| |
I wrote a patch 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 against 2.1.20 is at http://www.hut.fi/~mkohtala/newtty.diff.20
Please, check this patch out. I wish to have it tried by - maintainers of various architectures, I only use i386 - those porting Linux to MVME
If Linus does not pick the patch up from this message, I'll be mailing it to him in couple of weeks.
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.
