Re: [alsa-devel] [Question][ASoC][Topology] Question about ASoC Topology
by Mengdong Lin 20 Jul '16

20 Jul '16

Hi Takashi, Thanks for your explanation on how topology works! I cc the ML since potential users may also benefit from this info. Hi Lee, Now Intel SKL (Skylake) audio driver is using topology, which might be a reference for you. For the text conf file in user space, please see alsa-lib/src/conf/topology/sklrt286/skl_i2s.conf. The topology user space tool alsatplg will generate the SKL topology binary file for kernel. The doxygen doc also introduces the syntax. Besides the text conf file, you may also define topology objects by C API, declared in alsa-lib/include/topology.h For how the SKL platform driver loads the toplogy binary file, please see the kernel src code: sound/soc/intel/skylake/skl-topology.c, where snd_soc_tplg_component_load() is called to load the topology info and trigger ops binding in kernel. Now the upstreamed topology code support: controls, widgets, routes and PCM (Front-ends DAI & DAI links). And now we're upstreaming support for Back-end DAIs and BE links. This may be bring some ABI update and last for several weeks. You may try using topology atm, but you'll need to rebuild your topology binary info after the ABI update. I'll keep you updated when it's done. If you have any further questions, please let us know.

[alsa-devel] Alsa Soc details
by Chemsi Mehdi 19 Jul '16

19 Jul '16

Dear expert, I have some ALSA questions please: - Why codec driver of ASOC are always I2C based ?, is codec driver role is only control of audio hardware(set/reset registers only)? - There should be three drivers : machine driver, platform driver and codec driver , all of them have .probe and . remove , what is relation between all the probes? removes ? - As far I know McBSP is source of audio coming from host and I2C/ McBSP have no direct relation so why we connect platform driver (McBSP) with codec driver(I2C) Via DAI ? - When calling snd_pcm_open from userspace which kernel API is called ? snd_pcm_lib_ioctl or snd_stm_spdif_player_open ? if snd_stm_spdif_player_open so when called snd_pcm_lib_ioctl ? - How ALSA KERNELAPI is connected to ALSA SOC CORE, via which calls/mechanism ? Thanks q lot for your great help LINI

[alsa-devel] [PATCH v2] ALSA: echoaudio: purge contradictions between dimension matrix members and total number of members
by Takashi Sakamoto 17 Jul '16

17 Jul '16

Currently, sound device drivers for PCI cards produced by Echo Audio support dimension parameter of element information. But the information has contradictions to the number of members of each element. I guess that this comes from the assumption that these sound cards are used only by 'echomixer' in userspace. But ideally, they should be used with usual ALSA control applications. This commit removes the contradiction. As a result, 'Monitor Mixer Volume' and 'VMixer Volume' elements are shown in usual ALSA control applications such as 'amixer' and 'alsamixer' in series.

[alsa-devel] [alsa-lib][PATCH] ctl: rename APIs to add an element set so that their names are appropriate
by Takashi Sakamoto 17 Jul '16

In this development period, some APIs have already been added. Most of them are to add an element set, while their names are not so appropriate against their feature. This is due to following to names of old APIs. This commit renames them.

[alsa-devel] [PATCH v3 0/2] ASoC: add driver for Atmel I2S controller
by Cyrille Pitchen 17 Jul '16

17 Jul '16

This series of patches adds support to the new Atmel I2S controller embedded on sama5d2 SoCs. ChangeLog v2 -> v3 - fix the coding style, add some more comments and add a section dedicated to sama5d2 SoCs in the DT binding documentation as suggested by Mark Brown. v1 -> v2 - initialize dev->dev before calling dev->caps->mck_init() Cyrille Pitchen (2): ASoC: atmel-i2s: add DT bindings for I2S controller ASoC: atmel-i2s: add driver for the new Atmel I2S controller .../devicetree/bindings/sound/atmel-i2s.txt | 87 +++ sound/soc/atmel/Kconfig | 9 + sound/soc/atmel/Makefile | 2 + sound/soc/atmel/atmel-i2s.c | 770 +++++++++++++++++++++ 4 files changed, 868 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/atmel-i2s.txt create mode 100644 sound/soc/atmel/atmel-i2s.c -- 1.8.2.2
