Dhinakaran Pandiyan 07bcd99b80 drm/i915/frontbuffer: Pull frontbuffer_flush out of gem_obj_pin_to_display ... i915_gem_obj_pin_to_display() calls frontbuffer_flush with origin set to DIRTYFB. The callers however are at a vantage point to decide if hardware frontbuffer tracking can do the flush for us. For example, legacy cursor updates, like flips, write to MMIO registers, which then triggers PSR flush by the hardware. Moving frontbuffer_flush out will enable us to skip a software initiated flush by setting origin to FLIP. Thanks to Chris for the idea. v2: Rebased due to Ville adding intel_plane_pin_fb(). Minor code reordering as fb_obj_flush doesn't need struct_mutex (Chris) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180307033420.3086-1-dhinakaran.pandiyan@intel.com		2018-03-13 13:49:39 -07:00
