config PCI_DOMAINS
	bool
	default PCI

config RTC
	tristate
	depends on PCI
	default y
	---help---
	  If you say Y here and create a character special file /dev/rtc with
	  major number 10 and minor number 135 using mknod ("man mknod"), you
	  will get access to the real time clock (or hardware clock) built
	  into your computer.

	  Every PC has such a clock built in. It can be used to generate
	  signals from as low as 1Hz up to 8192Hz, and can also be used
	  as a 24 hour alarm. It reports status information via the file
	  /proc/driver/rtc and its behaviour is set by various ioctls on
	  /dev/rtc.

	  If you run Linux on a multiprocessor machine and said Y to
	  "Symmetric Multi Processing" above, you should say Y here to read
	  and set the RTC in an SMP compatible fashion.

	  If you think you have a use for such a device (such as periodic data
	  sampling), then say Y here, and read <file:Documentation/rtc.txt>
	  for details.

	  To compile this driver as a module, choose M here: the
	  module will be called rtc.

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.

config SPARC32_COMPAT
	bool "Kernel support for Linux/Sparc 32bit binary compatibility"
	help
	  This allows you to run 32-bit binaries on your Ultra.
	  Everybody wants this; say Y.

config COMPAT
	bool
	depends on SPARC32_COMPAT
	default y

config UID16
	bool
	depends on SPARC32_COMPAT
	default y

config BINFMT_ELF32
	tristate "Kernel support for 32-bit ELF binaries"
	depends on SPARC32_COMPAT
	help
	  This allows you to run 32-bit Linux/ELF binaries on your Ultra.
	  Everybody wants this; say Y.

config BINFMT_AOUT32
	bool "Kernel support for 32-bit (ie. SunOS) a.out binaries"
	depends on SPARC32_COMPAT
	help
	  This allows you to run 32-bit a.out format binaries on your Ultra.
	  If you want to run SunOS binaries (see SunOS binary emulation below)
	  or other a.out binaries, say Y. If unsure, say N.

source "fs/Kconfig.binfmt"

config SUNOS_EMUL
	bool "SunOS binary emulation"
	depends on BINFMT_AOUT32
	help
	  This allows you to run most SunOS binaries.  If you want to do this,
	  say Y here and place appropriate files in /usr/gnemul/sunos. See
	  <http://www.ultralinux.org/faq.html> for more information.  If you
	  want to run SunOS binaries on an Ultra you must also say Y to
	  "Kernel support for 32-bit a.out binaries" above.

config SOLARIS_EMUL
	tristate "Solaris binary emulation (EXPERIMENTAL)"
	depends on SPARC32_COMPAT && EXPERIMENTAL
	help
	  This is experimental code which will enable you to run (many)
	  Solaris binaries on your SPARC Linux machine.

	  To compile this code as a module, choose M here: the
	  module will be called solaris.

source "drivers/parport/Kconfig"

config PRINTER
	tristate "Parallel printer support"
	depends on PARPORT
	---help---
	  If you intend to attach a printer to the parallel port of your Linux
	  box (as opposed to using a serial printer; if the connector at the
	  printer has 9 or 25 holes ["female"], then it's serial), say Y.
	  Also read the Printing-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>.

	  It is possible to share one parallel port among several devices
	  (e.g. printer and ZIP drive) and it is safe to compile the
	  corresponding drivers into the kernel.
	  To compile this driver as a module, choose M here and read
	  <file:Documentation/parport.txt>.  The module will be called lp.

	  If you have several parallel ports, you can specify which ports to
	  use with the "lp" kernel command line option.  (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.)  The syntax of the
	  "lp" command line option can be found in <file:drivers/char/lp.c>.

	  If you have more than 8 printers, you need to increase the LP_NO
	  macro in lp.c and the PARPORT_MAX macro in parport.h.

config ENVCTRL
	tristate "SUNW, envctrl support"
	depends on PCI
	help
	  Kernel support for temperature and fan monitoring on Sun SME
	  machines.

	  To compile this driver as a module, choose M here: the
	  module will be called envctrl.

config DISPLAY7SEG
	tristate "7-Segment Display support"
	depends on PCI
	---help---
	  This is the driver for the 7-segment display and LED present on
	  Sun Microsystems CompactPCI models CP1400 and CP1500.

	  To compile this driver as a module, choose M here: the
	  module will be called display7seg.

	  If you do not have a CompactPCI model CP1400 or CP1500, or
	  another UltraSPARC-IIi-cEngine boardset with a 7-segment display,
	  you should say N to this option.

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!

menu "Unix98 PTY support"

config UNIX98_PTYS
	bool "Unix98 PTY support"
	---help---
	  A pseudo terminal (PTY) is a software device consisting of two
	  halves: a master and a slave. The slave device behaves identical to
	  a physical terminal; the master device is used by a process to
	  read data from and write data to the slave, thereby emulating a
	  terminal. Typical programs for the master side are telnet servers
	  and xterms.

	  Linux has traditionally used the BSD-like names /dev/ptyxx for
	  masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
	  has a number of problems. The GNU C library glibc 2.1 and later,
	  however, supports the Unix98 naming standard: in order to acquire a
	  pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
	  terminal is then made available to the process and the pseudo
	  terminal slave can be accessed as /dev/pts/<number>. What was
	  traditionally /dev/ttyp2 will then be /dev/pts/2, for example.

	  The entries in /dev/pts/ are created on the fly by a virtual
	  file system; therefore, if you say Y here you should say Y to
	  "/dev/pts file system for Unix98 PTYs" as well.

	  If you want to say Y here, you need to have the C library glibc 2.1
	  or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
	  Read the instructions in <file:Documentation/Changes> pertaining to
	  pseudo terminals. It's safe to say N.

config UNIX98_PTY_COUNT
	int "Maximum number of Unix98 PTYs in use (0-2048)"
	depends on UNIX98_PTYS
	default "256"
	help
	  The maximum number of Unix98 PTYs that can be used at any one time.
	  The default is 256, and should be enough for desktop systems. Server
	  machines which support incoming telnet/rlogin/ssh connections and/or
	  serve several X terminals may want to increase this: every incoming
	  connection and every xterm uses up one PTY.

	  When not in use, each additional set of 256 PTYs occupy
	  approximately 8 KB of kernel memory on 32-bit architectures.

menu "XFree86 DRI support"

config DRM
	bool "Direct Rendering Manager (XFree86 DRI support)"
	help
	  Kernel-level support for the Direct Rendering Infrastructure (DRI)
	  introduced in XFree86 4.0. If you say Y here, you need to select
	  the module that's right for your graphics card from the list below.
	  These modules provide support for synchronization, security, and
	  DMA transfers. Please see <http://dri.sourceforge.net/> for more
	  details.  You should also select and configure AGP
	  (/dev/agpgart) support.

config DRM_FFB
	tristate "Creator/Creator3D"
	depends on DRM
	help
	  Choose this option if you have one of Sun's Creator3D-based graphics
	  and frame buffer cards.  Product page at
	  <http://www.sun.com/desktop/products/Graphics/creator3d.html>.

config DRM_TDFX
	tristate "3dfx Banshee/Voodoo3+"
	depends on DRM
	help
	  Choose this option if you have a 3dfx Banshee or Voodoo3 (or later),
	  graphics card.  If M is selected, the module will be called tdfx.

config DRM_R128
	tristate "ATI Rage 128"
	depends on DRM
	help
	  Choose this option if you have an ATI Rage 128 graphics card.  If M
	  is selected, the module will be called r128.  AGP support for
	  this card is strongly suggested (unless you have a PCI version).
