[igt-dev] [PATCH i-g-t 1/2] gem_wsim: Fix calibration for special VCS engine name

[igt-dev] [PATCH i-g-t 1/2] gem_wsim: Fix calibration for special VCS engine name

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

VCS is a special (non-physical) engine id/name which means load-balancing
in legacy workloads. As such when i915 balancing is not enabled it needs
to have a calibration as well.

[igt-dev] [PATCH i-g-t 2/2] gem_wsim: Mark contexts as non-persistent

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

We want to mark workload contexts as non-persistent if possible so that we
do not have to worry about leaving long (or infinite!) batches running
post exit.
