This badly named config option is actually # max order + 1 config FORCE_MAX_ZONEORDER int depends on PPC64 default "9" if PPC_64K_PAGES default "13" config HUGETLB_PAGE_SIZE_VARIABLE bool depends on HUGETLB_PAGE default y config MATH_EMULATION bool "Math emulation" depends on 4xx || 8xx || E200 || PPC_MPC832x || E500 ---help--- Some PowerPC chips designed for embedded applications do not have a floating-point unit and therefore do not implement the floating-point instructions in the PowerPC instruction set. If you say Y here, the kernel will include code to emulate a floating-point unit, which will allow programs that use floating-point instructions to run. config 8XX_MINIMAL_FPEMU bool "Minimal math emulation for 8xx" depends on 8xx && !MATH_EMULATION help Older arch/ppc kernels still emulated a few floating point instructions such as load and store, even when full math emulation is disabled. Say "Y" here if you want to preserve this behavior. It is recommended that you build a soft-float userspace instead. config IOMMU_VMERGE bool "Enable IOMMU virtual merging" depends on PPC64 default y 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(). Most drivers don't have this problem; it is safe to say Y here. config HOTPLUG_CPU bool "Support for enabling/disabling CPUs" depends on SMP && HOTPLUG && EXPERIMENTAL && (PPC_PSERIES || PPC_PMAC) ---help--- Say Y here to be able to disable and re-enable individual CPUs at runtime on SMP machines. Say N if you are unsure. config ARCH_ENABLE_MEMORY_HOTPLUG def_bool y config KEXEC bool "kexec system call (EXPERIMENTAL)" depends on (PPC_PRPMC2800 || PPC_MULTIPLATFORM) && EXPERIMENTAL help kexec is a system call that implements the ability to shutdown your current kernel, and to start another kernel. It is like a reboot but it is independent of the system firmware. And like a reboot you can start any kernel with it, not just Linux. The name comes from the similarity to the exec system call. It is an ongoing process to be certain the hardware in a machine is properly shutdown, so do not be surprised if this code does not initially work for you. It may help to enable device hotplugging support. As of this writing the exact hardware interface is strongly in flux, so no good recommendation can be made. config CRASH_DUMP bool "Build a kdump crash kernel (EXPERIMENTAL)" depends on PPC_MULTIPLATFORM && PPC64 && EXPERIMENTAL help Build a kernel suitable for use as a kdump capture kernel. The kernel will be linked at a different address than normal, and so can only be used for Kdump. Don't change this unless you know what you are doing. config PPCBUG_NVRAM bool "Enable reading PPCBUG NVRAM during boot" if PPLUS || LOPEC default y if PPC_PREP config IRQ_ALL_CPUS bool "Distribute interrupts on all CPUs by default" depends on SMP && !MV64360 help This option gives the kernel permission to distribute IRQs across multiple CPUs. Saying N here will route all IRQs to the first CPU. Generally saying Y is safe, although some problems have been reported with SMP Power Macintoshes with this option enabled. config NUMA bool "NUMA support" depends on PPC64 default y if SMP && PPC_PSERIES config NODES_SHIFT int default "4" depends on NEED_MULTIPLE_NODES config ARCH_SELECT_MEMORY_MODEL def_bool y depends on PPC64 config ARCH_FLATMEM_ENABLE def_bool y depends on (PPC64 && !NUMA) || PPC32 config ARCH_SPARSEMEM_ENABLE def_bool y depends on PPC64 select SPARSEMEM_VMEMMAP_ENABLE config ARCH_SPARSEMEM_DEFAULT def_bool y depends on (SMP && PPC_PSERIES) || PPC_PS3 config ARCH_POPULATES_NODE_MAP def_bool y source "mm/Kconfig" config ARCH_MEMORY_PROBE def_bool y depends on MEMORY_HOTPLUG # Some NUMA nodes have memory ranges that span # other nodes. Even though a pfn is valid and # between a node's start and end pfns, it may not # reside on that node. See memmap_init_zone() # for details. config NODES_SPAN_OTHER_NODES def_bool y depends on NEED_MULTIPLE_NODES config PPC_HAS_HASH_64K bool depends on PPC64 default n config PPC_64K_PAGES bool "64k page size" depends on PPC64 select PPC_HAS_HASH_64K help This option changes the kernel logical page size to 64k. On machines without processor support for 64k pages, the kernel will simulate them by loading each individual 4k page on demand transparently, while on hardware with such support, it will be used to map normal application pages. config SCHED_SMT bool "SMT (Hyperthreading) scheduler support" depends on PPC64 && SMP 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 PROC_DEVICETREE bool "Support for device tree in /proc" depends on PROC_FS 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 or other boot firmware. If unsure, say Y here. config