[alsa-devel] [PATCH v2 00/20] ASoC: omap: Bind the omap-pcm platform driver to dai device
by Peter Ujfalusi 22 Apr '14

22 Apr '14

Hi, Changes since v1: - Add resource managed snd_soc_register_platform() - Use snd_soc_dai_init_dma_data() - omap-pcm is using the devm_snd_soc_register_platform() - Patch for davinci-mcasp since Version4 is using omap-pcm Cover letter from v1: This should have been done a long time ago... Add support for binding the omap-pcm platform to a dai device. IN this way we can remove the 'omap-pcm-audio' platform device/driver need. The change will also going to simplify cases when we boot with DT and we can use the same node for cpu_dai and platform.

[alsa-devel] sound disappears or noise heard after long run
by narayanan best 22 Apr '14

22 Apr '14

Hi, I am facing issue with alsa similar to the issue reported here http://mailman.alsa-project.org/pipermail/alsa-devel/2007-June/001726.html This is seen with latest alsa library and driver. Alsa is configured at 44100 (alsa.conf) and application plays at the rate of 48000. When the pointers cross the boundary value (after 6-7hrs), a continuous noise (jack hammer noise) or silence is heard. Issuing SIGSTOP and SIGCONT recovers the application and it starts playing normally. Pulseaudio is not running in our setup. It could be problem with calculation in the rate plugin. Let me know if you need further details.

[alsa-devel] [PATCHv4 2/2] ALSA: hda - Add driver for Tegra SoC HDA
by Dylan Reid 22 Apr '14

22 Apr '14

This adds a driver for the HDA block in Tegra SoCs. The HDA bus is used to communicate with the HDMI codec on Tegra124. Most of the code is re-used from the Intel/PCI HDA driver. It brings over only two of the module params, power_save and probe_mask. Signed-off-by: Dylan Reid <dgreid(a)chromium.org> --- Changes since v3: Remove some runtime-pm only code from the regular pm path. --- Changes since v2: Remove runtime PM. The on-chip codec doesn't support D3 stop clock so the pm_runtime code was never run. --- Changes since v1: Kconfig depends on OF and ARCH_TEGRA. Fix warning on 64 bit build. Integrate a bunch of good suggestions from Thierry, including: Add resets property to device tree entry. More consistent/better naming. Remove probe mask that isn't needed. Cleaner/more readable handling of dword write restriction. --- .../bindings/sound/nvidia,tegra30-hda.txt | 27 + sound/pci/hda/Kconfig | 15 + sound/pci/hda/Makefile | 2 + sound/pci/hda/hda_tegra.c | 585 +++++++++++++++++++++ 4 files changed, 629 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/nvidia,tegra30-hda.txt create mode 100644 sound/pci/hda/hda_tegra.c diff --git a/Documentation/devicetree/bindings/sound/nvidia,tegra30-hda.txt b/Documentation/devicetree/bindings/sound/nvidia,tegra30-hda.txt new file mode 100644 index 0000000..97f6832 --- /dev/null +++ b/Documentation/devicetree/bindings/sound/nvidia,tegra30-hda.txt @@ -0,0 +1,27 @@ +NVIDIA Tegra30 HDA controller + +Required properties: +- compatible : "nvidia,tegra30-hda" +- reg : Should contain the HDA registers location and length. +- interrupts : The interrupt from the hda controller. +- clocks : Must contain an entry for each required entry in clock-names. +- clock-names : Must include the following entries: hda, hdacodec_2x, hda2hdmi +- resets : Must contain an entry for each entry in reset-names. + See ../reset/reset.txt for details. +- reset-names : Must include the following entries: hda, hdacodec_2x, hda2hdmi + +Example: + +hda@70030000 { + compatible = "nvidia,tegra124-hda", "nvidia,tegra30-hda"; + reg = <0x0 0x70030000 0x10000>; + interrupts = <GIC_SPI 81 IRQ_TYPE_LEVEL_HIGH>; + clocks = <&tegra_car TEGRA124_CLK_HDA>, + <&tegra_car TEGRA124_CLK_HDA2HDMI>, + <&tegra_car TEGRA124_CLK_HDA2CODEC_2X>; + clock-names = "hda", "hda2hdmi", "hdacodec_2x"; + resets = <&tegra_car 125>, /* hda */ + <&tegra_car 128>; /* hda2hdmi */ + <&tegra_car 111>, /* hda2codec_2x */ + reset-names = "hda", "hda2hdmi", "hdacodec_2x"; +}; diff --git a/sound/pci/hda/Kconfig b/sound/pci/hda/Kconfig index ac17c3f..f17c016 100644 --- a/sound/pci/hda/Kconfig +++ b/sound/pci/hda/Kconfig @@ -20,6 +20,21 @@ config SND_HDA_INTEL To compile this driver as a module, choose M here: the module will be called snd-hda-intel. +config SND_HDA_TEGRA + tristate "NVIDIA Tegra HD Audio" + depends on OF && ARCH_TEGRA + select SND_HDA + help + Say Y here to support the HDA controller present in NVIDIA + Tegra SoCs + + This options enables support for the HD Audio controller + present in some NVIDIA Tegra SoCs, used to communicate audio + to the HDMI output. + + To compile this driver as a module, choose M here: the module + will be called snd-hda-tegra. + if SND_HDA config SND_HDA_DSP_LOADER diff --git a/sound/pci/hda/Makefile b/sound/pci/hda/Makefile index d0d0c19..194f3093 100644 --- a/sound/pci/hda/Makefile +++ b/sound/pci/hda/Makefile @@ -1,5 +1,6 @@ snd-hda-intel-objs := hda_intel.o snd-hda-controller-objs := hda_controller.o +snd-hda-tegra-objs := hda_tegra.o # for haswell power well snd-hda-intel-$(CONFIG_SND_HDA_I915) += hda_i915.o @@ -47,3 +48,4 @@ obj-$(CONFIG_SND_HDA_CODEC_HDMI) += snd-hda-codec-hdmi.o # otherwise the codec patches won't be hooked before the PCI probe # when built in kernel obj-$(CONFIG_SND_HDA_INTEL) += snd-hda-intel.o +obj-$(CONFIG_SND_HDA_TEGRA) += snd-hda-tegra.o diff --git a/sound/pci/hda/hda_tegra.c b/sound/pci/hda/hda_tegra.c new file mode 100644 index 0000000..afdf5e1 --- /dev/null +++ b/sound/pci/hda/hda_tegra.c @@ -0,0 +1,585 @@ +/* + * + * Implementation of primary alsa driver code base for NVIDIA Tegra HDA. + * + * This program is free software; you can redistribute it and/or modify it + * under the terms and conditions of the GNU General Public License, + * version 2, as published by the Free Software Foundation. + * + * This program is distributed in the hope it will be useful, but WITHOUT + * ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or + * FITNESS FOR A PARTICULAR PURPOSE.

