media-bench: Add mixed mode evaluation

2018-09-14T11:53:27+00:00

Mixed mode (-m) enables evaluation of different workload sets against one or more load balancing strategies. Contrary to the default mode which runs all selected workloads serialy, mixed mode runs a second stage where they are all run in parallel. The performance difference between the two passes is then used for the scoring metric. First metric is the normalized aggregate throughput, and second is balancer "fairness" as approximated by throughput achieved in mixed mode, relative to the best individual balancer for each workload.

media-bench: Protect against incorrect -b syntax

2018-09-14T11:53:27+00:00

-b is to pass the command argument directly to gem_wsim so must include another -b. Signed-off-by: Tvrtko Ursulin Acked-by: Chris Wilson

trace.pl: Fix frequency timeline

2018-09-14T11:48:32+00:00

Frequency timeline needs to be finished with an entry spanning to the end of known time so that the last known frequency is displayed. Signed-off-by: Tvrtko Ursulin Acked-by: Chris Wilson

trace.pl: Bring back timeline stacking

2018-08-02T10:36:03+00:00

Bring back the button which expands/stacks overlapping timeline boxes. We default to no stacking, but sometimes expanding the view can be useful, especially with deep request pipelines. Signed-off-by: Tvrtko Ursulin Reviewed-by: John Harrison

trace.pl: Fix request split mode

2018-08-02T10:26:08+00:00

Request split mode had several bugs, both in the original version and also after the recent refactorings. One big one was that it wasn't considering different submit ports as a reason to split execution, and also that it was too time based instead of looking at relevant timelines. In this refactoring we address the former by using the engine timelines introduced in the previous patch. Secondary port submissions are moved to follow the preceding submission as a first step in the correction process. In the second step, we add context timelines and use then in a similar fashion to separate start and end time of coalesced requests. For each coalesced request we know its boundaries by looking at the engine timeline (via global seqnos), and we know the previous request it should only start after, by looking at the context timeline. v2: * Remove some dead code. * Fix !port0 shifting logic. v3: * Refactor for less list walking as with incomplete handling. v4: * Database of context timelines should not contain duplicates! (Converted from array into a hash.) v5: * Avoid over-accounting runnable time for a coalesced group by recording the time first request entered the GPU and ending the execute delay at that point for the whole group. v6: * Update for engine class:instance.

trace.pl: Context save only applies to last request of a bunch

Skip accounting the context save time for anything but the last request of the coalesced bunch, and also skip drawing those boxes on the timeline. Signed-off-by: Tvrtko Ursulin Reviewed-by: John Harrison
