# # For a description of the syntax of this configuration file, # see Documentation/kbuild/kconfig-language.txt. # config M68K bool default y select HAVE_AOUT select HAVE_IDE config MMU bool default y config RWSEM_GENERIC_SPINLOCK bool default y config RWSEM_XCHGADD_ALGORITHM bool config ARCH_HAS_ILOG2_U32 bool default n config ARCH_HAS_ILOG2_U64 bool default n config GENERIC_HWEIGHT bool default y config GENERIC_CALIBRATE_DELAY bool default y config TIME_LOW_RES bool default y config GENERIC_IOMAP bool default y config ARCH_MAY_HAVE_PC_FDC bool depends on BROKEN && (Q40 || SUN3X) default y config NO_IOPORT def_bool y config NO_DMA def_bool SUN3 config HZ int default 100 mainmenu "Linux/68k Kernel Configuration" source "init/Kconfig" source "kernel/Kconfig.freezer" menu "Platform dependent setup" config EISA bool ---help--- The Extended Industry Standard Architecture (EISA) bus was developed as an open alternative to the IBM MicroChannel bus. The EISA bus provided some of the features of the IBM MicroChannel bus while maintaining backward compatibility with cards made for the older ISA bus. The EISA bus saw limited use between 1988 and 1995 when it was made obsolete by the PCI bus. Say Y here if you are building a kernel for an EISA-based machine. Otherwise, say N. config MCA bool help MicroChannel Architecture is found in some IBM PS/2 machines and laptops. It is a bus system similar to PCI or ISA. See <file:Documentation/mca.txt> (and especially the web page given there) before attempting to build an MCA bus kernel. config PCMCIA tristate ---help--- Say Y here if you want to attach PCMCIA- or PC-cards to your Linux computer. 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 AMIGA bool "Amiga support" select MMU_MOTOROLA if MMU help This option enables support for the Amiga series of computers. If you plan to use this kernel on an Amiga, say Y here and browse the material available in <file:Documentation/m68k>; otherwise say N. config ATARI bool "Atari support" select MMU_MOTOROLA if MMU help This option enables support for the 68000-based Atari series of computers (including the TT, Falcon and Medusa). If you plan to use this kernel on an Atari, say Y here and browse the material available in <file:Documentation/m68k>; otherwise say N. config MAC bool "Macintosh support" select MMU_MOTOROLA if MMU help This option enables support for the Apple Macintosh series of computers (yes, there is experimental support now, at least for part of the series). Say N unless you're willing to code the remaining necessary support. ;) config NUBUS bool depends on MAC default y config M68K_L2_CACHE bool depends on MAC default y config APOLLO bool "Apollo support" select MMU_MOTOROLA if MMU help Say Y here if you want to run Linux on an MC680x0-based Apollo Domain workstation such as the DN3500. config VME bool "VME (Motorola and BVM) support" select MMU_MOTOROLA if MMU help Say Y here if you want to build a kernel for a 680x0 based VME board. Boards currently supported include Motorola boards MVME147, MVME162, MVME166, MVME167, MVME172, and MVME177. BVME4000 and BVME6000 boards from BVM Ltd are also supported. config MVME147 bool "MVME147 support" depends on VME help Say Y to include support for early Motorola VME boards. This will build a kernel which can run on MVME147 single-board computers. If you select this option you will have to select the appropriate drivers for SCSI, Ethernet and serial ports later on. config MVME16x bool "MVME162, 166 and 167 support" depends on VME help Say Y to include support for Motorola VME boards. This will build a kernel which can run on MVME162, MVME166, MVME167, MVME172, and MVME177 boards. If you select this option you will have to select the appropriate drivers for SCSI, Ethernet and serial ports later on. config BVME6000 bool "BVME4000 and BVME6000 support" depends on VME help Say Y to include support for VME boards from BVM Ltd. This will build a kernel which can run on BVME4000 and BVME6000 boards. If you select this option you will have to select the appropriate drivers for SCSI, Ethernet and serial ports later on. config HP300 bool "HP9000/300 and HP9000/400 support" select MMU_MOTOROLA if MMU help This option enables support for the HP9000/300 and HP9000/400 series of workstations. Support for these machines is still somewhat