From: Tvrtko Ursulin
Tool which emits batch buffers to engines with configurable
sequences, durations, contexts, dependencies and userspace waits.
Unfinished but shows promise so sending out for early feedback.
v2:
* Load workload descriptors from files. (also -w)
* Help text.
* Calibration control if needed. (-t)
* NORELOC | LUT to eb flags.
* Added sample workload to wsim/workload1.
TODO list:
* Better error handling.
* Multi-context support for individual clients.
* Random/variable batch length.
* Load balancing plug-in.
* ... ?
