A few additional workloads useful for experimenting with scheduling.
Signed-off-by: Tvrtko Ursulin <tvrtko.ursu...@intel.com>
Are the extra modes & .wsim supported by scripts/media-bench.pl?
i.e. can I just run media-bench.pl and have it exercise all the new
features?
Not sure what you mean by extra modes? If all new wsim commands then no.
They are not in the default media-bench.pl set. The workloads from this
patch are not in that set so are just for reference.
That's what I meant, are the new example.wsim with explicit engine maps
and so I presume inter-mixing of load-balanced workloads with other work
included in the default set run by ./scripts/media-bench.pl
It's not in the default set but manual workloads can be given to
media-bench.pl using the -w switch. String passed there is passed onto
gem_wsim directly so one or more workloads can be manually specified.
What's the minimum amount of effort I need to exercise all the new
features of gem_wsim? :)
frame-split-60fps.wsim uses almost all new features: preemption control,
engine map, load balance, bond, submit fence and the "endless" batch.
Only missing is SSEU control for which I did not add an example workload
(there is a snippet in README though) since the access to uapi is
blocked outside the gen11 special case. To use that the i915 IS_GEN11
check in set_sseu needs to be lifted as well.
Virtual engine (gem_wsim -b i915) is supported by media-bench.pl even
with the old/default set of workloads.
The catch is old wsim workloads use VCS to mean any VCS and in those
cases -b i915 will set up the virtual engine
automatically/transparently. So those old workloads can be ran both with
userspace or i915 balancing.
And seems to still be working.
I'd hope so, I mostly do test things! :)

Tvrtko
