From c67a17e972913e03e37d9f55d3bcd7bfc0404a37 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 19 Mar 2014 13:45:46 +0000 Subject: [PATCH] drm/i915: Print how many objects are shared in per-process stats The point of this measure is to gauge why a process has a lot of gem objects in uses and why. Especially for compositors it's interesting to know whether it's a leak of private objects or just a lot of use from buffers shared with clients.
