|\ | | | | | | | | Merging for-linus branch for syncing the latest STAC/IDT codec changes to be affected by the upcoming hda-jack rewrites.
| * ALSA: pcm: Fix the silence data for DSD formatsTakashi Iwai2014-08-221-2/+2
| | | | | | | | | | | | | | | | | | | | | | Right now we set 0 as the silence data for DSD_U8 and DSD_U16 formats, but this is actually wrong. 0 is rather the most negative value. Alternatively, we may take the repeating 0x69 pattern like ffmpeg deploys. Reference: https://ffmpeg.org/pipermail/ffmpeg-cvslog/2014-April/076427.html Suggested-by: Alexander E.

* | ALSA: pcm: add new DSD sampleformat for native DSD playback on XMOS based ↵Jurgen Kramer2014-09-081-0/+4
|/ | | | | | | | | | | | | | devices XMOS based USB DACs with native DSD support expose this feature via a USB alternate setting. The audio format is either 32-bit raw or a 32-bit PCM format. To utilize this feature on linux this patch introduces a new 32-bit DSD sampleformat DSD_U32_LE. A follow up patch will add a quirk for XMOS based devices to utilize the new format. Further patches will add support to alsa-lib. Signed-off-by: Jurgen Kramer <gtmkramer@xs4all.nl> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: Add helper function for intersecting two rate masksLars-Peter Clausen2014-01-141-0/+39
| | | | | | | | | | | | | | A bit of special care is necessary when creating the intersection of two rate masks. This comes from the special meaning of the SNDRV_PCM_RATE_CONTINUOUS and SNDRV_PCM_RATE_KNOT bits, which needs special handling when intersecting two rate masks. SNDRV_PCM_RATE_CONTINUOUS means the hardware supports all rates in a specific interval. SNDRV_PCM_RATE_KNOT means the hardware supports a set of discrete rates specified by a list constraint. For all other cases the supported rates are specified directly in the rate mask.

* ALSA: add DSD formatsDaniel Mack2013-04-181-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds two formats for Direct Stream Digital (DSD), a pulse-density encoding format which is described here: https://en.wikipedia.org/wiki/Direct_Stream_Digital DSD operates on 2.8, 5.6 or 11.2MHz sample rates and as a 1-bit stream. The two new types added by this patch describe streams that are capable of handling DSD samples in DOP format as 8-bit or in 16-bit (or at a x8 or x16 data rate, respectively). DSD itself specifies samples in *bit*, while DOP and ALSA handle them as *bytes*. Hence, a factor of 8 or 16 has to be applied for the sample rare configuration, according to the following table: configured hardware 176.4KHz 352.8kHz 705.6KHz <---- sample rate 8-bit 2.8MHz 5.6MHz 16-bit 2.8Mhz 5.6MHz 11.2MHz `-----------------------------' actual DSD sample rates Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

* ALSA: pcm: Add snd_pcm_rate_bit_to_rate()Dimitris Papastamos2012-06-181-0/+18
| | | | | | | | | | | This is essentially the reverse of snd_pcm_rate_to_rate_bit(). This is generally useful as the Compress API uses the rate bit directly and it helps to be able to map back to the actual sample rate.

* sound: Add export.h for THIS_MODULE/EXPORT_SYMBOL where neededPaul Gortmaker2011-11-011-0/+1
| | | | | | | | These aren't modules, but they do make use of these macros, so they will need export.h to get that definition. Previously, they got it via the implicit module.h inclusion. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

* [ALSA] Remove sound/driver.hTakashi Iwai2008-01-311-1/+0Star
| | | | | | | | | | | | This header file exists only for some hacks to adapt alsa-driver tree. It's useless for building in the kernel. Let's move a few lines in it to sound/core.h and remove it. With this patch, sound/driver.h isn't removed but has just a single compile warning to include it. This should be really killed in future.

* Linux-2.6.12-rc2Linus Torvalds2005-04-171-0/+481
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
