[alsa-devel] Segmentation Fault in snd_pcm_rate_hw_free()

Hi, I was reproducing the crash that Valentin Corfu reported earlier with his test. Valgrind and gdb show that expand_linear_s16() is somehow corrupting the area used for memory management by libc for rate->pareas[0].addr More exactly, the line that seems to corrupt the heap in static void expand_linear_s16() is: *dst = (old_sample * old_weight + new_sample * new_weight) >> 16; As Valgrind says: ==11161== Invalid write of size 2 ==11161== at 0x40A8A82: linear_expand_s16 (pcm_rate_linear.c:179) ==11161== by 0x40A85A9: linear_convert (pcm_rate_linear.c:320) ==11161== by 0x40A6915: do_convert (pcm_rate.c:537) ==11161== by 0x40A6C7D: snd_pcm_rate_write_areas1 (pcm_rate.c:550) ==11161== by 0x40A6C7D: snd_pcm_rate_commit_area (pcm_rate.c:749) ==11161== by 0x40A7014: snd_pcm_rate_drain (pcm_rate.c:1105) ==11161== by 0x4084511: snd_pcm_drain (pcm.c:1122) ==11161== by 0x8049288: main (in /root/pcm_min_daisuke) ==11161== Address 0x43d6258 is 0 bytes after a block of size 86,016 alloc'd ==11161== at 0x40261B1: malloc (in /usr/lib/valgrind/vgpreload_memcheck-x86-linux.so) ==11161== by 0x4099801: snd_pcm_mmap (pcm_mmap.c:425) ==11161== by 0x4093CA7: sndrv_pcm_hw_params (pcm_params.c:2366) ==11161== by 0x409A59C: snd1_pcm_generic_hw_params (pcm_generic.c:104) ==11161== by 0x4091E7F: snd1_pcm_hw_params_slave (pcm_params.c:2250) ==11161== by 0x40A54AC: snd_pcm_rate_hw_params (pcm_rate.c:246) ==11161== by 0x4093AE3: sndrv_pcm_hw_params (pcm_params.c:2326) ==11161== by 0x40ABC37: snd_pcm_plug_hw_params (pcm_plug.c:1045) ==11161== by 0x4093AE3: sndrv_pcm_hw_params (pcm_params.c:2326) ==11161== by 0x4084281: snd_pcm_hw_params (pcm.c:830) ==11161== by 0x8048F84: main (in /root/pcm_min_daisuke) ==11161== ==11161== Invalid free() / delete / delete[] / realloc() ==11161== at 0x402726D: free (in /usr/lib/valgrind/vgpreload_memcheck-x86-linux.so) ==11161== by 0x40A53C0: snd_pcm_rate_hw_free (pcm_rate.c:344) ==11161== by 0x4083CDA: snd_pcm_hw_free (pcm.c:853) ==11161== by 0x40A9E8D: snd_pcm_plug_hw_free (pcm_plug.c:1061) ==11161== by 0x4083CDA: snd_pcm_hw_free (pcm.c:853) ==11161== by 0x80492AC: main (in /root/pcm_min_daisuke) ==11161== Address 0xe705004b is not stack'd, malloc'd or (recently) free'd I'm not very familiar with alsa in general and was wondering if someone who knows more on it can drop a look on this one?

[alsa-devel] [PATCH] ASoC: topology: Add Kconfig option for topology
by Mark Brown 18 Aug '15

18 Aug '15

Allow the topology code to be compiled out so that users who don't need topology don't need to havve the code compiled in, saving them some memory. Some more configuration could be added to remove some of the hooks into the core data structures but that is probably best done with some refactoring to use functions to do the updates of the data structures rather than ifdefing in the code as we'd need to do at the minute.

[alsa-devel] [PATCH v2 00/10] ASoC: support adding PCM dynamically from topology
by mengdong.lin＠intel.com 18 Aug '15

18 Aug '15

From: Mengdong Lin <mengdong.lin(a)intel.com> This series allows the topology core to create PCM devices dynamically. The user can define different DAIs in the topology files for different versions of firmware, but share a generic platform and machine driver. A dummy DAI and DAI link can be used to register the soc card and specify the platform with topology. Then real DAIs are created in platform probing phase by the topology core, and the machine driver will be notified to create relavant DAI links. We tested using topology to create FE DAI/DAI links on Broadwell. Mengdong Lin (10): ASoC: Change the PCM runtime array to a list ASoC: Define soc_init_dai_link() to wrap link intialization. ASoC: Change 2nd argument of soc_bind_dai_link() to DAI link pointer ASoC: Implement DAI links in a list ASoC: Add support for dummy DAI links and PCM runtimes ASoC: Bind new DAI links after probing components ASoC: Support adding a DAI dynamically ASoC: topology: Change pass number of DAI smaller than graph ASoC: topology: Change stream formats to bitwise flag ASOC: topology: Add PCM DAIs dynamically when loading them include/sound/soc-dai.h | 1 + include/sound/soc-topology.h | 1 - include/sound/soc.h | 28 +- include/uapi/sound/asoc.h | 2 +- sound/soc/fsl/fsl-asoc-card.c | 10 +- sound/soc/fsl/imx-wm8962.c | 10 +- sound/soc/generic/simple-card.c | 12 +- sound/soc/intel/atom/sst-mfld-platform-pcm.c | 12 +- sound/soc/intel/boards/cht_bsw_rt5645.c | 7 +- sound/soc/intel/boards/cht_bsw_rt5672.c | 7 +- sound/soc/pxa/mioa701_wm9713.c | 6 +- sound/soc/samsung/bells.c | 40 +- sound/soc/samsung/littlemill.c | 32 +- sound/soc/samsung/odroidx2_max98090.c | 9 +- sound/soc/samsung/snow.c | 9 +- sound/soc/samsung/speyside.c | 12 +- sound/soc/samsung/tobermory.c | 21 +- sound/soc/soc-core.c | 642 +++++++++++++++++++-------- sound/soc/soc-dapm.c | 7 +- sound/soc/soc-pcm.c | 22 +- sound/soc/soc-topology.c | 99 ++++- sound/soc/tegra/tegra_wm8903.c | 3 +- 22 files changed, 701 insertions(+), 291 deletions(-) -- 1.9.1

[alsa-devel] [PATCH] ASoC: mediatek: Remove AIF widgets for backend DAIs
by Koro Chen 17 Aug '15

17 Aug '15

DAPM core already creates widgets for DAIs. It is not necessary to declare them by SND_SOC_DAPM_AIF_IN/SND_SOC_DAPM_AIF_OUT. Furthermore, original codes use backend DAI's stream name to be the AIF widget name. It causes the same widget to be created twice, and after commit 92fa12426741 ("ASoC: dapm: Add new widgets to the end of the widget list") the first created widget (by snd_soc_dapm_new_controls) is used, not the 2nd created one (by snd_soc_dapm_new_dai_widgets), so audio path is broken.

[alsa-devel] [PATCH RFC v3 0/7] Implement generic ASoC HDMI codec and use it in tda998x
by Jyri Sarha 17 Aug '15

17 Aug '15

This is my third RFC patch series on the subject. This time also the tda998x driver patches are a serious attempt to come up with an initial implementation for HDMI audio ASoC support. Russell's "drm/edid: add function to help find SADs" is here just to produce a working patch-set on top of mainline. It should be getting in trough drm-next at some point. The binding for tda998x is taken from Jean Francois' patch series[1] on the same subject. The implementation of the of-node parsing has some minor changes from my self. Here is what I think at least could or should still be done, but non of that stuff does not sounds critical right now. Missing from tda998x driver side - hdmi_codec_ops audio_startup() implementation for audio abort support - multi channel audio support (I would need specs and preferably some HW to test for this). Missing from ASoC side generic implementation: - channel_allocation handling is completely left for the video side driver, see if ASoC side could help in any way - snd_soc_jack functionality to handle hdmi cable plug/unplug events [1] http://mailman.alsa-project.org/pipermail/alsa-devel/2015-July/095596.html Best regards, Jyri Jean-Francois Moine (1): drm/i2c: tda998x: Add support of a DT graph of ports Jyri Sarha (5): ASoC: hdmi: Remove obsolete dummy HDMI codec ASoC: hdmi-codec: Add hdmi-codec for external HDMI-encoders drm/i2c: tda998x: Remove include/sound/tda998x.h and fix graph parsing drm/i2c: tda998x: Register ASoC HDMI codec for audio functionality ARM: dts: am335x-boneblack: Add HDMI audio support Russell King - ARM Linux (1): drm/edid: add function to help find SADs, DO NOT MERGE .../devicetree/bindings/drm/i2c/tda998x.txt | 51 +++ arch/arm/boot/dts/am335x-boneblack.dts | 90 +++- drivers/gpu/drm/i2c/Kconfig | 1 + drivers/gpu/drm/i2c/tda998x_drv.c | 336 +++++++++++++-- include/drm/drm_edid.h | 19 + include/sound/hdmi-codec.h | 99 +++++ sound/soc/codecs/Kconfig | 3 +- sound/soc/codecs/Makefile | 4 +- sound/soc/codecs/hdmi-codec.c | 467 +++++++++++++++++++++ sound/soc/codecs/hdmi.c | 109 ----- 10 files changed, 1026 insertions(+), 153 deletions(-) create mode 100644 include/sound/hdmi-codec.h create mode 100644 sound/soc/codecs/hdmi-codec.c delete mode 100644 sound/soc/codecs/hdmi.c -- 1.9.1

V2: Update after comments from Lars-Peter yesterday: set rate to CONTINUOUS and let ALSA figure out the details, also removing hw_params as it is then not needed. Add support for the InvenSense ICS-43432 I2S MEMS microphone. This is a non-software-configurable MEMS microphone with I2S output.
