[alsa-devel] [PATCH v2 0/3] Make the audio component binding more generic
by Takashi Iwai 20 Jul '18

20 Jul '18

Hi, this is a preliminiary patch set to convert the existing i915 / HD-audio component binding to be applicable to other drivers like radeon / amdgpu. This patchset itself doesn't change the functionality but only renames and split to a new drm_audio_component stuff from i915_audio_component. The actual usage of the new API will follow once after this one gets reviewed / accepted. The whole patches (including this patchset) are found in topic/hda-acomp branch of sound.git tree. BTW, since the whole stuff is about the audio binding, I suppose these will go through sound git tree. Let me know if anyone has concerns. Thanks!

[alsa-devel] [PATCH - ALSA JACK plugin 1/1] jack: Only allow ALSA periods multiple of JACKd period
by twischer＠de.adit-jv.com 19 Jul '18

19 Jul '18

From: Laxmi Devi <ldevi(a)de.adit-jv.com> There is a higher Xrun probability whenever the ALSA period is not a multiple of the JACKd period and the ALSA buffer is only twice the period. Allowing ALSA buffers of min. 3x period is not a good solution because this would increase the latency. As an example in case of ALSA is using a period of 11 frames and JACK a period of 12 frames and a buffer of 22 frames (2x ALSA period) is used: - The buffer is filled and contains 22 frames - JACK is reading 12 frames. Buffer is only containing 10 frames - Now, ALSA has to be scheduled exactly after the last JACK read and before the next read. Otherwise we will get an Xrun In case of ALSA is using a multiple period of JACK, JACK can always read 2 periods before an Xrun if the buffer was full. In case of ALSA is using a period of 12 frames and JACK a period of 11 frames and a buffer of 24 frames (2x ALSA period) is used: - The buffer is filled and contains 24 frames - JACK is reading 11 frames. Buffer is now containing 13 frames. But ALSA can still not write to the buffer - JACK reads 11 additional frames. Buffer contains 2 frames - Now, ALSA has to be scheduled exactly after the last JACK read and before the next read. Otherwise we will get an Xrun In case of ALSA is using a multiple period of JACK, ALSA can always write to the buffer as long as the buffer is filled with less or equal of half of buffer. Therefore this patch enforces an ALSA period which is always a multiple of the JACKd period.

[alsa-devel] [PATCH 1/5] ASoC: wm_adsp: Correct algorithm list allocation size
by Charles Keepax 19 Jul '18

19 Jul '18

Commit 6396bb221514 ("treewide: kzalloc() -> kcalloc()") was overlooked when doing some refactoring to the algorithm list handling, which lead to twice as much buffer being allocated as required for reading the algorithm list. A kcalloc is no longer appropriate since the allocation size is now in bytes not registers, as such change back to kzalloc.

[alsa-devel] [PATCH RESEND 00/15] ASoC: meson: add axg audio subsystem support
by Jerome Brunet 19 Jul '18

19 Jul '18

This patchset adds support for the audio subsystem found on Amlogic's axg SoC family. The first SoC of this family is the A113D/X targeted at smart speaker application. The G12a SoC family, Amlogic next-gen STB chipset, will reuse this audio subsystem with a few changes. This patchset implements the DPCM machine driver and the different components it made of. Several components are still missing, such spdif input and pdm, and will submitted later on. The fancier part of this patchset is probably around the TDM. Properly modeling the SoC architecture and its capatilities made things a little more complex than usual (details in the related commit descriptions) If necessary, this patchset could broken into smaller series. For the intial submission, I wanted to give a global view of the subsystem. Hopefully, it will make it a bit easier to understand.

[alsa-devel] [PATCH - usb-audio v2 1/1] ALSA: usb-audio: Allow changing from a bad sample rate
by Adam Goode 19 Jul '18

19 Jul '18

If the audio device is externally clocked and set to a rate that does not match the external clock, the clock will never be valid and we cannot set the rate successfully. To fix this, allow a rate change even if the clock is initially invalid, and validate again after the rate is changed. This fixes problems with MOTU UltraLite AVB hardware over USB.

[alsa-devel] [PATCH v2 0/5] ASoC: core: add support to card re-bind using component framework
by Srinivas Kandagatla 18 Jul '18

18 Jul '18

During discussion regarding card re-binding when components unregister and register back at https://lkml.org/lkml/2018/7/9/785 it was suggested that component framework can be added into core to provide this feature. With this new changes the card will re-bind once the dependent component re-registers after unregistering. This works based on the match done from component name using component framework. I have tested this patch with qdsp start-stop and module-load-unload usecase for more than 10000 times in loop on Qcom platforms. Thanks, srini Changes since v1: - Added new flag to enable/disable auto bind at card level, It is useful if machine driver/module is really removed/unloaded. Also to help cleanup the master component. Without this we will endup with a memory leak if the machine driver and memory associated with card are removed. - removed unregister from unbind callback. - updated match function as suggested by Vinod. - Added qdsp6 cleanup patches to this series.

[alsa-devel] [PATCH 0/4] ALSA: rawmidi cleanups
by Takashi Iwai 18 Jul '18

18 Jul '18

Hi, this is a patchset mainly as a cleanup of rawmidi code, and most of them are just coding style or readability fixes without functional behavior changes. The last patch replaces kmalloc() with kvmalloc() for buffer allocations, which may fail frequently as is.

[alsa-devel] [PATCH] ALSA: rawmidi: Change resized buffers atomically
by Takashi Iwai 17 Jul '18

17 Jul '18

The SNDRV_RAWMIDI_IOCTL_PARAMS ioctl may resize the buffers and the current code is racy. For example, the sequencer client may write to buffer while it being resized. As a simple workaround, let's switch to the resized buffer inside the stream runtime lock.

[alsa-devel] [PATCH] [RFC] y2038: globally rename compat_time to old_time32
by Arnd Bergmann 17 Jul '18

17 Jul '18

Christoph Hellwig suggested a slightly different path for handling backwards compatibility with the 32-bit time_t based system calls: Rather than simply reusing the compat_sys_* entry points on 32-bit architectures unchanged, we get rid of those entry points and the compat_time types by renaming them to something that makes more sense on 32-bit architectures (which don't have a compat mode otherwise), and then share the entry points under the new name with the 64-bit architectures that use them for implementing the compatibility. The following types and interfaces are renamed here, and moved from linux/compat_time.h to linux/time32.h: old new --- --- compat_time_t old_time32_t struct compat_timeval struct old_timeval32 struct compat_timespec struct old_timespec32 struct compat_itimerspec struct old_itimerspec32 ns_to_compat_timeval() ns_to_old_timeval32() get_compat_itimerspec64() get_old_itimerspec32() put_compat_itimerspec64() put_old_itimerspec32() compat_get_timespec64() get_old_timespec32() compat_put_timespec64() put_old_timespec32() I considered doing this only for those instances that are actually shared between 32-bit and 64-bit kernels, but doing it everywhere avoids duplication. This should make more sense for the 32-bit implementation, and the naming suggests that these interfaces are meant for 'old' syscalls only, and that they always operate on 32-bit time_t on both 32-bit and 64-bit architectures, something that may not be obvious from the compat_* naming. I'm not renaming the timex, rusage and itimerval structures, as we are still debating what the new interface will look like, and whether we will need a replacement at all. This also doesn't change the names of the syscall entry points, which can be done more easily when we actually switch over the 32-bit architectures to use them, at that point we need to change COMPAT_SYSCALL_DEFINEx to SYSCALL_DEFINEx with a new name, e.g. with a _time32 suffix. Suggested-by: Christoph Hellwig <hch(a)infradead.org> Link: https://lore.kernel.org/lkml/20180705222110.GA5698@infradead.org/ Signed-off-by: Arnd Bergmann <arnd(a)arndb.de> --- Both Deepa and I have pending syscall conversion patches, but if we can get consensus on the rename, they should be easy to rebase on top of this patch. The patch would be easy to split up in various ways, but since it is a trivial rename, I went for a big patch with the first attempt. --- arch/arm64/include/asm/compat.h | 6 +- arch/arm64/include/asm/stat.h | 2 +- arch/mips/include/asm/compat.h | 6 +- arch/mips/kernel/binfmt_elfn32.c | 14 ++-- arch/mips/kernel/binfmt_elfo32.c | 14 ++-- arch/parisc/include/asm/compat.h | 6 +- arch/powerpc/include/asm/compat.h | 6 +- arch/powerpc/kernel/asm-offsets.c | 8 +-- arch/powerpc/oprofile/backtrace.c | 2 +- arch/sparc/include/asm/compat.h | 6 +- drivers/media/v4l2-core/v4l2-compat-ioctl32.c | 4 +- fs/aio.c | 8 +-- fs/compat_binfmt_elf.c | 2 +- fs/compat_ioctl.c | 6 +- fs/select.c | 20 +++--- fs/timerfd.c | 12 ++-- fs/utimes.c | 12 ++-- fs/xfs/xfs_ioctl32.c | 2 +- fs/xfs/xfs_ioctl32.h | 2 +- include/linux/compat.h | 96 +++++++++++++-------------- include/linux/compat_time.h | 32 --------- include/linux/elfcore-compat.h | 8 +-- include/linux/restart_block.h | 4 +- include/linux/syscalls.h | 2 +- include/linux/time32.h | 25 +++++++ ipc/mqueue.c | 8 +-- ipc/msg.c | 6 +- ipc/sem.c | 10 +-- ipc/shm.c | 6 +- ipc/syscall.c | 2 +- ipc/util.h | 2 +- kernel/compat.c | 8 +-- kernel/futex_compat.c | 2 +- kernel/sched/core.c | 4 +- kernel/signal.c | 2 +- kernel/time/hrtimer.c | 8 +-- kernel/time/posix-stubs.c | 18 ++--- kernel/time/posix-timers.c | 30 ++++----- kernel/time/time.c | 58 ++++++++-------- net/bluetooth/hci_sock.c | 2 +- net/compat.c | 22 +++--- sound/core/pcm_compat.c | 14 ++-- sound/core/rawmidi_compat.c | 2 +- sound/core/timer_compat.c | 2 +- 44 files changed, 252 insertions(+), 259 deletions(-) delete mode 100644 include/linux/compat_time.h diff --git a/arch/arm64/include/asm/compat.h b/arch/arm64/include/asm/compat.h index 1a037b94eba1..4a89007db14a 100644 --- a/arch/arm64/include/asm/compat.h +++ b/arch/arm64/include/asm/compat.h @@ -86,11 +86,11 @@ struct compat_stat { compat_off_t st_size;

