2020-03-16ALSA: compress: add alac & ape decoder paramsVinod Koul1-1/+25
Add ALAC (Apple Lossless Audio Codec) and APE (Monkey's Lossless Audio Codec) defines and parameters required to configure these.

2020-03-16ALSA: compress: Add wma decoder paramsVinod Koul1-0/+8
Some WMA decoders like WMAv10 etc need some additional encoder option parameters, so add these as WMA decoder params.

Some codec profiles were missing for WMA, like WMA9/10 lossless and wma10 pro, so add these profiles Signed-off-by: Vinod Koul <vkoul@kernel.org> Reviewed-by: Takashi Iwai <tiwai@suse.de> Link: https://lore.kernel.org/r/20200316055221.1944464-2-vkoul@kernel.org Signed-off-by: Mark Brown <broonie@kernel.org>
2019-11-18ALSA: compress: add flac decoder paramsVinod Koul1-0/+10
The current design of sending codec parameters assumes that decoders will have parsers so they can parse the encoded stream for parameters and configure the decoder. But this assumption may not be universally true and we know some DSPs which do not contain the parsers so additional parameters are required to be passed. So add these parameters starting with FLAC decoder. The size of snd_codec_options is still 120 bytes after this change (due to this being a union) Co-developed-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Signed-off-by: Vinod Koul <vkoul@kernel.org> Link: https://lore.kernel.org/r/20191115102705.649976-2-vkoul@kernel.org Acked-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2017-11-02License cleanup: add SPDX license identifier to uapi header files with a licenseGreg Kroah-Hartman1-0/+1
Many user space API headers have licensing information, which is either incomplete, badly formatted or just a shorthand for referring to the license under which the file is supposed to be. This makes it hard for compliance tools to determine the correct license. Update these files with an SPDX license identifier. The identifier was chosen based on the license information in the file. GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license identifier with the added 'WITH Linux-syscall-note' exception, which is the officially assigned exception identifier for the kernel syscall exception: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". This exception makes it possible to include GPL headers into non GPL code, without confusing license compliance tools. Headers which have either explicit dual licensing or are just licensed under a non GPL license are updated with the corresponding SPDX identifier and the GPLv2 with syscall exception identifier. The format is: ((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE) SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. The update does not remove existing license information as this has to be done on a case by case basis and the copyright holders might have to be consulted. This will happen in a separate step. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

2015-12-23ALSA: compress: Add SND_AUDIOCODEC_BESPOKECharles Keepax1-2/+3
When working with the compressed framework occasionally vendors will use esoteric internal audio formats. For such formats it doesn't really make sense to add an new define to the kernel as their use is not sufficiently general. This patch adds a new define SND_AUDIOCODEC_BESPOKE that vendors can use in such situations.

2014-06-23ALSA: compress: fix the struct alignment to 4 bytesVinod Koul1-7/+7
In 64bit systems the compiler can default align to 8bytes causing mis-match with 32bit usermode. Avoid this is future by ensuring all the structures shared with usermode are packed and aligned to 4 bytes irrespective of arch used [coding style fixes by tiwai] Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2014-01-05ALSA: compress: update struct snd_codec_desc for sample rateVinod Koul1-1/+2
Now that we don't use SNDRV_PCM_RATE_xxx bit fields for sample rate, we need to change the description to an array for describing the sample rates supported by the sink/source Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
