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