 * With full ppgtt enabled each process using drm will allocate at least one
 * translation table. With these traces it is possible to keep track of the
 * allocation and of the lifetime of the tables; this can be used during
 * testing/debug to verify that we are not leaking ppgtts.
 * These traces identify the ppgtt through the vm pointer, which is also printed
 * by the i915_vma_bind and i915_vma_unbind tracepoints.
