Interested hackers are advised to have a read of linux/mm/swap.c and also make note of the goodies in

/proc/sys/vm. Kernels come with some useful documentation on this in the

linux/Documentation/vm/ directory.

The `buff=' Argument

Similar to the `swap=' argument, this allows the user to tune some of the parameters related to buffer memory

management. It accepts the following six parameters:

MAX_BUFF_AGE

BUFF_ADVANCE

BUFF_DECLINE

BUFF_INITIAL_AGE

BUFFEROUT_WEIGHT

BUFFERMEM_GRACE

3.4 Other Misc. Kernel Boot Arguments

These various boot arguments let the user tune certain internal kernel parameters.

The `acpi=' Argument

Currently this only accepts `off' to disable the ACPI subsystem.

The `console=' Argument

Usually the console is the 1st virtual terminal, and so boot messages appear on your VGA screen. Sometimes

it is nice to be able to use another device like a serial port (or even a printer!) to be the console when no video

device is present. It is also useful to capture boot time messages if a problem stops progress before they can be

logged to disk. An example would be to use console=ttyS1,9600 for selecting the 2nd serial port at

9600 baud to be the console. More information can be found in

linux/Documentation/serial−console.txt.

The `debug' Argument

The kernel communicates important (and not−so important) messages to the operator via the printk()

function. If the message is considered important, the printk() function will put a copy on the present

console as well as handing it off to the klogd() facility so that it gets logged to disk. The reason for printing

important messages to the console as well as logging them to disk is because under unfortunate circumstances

(e.g. a disk failure) the message won't make it to disk and will be lost.
