From: Ben Skeggs Date: Thu, 26 Aug 2010 01:32:01 +0000 (+1000) Subject: drm/nv50: add new accelerated bo move funtion X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f1ab0cc9bacdd33a37603a80852ee0579f809ce7;p=linux-beck.git drm/nv50: add new accelerated bo move funtion Hopefully this one will be better able to cope with moving tiled buffers around without getting them all scrambled as a result.
