CONFIG_ARM
The ARM series is a line of low-power-consumption RISC chip designs
licensed by ARM ltd and targeted at embedded applications.
CONFIG_IDE
If you say Y here, your kernel will be able to manage low cost mass
storage units such as ATA/(E)IDE and ATAPI units. The most common
cases are IDE hard drives and ATAPI CD-ROM drives.
If your system is pure SCSI and doesn't use these interfaces, you
can say N here.
Integrated Disk Electronics (IDE aka ATA-1) is a connecting standard
for mass storage units such as hard disks. It was designed by
Western Digital and Compaq Computer in 1984. It was then named
ST506. Quite a number of disks use the IDE interface.
AT Attachment (ATA) is the superset of the IDE specifications.
ST506 was also called ATA-1.
Fast-IDE is ATA-2 (also named Fast ATA), Enhanced IDE (EIDE) is
ATA-3. It provides support for larger disks (up to 8.4GB by means of
the LBA standard), more disks (4 instead of 2) and for other mass
storage units such as tapes and cdrom. UDMA/33 (aka UltraDMA/33) is
ATA-4 and provides faster (and more CPU friendly) transfer modes
than previous PIO (Programmed processor Input/Output) from previous
ATA/IDE standards by means of fast DMA controllers.
ATA Packet Interface (ATAPI) is a protocol used by EIDE tape and
CD-ROM drives, similar in many respects to the SCSI protocol.
SMART IDE (Self Monitoring, Analysis and Reporting Technology) was
designed in order to prevent data corruption and disk crash by
detecting pre hardware failure conditions (heat, access time, and
the like...). Disks built since June 1995 may follow this standard.
The kernel itself don't manage this; however there are quite a
number of user programs such as smart that can query the status of
SMART parameters disk.
If you want to compile this driver as a module ( = code which can be
inserted in and removed from the running kernel whenever you want),
say M here and read <file:Documentation/modules.txt>. The module
will be called ide.o.
For further information, please read <file:Documentation/ide.txt>.
If unsure, say Y.
CONFIG_ISA
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_PREEMPT
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.
This allows applications to run more reliably even when the system is
under load.
Say Y here if you are building a kernel for a desktop, embedded
or real-time system. Say N if you are unsure.
CONFIG_MCA
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_EISA
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_HOTPLUG
Say Y here if you want to plug devices into your computer while
the system is running, and be able to use them quickly. In many
cases, the devices can likewise be unplugged at any time too.
One well known example of this is PCMCIA- or PC-cards, credit-card
size devices such as network cards, modems or hard drives which are
plugged into slots found on all modern laptop computers. Another
example, used on modern desktops as well as laptops, is USB.
Enable HOTPLUG and KMOD, and build a modular kernel. Get agent
software (at <http://linux-hotplug.sourceforge.net/>) and install it.
Then your kernel will automatically call out to a user mode "policy
agent" (/sbin/hotplug) to load modules and set up software needed
to use devices as you hotplug them.
CONFIG_KCORE_ELF
If you enabled support for /proc file system then the file
/proc/kcore will contain the kernel core image. This can be used
in gdb:
$ cd /usr/src/linux ; gdb vmlinux /proc/kcore
You have two choices here: ELF and A.OUT. Selecting ELF will make
/proc/kcore appear in ELF core format as defined by the Executable
and Linking Format specification. Selecting A.OUT will choose the
old "a.out" format which may be necessary for some old versions
of binutils or on some architectures.
This is especially useful if you have compiled the kernel with the
"-g" option to preserve debugging information. It is mainly used
for examining kernel data structures on the live kernel so if you
don't understand what this means or are not a kernel hacker, just
leave it at its default value ELF.
CONFIG_KCORE_AOUT
Not necessary unless you're using a very out-of-date binutils
version. You probably want KCORE_ELF.
CONFIG_BINFMT_ELF
ELF (Executable and Linkable Format) is a format for libraries and
executables used across different architectures and operating
systems. Saying Y here will enable your kernel to run ELF binaries
and enlarge it by about 13 KB. ELF support under Linux has now all
but replaced the traditional Linux a.out formats (QMAGIC and ZMAGIC)
because it is portable (this does *not* mean that you will be able
to run executables from different architectures or operating systems
however) and makes building run-time libraries very easy. Many new
executables are distributed solely in ELF format. You definitely
want to say Y here.
Information about ELF is contained in the ELF HOWTO available from
<http://www.linuxdoc.org/docs.html#howto>.
If you find that after upgrading from Linux kernel 1.2 and saying Y
here, you still can't run any ELF binaries (they just crash), then
you'll have to install the newest ELF runtime libraries, including
ld.so (check the file <file:Documentation/Changes> for location and
latest version).
If you want to compile this as a module ( = code which can be
inserted in and removed from the running kernel whenever you want),
say M here and read <file:Documentation/modules.txt>. The module
will be called binfmt_elf.o. Saying M or N here is dangerous because
some crucial programs on your system might be in ELF format.
