Eeek.. let's try and not make the request tracing ability even more useless.
Because for trace.pl the decoupled from actual request completion nature
of dma_fence_signaled is depressing enough. I wonder how better tracing
tools view/cope with this.
And I'd also write to Santa to wire me up a real request start, to
distinguish semaphores vs batch execution. In the realm of impossible
wishes yeah.
Persistent breadcrumbs while tracing is another one for which even there
was a patch some time back.
Regards,
Tvrtko
