[PATCH 2/3] rteval: Add run_on_isolcpus option to measurements

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add option --measurement-run-on-isolcpus for the user to specify to
include isolcpus in the default cpulist (without --measurement-cpulist).

A default value might also be specified in rteval.conf:
[measurement]
run-on-isolcpus: true

Note that values different from true evaluate as false.
