Driver document for ALSA 0.9.x ?

Driver document for ALSA 0.9.x ?

[Alamy Liu]

Hi All,

I am viewing ALSA 0.5.0 Developer documentation at
http://www.math.tu-berlin.de/~sbartels/alsa/

I would like to know if there is any Developer documentation for
ALSA 0.9.x (or 0.8.x) available ?


Regards,

Alamy Liu

The docs generated by doxygen from the alsa-lib sources are available at
<http://www.alsa-project.org/alsa-doc/alsa-lib/>.

Arm based driver ?

[Alamy Liu]

Hi All,

  I am going to write a audio driver which connect to ARM based CPU 
directly using I2C and L3.
 From the developer's document. It seems the main structure are Card & 
Chipset.
In the Card layer, what kind of card driver should I implement ?
  A virtual-card ?  (exp : i2c/i2c-pxa250.c and l3/l3-pxa250.c 
(i2c/l3/l3-pxa250.c ?) )
Or there is another structure for such a situation ?

  Regards,

Alamy Liu

Drivers for I2C chips should go to: i2c/
Drivers for L3 chips should go to:  i2c/l3/
The card module should go to:       arm/

Those are documents for alsa-lib.  There are no such documents for the 
driver.

You can do as I did. Read the source for the drivers that are already 
there, then ask questions on the list as they arise. If you're lucky, 
Paul or Takashi will answer. If you can understand any of Jaroslav's 
posts, you are well on your way to being a driver writer.

seriously, i'd like to start documentation of ALSA driver tree, too.
at the first step, i'll try to write more comments in javadoc style
(which is largely used in kernel codes) on alsa driver sources.
then we can compile the complete document from them as an on-line
doc.

of course, there are other needs for documentation of ALSA.
if someone is interested in it, please let me know.
now is the good time to organize (again) the "documentation project".


ciao,

Takashi
