Preface.
|
|
|
|
This is a new low-level driver to support analog joystick attached to
|
|
Crystal SoundFusion CS4610/CS4612/CS4615. This code is based upon
|
|
Vortex/Solo drivers as an example of decoration style, and ALSA
|
|
0.5.8a kernel drivers as an chipset documentation and samples.
|
|
|
|
This version does not have cooked mode support; the basic code
|
|
is present here, but have not tested completely. The button analysis
|
|
is completed in this mode, but the axis movement is not.
|
|
|
|
Raw mode works fine with analog joystick front-end driver and cs461x
|
|
driver as a backend. I've tested this driver with CS4610, 4-axis and
|
|
4-button joystick; I mean the jstest utility. Also I've tried to
|
|
play in xracer game using joystick, and the result is better than
|
|
keyboard only mode.
|
|
|
|
The sensitivity and calibrate quality have not been tested; the two
|
|
reasons are performed: the same hardware cannot work under Win95 (blue
|
|
screen in VJOYD); I have no documentation on my chip; and the existing
|
|
behavior in my case was not raised the requirement of joystick calibration.
|
|
So the driver have no code to perform hardware related calibration.
|
|
|
|
The patch contains minor changes of Config.in and Makefile files. All
|
|
needed code have been moved to one separate file cs461x.c like ns558.c
|
|
This driver have the basic support for PCI devices only; there is no
|
|
ISA or PnP ISA cards supported. AFAIK the ns558 have support for Crystal
|
|
ISA and PnP ISA series.
|
|
|
|
The driver works with ALSA drivers simultaneously. For example, the xracer
|
|
uses joystick as input device and PCM device as sound output in one time.
|
|
There are no sound or input collisions detected. The source code have
|
|
comments about them; but I've found the joystick can be initialized
|
|
separately of ALSA modules. So, you can use only one joystick driver
|
|
without ALSA drivers. The ALSA drivers are not needed to compile or
|
|
run this driver.
|
|
|
|
There are no debug information print have been placed in source, and no
|
|
specific options required to work this driver. The found chipset parameters
|
|
are printed via printk(KERN_INFO "..."), see the /var/log/messages to
|
|
inspect cs461x: prefixed messages to determine possible card detection
|
|
errors.
