[alsa-devel] [PATCH v4] ASoC: Add MediaTek MT6660 Speaker Amp Driver
by Jeff Chang 09 Jan '20

09 Jan '20

From: Jeff Chang <jeff_chang(a)richtek.com> The MT6660 is a boosted BTL class-D amplifier with V/I sensing. A built-in DC-DC step-up converter is used to provide efficient power for class-D amplifier with multi-level class-G operation. The digital audio interface supports I2S, left-justified, right-justified, TDM and DSP A/B format for audio in with a data out used for chip information like voltage sense and current sense, which are able to be monitored via DATAO through proper Signed-off-by: Jeff Chang <jeff_chang(a)richtek.com> --- Documentation/devicetree/bindings/sound/mt6660.txt | 53 ++ sound/soc/codecs/Kconfig | 11 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/mt6660.c | 628 +++++++++++++++++++++ sound/soc/codecs/mt6660.h | 75 +++ 5 files changed, 769 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/mt6660.txt create mode 100644 sound/soc/codecs/mt6660.c create mode 100644 sound/soc/codecs/mt6660.h changelogs between v4 & v3 - remove unnecessary kcontrols. - modify copy right header. - use dev_dbg instead of dev_info. - add necessary debug message. - add DT binding documentation. - add space before } at every table. changelogs between v3 & v2 - modify MT6660 Kconfig, remove unnecessary selection. - remove my own debug io interface. use standard regmap for debugging. - remove regmap volatile ops, we do not use cache. - remove component io read/write function, use snd_soc_component_init_regmap. - remove init setting write code.

[alsa-devel] [PATCH for-5.6 0/2] drm/bridge: dw-hdmi: PCM API updates
by Takashi Iwai 09 Jan '20

09 Jan '20

Hi, this is a patch set for updating ALSA PCM API usages in dw-hdmi driver. I already tried to "fix" the driver some time ago but it was utterly wrong. So this is a combination of the revised patch and another cleanup patch. The first one is to change the buffer allocation mechanism in the driver to the manual allocation of the h/w buffer and the automatic allocation of PCM stream buffers via the new standard API. The significant change is that size of the h/w buffer isn't no longer controlled via ALSA preallocation proc file but rather via the new module option (if any). The second one is a oneliner patch just to remove the superfluous PCM ops. Both need the ALSA PCM core changes in 5.5-rc1, so please apply them on top of 5.5-rc1 or later. Or, just let me know if I should apply them through sound git tree. thanks, Takashi === Takashi Iwai (2): drm/bridge: dw-hdmi: Follow the standard ALSA memalloc way drm/bridge: dw-hdmi: Drop superfluous ioctl PCM ops .../gpu/drm/bridge/synopsys/dw-hdmi-ahb-audio.c | 49 ++++++++++++---------- 1 file changed, 26 insertions(+), 23 deletions(-) -- 2.16.4

[alsa-devel] Playback/Capture on a codec-to-codec link
by Gabriele Zampieri 09 Jan '20

09 Jan '20

Dear all, I'm working on a board that is equipped with a Bluetooth chip and a gsm phone, both connected to the CPU (AM3352) on 2 different pcm. I wrote the codecs and they are working (read as: I can play/record on both devices). What I want to achieve now is to route those pcm together and still being able to (at least) play audio on both. I tried alsaloop, but it eats too much CPU (80% +) even in half duplex loop (BT capture => GSM playback), and it was the only application running. In [1] I saw that I should be able to route the codec together in kernel space (to avoid data copy between user and kernel spaces). I did not tried that solution yet because it's not really clear to me how to implement it, any suggestions/examples? If I follow that solution, can I still use those PCM to playback my audio file (I see that I can disconnect that link through a mixer control, so this should be possible)? Again any suggestion is really appreciated. Best regards, Gabriele [1]: https://www.kernel.org/doc/html/latest/sound/soc/dpcm.html#hostless-pcm-str…

[alsa-devel] [PATCH] ALSA: hda: Rename back to dmic_detect option
by Takashi Iwai 09 Jan '20

09 Jan '20

We've got quite a few bug reports showing the SOF driver being loaded unintentionally recently, and the reason seems to be that users didn't know the module option change: with the recent kernel, a new option dsp_driver=1 has to be passed to a new module snd-intel-dspcfg instead of snd_hda_intel.dmic_detect=0 option. That is, actually there are two tricky things here: - We changed the whole detection in another module and another option semantics. - The existing option for skipping the DSP probe was also renamed. For avoiding the confusion and giving user more hint, this patch reverts the renamed option dsp_driver back to dmic_detect for snd-hda-intel module, and show the warning about the module option change when the non-default value is passed.

