Re: [Xen-devel] [RFC] keymap support for PVFB

[Markus Armbruster <armbru@xxxxxxxxxx>]

Let's get the facts, all the facts, and nothing but the facts :)

For the keystroke in question:

1. On the same machine and X display that you use to run the VNC
   viewer: use xev to figure out key symbol and scan code.

2. Instrument the vncfb backend to display the key symbol received by
   on_kbd_event() and the Linux input layer key code passed to the
   frontend.

3. Instrument the frontend to display the key symbol received from the
   backend and stuffed into the input layer (input_handler() in
   xenkbd.c).

4. In the guest, with the X display on the PVFB: use xev to figure out
   key symbol and scan code.

Do you need help with any of that?
