From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx> Another WIP posting with some interopability improvements this time. Example usage: root@scnuc:~/intel-gpu-tools# benchmarks/gem_wsim Calibrating nop delay with 1% tolerance... Nop calibration for 1000us delay is 438660. root@scnuc:~/intel-gpu-tools# scripts/trace.pl --trace benchmarks/gem_wsim -n 438660 -r 600 -w benchmarks/wsim/workload1 -c 2 -x Using 438660 nop calibration for 1000us delay. 2 clients. Swapping VCS rings between clients. 0: 10.222053s elapsed (58.696622 workloads/s) 1: 10.225807s elapsed (58.675078 workloads/s) 10.226307s elapsed (117.344411 workloads/s) [ perf record: Woken up 16 times to write data ] [ perf record: Captured and wrote 3.929 MB perf.data (44688 samples) ] root@scnuc:~/intel-gpu-tools# perf script | scripts/trace.pl -i 1 -i 4 Ring0: 4832 batches, 4329.07 (4348.11) avg batch us, 0.15% idle, 138.73% busy, 23.88% runnable, 79.66% queued, 0.01% wait) Ring2: 1808 batches, 1715.68 (1719.99) avg batch us, 69.68% idle, 30.38% busy, 0.12% runnable, 112.04% queued, 99.32% wait) Ring3: 1810 batches, 1727.59 (1739.31) avg batch us, 69.28% idle, 30.75% busy, 0.11% runnable, 105.37% queued, 99.46% wait) Most interesting metric here is the engine idle time which will come into play as I start adding the load balancing options to gem_wsim. Secondary mode here would be: root@scnuc:~/intel-gpu-tools# perf script | scripts/trace.pl -i 1 -i 4 --html >graph.html This would enable a timeline of GPU request execution to be viewed with a little bit of local setup as described in the trace.pl help text.
