Ok I sat down with Ken (the benefits of being in the same office)
and after a lengthy discussion I have come to terms with how it may
not be the most ideal plan to put the joystick driver into the
graphics driver. However I am still of the strong opinion that we
need some sort of better joystick architecture and I know Alexandre
is also of the like mindset.
One more thing that makes merging this into the graphics driver a bad
idea: Assume we have a Wayland graphics driver one day. It would run
on Linux, just like winex11. The way we talk to joysticks would be the
same though.
...
Now completely unresearched but it may be possible to make a single
joystick driver, maybe replacing winejoystick.drv that would build
only the platform code that is relevant.
I'm OK with that, but I don't think my opinion actually matters.
...
but before I do another big chunk of work I am seeking some
community buy-in and not just discuss with with Alexandre. I
understand if the USB driver path gets actually fleshed out and we
try to support Joysticks via that then all this separate driver
work would fall away and be replaced.
What do you mean with USB? Have support for USB devices and talk to
the raw USB device? In a way loading Windows joystick drivers or write
our own?
If this is the plan, does this work well in practise? The permissions
for accessing a USB device and an input device may be different. There
are non-USB joysticks. (Gameport, and nowadays hard drives have
acceleration sensors that get exposed as joysticks, but this may work
via fake USB devices)

There's another issue that may be related: When I play a game with a
joystick I usually don't touch my mouse or keyboard. That results in
the monitor going into standby after the standby timeout expired. I
suspect that d3d is supposed to disable screensavers (there are flags
that essenially say don't disable my screensaver), though maybe the X
server is supposed to read the joystick in some way and recognize that
I am still using the computer.
