04 May '24

alsa-project/alsa-python pull request #10 was opened from FrancescoCeruti: This fixes (#9) a segmentation fault that started happening with python 3.12, changes in the PyLongObject implementation have broken some pointer arithmetic, which, from what I understand, is not necessary. Probably someone with a better understanding of C should check this :) I've tested with 3.12, 3.11 and 3.7.

[PATCH] ALSA: hda/cs_dsp_ctl: Actually remove ALSA controls
by Richard Fitzgerald 03 May '24

03 May '24

hda_cs_dsp_control_remove() must remove the ALSA control when deleting all the infrastructure for handling the control. Without this it is possible for ALSA controls to be left in the Soundcard after the amp driver module has been unloaded. So the get/set callbacks point to code that no longer exists.

But that is a larger change to the code. I like to keep bugfix patches as simple as possible so they are low-risk and easy to cherry-pick into older kernels. So this patch fixes the bug. Sometime I will send a patch for future kernel versions that reworks the cleanup to use private_free. --- sound/pci/hda/hda_cs_dsp_ctl.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/sound/pci/hda/hda_cs_dsp_ctl.c b/sound/pci/hda/hda_cs_dsp_ctl.c index 463ca06036bf..a42653d3473d 100644 --- a/sound/pci/hda/hda_cs_dsp_ctl.c +++ b/sound/pci/hda/hda_cs_dsp_ctl.c @@ -203,6 +203,10 @@ void hda_cs_dsp_control_remove(struct cs_dsp_coeff_ctl *cs_ctl) { struct hda_cs_dsp_coeff_ctl *ctl = cs_ctl->priv; + /* Only public firmware controls will have an associated kcontrol */ + if (ctl && ctl->kctl) + snd_ctl_remove(ctl->card, ctl->kctl); + kfree(ctl); } EXPORT_SYMBOL_NS_GPL(hda_cs_dsp_control_remove, SND_HDA_CS_DSP_CONTROLS); -- 2.39.2

[PATCH V2 1/2] ASoC: amd: acp: fix for acp platform device creation failure
by Vijendar Mukunda 03 May '24

03 May '24

ACP pin configuration varies based on acp version. ACP PCI driver should read the ACP PIN config value and based on config value, it has to create a platform device in below two conditions. 1) If ACP PDM configuration is selected from BIOS and ACP PDM controller exists. 2) If ACP I2S configuration is selected from BIOS. Other than above scenarios, ACP PCI driver should skip the platform device creation logic, i.e. ACP PCI driver probe sequence should never fail if other acp pin configuration is selected. It should skip platform device creation logic. check_acp_pdm() function was implemented for ACP6.x platforms to check ACP PDM configuration. Previously, this code was safe guarded by FLAG_AMD_LEGACY_ONLY_DMIC flag check. This implementation breaks audio use cases for Huawei Matebooks which are based on ACP3.x varaint uses I2S configuration. In current scenario, check_acp_pdm() function returns -ENODEV value which results in ACP PCI driver probe failure without creating a platform device even in case of valid ACP pin configuration. Implement check_acp_config() as a common function which invokes platform specific acp pin configuration check functions for ACP3.x, ACP6.0 & ACP6.3 & ACP7.0 variants and checks for ACP PDM controller.

[PATCH v20 00/41] Introduce QC USB SND audio offloading support
by Wesley Cheng 03 May '24

