chcpu -p mode
Some options have a cpu-list argument. Use this argument to specify a comma-separated list of CPUs. The list can contain individual CPU addresses or ranges of addresses. For example, 0,5,7,9-11 makes the command applicable to the CPUs with the addresses 0, 5, 7, 9, 10, and 11.
- -c, --configure cpu-list
- Configure the specified CPUs. Configuring a CPU means that the hypervisor takes a CPU from the CPU pool and assigns it to the virtual hardware on which your kernel runs.
- -d, --disable cpu-list
- Disable the specified CPUs. Disabling a CPU means that the kernel sets it offline.
- -e, --enable cpu-list
- Enable the specified CPUs. Enabling a CPU means that the kernel sets it online. A CPU must be configured, see -c, before it can be enabled.
- -g, --deconfigure cpu-list
- Deconfigure the specified CPUs. Deconfiguring a CPU means that the hypervisor removes the CPU from the virtual hardware on which the Linux instance runs and returns it to the CPU pool. A CPU must be offline, see -d, before it can be deconfigured.
- -p, --dispatch mode
- Set the CPU dispatching mode (polarization). This option has an effect only if your hardware architecture and hypervisor support CPU polarization. Available modes are:
- The workload is spread across all available CPUs.
- The workload is concentrated on few CPUs.
- -r, --rescan
- Trigger a rescan of CPUs. After a rescan, the Linux kernel recognizes the new CPUs. Use this option on systems that do not automatically detect newly attached CPUs.
- -V, --version
- Display version information and exit.
- -h, --help
- Display help text and exit.
- partial success