[alsa-devel] Bug in snd_pcm_ioplug_avail_update()?
by Rob Duncan 17 Jul '18

17 Jul '18

It seems to me that there's something wrong in snd_pcm_ioplug_avail_update() for capture IO plugins. Once a bunch of conditions are met it makes this call: __snd_pcm_mmap_begin(pcm, &areas, &offset, &size); result = io->data->callback->transfer(io->data, areas, offset, size); if (result < 0) return result; This transfers size frames from the IO plugin, which in general is not all the available data: it's limited by the amount of contiguous space in the mmap. However, the function returns like this: avail = snd_pcm_mmap_avail(pcm); if (avail > io->avail_max) io->avail_max = avail; return (snd_pcm_sframes_t)avail; But this is all the available data in the IO plugin, without considering the contiguous space limitation. This means that there is now uninitialized data in the mmap, and some data still in the IO plugin that has yet to be transferred. I'm running into this misbehaviour with a rate conversion plugin pulling data from an IO plugin. I get chunks of old data showing up later in the stream, I think because the mmap buffer is not being fully written to. I suspect that this avail mismatch tricks snd_pcm_rate_avail_update() into thinking that it can grab an integral number of periods of data from the mmap, which is not the case. But I'm quite tangled up trying to follow the control flow here so I could certainly be mistaken. I'd appreciate any insight into what might be going wrong. Thanks, Rob.

[alsa-devel] [PATCH] ALSA: emu8000: Use swap macro in snd_emu8000_sample_new
by Gustavo A. R. Silva 17 Jul '18

[alsa-devel] [PATCH v3] ASoC: hdac_hdmi: Program pin-port-mux during jack report event
by Sriram Periyasamy 17 Jul '18

17 Jul '18

During d3/d0 cycle, the connection selection index of all pins points to the default value. This needs to be restored to ensure audio is restored after d3/d0 cycle. So store the connection selection index and program it during jack report event which gets invoked in cases like d3/d0 cycle, hot plug detection when multiple displays are connected.

[alsa-devel] [V3] vga_switcheroo: set audio client id according to bound GPU id
by Jim Qu 17 Jul '18

17 Jul '18

On modern laptop, there are more and more platforms have two GPUs, and each of them maybe have audio codec for HDMP/DP output. For some dGPU which is no output, audio codec usually is disabled. In currect HDA audio driver, it will set all codec as VGA_SWITCHEROO_DIS, the audio which is binded to UMA will be suspended if user use debugfs to contorl power In HDA driver side, it is difficult to know which GPU the audio has binded to. So set the bound gpu pci dev to vga_switcheroo. if the audio client is not the third registration, audio id will set in vga_switcheroo enable function. if the audio client is the last registration when vga_switcheroo _ready() get true, we should get audio client id from bound GPU directly.

[alsa-devel] Boundary calculation
by Ricardo Biehl Pasquali 17 Jul '18

17 Jul '18

Hello. I can't get the tricky boundary calculation. Perhaps I'm missing some obvious thing, or maybe it's really some circumvent for a specific case that was not commented. The current calculation for boundary is: boundary = buffer_size; while (boundary * 2 <= LONG_MAX - buffer_size) boundary *= 2; I've checked out some repositories, specially alsa-driver in ALSA git, and I realized this calculation exists at least since 2001. I guess it was Jaroslav who wrote. Visualization of the calculation (B = buffer_size): LONG_MAX ------------------------------- \______________/ \__/ B * 4 B \______/ B * 2 \__/ B Why isn't a simpler calculation used instead? e.g.: /* closest multiple of buffer size less or equal LONG_MAX */ boundary = LONG_MAX - LONG_MAX % buffer_size; LONG_MAX ------------------------------- \__________________________/ B * 6 Cheers! pasquali

For playback, the packet lengths change dynamically, because the nominal sample rate (let alone the actual sample rate) often is not an integer multiple of the 1 kHz/8 kHz USB frame rate.

[alsa-devel] [PATCH 0/3] Make the audio component binding more generic
by Takashi Iwai 16 Jul '18

16 Jul '18

Hi, this is a preliminiary patch set to convert the existing i915 / HD-audio component binding to be applicable to other drivers like radeon / amdgpu. This patchset itself doesn't change the functionality but only renames and split to a new drm_audio_component stuff from i915_audio_component. The actual usage of the new API will follow once after this one gets reviewed / accepted. The whole patches (including this patchset) are found in topic/hda-acomp branch of sound.git tree. BTW, since the whole stuff is about the audio binding, I suppose these will go through sound git tree. Let me know if anyone has concerns. Thanks!

Sorry, not understood. Why they don't access the audio hardware? > Therefore, upper software could not get HDMI ELD info, can select a available card/output sink. > I am also confuse that if there is no ELD info, how driver to steam audio device to wake up itself? It's sort of a chicken-or-egg question. As long as it's i915 and HD-audio, the hotplug and ELD info transfer doesn't trigger the runtime PM since it's done via the direct callback. And ELD value is cached in HD-audio side. The exception is that if the notification is done during the PM operation. But, the connection and ELD query is performed at the end of codec resume, hence it'll be covered there. So in theory, ELD information should be passed from the GPU to HD-audio no matter whether runtime PM is enabled or not. BTW, please stop top-posting.

[alsa-devel] [PATCH 0/5] UAC3: Add Selectors and Processing Units.
by Jorge Sanjuan 16 Jul '18

16 Jul '18

This patchset is motivated by the addition of Multi Function Processing Units (MFPU) to an UAC3 topology where there could be signal processing algorithims applied to the audio signal. The MFPUs themself don't provide any useful control, they offer a description of what algorithims it supports and it is for Selector Units to take the bypass control of the dry (unprocessed) signal and the modified one. Moreover, Up/Down mixers may be needed in this topologies to control which outputs of the logical output cluster from the MFPU are to be passed as the final modified audio signal. These patches add support for Selector Units and Processing units for UAC3 and adds a couple fixes that I found while implemeting them: 1) Defualt naming of the virtual terminals was not accurate due to codes overlap between the three UAC standards. 2) UAC2 parsing of processing units was using UAC1 controls bitmap.

[alsa-devel] Applied "ASoC: hdmi-codec: fix routing" to the asoc tree
by Mark Brown 16 Jul '18

16 Jul '18

The patch ASoC: hdmi-codec: fix routing has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From d30e23d69981a4b665f5ce8711335df986576389 Mon Sep 17 00:00:00 2001 From: Russell King <rmk+kernel(a)armlinux.org.uk> Date: Sat, 14 Jul 2018 16:01:06 +0100 Subject: [PATCH] ASoC: hdmi-codec: fix routing Commit 943fa0228252 ("ASoC: hdmi-codec: Use different name for playback streams") broke hdmi-codec's routing between it's output "TX" widget and the S/PDIF or I2S streams by renaming the streams. Whether an error occurs or not is dependent on whether there is another widget called "Playback" registered by some other component - if there is, that widget will be (incorrectly) bound to the HDMI codec's "TX" output widget. If we end up connecting "TX" incorrectly, it can result in components not being started, causing no audio output. Since the I2S and S/PDIF streams now have different names, we can't use a static route at component level to describe the relationship, so arrange to dynamically create the route when the DAI driver is probed.

