Others should be preserved across suspend. BUT they are not context saved
(I Know!) so any sort of dirty test won't work. The current test will
check the other engines values as they are programmed on start-up (with
the new patches) and should be preserved (or be reprogrammed) when coming
out of *C6/Suspend/Hibernate.
So context save/resume only needs to be tested for the RCS engine. For
Now.

As well as checking for creating new contexts after resume, we also need
to check that the register values are preserved across suspend (i.e.
that the register state is being saved back into the context image and
then restored).
Ok, I'll add another test case that does this for the render engine
(the only one that is effected (at the moment) by context save and
resume.
We do expect that the mocs values for other rings to be preserved across
suspend. Or did I misunderstand you? i.e create-context; bcs; suspend;
bcs should^W must work.