[alsa-devel] MIDI 2.0 packet interface impact on ALSA & Linux
by happy musicmaker 09 Jan '20

09 Jan '20

What is the impact assessment so far done for MIDI 2.0 for ALSA & Linux ? Will a kernel change be needed for (USB) MIDI to support the MIDI 2.0 packet interface ? How about the ALSA sequencer API ? Any activities around this ? MIDI application based on Jack MIDI impact ? https://www.midi.org/articles-old/details-about-midi-2-0-midi-ci-profiles-a… https://www.midi.org/articles-old/midi-2-0-scope https://thefeaturestory.com/2019/12/05/artlogic-give-exclusive-preview-of-m… https://www.namm.org/thenammshow/2020/events/a3e-workshop-art-logic-midi-20… https://juce.com/discover/stories/introducing-midi-2-0 https://www.musictech.net/features/midi-2-0-what-mean-for-you/

[alsa-devel] [PATCH] treewide: remove redundent IS_ERR() before error code check
by Masahiro Yamada 08 Jan '20

08 Jan '20

'PTR_ERR(p) == -E*' is a stronger condition than IS_ERR(p). Hence, IS_ERR(p) is unneeded. The semantic patch that generates this commit is as follows: // <smpl> @@ expression ptr; constant error_code; @@ -IS_ERR(ptr) && (PTR_ERR(ptr) == - error_code) +PTR_ERR(ptr) == - error_code // </smpl> Signed-off-by: Masahiro Yamada <masahiroy(a)kernel.org> --- crypto/af_alg.c | 2 +- drivers/acpi/scan.c | 2 +- drivers/char/hw_random/bcm2835-rng.c | 2 +- drivers/char/hw_random/omap-rng.c | 4 ++-- drivers/clk/clk.c | 2 +- drivers/dma/mv_xor_v2.c | 2 +- drivers/gpio/gpiolib-devres.c | 2 +- drivers/gpio/gpiolib-of.c | 8 ++++---- drivers/gpio/gpiolib.c | 2 +- drivers/i2c/busses/i2c-mv64xxx.c | 5 ++--- drivers/i2c/busses/i2c-synquacer.c | 2 +- drivers/mtd/ubi/build.c | 2 +- drivers/of/device.c | 2 +- drivers/pci/controller/pci-tegra.c | 2 +- drivers/phy/phy-core.c | 4 ++-- drivers/spi/spi-orion.c | 3 +-- drivers/video/fbdev/imxfb.c | 2 +- fs/ext4/super.c | 2 +- fs/f2fs/node.c | 2 +- fs/ocfs2/suballoc.c | 2 +- fs/sysfs/group.c | 2 +- net/core/dev.c | 2 +- net/core/filter.c | 2 +- net/xfrm/xfrm_policy.c | 2 +- sound/soc/codecs/ak4104.c | 3 +-- sound/soc/codecs/cs4270.c | 3 +-- sound/soc/codecs/tlv320aic32x4.c | 6 ++---- sound/soc/sunxi/sun4i-spdif.c | 2 +- 28 files changed, 35 insertions(+), 41 deletions(-) diff --git a/crypto/af_alg.c b/crypto/af_alg.c index 0dceaabc6321..0cc82bec0657 100644 --- a/crypto/af_alg.c +++ b/crypto/af_alg.c @@ -169,7 +169,7 @@ static int alg_bind(struct socket *sock, struct sockaddr *uaddr, int addr_len) sa->salg_name[sizeof(sa->salg_name) + addr_len - sizeof(*sa) - 1] = 0;

[alsa-devel] [PATCH] ALSA: hda: enable regmap internal locking
by Kai Vehmanen 08 Jan '20

This reverts commit 42ec336f1f9d ("ALSA: hda: Disable regmap internal locking"). Without regmap locking, there is a race between snd_hda_codec_amp_init() and PM callbacks issuing regcache_sync(). This was caught by following kernel warning trace: <4> [358.080081] WARNING: CPU: 2 PID: 4157 at drivers/base/regmap/regcache.c:498 regcache_cache_only+0xf5/0x130 [...] <4> [358.080148] Call Trace: <4> [358.080158] snd_hda_codec_amp_init+0x4e/0x100 [snd_hda_codec] <4> [358.080169] snd_hda_codec_amp_init_stereo+0x40/0x80 [snd_hda_codec] Suggested-by: Takashi Iwai <tiwai(a)suse.de> BugLink: https://gitlab.freedesktop.org/drm/intel/issues/592 Signed-off-by: Kai Vehmanen <kai.vehmanen(a)linux.intel.com> --- sound/hda/hdac_regmap.c | 1 - 1 file changed, 1 deletion(-) diff --git a/sound/hda/hdac_regmap.c b/sound/hda/hdac_regmap.c index 906b1e20bae0..286361ecd640 100644 --- a/sound/hda/hdac_regmap.c +++ b/sound/hda/hdac_regmap.c @@ -363,7 +363,6 @@ static const struct regmap_config hda_regmap_cfg = { .reg_write = hda_reg_write, .use_single_read = true, .use_single_write = true, - .disable_locking = true, }; /** -- 2.17.1

[alsa-devel] [PATCH] ASoC: Fix NULL dereference at freeing
by Takashi Iwai 08 Jan '20

08 Jan '20

When an ASoC driver with pcm_destruct component ops is freed before the PCM object instantiation (e.g. deferring the probe), it hits an Oops at snd_soc_pcm_component_free() that calls the pcm_destruct ops unconditionally. Fix it by adding a NULL-check of rtd->pcm before calling callbacks.
