* drm/i915: Constify intel_pipe_config_compare()Ville Syrjälä2019-06-181-26/+17
| | | | | | | | | | Now that intel_pipe_config_compare() no longer clobbers the passed in state we can make both crtc states const. And while at we simplify the calling convention, and clean up intel_compare_link_m_n() a bit.

* drm/i915: Don't clobber M/N values during fastset checkVille Syrjälä2019-06-181-8/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | We're now calling intel_pipe_config_compare(..., true) uncoditionally which means we're always going clobber the calculated M/N values with the old values if the fuzzy M/N check passes. That causes problems because the fuzzy check allows for a huge difference in the values. I'm actually tempted to just make the M/N checks exact, but that might prevent fastboot from kicking in when people want it. So for now let's overwrite the computed values with the old values only if decide to skip the modeset. v2: Copy has_drrs along with M/N M2/N2 values Cc: stable@vger.kernel.org Cc: Blubberbub@protonmail.com Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Hans de Goede <hdegoede@redhat.com> Tested-by: Blubberbub@protonmail.com Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=110782 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=110675 Fixes: d19f958db23c ("drm/i915: Enable fastset for non-boot modesets.")

* drm/i915: Use drm_gem_object.resvChris Wilson2019-06-181-3/+3
| | | | | | | | | | | | | | | Since commit 1ba627148ef5 ("drm: Add reservation_object to drm_gem_object"), struct drm_gem_object grew its own builtin reservation_object rendering our own private one bloat. Remove our redundant reservation_object and point into obj->base.resv instead.

* drm/i915/ehl: Introduce Mule Creek Canyon PCHMatt Roper2019-06-174-4/+50
| | | | | | | | | | | Although EHL introduces a new PCH, the South Display part of the PCH that we care about is nearly identical to ICP, just with some pins remapped. Most notably, Port C is mapped to the pins that ICP uses for TC Port 1.

| | | | | | | | | | | | | | | | | | | | | | | Now that we have a new subdirectory for display code, continue by moving modesetting core code. display/intel_frontbuffer.h sticks out like a sore thumb, otherwise this is, again, a surprisingly clean operation. v2: - don't move intel_sideband.[ch] (Ville) - use tabs for Makefile file lists and sort them Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Acked-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Acked-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Acked-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190613084416.6794-3-jani.nikula@intel.com
