1 Analog Joystick Support on ALSA Drivers 2 ======================================= 3 Oct. 14, 2003 4 Takashi Iwai <tiwai@suse.de> 5 6 General 7 ------- 8 9 First of all, you need to enable GAMEPORT support on Linux kernel for 10 using a joystick with the ALSA driver. For the details of gameport 11 support, refer to Documentation/input/joystick.txt. 12 13 The joystick support of ALSA drivers is different between ISA and PCI 14 cards. In the case of ISA (PnP) cards, it's usually handled by the 15 independent module (ns558). Meanwhile, the ALSA PCI drivers have the 16 built-in gameport support. Hence, when the ALSA PCI driver is built 17 in the kernel, CONFIG_GAMEPORT must be 'y', too. Otherwise, the 18 gameport support on that card will be (silently) disabled. 19 20 Some adapter modules probe the physical connection of the device at 21 the load time. It'd be safer to plug in the joystick device before 22 loading the module. 23 24 25 PCI Cards 26 --------- 27 28 For PCI cards, the joystick is enabled when the appropriate module 29 option is specified. Some drivers don't need options, and the 30 joystick support is always enabled. In the former ALSA version, there 31 was a dynamic control API for the joystick activation. It was 32 changed, however, to the static module options because of the system 33 stability and the resource management. 34 35 The following PCI drivers support the joystick natively. 36 37 Driver Module Option Available Values 38 --------------------------------------------------------------------------- 39 als4000 joystick_port 0 = disable (default), 1 = auto-detect, 40 manual: any address (e.g. 0x200) 41 au88x0 N/A N/A 42 azf3328 joystick 0 = disable, 1 = enable, -1 = auto (default) 43 ens1370 joystick 0 = disable (default), 1 = enable 44 ens1371 joystick_port 0 = disable (default), 1 = auto-detect, 45 manual: 0x200, 0x208, 0x210, 0x218 46 cmipci joystick_port 0 = disable (default), 1 = auto-detect, 47 manual: any address (e.g. 0x200) 48 cs4281 N/A N/A 49 cs46xx N/A N/A 50 es1938 N/A N/A 51 es1968 joystick 0 = disable (default), 1 = enable 52 sonicvibes N/A N/A 53 trident N/A N/A 54 via82xx(*1) joystick 0 = disable (default), 1 = enable 55 ymfpci joystick_port 0 = disable (default), 1 = auto-detect, 56 manual: 0x201, 0x202, 0x204, 0x205(*2) 57 --------------------------------------------------------------------------- 58 59 *1) VIA686A/B only 60 *2) With YMF744/754 chips, the port address can be chosen arbitrarily 61 62 The following drivers don't support gameport natively, but there are 63 additional modules. Load the corresponding module to add the gameport 64 support. 65 66 Driver Additional Module 67 ----------------------------- 68 emu10k1 emu10k1-gp 69 fm801 fm801-gp 70 ----------------------------- 71 72 Note: the "pcigame" and "cs461x" modules are for the OSS drivers only. 73 These ALSA drivers (cs46xx, trident and au88x0) have the 74 built-in gameport support. 75 76 As mentioned above, ALSA PCI drivers have the built-in gameport 77 support, so you don't have to load ns558 module. Just load "joydev" 78 and the appropriate adapter module (e.g. "analog"). 79 80 81 ISA Cards 82 --------- 83 84 ALSA ISA drivers don't have the built-in gameport support. 85 Instead, you need to load "ns558" module in addition to "joydev" and 86 the adapter module (e.g. "analog").
