[RESEND PATCH 0/1] ALSA: virtio: add support for audio controls
by Aiswarya Cyriac 15 Jan '24

15 Jan '24

From: Anton Yakovlev <anton.yakovlev(a)opensynergy.com> Implementation of support for audio controls in accordance with the extension of the virtio sound device specification[1] planned for virtio-v1.3-cs01. Design　of virtual audio controls is based on and derived from ALSA audio controls. It allows the driver to perform all standard operations, such as reading and writing audio control value, as well as working with metadata (represented in the TLV form). The driver part was tested on top of the Linux 5.10 kernel. As a device part was used OpenSynergy proprietary implementation.

Yamaha YIT-W12TX not working
by Julian Sikorski 27 Nov '23

27 Nov '23

Hi list, Yamaha YIT-W12TX is a USB dongle which allows to transmit audio from PC to the YSP-4300 sound bar [1][2]. While it is quite old and no longer sold, I recently tried to make it work under linux. Unfortunately, it did not work: [ 3676.366404] usb 2-1.1: new full-speed USB device number 5 using ehci-pci [ 3676.445995] usb 2-1.1: config 1 has an invalid interface number: 4 but max is 3 [ 3676.446001] usb 2-1.1: config 1 has no interface number 2 [ 3676.446664] usb 2-1.1: New USB device found, idVendor=0499, idProduct=3108, bcdDevice= 1.00 [ 3676.446666] usb 2-1.1: New USB device strings: Mfr=2, Product=1, SerialNumber=0 [ 3676.446679] usb 2-1.1: Product: YIT-W12TX [ 3676.446683] usb 2-1.1: Manufacturer: YAMAHA Corp.

Re: RFC: usb: gadget: u_audio: Notifying gadget that host started playback/capture?

Hi, Dne 08. 09. 21 v 10:21 Pavel Hofman napsal(a): > Hi, > > The current audio gadget has no way to inform the gadget side that the > host side has started playback/capture and that gadget-side alsa > processes should be started. > > Playback/capture processes on the host side do not get stuck without the > gadget side consuming/producing data (OUT requests are ignored in > u_audio_iso_complete, IN ones send initial zeros in their req->buf). > > However, playback/capture processes on the gadget side get stuck without > the host side sending playback OUT packets or capture IN requests and > time out with error.

Their values are set/reset in methods u_audio_start_capture/playback and u_audio_stop_capture/playback, i.e. at changes of respective altsettings from 0 to 1 and back. Every ctl elem value change sends notification via snd_ctl_notify. The principle works OK for capture/playback start/stop on the host, as monitored by alsactl: pi@raspberrypi:~ $ alsactl monitor hw:UAC2Gadget node hw:UAC2Gadget, #4 (3,0,0,Capture Requested,0) VALUE node hw:UAC2Gadget, #4 (3,0,0,Capture Requested,0) VALUE node hw:UAC2Gadget, #3 (3,0,0,Playback Requested,0) VALUE node hw:UAC2Gadget, #3 (3,0,0,Playback Requested,0) VALUE However at enumeration the USB host switches both playback and capture altsettings repeatedly, generating "fake" events from the gadget side POW. The host even sends regular-sized EP-OUT packets filled with zeros during enumeration (tested on linux only for now). Please is there any way to "detect" the enumeration stage to mask out the "fake" playback/capture start/stop events? The attached patch does not apply cleanly to mainline u_audio.c because it's rebased on other patches not submitted yet but it's only a discussion inducer for now. Thanks a lot, Pavel.

Takashi, can you please further explain why asym is not the solution and what you see as a problem? I am also trying to figure out if it would be possible to create such a plugin for ALSA? I am still searching for some good starting points on how to write an ALSA plugin... Jean-Marc Valin (http://lists.linuxaudio.org/pipermail/linux-audio-dev/2005-June/012454.html) already released his work as part of speex but as far I know there is no plugin that has been made out of it?

