- 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 witn ALSA drivers simultaneously. For exmple, 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 canm 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.
