From 8ad6a539db436d682c423fc7188a759400b238b4 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 1 Mar 2019 14:03:47 +0000 Subject: drm/i915: Fix I915_EXEC_RING_MASK commit d90c06d57027203f73021bb7ddb30b800d65c636 upstream. 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.
