      benchmarks/gem_wsim: Command submission workload simulator · 054eb1ab
      Tvrtko Ursulin authored 
      
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?
 * ... ?

      tests/feat_profile.json: legacy features list for piglit summary feature · 91a137ac
      Jari Tahvanainen authored and Petri Latvala's avatar Petri Latvala committed 
      
Daniel has posted empty feat_profile.json as template to be used.
This is my understanding about the features and what tests are covering those.

Usage: piglit summary feature json-filename output-directory results-directory
