From c4266a9c7b0ee66b3d1ca22745d8eb9472e21b4b Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Thu, 1 Oct 2015 11:36:58 +1000 Subject: [PATCH] drm/nouveau/pci/nv46: attempt to fix msi, and re-enable by default Was not able to obtain a trace of NVRM due to kernel version annoyances, however, experimentally confirmed that the WAR we use on NV50/G8x boards works here too.
