2020-06-19gem_wsim: Snippet of a workload extracted from carchaseTvrtko Ursulin
Some frames from the middle of a demo with corresponding buffers. Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Acked-by: Chris Wilson <chris@chris-wilson.co.uk>
2020-06-19gem_wsim: Support random buffer sizesTvrtko Ursulin
See README for more details. v2: * No need to mess with flags. (Chris) Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>
2020-06-19gem_wsim: Buffer objects working sets and complex dependenciesTvrtko Ursulin
Add support for defining buffer object working sets and targetting them as data dependencies. For more information please see the README file. v2: * More robustness in parsing here and there.

2020-06-19gem_wsim: Rip out userspace balancingTvrtko Ursulin
Evaluation of userspace load balancing options was how this tool started but since we have settled on doing it in the kernel. Tomorrow we will want to update the tool for new engine interfaces and all this legacy code will just be a distraction. Rip out everything not related to explicit load balancing implemented via context engine maps and adjust the workloads to use it.

2019-05-23gem_wsim: Per context SSEU controlTvrtko Ursulin
A new workload command ('S') is added which allows per context slice (re-)configuration. v2: * Only query device SSEU on first use. (Chris) Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>
2019-05-23gem_wsim: Infinite batch supportTvrtko Ursulin
For simulating frame split workloads it is useful to express a batch which ends at the same time as the parallel submission on the respective bonded engine. For this we add support for infinite batch durations and the batch terminate command ('T'). Syntax looks like this: 1.RCS.*.0.0 T.-1 First step starts an infinite batch, and second command terminates the infinite batch with the usual relative workload step addressing. v2: (Chris) * Relax the recursive batch with 4096 nops between BB_START. * Check for at least gen8. * Simplify relocation entry building.

2019-05-23gem_wsim: Some more example workloadsTvrtko Ursulin
A few additional workloads useful for experimenting with scheduling. Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Acked-by: Chris Wilson <chris@chris-wilson.co.uk>
2019-05-23gem_wsim: Engine bond commandTvrtko Ursulin
Engine bonds are an i915 uAPI applicable to load balanced contexts with engine map. They allow expression rules of engine selection between two contexts when submissions are also tied with submit fences. Please refer to the README for a more detailed description. v2: * Use list of symbolic engine names instead of the mask.

2019-05-23gem_wsim: Engine map load balance commandTvrtko Ursulin
A new workload command for enabling a load balanced context map (aka Virtual Engine). Example usage: B.1 This turns on load balancing for context one, assuming it has already been configured with an engine map. Only DEFAULT engine specifier can be used with load balanced engine maps. v2: * Lift restriction to only use load balancer when enabled in context map.

2019-05-23gem_wsim: Engine map supportTvrtko Ursulin
Support new i915 uAPI for configuring contexts with engine maps. Please refer to the README file for more detailed explanation. v2: * Allow defining engine maps by class. Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>
2019-05-22gem_wsim: Submit fence supportTvrtko Ursulin
Add support for submit fences in a way similar to how normal input fences are handled. Eg: 1.RCS.500-1000.0.0 1.VCS1.3000.s-1.0 1.VCS2.3000.s-2.0 Submit fences are signalled when the originating request enters the submission backend.

2017-04-25benchmarks/gem_wsim: Command submission workload simulatorTvrtko 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. 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? * ... ?