[alsa-devel] [PATCH v5 0/5] ASoC: add driver for Atmel I2S controller
by Codrin Ciubotariu 16 Jul '18

16 Jul '18

This is a rework of Cyrille's patches named: [PATCH v3 0/2] ASoC: add driver for Atmel I2S controller https://lkml.org/lkml/2015/9/29/454 This is the version 5 of the series, and addresses the received feedback on the mailing lists. This series applies on top of clk-next branch of clk/linux.git. Based on received feedback, I created a mux clock driver to select the I2S clock source, that also includes proper devicetree bindings and nodes. Also, I added the I2S nodes in sama5d2's devicetree, with the missing pin muxing for the second I2S controller. Alexandre Belloni plans to change the at91 fine grained clock nodes and he recommended to leave the bindings for this clock driver in the same (wrong) manner, so he could fix them all at once. This series of patches adds support to the new Atmel I2S controller embedded on sama5d2 SoCs. ChangeLog v4 -> v5 - removed patches: [PATCH v4 4/7] ASoC: atmel-i2s: dt-bindings: add DT bindings for I2S controller [PATCH v4 5/7] ASoC: atmel-i2s: add driver for the new Atmel I2S controller from this series since they were applied to the asoc tree at: https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git - addressed comments received on the mux clock; v3 -> v4 - as suggested by Rob Herring: - added a clock mux driver for I2S's clock control bit; - more precise description of I2S's devicetree bindings; - removed SoC and internal detalls from bindings; - addressed comments from Mark Brown; - added devicetree nodes and pin muxing for I2S; 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() Codrin Ciubotariu (3): dt-bindings: clk: at91: add an I2S mux clock clk: at91: add I2S clock mux driver ARM: dts: at91: sama5d2: add I2S clock muxing nodes Cyrille Pitchen (2): ARM: dts: at91: sama5d2: add nodes for I2S controllers ARM: dts: at91: sama5d2 Xplained: add pin muxing for I2S .../devicetree/bindings/clock/at91-clock.txt | 35 ++++++ arch/arm/boot/dts/at91-sama5d2_xplained.dts | 28 +++++ arch/arm/boot/dts/sama5d2.dtsi | 52 ++++++++ arch/arm/mach-at91/Kconfig | 4 + drivers/clk/at91/Makefile | 1 + drivers/clk/at91/clk-i2s-mux.c | 116 ++++++++++++++++++ 6 files changed, 236 insertions(+) create mode 100644 drivers/clk/at91/clk-i2s-mux.c -- 2.17.1

[alsa-devel] [PATCH] ASoC: hdmi-codec: fix routing
by Russell King 14 Jul '18

14 Jul '18

Commit 943fa0228252 ("ASoC: hdmi-codec: Use different name for playback streams") broke hdmi-codec's routing between it's output "TX" widget and the S/PDIF or I2S streams by renaming the streams. Whether an error occurs or not is dependent on whether there is another widget called "Playback" registered by some other component - if there is, that widget will be (incorrectly) bound to the HDMI codec's "TX" output widget. If we end up connecting "TX" incorrectly, it can result in components not being started, causing no audio output. Since the I2S and S/PDIF streams now have different names, we can't use a static route at component level to describe the relationship, so arrange to dynamically create the route when the DAI driver is probed.

[alsa-devel] [PATCH] ASoC: qdsp6: q6afe-dai: fix a range check in of_q6afe_parse_dai_data()
by Dan Carpenter 13 Jul '18

[alsa-devel] [PATCH 0/2] ASoC: add sound-name-prefix property
by Jerome Brunet 13 Jul '18

13 Jul '18

This patchset add support in ASoC to pick up name prefix from the component nodes when the component does not match the configuration table provided to the card. The need for this feature came from the platform I'm working on (Amlogic A113). On this platform, the card is made of several instances of each components. It relies heavily on prefixes to describe the routing between these components. The proposed solution benefits every other DT based sound cards, such as the simple card family. It allows to express the routing easily even when the card uses several instances of the same component, or different components with the same sink/source names (Playback, Capture, Output, etc ...)

[alsa-devel] [PATCH] ASoC: core: add support to card re-bind/unbind using component framework
by Srinivas Kandagatla 12 Jul '18

12 Jul '18

This patch aims at add achieving dynamic behaviour of audio card when the dependent components disappear and reappear. With this patch the card is removed if any of the dependent component is removed and card is added back if the dependent component comes back. All this is done using component framework and matching based on component name. Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla(a)linaro.org> --- During discussion regarding card re-binding when components unregister and register back at https://lkml.org/lkml/2018/7/9/785 it was suggested that component framework can be added into core to provide this feature. With this new changes the card will re-bind once the dependent component re-registers after unregistering. This works based on the match done from component name using component framework. I have tested this patch with qdsp start-stop usecase for more than 10000 times in loop on Qcom platforms. I will send qdsp side cleanup patches once I get some feedback on this patch. include/sound/soc.h | 5 ++++ sound/soc/soc-core.c | 70 ++++++++++++++++++++++++++++++++++++++++++++++++---- 2 files changed, 70 insertions(+), 5 deletions(-) diff --git a/include/sound/soc.h b/include/sound/soc.h index 870ba6b64817..b94149d29c0d 100644 --- a/include/sound/soc.h +++ b/include/sound/soc.h @@ -17,6 +17,7 @@ #include <linux/workqueue.h> #include <linux/interrupt.h> #include <linux/kernel.h> +#include <linux/component.h> #include <linux/regmap.h> #include <linux/log2.h> #include <sound/core.h> @@ -1088,6 +1089,10 @@ struct snd_soc_card { struct work_struct deferred_resume_work; + /* component framework related */ + bool components_added; + struct component_match *match; + /* lists of probed devices belonging to this card */ struct list_head component_dev_list; diff --git a/sound/soc/soc-core.c b/sound/soc/soc-core.c index 6d33634b934b..377ed8e67686 100644 --- a/sound/soc/soc-core.c +++ b/sound/soc/soc-core.c @@ -279,11 +279,31 @@ static inline void snd_soc_debugfs_exit(void) #endif +static int snd_soc_card_comp_compare(struct device *dev, void *data) +{ + struct snd_soc_component *component = NULL; + struct snd_soc_component *t; + + lockdep_assert_held(&client_mutex); + list_for_each_entry(t, &component_list, list) { + if (dev == t->dev) { + component = t; + break; + } + } + + if (component && !strcmp(component->name, data)) + return 1; + + return 0; +} + static int snd_soc_rtdcom_add(struct snd_soc_pcm_runtime *rtd, struct snd_soc_component *component) { struct snd_soc_rtdcom_list *rtdcom; struct snd_soc_rtdcom_list *new_rtdcom; + char *cname; for_each_rtdcom(rtd, rtdcom) { /* already connected */ @@ -300,6 +320,13 @@ static int snd_soc_rtdcom_add(struct snd_soc_pcm_runtime *rtd, list_add_tail(&new_rtdcom->list, &rtd->component_list); + if (!rtd->card->components_added) { + cname = devm_kasprintf(rtd->card->dev, GFP_KERNEL, + "%s", component->name); + component_match_add(rtd->card->dev, &rtd->card->match, + snd_soc_card_comp_compare, cname); + } + return 0; } @@ -835,6 +862,28 @@ static bool soc_is_dai_link_bound(struct snd_soc_card *card, return false; } +static int snd_soc_card_comp_bind(struct device *dev) +{ + struct snd_soc_card *card = dev_get_drvdata(dev); + + if (card->instantiated) + return 0; + + return snd_soc_register_card(card); +} + +static void snd_soc_card_comp_unbind(struct device *dev) +{ + struct snd_soc_card *card = dev_get_drvdata(dev); + + snd_soc_unregister_card(card); +} + +static const struct component_master_ops snd_soc_card_comp_ops = { + .bind = snd_soc_card_comp_bind, + .unbind = snd_soc_card_comp_unbind, +}; + static int soc_bind_dai_link(struct snd_soc_card *card, struct snd_soc_dai_link *dai_link) { @@ -2108,6 +2157,12 @@ static int snd_soc_instantiate_card(struct snd_soc_card *card) card->instantiated = 1; snd_soc_dapm_sync(&card->dapm); + if (!card->components_added) { + component_master_add_with_match(card->dev, + &snd_soc_card_comp_ops, + card->match); + card->components_added = true; + } mutex_unlock(&card->mutex); mutex_unlock(&client_mutex); @@ -3098,11 +3153,6 @@ static void snd_soc_component_cleanup(struct snd_soc_component *component) static void snd_soc_component_del_unlocked(struct snd_soc_component *component) { - struct snd_soc_card *card = component->card; - - if (card) - snd_soc_unregister_card(card); - list_del(&component->list); } @@ -3169,8 +3219,17 @@ int snd_soc_add_component(struct device *dev, snd_soc_component_add(component); + ret = component_add(dev, NULL); + if (ret < 0) { + dev_err(dev, "ASoC: Failed to add Component: %d\n", ret); + goto err_comp; + } + return 0; +err_comp: + soc_remove_component(component); + snd_soc_unregister_dais(component); err_cleanup: snd_soc_component_cleanup(component); err_free: @@ -3218,6 +3277,7 @@ static int __snd_soc_unregister_component(struct device *dev) mutex_unlock(&client_mutex); if (found) { + component_del(dev, NULL); snd_soc_component_cleanup(component); } -- 2.16.2

[alsa-devel] [PATCH v2] ASoC: hdac_hdmi: Program pin-port-mux during jack report event
by Sriram Periyasamy 11 Jul '18

11 Jul '18

During d3/d0 cycle, the connection selection index of all pins points to the default value. This needs to be restored to ensure audio is restored after d3/d0 cycle. So store the connection selection index and program it during jack report event which gets invoked in cases like d3/d0 cycle, hot plug detection when multiple displays are connected.

[alsa-devel] poll blocked after prepare state
by Harald Schuster 11 Jul '18

11 Jul '18

Hi I have a problem when I got an underrun that my playback path is not working correctly any longer. I debugged the problem and see that the snd_pcm_direct_prepare function is called and than the snd_pcm_dshare_start function. After this the snd_pcm_write_areas is called and the snd_pcm_wait_nocheck never returns. He is blocked in the poll function. Is there any solution for this problem?! best regards Harald

[alsa-devel] [PATCH - usb-audio 1/1] ALSA: usb-audio: Allow changing from a bad sample rate
by Adam Goode 11 Jul '18

11 Jul '18

If the audio device is externally clocked and set to a rate that does not match the external clock, the clock will never be valid and we cannot set the rate successfully.

The rt5651 does not have a built-in speaker amplifier, so it is often used together with an external amplifier.

[alsa-devel] [PATCH 1/5] ASoC: rt5651: Fix workqueue cancel vs irq free race on remove
by Hans de Goede 10 Jul '18

10 Jul '18

On removal we must free the IRQ *before* cancelling the jack-detect work, so that the jack-detect work cannot be rescheduled by the IRQ. Before this commit we were cancelling the jack-detect work from the driver remove callback, while relying on devm to free the IRQ, which happens after the remove callback. This is the wrong order. This commit uses a devm-action to register a devm callback which cancels the work, before requesting the IRQ (devm tears things down in reverse order). This also allows us to remove the now empty remove driver callback.

