From 92d68ed7e57e5534c8c82ab28da194b73acb2710 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 19 Apr 2012 17:55:23 +0100 Subject: [PATCH] drm/i915: Remove i915_gem_ringbuffer_(data|info) from debugfs This was originally used as an attempt to diagnose GPU hangs, but was never very reliable and superseded by the i915_error_state capture on hangcheck. It now lies languishing unused and unwanted.
