From fc1584059d6c438b1febafa1c207ae1d3c6643e8 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 25 Nov 2016 13:17:18 +0000 Subject: drm/i915: Integrate i915_sw_fence with debugobjects Add the tracking required to enable debugobjects for fences to improve error detection in BAT. The debugobject interface lets us track the lifetime and phases of the fences even while being embedded into larger structs, i.e. to check they are not used after they have been released. v2: Don't populate the stubs, debugobjects checks for a NULL pointer and treats it equivalently.
