[PATCH 1/2] drm/i915/guc: Advance over port[0] if set and not preempting

[PATCH 1/2] drm/i915/guc: Advance over port[0] if set and not preempting

[Chris Wilson]

Our execlist emulation is intended to only use a maximum of 2 ports per
engine, so as to not overflow the wq. (By knowing the limits, we can
avoid having to handle the wq exhaustion.) However, upon adding
preemption, we lost the skip over the first port if set for the
non-preemption path. Restore it.

You probably want to stick with last_port, or at least Mika will want to
make it last_port again after he expands ELSP[] and propagates all the
changes.

Now it makes sense to me. You might want a stamp from Michał too.

This looks cleaner this way. We can always bring it back if it truely
helps readability. There has been too much last_port == port[1]
assumptions to tackle with.
