From 79eee7aa0d4de5a42331c63d3c7c735248b53d0c Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Wed, 26 Sep 2012 12:43:10 +1000 Subject: [PATCH] drm/nvc0/ltcg: mask off intr 0x10 NVIDIA do that at startup too on Fermi, so perhaps the heap of 0x10 intrs we receive are normal and we can ignore them. On Kepler NVIDIA *don't* do this, but the hardware appears to come up with the bit masked off by default - so that's probably why :) This should silence some interrupt spam seen on Fermi+ boards. Backported patch from reworked nouveau kernel tree.
