The keyboard it is a capacitive keyboard consisting of 20 keys. I've
adapted a very simple SPI driver to access to him, but the driver
(management commands, et al ) are implemented in user space. The access
to keymap is doing polling (so threads of timers in input method should
be used).

The keyboard is a multikey and the client is interested in use short key
press and long key presses.

The keymap returns a bitmap with the keys pressed, from here I create a
vector<uint8_t> with the key pressed ordered. I was thinking to create a
map of pair<vector of keys, pressed_time> to 'X11 key code'.

What do you think about that?

I've taken a fast look. It looks like that it I was looking for.
