default y
---help---
If you say Y here, you will get support for terminal devices with
display and keyboard devices. These are called "virtual" because you
can run several virtual terminals (also called virtual consoles) on
one physical terminal. This is rather useful, for example one
virtual terminal can collect system messages and warnings, another
one can be used for a text-mode user session, and a third could run
an X session, all in parallel. Switching between virtual terminals
is done with certain key combinations, usually Alt-<function key>.
The setterm command ("man setterm") can be used to change the
properties (such as colors or beeping) of a virtual terminal. The
man page console_codes(4) ("man console_codes") contains the special
character sequences that can be used to change those properties
directly. The fonts used on virtual terminals can be changed with
the setfont ("man setfont") command and the key bindings are defined
with the loadkeys ("man loadkeys") command.
You need at least one virtual terminal device in order to make use
of your keyboard and monitor. Therefore, only people configuring an
embedded system would want to say N here in order to save some
memory; the only way to log into such a system is then via a serial
or network connection.
If unsure, say Y, or else you won't be able to do much with your new
shiny Linux system :-)
config VT_CONSOLE
bool
default y
---help---
The system console is the device which receives all kernel messages
and warnings and which allows logins in single user mode. If you
answer Y here, a virtual terminal (the device used to interact with
a physical terminal) can be used as system console. This is the most
common mode of operations, so you should say Y here unless you want
the kernel messages be output only to a serial port (in which case
you should say Y to "Console on serial port", below).
If you do say Y here, by default the currently visible virtual
terminal (/dev/tty0) will be used as system console. You can change
that with a kernel command line option such as "console=tty3" which
would use the third virtual terminal as system console. (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 unsure, say Y.

/*
* sata_sil24.c - Driver for Silicon Image 3124/3132 SATA-2 controllers
*
* Copyright 2005 Tejun Heo
*
* Based on preview driver from Silicon Image.
*
* NOTE: No NCQ/ATAPI support yet. The preview driver didn't support
* NCQ nor ATAPI, and, unfortunately, I couldn't find out how to make
* those work. Enabling those shouldn't be difficult. Basic
* structure is all there (in libata-dev tree). If you have any
* information about this hardware, please contact me or linux-ide.
* Info is needed on...
*
* - How to issue tagged commands and turn on sactive on issue accordingly.
* - Where to put an ATAPI command and how to tell the device to send it.
* - How to enable/use 64bit.

inode instead of a vfs inode as parameter.
- Fix the definition of the CHKD ntfs record magic. It had an off by
two error causing it to be CHKB instead of CHKD.
- Fix a stupid bug in __ntfs_bitmap_set_bits_in_run() which caused the
count to become negative and hence we had a wild memset() scribbling
all over the system's ram.
2.1.23 - Implement extension of resident files and make writing safe as well as
many bug fixes, cleanups, and enhancements...
