Helper scripts to check and set CPU isolation and execution of application in isolated CPU(s) Files: isolate-cpu.sh isolates desired CPUs isolate-task.sh uses isolate-cpu.sh to isolate CPUs before running the desired task. It also provides the possibility to trace kernel disturbance on the isolated CPUs. isolate-cpu.sh checks the kernel configuration and the kernel cmdline to determine if one or several CPUs are isolated, i.e. it checks for; CONFIG_NO_HZ_FULL_ALL=y", and CONFIG_RCU_NOCB_CPU_ALL=y" in the kernel config and rcu_nocbs,nohz_full in the kernel cmdline. If the desired CPU(s) are not inte the above configuration, it warns but continues to isolate the CPU(s) as much as possibe. The isolation is accomplished by - Redirecting all IRQ's away from desired isolated cores - Using cset (cpuset) to move all running processes and kernel threads away from desired isolated cores isolate-task.sh uses isolate-cpu.sh to isolate desired CPU(s). In addition it starts the supplied application on isolated CPU(s) and optionally traces the isolated CPU(s) for kernel interaction.
