These ones demonstrate fence usage and also mixing them with
data dependencies.

Two new workload commands are added, 'f' and 'q.<idx>' which
enable creation and signalling of non i915 fences.

Add sync fence dependency support to workload steps.
Only one sync fence dependency per step is supported at the
moment.

hd06mp2, hd12: Want many parallel clients (20+) and lets itself
be balanced.
fhd26u7, 4k12u7: Simulates either encoder or decoder with VCS1
(HEVC) dependency and some balancing VCS usage. Needs fewer
clients (3-6).
hd01, hd17i4: Mostly RCS limited targetting maximum execution
speed for a single client. Must not be hampered by incorrect
balancing decisions.

Multiple dependencies separated by forward slashes are now supported.
Some media workloads also updated to use this for better efficiency.

Workloads generated from a high level description of how
things usually work in the transcoding world.

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.
v3:
* Multiple parallel different workloads (-w -w ...).
* Multi-context workloads.
* Variable (random) batch length.
* Load balancing (round robin and queue depth estimation).
* Workloads delays and explicit sync steps.
* Workload frequency (period) control.
v4:
* Fixed queue-depth estimation by creating separate batches
per engine when qd load balancing is on.
* Dropped separate -s cmd line option. It can turn itself on
automatically when needed.
* Keep a single status page and lie about the write hazard
as suggested by Chris.
* Use batch_start_offset for controlling the batch duration.
(Chris)
* Set status page object cache level. (Chris)
* Moved workload description to a README.
* Tidied example workloads.
* Some other cleanups and refactorings.
v5:
* Master and background workloads (-W / -w).
* Single batch per step is enough even when balancing. (Chris)
* Use hars_petruska_f54_1_random IGT functions and see to zero
at start. (Chris)
* Use WC cache domain when WC mapping. (Chris)
* Keep seqnos 64-bytes apart in the status page. (Chris)
* Add workload throttling and queue-depth throttling commands.
(Chris)
v6:
* Added two more workloads.
* Merged RT balancer from Chris.
v7:
* Merged NO_RELOC patch from Chris.
* Added missing RT balancer to help text.
TODO list:
* Fence support.
* Batch buffer caching (re-use pool).
* Better error handling.
* Less 1980's workload parsing.
* More workloads.
* Threads?
* ... ?
