NAME
altmem — Alternative memory disk driver
SYNOPSIS
altmem* at altmemdev?
DESCRIPTION
The
altmem driver enables use of physical memory that is normally inaccessible by the machine-dependent
pmap(9) as a swap device.
When an alternative memory disk device is present, this device is generally preferred to hard disk-based swap space. See the swapctl(8) and fstab(5) man pages for instructions on how to assign priorities to swap devices.
