# sparc64 configuration mainmenu "Linux Kernel Configuration for 64-bit SPARC" config SPARC bool default y select HAVE_OPROFILE select HAVE_KPROBES select HAVE_KRETPROBES config SPARC64 bool default y select HAVE_FUNCTION_TRACER select HAVE_IDE select HAVE_LMB select HAVE_SYSCALL_WRAPPERS select HAVE_ARCH_KGDB select USE_GENERIC_SMP_HELPERS if SMP select HAVE_ARCH_TRACEHOOK select ARCH_WANT_OPTIONAL_GPIOLIB select RTC_CLASS select RTC_DRV_M48T59 select RTC_DRV_CMOS select RTC_DRV_BQ4802 select RTC_DRV_SUN4V select RTC_DRV_STARFIRE config GENERIC_TIME bool default y config GENERIC_CMOS_UPDATE bool default y config GENERIC_CLOCKEVENTS bool default y config GENERIC_GPIO bool help Generic GPIO API support config 64BIT def_bool y config MMU bool default y config IOMMU_HELPER bool default y config QUICKLIST bool default y config STACKTRACE_SUPPORT bool default y config LOCKDEP_SUPPORT bool default y config ARCH_MAY_HAVE_PC_FDC bool default y config ARCH_HAS_ILOG2_U32 bool default n config ARCH_HAS_ILOG2_U64 bool default n config AUDIT_ARCH bool default y config HAVE_SETUP_PER_CPU_AREA def_bool y config ARCH_NO_VIRT_TO_BUS def_bool y config OF def_bool y config GENERIC_HARDIRQS_NO__DO_IRQ bool def_bool y source "init/Kconfig" source "kernel/Kconfig.freezer" menu "Processor type and features" choice prompt "Kernel page size" default SPARC64_PAGE_SIZE_8KB config SPARC64_PAGE_SIZE_8KB bool "8KB" help This lets you select the page size of the kernel. 8KB and 64KB work quite well, since SPARC ELF sections provide for up to 64KB alignment. If you don't know what to do, choose 8KB. config SPARC64_PAGE_SIZE_64KB bool "64KB" endchoice 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. source kernel/Kconfig.hz config HOTPLUG_CPU bool "Support for hot-pluggable CPUs" depends on SMP select HOTPLUG help Say Y here to experiment with turning CPUs off and on. CPUs can be controlled through /sys/devices/system/cpu/cpu#. Say N if you want to disable CPU hotplug. config GENERIC_HARDIRQS bool default y source "kernel/time/Kconfig" 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 N. config NR_CPUS int "Maximum number of CPUs (2-1024)" range 2 1024 depends on SMP default "64" source "drivers/cpufreq/Kconfig" config US3_FREQ tristate "UltraSPARC-III CPU Frequency driver" depends on CPU_FREQ select CPU_FREQ_TABLE help This adds the CPUFreq driver for UltraSPARC-III processors. For details, take a look at <file:Documentation/cpu-freq>. If in doubt, say N. config US2E_FREQ tristate "UltraSPARC-IIe CPU Frequency driver" depends on CPU_FREQ select CPU_FREQ_TABLE help This adds the CPUFreq driver for UltraSPARC-IIe processors. For details, take a look at <file:Documentation/cpu-freq>. If in doubt, say N. config US3_MC tristate "UltraSPARC-III Memory Controller driver" default y help This adds a driver for the UltraSPARC-III memory controller. Loading this driver allows exact mnemonic strings to be printed in the event of a memory error, so that the faulty DIMM on the motherboard can be matched to the error. If in doubt, say Y, as this information can be very useful. # Global things across all Sun machines. config GENERIC_LOCKBREAK bool default y depends on SMP && PREEMPT config RWSEM_GENERIC_SPINLOCK bool config RWSEM_XCHGADD_ALGORITHM bool default y config GENERIC_FIND_NEXT_BIT bool default y config GENERIC_HWEIGHT bool default y if !ULTRA_HAS_POPULATION_COUNT config GENERIC_CALIBRATE_DELAY bool default y choice prompt "SPARC64 Huge TLB Page Size" depends on HUGETLB_PAGE default HUGETLB_PAGE_SIZE_4MB config HUGETLB_PAGE_SIZE_4MB bool "4MB" config HUGETLB_PAGE_SIZE_512K bool "512K" config HUGETLB_PAGE_SIZE_64K depends on !SPARC64_PAGE_SIZE_64KB bool "64K" endchoice endmenu config NUMA bool "NUMA support" depends on SMP config NODES_SHIFT int default "4" depends on NEED_MULTIPLE_NODES # 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.

These are credit-card size devices such as network cards, modems or hard drives often used with laptops computers. There are actually two varieties of these cards: the older 16 bit PCMCIA cards and the newer 32 bit CardBus cards. If you want to use CardBus cards, you need to say Y here and also to "CardBus support" below. To use your PC-cards, you will need supporting software from David Hinds' pcmcia-cs package (see the file <file:Documentation/Changes> for location). Please also read the PCMCIA-HOWTO, available from <http://www.tldp.org/docs.html#howto>. To compile this driver as modules, choose M here: the modules will be called pcmcia_core and ds. config SBUS bool default y config SBUSCHAR bool default y config SUN_AUXIO bool default y config SUN_IO bool default y config SUN_LDOMS bool "Sun Logical Domains support" help Say Y here is you want to support virtual devices via Logical Domains. config PCI bool "PCI support" 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 source "drivers/pci/Kconfig" config SUN_OPENPROMFS tristate "Openprom tree appears in /proc/openprom" help If you say Y, the OpenPROM device tree will be available as a virtual file system, which you can mount to /proc/openprom by "mount -t openpromfs none /proc/openprom". To compile the /proc/openprom support as a module, choose M here: the module will be called openpromfs. If unsure, choose M. menu "Executable file formats" source "fs/Kconfig.binfmt" config COMPAT bool default y select COMPAT_BINFMT_ELF config SYSVIPC_COMPAT bool depends on COMPAT && SYSVIPC default y endmenu config SCHED_SMT bool "SMT (Hyperthreading) scheduler support" depends on SMP default y help SMT scheduler support improves the CPU scheduler's decision making when dealing with SPARC cpus at a cost of slightly increased overhead in some places. If unsure say N here. config SCHED_MC bool "Multi-core scheduler support" depends on SMP default y help Multi-core scheduler support improves the CPU scheduler's decision making when dealing with multi-core CPU chips at a cost of slightly increased overhead in some places. If unsure say N here. source "kernel/Kconfig.preempt" config CMDLINE_BOOL bool "Default bootloader kernel arguments" config CMDLINE string "Initial kernel command string" depends on CMDLINE_BOOL default "console=ttyS0,9600 root=/dev/sda1" help Say Y here if you want to be able to pass default arguments to the kernel. This will be overridden by the bootloader, if you use one (such as SILO). This is most useful if you want to boot a kernel from TFTP, and want default options to be available with having them passed on the command line. NOTE: This option WILL override the PROM bootargs setting! source "net/Kconfig" source "drivers/Kconfig" source "drivers/sbus/char/Kconfig" source "fs/Kconfig" source "arch/sparc64/Kconfig.debug" source "security/Kconfig" source "crypto/Kconfig" source "lib/Kconfig"
