From fc4c79c37e822719cab447a448af0b48f4a52418 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 12 Oct 2016 10:05:21 +0100 Subject: [PATCH] drm/i915: Consolidate error object printing Leave all the pretty printing to userspace and simplify the error capture to only have a single common object printer. It makes the kernel code more compact, and the refactoring allows us to apply more complex transformations like compressing the output.
