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 "Support for console on virtual terminal" - depends on VT - ---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.

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. - -source "drivers/char/pcmcia/Kconfig" - -source "drivers/serial/Kconfig" - -source "drivers/i2c/Kconfig" - -source "drivers/hwmon/Kconfig" - -source "drivers/usb/Kconfig" - -endmenu - -source "fs/Kconfig" - -source "arch/h8300/Kconfig.debug" - -source "security/Kconfig" - -source "crypto/Kconfig" - -source "lib/Kconfig" diff --git a/arch/h8300/Kconfig.cpu b/arch/h8300/Kconfig.cpu deleted file mode 100644 index 582797db960..00000000000 --- a/arch/h8300/Kconfig.cpu +++ /dev/null @@ -1,186 +0,0 @@ -menu "Processor type and features" - -choice - prompt "H8/300 platform" - default H8300H_GENERIC - -config H8300H_GENERIC - bool "H8/300H Generic" - help - H8/300H CPU Generic Hardware Support - -config H8300H_AKI3068NET - bool "AE-3068/69" - help - AKI-H8/3068F / AKI-H8/3069F Flashmicom LAN Board Support - More Information.
