From 6d2b888569d366beb4be72cacfde41adee2c25e1 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 7 Aug 2013 18:30:54 +0100 Subject: [PATCH] drm/i915: List objects allocated from stolen memory in debugfs I was curious as to what objects were currently allocated from stolen memory, and so exported it from debugfs.
