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 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 PPC_PSERIES default y if !EMBEDDED # # Use the generic interrupt handling code in kernel/irq/: # config GENERIC_HARDIRQS bool default y config MSCHUNKS bool depends on PPC_ISERIES default y config PPC_RTAS bool "Proc interface to RTAS" depends on PPC_PSERIES config RTAS_FLASH tristate "Firmware flash interface" depends on PPC_RTAS config SCANLOG tristate "Scanlog dump interface" depends on PPC_RTAS 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. endmenu 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. config PCI_DOMAINS bool default PCI source "fs/Kconfig.binfmt" source "drivers/pci/Kconfig" config HOTPLUG_CPU bool "Support for hot-pluggable CPUs" depends on SMP && EXPERIMENTAL && PPC_PSERIES select HOTPLUG ---help--- Say Y here to be able to turn CPUs off and on.

If unsure, say Y here. config CMDLINE_BOOL bool "Default bootloader kernel arguments" depends on !PPC_ISERIES config CMDLINE string "Initial kernel command string" depends on CMDLINE_BOOL 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.
