+config IO_EVENT_IRQ
+ bool "IO Event Interrupt support"
+ depends on PPC_PSERIES
+ default y
+ help
+ Select this option, if you want to enable support for IO Event
+ interrupts. IO event interrupt is a mechanism provided by RTAS
+ to return information about hardware error and non-error events
+ which may need OS attention. RTAS returns events for multiple
+ event types and scopes. Device drivers can register their handlers
+ to receive events.
+
+ This option will only enable the IO event platform code. You
+ will still need to enable or compile the actual drivers
+ that use this infrastruture to handle IO event interrupts.
+
+ Say Y if you are unsure.

+config PPC_PSERIES_DEBUG
+ depends on PPC_PSERIES && PPC_EARLY_DEBUG
+ bool "Enable extra debug logging in platforms/pseries"
+ help
+ Say Y here if you want the pseries core to produce a bunch of
+ debug messages to the system log. Select this if you are having a
+ problem with the pseries core and want to see more of what is
+ going on. This does not enable debugging in lpar.c, which must
+ be manually done due to its verbosity.
+ default y

+config PPC_SMLPAR
+ bool "Support for shared-memory logical partitions"
+ depends on PPC_PSERIES
+ select LPARCFG
+ default n
+ help
+ 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.
+
+config CMM
+ tristate "Collaborative memory management"
+ depends on PPC_SMLPAR
+ default y
+ help
+ 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.
+
+config DTL
+ bool "Dispatch Trace Log"
+ depends on PPC_SPLPAR && DEBUG_FS
+ help
+ 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.
