So far, you've learned how to write the driver codes. And you might have a question now: how to put my own driver into the ALSA driver tree? Here (finally :) the standard procedure is described briefly.
Suppose that you create a new PCI driver for the card
“xyz”. The card module name would be
snd-xyz. The new driver is usually put into the alsa-driver
tree, alsa-driver/pci directory in
the case of PCI cards.
Then the driver is evaluated, audited and tested
by developers and users. After a certain time, the driver
will go to the alsa-kernel tree (to the corresponding directory,
such as alsa-kernel/pci) and eventually
will be integrated into the Linux 2.6 tree (the directory would be
linux/sound/pci).
In the following sections, the driver code is supposed to be put into alsa-driver tree. The two cases are covered: a driver consisting of a single source file and one consisting of several source files.