[PATCH v3 0/6] Introduce STM32 system bus
by Gatien Chevallier 05 Jul '23

05 Jul '23

Document STM32 System Bus. This bus is intended to control firewall access for the peripherals connected to it. For every peripheral, the bus checks the firewall registers to see if the peripheral is configured as non-secure. If the peripheral is configured as secure, the node is marked populated, so the device won't be probed. This is useful as a firewall configuration sanity check and avoid platform crashes in case peripherals are incorrectly configured. The STM32 System Bus implements the feature-domain-controller bindings. It is used by peripherals to reference a domain controller, in this case the firewall feature domain. The bus uses the ID referenced by the feature-domains property to know where to look in the firewall to get the security configuration for the peripheral. This allows a device tree description rather than a hardcoded peripheral table in the bus driver. On STM32MP13/15 platforms, the firewall bus is represented by the ETZPC node, which is responsible for the securing / MCU isolating the capable peripherals. STM32MP13/15 device trees are updated in this series to implement the bus. All peripherals that are securable or MCU isolation capable by the ETZPC are connected to the bus. Changes in V2: - Corrected YAMLS errors highlighted by Rob's robot - Re-ordered Signed-off-by tags in two patches Changes in V3: - Document feature-domains property in YAML documentation for concerned periperals under the System Bus - Fix STM32 System Bus YAML documentation - Remove STM32 System bus bindings that were currently used as helpers for device tree - Correct few errors in driver - Add missing peripherals under the System Bus that were in SoC variation device tree files - Fix node names Gatien Chevallier (5): dt-bindings: treewide: add feature-domains description in binding files dt-bindings: bus: add STM32 System Bus bus: stm32_sys_bus: add support for STM32MP15 and STM32MP13 system bus ARM: dts: stm32: add ETZPC as a system bus for STM32MP15x boards ARM: dts: stm32: add ETZPC as a system bus for STM32MP13x boards Oleksii Moisieiev (1): dt-bindings: Document common device controller bindings .../devicetree/bindings/bus/st,sys-bus.yaml | 127 + .../bindings/crypto/st,stm32-hash.yaml | 5 + .../devicetree/bindings/dma/st,stm32-dma.yaml | 5 + .../bindings/dma/st,stm32-dmamux.yaml | 5 + .../feature-domain-controller.yaml | 84 + .../devicetree/bindings/i2c/st,stm32-i2c.yaml | 5 + .../bindings/iio/adc/st,stm32-adc.yaml | 5 + .../bindings/iio/adc/st,stm32-dfsdm-adc.yaml | 5 + .../bindings/iio/dac/st,stm32-dac.yaml | 5 + .../bindings/media/st,stm32-cec.yaml | 5 + .../bindings/media/st,stm32-dcmi.yaml | 5 + .../memory-controllers/st,stm32-fmc2-ebi.yaml | 5 + .../bindings/mfd/st,stm32-lptimer.yaml | 5 + .../bindings/mfd/st,stm32-timers.yaml | 6 + .../devicetree/bindings/mmc/arm,pl18x.yaml | 5 + .../devicetree/bindings/net/stm32-dwmac.yaml | 5 + .../bindings/phy/phy-stm32-usbphyc.yaml | 5 + .../bindings/regulator/st,stm32-vrefbuf.yaml | 5 + .../devicetree/bindings/rng/st,stm32-rng.yaml | 5 + .../bindings/serial/st,stm32-uart.yaml | 5 + .../bindings/sound/st,stm32-i2s.yaml | 5 + .../bindings/sound/st,stm32-sai.yaml | 5 + .../bindings/sound/st,stm32-spdifrx.yaml | 5 + .../bindings/spi/st,stm32-qspi.yaml | 5 + .../devicetree/bindings/spi/st,stm32-spi.yaml | 5 + .../devicetree/bindings/usb/dwc2.yaml | 5 + MAINTAINERS | 6 + arch/arm/boot/dts/stm32mp131.dtsi | 407 +-- arch/arm/boot/dts/stm32mp133.dtsi | 51 +- arch/arm/boot/dts/stm32mp13xc.dtsi | 19 +- arch/arm/boot/dts/stm32mp13xf.dtsi | 18 +- arch/arm/boot/dts/stm32mp151.dtsi | 2722 +++++++++-------- arch/arm/boot/dts/stm32mp153.dtsi | 52 +- arch/arm/boot/dts/stm32mp15xc.dtsi | 19 +- drivers/bus/Kconfig | 9 + drivers/bus/Makefile | 1 + drivers/bus/stm32_sys_bus.c | 168 + 37 files changed, 2208 insertions(+), 1596 deletions(-) create mode 100644 Documentation/devicetree/bindings/bus/st,sys-bus.yaml create mode 100644 Documentation/devicetree/bindings/feature-controllers/feature-domain-controller.yaml create mode 100644 drivers/bus/stm32_sys_bus.c -- 2.35.3

