In linux kernel since version 4.14.326 (release Date: 2023-09-23)  
This driver provides access to virtio-mem paravirtualized memory
devices, allowing to hotplug and hotunplug memory.

This driver currently supports x86-64, arm64, riscv and s390.
Although it should compile on other architectures that implement
memory hot(un)plug, architecture-specific and/or common
code changes may be required for virtio-mem, kdump and kexec to
work as expected.

If unsure, say M.
