 31           Enabling this option will make the kernel run more efficiently
 32           on logically-partitioned pSeries systems which use shared
 33           processors, that is, which share physical processors between
 34           two or more partitions.

 40           SPLPAR machines can log hypervisor preempt & dispatch events to a
 41           kernel buffer. Saying Y here will enable logging these events,
 42           which are accessible through a debugfs file.

 69         help
 70           Select this option, if you want to enable support for IO Event
 71           interrupts. IO event interrupt is a mechanism provided by RTAS
 72           to return information about hardware error and non-error events
 73           which may need OS attention. RTAS returns events for multiple
 74           event types and scopes. Device drivers can register their handlers
 75           to receive events.
 76 
 77           This option will only enable the IO event platform code. You
 78           will still need to enable or compile the actual drivers
 79           that use this infrastructure to handle IO event interrupts.

 93         help
 94           Say Y here if you want the pseries core to produce a bunch of
 95           debug messages to the system log. Select this if you are having a
 96           problem with the pseries core and want to see more of what is
 97           going on. This does not enable debugging in lpar.c, which must
 98           be manually done due to its verbosity.

107           Select this option to enable shared memory partition support.
108           With this option a system running in an LPAR can be given more
109           memory than physically available and will allow firmware to
110           balance memory across many LPARs.

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

128        help
129           Enable access to hypervisor supplied counters in perf. Currently,
130           this enables code that uses the hcall GetPerfCounterInfo and 24x7
131           interfaces to retrieve counters. GPCI exists on Power 6 and later
132           systems. 24x7 is available on Power 8 systems.

134           If unsure, select Y.
