[Xen-devel] Where's Xen VGA console kbd driver?

[Xen-devel] Where's Xen VGA console kbd driver?

[Roman Shaposhnik]

Hi!

here's a silly question: whenever Xen is provided with a VGA console,
where's the keyboard driver coming from? Quick to my surprise, my
casual inspection of the drivers/ folder didn't reveal much.

Did I miss something obvious?

Thanks,
Roman.

It's in qemu, see qemu/hw/display/xenfb.c in the source tree

How do "VGA console" and "keyboard driver" match up? The former
is an output device; in Xen there simply is no input counterpart.
If you need one with both input and output, you'll need to make
use of a serial console, not the VGA one.

This answers it perfectly! Thank you Jan.
