[Intel-gfx] [PATCH] drm/i915: Fix dynamic allocation of physical handles

2014-05-21 Thread Chris Wilson
A single object may be referenced by multiple registers fundamentally breaking the static allotment of ids in the current design. When the object is used the second time, the physical address of the first assignment is relinquished and a second one granted. However, the hardware is still reading (a
