Provides: /sys/devices/system/cpu/pseries_(de)activation_hint_list and /sys/devices/system/cpu/cpuN/pseries_(de)activation_hint config SCANLOG tristate "Scanlog dump interface" depends on RTAS_PROC && PPC_PSERIES config IO_EVENT_IRQ bool "IO Event Interrupt support" depends on PPC_PSERIES default y help Select this option, if you want to enable support for IO Event interrupts. IO event interrupt is a mechanism provided by RTAS to return information about hardware error and non-error events which may need OS attention. RTAS returns events for multiple event types and scopes. Device drivers can register their handlers to receive events. This option will only enable the IO event platform code. You will still need to enable or compile the actual drivers that use this infrastructure to handle IO event interrupts. Say Y if you are unsure. config LPARCFG bool "LPAR Configuration Data" depends on PPC_PSERIES 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. config PSERIES_IDLE bool "Cpuidle driver for pSeries platforms" depends on CPU_IDLE depends on PPC_PSERIES default y help Select this option to enable processor idle state management through cpuidle subsystem.
