ALSA: usb-audio: refactor code

2010-03-05T07:17:14+00:00

Clean up the usb audio driver by factoring out a lot of functions to separate files. Code for procfs, quirks, urbs, format parsers etc all got a new home now. Moved almost all special quirk handling to quirks.c and introduced new generic functions to handle them, so the exceptions do not pollute the whole driver. Renamed usbaudio.c to card.c because this is what it actually does now. Renamed usbmidi.c to midi.c for namespace clarity. Removed more things from usbaudio.h. The non-standard drivers were adopted accordingly. Signed-off-by: Daniel Mack Cc: Clemens Ladisch Signed-off-by: Takashi Iwai

ALSA: usb-audio: header file cleanups

2010-03-05T07:16:47+00:00

Rename snd-usb-lib to snd-usbmidi-lib as MIDI functions are the only thing it actually contains. Introduce a new header file to only declare these functions. Introduced usbmixer.h for all functions exported by usbmixer.c. Signed-off-by: Daniel Mack Cc: Clemens Ladisch Signed-off-by: Takashi Iwai

ALSA: usbaudio: consolidate header files

2010-02-23T07:51:56+00:00

Use the definitions from linux/usb/audio.h all over the ALSA USB audio driver and add some missing definitions there as well. Use the endpoint attribute macros from linux/usb/ch9 and remove the own things from sound/usb/usbaudio.h. Now things are also nicely prefixed which makes understanding the code easier.

ALSA: USB MIDI support for Access Music VirusTI

2010-02-16T08:34:56+00:00

Here's a patch that adds MIDI support through USB for one of the Access Music synths, the VirusTI. The synth uses standard USBMIDI protocol on its USB interface 3, although it does signal "vendor specific" class. A magic string has to be sent on interface 3 to enable the sending of MIDI from the synth (this string was found by sniffing usb communication of the Windows driver). This is all my patch does, and it works on my computer. Please note that the synth can also do standard usb audio I/O on its interfaces 2&3, which already works with the current snd-usb-audio driver, except for the audio input from the synth. I'm going to work on it when I have some time. Signed-off-by: Sebastien Alaiwan Signed-off-by: Clemens Ladisch (cosmetics, list terminator) Signed-off-by: Jaroslav Kysela

ALSA: usb-audio: reduce MIDI packet size to work around broken firmware

2010-02-16T07:08:01+00:00

Extend the list of devices whose firmware does not expect more than one USB MIDI packet in one USB packet. bug report: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3752 Signed-off-by: Clemens Ladisch Cc: Signed-off-by: Jaroslav Kysela

sound: usb: make the USB MIDI module more independent

2009-11-24T09:19:59+00:00

Remove the dependecy from the USB MIDI code on the snd_usb_audio structure. This allows using the USB MIDI module from another driver without having to pretend to be the generic USB audio driver. Signed-off-by: Clemens Ladisch Signed-off-by: Takashi Iwai

sound: usb-audio: allow switching altsetting on Roland USB MIDI devices

2009-11-24T09:19:49+00:00

Add a mixer control to select between the two altsettings on Roland USB MIDI devices where the input endpoint is either bulk or interrupt. Signed-off-by: Clemens Ladisch Signed-off-by: Takashi Iwai

ALSA: sound: usbmidi: Use hweight16

2009-11-20T07:46:26+00:00

Use hweight16 instead of Brian Kernighan's/Peter Wegner's method Signed-off-by: Akinobu Mita Signed-off-by: Takashi Iwai

sound: usb-audio: add MIDI drain callback

2009-07-15T09:56:41+00:00

When draining, instead of waiting for fifty milliseconds, just wait for the currently active URBs to complete. This cuts the usual waiting time down to one USB frame, or zero in the common case when there is no URB. Signed-off-by: Clemens Ladisch Signed-off-by: Takashi Iwai
