drm/i915: Add tracepoints to track a vm during its lifetime
- ppgtt init/release: these tracepoints are useful for observing the creation and destruction of Full PPGTTs. - ctx create/free: we can use the ctx_free trace in combination with the ppgtt_release one to be sure that the ppgtt doesn't stay alive for too long after the ctx is destroyed. ctx_create is there for simmetry - switch_mm: important point in the lifetime of the vm v4: add DOC information v5: pull the DOC in drm.tmpl v6: clean ppgtt init/release traces + add ctx create/free and switch_mm tracepoints (Chris) v7: drop execlist_submit_context tracepoint Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
