There is now a new version of the patch. There has been no feedback from any others, even when there vere some bugs.
Get it from here: http://www.hut.fi/~mkohtala/newtty.diff
This patch is to make the virtual terminal tty devices be a configuration option. This is of use to those wanting to run Linux on machines that have no video or keyboard hardware.
The patch is needed by few groups porting Linux to MVME or other embedded systems. However, this is just about all I can do to it without your feedback.
The patch defines three new CONFIG_ macros CONFIG_VT for inclusion of console, vt, vc_screen, consolemap, selection, keyboard and defkeymap CONFIG_VT_CONSOLE for directing printk to the VT device CONFIG_VT_SERIAL for directing printk to the standard serial device
Both CONFIG_VT_CONSOLE and CONFIG_VT_SERIAL can be used together in which case the output goes to both. To support this, there is a new console device list with entries for this output. The list also has entries for waiting a key press and for determining what device really to open for /dev/console, but these are used only from the device at the head of the list.
The rest of the change is to move some code from tty_io.c to other files where it seems to fit better. This avoids some #ifdef CONFIG_VT / #endif.