[alsa-devel] [PATCH] dma: add support for reporting pause and resume separately
by Marek Szyprowski 09 Jul '18

09 Jul '18

'cmd_pause' DMA channel capability means that respective DMA engine supports both pausing and resuming given DMA channel. However, in some cases it is important to know if DMA channel can be paused without the need to resume it. This is a typical requirement for proper residue reading on transfer timeout in UART drivers. There are also some DMA engines with limited hardware, which doesn't really support resuming. Reporting pause and resume capabilities separately allows UART drivers to properly check for the really required capabilities and operate in DMA mode also in systems with limited DMA hardware. On the other hand drivers, which rely on full channel suspend/resume support, should now check for both 'pause' and 'resume' features. Existing clients of dma_get_slave_caps() have been checked and the only driver which rely on proper channel resuming is soc-generic-dmaengine-pcm driver, which has been updated to check the newly added capability. Existing 'cmd_pause' now only indicates that DMA engine support pausing given DMA channel.

Sounds like a bug in the HDA driver. The HDA driver should cache what it needs or power it back up when there is an ioctl/etc. that requires something that can't be cached.

[alsa-devel] [RESEND][PATCH] ASoC: hdac_hdmi: Program pin-port-mux during jack report event
by Sriram Periyasamy 09 Jul '18

During d3/d0 cycle, the connection selection index of all pins points to the default value. This needs to be restored to ensure audio is restored after d3/d0 cycle. So store the connection selection index and program it during jack report event which gets invoked in cases like d3/d0 cycle, hot plug detection when multiple displays are connected.

[alsa-devel] How to add new sound card with ASoC generic driver
by Riccardo Casagrande 09 Jul '18

09 Jul '18

Hello, I'm new to ALSA and linux in general, I need help from who knows well ALSA due to the tight schedule of the project. I'm working on a Yocto project on NXP i.MX6Quad. The hardware architetture is this: the i.MAX6Quad has 6 output connected to 3 ST FDA2100 and 2 input from ADC. In the first step what I need is simply to enable 6 output and send I2S audio to FDAs. In the second step is required a clock for ADC and enable input ports. I spent days/weeks reading docs, examples etc without success. I understood that working on device tree file and setting a simple audio card with generic codec properly is the answer, but my knowledge is almost nothing. I followed these docs/thread https://elixir.bootlin.com/linux/latest/source/Documentation/devicetree/bin… https://community.nxp.com/thread/475428 but compiling I have syntax errors on device tree file. There is someone who can help me step by step? Thanks in advance Riccardo

For mic and line input is works as expected, but for sidetone and master volume I had to use "proper" names for mixer controls, see bellow: /* Input mixer */ static const struct snd_kcontrol_new max9867_input_mixer_controls[] = { SOC_DAPM_DOUBLE("Mic Switch", MAX9867_INPUTCONFIG, 6, 4, 1, 0), SOC_DAPM_DOUBLE("Line Switch", MAX9867_INPUTCONFIG, 7, 5, 1, 0), }; /* Output mixer */ static const struct snd_kcontrol_new max9867_output_mixer_controls[] = { SOC_DAPM_DOUBLE_R("Line Bypass Switch", MAX9867_LEFTLINELVL, MAX9867_RIGHTLINELVL, 6, 1, 1), }; /* Sidetone mixer */ static const struct snd_kcontrol_new max9867_sidetone_mixer_controls[] = { SOC_DAPM_DOUBLE("Sidetone Switch", MAX9867_SIDETONE, 6, 7, 1, 0), }; /* Line out switch */ static const struct snd_kcontrol_new max9867_line_out_control = SOC_DAPM_DOUBLE_R("Switch", MAX9867_LEFTVOL, MAX9867_RIGHTVOL, 6, 1, 1); static const struct snd_soc_dapm_widget max9867_dapm_widgets[] = { SND_SOC_DAPM_INPUT("MICL"), SND_SOC_DAPM_INPUT("MICR"), SND_SOC_DAPM_INPUT("LINL"), SND_SOC_DAPM_INPUT("LINR"), SND_SOC_DAPM_MIXER("Left Input Mixer", MAX9867_PWRMAN, 6, 1, max9867_input_mixer_controls, ARRAY_SIZE(max9867_input_mixer_controls)), SND_SOC_DAPM_MIXER("Right Input Mixer", MAX9867_PWRMAN, 5, 1, max9867_input_mixer_controls, ARRAY_SIZE(max9867_input_mixer_controls)), SND_SOC_DAPM_ADC("ADCL", "HiFi Capture", MAX9867_PWRMAN, 1, 0), SND_SOC_DAPM_ADC("ADCR", "HiFi Capture", MAX9867_PWRMAN, 0, 0), SND_SOC_DAPM_MIXER("Digital", SND_SOC_NOPM, 0, 0, max9867_sidetone_mixer_controls, ARRAY_SIZE(max9867_sidetone_mixer_controls)), SND_SOC_DAPM_MIXER("Output Mixer", SND_SOC_NOPM, 0, 0, max9867_output_mixer_controls, ARRAY_SIZE(max9867_output_mixer_controls)), SND_SOC_DAPM_DAC("DACL", "HiFi Playback", MAX9867_PWRMAN, 3, 0), SND_SOC_DAPM_DAC("DACR", "HiFi Playback", MAX9867_PWRMAN, 2, 0), SND_SOC_DAPM_SWITCH("Master Playback", SND_SOC_NOPM, 0, 0, &max9867_line_out_control), SND_SOC_DAPM_OUTPUT("LOUT"), SND_SOC_DAPM_OUTPUT("ROUT"), }; static const struct snd_soc_dapm_route max9867_audio_map[] = { {"Left Input Mixer", "Mic Switch", "MICL"}, {"Right Input Mixer", "Mic Switch", "MICR"}, {"Left Input Mixer", "Line Switch", "LINL"}, {"Right Input Mixer", "Line Switch", "LINR"}, {"ADCL", NULL, "Left Input Mixer"}, {"ADCR", NULL, "Right Input Mixer"}, {"Digital", "Sidetone Switch", "ADCL"}, {"Digital", "Sidetone Switch", "ADCR"}, {"DACL", NULL, "Digital"}, {"DACR", NULL, "Digital"}, {"Output Mixer", "Line Bypass Switch", "LINL"}, {"Output Mixer", "Line Bypass Switch", "LINR"}, {"Output Mixer", NULL, "DACL"}, {"Output Mixer", NULL, "DACR"}, {"Master Playback", "Switch", "Output Mixer"}, {"LOUT", NULL, "Master Playback"}, {"ROUT", NULL, "Master Playback"}, }; With other control names than "Digital" for sidetone digital mixer, sidetone switch is shown separately from sidetone volume. The same for master volume switch, which is bind with master volume only once its name is "Master Playback". Is it intended to work this way or there is some other, more elegant way how to bind mute switch with volume control. (above solution seem too fragile to me) Thank you, ladis

[alsa-devel] Hiding some of the controls defined in codec driver from machine driver context
by Giedrius Trainavičius 09 Jul '18

09 Jul '18

Hello, Is it possible to 'hide' some of the controls of the codec in the machine driver? The codec I'm using exposes many advanced controls which are useful for board developers, but not for the end user, so I'd like to define my own 'simplified' controls, and take care of board specific logic internally in the machine driver. I found this old discussion on the topic: https://www.spinics.net/lists/alsa-devel/msg36386.html - I'm targeting kernel 4.14, maybe there's already some means to achieve this? Thank you! Giedrius.

Once you start streaming audio to attached displays, user space opens the codec device and this causes the HDA controller to runtime resume. If the discrete GPU is suspended at that moment, it will be powered on and kept powered on as long as user space is streaming audio. Do you need to runtime resume the HDA controller even if user space isn't streaming audio? Why, and in which situation exactly? You're saying above that the HDA controller isn't runtime resumed on hotplug of a display. Is that necessary to retrieve ELD or something? I'm not sure if there's code in the HDA driver to acquire a runtime PM ref on HPD, but maybe it's necessary. Or maybe the code is there but somehow no HPD interrupt is received by the HDA driver? Thanks, Lukas

[alsa-devel] Getting a notification of snd_kcontrol value change, defined in codec, in machine driver
by Giedrius Trainavičius 08 Jul '18

08 Jul '18

Hey, What would be the best way in machine driver to learn about changes of alsa mixer control values? The controls are defined in the codec driver. The intended use case would be to use the current volume setting for the codec on the board to forward to a dedicated microcontroller for visual feedback. I am aware that this could be bridged over via a user space program, but I will have to forward the current PCM stream format to the MCU anyway from hw_params, so ideally I would like all of this functionality contained in the machine driver. Thank you, Giedrius.

