15 select PPC_RTAS_DAEMON
16 select RTAS_ERROR_LOGGING
20 select HOTPLUG_CPU if SMP
26 depends on PPC_PSERIES
27 bool "Support for shared-processor logical partitions"
30 Enabling this option will make the kernel run more efficiently
31 on logically-partitioned pSeries systems which use shared
32 processors, that is, which share physical processors between
33 two or more partitions.
36 bool "Dispatch Trace Log"
37 depends on PPC_SPLPAR && DEBUG_FS
39 SPLPAR machines can log hypervisor preempt & dispatch events to a
40 kernel buffer. Saying Y here will enable logging these events,
41 which are accessible through a debugfs file.
43 Say N if you are unsure.
46 tristate "pSeries energy management capabilities driver"
47 depends on PPC_PSERIES
50 Provides interface to platform energy management capabilities
51 on supported PSERIES platforms.
52 Provides: /sys/devices/system/cpu/pseries_(de)activation_hint_list
53 and /sys/devices/system/cpu/cpuN/pseries_(de)activation_hint
56 tristate "Scanlog dump interface"
57 depends on RTAS_PROC && PPC_PSERIES
60 bool "IO Event Interrupt support"
61 depends on PPC_PSERIES
64 Select this option, if you want to enable support for IO Event
65 interrupts. 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
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.
75 Say Y if you are unsure.
78 bool "LPAR Configuration Data"
79 depends on PPC_PSERIES
81 Provide system capacity information via human readable
82 <key word>=<value> pairs through a /proc/ppc64/lparcfg interface.
84 config PPC_PSERIES_DEBUG
85 depends on PPC_PSERIES && PPC_EARLY_DEBUG
86 bool "Enable extra debug logging in platforms/pseries"
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.
96 bool "Support for shared-memory logical partitions"
97 depends on PPC_PSERIES
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.
107 tristate "Collaborative memory management"
108 depends on PPC_SMLPAR
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.
119 bool "Hypervisor supplied PMU events (24x7 & GPCI)"
121 depends on PERF_EVENTS && PPC_PSERIES
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.
131 depends on PPC_PSERIES
136 depends on PPC_PSERIES && !CPU_LITTLE_ENDIAN
137 bool "Support for GX bus based adapters"
139 Bus device driver for GX bus based adapters.