CMDLINE_BOOL bool "Default bootloader kernel arguments" 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. In most cases you will need to specify the root device here. if !44x || BROKEN source kernel/power/Kconfig endif 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 WANT_DEVICE_TREE bool default n config DEVICE_TREE string "Static device tree source file" depends on WANT_DEVICE_TREE help This specifies the device tree source (.dts) file to be compiled and included when building the bootwrapper. If a relative filename is given, then it will be relative to arch/powerpc/boot/dts. If you are not using the bootwrapper, or do not need to build a dts into the bootwrapper, this field is ignored. For example, this is required when building a cuImage target for an older U-Boot, which cannot pass a device tree itself. Such a kernel will not work with a newer U-Boot that tries to pass a device tree (unless you tell it not to). If your U-Boot does not mention a device tree in "help bootm", then use the cuImage target and specify a device tree here. Otherwise, use the uImage target and leave this field blank. endmenu config ISA_DMA_API bool default y menu "Bus options" config ISA bool "Support for ISA-bus hardware" depends on PPC_PREP || PPC_CHRP select PPC_I8259 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 ZONE_DMA bool default y config GENERIC_ISA_DMA bool depends on PPC64 || POWER4 || 6xx && !CPM2 default y config PPC_INDIRECT_PCI bool depends on PCI default y if 40x || 44x default n config EISA bool config SBUS bool config FSL_SOC bool config FSL_PCI bool select PPC_INDIRECT_PCI # Yes MCA RS/6000s exist but Linux-PPC does not currently support any config MCA bool config PCI bool "PCI support" if 40x || CPM2 || PPC_83xx || PPC_85xx || PPC_86xx \ || PPC_MPC52xx || (EMBEDDED && (PPC_PSERIES || PPC_ISERIES)) \ || PPC_PS3 default y if !40x && !CPM2 && !8xx && !PPC_83xx \ && !PPC_85xx && !PPC_86xx && !GAMECUBE default PCI_PERMEDIA if !4xx && !CPM2 && !8xx default PCI_QSPAN if !4xx && !CPM2 && 8xx select ARCH_SUPPORTS_MSI 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 def_bool PCI config PCI_SYSCALL def_bool PCI config PCI_QSPAN bool "QSpan PCI" depends on !4xx && !CPM2 && 8xx select PPC_I8259 help Say Y here if you have a system based on a Motorola 8xx-series embedded processor with a QSPAN PCI interface, otherwise say N. config PCI_8260 bool depends on PCI && 8260 select PPC_INDIRECT_PCI default y config 8260_PCI9 bool "Enable workaround for MPC826x erratum PCI 9" depends on PCI_8260 && !8272 default y choice prompt "IDMA channel for PCI 9 workaround" depends on 8260_PCI9 config 8260_PCI9_IDMA1 bool "IDMA1" config 8260_PCI9_IDMA2 bool "IDMA2" config 8260_PCI9_IDMA3 bool "IDMA3" config 8260_PCI9_IDMA4 bool "IDMA4" endchoice source "drivers/pci/pcie/Kconfig" source "drivers/pci/Kconfig" source "drivers/pcmcia/Kconfig" source "drivers/pci/hotplug/Kconfig" endmenu menu "Advanced setup" depends on PPC32 config ADVANCED_OPTIONS bool "Prompt for advanced kernel configuration options" help This option will enable prompting for a variety of advanced kernel configuration options. These options can cause the kernel to not work if they are set incorrectly, but can be used to optimize certain aspects of kernel memory management. Unless you know what you are doing, say N here. comment "Default settings for advanced configuration options are used" depends on !ADVANCED_OPTIONS config HIGHMEM_START_BOOL bool "Set high memory pool address" depends on ADVANCED_OPTIONS && HIGHMEM help This option allows you to set the base address of the kernel virtual area used to map high memory pages. This can be useful in optimizing the layout of kernel virtual memory. Say N here unless you know what you are doing. config HIGHMEM_START hex "Virtual start address of high memory pool" if HIGHMEM_START_BOOL default "0xfe000000" config LOWMEM_SIZE_BOOL bool "Set maximum low memory" depends on ADVANCED_OPTIONS help This option allows you to set the maximum amount of memory which will be used as "low memory", that is, memory which the kernel can access directly, without having to set up a kernel virtual mapping. This can be useful in optimizing the layout of kernel virtual memory. Say N here unless you know what you are doing. config LOWMEM_SIZE hex "Maximum low memory size (in bytes)" if LOWMEM_SIZE_BOOL default "0x30000000" config KERNEL_START_BOOL bool "Set custom kernel base address" depends on ADVANCED_OPTIONS help This option allows you to set the kernel virtual address at which the kernel will map low memory (the kernel image will be linked at this address). This can be useful in optimizing the virtual memory layout of the system.