[alsa-devel] Can't detect "XRUNs"
by Raphaël Dingé 05 Jul '18

05 Jul '18

Hi, I don't get audio drop notification "XRUNs" in /proc/kmsg. Not sure if this is the right mailing list as maybe my question is more kernel related, but I'll try a shot here. I'm currently making a proof of concept to see if I can run a quite CPU hungry audio application running without audio drops over time given a set of tests. In particular I want to automate playback buffer underruns detection so that I don't have to sit and listen closely when they happen. With some very extreme tests, I can hear that there are audio drops all over the place. I have 2 audio cards in the system, one is audio over HDMI, and the other one is an USB audio card that supports audio class definition. In both case the sound is working as I would expect. The system itself is an Intel NUC i7. I configured the kernel with CONFIG_SND_DEBUG=y, CONFIG_SND_PCM_XRUN_DEBUG=y and CONFIG_SND_VERBOSE_PROCFS=y as well as echo 5 > /proc/asound/cardX/pcmYp/xrun_debug with X and Y the card and pcm stream of interest, and so hw:X,Y when opening the device with snd_pcm_open. Then I watch the output of the ksyslog interface using cat /proc/kmsg When an audio drop occurs, there is nothing about XRUNs or whatever it is called. I don't even know what kind of log message it should look like, and can't find it on google as well. With audio over HDMI, I have some occurence of ALSA: PCM: [Q] Lost interrupts? that seems more of less related to audio drops, but not always. With the USB audio card, I have nothing. I tried to write to the xrun_injection proc file in the stream, but nothing happens as well. Finally I log any occurence of snd_pcm_writei returning a negative number, but that never happens as well. Am I missing something completely? Thanks for any information on that matter, Raphael

[alsa-devel] [PATCH v2 0/2] slimbus: Add Stream Support
by Srinivas Kandagatla 05 Jul '18

05 Jul '18

Thanks to Vinod and Stephen for reviewing v1 patchset This v2 patchset adds basic stream support for SLIMbus devices and controllers. Mostly inspired by soundwire stream patches. But slimbus stream is much simpler compared to soundwire >From slim_device side, we have below 6 new apis. slim_stream_allocate() - allocating runtime slim stream slim_stream_prepare() - to configure runtime stream with config slim_stream_enable() - enable channels/ports for data slim_stream_disable() - disable channels/ports. slim_stream_unprepare() - un configure runtime stream slim_stream_free() - free all associated memory. >From Controller side: Data channel Management and reconfiguration messages are applicable for all the controllers which are inline with SLIMbus specs. However light weight controller like NGD which have user specific implementation of some messages need to be invoked instead of standard message commands. For usecases like this simple enable/disable stream apis are provided. Assumptions: 1> Current design assumes that the channel and ports are statically allocated to the device during SoC integration, which is the case with all the Qualcomm SoCs. 2> One-to-One mapping between Port and Channel, SLIMBus versions earlier than 2.0 has only one endpoint per port. Current patchset can be extended to support more than one endpoints per port. 3> Only audio usecase, This patchset only supports Isochronous and Push/Pull transport protocols, which are sufficient for audio use cases. 4> DSP does all the data handling for the allocated channels. Which is true for Qcom SoCs. TODO: Bandwidth management. Dependency: This patchset has dependency on the NGD driver https://patchwork.kernel.org/patch/10474959/ Tested this patchset with WCD9335 codec playback and capture on DB820c using 4.18-rc1 with qdsp6 + slim tx patches merged in sound.git.

[alsa-devel] [PATCH v3] ALSA: core: Allow drivers to set R/W wait time.
by Liam Girdwood 04 Jul '18

04 Jul '18

Currently ALSA core blocks userspace for about 10 seconds for PCM R/W IO. This needs to be configurable for modern hardware like DSPs where no pointer update in milliseconds can indicate terminal DSP errors. Add a substream variable to set the wait time in ms. This allows userspace and drivers to recover more quickly from terminal DSP errors.

[alsa-devel] [PATCH 1/2] ALSA: pcm: trace XRUN event at injection, too
by Takashi Iwai 04 Jul '18

04 Jul '18

The PCM xrun injection triggers directly snd_pcm_stop() without the standard xrun handler, hence it's not recorded on the event buffer. Ditto for snd_pcm_stop_xrun() call and SNDRV_PCM_IOCTL_XRUN ioctl. They are inconvenient from the debugging POV. Let's make them to trigger XRUN via the standard helper more consistently.

[alsa-devel] [PATCH v3 00/13] Enable HDA Codec support on Intel Platforms
by Pierre-Louis Bossart 04 Jul '18

04 Jul '18

Many Intel platforms (SKL, KBL) etc. in the market supports enhanced audio capabilities which also includes DSP processing. The default HDaudio legacy driver does not allow for the use of the DSP, this patch set makes it possible while reusing existing code for HDAudio codecs and without significant changes to the legacy driver. This v3 is not split into two batches as done for v1 and v2, but keeps the same logical progression. The first three patches are mostly data structure changes, the DSP support capability is added then with an ASoC HDA driver and the last patches are fixes required for Skylake+. The changes to the HDAudio legacy driver are minimal. Tests were run successfully on multiple platforms (Dell XPS13, KBL NUC, APL NUC and LeafHill reference board). Credits: all the initial code was written by Rakesh Ughreja, the rebase to broonie/for-next, cleanups and additional tests were done by Pierre Bossart. Changes v3: - port to component model - additional tests on ApolloLake and KabyLake NUC devices - cleanups (alignment, typos, etc) Changes v2: - Resolved review comments and rebased to latest kernel. - added module load support for codec drivers.

Add support for the es7241 which is a simple 2 channels analog to digital converter. Changes since v1: [0] * Add missing break as reported by smatch [1] My device is hardwired in slave mode, which probably why this slipped through unnoticed. Changes since v2: [2] * Supply are now required dt properties * Add a dt property to state the serial interface configuration [0]: https://lkml.kernel.org/r/20180629152444.21525-1-jbrunet@baylibre.com [1]: https://lkml.kernel.org/r/20180630082829.qwnhkk4f76n32omm@mwanda [2]: https://lkml.kernel.org/r/20180630172241.10806-1-jbrunet@baylibre.com Jerome Brunet (2): ASoC: es7241: add dt-bindings documentation for the es7241 adc ASoC: es7241: add es7241 codec support .../devicetree/bindings/sound/everest,es7241.txt | 28 ++ sound/soc/codecs/Kconfig | 4 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/es7241.c | 322 +++++++++++++++++++++ 4 files changed, 356 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/everest,es7241.txt create mode 100644 sound/soc/codecs/es7241.c -- 2.14.4

[alsa-devel] [PATCH 1/2] jack: Allow build with older alsa-lib
by Takashi Iwai 03 Jul '18

03 Jul '18

[alsa-devel] [PATCH] ASoC: rt5682: add button detection mode control
by Bard Liao 03 Jul '18

[alsa-devel] Applied "ASoC: pxa-ssp: mark expected switch fall-through" to the asoc tree
by Mark Brown 03 Jul '18

03 Jul '18

The patch ASoC: pxa-ssp: mark expected switch fall-through has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From e0431de301cbb8e3915261dfff4d0b072738de69 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R.

[alsa-devel] [PATCH 1/6] ASoC: AMD: Always stop ch2 first
by Daniel Kurtz 03 Jul '18

03 Jul '18

Commit 6b116dfb4633a ("ASoC: AMD: make channel 1 dma as circular") made both channels circular, so this comment and logic no longer applies. Always stop ch2 (the channel closest to the output) before ch1. This ensures that the downstream circular DMA channel does not continue to play/capture repeated samples after the upstream circular DMA channel has already stopped.

[alsa-devel] [PATCH 0/2] ASoC: atmel-i2s: Remove unnecessary audio PLL clock
by Codrin Ciubotariu 03 Jul '18

03 Jul '18

Thanks to Quentin Schulz's patch: commit 1a1a36d72e3d ("clk: at91: clk-generated: make gclk determine audio_pll rate") the generated clock (gclk) itself is able to configure the audio PLL clock (aclk). For this reason, the I2S driver no longer needs to set aclk, but only gclk. This patchet removes all references to the audio PLL clock from the driver and updates the driver's bindings.

[alsa-devel] [PATCH] snd_interval_refine_first/last: exclude value only if also excluded before

03 Jul '18

From: Timo Wischer <twischer(a)de.adit-jv.com> Without this commit the following intervals [x y), (x y) were be replaced to (y-1 y) by snd_interval_refine_last(). This was also done if y-1 is part of the previous interval. With this changes it will be replaced with [y-1 y) in case of y-1 is part of the previous interval. A similar behavior will be used for snd_interval_refine_first(). This solves the issue reported here: https://bugzilla.opensuse.org/show_bug.cgi?id=1033179 and work arounded with commit e736715 ("pcm: dmix: Disable var_periodsize as default").

[alsa-devel] [PATCH v2] ALSA: core: Allow drivers to set R/W wait time.
by Liam Girdwood 02 Jul '18

02 Jul '18

Currently ALSA core blocks userspace for about 10 seconds for PCM R/W IO. This needs to be configurable for modern hardware like DSPs where no pointer update in milliseconds can indicate terminal DSP errors. Add a substream variable to set the wait time in ms. This allows userspace and drivers to recover more quickly from terminal DSP errors.

Hello, I have some issues with alsa-lib-devel for centos 7 , I'm working with gcc7.2.1 , I achieved the alsa-lb and compiled with gcc-7.2.1, my question where I can find alsa-lib-devel sources to compile it with my compiler? Additional question that I have it's about backward compatibility I saw that alsa-lib-devel-1.1.4.1-2.el7.x86_64.rpm doesn't have file alsa/iatomic.h as it was for Centos 5, could someone explain me please were I can achieve the functions that were in alsa/iatomic.h Thanks in advance, Max

[alsa-devel] [PATCH RFC] ASoC: pxa-ssp: remove .set_pll() and .set_clkdiv() callbacks
by Daniel Mack 02 Jul '18

02 Jul '18

The .set_pll() and .set_clkdiv() callbacks are considered legacy and should not be used anymore. In order to support PXA boards on DT platforms, remove them and let the code figure out the correct dividers and PLL base frequencies itself. Signed-off-by: Daniel Mack <daniel(a)zonque.org> --- I'd appreciate some review of this one. The only PXA3xx based platform I have access to uses the EXTCLK clocking source, but this patch changes the way the internal audio PLL works. Hence, I could only complile-test it for now. The PLL lookup table is taken from the datasheet, so it should be fine, but I'm not sure whether I got the mclk/bclk/fs calculations right, so a 2nd pair of eyes would help to avoid regressions. Given that the PXA platform has very little active mainline users, another option would be to just merge it and fix regressions if someone reports them. Once this is applied, I'll post another patch that removes the calculations and the calls to snd_soc_dai_set_{clkdiv,pll} from the zylonite and magician machine drivers.

