ALTMEM(4) BSD Kernel Interfaces Manual ALTMEM(4)
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.
FILES
/dev/altmem?? block mode alternative memory disk devices.
/dev/raltmem?? raw mode alternative memory disk devices.
