* drm/i915: stop including i915_irq.h from i915_trace.hJani Nikula2022-11-111-0/+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.

* drm/i915/trace: split out display trace to a separate fileJani Nikula2021-12-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. There should be no changes to tracepoints. v3: - Rebase v2: - Define TRACE_INCLUDE_PATH relative to define_trace.h (Chris) - Remove useless comments (Ville) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/7862ad764fbd0748d903c76bc632d3d277874e5b.1638961423.git.jani.nikula@intel.com

In order to avoid exposing intel_disable_ddi_buf() outside intel_ddi.c we can just open code the DDI_BUF_CTL write. The enable side already has all that stuff open coded so this actually is more symmetric. But we do need to remeber to bring the intel_wait_ddi_buf_idle() call over from inside intel_disable_ddi_buf().

| | | | | | | | | | | | | | | | | | PIPECONF becamse TRANSCONF when HSW introduced the EDP transcoder. Bigjoiner is making life even more confusing by introducing a N:1 relationship between pipes and transcoders. In that case we only enable/configure the transcoder corresponding to the master pipe. Let's do some renames to make it clear we're dealing with the transcoder rather than pipe when it comes to PIPECONF/TRANSCONF. I decided to leave the _cpu_ part out from the function/macro names since the PCH transcoder related stuff already has a _pch_ in their name. So shouldn't be possible to confuse them.