[PATCH 1/2] ASoC: fsl-asoc-card: add nau8822 support
by Hui Wang 23 Jun '23

23 Jun '23

This is for an imx6sx EVB which has a nau8822 codec connects to the SSI2 interface, so add the nau8822 support in this machine driver. Because the codec driver nau8822.c doesn't handle mclk enabling, here adding a codec_priv->mclk for nau8822 and similar codecs which need to enable the mclk in the machine driver, and enable the mclk in the card_late_probe() conditionally.

[regression] Bug 216818 - The microphone mute led not working after linux 6
by Thorsten Leemhuis 20 Jun '23

20 Jun '23

Hi, this is your Linux kernel regression tracker speaking. I noticed a regression report in bugzilla.kernel.org. As many (most?) kernel developer don't keep an eye on it, I decided to forward it by mail. Quoting from https://bugzilla.kernel.org/show_bug.cgi?id=216818 : > sonic82003(a)gmail.com 2022-12-18 08:52:32 UTC > > The mic mute led of my ThinkPad X1 Carbon Gen 9 doesn't work anymore after updating linux to version 6. > I can still turn it on by running > > echo 1 > /sys/class/leds/platform::micmute/brightness > > With linux-lts it still works fine. See the ticket for more details. Note, I found a similar report that (despite my attempts to prevent things like this from happening) fell through the cracks here: https://bugzilla.kernel.org/show_bug.cgi?id=216355 > plum 2022-08-13 02:11:01 UTC > > I upgrade to kernel 5.19.1 but found my thinkpad x1 carbon 2021's mute led stop working. > > Function is okay but LED won't light up. > > Back to kernel 5.18 and it's normal and working again. > > Fedora 36 64 bit > Gnome-shell 42 >From a quick research it looks to me like this is an issue for the sounds maintainers, as the LED itself apparently works. If that is something for the platform people instead please speak up. BTW, let me use this mail to also add the report to the list of tracked regressions to ensure it's doesn't fall through the cracks: #regzbot introduced: v5.18..v5.19 https://bugzilla.kernel.org/show_bug.cgi?id=216818 #regzbot ignore-activity Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) P.S.: As the Linux kernel's regression tracker I deal with a lot of reports and sometimes miss something important when writing mails like this. If that's the case here, don't hesitate to tell me in a public reply, it's in everyone's interest to set the public record straight.

[PATCH] kselftest/alsa: Increase kselftest timeout
by Nícolas F. R. A. Prado 16 Jun '23

16 Jun '23

The default timeout for kselftests is 45 seconds, but pcm-test can take longer than that to run depending on the number of PCMs present on a device. As a data point, running pcm-test on mt8192-asurada-spherion takes about 1m15s. Set the timeout to 10 minutes, which should give enough slack to run the test even on devices with many PCMs. Signed-off-by: Nícolas F. R. A.

[PATCH v2 00/65] clk: Make determine_rate mandatory for muxes
by Maxime Ripard 05 Apr '23

05 Apr '23

Hi, This is a follow-up to a previous series that was printing a warning when a mux has a set_parent implementation but is missing determine_rate(). The rationale is that set_parent() is very likely to be useful when changing the rate, but it's determine_rate() that takes the parenting decision. If we're missing it, then the current parent is always going to be used, and thus set_parent() will not be used. The only exception being a direct call to clk_set_parent(), but those are fairly rare compared to clk_set_rate(). Stephen then asked to promote the warning to an error, and to fix up all the muxes that are in that situation first. So here it is :) Let me know what you think, Maxime To: Michael Turquette <mturquette(a)baylibre.com> To: Stephen Boyd <sboyd(a)kernel.org> To: Andreas Färber <afaerber(a)suse.de> To: Manivannan
