20 select HAVE_CONTEXT_TRACKING

28 bool "Support for shared-processor logical partitions"
31 Enabling this option will make the kernel run more efficiently
32 on logically-partitioned pSeries systems which use shared
33 processors, that is, which share physical processors between
34 two or more partitions.
37 bool "Dispatch Trace Log"
38 depends on PPC_SPLPAR && DEBUG_FS
40 SPLPAR machines can log hypervisor preempt & dispatch events to a
41 kernel buffer. Saying Y here will enable logging these events,
42 which are accessible through a debugfs file.
44 Say N if you are unsure.
47 tristate "pSeries energy management capabilities driver"
48 depends on PPC_PSERIES
51 Provides interface to platform energy management capabilities
52 on supported PSERIES platforms.
53 Provides: /sys/devices/system/cpu/pseries_(de)activation_hint_list
54 and /sys/devices/system/cpu/cpuN/pseries_(de)activation_hint
57 tristate "Scanlog dump interface"
58 depends on RTAS_PROC && PPC_PSERIES
61 bool "IO Event Interrupt support"
62 depends on PPC_PSERIES
65 Select this option, if you want to enable support for IO Event
66 interrupts. IO event interrupt is a mechanism provided by RTAS
67 to return information about hardware error and non-error events
68 which may need OS attention. RTAS returns events for multiple
69 event types and scopes. Device drivers can register their handlers
72 This option will only enable the IO event platform code. You
73 will still need to enable or compile the actual drivers
74 that use this infrastructure to handle IO event interrupts.
76 Say Y if you are unsure.
79 bool "LPAR Configuration Data"
80 depends on PPC_PSERIES
82 Provide system capacity information via human readable
83 <key word>=<value> pairs through a /proc/ppc64/lparcfg interface.
85 config PPC_PSERIES_DEBUG
86 depends on PPC_PSERIES && PPC_EARLY_DEBUG
87 bool "Enable extra debug logging in platforms/pseries"
89 Say Y here if you want the pseries core to produce a bunch of
90 debug messages to the system log. Select this if you are having a
91 problem with the pseries core and want to see more of what is
92 going on. This does not enable debugging in lpar.c, which must
93 be manually done due to its verbosity.
97 bool "Support for shared-memory logical partitions"
98 depends on PPC_PSERIES
102 Select this option to enable shared memory partition support.
103 With this option a system running in an LPAR can be given more
104 memory than physically available and will allow firmware to
105 balance memory across many LPARs.
108 tristate "Collaborative memory management"
109 depends on PPC_SMLPAR
112 Select this option, if you want to enable the kernel interface
113 to reduce the memory size of the system. This is accomplished
114 by allocating pages of memory and put them "on hold". This only
115 makes sense for a system running in an LPAR where the unused pages
116 will be reused for other LPARs. The interface allows firmware to
117 balance memory across many LPARs.
120 bool "Hypervisor supplied PMU events (24x7 & GPCI)"
122 depends on PERF_EVENTS && PPC_PSERIES
124 Enable access to hypervisor supplied counters in perf. Currently,
125 this enables code that uses the hcall GetPerfCounterInfo and 24x7
126 interfaces to retrieve counters. GPCI exists on Power 6 and later
127 systems. 24x7 is available on Power 8 systems.

138 bool "Support for GX bus based adapters"
140 Bus device driver for GX bus based adapters.
