Modify the state of memory blocks (online or offline) in a Linux system. Typically used in virtualized environments to manage memory hotplug. More information: https://manned.org/chmem.

• Set a memory block offline:

sudo chmem {{[-b|--block]}} {{[-d|--disable]}} {{block_number}}

• Set a memory block online:

sudo chmem {{[-b|--block]}} {{[-e|--enable]}} {{block_number}}

• Set a memory range offline using hexadecimal addresses:

sudo chmem {{[-d|--disable]}} 0x{{start_address}}-0x{{end_address}}

• Set a memory range online using hexadecimal addresses:

sudo chmem {{[-e|--enable]}} 0x{{start_address}}-0x{{end_address}}

• Set memory online and assign it to a specific zone (e.g., Movable):

sudo chmem {{[-e|--enable]}} 0x{{start_address}} {{[-z|--zone]}} {{Movable}}
