From f87cd8b695d372087685976460fac1ec6ba2fca9 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Sun, 19 Jan 2014 04:18:15 -0500 Subject: [PATCH] drm/nouveau/devinit: lock/unlock crtc regs for all devices, not just pre-nv50 Also make nv_lockvgac work for nv50+ devices. This should fix IO_CONDITION and related VBIOS opcodes that read/write the crtc regs.
