chcpu

CHCPU(8)						       System Administration							  CHCPU(8)

NAME

       chcpu - configure CPUs

SYNOPSIS

       chcpu -c|-d|-e|-g cpu-list
       chcpu -p mode
       chcpu -r|-h|-V

DESCRIPTION

       chcpu  can  modify  the state of CPUs.  It can enable or disable CPUs, scan for new CPUs, change the CPU dispatching mode of the underlying
       hypervisor, and request CPUs from the hypervisor (configure) or return CPUs to the hypervisor (deconfigure).

       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.

OPTIONS

       -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  vir-
	      tual 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:

		     horizontal  The workload is spread across all available CPUs.
		     vertical	 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  auto-
	      matically detect newly attached CPUs.

       -V, --version
	      Display version information and exit.

       -h, --help
	      Display help text and exit.

RETURN CODES

       chcpu has the following return codes:

       0      success

       1      failure

       64     partial success
