General
|
||
|
|
-------
|
||
|
|
|
||
|
|
First of all, you need to enable GAMEPORT support on Linux kernel for
|
||
|
|
using a joystick with the ALSA driver. For the details of gameport
|
||
|
|
support, refer to Documentation/input/joystick.txt.
|
||
|
|
|
||
|
|
The joystick support of ALSA drivers is different between ISA and PCI
|
||
|
|
cards. In the case of ISA (PnP) cards, it's usually handled by the
|
||
|
|
independent module (ns558). Meanwhile, the ALSA PCI drivers have the
|
||
|
|
built-in gameport support. Hence, when the ALSA PCI driver is built
|
||
|
|
in the kernel, CONFIG_GAMEPORT must be 'y', too. Otherwise, the
|
||
|
|
gameport support on that card will be (silently) disabled.
|
||
|
|
|
||
|
|
Some adapter modules probe the physical connection of the device at
|
||
|
|
the load time. It'd be safer to plug in the joystick device before
|
||
|
|
loading the module.
|
||
|
|
|
||
|
|
|
||
|
|
PCI Cards
|
||
|
|
---------
|
||
|
|
|
||
|
|
For PCI cards, the joystick is enabled when the appropriate module
|
||
|
|
option is specified. Some drivers don't need options, and the
|
||
|
|
joystick support is always enabled. In the former ALSA version, there
|
||
|
|
was a dynamic control API for the joystick activation. It was
|
||
|
|
changed, however, to the static module options because of the system
|
||
|
|
stability and the resource management.
|
||
|
|
|
||
|
|
The following PCI drivers support the joystick natively.

The following drivers don't support gameport natively, but there are
|
||
|
|
additional modules. Load the corresponding module to add the gameport
|
||
|
|
support.

Driver Additional Module
|

|

-----------------------------
|

emu10k1 emu10k1-gp

|

|
|
|
||
|
|
Note: the "pcigame" and "cs461x" modules are for the OSS drivers only.
|
||
|
|
These ALSA drivers (cs46xx, trident and au88x0) have the
|
||
|
|
built-in gameport support.
|
||
|
|
|
||
|
|
As mentioned above, ALSA PCI drivers have the built-in gameport
|
||
|
|
support, so you don't have to load ns558 module. Just load "joydev"
|
||
|
|
and the appropriate adapter module (e.g. "analog").
|
||
|
|
|
||
|
|
|
||
|
|
ISA Cards
|
||
|
|
---------
|
||
|
|
|
||
|
|
ALSA ISA drivers don't have the built-in gameport support.
|
||
|
|
Instead, you need to load "ns558" module in addition to "joydev" and
|
||
|
|
the adapter module (e.g. "analog").
