Are you actively testing gameport interfaces with real joysticks/gamepads on
these cards? And what software is still in use that runs on these old boxes
(with mainline kernel)?

There was a post to linux-input a few days ago when I ased if anyone woudl cry
over gameport going away.

If you take a look at gameport_measure_speed() in gameport.c you will see that
it counts cycles for timing, which obviously does not work that well when CPU
frequency changes.
The bugs have been opened in bugzilla/reported on lists ages ago but nobody
stepped up to fix that.

They have better chance of being supported ;) I had a couple a few years back
and they did work for me.

I really do not care about Microsoft and favors, I just go by the fact that
this hardware is becoming naturally extinct. And not only hardware, but also
software that uses it. Do you still play a lot of games with joysticks on such
hardware?
Thanks.
