2 depends on PPC64 && PPC_BOOK3S
3 bool "IBM pSeries & new (POWER5-based) iSeries"
12 select PPC_RTAS_DAEMON
13 select RTAS_ERROR_LOGGING
16 select PPC_PCI_CHOICE if EXPERT
20 depends on PPC_PSERIES
21 bool "Support for shared-processor logical partitions"
24 Enabling this option will make the kernel run more efficiently
25 on logically-partitioned pSeries systems which use shared
26 processors, that is, which share physical processors between
27 two or more partitions.
30 bool "PCI Extended Error Handling (EEH)" if EXPERT
31 depends on PPC_PSERIES && PCI
36 depends on PCI_MSI && EEH
40 tristate "pSeries energy management capabilities driver"
41 depends on PPC_PSERIES
44 Provides interface to platform energy management capabilities
45 on supported PSERIES platforms.
46 Provides: /sys/devices/system/cpu/pseries_(de)activation_hint_list
47 and /sys/devices/system/cpu/cpuN/pseries_(de)activation_hint
50 tristate "Scanlog dump interface"
51 depends on RTAS_PROC && PPC_PSERIES
54 bool "IO Event Interrupt support"
55 depends on PPC_PSERIES
58 Select this option, if you want to enable support for IO Event
59 interrupts. IO event interrupt is a mechanism provided by RTAS
60 to return information about hardware error and non-error events
61 which may need OS attention. RTAS returns events for multiple
62 event types and scopes. Device drivers can register their handlers
65 This option will only enable the IO event platform code. You
66 will still need to enable or compile the actual drivers
67 that use this infrastruture to handle IO event interrupts.
69 Say Y if you are unsure.
72 bool "LPAR Configuration Data"
73 depends on PPC_PSERIES || PPC_ISERIES
75 Provide system capacity information via human readable
76 <key word>=<value> pairs through a /proc/ppc64/lparcfg interface.
78 config PPC_PSERIES_DEBUG
79 depends on PPC_PSERIES && PPC_EARLY_DEBUG
80 bool "Enable extra debug logging in platforms/pseries"
82 Say Y here if you want the pseries core to produce a bunch of
83 debug messages to the system log. Select this if you are having a
84 problem with the pseries core and want to see more of what is
85 going on. This does not enable debugging in lpar.c, which must
86 be manually done due to its verbosity.
90 bool "Support for shared-memory logical partitions"
91 depends on PPC_PSERIES
95 Select this option to enable shared memory partition support.
96 With this option a system running in an LPAR can be given more
97 memory than physically available and will allow firmware to
98 balance memory across many LPARs.
101 tristate "Collaborative memory management"
102 depends on PPC_SMLPAR
105 Select this option, if you want to enable the kernel interface
106 to reduce the memory size of the system. This is accomplished
107 by allocating pages of memory and put them "on hold". This only
108 makes sense for a system running in an LPAR where the unused pages
109 will be reused for other LPARs. The interface allows firmware to
110 balance memory across many LPARs.
113 bool "Dispatch Trace Log"
114 depends on PPC_SPLPAR && DEBUG_FS
116 SPLPAR machines can log hypervisor preempt & dispatch events to a
117 kernel buffer. Saying Y here will enable logging these events,
118 which are accessible through a debugfs file.
120 Say N if you are unsure.
