1Crystal SoundFusion CS4610/CS4612/CS461 joystick 2================================================ 3 4This is a new low-level driver to support analog joystick attached to 5Crystal SoundFusion CS4610/CS4612/CS4615. This code is based upon 6Vortex/Solo drivers as an example of decoration style, and ALSA 70.5.8a kernel drivers as an chipset documentation and samples. 8 9This version does not have cooked mode support; the basic code 10is present here, but have not tested completely. The button analysis 11is completed in this mode, but the axis movement is not. 12 13Raw mode works fine with analog joystick front-end driver and cs461x 14driver as a backend. I've tested this driver with CS4610, 4-axis and 154-button joystick; I mean the jstest utility. Also I've tried to 16play in xracer game using joystick, and the result is better than 17keyboard only mode. 18 19The sensitivity and calibrate quality have not been tested; the two 20reasons are performed: the same hardware cannot work under Win95 (blue 21screen in VJOYD); I have no documentation on my chip; and the existing 22behavior in my case was not raised the requirement of joystick calibration. 23So the driver have no code to perform hardware related calibration. 24 25This driver have the basic support for PCI devices only; there is no 26ISA or PnP ISA cards supported. 27 28The driver works with ALSA drivers simultaneously. For example, the xracer 29uses joystick as input device and PCM device as sound output in one time. 30There are no sound or input collisions detected. The source code have 31comments about them; but I've found the joystick can be initialized 32separately of ALSA modules. So, you can use only one joystick driver 33without ALSA drivers. The ALSA drivers are not needed to compile or 34run this driver. 35 36There are no debug information print have been placed in source, and no 37specific options required to work this driver. The found chipset parameters 38are printed via printk(KERN_INFO "..."), see the /var/log/messages to 39inspect cs461x: prefixed messages to determine possible card detection 40errors. 41 42Regards, 43Viktor
