From 6bbab3b6b65669b974bece5a688b3dba49ea3e06 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/ovly channel usage bounds 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. We're no longer touching the overlay channel usage bounds as of this commit. The code to do so is in place for when overlay planes are added.
