IO event interrupt is a mechanism provided by RTAS 62 to return information about hardware error and non-error events 63 which may need OS attention. RTAS returns events for multiple 64 event types and scopes. Device drivers can register their handlers 65 to receive events. 66 67 This option will only enable the IO event platform code. You 68 will still need to enable or compile the actual drivers 69 that use this infrastruture to handle IO event interrupts. 70 71 Say Y if you are unsure. 72 73config LPARCFG 74 bool "LPAR Configuration Data" 75 depends on PPC_PSERIES || PPC_ISERIES 76 help 77 Provide system capacity information via human readable 78 <key word>=<value> pairs through a /proc/ppc64/lparcfg interface. 79 80config PPC_PSERIES_DEBUG 81 depends on PPC_PSERIES && PPC_EARLY_DEBUG 82 bool "Enable extra debug logging in platforms/pseries" 83 help 84 Say Y here if you want the pseries core to produce a bunch of 85 debug messages to the system log.

This is accomplished 109 by allocating pages of memory and put them "on hold". This only 110 makes sense for a system running in an LPAR where the unused pages 111 will be reused for other LPARs.
