Hi,
Finally found the time to put the wctablet code into shape. Here comes
the patch series.
Patch #1 is the submission by Anatoli, almost unmodified. I've only
adapted it to the recent chardev changes in the qemu code base so it
actually builds and works on current qemu.
The following patches improve the code base:
* various cleanups (codestyle, delete unused stuff).
* use accept_input insted of a timer.
* use new input interface to register the driver.
* rewrite command detection.
* added some helper functions.
* added trace events.
Functional changes:
* handle line speed changes.
* implement ST and SP commands.
See individual commit messages for more details.
Current state:
* wacom test application works.
* windows 3.11 driver works.
* linux guest fails (inputattach --wacom_iv). Probably due to '~C'
not being implemented, that is the last command sent by linux
before it throws an error.
* left button acts somewhat strange. One host side mouse click seems
to toggle the button state inside the guest (windows 3.11). Not sure
whenever that is a bug in the emulation or something the guest driver
is doing ...
cheers,
Gerd
