Select this option to enable shared memory partition support.

With this option a system running in an LPAR can be given more

memory than physically available and will allow firmware to

balance memory across many LPARs.

Select this option, if you want to enable the kernel interface
|
||
|
|
to reduce the memory size of the system. This is accomplished
|
||
|
|
by allocating pages of memory and put them "on hold". This only
|
||
|
|
makes sense for a system running in an LPAR where the unused pages
|
||
|
|
will be reused for other LPARs. The interface allows firmware to
|
||
|
|
balance memory across many LPARs.

SPLPAR machines can log hypervisor preempt & dispatch events to a

kernel buffer. Saying Y here will enable logging these events,
|

which are accessible through a debugfs file.
|

|
|
Say N if you are unsure.