03 May '24

Several Qualcomm based chipsets can support USB audio offloading to a dedicated audio DSP, which can take over issuing transfers to the USB host controller. The intention is to reduce the load on the main processors in the SoC, and allow them to be placed into lower power modes. There are several parts to this design: 1. Adding ASoC binding layer 2. Create a USB backend for Q6DSP 3. Introduce XHCI interrupter support 4. Create vendor ops for the USB SND driver USB | ASoC -------------------------------------------------------------------- | _________________________ | |sm8250 platform card | | |_________________________| | | | | ___V____ ____V____ | |Q6USB | |Q6AFE | | |"codec" | |"cpu" | | |________| |_________| | ^ ^ ^ | | |________| | ___V____ | | |SOC-USB | | ________ ________ | | | |USB SND |<--->|QC offld|<------------>|________| | |(card.c)| | |<---------- | |________| |________|___ | | | ^ ^ | | | ____________V_________ | | | | | |APR/GLINK | __ V_______________V_____ | | | |______________________| |USB SND (endpoint.c) | | | | ^ |_________________________| | | | | ^ | | | ___________V___________ | | | |->|audio DSP | ___________V_____________ | | |_______________________| |XHCI HCD |<- | |_________________________| | Adding ASoC binding layer: soc-usb: Intention is to treat a USB port similar to a headphone jack. The port is always present on the device, but cable/pin status can be enabled/disabled. Expose mechanisms for USB backend ASoC drivers to communicate with USB SND. Create a USB backend for Q6DSP: q6usb: Basic backend driver that will be responsible for maintaining the resources needed to initiate a playback stream using the Q6DSP. Will be the entity that checks to make sure the connected USB audio device supports the requested PCM format. If it does not, the PCM open call will fail, and userpsace ALSA can take action accordingly. Introduce XHCI interrupter support: XHCI HCD supports multiple interrupters, which allows for events to be routed to different event rings. This is determined by "Interrupter Target" field specified in Section "6.4.1.1 Normal TRB" of the XHCI specification. Events in the offloading case will be routed to an event ring that is assigned to the audio DSP. Create vendor ops for the USB SND driver: qc_audio_offload: This particular driver has several components associated with it: - QMI stream request handler - XHCI interrupter and resource management - audio DSP memory management When the audio DSP wants to enable a playback stream, the request is first received by the ASoC platform sound card. Depending on the selected route, ASoC will bring up the individual DAIs in the path. The Q6USB backend DAI will send an AFE port start command (with enabling the USB playback path), and the audio DSP will handle the request accordingly. Part of the AFE USB port start handling will have an exchange of control messages using the QMI protocol. The qc_audio_offload driver will populate the buffer information: - Event ring base address - EP transfer ring base address and pass it along to the audio DSP. All endpoint management will now be handed over to the DSP, and the main processor is not involved in transfers. Overall, implementing this feature will still expose separate sound card and PCM devices for both the platorm card and USB audio device: 0 [SM8250MTPWCD938]: sm8250 - SM8250-MTP-WCD9380-WSA8810-VA-D SM8250-MTP-WCD9380-WSA8810-VA-DMIC 1 [Audio ]: USB-Audio - USB Audio Generic USB Audio at usb-xhci-hcd.1.auto-1.4, high speed This is to ensure that userspace ALSA entities can decide which route to take when executing the audio playback. In the above, if card#1 is selected, then USB audio data will take the legacy path over the USB PCM drivers, etc... This feature was validated using: - tinymix: set/enable the multimedia path to route to USB backend - tinyplay: issue playback on platform card Requesting to see if we can get some Acked-By tags, and merge on usb-next. Changelog -------------------------------------------- Changes in v20: - Fixed up some formatting changes pointed out in the usb.rst - Added SB null check during XHCI sideband unregister in case caller passes improper argument (xhci_sideband_unregister()) Changes in v19: - Rebased to usb-next to account for some new changes in dependent drivers. Changes in v18: - Rebased to usb-next, which merged in part of the series. Removed these patches. - Reworked Kconfigs for the ASoC USB related components from QCOM Q6DSP drivers to keep dependencies in place for SoC USB and USB SND. - Removed the repurposing of the stop ep sync API into existing XHCI operations. This