1 | Crystal SoundFusion CS4610/CS4612/CS461 joystick |
2 | ================================================ | |
3 | ||
1da177e4 | 4 | This is a new low-level driver to support analog joystick attached to |
c87d6465 | 5 | Crystal SoundFusion CS4610/CS4612/CS4615. This code is based upon |
1da177e4 LT |
6 | Vortex/Solo drivers as an example of decoration style, and ALSA |
7 | 0.5.8a kernel drivers as an chipset documentation and samples. | |

9 | This version does not have cooked mode support; the basic code |
10 | is present here, but have not tested completely. The button analysis | |
11 | is completed in this mode, but the axis movement is not. | |
1da177e4 LT |
12 | |
13 | Raw mode works fine with analog joystick front-end driver and cs461x | |
c87d6465 | 14 | driver as a backend. I've tested this driver with CS4610, 4-axis and |
1da177e4 LT |
15 | 4-button joystick; I mean the jstest utility. Also I've tried to |
16 | play in xracer game using joystick, and the result is better than | |
17 | keyboard only mode. | |

19 | The sensitivity and calibrate quality have not been tested; the two | |
c87d6465 MCC |
20 | reasons are performed: the same hardware cannot work under Win95 (blue |
21 | screen in VJOYD); I have no documentation on my chip; and the existing | |
22 | behavior in my case was not raised the requirement of joystick calibration. | |
1da177e4 LT |
23 | So the driver have no code to perform hardware related calibration. |
24 | ||
1da177e4 | 25 | This driver have the basic support for PCI devices only; there is no |
b08c118c | 26 | ISA or PnP ISA cards supported. |
1da177e4 | 27 | |
fff9289b | 28 | The driver works with ALSA drivers simultaneously. For example, the xracer |
1da177e4 LT |
29 | uses joystick as input device and PCM device as sound output in one time. |
30 | There are no sound or input collisions detected. The source code have | |
c87d6465 | 31 | comments about them; but I've found the joystick can be initialized |
d9195881 | 32 | separately of ALSA modules. So, you can use only one joystick driver |
1da177e4 LT |
33 | without ALSA drivers. The ALSA drivers are not needed to compile or |
34 | run this driver. | |
35 | ||
36 | There are no debug information print have been placed in source, and no | |
37 | specific options required to work this driver. The found chipset parameters | |
38 | are printed via printk(KERN_INFO "..."), see the /var/log/messages to | |
c87d6465 | 39 | inspect cs461x: prefixed messages to determine possible card detection |
1da177e4 LT |
40 | errors. |
