From: Chris Wilson Date: Fri, 1 Mar 2019 14:03:47 +0000 (+0000) Subject: drm/i915: Fix I915_EXEC_RING_MASK X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d90c06d57027;p=openwrt%2Fstaging%2Fblogic.git drm/i915: Fix I915_EXEC_RING_MASK This was supposed to be a mask of all known rings, but it is being used by execbuffer to filter out invalid rings, and so is instead mapping high unused values onto valid rings. Instead of a mask of all known rings, we need it to be the mask of all possible rings.
