2018-07-19trace.pl: Basic preemption supportTvrtko Ursulin
Just forget about earlier request_in events. Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: John Harrison <John.C.Harrison@Intel.com>
2018-07-19trace.pl: Fix incomplete request handlingTvrtko Ursulin
Incomplete requests (no notify, no context complete) have to be corrected by looking at the engine timeline, and not the sorted-by-start-time view as was previously used. Per-engine timelines are generated on demand and cached for later use. v2: Find end of current context on the engine timeline instead of just using the next request for adjusting the incomplete start time. v3: Improve scaling with large datasets by only walking each engine timeline once and some caching. (John Harrison) v4: * Fix logic fail from v3. * Refactor the code a bit to separate the stages better. * Do not account batches with unknown duration in avg stats. * Handle two user interrupts with the same seqno. * Handle user interrupt arriving after request_out. v5: * Update for class:instance.

2018-07-19trace.pl: Improve readability of graphical timeline representationTvrtko Ursulin
We add stripes for different stages of request execution so it is easier to follow one context in the multi-colour mode. Vertical stripe pattern indicates pipeline "blockages" - requests waiting for dependencies before they are runnable. Diagonal stripes indicate runnable requests waiting for GPU time. Horizontal strips are requests executing on the GPU. Also use this new multi-coloured mode from media-bench.pl. v2: John Harrison: * Mention media-bench.pl in the commit. * Fix HTML for single colour mode. v3: * Rebase. * Apply stripes to legacy colouring as well. v4: John Harrison: * Use per context colours for ctxsave and incomplete boxes. * Clearer timeline legend.

2018-07-18igt: Force eviction of test bo directlyChris Wilson
Currently we indirectly try to evict the test buffers by mmaping enough bo that should fill the aperture. However, this assumes that the kernel is trying to fill the aperture and does not use random replacement (which it does) or use small partials to avoid mmaping the whole object (which it does). Rather than assume, use the debugfs interface to force the eviction of the bound objects.

2018-07-06igt/gem_sync: Alternate stress for nop+syncChris Wilson
Apply a different sort of stress by timing how long it takes to sync a second nop batch in the pipeline. We first start a spinner on the engine, then when we know the GPU is active, we submit the second nop; start timing as we then release the spinner and wait for the nop to complete. As with every other gem_sync test, it serves two roles. The first is that it checks that we do not miss a wakeup under common stressful conditions (the more conditions we check, the happier we will be that they do not occur in practice). And the second role it fulfils, is that it provides a very crude estimate for how long it takes for a nop to execute from a running start (we already have a complimentary estimate for an idle start).
