Alternative memory disk driver
altmem* at altmemdev?
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.
The altmem
device driver appeared in
NetBSD 6.0.
