From: Ville Syrjälä Date: Mon, 27 Mar 2017 18:55:35 +0000 (+0300) Subject: drm/i915: Clean up cursor junk from intel_crtc X-Git-Tag: v4.14-rc1~484^2~32^2~90 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cd5dcbf1b26c60dfa8fd8628fd2fcf3d33877c63;p=platform%2Fkernel%2Flinux-rpi.git drm/i915: Clean up cursor junk from intel_crtc Move cursor_base, cursor_cntl, and cursor_size from intel_crtc into intel_plane so that we don't need the crtc for cursor stuff so much. Also entirely nuke cursor_addr which IMO doesn't provide any benefit since it's not actually used by the cursor code itself. I'm not 100% sure what the SKL+ DDB is code is after by looking at cursor_addr so I just make it do its checks unconditionally. If that's not correct then we should likely replace it with somehting like plane_state->visible.
