drm/i915: Kill intel_crtc->cursor_bo
The vma may have been rebound between the last time the cursor was enabled and now, so skipping the cursor gtt offset deduction is not safe unless we would also reset cursor_bo to NULL when disabling the cursor. Just thow cursor_bo to the bin instead since it's lost all other uses thanks to universal plane support. Chris pointed out that cursor updates are currently too slow via universal planes that micro optimizations like these wouldn't even help. v2: Add a note about futility of micro optimizations (Chris) Cc: drm-intel-fixes@lists.freedesktop.org References: http://lists.freedesktop.org/archives/intel-gfx/2015-December/082976.html Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Takashi Iwai <tiwai@suse.de> Cc: Jani Nikula <jani.nikula@linux.intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1450107302-17171-1-git-send-email-ville.syrjala@linux.intel.com Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> (cherry picked from commit 1264859d648c4bdc9f0a098efbff90cbf462a075) Signed-off-by: Jani Nikula <jani.nikula@intel.com>
