drm/i915/display: Store compressed bpp in U6.4 format DSC parameter bits_per_pixel is stored in U6.4 format. The 4 bits represent the fractional part of the bpp. Currently we use compressed_bpp member of dsc structure to store only the integral part of the bits_per_pixel. To store the full bits_per_pixel along with the fractional part, compressed_bpp is changed to store bpp in U6.4 formats. Intergral part is retrieved by simply right shifting the member compressed_bpp by 4. v2: -Use to_bpp_int, to_bpp_frac_dec, to_bpp_x16 helpers while dealing with compressed bpp. (Suraj) -Fix comment styling. (Suraj) v3: -Add separate file for 6.4 fixed point helper(Jani, Nikula) -Add comment for magic values(Suraj) v4: -Fix checkpatch warnings caused by renaming(Suraj) v5: -Rebase. -Use existing helpers for conversion of bpp_int to bpp_x16 and vice versa.

drm/i915: stop including i915_irq.h from i915_trace.h 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.

drm/i915: Change bigjoiner state tracking to use the pipe bitmask Get rid of the inflexible bigjoiner_linked_crtc pointer thing and just track things as a bitmask of pipes instead. We can also nuke the bigjoiner_slave boolean as the role of the pipe can be determined from its position in the bitmask. It might be possible to nuke the bigjoiner boolean as well if we make encoder.compute_config() do the bitmask assignment directly for the master pipe. But for now I left that alone so that encoer.compute_config() will just flag the state as needing bigjoiner, and the intel_atomic_check_bigjoiner() is still responsible for determining the bitmask. But that may have to change as the encoder may be in the best position to determine how exactly we should populate the bitmask. Most places that just looked at the single bigjoiner_linked_crtc now iterate over the whole bitmask, eliminating the singular slave pipe assumption.

drm/i915/xelpd: Add XE_LPD power wells Aside from the hardware-managed PG0, XE_LPD has power wells 1-2 and A-D. These power wells should be enabled/disabled according to the following dependency tree (enable top to bottom, disable bottom to top): PG0 | --PG1-- / \ PGA --PG2-- / | \ PGB PGC PGD PWR_WELL_CTL follows the general ICL/TGL design and places PG A-D in the bits that would have been PG 6-9 under the old scheme.

drm/i915/dsc: fix DSC power domains for DSI Fix several issues with DSC power domains that did not take DSI transcoders into account: - On TGL+ we need to use PW2 for DSC on pipe A, not transcoder A. There is no longer an eDP transcoder, but there are two DSI transcoders which may be connected to pipe A. - On TGL+ we need to use the pipe, not transcoder, power domains for DSC on pipes other than A. Again, there are DSI transcoders. - On ICL we need to use PW2 for DSC also for DSI transcoders, not just for the eDP transcoder. Using is_pipe_dsc() also adds the warning about ICL pipe A DSC, which does not exist.

drm/i915/dsc: clarify DSC support for pipe A on ICL The check for cpu_transcoder != TRANSCODER_A is more magic than necessary, and potentially misleading. Before TGL, DSC is supported on pipe A if, and only if, it's used with eDP or DSI transcoders. No functional changes.