[alsa-devel] [PATCH] ASoC: Intel: kbl_da7219_max98357a: Map BTN_0 to KEY_PLAYPAUSE
by mac.chiang＠intel.com 30 Jun '18

30 Jun '18

From: Mac Chiang <mac.chiang(a)intel.com> On kbl_rt5663_max98927, commit 38a5882e4292 ("ASoC: Intel: kbl_rt5663_max98927: Map BTN_0 to KEY_PLAYPAUSE") This key pair mapping to play/pause when playing Youtube The Android 3.5mm Headset jack specification mentions that BTN_0 should be mapped to KEY_MEDIA, but this is less logical than KEY_PLAYPAUSE, which has much broader userspace support. For example, the Chrome OS userspace now supports KEY_PLAYPAUSE to toggle play/pause of videos and audio, but does not handle KEY_MEDIA. Furthermore, Android itself now supports KEY_PLAYPAUSE equivalently, as the new USB headset spec requires KEY_PLAYPAUSE for BTN_0. https://source.android.com/devices/accessories/headset/usb-headset-spec The same fix is required on Chrome kbl_da7219_max98357a.

[alsa-devel] [PATCH] ALSA: snd-aoa: add of_node_put() in error path
by Nicholas Mc Guire 29 Jun '18

29 Jun '18

Both calls to of_find_node_by_name() and of_get_next_child() return a node pointer with refcount incremented thus it must be explicidly decremented here after the last usage. As we are assured to have a refcounted np either from the initial of_find_node_by_name(NULL, name); or from the of_get_next_child(gpio, np) in the while loop if we reached the error code path below, an x of_node_put(np) is needed.

[alsa-devel] snd_pcm_hw_params_set_buffer_time_near fails with "Invalid argument" when var_periodsize is enabled
by Wischer, Timo (ADITG/ESB) 29 Jun '18

Hi all, at the moment I am investigating in the issue described in [1]. This issue is already avoided by a workaround [2]. I am able to reproduce the issue with a more simple aplay use case using the following configuration: pcm_slave.adr3_tdm_8ch { pcm { type hw card "Loopback" device 0 } rate 48000 period_size 128 buffer_size 1024 channels 2 } pcm.dshare_Playback_3 { type dmix ipc_key 600 ipc_perm 0660 ipc_gid audio var_periodsize true slave adr3_tdm_8ch } pcm.AdevAcousticoutSpeech { type rate slave.pcm dshare_Playback_3 slave.rate 48000 } $ modprobe snd_aloop $ aplay -v --period-size=352 -c2 -fS16_LE -r22500 -D AdevAcousticoutSpeech /dev/urandom aplay: ../../alsa-utils-1.1.5/aplay/aplay.c:1390: set_params: Assertion `err >= 0' failed. Aborted by signal Aborted... It looks like the refinement fails. Now, I need your help because the intervals seems not to be handled in the same way in each function and I want to understand what is the correct interpretation of an interval. For example snd_interval_checkempty() and snd_interval_single() conflicting with each other. snd_interval_checkempty() interprets (x x] and [x x) as an empty set but snd_interval_single() does not. (x x) seems not to be an empty set as implemented by snd_interval_single(). Therefore could someone please explain me what is the correct interpretation of the snd_interval_t in combination with openmin and openmax. The following seems to be consistent (x x+1) and [x x+1) → x (see snd_interval_single() and snd_interval_value()) but it is different to what I have learnt at university. So it would be very helpful if someone could direct me to the right definition. So I hope I could easier solve this issue.

[alsa-devel] [PATCH v2] ALSA: hda - Handle pm failure during hotplug
by Takashi Iwai 29 Jun '18

29 Jun '18

From: Chris Wilson <chris(a)chris-wilson.co.uk> Obtaining the runtime pm wakeref can fail, especially in a hotplug scenario where i915.ko has been unloaded. If we do not catch the failure, we end up with an unbalanced pm. [ Additional changes: hdmi_present_sense() checks the return value and handle only a negative error case and bails out only if it's really still suspended. Also, snd_hda_power_down() is called at the error path so that the refcount is balanced. Along with it, the spec->pcm_lock is taken outside hdmi_present_sense() in the caller side, so that it won't cause deadlock at reentrace via runtime resume. -- tiwai ] References: 222bde03881c ("ALSA: hda - Fix mutex deadlock at HDMI/DP hotplug") Signed-off-by: Chris Wilson <chris(a)chris-wilson.co.uk> Cc: <stable(a)vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai(a)suse.de> --- sound/pci/hda/patch_hdmi.c | 18 +++++++++++++----- 1 file changed, 13 insertions(+), 5 deletions(-) diff --git a/sound/pci/hda/patch_hdmi.c b/sound/pci/hda/patch_hdmi.c index 98e1c411c56a..9e3916ed2588 100644 --- a/sound/pci/hda/patch_hdmi.c +++ b/sound/pci/hda/patch_hdmi.c @@ -764,8 +764,10 @@ static void check_presence_and_report(struct hda_codec *codec, hda_nid_t nid, if (pin_idx < 0) return; + mutex_lock(&spec->pcm_lock); if (hdmi_present_sense(get_pin(spec, pin_idx), 1)) snd_hda_jack_report_sync(codec); + mutex_unlock(&spec->pcm_lock); } static void jack_callback(struct hda_codec *codec, @@ -1628,21 +1630,23 @@ static void sync_eld_via_acomp(struct hda_codec *codec, static bool hdmi_present_sense(struct hdmi_spec_per_pin *per_pin, int repoll) { struct hda_codec *codec = per_pin->codec; - struct hdmi_spec *spec = codec->spec; int ret; /* no temporary power up/down needed for component notifier */ - if (!codec_has_acomp(codec)) - snd_hda_power_up_pm(codec); + if (!codec_has_acomp(codec)) { + ret = snd_hda_power_up_pm(codec); + if (ret < 0 && pm_runtime_suspended(hda_codec_dev(codec))) { + snd_hda_power_down_pm(codec); + return false; + } + } - mutex_lock(&spec->pcm_lock); if (codec_has_acomp(codec)) { sync_eld_via_acomp(codec, per_pin); ret = false; /* don't call snd_hda_jack_report_sync() */ } else { ret = hdmi_present_sense_via_verbs(per_pin, repoll); } - mutex_unlock(&spec->pcm_lock); if (!codec_has_acomp(codec)) snd_hda_power_down_pm(codec); @@ -1654,12 +1658,16 @@ static void hdmi_repoll_eld(struct work_struct *work) { struct hdmi_spec_per_pin *per_pin = container_of(to_delayed_work(work), struct hdmi_spec_per_pin, work); + struct hda_codec *codec = per_pin->codec; + struct hdmi_spec *spec = codec->spec; if (per_pin->repoll_count++ > 6) per_pin->repoll_count = 0; + mutex_lock(&spec->pcm_lock); if (hdmi_present_sense(per_pin, per_pin->repoll_count)) snd_hda_jack_report_sync(per_pin->codec); + mutex_unlock(&spec->pcm_lock); } static void intel_haswell_fixup_connect_list(struct hda_codec *codec, -- 2.17.1

29 Jun '18

The patch ASoC: mediatek: sub dai use list_head has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

Re: [alsa-devel] [PATCH] vgaswitchroo: set audio client id according to bound gpu client id

That is no longer the case since v4.17. The HDA controller now runtime suspends autonomously, see commit 07f4f97d7b4b ("vga_switcheroo: Use device link for HDA controller"). Your patch appears to be geared towards an older kernel version. Please retest on the laptop in question with a v4.17+ kernel. > I think the issue should be observed on both Intel+AMD or AMD+AMD > platform which has the same HW configuration. > > 1.if dGPU has no audio codec. the issue should be always observed. > 2.if both iGPU and dGPU has audio codecs, the issue should be random, > it depends on the first audio found by vgaswitchroo driver is on iGPU > or dGPU. On discrete AMD and Nvidia GPUs, the HDA controller is function 1 and the GPU is function 0 in the same PCI slot. On Intel chipsets, the HDA controller and the GPU have completely different PCI device numbers, e.g. the GPU might be 0000:00:02.0 and the HDA controller might be 0000:00:1b.0. get_bound_vga() checks that the HDA controller is function 1 and there's a GPU in function 0 of the same slot. Thus get_bound_vga() always returns NULL for an Intel HDA controller and the controller is never registered with vga_switcheroo (which is fine). Thanks, Lukas

The patch ASoC: pxa: provide PCM ops for ssp, i2s and ac97 components has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.

