bool "Support for shared-processor logical partitions"

help
Enabling this option will make the kernel run more efficiently
on logically-partitioned pSeries systems which use shared
processors, that is, which share physical processors between
two or more partitions.

depends on PPC_PSERIES && PCI
default y if !EMBEDDED
config PSERIES_MSI

default y
help
Provides interface to platform energy management capabilities
on supported PSERIES platforms.
Provides: /sys/devices/system/cpu/pseries_(de)activation_hint_list
and /sys/devices/system/cpu/cpuN/pseries_(de)activation_hint

depends on PPC_PSERIES || PPC_ISERIES
help
Provide system capacity information via human readable
<key word>=<value> pairs through a /proc/ppc64/lparcfg interface.
config PPC_PSERIES_DEBUG
depends on PPC_PSERIES && PPC_EARLY_DEBUG
bool "Enable extra debug logging in platforms/pseries"
help
Say Y here if you want the pseries core to produce a bunch of
debug messages to the system log. Select this if you are having a
problem with the pseries core and want to see more of what is
going on. This does not enable debugging in lpar.c, which must
be manually done due to its verbosity.
default y
config PPC_SMLPAR
bool "Support for shared-memory logical partitions"
depends on PPC_PSERIES
select LPARCFG
default n
help
Select this option to enable shared memory partition support.
With this option a system running in an LPAR can be given more
memory than physically available and will allow firmware to
balance memory across many LPARs.
config CMM
tristate "Collaborative memory management"
depends on PPC_SMLPAR
default y
help
Select this option, if you want to enable the kernel interface
to reduce the memory size of the system. This is accomplished
by allocating pages of memory and put them "on hold". This only
makes sense for a system running in an LPAR where the unused pages
will be reused for other LPARs. The interface allows firmware to
balance memory across many LPARs.
config DTL
bool "Dispatch Trace Log"
depends on PPC_SPLPAR && DEBUG_FS
help
SPLPAR machines can log hypervisor preempt & dispatch events to a
kernel buffer. Saying Y here will enable logging these events,
which are accessible through a debugfs file.
Say N if you are unsure.
