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.
37 depends on PCI_MSI && PPC_PSERIES && EEH
41 tristate "pSeries energy management capabilities driver"
42 depends on PPC_PSERIES
45 Provides interface to platform energy management capabilities
46 on supported PSERIES platforms.
47 Provides: /sys/devices/system/cpu/pseries_(de)activation_hint_list
48 and /sys/devices/system/cpu/cpuN/pseries_(de)activation_hint
51 tristate "Scanlog dump interface"
52 depends on RTAS_PROC && PPC_PSERIES
55 bool "IO Event Interrupt support"
56 depends on PPC_PSERIES
59 Select this option, if you want to enable support for IO Event
60 interrupts. IO event interrupt is a mechanism provided by RTAS
61 to return information about hardware error and non-error events
62 which may need OS attention. RTAS returns events for multiple
63 event types and scopes. Device drivers can register their handlers
66 This option will only enable the IO event platform code. You
67 will still need to enable or compile the actual drivers
68 that use this infrastructure to handle IO event interrupts.
70 Say Y if you are unsure.
73 bool "LPAR Configuration Data"
74 depends on PPC_PSERIES
76 Provide system capacity information via human readable
77 <key word>=<value> pairs through a /proc/ppc64/lparcfg interface.
79 config PPC_PSERIES_DEBUG
80 depends on PPC_PSERIES && PPC_EARLY_DEBUG
81 bool "Enable extra debug logging in platforms/pseries"
83 Say Y here if you want the pseries core to produce a bunch of
84 debug messages to the system log. Select this if you are having a
85 problem with the pseries core and want to see more of what is
86 going on. This does not enable debugging in lpar.c, which must
87 be manually done due to its verbosity.
91 bool "Support for shared-memory logical partitions"
92 depends on PPC_PSERIES
96 Select this option to enable shared memory partition support.
97 With this option a system running in an LPAR can be given more
98 memory than physically available and will allow firmware to
99 balance memory across many LPARs.
102 tristate "Collaborative memory management"
103 depends on PPC_SMLPAR
106 Select this option, if you want to enable the kernel interface
107 to reduce the memory size of the system. This is accomplished
108 by allocating pages of memory and put them "on hold". This only
109 makes sense for a system running in an LPAR where the unused pages
110 will be reused for other LPARs. The interface allows firmware to
111 balance memory across many LPARs.
114 bool "Dispatch Trace Log"
115 depends on PPC_SPLPAR && DEBUG_FS
117 SPLPAR machines can log hypervisor preempt & dispatch events to a
118 kernel buffer. Saying Y here will enable logging these events,
119 which are accessible through a debugfs file.
121 Say N if you are unsure.