experimental. If you plan to try to use the kernel on such a machine say Y here. Everybody else says N. config DIO bool "DIO bus support" depends on HP300 default y help Say Y here to enable support for the "DIO" expansion bus used in HP300 machines. If you are using such a system you almost certainly want this. config SUN3X bool "Sun3x support" select MMU_MOTOROLA if MMU select M68030 help This option enables support for the Sun 3x series of workstations. Be warned that this support is very experimental. Note that Sun 3x kernels are not compatible with Sun 3 hardware. General Linux information on the Sun 3x series (now discontinued) is at <http://www.angelfire.com/ca2/tech68k/sun3.html>. If you don't want to compile a kernel for a Sun 3x, say N. config Q40 bool "Q40/Q60 support" select MMU_MOTOROLA if MMU help The Q40 is a Motorola 68040-based successor to the Sinclair QL manufactured in Germany. There is an official Q40 home page at <http://www.q40.de/>. This option enables support for the Q40 and Q60. Select your CPU below. For 68LC060 don't forget to enable FPU emulation. config SUN3 bool "Sun3 support" depends on !MMU_MOTOROLA select MMU_SUN3 if MMU select M68020 help This option enables support for the Sun 3 series of workstations (3/50, 3/60, 3/1xx, 3/2xx systems). Enabling this option requires that all other hardware types must be disabled, as Sun 3 kernels are incompatible with all other m68k targets (including Sun 3x!). If you don't want to compile a kernel exclusively for a Sun 3, say N. comment "Processor type" config M68020 bool "68020 support" help If you anticipate running this kernel on a computer with a MC68020 processor, say Y. Otherwise, say N. Note that the 68020 requires a 68851 MMU (Memory Management Unit) to run Linux/m68k, except on the Sun 3, which provides its own version. config M68030 bool "68030 support" depends on !MMU_SUN3 help If you anticipate running this kernel on a computer with a MC68030 processor, say Y. Otherwise, say N. Note that a MC68EC030 will not work, as it does not include an MMU (Memory Management Unit). config M68040 bool "68040 support" depends on !MMU_SUN3 help If you anticipate running this kernel on a computer with a MC68LC040 or MC68040 processor, say Y. Otherwise, say N. Note that an MC68EC040 will not work, as it does not include an MMU (Memory Management Unit). config M68060 bool "68060 support" depends on !MMU_SUN3 help If you anticipate running this kernel on a computer with a MC68060 processor, say Y. Otherwise, say N. config MMU_MOTOROLA bool depends on MMU && !MMU_SUN3 config MMU_SUN3 bool depends on MMU && !MMU_MOTOROLA config M68KFPU_EMU bool "Math emulation support (EXPERIMENTAL)" depends on EXPERIMENTAL help At some point in the future, this will cause floating-point math instructions to be emulated by the kernel on machines that lack a floating-point math coprocessor. Thrill-seekers and chronically sleep-deprived psychotic hacker types can say Y now, everyone else should probably wait a while. config M68KFPU_EMU_EXTRAPREC bool "Math emulation extra precision" depends on M68KFPU_EMU help The fpu uses normally a few bit more during calculations for correct rounding, the emulator can (often) do the same but this extra calculation can cost quite some time, so you can disable it here. The emulator will then "only" calculate with a 64 bit mantissa and round slightly incorrect, what is more then enough for normal usage. config M68KFPU_EMU_ONLY bool "Math emulation only kernel" depends on M68KFPU_EMU help This option prevents any floating-point instructions from being compiled into the kernel, thereby the kernel doesn't save any floating point context anymore during task switches, so this kernel will only be usable on machines without a floating-point math coprocessor. This makes the kernel a bit faster as no tests needs to be executed whether a floating-point instruction in the kernel should be executed or not. config ADVANCED bool "Advanced configuration options" ---help--- This gives you access to some advanced options for the CPU. The defaults should be fine for most users, but these options may make it possible for you to improve performance somewhat if you know what you are doing. Note that the answer to this question won't directly affect the kernel: saying N will just cause the configurator to skip