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