Please explain what you mean by UMA here. Are you referring to dual GPU systems where both GPUs are by AMD? And the integrated GPU is incorrectly assigned VGA_SWITCHEROO_DIS? Starting with v4.17, the only reason the audio driver registers with vga_switcheroo is because it can be powered down if manual power control is used. However manual power control is not the default, it's primary use case nowadays is MacBook Pros, and there are no MacBook Pros with dual AMD GPUs. So I don't understand what real world use case you're trying to fix. Please explain. > > Newer dGPUs use PCI_CLASS_DISPLAY_OTHER rather than > > PCI_CLASS_DISPLAY_VGA. Make sure we check for both when > > checking for the dGPU in get_bound_vga() Unlike the other changes in your patch, this one would seem perfectly valid to me. However it's a separate issue, so please put it in a separate patch. Instead of adding a check for PCI_CLASS_DISPLAY_OTHER, I'd prefer you replacing the existing check for PCI_CLASS_DISPLAY_VGA with a check for PCI_BASE_CLASS_DISPLAY, like so: - if ((p->class >> 8) == PCI_CLASS_DISPLAY_VGA) + if ((p->class >> 16) == PCI_BASE_CLASS_DISPLAY) Thanks, Lukas

[alsa-devel] Driver for Maxim MAX9744 Stereo Amplifier
by Tom Rinehart 29 Jun '18

29 Jun '18

I am trying to develop a driver the the Maxim MAX9744 20W Class D Stereo Amplifier. (see https://www.maximintegrated.com/en/products/analog/audio/MAX9744.html <https://www.maximintegrated.com/en/products/analog/audio/MAX9744.html>). It is very similar to the MAX9768 10W Class D Mono amplifier which has a linux driver. (see https://www.maximintegrated.com/en/products/analog/audio/MAX9768.html <https://www.maximintegrated.com/en/products/analog/audio/MAX9768.html>) From a control perspective, both look to be the same from their data sheets. Volume is controlled through i2c, and it has mute and shutdown controlled through gpio. The MAX9744 has a volume control that changes both channels together. When I try to use the MAX9768 driver it shows up as a mono amplifier in alsamixer. What do I need to change in the driver to have it recognize stereo input and output but with the volume control tied together (not independent for each channel)? It seems like I should be able to modify the MAX9768 driver to work with the MAX9744. I have an Adafruit board with the MAX9744 amplifier on it so it is easy to test: https://www.adafruit.com/product/1752 <https://www.adafruit.com/product/1752>.

[alsa-devel] [PATCH] ASoC: pxa: remove the dmaengine compat need

From: Robert Jarzmik <robert.jarzmik(a)free.fr> As the pxa architecture switched towards the dmaengine slave map, the old compatibility mechanism to acquire the dma requestor line number and priority are not needed anymore.

[alsa-devel] [PATCH v3 00/14] ARM: pxa: switch to DMA slave maps

As I gathered almost all the required acks, this is an information only post before queuing to the PXA tree. The only missing part is for netdev, for which I'd like an ack from netdev people for patches 0007 and 0008, but that won't prevent me from queuing all the other patches (excepting the patch 0012 which can only be applied once 0007 and 0008 are queued).

[alsa-devel] [PATCH v2] ASoC: dpcm: improve runtime update predictability
by Jerome Brunet 28 Jun '18

28 Jun '18

As it is, dpcm_runtime_update() performs the old path and new path update of a frontend before going on to the next frontend DAI. Depending the order of the FEs within the rtd list, the result of the update might be different. For example: * Frontend A connected to backend C, with a 48kHz playback * Frontend B connected to backend D, with a 44.1kHz playback * FE A appears before FE B in the rtd list of the card. If we reparent BE C to FE B (disconnecting BE D): * old path update of FE A will run first, and BE C will get hw_free() and shutdown() * new path update of FE B will run after and BE C, which is stopped, so it will be configured at 44.1kHz, as expected If we reparent BE D to FE A (disconnecting BE C): * new path update of FE A will run first but since BE D is still running at 44.1kHz, it won't be reconfigured (no call to startup() or hw_params()) * old path update of FE B runs after, nothing happens * In this case, we end up with a BE playing at 44.1kHz a stream which is supposed to be played at 48Khz (too slow) To improve this situation, this patch performs all the FE old paths update before going on to update the new paths. With this, the result should no longer depend on the order of the FE within the card rtd list. Please note that there might be a small performance penalty since dpcm_process_paths() is called twice per stream direction.

[alsa-devel] [PATCH] ASoC: dpcm: don't merge format from invalid codec dai
by Jerome Brunet 28 Jun '18

28 Jun '18

When merging codec formats, dpcm_runtime_base_format() should skip the codecs which are not supporting the current stream direction. At the moment, if a BE link has more than one codec, and only one of these codecs has no capture DAI, it becomes impossible to start a capture stream because the merged format would be 0. Skipping invalid codec DAI solves the problem.

[alsa-devel] [PATCH v2] ALSA: hda/hdmi - Don't fall back to generic when i915 binding fails
by Takashi Iwai 28 Jun '18

28 Jun '18

When i915 component binding fails, it means that HDMI isn't applicable anyway. Although the probe with the generic HDMI parser would still work, it's essentially useless, hence better to be left unbound. This patch mimics the probe_id field at failing the i915 component binding so that the generic HDMI won't be bound after that.

[alsa-devel] [[PATCH 0/9] ASoC: Intel: bytcr_rt5651: Cleanup (input mapping quirks)
by Hans de Goede 27 Jun '18

27 Jun '18

Hi Mark, This series is mainly a cleanup series. In the beginning of the rt5651 machine driver some wrong assumptions were made, such as the headset mic being attached to IN2 (it is on IN3 on the 7 machines I have access to and on all otherwise known machines). And also adding a quirk for a machine with the intmic on IN2, which later got fixed with a new quirk for machines with 2 internal mics on both IN1 and IN2 and moving the one machine with the IN2 quirk over to the new IN1_IN2 quirk, leaving the IN2 quirk as an orphan quirk for non existing hardware. Then I made a similar mistake adding the IN2_HS_IN3 quirk, while I should have used the IN1_HS_IN3 (which itself only exists because the original IN1 quirk has the headset input mapping wrong), TL;DR: it is a bit of a mess due to a number of wrong assumptions about how the inputs where actually routed in the past. This series cleans this all up in small commits / one bit a time and refers the original commit messages in its commit messages. Note patch 10/11 is not a cleanup patch, but is more or less the reason I took a second look at all the quirks. Regards, Hans

[alsa-devel] [PATCH] ASoC: Intel: Power down links before turning off display audio power
by Sriram Periyasamy 27 Jun '18

27 Jun '18

On certain platforms, Display HDMI HDA codec was not going to sleep state after the use when links are powered down after turning off the display power. As per the HW recommendation, links are powered down before turning off the display power to ensure that the codec goes to sleep state.

[alsa-devel] ASoC: new ac97 bus and codec clock
by Robert Jarzmik 27 Jun '18

27 Jun '18

Hi Mark, The new ac97 is working well in a platform data build. But in the device tree case, there is an issue, triggered by our review in [1]. The main issue is the lack of one clock. The device hierarchy is : - platform device sound@40500000 (the AC97 controller) \-> ac97 device sound@40500000:0 (the discovered ac97 IP for a wm9713) Now the issue is here : - sound/ac97/bus.c:419, function ac97_get_enable_clk() - the clk_get() fails The sound@40500000:0 device was automatically created by the AC97 bus code, but I don't see any way to provide this device the "ac97_clk" ... How do you think this is supposed to work, and how can my devicetree description provide this clock ? -- Robert [1] Discussion reference https://groups.google.com/forum/#!msg/linux.kernel/6_zIXK_maA4/RMYsmLlRMgAJ Look for "You probably mean the BITCLK clock." [2] Device tree extract ac97: sound@40500000 { compatible = "marvell,pxa270-ac97"; reg = < 0x40500000 0x1000 >; interrupts = <14>; reset-gpios = <&gpio 95 GPIO_ACTIVE_HIGH>; #sound-dai-cells = <1>; pinctrl-names = "default"; pinctrl-0 = < &pinctrl_ac97_default >; clocks = <&clks CLK_AC97>, <&clks CLK_AC97CONF>; clock-names = "AC97CLK", "AC97CONFCLK"; };

[alsa-devel] [PATCH] ALSA: hda - Kill snd_hda_codec_update_cache()

snd_hda_codec_update_cache() used to serve for a slightly different purpose from snd_hdac_write_cache(), but now both of them became identical.

Hello. I'm writing plugin with external filter plugin SDK, they make some manipulation on received samples. But i can't use dsd formats. As i understand, they not allowed in all plugins (extplug, ioplug and internal alsa-lib)? params_any + params_test_format(... dsd_u32_le) = error -22 Is this a ALSA lib restriction or i do something wrong Thanks

[alsa-devel] [PATCH 0/4] Fix a broken/missing documentation at sound
by Mauro Carvalho Chehab 26 Jun '18

26 Jun '18

After running ./scripts/documentation-file-ref-check I noticed that it was complaining about the lack of a MultiSound file that used to be inside the old OSS sound system. That's actually a script, with seems to be needed in order to make the multisound driver to work. Also, it contains some instructions about how to use the module. Granted, this is old ISA stuff, but, as long as the driver remains in Kernel, it probably makes sense to keep the script somewhere. So, this patch restores the file from the git log, moving it to an existing directory and updates the module names. It also fixes the script, as it has some issues that prevents it to work with modern distributions (basically, include stuff at C files it produces). - Please notice that I don't have such hardware to test. So, I have no means to know if the produced exec file still makes sense.

[alsa-devel] [PATCH 1/2] ASoC: add generic simple-amplifier support
by Nicolò Veronese 26 Jun '18

26 Jun '18

Many boards have speaker amplifier attached on an analog output. Most of them are only managed by a mute or shutdown GPIO. In order to reduce duplicate driver, this patch adds generic/simple-amplifier.

