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 "LPAR Configuration Data"
55 depends on PPC_PSERIES || PPC_ISERIES
57 Provide system capacity information via human readable
58 <key word>=<value> pairs through a /proc/ppc64/lparcfg interface.
60 config PPC_PSERIES_DEBUG
61 depends on PPC_PSERIES && PPC_EARLY_DEBUG
62 bool "Enable extra debug logging in platforms/pseries"
64 Say Y here if you want the pseries core to produce a bunch of
65 debug messages to the system log. Select this if you are having a
66 problem with the pseries core and want to see more of what is
67 going on. This does not enable debugging in lpar.c, which must
68 be manually done due to its verbosity.
72 bool "Support for shared-memory logical partitions"
73 depends on PPC_PSERIES
77 Select this option to enable shared memory partition support.
78 With this option a system running in an LPAR can be given more
79 memory than physically available and will allow firmware to
80 balance memory across many LPARs.
83 tristate "Collaborative memory management"
87 Select this option, if you want to enable the kernel interface
88 to reduce the memory size of the system. This is accomplished
89 by allocating pages of memory and put them "on hold". This only
90 makes sense for a system running in an LPAR where the unused pages
91 will be reused for other LPARs. The interface allows firmware to
92 balance memory across many LPARs.
95 bool "Dispatch Trace Log"
96 depends on PPC_SPLPAR && DEBUG_FS
98 SPLPAR machines can log hypervisor preempt & dispatch events to a
99 kernel buffer. Saying Y here will enable logging these events,
100 which are accessible through a debugfs file.
102 Say N if you are unsure.
