Help text

A robust mechanism to get reliable kernel crash dump with assistance from firmware. This approach does not use kexec, instead firmware assists in booting the capture kernel while preserving memory contents. Firmware-assisted dump is meant to be a kdump replacement offering robustness and speed not possible without system firmware assistance.

If unsure, say "y". Only special kernels like petitboot may need to say "N" here.
