2024-08-23drm/i915/sprite: convert to struct intel_displayJani Nikula1-97/+112
Going forward, struct intel_display shall replace struct drm_i915_private as the main display device data pointer type. Convert intel_sprite.[ch] to struct intel_display.

2024-06-24drm/i915: Introduce the plane->min_alignment() vfuncVille Syrjälä1-0/+2
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.

2022-11-11drm/i915: stop including i915_irq.h from i915_trace.hJani Nikula1-0/+1
Turns out many of the files that need i915_reg.h get it implicitly via {display/intel_de.h, gt/intel_context.h} -> i915_trace.h -> i915_irq.h -> i915_reg.h. Since i915_trace.h doesn't actually need i915_irq.h, makes sense to drop it, but that requires adding quite a few new includes all over the place. Prefer including i915_reg.h where needed instead of adding another implicit include, because eventually we'll want to split up i915_reg.h and only include the specific registers at each place. Also some places actually needed i915_irq.h too.

Chop vlv_sprite_update() into two halves. Fist half becomes the _noarm() variant, second part the _arm() variant. Fortunately I have already previously grouped the register writes into roughtly the correct order, so the split looks surprisingly clean. Looks like most of the hardware logic was copied from the pre-ctg sprite C, so SPSTRIDE/POS/SIZE are armed by SPSURF, while the rest are self arming. SPCONSTALPHA is the one entirely new register that didn't exist in the old sprite C, and looks like that one is self arming. The CHV pipe B CSC is also self arming, like the rest of the CHV pipe B additions. I didn't have time to capture i915_update_info numbers for these, but since all the other platforms generally showed improvements, and crucially no regression, I am fairly confident this should behave similarly.

2021-11-04drm/i915: Split update_plane() into update_noarm() + update_arm()Ville Syrjälä1-21/+23
The amount of plane registers we have to write has been steadily increasing, putting more pressure on the vblank evasion mechanism and forcing us to increase its time budget. Let's try to take some of the pressure off by splitting plane updates into two parts: 1) write all non-self arming plane registers, ie. the registers where the write actually does nothing until a separate arming register is also written which will cause the hardware to latch the new register values at the next start of vblank 2) write all self arming plane registers, ie. registers which always just latch at the next start of vblank, and registers which also arm other registers to do so Here we just provide the mechanism, but don't actually implement the split on any platform yet. so everything stays now in the _arm() hooks. Subsequently we can move a whole bunch of stuff into the _noarm() part, especially in more modern platforms where the number of registers we have to write is also the greatest. On older platforms this is less beneficial probably, but no real reason to deviate from a common behaviour. And let's sprinkle some TODOs around the areas that will need adapting.

2021-10-29drm/i915/fb: Fold modifier CCS type/tiling attribute to plane capsImre Deak1-1/+1
By using the modifier plane capability flags to encode the modifiers' CCS type and tiling attributes, it becomes simpler to the check for any of these capabilities when providing the list of supported modifiers. This also allows distinguishing modifiers on future platforms where platforms with the same display version support different modifiers. An example is DG2 and ADLP, both being D13, where DG2 supports only F and X tiling, while ADLP supports only Y and X tiling. With the INTEL_PLANE_CAP_TILING_* flags added in this patch we can provide the correct modifiers for each platform. v2: - Define PLANE_HAS_* with macros instead of an enum. (Jani) - Rename PLANE_HAS_*_ANY to PLANE_HAS_*_MASK. (Jani) - Rename PLANE_HAS_* to INTEL_PLANE_CAP_*. - Set the CCS_RC_CC cap only for DISPLAY_VER >= 12. - Set the TILING_Y cap only for DISPLAY_VER < 13 || ADLP. - Simplify the SKL plane cap display version checks and move them to a separate function.

Add a table describing all the framebuffer modifiers used by i915 at one place.

While at it drop the cursor plane filtering from skl_plane_has_rc_ccs(), as the cursor plane is registered with DRM core elsewhere. v1: Unchanged. v2: - Keep the plane caps calculation in the plane code and pass an enum with these caps to intel_fb_get_modifiers().

2021-03-29drm/i915: Unify the FB and plane state view information into one structImre Deak1-13/+13
To allow the simplification of FB/plane view computation in the follow-up patches, unify the corresponding state in the intel_framebuffer and intel_plane_state structs into a new intel_fb_view struct. This adds some overhead to intel_framebuffer as the rotated view will have now space for 4 color planes instead of the required 2 and it'll also contain the unused offset for each color_plane info. Imo this is an acceptable trade-off to get a simplified way of the remap computation. Use the new intel_fb_view struct for the FB normal view as well, so (in the follow-up patches) we can remove the special casing for normal view calculation wrt. the calculation of remapped/rotated views. This also adds an overhead to the intel_framebuffer struct, as the gtt remap info and per-color plane offset/pitch is not required for the normal view, but imo this is an acceptable trade-off as above. The per-color plane pitch filed will be used by a follow-up patch, so we can retrieve the pitch for each view in the same way. No functional changes in this patch. v2: - Make the patch have _no functional change_.

2021-01-29drm/i915: Limit plane stride to below TILEOFF.x limitVille Syrjälä1-6/+27
Limit pre-skl plane stride to below 4k or 8k pixels (depending on the platform). We do this in order guarantee that TILEOFF/OFFSET.x does not get too big. Currently this is not a problem as we align SURF to 4k, and so TILEOFF/OFFSET only have to deal with a single tile's worth of pixels. But for async flips we're going to have to bump SURF alignment to 256k, and thus we can no longer guarantee TILEOFF/OFFSET.x will stay within acceptable bounds. We can avoid this by borrowing a trick from the skl+ code and limit the max plane stride to whatever value we can fit into TILEOFF/OFFSET.x. The slight downside is that we may end up doing GTT remapping in a few more cases where previously we did not have to. But since that will only happen with huge buffers I'm not really concerned about it.

2021-01-28drm/i915/display: Prevent double YUV range correction on HDR planesAndres Calderon Jaramillo1-55/+10
Prevent the ICL HDR plane pipeline from performing YUV color range correction twice when the input is in limited range. This is done by removing the limited-range code from icl_program_input_csc(). Before this patch the following could happen: user space gives us a YUV buffer in limited range; per the pipeline in [1], the plane would first go through a "YUV Range correct" stage that expands the range; the plane would then go through the "Input CSC" stage which would also expand the range because icl_program_input_csc() would use a matrix and an offset that assume limited-range input; this would ultimately cause dark and light colors to appear darker and lighter than they should respectively. This is an issue because if a buffer switches between being scanned out and being composited with the GPU, the user will see a color difference. If this switching happens quickly and frequently, the user will perceive this as a flickering.
