3 bool "IBM pSeries & new (POWER5-based) iSeries"
10 select RTAS_ERROR_LOGGING
13 select PPC_PCI_CHOICE if EXPERT
17 depends on PPC_PSERIES
18 bool "Support for shared-processor logical partitions"
21 Enabling this option will make the kernel run more efficiently
22 on logically-partitioned pSeries systems which use shared
23 processors, that is, which share physical processors between
24 two or more partitions.
27 bool "PCI Extended Error Handling (EEH)" if EXPERT
28 depends on PPC_PSERIES && PCI
33 depends on PCI_MSI && EEH
37 tristate "pSeries energy management capabilities driver"
38 depends on PPC_PSERIES
41 Provides interface to platform energy management capabilities
42 on supported PSERIES platforms.
43 Provides: /sys/devices/system/cpu/pseries_(de)activation_hint_list
44 and /sys/devices/system/cpu/cpuN/pseries_(de)activation_hint
47 tristate "Scanlog dump interface"
48 depends on RTAS_PROC && PPC_PSERIES
51 bool "LPAR Configuration Data"
52 depends on PPC_PSERIES || PPC_ISERIES
54 Provide system capacity information via human readable
55 <key word>=<value> pairs through a /proc/ppc64/lparcfg interface.
57 config PPC_PSERIES_DEBUG
58 depends on PPC_PSERIES && PPC_EARLY_DEBUG
59 bool "Enable extra debug logging in platforms/pseries"
61 Say Y here if you want the pseries core to produce a bunch of
62 debug messages to the system log. Select this if you are having a
63 problem with the pseries core and want to see more of what is
64 going on. This does not enable debugging in lpar.c, which must
65 be manually done due to its verbosity.
69 bool "Support for shared-memory logical partitions"
70 depends on PPC_PSERIES
74 Select this option to enable shared memory partition support.
75 With this option a system running in an LPAR can be given more
76 memory than physically available and will allow firmware to
77 balance memory across many LPARs.
80 tristate "Collaborative memory management"
84 Select this option, if you want to enable the kernel interface
85 to reduce the memory size of the system. This is accomplished
86 by allocating pages of memory and put them "on hold". This only
87 makes sense for a system running in an LPAR where the unused pages
88 will be reused for other LPARs. The interface allows firmware to
89 balance memory across many LPARs.
92 bool "Dispatch Trace Log"
93 depends on PPC_SPLPAR && DEBUG_FS
95 SPLPAR machines can log hypervisor preempt & dispatch events to a
96 kernel buffer. Saying Y here will enable logging these events,
97 which are accessible through a debugfs file.
99 Say N if you are unsure.
