From a1c930789aa51b928f804c9186f9821efd070ce1 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Fri, 19 May 2017 23:59:34 +1000 Subject: [PATCH] drm/nouveau/disp: introduce object to track per-head functions/state Primarily intended as a way to pass per-head state around during supervisor handling, and share logic between NV50/GF119.
