IO event interrupt is a mechanism provided by RTAS 66 to return information about hardware error and non-error events 67 which may need OS attention. RTAS returns events for multiple 68 event types and scopes. Device drivers can register their handlers 69 to receive events. 70 71 This option will only enable the IO event platform code. You 72 will still need to enable or compile the actual drivers 73 that use this infrastructure to handle IO event interrupts. 74 75 Say Y if you are unsure. 76 77config LPARCFG 78 bool "LPAR Configuration Data" 79 depends on PPC_PSERIES 80 help 81 Provide system capacity information via human readable 82 <key word>=<value> pairs through a /proc/ppc64/lparcfg interface. 83 84config PPC_PSERIES_DEBUG 85 depends on PPC_PSERIES && PPC_EARLY_DEBUG 86 bool "Enable extra debug logging in platforms/pseries" 87 help 88 Say Y here if you want the pseries core to produce a bunch of 89 debug messages to the system log. Select this if you are having a 90 problem with the pseries core and want to see more of what is 91 going on. This does not enable debugging in lpar.c, which must 92 be manually done due to its verbosity. 93 default y 94 95config PPC_SMLPAR 96 bool "Support for shared-memory logical partitions" 97 depends on PPC_PSERIES 98 select LPARCFG 99 default n 100 help 101 Select this option to enable shared memory partition support. 102 With this option a system running in an LPAR can be given more 103 memory than physically available and will allow firmware to 104 balance memory across many LPARs. 105 106config CMM 107 tristate "Collaborative memory management" 108 depends on PPC_SMLPAR 109 default y 110 help 111 Select this option, if you want to enable the kernel interface 112 to reduce the memory size of the system. This is accomplished 113 by allocating pages of memory and put them "on hold". This only 114 makes sense for a system running in an LPAR where the unused pages 115 will be reused for other LPARs. The interface allows firmware to 116 balance memory across many LPARs. 117 118config HV_PERF_CTRS 119 bool "Hypervisor supplied PMU events (24x7 & GPCI)" 120 default y 121 depends on PERF_EVENTS && PPC_PSERIES 122 help 123 Enable access to hypervisor supplied counters in perf. Currently, 124 this enables code that uses the hcall GetPerfCounterInfo and 24x7 125 interfaces to retrieve counters. GPCI exists on Power 6 and later 126 systems. 24x7 is available on Power 8 systems. 127 128 If unsure, select Y. 129 130config IBMVIO 131 depends on PPC_PSERIES 132 bool 133 default y 134 135config IBMEBUS 136 depends on PPC_PSERIES && !CPU_LITTLE_ENDIAN 137 bool "Support for GX bus based adapters" 138 help 139 Bus device driver for GX bus based adapters. 140
