On ADL+ the hardware automagically calculates the CCS AUX surface stride from the main surface stride, so when remapping we can't really play a lot of tricks with the main surface stride, or else the AUX surface stride would get miscalculated and no longer match the actual data layout in memory. Supposedly we could remap in 256 main surface tile units (AUX page(4096)/cachline(64)*4(4x1 main surface tiles per AUX cacheline)=256 main surface tiles), but the extra complexity is probably not worth the hassle. So let's just make sure our mapping stride is calculated from the full framebuffer stride (instead of the framebuffer width). This way the stride we program into PLANE_STRIDE will be the original framebuffer stride, and thus there will be no change to the AUX stride/layout.

Xe needs intel_fb_bo_framebuffer_fini for taking care of unpinning the fb and taking reference. In i915 this can be empty. Also move intel_frontbuffer_get to be done after intel_fb_bo_framebuffer_init to have reasonable sequences: intel_fb_bo_framebuffer_init intel_frontbuffer_get ... intel_frontbuffer_put intel_fb_bo_framebuffer_fini v2: Empty function instead of define Signed-off-by:

The uncore code may not always be available (e.g. when we build the display code with Xe), so we can't always rely on having the uncore's spinlock. To handle this, split the spin_lock/unlock_irqsave/restore() into spin_lock/unlock() followed by a call to local_irq_save/restore() and create wrapper functions for locking and unlocking the uncore's spinlock. In these functions, we have a condition check and only actually try to lock/unlock the spinlock when I915 is defined, and thus uncore is available. This keeps the ifdefs contained in these new functions and all such logic inside the display code.

plane_view_scanout_stride() currently assumes that we had to pad the mapping stride with dummy pages in order to align it. But that is not the case if the original fb stride exceeds the aligned stride used to populate the remapped view, which is calculated from the user specified framebuffer width rather than the user specified framebuffer stride. Ignore the original fb stride in this case and just stick to the POT aligned stride. Getting this wrong will cause the plane to fetch the wrong data, and can lead to fault errors if the page tables at the bogus location aren't even populated. TODO: figure out if this is OK for CCS, or if we should instead increase the width of the view to cover the entire user specified fb stride instead...

Apparently some BXT/GLK systems have DSI panels whose timings don't agree with the normal cpu transcoder hblank>=32 limitation. This is perhaps fine as there are no specific hblank/etc. limits listed for the BXT/GLK DSI transcoders. Move those checks out from the global intel_mode_valid() into into connector specific .mode_valid() hooks, skipping BXT/GLK DSI connectors. We'll leave the basic [hv]display/[hv]total checks in intel_mode_valid() as those seem like sensible upper limits regardless of the transcoder used.

Currently we are enabling selective fetch for all planes that are visible. This is suboptimal as we might be fetching for memory for planes that are not part of selective update. Fix this by adding proper handling for disabling plane selective fetch: If plane previously part of selective update is now not part of update: Add it into updated planes and let the plane configuration to disable selective fetch for it. v3: Checkpatch warnings fixed v2: - Add setting sel_fetch_area->y1/y2 to -1 - Remove setting again local sel_fetch_area variable Signed-off-by:

The current implementation of change_lut_val_precision() is just a convoluted way of shifting by 8. Implement the proper rounding by just using drm_color_lut_extract() and intel_color_lut_pack() like everyone else does. And as the uapi can't handle >=1.0 values but the hardware can we need to clamp the results appropriately in the readout path. Signed-off-by:

-
Ville Syrjälä authored
The current implementation of drm_color_lut_extract() generates weird results. Eg. if we go through all the values for 16->8bpc conversion we see the following pattern: in out (count) 0 - 7f -> 0 (128) 80 - 17f -> 1 (256) 180 - 27f -> 2 (256) 280 - 37f -> 3 (256) ... fb80 - fc7f -> fc (256) fc80 - fd7f -> fd (256) fd80 - fe7f -> fe (256) fe80 - ffff -> ff (384) So less values map to 0 and more values map 0xff, which doesn't seem particularly great. To get just the same number of input values to map to the same output values we'd just need to drop the rounding entrirely. But perhaps a better idea would be to follow the OpenGL int<->float conversion rules, in which case we get the following results: in out (count) 0 - 80 -> 0 (129) 81 - 181 -> 1 (257) 182 - 282 -> 2 (257) 283 - 383 -> 3 (257) ... fc7c - fd7c -> fc (257) fd7d - fe7d -> fd (257) fe7e - ff7e -> fe (257) ff7f - ffff -> ff (129) Note that since the divisor is constant the compiler is able to optimize away the integer division in most cases. The only exception is the _ULL() case on 32bit architectures since that gets emitted as inline asm via do_div() and thus the compiler doesn't get to optimize it. Signed-off-by:
