2022-02-15drm/i915: Introduce intel_crtc_is_bigjoiner_{slave,master}()Ville Syrjälä

Add display/intel_display_trace.[ch] for defining display tracepoints. The main goal is to reduce cross-includes between gem and display. It would be possible split up tracing even further, but that would lead to more boilerplate. We end up having to include intel_crtc.h in a few places because it was pulled in implicitly via intel_de.h -> i915_trace.h -> intel_crtc.h, and that's no longer the case.

2021-06-22drm/i915/dsc: abstract helpers to get bigjoiner primary/secondary crtcJani Nikula
Add a single point of truth for figuring out the primary/secondary crtc for bigjoiner instead of duplicating the magic pipe +/- 1 in multiple places. Also fix the pipe validity checks to properly take non-contiguous pipes into account. The current checks may theoretically overflow i915->pipe_to_crtc_mapping[pipe], albeit with a warning, due to fused off pipes, as INTEL_NUM_PIPES() returns the actual number of pipes on the platform, and the check is for INTEL_NUM_PIPES() == pipe + 1.

2019-12-19drm/i915/dsc: fix DSC power domains for DSIJani Nikula
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.