CONFIG_BINFMT_AOUT
A.out (Assembler.OUTput) is a set of formats for libraries and
executables used in the earliest versions of UNIX. Linux used the
a.out formats QMAGIC and ZMAGIC until they were replaced with the
ELF format.
As more and more programs are converted to ELF, the use for a.out
will gradually diminish. If you disable this option it will reduce
your kernel by one page. This is not much and by itself does not
warrant removing support. However its removal is a good idea if you
wish to ensure that absolutely none of your programs will use this
older executable format. If you don't know what to answer at this
point then answer Y. If someone told you "You need a kernel with
QMAGIC support" then you'll have to say Y here. You may answer M to
compile a.out support as a module and later load the module when you
want to use a program or library in a.out format. The module will be
called binfmt_aout.o. Saying M or N here is dangerous though,
because some crucial programs on your system might still be in A.OUT
format.
CONFIG_BINFMT_MISC
If you say Y here, it will be possible to plug wrapper-driven binary
formats into the kernel. You will like this especially when you use
programs that need an interpreter to run like Java, Python or
Emacs-Lisp. It's also useful if you often run DOS executables under
the Linux DOS emulator DOSEMU (read the DOSEMU-HOWTO, available from
<http://www.linuxdoc.org/docs.html#howto>). Once you have
registered such a binary class with the kernel, you can start one of
those programs simply by typing in its name at a shell prompt; Linux
will automatically feed it to the correct interpreter.
You can do other nice things, too. Read the file
<file:Documentation/binfmt_misc.txt> to learn how to use this
feature, and <file:Documentation/java.txt> for information about how
to include Java support.
You must say Y to "/proc file system support" (CONFIG_PROC_FS) to
use this part of the kernel.
You may say M here for module support and later load the module when
you have use for it; the module is called binfmt_misc.o. If you
don't know what to answer at this point, say Y.
CONFIG_SCSI
If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
any other SCSI device under Linux, say Y and make sure that you know
the name of your SCSI host adapter (the card inside your computer
that "speaks" the SCSI protocol, also called SCSI controller),
because you will be asked for it.
You also need to say Y here if you want support for the parallel
port version of the 100 MB IOMEGA ZIP drive.
This driver is also available as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called scsi_mod.o. If you want to compile it as
a module, say M here and read <file:Documentation/modules.txt> and
<file:Documentation/scsi.txt>. However, do not compile this as a
module if your root file system (the one containing the directory /)
is located on a SCSI device.
CONFIG_NETDEVICES
You can say N here if you don't intend to connect your Linux box to
any other computer at all or if all your connections will be over a
telephone line with a modem either via UUCP (UUCP is a protocol to
forward mail and news between unix hosts over telephone lines; read
the UUCP-HOWTO, available from
<http://www.linuxdoc.org/docs.html#howto>) or dialing up a shell
account or a BBS, even using term (term is a program which gives you
almost full Internet connectivity if you have a regular dial up
shell account on some Internet connected Unix computer. Read
<http://www.bart.nl/~patrickr/term-howto/Term-HOWTO.html>).
You'll have to say Y if your computer contains a network card that
you want to use under Linux (make sure you know its name because you
will be asked for it and read the Ethernet-HOWTO (especially if you
plan to use more than one network card under Linux)) or if you want
to use SLIP (Serial Line Internet Protocol is the protocol used to
send Internet traffic over telephone lines or null modem cables) or
CSLIP (compressed SLIP) or PPP (Point to Point Protocol, a better
and newer replacement for SLIP) or PLIP (Parallel Line Internet
Protocol is mainly used to create a mini network by connecting the
parallel ports of two local machines) or AX.25/KISS (protocol for
sending Internet traffic over amateur radio links).
Make sure to read the NET-3-HOWTO. Eventually, you will have to read
Olaf Kirch's excellent and free book "Network Administrator's
Guide", to be found in <http://www.linuxdoc.org/docs.html#guide>. If
unsure, say Y.
CONFIG_MAGIC_SYSRQ
If you say Y here, you will have some control over the system even
if the system crashes for example during kernel debugging (e.g., you
will be able to flush the buffer cache to disk, reboot the system
immediately or dump some status information). This is accomplished
by pressing various keys while holding SysRq (Alt+PrintScreen). It
also works on a serial console (on PC hardware at least), if you
send a BREAK and then within 5 seconds a command keypress. The
keys are documented in <file:Documentation/sysrq.txt>. Don't say Y
unless you really know what this hack does.
CONFIG_ARCH_ARCA5K
This selects support for 'ARM26' CPUs (ARM 2 and 3)
CONFIG_ARCH_A5K
Say Y here to to support the Acorn A5000. Linux can support the
internal IDE disk and CD-ROM interface, serial and parallel port,
and the floppy drive. Note that on some A5000s the floppy is
plugged into the wrong socket on the motherboard.