all the questions about these options. Most users should say N to this question. config RMW_INSNS bool "Use read-modify-write instructions" depends on ADVANCED ---help--- This allows to use certain instructions that work with indivisible read-modify-write bus cycles. While this is faster than the workaround of disabling interrupts, it can conflict with DMA ( = direct memory access) on many Amiga systems, and it is also said to destabilize other machines. It is very likely that this will cause serious problems on any Amiga or Atari Medusa if set. The only configuration where it should work are 68030-based Ataris, where it apparently improves performance. But you've been warned! Unless you really know what you are doing, say N. Try Y only if you're quite adventurous. config SINGLE_MEMORY_CHUNK bool "Use one physical chunk of memory only" if ADVANCED && !SUN3 default y if SUN3 select NEED_MULTIPLE_NODES help Ignore all but the first contiguous chunk of physical memory for VM purposes. This will save a few bytes kernel size and may speed up some operations. Say N if not sure. config 060_WRITETHROUGH bool "Use write-through caching for 68060 supervisor accesses" depends on ADVANCED && M68060 ---help--- The 68060 generally uses copyback caching of recently accessed data. Copyback caching means that memory writes will be held in an on-chip cache and only written back to memory some time later. Saying Y here will force supervisor (kernel) accesses to use writethrough caching. Writethrough caching means that data is written to memory straight away, so that cache and memory data always agree. Writethrough caching is less efficient, but is needed for some drivers on 68060 based systems where the 68060 bus snooping signal is hardwired on. The 53c710 SCSI driver is known to suffer from this problem. config ARCH_DISCONTIGMEM_ENABLE def_bool !SINGLE_MEMORY_CHUNK config NODES_SHIFT int default "3" depends on !SINGLE_MEMORY_CHUNK source "mm/Kconfig" endmenu menu "General setup" source "fs/Kconfig.binfmt" config ZORRO bool "Amiga Zorro (AutoConfig) bus support" depends on AMIGA help This enables support for the Zorro bus in the Amiga. If you have expansion cards in your Amiga that conform to the Amiga AutoConfig(tm) specification, say Y, otherwise N. Note that even expansion cards that do not fit in the Zorro slots but fit in e.g. the CPU slot may fall in this category, so you have to say Y to let Linux use these. config AMIGA_PCMCIA bool "Amiga 1200/600 PCMCIA support (EXPERIMENTAL)" depends on AMIGA && EXPERIMENTAL help Include support in the kernel for pcmcia on Amiga 1200 and Amiga 600. If you intend to use pcmcia cards say Y; otherwise say N. config STRAM_PROC bool "ST-RAM statistics in /proc" depends on ATARI help Say Y here to report ST-RAM usage statistics in /proc/stram. config HEARTBEAT bool "Use power LED as a heartbeat" if AMIGA || APOLLO || ATARI || MAC ||Q40 default y if !AMIGA && !APOLLO && !ATARI && !MAC && !Q40 && HP300 help Use the power-on LED on your machine as a load meter. The exact behavior is platform-dependent, but normally the flash frequency is a hyperbolic function of the 5-minute load average. # We have a dedicated heartbeat LED. :-) config PROC_HARDWARE bool "/proc/hardware support" help Say Y here to support the /proc/hardware file, which gives you access to information about the machine you're running on, including the model, CPU, MMU, clock speed, BogoMIPS rating, and memory size. config ISA bool depends on Q40 || AMIGA_PCMCIA || GG2 default y 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. Other bus systems are PCI, EISA, MicroChannel (MCA) or VESA. ISA is an older system, now being displaced by PCI; newer boards don't support it. If you have ISA, say Y, otherwise N. config GENERIC_ISA_DMA bool depends on Q40 || AMIGA_PCMCIA || GG2 default y config ZONE_DMA bool default y source "drivers/pci/Kconfig" source "drivers/zorro/Kconfig" endmenu source "net/Kconfig" source "drivers/Kconfig" menu "Character devices" config ATARI_MFPSER tristate "Atari MFP serial support" depends on ATARI ---help--- If you like to use the MFP serial ports ("Modem1", "Serial1") under Linux, say Y. The driver equally supports all kinds of MFP serial ports and automatically detects whether Serial1 is available. To compile this driver as a module, choose M here. Note