5. set cpu mask 00 to stop profiling
The following attributes are also available:
• cpumask - profile which CPUs.
• module - show kernel module (This is only available when the kernel is module mode).
• show - show kernel profiling result.
• start - start kernel profiling data.
• stop - copy kernel profiling data.
• sysmap - show kernel sysmap.
