio of 1:256. Gen-12 display decompression is incompatible with buffers compressed by earlier GPUs, so make use of a new modifier to identify gen-12 compression. Another notable change is that render decompression is supported on all planes except cursor and on all pipes. Start by adding render decompression support for [A,X]BGR888 pixel formats. v2: Fix checkpatch warnings (Lucas) v3: Rebase, disable color clear, styling changes and modify intel_tile_width_bytes and intel_tile_height to handle linear CCS v4: - Use format block descriptors and the i915 specific func to get the subsampling for each color plane. - Use helpers to convert between CCS and main planes. v5: - Fix subsampling returned by intel_fb_plane_get_subsampling() for the CCS plane of the first plane. v6: - Rebased on v2 of patch 4. v7: - Fix plane dimensions during FB check.

Using helpers instead of open coding this to select a CCS plane for a main plane makes the code cleaner and less error-prone when the location of CCS plane can be different based on the format (packed vs. YUV semiplanar). The same applies to selecting an AUX plane which can be a UV plane (for an uncompressed YUV semiplanar format), or a CCS plane.
