1 | Preface. |
2 | ||
3 | This is a new low-level driver to support analog joystick attached to | |
4 | Crystal SoundFusion CS4610/CS4612/CS4615. This code is based upon | |
5 | Vortex/Solo drivers as an example of decoration style, and ALSA | |
6 | 0.5.8a kernel drivers as an chipset documentation and samples. | |
7 | ||
8 | This version does not have cooked mode support; the basic code | |
9 | is present here, but have not tested completely. The button analysis | |
10 | is completed in this mode, but the axis movement is not. | |
11 | ||
12 | Raw mode works fine with analog joystick front-end driver and cs461x | |
13 | driver as a backend. I've tested this driver with CS4610, 4-axis and | |
14 | 4-button joystick; I mean the jstest utility. Also I've tried to | |
15 | play in xracer game using joystick, and the result is better than | |
16 | keyboard only mode. | |
17 | ||
18 | The sensitivity and calibrate quality have not been tested; the two | |
19 | reasons are performed: the same hardware cannot work under Win95 (blue | |
20 | screen in VJOYD); I have no documentation on my chip; and the existing | |
21 | behavior in my case was not raised the requirement of joystick calibration. | |
22 | So the driver have no code to perform hardware related calibration. | |
23 | ||
24 | The patch contains minor changes of Config.in and Makefile files. All | |
25 | needed code have been moved to one separate file cs461x.c like ns558.c | |
26 | This driver have the basic support for PCI devices only; there is no | |
27 | ISA or PnP ISA cards supported. AFAIK the ns558 have support for Crystal | |
28 | ISA and PnP ISA series. | |
29 | ||
fff9289b | 30 | The driver works with ALSA drivers simultaneously. For example, the xracer |
1da177e4 LT |
31 | uses joystick as input device and PCM device as sound output in one time. |
32 | There are no sound or input collisions detected. The source code have | |
33 | comments about them; but I've found the joystick can be initialized | |
d9195881 | 34 | separately of ALSA modules. So, you can use only one joystick driver |
1da177e4 LT |
35 | without ALSA drivers. The ALSA drivers are not needed to compile or |
36 | run this driver. | |
37 | ||
38 | There are no debug information print have been placed in source, and no | |
39 | specific options required to work this driver. The found chipset parameters | |
40 | are printed via printk(KERN_INFO "..."), see the /var/log/messages to | |
41 | inspect cs461x: prefixed messages to determine possible card detection | |
42 | errors. | |