[alsa-devel] How to create a proc entry for an ASoc codec?
by Lin, Mengdong 22 Apr '14

22 Apr '14

Hi, How to create a proc entry for an ASoc codec under the sound card? We hope to create an proc entry for an I2S codec under /proc/asound/cardx, to debug the codec status at runtime. So after the machine driver calls snd_soc_register_card(&soc_card), I calls snd_card_proc_new(soc_card .snd_card, ....) But no codec entry is created although dmesg shows this function succeeds. How ASoC creates the proc entries such as 'id' for the sound card? Thanks Mengdong

[alsa-devel] [PATCH 0/7] ASoC: Move IO and kcontrols to the component level
by Lars-Peter Clausen 21 Apr '14

21 Apr '14

This series contains the remaining patches from the previous series that have not been applied yet. The series has been rebased ontop of asoc/for-next and depends on topic/sta350, topic/core, topic/dapm, topic/cache and topic/component. Some minor updates were made to the patches and three new patches: * One new user of snd_kcontrol_chip() showed up, the patch converts it to snd_soc_kcontrol_codec() * Change return type of snd_soc_write() from unsigned int to int * Remove ASoC level tracing Original cover letter: This series is the first step towards full componentisation of the ASoC core. It moves both the IO abstraction layers within ASoC as well as the standard set of kcontrols to the component level. This for example means we can get rid of constructs like if (w->codec) snd_soc_read(....) else if(w->platform) snd_soc_platform_read(...) Moving the kcontrols to the component level means we can use the same implementation also for other non-CODEC components. E.g. there seems to be an increasing amount of CPU components that have basic signal processing and things like volume controls etc. whose register layout is similar to those used in CODECs. Currently each CPU component driver re-implements these controls by hand. The first two patches introduce two new helper functions which hide the actual implementation on how the CODEC or platform struct that register a control can be obtained from the control. This means that when the actual implementation is changed only the two helper functions need to be updated and not every single driver. The patches that follow that are just cleanups removing unused IO stuff and move all IO functions to soc-io.c. The next step is to make platforms also components. And then finally first the IO abstraction layers in ASoC are unified at the component level and then on top of that the kcontrol helpers are moved to the component level. The series depends on quite a few topic branches related to changes to the core and cleanups for individual drivers. It is probably best to place it on top of asoc-v3.15-2. The patch that moves the kcontrols to the component level also has a runtime dependency on the not yet applied patches that move the ams-delta and mfld_machine controls to the card level. - Lars Lars-Peter Clausen (7): ASoC: sta350: Use snd_soc_kcontrol_codec() ASoC: Change return type of snd_soc_write() to int ASoC: Move IO abstraction to the component level ASoC: Move standard kcontrol helpers to the component level ASoC: Remove snd_soc_update_bits_locked() ASoC: dapm: Rename soc_widget_update_bits_locked() to soc_widget_update_bits() ASoC: Remove ASoC level IO tracing include/sound/soc-dapm.h | 1 + include/sound/soc.h | 55 ++++++-- include/trace/events/asoc.h | 92 ------------- sound/soc/codecs/sta350.c | 4 +- sound/soc/soc-core.c | 284 +++++++++++++++++++++++++------------- sound/soc/soc-dapm.c | 91 ++---------- sound/soc/soc-io.c | 327 ++++++++++++++++++++++++++------------------ 7 files changed, 450 insertions(+), 404 deletions(-) -- 1.8.0

[alsa-devel] [dapm question] About "playback_widget" power on or not
by 胡洪兵 21 Apr '14

21 Apr '14

hi dapm developers, I have a question about "playback_widget". Nobody gives me right answer, so email the question to devel maillist. I am sorry to disturb you and thanks for your explain Question: my machine driver export two pcm devices, eg. "pcm0", "pcm1". Open the "pcm0" for Playback, just active AIF3 playback_widget "AIF3 Playbck". at same time，one path of pcm1 is also power on。 the path is “Headset Mic -> IN3R -> AIF1TX Input 1 -> AIF1TX Mixer -> AIF1TX -> AIF1 Playbck -> AIF1RX1 -> Headphone Input 1 -> Headphone Mixer -> Headphone” my question is "the widgets of the path should be powered or not ?" I guess that the path should not be powered, because "pcm1" is not open, all paths of it should not be actvie. Maybe I am wrong， but let me known. Thank you very much! ***************************************************************case snd_soc_dapm_dai_in: w->power_check = dapm_dac_check_power; /* Check to see if a DAC has power */static int dapm_dac_check_power(struct snd_soc_dapm_widget *w){ int out; DAPM_UPDATE_STAT(w, power_checks); if (w->active) { out = is_connected_output_ep(w, NULL); dapm_clear_walk_output(w->dapm, &w->sinks); return out != 0; } else { return dapm_generic_check_power(w); }} ***************************************************************

[alsa-devel] alsa-utils aplay/arecord can't be interrupted when streaming is not active
by jiwang 21 Apr '14

21 Apr '14

Hi All With latest 1.0.27.2 alsa-utils, I am facing problem to interrupt aplay/arecord when the streaming is not active (no data can be written to or read from cards) further more, if I start aplay/arecord with "-N" nonblocking option, then aplay/arecord can never exit, unless I do a system reset I found if I revert the following patch /commit 1d0042d7e948815f8015c62bc53143eed3b83206// //Author: Jaroslav Kysela <perex(a)perex.cz>// //Date: Mon Apr 8 13:30:54 2013 +0200// // // aplay/arecord: change the interrupt handling using snd_pcm_abort()// //// // It is required (exclude the fatal SIGABRT) to call snd_pcm_close() and// // the end of work (outside of the interrupt handler). Use new snd_pcm_abort()// // function to inform alsa-lib to not ignore EINTR and move the in_aborting// // variable to the global scope to be checked in the i/o loops.// //// // Signed-off-by: Jaroslav Kysela <perex(a)perex.cz>// / http://git.alsa-project.org/?p=alsa-utils.git;a=commit;h=1d0042d7e948815f80… then aplay/arecord can be interrupted correctly Is it a defect in aplay.c or did I miss something? Thanks, Jiada
