18 select PPC_PCI_CHOICE if EXPERT
24 depends on PPC_PSERIES
25 bool "Support for shared-processor logical partitions"
28 Enabling this option will make the kernel run more efficiently
29 on logically-partitioned pSeries systems which use shared
30 processors, that is, which share physical processors between
31 two or more partitions.
35 depends on PPC_PSERIES && PCI
40 depends on PCI_MSI && EEH
44 tristate "pSeries energy management capabilities driver"
45 depends on PPC_PSERIES
48 Provides interface to platform energy management capabilities
49 on supported PSERIES platforms.
50 Provides: /sys/devices/system/cpu/pseries_(de)activation_hint_list
51 and /sys/devices/system/cpu/cpuN/pseries_(de)activation_hint
54 tristate "Scanlog dump interface"
55 depends on RTAS_PROC && PPC_PSERIES
58 bool "IO Event Interrupt support"
59 depends on PPC_PSERIES
62 Select this option, if you want to enable support for IO Event
63 interrupts. IO event interrupt is a mechanism provided by RTAS
64 to return information about hardware error and non-error events
65 which may need OS attention. RTAS returns events for multiple
66 event types and scopes. Device drivers can register their handlers
69 This option will only enable the IO event platform code. You
70 will still need to enable or compile the actual drivers
71 that use this infrastructure to handle IO event interrupts.
73 Say Y if you are unsure.
76 bool "LPAR Configuration Data"
77 depends on PPC_PSERIES
79 Provide system capacity information via human readable
80 <key word>=<value> pairs through a /proc/ppc64/lparcfg interface.
82 config PPC_PSERIES_DEBUG
83 depends on PPC_PSERIES && PPC_EARLY_DEBUG
84 bool "Enable extra debug logging in platforms/pseries"
86 Say Y here if you want the pseries core to produce a bunch of
87 debug messages to the system log. Select this if you are having a
88 problem with the pseries core and want to see more of what is
89 going on. This does not enable debugging in lpar.c, which must
90 be manually done due to its verbosity.
94 bool "Support for shared-memory logical partitions"
95 depends on PPC_PSERIES
99 Select this option to enable shared memory partition support.
100 With this option a system running in an LPAR can be given more
101 memory than physically available and will allow firmware to
102 balance memory across many LPARs.
105 tristate "Collaborative memory management"
106 depends on PPC_SMLPAR
109 Select this option, if you want to enable the kernel interface
110 to reduce the memory size of the system. This is accomplished
111 by allocating pages of memory and put them "on hold". This only
112 makes sense for a system running in an LPAR where the unused pages
113 will be reused for other LPARs. The interface allows firmware to
114 balance memory across many LPARs.
117 bool "Dispatch Trace Log"
118 depends on PPC_SPLPAR && DEBUG_FS
120 SPLPAR machines can log hypervisor preempt & dispatch events to a
121 kernel buffer. Saying Y here will enable logging these events,
122 which are accessible through a debugfs file.
124 Say N if you are unsure.
127 bool "Cpuidle driver for pSeries platforms"
129 depends on PPC_PSERIES
132 Select this option to enable processor idle state management
133 through cpuidle subsystem.
