[alsa-devel] How to transfer data to the endpoint (e.g. .wav file) in alsa external I/O plugin
by Hermes Zhang 08 Nov '16

08 Nov '16

Hi, I'm a new in alsa plugin develop. Now I'm try to implement an I/O plugin for my platform in alsa. I can config the alsa plugin and start it, but when I'm deal with the data in the transfer api, I could not flush the data to the endpoint, e.g. .wav file. I run below command to test my plugin: arecord -D my_plug -c 1 -f S16_LE raw I want to save the audio data to a wav file by my plugin. Then in my code, I try to write the data to the area structure like this: static snd_pcm_sframes_t my_read (snd_pcm_ioplug_t * io, const snd_pcm_channel_area_t * areas, snd_pcm_uframes_t offset, snd_pcm_uframes_t size) { /* I got the audio data from other api here */ memcpy(areas->addr + areas->first + areas->step * offset, my_data, size); } But I could not get a correct wav file, there will be a file named "raw" but only with some wav file head, not real data include. Does anyone know anything I'm wrong? Is this the right way to handle the transfer data? Thanks. Best Regards, Hermes

[alsa-devel] Use of snd_atomic_write_t for dshare and friends
by Alan Young 08 Nov '16

08 Nov '16

Would it make sense for dshare, and other d-* plugins, to use a shared snd_atomic_write_t in the shared memory segment and associated snd_atomic_write_xxx() & snd_atomic_read_xxx() calls?

[alsa-devel] [PATCH 0/2] Harden proc interface
by Takashi Iwai 08 Nov '16

08 Nov '16

Hi, here is a small patch series to harden the accesses to ALSA proc files. Both are marked with v4.2+ stable, just because they are cleanly applicable since that version due to the code rewrite at 4.2.

[alsa-devel] [PATCH v3] drm: bridge: add DesignWare HDMI I2S audio support
by Kuninori Morimoto 08 Nov '16

08 Nov '16

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> Current dw-hdmi is supporting sound via AHB bus, but it has I2S audio feature too. This patch adds I2S audio support to dw-hdmi. This HDMI I2S is supported by using ALSA SoC common HDMI encoder driver.

Re: [alsa-devel] Imx6 i2s master driver without i2c
by Bode, Michael (PED-DEAS) 07 Nov '16

Hi, I know, it's some time ago since there was this discussion ongoing. I don't know if you already solved your problems. Because I had a similar task to solve I maybe have some information that could help here: In my case calling function "snd_soc_dai_set_pll(cpu_dai, 0, 0, 688128000, itel_audio_fmts[i].sysclk);" was not working. When looking into the details I found that underlying Driver (in my case fsl_ssi.c) had not implemented function "set_pll", so calling this function was just a dummy. Then I tried to figure out how to manipulate the Audio PLL in i.MX6 and Found the file "clk-imx6q.c" which sets all clocks of i.MX6. To register a clock the function clk_register_clkdev needs to be called for that clock. Now I found that this registration was missing for PLL4 which in my case should be used for audio. So I added "clk_register_clkdev(clk[IMX6QDL_CLK_PLL4_AUDIO_DIV], "pll4", NULL);". With this change I was able to call "pll4 = clk_get(NULL, "pll4");" from my SOC-driver and do a pllRate = clk_round_rate(pll4, 688128000); and clk_set_rate(pll4, pllRate); Finally with this I was able to change Audio PLL according to sample rate to get proper SSI signals. A second thing I found in your chat was that you had the problem that no matter what sample frequency you use, you always get 44100. I also ran into that issue and found that there is an ALSA feature active That intentionally converts the audio rate. I found the config file asound.conf in /etc that defines: pcm.dmix_44100{ type dmix ipc_key 5678293 ipc_key_add_uid yes slave{ pcm "hw:0,0" period_time 40000 buffer_time 360000 format S16_LE rate 44100 } } pcm.asymed{ type asym playback.pcm "dmix_44100" capture.pcm "dsnoop_44100" } As a result all my frequencies were intentionally converted to 44100 Hz. So my solution was to just rename/delete asound.conf I hope this can help others to get an i.MX I2S Master running. Best regards, Michael Bode

[alsa-devel] Locking/mutex for snd_pcm_update_hw_ptr0() call
by Alan Young 07 Nov '16

07 Nov '16

As far as I can see, snd_pcm_update_hw_ptr0() is a critical section of code that is protected by some form of mutex in all its call paths: snd_pcm_period_elapsed() - snd_pcm_stream_lock_irqsave() snd_pcm_update_hw_ptr() snd_pcm_lib_ioctl_reset() - snd_pcm_stream_lock_irqsave() snd_pcm_lib_write1() - snd_pcm_stream_lock_irq() snd_pcm_lib_read1() - snd_pcm_stream_lock_irq() snd_pcm_status() - snd_pcm_stream_lock_irq() snd_pcm_do_pause - I think via the locking in snd_pcm_action() snd_pcm_playback_rewind() - snd_pcm_stream_lock_irq() snd_pcm_capture_rewind() - snd_pcm_stream_lock_irq() snd_pcm_playback_forward() - snd_pcm_stream_lock_irq() snd_pcm_capture_forward() - snd_pcm_stream_lock_irq() snd_pcm_hwsync() - snd_pcm_stream_lock_irq() snd_pcm_delay() - snd_pcm_stream_lock_irq() However, I am not familiar with how kernel locking mechanisms work. It is possible that the DMA interrupt handler (snd_pcm_period_elapsed()), could call snd_pcm_update_hw_ptr0() while it is part way through a call from snd_pcm_status(), or vice versa? Alan.

[alsa-devel] [PATCH v4 0/3] ASoC/ARM: tegra: apalis t30/tk1/colibri t30: sgtl5000 audio
by Marcel Ziswiler 07 Nov '16

07 Nov '16

This series adds/integrates Freescale SGTL5000 analogue audio codec support. Changes in v4: - simple-audio-card does still not allow for more advanced use cases like Tegra SoCs - further platform drivers have been accepted since my last attempt (e.g. rt5677 one) - relevance for one further board the new Toradex Apalis TK1 - drop unused sound/jack.h include - in tegra_sgtl5000_driver_remove() pass return value of snd_soc_unregister_card() on to caller - no longer set owner property in platform_driver to THIS_MODULE - re-based/resend Changes in v3: - revert to not using simple-audio-card being incompatible with tegra - rebased to for-next Changes in v2: - using simple-audio-card as suggested by Fabio Marcel Ziswiler (3): ASoC: tegra: add tegra sgtl5000 machine driver ARM: tegra: apalis/colibri t30: integrate audio ARM: tegra: enable sgtl5000 audio .../bindings/sound/nvidia,tegra-audio-sgtl5000.txt | 42 ++++ arch/arm/boot/dts/tegra30-apalis.dtsi | 49 +++++ arch/arm/boot/dts/tegra30-colibri.dtsi | 49 +++++ arch/arm/configs/tegra_defconfig | 1 + sound/soc/tegra/Kconfig | 11 ++ sound/soc/tegra/Makefile | 2 + sound/soc/tegra/tegra_sgtl5000.c | 212 +++++++++++++++++++++ 7 files changed, 366 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/nvidia,tegra-audio-sgtl5000.txt create mode 100644 sound/soc/tegra/tegra_sgtl5000.c -- 2.5.5