will be solely used by the XHCI sideband for now. Changes in v17: - Fixed an issue where one patch was squashed into another. - Re-added some kconfig checks for helpers exposed in USB SND for the soc usb driver, after running different kconfigs. Changes in v16: - Modified some code layer dependencies so that soc usb can be split as a separate module. - Split the kcontrols from ASoC QCOM common layer into a separate driver - Reworked SOC USB kcontrols for controlling card + pcm offload routing and status so that there are individual controls for card and pcm devices. - Added a kcontrol remove API in SOC USB to remove the controls on the fly. This required to add some kcontrol management to SOC USB. - Removed the disconnect work and workqueue for the QC USB offload as it is not required, since QMI interface driver ensures events are handled in its own WQ. Changes in v15: - Removed some already merged XHCI changes - Separated SOC USB driver from being always compiled into SOC core. Now configurable from kconfig. - Fixed up ASoC kcontrol naming to fit guidelines. - Removed some unnecessary dummy ifdefs. - Moved usb snd offload capable kcontrol to be initialized by the platform offloading driver. Changes in v14: - Cleaned up some USB SND related feedback: - Renamed SNDUSB OFFLD playback available --> USB offload capable card - Fixed locking while checking if stream is in use - Replaced some mutex pairs with guard(mutex) Changes in v13: - Pulled in secondary/primary interrupter rework from Mathias from: https://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git/log/drivers… - Did some cleanup and commit message updates, and tested on current code base. - Added mutex locking to xhci sideband to help prevent any race conditions, esp. for when accessing shared references. - Addresed concerns from Hillf about gfp_flags and locking used in qc_usb_audio_offload. - Rebased onto usb-next Changes in v12: - Updated copyright year to 2024. Happy new years! - Fixed newline format on mixer offload driver. Changes in v11: - Modified QMI format structures to be const Changes in v10: - Added new mixer for exposing kcontrol for sound card created by USB SND. This allows for applications to know which platform sound card has offload support. Will return the card number. - Broke down and cleaned up some functions/APIs within qc_audio_offload driver. - Exported xhci_initialize_ring_info(), and modified XHCI makefile to allow for the XHCI sideband to exist as a module. - Reworked the jack registration and moved it to the QCOM platform card driver, ie sm8250. - Added an SOC USB API to fetch a standard component tag that can be appended to the platform sound card. Added this tag to sm8250 if any USB path exists within the DT node. - Moved kcontrols that existed in the Q6USB driver, and made it a bit more generic, so that naming can be standardized across solutions. SOC USB is now responsible for creation of these kcontrols. - Added a SOC USB RST document explaining some code flows and implementation details so that other vendors can utilize the framework. - Addressed a case where USB device connection events are lost if usb offload driver (qc_audio_offload) is not probed when everything else has been initialized, ie USB SND, SOC USB and ASoC sound card. Add a rediscover device call during module init, to ensure that connection events will be propagated. - Rebased to usb-next. Changes in v9: - Fixed the dt binding check issue with regards to num-hc-interrupters. Changes in v8: - Cleaned up snd_soc_usb_find_priv_data() based on Mark's feedback. Removed some of the duplicate looping code that was present on previous patches. Also renamed the API. - Integrated Mathias' suggestions on his new sideband changes: https://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git/log/?h=feat… - Addressed some of Mathias' fixme tags, such as: - Resetting transfer ring dequeue/enqueue pointers - Issuing stop endpoint command during ep removal - Reset ERDP properly to first segment ring during interrupter removal. (this is currently just being cleared to 0, but should be pointing to a valid segment if controller is still running. Changes in v7: - Fixed dt check error for q6usb bindings - Updated q6usb property from qcom,usb-audio-intr-num --> qcom,usb-audio-intr-idx - Removed separate DWC3 HC interrupters num property, and place limits to XHCI one. - Modified xhci_ring_to_sgtable() to use assigned IOVA/DMA address to fetch pages, as it is not ensured event ring allocated is always done in the vmalloc range. Changes in v6: - Fixed limits and description on several DT bindings (XHCI and