2020-09-17drm/i915: Extract intel_hdmi_has_audio()Ville Syrjälä
Pull the "do we want to enable audio?" computation into a small helper to make intel_hdmi_compute_config() less messy. Will make it easier to add more checks for this later (eg. we should actually be checking at the hblank is long enough for audio transmission).

2020-09-15drm/i915: Reduce INTEL_DISPLAY_ENABLED to just removing the outputsVille Syrjälä
Having a mode where the display hardware is present but we try to pretend it isn't just leads to massive headaches when trying to reason what the fallout might be from skipping some random bits of programming. Let's just neuter INTEL_DISPLAY_ENABLED so that we treat the hardware as fully present, except we just don't register any outputs. That's still rather sketchy if the outputs are already enabled when the driver is loaded. I think the simplest solution would be to probe everything as normal and just return disconnected" from all .detect() hooks. That would avoid anything automagically enabling those outputs, but the driver could then shut things down using the normal codepaths.

Logically part of the display save/restore. No functional changes. Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200910095227.9466-2-jani.nikula@intel.com
2020-09-11drm/i915: disable all display features when no displayJani Nikula
Disable all display feature flags when there are no pipes i.e. there is no display. This should help with not having to additionally check for HAS_DISPLAY() when a feature flag check would suffice. Also disable modeset and atomic driver features.

2020-09-10drm/i915: Fix slightly botched merge in __reloc_entry_gpuMaarten Lankhorst
This function should be an int, not a bool. Presumably because we had the same 2 reverts in a slightly different way, git got confused. Thanks to Dan for reporting. :) The conflict is between the 3 reverts in drm-fixes: 4993a8a37808 ("Revert "drm/i915: Remove i915_gem_object_get_dirty_page()"") ad5d95e4d538 ("Revert "drm/i915/gem: Async GPU relocations only"") 20561da3a2e1 ("Revert "drm/i915/gem: Delete unused code"") And the slightly different combined revert in drm-intel-gt-next, but with the same goal: 102a0a9051f4 ("Revert "drm/i915/gem: Async GPU relocations only"") In the merge commit 1f4b2aca794f ("Merge tag 'drm-intel-gt-next-2020-09-07' of git://anongit.freedesktop.org/drm/drm-intel into drm-next") things went wrong, but the merge commit view now doesn't show any conflict anymore (as git tends to do when the resolution picks one or the other branch). The need to handle other than just true/false error codes in __reloc_entry_gpu was added in the dma_resv locking changes in c43ce12328df ("drm/i915: Use per object locking in execbuf, v12.")