CONFIG_ARCH_ARC
The Acorn Archimedes was an personal computer based on an 8MHz ARM2
processor, released in 1987. It supported 512K of RAM and 2 800K
floppy disks. Picture and more detailed specifications at
<http://www.computingmuseum.com/museum/archi.htm>.
CONFIG_PAGESIZE_16
Say Y here if your Archimedes or A5000 system has only 2MB of
memory, otherwise say N. The resulting kernel will not run on a
machine with 4MB of memory.
CONFIG_FPE_NWFPE
Say Y to include the NWFPE floating point emulator in the kernel.
This is necessary to run most binaries. Linux does not currently
support floating point hardware so you need to say Y here even if
your machine has an FPA or floating point co-processor podule.
It is also possible to say M to build the emulator as a module
(nwfpe.o) or indeed to leave it out altogether. However, unless you
know what you are doing this can easily render your machine
unbootable. Saying Y is the safe option.
You may say N here if you are going to load the Acorn FPEmulator
early in the bootup.
CONFIG_FPE_FASTFPE
Say Y here to include the FAST floating point emulator in the kernel.
This is an experimental much faster emulator which now also has full
precision for the mantissa. It does not support any exceptions.
It is very simple, and approximately 3-6 times faster than NWFPE.
It should be sufficient for most programs. It may be not suitable
for scientific calculations, but you have to check this for yourself.
If you do not feel you need a faster FP emulation you should better
choose NWFPE.
It is also possible to say M to build the emulator as a module
(fastfpe.o). But keep in mind that you should only load the FP
emulator early in the bootup. You should never change from NWFPE to
FASTFPE or vice versa in an active system!
CONFIG_DEBUG_ERRORS
This option controls verbose debugging information which can be
printed when the kernel detects an internal error. This debugging
information is useful to kernel hackers when tracking down problems,
but mostly meaningless to other people. It's safe to say Y unless
you are concerned with the code size or don't want to see these
messages.
CONFIG_NO_FRAME_POINTER
If you say Y here, the resulting kernel will be slightly smaller and
faster. However, when a problem occurs with the kernel, the
information that is reported is severely limited. Most people
should say N here.
CONFIG_DEBUG_USER
When a user program crashes due to an exception, the kernel can
print a brief message explaining what the problem was. This is
sometimes helpful for debugging but serves no purpose on a
production system. Most people should say N here.
CONFIG_DEBUG_INFO
Say Y here to include source-level debugging information in the
`vmlinux' binary image. This is handy if you want to use gdb or
addr2line to debug the kernel. It has no impact on the in-memory
footprint of the running kernel but it can increase the amount of
time and disk space needed for compilation of the kernel. If in
doubt say N.
CONFIG_DEBUG_LL
Say Y here to include definitions of printascii, printchar, printhex
in the kernel. This is helpful if you are debugging code that
executes before the console is initialized.
CONFIG_NO_PGT_CACHE
Normally the kernel maintains a `quicklist' of preallocated
pagetable structures in order to increase performance. On machines
with very few pages this may however be a loss. Say Y here to
disable the pgtable cache.
CONFIG_ARTHUR
Say Y here to include the kernel code necessary if you want to run
Acorn RISC OS/Arthur binaries under Linux. This code is still very
experimental; if this sounds frightening, say N and sleep in peace.
You can also say M here to compile this support as a module (which
will be called arthur.o).
CONFIG_CMDLINE
On some architectures (EBSA110 and CATS), there is currently no way
for the boot loader to pass arguments to the kernel. For these
architectures, you should supply some command-line options at build
time by entering them here. As a minimum, you should specify the
memory size and the root device (e.g., mem=64M root=/dev/nfs).
CONFIG_DEBUG_KERNEL
Say Y here if you are developing drivers or trying to debug and
identify kernel problems.
CONFIG_DEBUG_SLAB
Say Y here to have the kernel do limited verification on memory
allocation as well as poisoning memory on free to catch use of freed
memory.
CONFIG_DEBUG_SPINLOCK
Say Y here and build SMP to catch missing spinlock initialization
and certain other kinds of spinlock errors commonly made. This is
best used in conjunction with the NMI watchdog so that spinlock
deadlocks are also debuggable.
CONFIG_DEBUG_BUGVERBOSE
Say Y here to make BUG() panics output the file name and line number
of the BUG call as well as the EIP and oops trace. This aids
debugging but costs about 70-100K of memory.
CONFIG_ZBOOT_ROM
Say Y here if you intend to execute your compressed kernel image (zImage)
directly from ROM or flash. If unsure, say N.
CONFIG_ZBOOT_ROM_TEXT
The base address for zImage. Unless you have special requirements, you
should not change this value.
CONFIG_ZBOOT_ROM_BSS
The base address of 64KiB of read/write memory, which must be available
while the decompressor is running. Unless you have special requirements,
you should not change this value.
