No real reason to have this pxp state computation in intel_atomic_check_planes(). Just stuff it into skl_plane_check(). There was also some funny state copying being done from the old plane state to the new plane state when the plane is anyway disabled. The one thing we presumably must remember to do is copy over the decrypt state when assigning a Y plane for planar YCbCr scanout, so that the Y plane's PLANE_SURF will get the appropriate bit set. The force_black thing should not matter as I'm pretty sure all that stuff is ignored for the Y plane. I suppose this was the reason for the odd placement for the state computation, but I see no reason to deviate from the standard way of doing these things. This also guarantees that we don't calculate things differently between the linked UV and Y plane. v2: Only do stuff for icl+ since 'force_black' depends on the plane CSC which is an icl+ feature Cc: Anshuman Gupta <anshuman.gupta@intel.com> Cc: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Juston Li <juston.li@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Uma Shankar <uma.shankar@intel.com> Signed-off-by:Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211006235704.28894-2-ville.syrjala@linux.intel.com Reviewed-by: Juston Li <juston.li@intel.com> #v1

A new warning in clang points out a place in this file where a bitwise OR is being used with boolean types: drivers/gpu/drm/i915/intel_pm.c:3066:12: warning: use of bitwise '|' with boolean operands [-Wbitwise-instead-of-logical] changed = ilk_increase_wm_latency(dev_priv, dev_priv->wm.pri_latency, 12) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This construct is intentional, as it allows every one of the calls to ilk_increase_wm_latency() to occur (instead of short circuiting with logical OR) while still caring about the result of each call. To make this clearer to the compiler, use the '|=' operator to assign the result of each ilk_increase_wm_latency() call to changed, which keeps the meaning of the code the same but makes it obvious that every one of these calls is expected to happen.

During the review I focused on stop the using of the "+" to reference the newer platforms, but I forgot that we are in a process of making things more clear and differentiate graphics and display versions. So, let me to clean up this a bit. Also, we don't need any version mentioned in the config menu entry, only in the help.

The I915_TILING_* values in our uapi header are intended solely for use with the old get_tiling/set_tiling ioctls that operate on hardware de-tiling fences; all other uapi communication about tiling types is done via framebuffer modifiers rather than with these old values. On newer Intel platforms detiling fences no longer exist so the old get_tiling/set_tiling ioctls are no longer usable and will always return -EOPNOTSUPP. This means there's no reason to add new tiling types (such as the Tile4 format introduced by Xe_HP) to the uapi header here. Any kernel-internal code that needs to represent tiling format should either rely on framebuffer modifiers (as the display code does) or use some kind of non-uapi enum (as the GEM blt selftest now does).

For the time being, neither the power sequencer nor the backlight code properly support two eDP panels simultaneously.

This fix the deadlock with the BO reservations during SVM_BO evictions while allocations in VRAM are concurrently performed. More specific, while the ttm waits for the fence to be signaled (ttm_bo_wait), it already has the BO reserved. In parallel, the restore worker might be running, prefetching memory to VRAM. This also requires to reserve the BO, but blocks the mmap semaphore first. The deadlock happens when the SVM_BO eviction worker kicks in and waits for the mmap semaphore held in restore worker. Preventing signal the fence back, causing the deadlock until the ttm times out. We don't need to hold the BO reservation anymore during validation and mapping. Now the physical addresses are taken from hmm_range_fault. We also take migrate_mutex to prevent range migration while validate_and_map update GPU page table. Signed-off-by:

Limit the supported UHBR rates based on the repeater support, if there are repeaters. This should be done in DP helper level, but that requires an overhaul of the LTTPR handling, as the max rate is not enough to represent how 128b/132b rates may be masked along the way. Curiously, the spec says: * Shall be cleared to 00h when operating in 8b/10b Link Layer. * Each LTTPR on the way back to the DPTX shall clear the bits that do not correspond to the LTTPR's current bit rate. It's rather vague if we can reliably use the field at this time due to the wording "operating" and "current". But it would seem bizarre to have to wait until trying to operate a 128b/132b link layer at a certain bit rate to figure this out. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:
