ALSA: usb-audio: Expose sample resolution through proc interface

2019-02-18T08:36:09+00:00

At least some USB devices use (MSB-aligned) audio format larger than the actual resolution of the device. In order to expose the actual device resolution (bBitResolution), add extra field to the procfs stream info interface. Signed-off-by: Jussi Laako Signed-off-by: Takashi Iwai

treewide: kmalloc() -> kmalloc_array()

2018-06-12T23:19:22+00:00

The kmalloc() function has a 2-factor argument form, kmalloc_array(). This patch replaces cases of: kmalloc(a * b, gfp) with: kmalloc_array(a * b, gfp) as well as handling cases of: kmalloc(a * b * c, gfp) with: kmalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kmalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kmalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The tools/ directory was manually excluded, since it has its own implementation of kmalloc(). The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kmalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kmalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

ALSA: usb-audio: silence a static checker warning

ALSA: usb: initial USB Audio Device Class 3.0 support

2018-03-21T10:46:33+00:00

Recently released USB Audio Class 3.0 specification introduces many significant changes comparing to previous versions, like - new Power Domains, support for LPM/L1 - new Cluster descriptor - changed layout of all class-specific descriptors - new High Capability descriptors - New class-specific String descriptors - new and removed units - additional sources for interrupts - removed Type II Audio Data Formats - ... and many other things (check spec) It also provides backward compatibility through multiple configurations, as well as requires mandatory support for BADD (Basic Audio Device Definition) on each ADC3.0 compliant device This patch adds initial support of UAC3 specification that is enough for Generic I/O Profile (BAOF, BAIF) device support from BADD document.

ALSA: usb-audio: Fix audio output on Roland SC-D70 sound module

2015-04-21T05:59:10+00:00

Roland SC-D70 reports its device class as vendor specific class and the quirk QUIRK_AUDIO_FIXED_ENDPOINT was used for audio output. In the quirks table the sampling rate was hard-coded to 44100 Hz and therefore not worked when the sound module was in 48000 Hz mode. In this change the quirk is changed to QUIRK_AUDIO_STANDARD_INTERFACE but as the sound module reports incorrect bSubframeSize in its descriptors, additional change is made in format.c to detect it and to override it (which uses the existing code for Edirol SD-90). Tested both when the sound module was in 44100 Hz mode and 48000 Hz mode and both audio input and output. MIDI related part of the driver is not touched.

ALSA: usb-audio: Use standard printk helpers

2014-02-26T15:45:34+00:00

Convert with dev_err() and co from snd_printk(), etc. As there are too deep indirections (e.g. ep->chip->dev->dev), a few new local macros, usb_audio_err() & co, are introduced. Also, the device numbers in some messages are dropped, as they are shown in the prefix automatically. Signed-off-by: Takashi Iwai
