1 ======================================= 2 Analog Joystick Support on ALSA Drivers 3 ======================================= 4 5 Oct. 14, 2003 6 7 Takashi Iwai <tiwai@suse.de> 8 9 General 10 ------- 11 12 First of all, you need to enable GAMEPORT support on Linux kernel for 13 using a joystick with the ALSA driver. For the details of gameport 14 support, refer to Documentation/input/joydev/joystick.rst. 15 16 The joystick support of ALSA drivers is different between ISA and PCI 17 cards. In the case of ISA (PnP) cards, it's usually handled by the 18 independent module (ns558). Meanwhile, the ALSA PCI drivers have the 19 built-in gameport support. Hence, when the ALSA PCI driver is built 20 in the kernel, CONFIG_GAMEPORT must be 'y', too. Otherwise, the 21 gameport support on that card will be (silently) disabled. 22 23 Some adapter modules probe the physical connection of the device at 24 the load time. It'd be safer to plug in the joystick device before 25 loading the module. 26 27 28 PCI Cards 29 --------- 30 31 For PCI cards, the joystick is enabled when the appropriate module 32 option is specified. Some drivers don't need options, and the 33 joystick support is always enabled. In the former ALSA version, there 34 was a dynamic control API for the joystick activation. It was 35 changed, however, to the static module options because of the system 36 stability and the resource management. 37 38 The following PCI drivers support the joystick natively. 39 40 ============== ============= ============================================ 41 Driver Module Option Available Values 42 ============== ============= ============================================ 43 als4000 joystick_port 0 = disable (default), 1 = auto-detect, 44 manual: any address (e.g. 0x200) 45 au88x0 N/A N/A 46 azf3328 joystick 0 = disable, 1 = enable, -1 = auto (default) 47 ens1370 joystick 0 = disable (default), 1 = enable 48 ens1371 joystick_port 0 = disable (default), 1 = auto-detect, 49 manual: 0x200, 0x208, 0x210, 0x218 50 cmipci joystick_port 0 = disable (default), 1 = auto-detect, 51 manual: any address (e.g. 0x200) 52 cs4281 N/A N/A 53 cs46xx N/A N/A 54 es1938 N/A N/A 55 es1968 joystick 0 = disable (default), 1 = enable 56 sonicvibes N/A N/A 57 trident N/A N/A 58 via82xx [#f1]_ joystick 0 = disable (default), 1 = enable 59 ymfpci joystick_port 0 = disable (default), 1 = auto-detect, 60 manual: 0x201, 0x202, 0x204, 0x205 [#f2]_ 61 ============== ============= ============================================ 62 63 .. [#f1] VIA686A/B only 64 .. [#f2] With YMF744/754 chips, the port address can be chosen arbitrarily 65 66 The following drivers don't support gameport natively, but there are 67 additional modules. Load the corresponding module to add the gameport 68 support. 69 70 ======= ================= 71 Driver Additional Module 72 ======= ================= 73 emu10k1 emu10k1-gp 74 fm801 fm801-gp 75 ======= ================= 76 77 Note: the "pcigame" and "cs461x" modules are for the OSS drivers only. 78 These ALSA drivers (cs46xx, trident and au88x0) have the 79 built-in gameport support. 80 81 As mentioned above, ALSA PCI drivers have the built-in gameport 82 support, so you don't have to load ns558 module. Just load "joydev" 83 and the appropriate adapter module (e.g. "analog"). 84 85 86 ISA Cards 87 --------- 88 89 ALSA ISA drivers don't have the built-in gameport support. 90 Instead, you need to load "ns558" module in addition to "joydev" and 91 the adapter module (e.g. "analog").