Update of /cvsroot/gc-linux/linux/arch/powerpc/platforms In directory sc8-pr-cvs2.sourceforge.net:/tmp/cvs-serv7117/arch/powerpc/platforms Added Files: Kconfig.cputype Log Message: Added powerpc arch. Tweaked some driver for wii compatibility. --- NEW FILE: Kconfig.cputype --- config PPC64 bool "64-bit kernel" default n help This option selects whether a 32-bit or a 64-bit kernel will be built. menu "Processor support" choice prompt "Processor Type" depends on PPC32 default 6xx help There are five families of 32 bit PowerPC chips supported. The most common ones are the desktop and server CPUs (601, 603, 604, 740, 750, 74xx) CPUs from Freescale and IBM, with their embedded 52xx/82xx/83xx/86xx counterparts. The other embeeded parts, namely 4xx, 8xx, e200 (55xx) and e500 (85xx) each form a family of their own that is not compatible with the others. If unsure, select 52xx/6xx/7xx/74xx/82xx/83xx/86xx. config 6xx bool "52xx/6xx/7xx/74xx/82xx/83xx/86xx" select PPC_FPU config PPC_85xx bool "Freescale 85xx" select E500 select FSL_SOC select 85xx select WANT_DEVICE_TREE config PPC_8xx bool "Freescale 8xx" select FSL_SOC select 8xx select WANT_DEVICE_TREE select PPC_LIB_RHEAP config 40x bool "AMCC 40x" select PPC_DCR_NATIVE select WANT_DEVICE_TREE config 44x bool "AMCC 44x" select PPC_DCR_NATIVE select WANT_DEVICE_TREE select PPC_UDBG_16550 config E200 bool "Freescale e200" endchoice config POWER4_ONLY bool "Optimize for POWER4" depends on PPC64 default n ---help--- Cause the compiler to optimize for POWER4/POWER5/PPC970 processors. The resulting binary will not work on POWER3 or RS64 processors when compiled with binutils 2.15 or later. config POWER3 bool depends on PPC64 default y if !POWER4_ONLY config POWER4 depends on PPC64 def_bool y config TUNE_CELL bool "Optimize for Cell Broadband Engine" depends on PPC64 help Cause the compiler to optimize for the PPE of the Cell Broadband Engine. This will make the code run considerably faster on Cell but somewhat slower on other machines. This option only changes the scheduling of instructions, not the selection of instructions itself, so the resulting kernel will keep running on all other machines. When building a kernel that is supposed to run only on Cell, you should also select the POWER4_ONLY option. config 6xx bool # this is temp to handle compat with arch=ppc config 8xx bool # this is temp to handle compat with arch=ppc config 83xx bool # this is temp to handle compat with arch=ppc config 85xx bool config E500 bool config PPC_FPU bool default y if PPC64 config 4xx bool depends on 40x || 44x default y config BOOKE bool depends on E200 || E500 || 44x default y config FSL_BOOKE bool depends on E200 || E500 default y config PTE_64BIT bool depends on 44x || E500 default y if 44x default y if E500 && PHYS_64BIT config PHYS_64BIT bool 'Large physical address support' if E500 depends on 44x || E500 select RESOURCES_64BIT default y if 44x ---help--- This option enables kernel support for larger than 32-bit physical addresses. This features is not be available on all e500 cores. If in doubt, say N here. config ALTIVEC bool "AltiVec Support" depends on CLASSIC32 || POWER4 ---help--- This option enables kernel support for the Altivec extensions to the PowerPC processor. The kernel currently supports saving and restoring altivec registers, and turning on the 'altivec enable' bit so user processes can execute altivec instructions. This option is only usefully if you have a processor that supports altivec (G4, otherwise known as 74xx series), but does not have any affect on a non-altivec cpu (it does, however add code to the kernel). If in doubt, say Y here. config SPE bool "SPE Support" depends on E200 || E500 default y ---help--- This option enables kernel support for the Signal Processing Extensions (SPE) to the PowerPC processor. The kernel currently supports saving and restoring SPE registers, and turning on the 'spe enable' bit so user processes can execute SPE instructions. This option is only useful if you have a processor that supports SPE (e500, otherwise known as 85xx series), but does not have any effect on a non-spe cpu (it does, however add code to the kernel). If in doubt, say Y here. config PPC_STD_MMU bool depends on 6xx || POWER3 || POWER4 || PPC64 default y config PPC_STD_MMU_32 def_bool y depends on PPC_STD_MMU && PPC32 config PPC_MM_SLICES bool default y if HUGETLB_PAGE default n config VIRT_CPU_ACCOUNTING bool "Deterministic task and CPU time accounting" depends on PPC64 default y help Select this option to enable more accurate task and CPU time accounting. This is done by reading a CPU counter on each kernel entry and exit and on transitions within the kernel between system, softirq and hardirq state, so there is a small performance impact. This also enables accounting of stolen time on logically-partitioned systems running on IBM POWER5-based machines. If in doubt, say Y here. config SMP depends on PPC_STD_MMU 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. Note that the kernel does not currently support SMP machines with 603/603e/603ev or PPC750 ("G3") processors since they have inadequate hardware support for multiprocessor operation. 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 N. config NR_CPUS int "Maximum number of CPUs (2-128)" range 2 128 depends on SMP default "32" if PPC64 default "4" # Although 750CXe (Gekko) seems to be cache coherent capable, the GAMECUBE # does not maintain cache coherency with respect to dma enabled devices # like the BBA, DI, ARAM, etc. # We need Y here if we want a working kernel dma api. config NOT_COHERENT_CACHE bool depends on 4xx || 8xx || E200 || GAMECUBE default y config CHECK_CACHE_COHERENCY bool endmenu |
