Select this option if you want to use your expanded storage on S/390
|
|

|
|
or zSeries as a disk. This is useful as a _fast_ swap device if you
|
|
|
|
|
want to access more than 2G of memory when running in 31 bit mode.
|
|
|
|
|
This option is also available as a module which will be called

xpram. If unsure, say "N".

This driver provides an additional interface to the channel measurement
|
|
|
|
|
facility, which is normally accessed though sysfs, with a set of
|
|
|
|
|
ioctl functions specific to the dasd driver.
|
|

This is only needed if you want to use applications written for
|
|

linux-2.4 dasd channel measurement facility interface.
