- bool "Enable Scrollback Buffer in System RAM"
- depends on VGA_CONSOLE
- default n
- help
- The scrollback buffer of the standard VGA console is located in
- the VGA RAM. The size of this RAM is fixed and is quite small.
- If you require a larger scrollback buffer, this can be placed in
- System RAM which is dynamically allocated during initialization.
- Placing the scrollback buffer in System RAM will slightly slow
- down the console.
-
- If you want this feature, say 'Y' here and enter the amount of
- RAM to allocate for this buffer. If unsure, say 'N'.

-config VGACON_SOFT_SCROLLBACK_SIZE

- depends on VGACON_SOFT_SCROLLBACK
- range 1 1024
- default "64"
- help
- Enter the amount of System RAM to allocate for scrollback
- buffers of VGA consoles. Each 64KB will give you approximately
- 16 80x25 screenfuls of scrollback buffer.
-
-config VGACON_SOFT_SCROLLBACK_PERSISTENT_ENABLE_BY_DEFAULT
- bool "Persistent Scrollback History for each console by default"
- depends on VGACON_SOFT_SCROLLBACK
- default n
- help
- Say Y here if the scrollback history should persist by default when
- switching between consoles. Otherwise, the scrollback history will be
- flushed each time the console is switched. This feature can also be
- enabled using the boot command line parameter
- 'vgacon.scrollback_persistent=1'.
-
- This feature might break your tool of choice to flush the scrollback
- buffer, e.g. clear(1) will work fine but Debian's clear_console(1)
- will be broken, which might cause security issues.
- You can use the escape sequence \e[3J instead if this feature is
- activated.
-
- Note that a buffer of VGACON_SOFT_SCROLLBACK_SIZE is taken for each
- created tty device.
- So if you use a RAM-constrained system, say N here.