[alsa-devel] [PATCH v6 0/3] ASoC: Add Multi CPU DAI support
by Shreyas NC 26 Jun '18

26 Jun '18

As discussed in [1], ASoC core supports multi codec DAIs on a DAI link. However it does not do so for CPU DAIs. So, add support for multi CPU DAIs on a DAI Link by adding multi CPU DAI in Card instantiation, suspend and resume functions, PCM ops, stream handling functions and DAPM. [1]: https://www.spinics.net/lists/alsa-devel/msg71369.html changes in v6: - Addressed review comments from Pierre in calculating delay for CPU DAI, add check for compress DAIs and other nits - add proper exit check in dpcm_prune_path() for CPU DAIs - rebased on latest for-next branch Shreyas NC (3): ASoC: Add initial support for multiple CPU DAIs ASoC: Add multiple CPU DAI support for PCM ops ASoC: Add multiple CPU DAI support in DAPM include/sound/soc.h | 6 + sound/soc/soc-core.c | 290 +++++++++++++++++++++--------- sound/soc/soc-dapm.c | 71 +++++--- sound/soc/soc-pcm.c | 491 ++++++++++++++++++++++++++++++++++----------------- 4 files changed, 589 insertions(+), 269 deletions(-) -- 2.7.4

[alsa-devel] [PATCH 0/2] slimbus: Add Stream Support
by Srinivas Kandagatla 25 Jun '18

25 Jun '18

This patchset adds basic stream support for SLIMbus devices and controllers. Mostly inspired by soundwire stream patches. But slimbus stream is much simpler compared to soundwire >From slim_device side, we have below 6 new apis. slim_stream_allocate() - allocating runtime slim stream slim_stream_prepare() - to configure runtime stream with config slim_stream_enable() - enable channels/ports for data slim_stream_disable() - disable channels/ports. slim_stream_unprepare() - un configure runtime stream slim_stream_free() - free all associated memory. >From Controller side: Data channel Management and reconfiguration messages are applicable for all the controllers which are inline with SLIMbus specs. However light weight controller like NGD which have user specific implementation of some messages need to be invoked instead of standard message commands. For usecases like this simple enable/disable stream apis are provided. Assumptions: 1> Current design assumes that the channel and ports are statically allocated to the device during SoC integration, which is the case with all the Qualcomm SoCs. 2> One-to-One mapping between Port and Channel, SLIMBus versions earlier than 2.0 has only one endpoint per port. Current patchset can be extended to support more than one endpoints per port. 3> Only audio usecase, This patchset only supports Isochronous and Push/Pull transport protocols, which are sufficient for audio use cases. 4> DSP does all the data handling for the allocated channels. Which is true for Qcom SoCs. TODO: Bandwidth management. Dependency: This patchset has dependency on the NGD driver https://patchwork.kernel.org/patch/10474959/ Tested this patchset with WCD9335 codec playback on DB820c on top of 4.18-rc1 with qdsp6. I have pushed my working branch to [1] incase someone want to try.

[alsa-devel] first and last audio sample timestamp
by Subhashini Rao Beerisetty 25 Jun '18

25 Jun '18

[ Please keep me in CC as I'm not subscribed to the list] Hi All, Hello all, I’m using aplay and arecord utilities for playback and capture. I need to capture the timestamps for the first and last audio samples that arrive at the driver level. For this I’m capturing the CLOCK_MONOTONIC_RAW timestamp at the .trigger(for playback & capture) callback in SNDRV_PCM_TRIGGER_START case – is it the correct timestamp for the first audio sample arrived at the driver level? Similarly does .trigger callbacks SNDRV_PCM_TRIGGER_STOP gives the last audio sample timestamp?

[alsa-devel] [PATCH] ASoC: dpcm: improve runtime update predictability
by Jerome Brunet 25 Jun '18

25 Jun '18

As it is, dpcm_runtime_update() performs the old path and new path update of a frontend before going on to the next frontend DAI. Depending the order of the FEs within the rtd list, the result of the update might be different. For example: * Frontend A connected to backend C, with a 48kHz playback * Frontend B connected to backend D, with a 44.1kHz playback * FE A appears before FE B in the rtd list of the card. If we reparent BE C to FE B (disconnecting BE D): * old path update of FE A will run first, and BE C will get hw_free() and shutdown() * new path update of FE B will run after and BE C, which is stopped, so it will be configured at 44.1kHz, as expected If we reparent BE D to FE A (disconnecting BE C): * new path update of FE A will run first but since BE D is still running at 44.1kHz, it won't be reconfigured (no call to startup() or hw_params()) * old path update of FE B runs after, nothing happens * In this case, we end up with a BE playing at 44.1kHz a stream which is supposed to be played at 48Khz (too slow) To improve this situation, this patch performs all the FE old paths update before going on to update the new paths. With this, the result should no longer depend on the order of the FE within the card rtd list. Please note that there might be a small performance penalty since dpcm_process_paths() is called twice per stream direction.

[alsa-devel] [PATCH] ASoC: cx20442: Don't ignore regulator_get() errors.
by Janusz Krzysztofik 25 Jun '18

25 Jun '18

In its current shape, the driver just ignores errors returned by regulator_get() at component_probe(). This doesn't hurt on Amstrad Delta board as long as it registers the codec device at late_initcall, when the regulator which depends on basic-mmio-gpio device (probed as late as at dev_initcall) is already available. Otherwise the driver may end up trying to control a codec which is not powered up. Remove that dependency on initialization order by handling the error. If the regulator is not yet available and -ENODEV is returned, convert it to -EPROBE_DEFER to get another chance.

[alsa-devel] [PATCH 0/3] ASoC: make simple-card a bit more versatile
by Daniel Mack 25 Jun '18

25 Jun '18

In the process of porting some boards to DT, I noticed the simple-card driver is already capable of handling most cases just fine. The missing bits I've spotted are: * The clock that is passed in is only read, never set, which is not sufficient for boards that support several sampling rates with different base frequencies * The sysclk id that is passed to snd_soc_dai_set_sysclk() is hard-coded * There's currently no support for calling into snd_soc_dai_set_clkdiv() The following three patches fix all those and make simple-card a good match for the board I'm working with. Thanks, Daniel Daniel Mack (3): ASoC: simple-card: set cpu dai clk in hw_params ASoC: simple-card: make sysclk index configurable ASoC: simple-card: add support for clock divider setup .../devicetree/bindings/sound/simple-card.txt | 13 ++++++ include/sound/simple_card_utils.h | 19 ++++++++ sound/soc/generic/simple-card-utils.c | 50 ++++++++++++++++++++++ sound/soc/generic/simple-card.c | 49 +++++++++++++++++++-- 4 files changed, 127 insertions(+), 4 deletions(-) -- 2.14.3

[alsa-devel] [PATCH 1/2] ASoC: rt5651: Add support for external amplifier enable GPIO
by Hans de Goede 25 Jun '18

25 Jun '18

The rt5651 does not have a built-in speaker amplifier, so it is often used together with an external amplifier. On some boards the external amplifier's enable pin is driven through a GPIO, add support for this.

[alsa-devel] audio samples data flow from user mode to kernel mode
by Subhashini Rao Beerisetty 25 Jun '18

25 Jun '18

Hello All, I’m trying to understand how audio samples transferred between user mode to kernel mode during playback and capture. I’m using aplay & arecord alsa utilities for playback and capture. Let us take a PCM wav file of sample rate 48000 and it has a total number of samples 480000 (Approx.Duration in seconds=10). Size of each sample is 8 bytes(two channels). After invocation of aplay from user mode, how does these audio samples gets copied to kernel mode? Can someone explain me on this? Is it possible to capture the timestamps for the first and last audio samples that arrive at the driver level? Can I consider the .trigger(for playback & capture) callback in SNDRV_PCM_TRIGGER_START case is timestamp for the first audio sample? Similarly does .trigger callbacks SNDRV_PCM_TRIGGER_STOP gives the last audio sample timestamp? Thanks,

[alsa-devel] [PATCH] ALSA: hda/realtek - Fix the problem of two front mics on more machines
by Hui Wang 25 Jun '18

25 Jun '18

We have 3 more Lenovo machines, they all have 2 front mics on them, so they need the fixup to change the location for one of two mics. Among these 3 Lenovo machines, one of them has the same pin cfg as the machine with subid 0x17aa3138, so use the pin cfg table to apply fixup for them. The rest machines don't share the same pin cfg, so far use the subid to apply fixup for them.

[alsa-devel] ALSA: use irqsave() in URB completion + usb_fill_int_urb
by Sebastian Andrzej Siewior 22 Jun '18

22 Jun '18

This series is mostly about using _irqsave() primitives in the completion callback in order to get rid of local_irq_save() in __usb_hcd_giveback_urb(). While at it, I also tried to move drivers to use usb_fill_int_urb() otherwise it is hard find users of a certain API. Sebastian

[alsa-devel] [PATCH] ALSA: hda/realtek - Apply PRE_PROBE fixup after ALC269 codec variant setups
by Takashi Iwai 22 Jun '18

22 Jun '18

Currently patch_alc269() calls the fixup with HDA_FIXUP_ACT_PRE_PROBE before setting up the codec model-specific setups (e.g. setting codec_variant or mixer_nid setup). This is rather confusing as others do call the *_PRE_PROBE fixup after such a setup. Due to this disorder, we have to override spec->shutup not at the usual HDA_FIXUP_ACT_PRE_PROBE but the unusual HDA_FIXUP_ACT_PROBE time. This patch corrects the fixup call orders in patch_alc269(), and also corrects the action to set up spec->shutup accordingly. No functional changes but just refactoring.
