Looks ok to me... I was trying to double check but dif didn't boot on
bsw. Sigh.

So instead I removed vcs1 from bdw, and vcs0 continues to work.
What is still incorrect though:
$ ./build/tests/gem_exec_parallel --list-subtests
...
vcs0
vcs0-contexts
vcs0-fds
vcs1
vcs1-contexts
vcs1-fds
vcs2
vcs2-contexts
vcs2-fds
...
$ sudo ./build/tests/gem_exec_parallel --run vcs1
IGT-Version: 1.23-g82137ba4 (x86_64) (Linux: 5.2.0-rc1+ x86_64)
(gem_exec_parallel:16219) igt_core-WARNING: Unknown subtest: vcs1

As you know this part is correct since CI mandates we list subtests not
applicable to running platform.

I guess we need to make the library function igt_skip instead of not
enumerating the impossible and missing engines.
But it doesn't work.. skips need to be in either subtests or fixtures.
Perhaps the idea of using a single context aware iterator has therefore
fail and we do need two separate ones. :( One just for subtest
enumeration which *only* uses the static list, and another for use in
tests, which skips missing/impossible engines depending on context.

Tvrtko

I'm willing to sweep this bit under the carpet so long as it isn't
flagged as a failure to Joonas.

Hmm I would have sworn we used to do that.. strange. Okay, I'll re-read
your patch. Notice that I did not know you are working on it so have
sent my own fix at similar time.

It still puzzles me at which point was I915_EXEC_BSD_RING1 not allowed
on single vcs parts. Was it just a fail in IGT?!? The first hunk in this
patch. Digging in history points to that..

I do recall making a decision to hide vcs1 if !vcs2 so that we didn't
duplicate (vcs, vcs1), and still have the plain randomly chosen vcs.
That is likely the additional source of confusion.
