Before we destroy the context (or exit), how about a query_trtt().
We should also query after create to ensure that the defaults are set.
Just thinking that is better doing the query after several steps (i.e.
the execbuf) rather than immediately after the set in order to give time
for something to go wrong. We should also ensure that everything remains
set after a GPU hang and suspend/resume.
Nice suggestion, currently get-trtt-context will just retrieve the
TR-TT params stored with a Driver for a given context.
Should the Context image itself be read to ensure that settings are
intact or not ?
I'm happy with reading back the driver state (as opposed to the context
image). We're verifying that the hw is setup via the execbuf, we just
want to double check that the kernel reports the correct setup as well.
Fine, will use get-trtt-context only. The trtt params stored with the
Driver should be invariant.