for Falcon users: You also have an MFP port, it's just not wired to the outside... But you could use the port under Linux. config ATARI_MIDI tristate "Atari MIDI serial support" depends on ATARI help If you want to use your Atari's MIDI port in Linux, say Y. To compile this driver as a module, choose M here. config ATARI_DSP56K tristate "Atari DSP56k support (EXPERIMENTAL)" depends on ATARI && EXPERIMENTAL help If you want to be able to use the DSP56001 in Falcons, say Y. This driver is still experimental, and if you don't know what it is, or if you don't have this processor, just say N. To compile this driver as a module, choose M here. config AMIGA_BUILTIN_SERIAL tristate "Amiga builtin serial support" depends on AMIGA help If you want to use your Amiga's built-in serial port in Linux, answer Y. To compile this driver as a module, choose M here. config MULTIFACE_III_TTY tristate "Multiface Card III serial support" depends on AMIGA help If you want to use a Multiface III card's serial port in Linux, answer Y. To compile this driver as a module, choose M here. config GVPIOEXT tristate "GVP IO-Extender support" depends on PARPORT=n && ZORRO help If you want to use a GVP IO-Extender serial card in Linux, say Y. Otherwise, say N. config GVPIOEXT_LP tristate "GVP IO-Extender parallel printer support" depends on GVPIOEXT help Say Y to enable driving a printer from the parallel port on your GVP IO-Extender card, N otherwise. config GVPIOEXT_PLIP tristate "GVP IO-Extender PLIP support" depends on GVPIOEXT help Say Y to enable doing IP over the parallel port on your GVP IO-Extender card, N otherwise. config MAC_SCC tristate "Macintosh serial support" depends on MAC config MAC_HID bool depends on INPUT_ADBHID default y config HPDCA tristate "HP DCA serial support" depends on DIO && SERIAL_8250 help If you want to use the internal "DCA" serial ports on an HP300 machine, say Y here. config HPAPCI tristate "HP APCI serial support" depends on HP300 && SERIAL_8250 && EXPERIMENTAL help If you want to use the internal "APCI" serial ports on an HP400 machine, say Y here. config MVME147_SCC bool "SCC support for MVME147 serial ports" depends on MVME147 help This is the driver for the serial ports on the Motorola MVME147 boards. Everyone using one of these boards should say Y here. config SERIAL167 bool "CD2401 support for MVME166/7 serial ports" depends on MVME16x help This is the driver for the serial ports on the Motorola MVME166, 167, and 172 boards. Everyone using one of these boards should say Y here. config MVME162_SCC bool "SCC support for MVME162 serial ports" depends on MVME16x help This is the driver for the serial ports on the Motorola MVME162 and 172 boards. Everyone using one of these boards should say Y here. config BVME6000_SCC bool "SCC support for BVME6000 serial ports" depends on BVME6000 help This is the driver for the serial ports on the BVME4000 and BVME6000 boards from BVM Ltd. Everyone using one of these boards should say Y here. config DN_SERIAL bool "Support for DN serial port (dummy)" depends on APOLLO config SERIAL_CONSOLE bool "Support for serial port console" depends on (AMIGA || ATARI || MAC || SUN3 || SUN3X || VME || APOLLO) && (ATARI_MFPSER=y || ATARI_MIDI=y || MAC_SCC=y || AMIGA_BUILTIN_SERIAL=y || GVPIOEXT=y || MULTIFACE_III_TTY=y || SERIAL=y || MVME147_SCC || SERIAL167 || MVME162_SCC || BVME6000_SCC || DN_SERIAL) ---help--- If you say Y here, it will be possible to use a serial port as the system console (the system console is the device which receives all kernel messages and warnings and which allows logins in single user mode). This could be useful if some terminal or printer is connected to that serial port. Even if you say Y here, the currently visible virtual console (/dev/tty0) will still be used as the system console by default, but you can alter that using a kernel command line option such as "console=ttyS1". (Try "man bootparam" or see the documentation of your boot loader (lilo or loadlin) about how to pass options to the kernel at boot time.) If you don't have a VGA card installed and you say Y here, the kernel will automatically use the first serial line, /dev/ttyS0, as system console. If unsure, say N. endmenu source "fs/Kconfig" source "arch/m68k/Kconfig.debug" source "security/Kconfig" source "crypto/Kconfig" source "lib/Kconfig"
