1======================================= 2Analog Joystick Support on ALSA Drivers 3======================================= 4 5Oct. 14, 2003 6 7Takashi Iwai <tiwai@suse.de> 8 9General 10------- 11 12First of all, you need to enable GAMEPORT support on Linux kernel for 13using a joystick with the ALSA driver. For the details of gameport 14support, refer to Documentation/input/joydev/joystick.rst. 15 16The joystick support of ALSA drivers is different between ISA and PCI 17cards. In the case of ISA (PnP) cards, it's usually handled by the 18independent module (ns558). Meanwhile, the ALSA PCI drivers have the 19built-in gameport support. Hence, when the ALSA PCI driver is built 20in the kernel, CONFIG_GAMEPORT must be 'y', too. Otherwise, the 21gameport support on that card will be (silently) disabled. 22 23Some adapter modules probe the physical connection of the device at 24the load time. It'd be safer to plug in the joystick device before 25loading the module. 26 27 28PCI Cards 29--------- 30 31For PCI cards, the joystick is enabled when the appropriate module 32option is specified. Some drivers don't need options, and the 33joystick support is always enabled. In the former ALSA version, there 34was a dynamic control API for the joystick activation. It was 35changed, however, to the static module options because of the system 36stability and the resource management. 37 38The following PCI drivers support the joystick natively. 39 40============== ============= ============================================ 41Driver Module Option Available Values 42============== ============= ============================================ 43als4000 joystick_port 0 = disable (default), 1 = auto-detect, 44 manual: any address (e.g. 0x200) 45au88x0 N/A N/A 46azf3328 joystick 0 = disable, 1 = enable, -1 = auto (default) 47ens1370 joystick 0 = disable (default), 1 = enable 48ens1371 joystick_port 0 = disable (default), 1 = auto-detect, 49 manual: 0x200, 0x208, 0x210, 0x218 50cmipci joystick_port 0 = disable (default), 1 = auto-detect, 51 manual: any address (e.g. 0x200) 52cs4281 N/A N/A 53cs46xx N/A N/A 54es1938 N/A N/A 55es1968 joystick 0 = disable (default), 1 = enable 56sonicvibes N/A N/A 57trident N/A N/A 58via82xx [#f1]_ joystick 0 = disable (default), 1 = enable 59ymfpci 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 66The following drivers don't support gameport natively, but there are 67additional modules. Load the corresponding module to add the gameport 68support. 69 70======= ================= 71Driver Additional Module 72======= ================= 73emu10k1 emu10k1-gp 74fm801 fm801-gp 75======= ================= 76 77Note: the "pcigame" and "cs461x" modules are for the OSS drivers only. 78These ALSA drivers (cs46xx, trident and au88x0) have the 79built-in gameport support. 80 81As mentioned above, ALSA PCI drivers have the built-in gameport 82support, so you don't have to load ns558 module. Just load "joydev" 83and the appropriate adapter module (e.g. "analog"). 84 85 86ISA Cards 87--------- 88 89ALSA ISA drivers don't have the built-in gameport support. 90Instead, you need to load "ns558" module in addition to "joydev" and 91the adapter module (e.g. "analog"). 92
