This series of patches is based on series isolation: Exclude dynamically isolated CPUs from housekeeping masks: https://lore.kernel.org/lkml/20240821142312.236970-1-longman@xxxxxxxxxx/ Its purpose is to exclude dynamically isolated CPUs from some housekeeping masks so that subsystems that check the housekeeping masks at run time will not use those isolated CPUs. However, some of subsystems can use obsolete housekeeping CPU masks. Therefore, to prevent the use of these isolated CPUs, it is necessary to explicitly propagate changes of the housekeeping masks to all subsystems depending on the mask. Signed-off-by: Costa Shulyupin <costa.shul@xxxxxxxxxx> --- v4: - Use CPU hotplug as recommended by Thomas Gleixner. v3: - Address the comments by Thomas Gleixner. v2: - Focus in this patch series on managed interrupts only. Costa Shulyupin (4): cgroup/cpuset: Add HK_TYPE_MANAGED_IRQ to HOUSEKEEPING_FLAGS genirq/cpuhotplug: Dynamically isolate CPUs from managed interrupts cgroup/cpuset: Restart CPUs whose isolated_cpus bits have changed DO NOT MERGE: Test CPU isolation from managed interrupts MAINTAINERS | 2 + kernel/cgroup/cpuset.c | 36 +++++++++++ kernel/irq/cpuhotplug.c | 3 + tests/managed_irq.sh | 135 ++++++++++++++++++++++++++++++++++++++++ 4 files changed, 176 insertions(+) create mode 100755 tests/managed_irq.sh -- 2.47.0
