From 973f10c2d3ea4cca2f359353812fb93d8c43652f Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Fri, 4 Nov 2016 17:20:36 +1000 Subject: [PATCH] drm/nouveau/kms/nv50: separate out base channel commit This commit separates the calculation of EVO state from the commit, in order to make the same code useful for atomic modesetting. The legacy interfaces have been wrapped on top of them.
