From: Ville Syrjälä Date: Fri, 5 Jul 2013 08:57:13 +0000 (+0300) Subject: drm/i915: Add scaled paramater to update_sprite_watermarks() X-Git-Tag: firefly_0821_release~176^2~5263^2~73^2~87 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=bdd57d0386d892e5c470a3d615c3034389700964;p=firefly-linux-kernel-4.4.55.git drm/i915: Add scaled paramater to update_sprite_watermarks() For calculating watermarks we want to know whether sprites are scaled. Pass that information to update_sprite_watermarks() so that eventually we may do some watermark pre-computing.
