But the idle tasks secondary cpus are resolved into their "init" name through the COMM events. We have then such strange result in perf report (ditto with trace): 19.66% init [kernel] [k] acpi_idle_enter_c1 17.32% [idle] [kernel] [k] acpi_idle_enter_c1 It's then better to unify the swapper tasks into a single init name.
