	  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.

config BOOTX_TEXT
	bool "Support for early boot text console"
	depends PPC_OF
	help
	  Say Y here to see progress messages from the boot firmware in text
	  mode. Requires an Open Firmware compatible video card.

config POWER4_ONLY
	bool "Optimize for POWER4"
	default n
	---help---
	  Cause the compiler to optimize for POWER4 processors. The resulting
	  binary will not work on POWER3 or RS64 processors when compiled with
	  binutils 2.15 or later.

config IOMMU_VMERGE
	bool "Enable IOMMU virtual merging (EXPERIMENTAL)"
	depends on EXPERIMENTAL
	default n
	help
	  Cause IO segments sent to a device for DMA to be merged virtually
	  by the IOMMU when they happen to have been allocated contiguously.
	  This doesn't add pressure to the IOMMU allocator. However, some
	  drivers don't support getting large merged segments coming back
	  from *_map_sg(). Say Y if you know the drivers you are using are
	  properly handling this case.

config SMP
	bool "Symmetric multi-processing support"
	---help---
	  This enables support for systems with more than one CPU. If you have
	  a system with only one CPU, say N. If you have a system with more
	  than one CPU, say Y.

	  If you say N here, the kernel will run on single and multiprocessor
	  machines, but will use only one CPU of a multiprocessor machine. If
	  you say Y here, the kernel will run on single-processor machines.
	  On a single-processor machine, the kernel will run faster if you say
	  N here.

	  If you don't know what to do here, say Y.

config NR_CPUS
	int "Maximum number of CPUs (2-128)"
	range 2 128
	depends on SMP
	default "32"

config HMT
	bool "Hardware multithreading"
	depends on SMP && PPC_PSERIES && BROKEN
	help
	  This option enables hardware multithreading on RS64 cpus.
	  pSeries systems p620 and p660 have such a cpu type.

config DISCONTIGMEM
	bool "Discontiguous Memory Support"
	depends on SMP && PPC_PSERIES

config NUMA
	bool "NUMA support"
	depends on DISCONTIGMEM

config SCHED_SMT
	bool "SMT (Hyperthreading) scheduler support"
	depends on SMP
	default off
	help
	  SMT scheduler support improves the CPU scheduler's decision making
	  when dealing with POWER5 cpus at a cost of slightly increased
	  overhead in some places. If unsure say N here.

config PREEMPT
	bool "Preemptible Kernel"
	help
	  This option reduces the latency of the kernel when reacting to
	  real-time or interactive events by allowing a low priority process to
	  be preempted even if it is in kernel mode executing a system call.

	  Say Y here if you are building a kernel for a desktop, embedded
	  or real-time system.  Say N if you are unsure.

config PREEMPT_BKL
	bool "Preempt The Big Kernel Lock"
	depends on PREEMPT
	default y
	help
	  This option reduces the latency of the kernel by making the
	  big kernel lock preemptible.

	  Say Y here if you are building a kernel for a desktop system.
	  Say N if you are unsure.

config EEH
	bool "PCI Extended Error Handling (EEH)" if EMBEDDED

	depends on RTAS_PROC && PPC_PSERIES

config LPARCFG
	tristate "LPAR Configuration Data"
	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 SECCOMP
	bool "Enable seccomp to safely compute untrusted bytecode"
	depends on PROC_FS
	default y
	help
	  This kernel feature is useful for number crunching applications
	  that may need to compute untrusted bytecode during their
	  execution. By using pipes or other transports made available to
	  the process as file descriptors supporting the read/write
	  syscalls, it's possible to isolate those applications in
	  their own address space using seccomp. Once seccomp is
	  enabled via /proc/<pid>/seccomp, it cannot be disabled
	  and the task is only allowed to execute a few safe syscalls
	  defined by each seccomp mode.

	  If unsure, say Y. Only embedded should say N here.

config ISA_DMA_API
	bool
	default y

menu "General setup"

config ISA
	bool
	help
	  Find out whether you have ISA slots on your motherboard.  ISA is the
	  name of a bus system, i.e. the way the CPU talks to the other stuff
	  inside your box.  If you have an Apple machine, say N here; if you
	  have an IBM RS/6000 or pSeries machine or a PReP machine, say Y.  If
	  you have an embedded board, consult your board documentation.

config SBUS
	bool

config MCA
	bool

config EISA
	bool

config PCI
	bool
	default y
	help
	  Find out whether your system includes a PCI bus. PCI is the name of
	  a bus system, i.e. the way the CPU talks to the other stuff inside
	  your box.  If you say Y here, the kernel will include drivers and
	  infrastructure code to support PCI bus devices.

	depends on !PPC_ISERIES
	help
	  This option adds a device-tree directory under /proc which contains
	  an image of the device tree that the kernel copies from Open
	  Firmware. If unsure, say Y here.

config CMDLINE_BOOL
	bool "Default bootloader kernel arguments"
	depends on !PPC_ISERIES

config CMDLINE
	string "Initial kernel command string"

	default "console=ttyS0,9600 console=tty0 root=/dev/sda2"
	help
	  On some platforms, there is currently no way for the boot loader to
	  pass arguments to the kernel. For these platforms, you can supply
	  some command-line options at build time by entering them here.  In
	  most cases you will need to specify the root device here.
