From f589be88caf32501a734e531180d5df5d6089ef3 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Sun, 22 Jul 2012 11:55:54 +1000 Subject: [PATCH] drm/nouveau/pageflip: kick flip handling out of engsw and into fence This is all very much a policy thing, and hence will not belong in SW after the rework. engsw now only handles receiving the event to say "can flip now" and makes a callback to perform the actual work.
