Also, it is possible to reproduce this in the default kernel config (no pinning is required) simply with igt/benchmarks/gem_latency -n 0 in which case the perf difference between the two setups was ~8x in my testing.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
