IO event interrupt is a mechanism provided by RTAS 63 to return information about hardware error and non-error events 64 which may need OS attention. RTAS returns events for multiple 65 event types and scopes. Device drivers can register their handlers 66 to receive events. 67 68 This option will only enable the IO event platform code. You 69 will still need to enable or compile the actual drivers 70 that use this infrastruture to handle IO event interrupts. 71 72 Say Y if you are unsure. 73 74config LPARCFG 75 bool "LPAR Configuration Data" 76 depends on PPC_PSERIES 77 help 78 Provide system capacity information via human readable 79 <key word>=<value> pairs through a /proc/ppc64/lparcfg interface. 80 81config PPC_PSERIES_DEBUG 82 depends on PPC_PSERIES && PPC_EARLY_DEBUG 83 bool "Enable extra debug logging in platforms/pseries" 84 help 85 Say Y here if you want the pseries core to produce a bunch of 86 debug messages to the system log.

This is accomplished 110 by allocating pages of memory and put them "on hold". This only 111 makes sense for a system running in an LPAR where the unused pages 112 will be reused for other LPARs.
