config SERIAL_8250
tristate "8250/16550 and compatible serial support"
select SERIAL_CORE
---help---
This selects whether you want to include the driver for the standard
serial ports. The standard answer is Y. People who might say N
here are those that are setting up dedicated Ethernet WWW/FTP
servers, or users that have one of the various bus mice instead of a
serial mouse and don't intend to use their machine's standard serial
port for anything. (Note that the Cyclades and Stallion multi
serial port drivers do not need this driver built in for them to
work.)
To compile this driver as a module, choose M here: the
module will be called 8250.
[WARNING: Do not compile this driver as a module if you are using
non-standard serial ports, since the configuration information will
be lost when the driver is unloaded. This limitation may be lifted
in the future.]
BTW1: If you have a mouseman serial mouse which is not recognized by
the X window system, try running gpm first.
BTW2: If you intend to use a software modem (also called Winmodem)
under Linux, forget it. These modems are crippled and require
proprietary drivers which are only available under Windows.
Most people will say Y or M here, so that they can use serial mice,
modems and similar devices connecting to the standard serial ports.
config SERIAL_8250_DEPRECATED_OPTIONS
bool "Support 8250_core.* kernel options (DEPRECATED)"
depends on SERIAL_8250
default y
---help---
In 3.7 we renamed 8250 to 8250_core by mistake, so now we have to
accept kernel parameters in both forms like 8250_core.nr_uarts=4 and
8250.nr_uarts=4. We now renamed the module back to 8250, but if
anybody noticed in 3.7 and changed their userspace we still have to
keep the 8350_core.* options around until they revert the changes
they already did.
If 8250 is built as a module, this adds 8250_core alias instead.
If you did not notice yet and/or you have userspace from pre-3.7, it
is safe (and recommended) to say N here.
config SERIAL_8250_PNP
bool "8250/16550 PNP device support" if EXPERT
depends on SERIAL_8250 && PNP
default y
---help---
This builds standard PNP serial support. You may be able to
disable this feature if you only need legacy serial support.
config SERIAL_8250_CONSOLE
bool "Console on 8250/16550 and compatible serial port"
depends on SERIAL_8250=y
select SERIAL_CORE_CONSOLE
---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 (grub or 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.
You can set that using a kernel command line option such as
"console=uart8250,io,0x3f8,9600n8"
"console=uart8250,mmio,0xff5e0000,115200n8".
and it will switch to normal serial console when the corresponding
port is ready.
"earlycon=uart8250,io,0x3f8,9600n8"
"earlycon=uart8250,mmio,0xff5e0000,115200n8".
it will not only setup early console.
If unsure, say N.
config FIX_EARLYCON_MEM

config SERIAL_8250_GSC

config SERIAL_8250_DMA

depends on SERIAL_8250 && DMADEVICES=y
default SERIAL_8250
help
This builds DMA support that can be used with 8250/16650
compatible UART controllers that support DMA signaling.
config SERIAL_8250_PCI
tristate "8250/16550 PCI device support" if EXPERT
depends on SERIAL_8250 && PCI
default SERIAL_8250
help
This builds standard PCI serial support. You may be able to
disable this feature if you only need legacy serial support.
Saves about 9K.
config SERIAL_8250_HP300
tristate

default SERIAL_8250
config SERIAL_8250_CS
tristate "8250/16550 PCMCIA device support"

---help---
Say Y here to enable support for 16-bit PCMCIA serial devices,
including serial port cards, modems, and the modem functions of
multi-function Ethernet/modem cards. (PCMCIA- or PC-cards are
credit-card size devices often used with laptops.)
To compile this driver as a module, choose M here: the
module will be called serial_cs.
If unsure, say N.
config SERIAL_8250_NR_UARTS
int "Maximum number of 8250/16550 serial ports"
depends on SERIAL_8250
default "4"
help
Set this to the number of serial ports you want the driver
to support. This includes any ports discovered via ACPI or
PCI enumeration and any ports that may be added at run-time
via hot-plug, or any ISA multi-port serial cards.
config SERIAL_8250_RUNTIME_UARTS
int "Number of 8250/16550 serial ports to register at runtime"
depends on SERIAL_8250
range 0 SERIAL_8250_NR_UARTS
default "4"
help
Set this to the maximum number of serial ports you want
the kernel to register at boot time. This can be overridden
with the module parameter "nr_uarts", or boot-time parameter
8250.nr_uarts
config SERIAL_8250_EXTENDED
bool "Extended 8250/16550 serial driver options"
depends on SERIAL_8250
help
If you wish to use any non-standard features of the standard "dumb"
driver, say Y here. This includes HUB6 support, shared serial
interrupts, special multiport support, support for more than the
four COM 1/2/3/4 boards, etc.
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 serial driver options. If unsure, say N.
config SERIAL_8250_MANY_PORTS
bool "Support more than 4 legacy serial ports"
depends on SERIAL_8250_EXTENDED && !IA64
help
Say Y here if you have dumb serial boards other than the four
standard COM 1/2/3/4 ports. This may happen if you have an AST
FourPort, Accent Async, Boca (read the Boca mini-HOWTO, available
from <http://www.tldp.org/docs.html#howto>), or other custom
serial port hardware which acts similar to standard serial port
hardware. If you only use the standard COM 1/2/3/4 ports, you can

config SERIAL_8250_SHARE_IRQ
bool "Support for sharing serial interrupts"
depends on SERIAL_8250_EXTENDED
help
Some serial boards have hardware support which allows multiple dumb
serial ports on the same board to share a single IRQ. To enable
support for this in the serial driver, say Y here.
config SERIAL_8250_DETECT_IRQ
bool "Autodetect IRQ on standard ports (unsafe)"
depends on SERIAL_8250_EXTENDED
help
Say Y here if you want the kernel to try to guess which IRQ
to use for your serial port.
This is considered unsafe; it is far better to configure the IRQ in
a boot script using the setserial command.
If unsure, say N.
config SERIAL_8250_RSA
