2024-06-27drm/i915/dsb: Try to document that DSB_STATUS bit 16 is level triggeredVille Syrjälä
DSB_STATUS bit 16 is supposed to be a sticky bit informing us whether the DSB was idle or not when the pipe's delayed vblank (when double buffered registers latch) occurred. Unfortunately it turns out this is a level triggred signal, ie. the bit will be set whenever the DSB is busy during the scanline window between start of delayed vblank and vtotal. Try to document that fact by renaming the bit. Sadly this also thwarts my plan to use this bit to sanity check that the (to be introduced) DSB based vblank evasion did its job correctly. That would require an edge triggered signal instead.

2024-06-24drm/i915: Use the same vblank worker for atomic unpinMaarten Lankhorst

Any trick I attempted to keep the atomic commit alive didn't work, as drm_atomic_helper_setup_commit() force throttles on any old commit that wasn't cleaned up. The only option remaining is to remove the plane from the atomic commit, and use the same path as the legacy cursor update to clean the state after vblank.

2024-06-24drm/i915: Use vblank worker to unpin old legacy cursor fb safelyVille Syrjälä
The cursor hardware only does sync updates, and thus the hardware will be scanning out from the old fb until the next start of vblank. So in order to make the legacy cursor fastpath actually safe we should not unpin the old fb until we're sure the hardware has ceased accessing it. The simplest approach is to just use a vblank work here to do the delayed unpin. Not 100% sure it's a good idea to put this onto the same high priority vblank worker as eg. our timing critical gamma updates. But let's keep it simple for now, and it we later discover that this is causing problems we can think about adding a lower priority worker for such things.

2024-06-24drm/i915: Nuke the TGL+ chroma plane tile row alignment stuffVille Syrjälä
I don't think the display hardware really has such chroma plane tile row alignment requirements as outlined in commit d156135e6a54 ("drm/i915/tgl: Make sure a semiplanar UV plane is tile row size aligned") Bspec had the same exact thing to say about earlier hardware as well, but we never cared and things work just fine. The one thing mentioned in that commit that is definitely true however is the fence alignment issue. But we don't deal with that on earlier hardware either. We do have code to deal with that issue for the first color plane, but not the chroma planes. So I think if we did want to check this more extensively we should do it in the same places where we already check the first color plane (namely convert_plane_offset_to_xy() and intel_fb_bo_framebuffer_init()).

2024-06-24drm/i915: Introduce fb->min_alignmentVille Syrjälä
Different planes could have different alignment requirements even for the same format/modifier. Collect the alignment requirements across all planes capable of scanning out the fb such that the alignment is satisfactory to all those planes. So far this was sort of handled by making sure intel_surf_alignment() declares the superset of all planes' alignment requirements, but maintaining that manually is annoying. So we're going to move towards each plane declaring only its own requirements, and thus we need code to generate the superset. v2: Drop the borked per-plane vma optimization (Imre) Assert that the plane's declared alignment is POT (Imre) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240612204712.31404-5-ville.syrjala@linux.intel.com Reviewed-by: Imre Deak <imre.deak@intel.com>
2024-06-24drm/i915: Introduce the plane->min_alignment() vfuncVille Syrjälä
Different hardware generations have different scanout alignment requirements. Introduce a new vfunc that will allow us to make that distinction without horrible if-ladders. For now we directly plug in the existing intel_surf_alignment() and intel_cursor_alignment() functions. For fbdev we (temporarily) introduce intel_fbdev_min_alignment() that simply queries the alignment from the primary plane of the first crtc.

Use the suspend encoders helper which is also used by the i915 driver.
