18 select PPC_PCI_CHOICE if EXPERT
21 select HAVE_CONTEXT_TRACKING

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.
39 depends on PCI_MSI && PPC_PSERIES && EEH
43 tristate "pSeries energy management capabilities driver"
44 depends on PPC_PSERIES
47 Provides interface to platform energy management capabilities
48 on supported PSERIES platforms.
49 Provides: /sys/devices/system/cpu/pseries_(de)activation_hint_list
50 and /sys/devices/system/cpu/cpuN/pseries_(de)activation_hint
53 tristate "Scanlog dump interface"
54 depends on RTAS_PROC && PPC_PSERIES
57 bool "IO Event Interrupt support"
58 depends on PPC_PSERIES
61 Select this option, if you want to enable support for IO Event
62 interrupts. 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
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 infrastructure to handle IO event interrupts.
72 Say Y if you are unsure.
75 bool "LPAR Configuration Data"
76 depends on PPC_PSERIES
78 Provide system capacity information via human readable
79 <key word>=<value> pairs through a /proc/ppc64/lparcfg interface.
81 config PPC_PSERIES_DEBUG
82 depends on PPC_PSERIES && PPC_EARLY_DEBUG
83 bool "Enable extra debug logging in platforms/pseries"
85 Say Y here if you want the pseries core to produce a bunch of
86 debug messages to the system log. Select this if you are having a
87 problem with the pseries core and want to see more of what is
88 going on. This does not enable debugging in lpar.c, which must
89 be manually done due to its verbosity.
93 bool "Support for shared-memory logical partitions"
94 depends on PPC_PSERIES
98 Select this option to enable shared memory partition support.
99 With this option a system running in an LPAR can be given more
100 memory than physically available and will allow firmware to
101 balance memory across many LPARs.
104 tristate "Collaborative memory management"
105 depends on PPC_SMLPAR
108 Select this option, if you want to enable the kernel interface
109 to reduce the memory size of the system. 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. The interface allows firmware to
113 balance memory across many LPARs.
116 bool "Hypervisor supplied PMU events (24x7 & GPCI)"
118 depends on PERF_EVENTS && PPC_PSERIES
120 Enable access to hypervisor supplied counters in perf. Currently,
121 this enables code that uses the hcall GetPerfCounterInfo and 24x7
122 interfaces to retrieve counters. GPCI exists on Power 6 and later
123 systems. 24x7 is available on Power 8 systems.
128 bool "Dispatch Trace Log"
129 depends on PPC_SPLPAR && DEBUG_FS
131 SPLPAR machines can log hypervisor preempt & dispatch events to a
132 kernel buffer. Saying Y here will enable logging these events,
133 which are accessible through a debugfs file.
135 Say N if you are unsure.
