From: Daniel Vetter Date: Thu, 7 Nov 2013 13:49:24 +0000 (+0100) Subject: drm/i915: Fix up the bdw pipe interrupt enable lists X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=30100f2bea6b07940ce3ed777c0c7c1544ea4a15;p=linux-beck.git drm/i915: Fix up the bdw pipe interrupt enable lists - Pipe underrun can't just be enabled, we need some support code like on ilk-hsw to make this happen. So drop it for now. - CRC error is a special mode of the CRC hardware that we don't use, so again drop it. Real CRC support for bdw will be added later. - All the other error bits are about faults, so rename the #define and adjust the output. v2: Use pipe_name as pointed out by Ville. Ville's comment was on a previous patch, but it was easier to squash in here.