Q6USB) - Fixed patch subjects to follow other ALSA/ASoC notations. USB SND - Addressed devices which expose multiple audio (UAC) interfaces. These devices will create a single USB sound card with multiple audio streams, and receive multiple interface probe routines. QC offload was not properly considering cases with multiple probe calls. - Renamed offload module name and kconfig to fit within the SND domain. - Renamed attach/detach endpoint API to keep the hw_params notation. Changes in v5: - Removed some unnescessary files that were included - Fixed some typos mentioned - Addressed dt-binding issues and added hc-interrupters definition to usb-xhci.yaml XHCI: - Moved secondary skip events API to xhci-ring and updated implementation - Utilized existing XHCI APIs, such as inc_deq and xhci_update_erst_dequeue() USB SND - Renamed and reworked the APIs in "sound: usb: Export USB SND APIs for modules" patch to include suggestions to utilize snd_usb_hw_params/free and to avoid generic naming. - Added a resume_cb() op for completion sake. - Addressed some locking concerns with regards to when registering for platform hooks. - Added routine to disconnect all offloaded devices during module unbind. ASoC - Replaced individual PCM parameter arguments in snd_soc_usb_connect() with new snd_soc_usb_device structure to pass along PCM info. - Modified snd_jack set report to notify HEADPHONE event, as we do not support record path. Changes in v4: - Rebased to xhci/for-usb-next - Addressed some dt-bindings comments XHCI: - Pulled in latest changes from Mathias' feature_interrupters branch: https://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git/log/?h=feat… - Fixed commit text and signage for the XHCI sideband/interrupter related changes - Added some logic to address the FIXME tags mentioned throughout the commits, such as handling multi segment rings and building the SGT, locking concerns, and ep cleanup operations. - Removed some fixme tags for conditions that may not be needed/addressed. - Repurposed the new endpoint stop sync API to be utilized in other places. - Fixed potential compile issue if XHCI sideband config is not defined. ASoC: - Added sound jack control into the Q6USB driver. Allows for userpsace to know when an offload capable device is connected. USB SND: - Avoided exporting _snd_pcm_hw_param_set based on Takashi's recommendation. - Split USB QMI packet header definitions into a separate commit. This is used to properly allow the QMI interface driver to parse and route QMI packets accordingly - Added a "depends on" entry when enabling QC audio offload to avoid compile time issues. Changes in v3: - Changed prefix from RFC to PATCH - Rebased entire series to usb-next - Updated copyright years XHCI: - Rebased changes on top of XHCI changes merged into usb-next, and only added changes that were still under discussion. - Added change to read in the "num-hc-interrupters" device property. ASoC: - qusb6 USB backend - Incorporated suggestions to fetch iommu information with existing APIs - Added two new sound kcontrols to fetch offload status and offload device selection. - offload status - will return the card and pcm device in use tinymix -D 0 get 1 --> 1, 0 (offload in progress on card#1 pcm#0) - device selection - set the card and pcm device to enable offload on. Ex.: tinymix -D 0 set 1 2 0 --> sets offload on card#2 pcm#0 (this should be the USB card) USB SND: - Fixed up some locking related concerns for registering platform ops. - Moved callbacks under the register_mutex, so that - Modified APIs to properly pass more information about the USB SND device, so that the Q6USB backend can build a device list/map, in order to monitor offload status and device selection. Changes in v2: XHCI: - Replaced XHCI and HCD changes with Mathias' XHCI interrupter changes in his tree: https://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git/log/?h=feat… Adjustments made to Mathias' changes: - Created xhci-intr.h to export/expose interrupter APIs versus exposing xhci.h. Moved dependent structures to this file as well. (so clients can parse out information from "struct xhci_interrupter") - Added some basic locking when requesting interrupters. - Fixed up some sanity checks. - Removed clearing of the ERSTBA during freeing of the interrupter. (pending issue where SMMU fault occurs if DMA addr returned is 64b - TODO) - Clean up pending events in the XHCI secondary interrupter. While testing USB bus suspend, it was seen that on bus resume, the xHCI HC would run into a command timeout. - Added offloading APIs to xHCI to fetch transfer and event ring information. ASoC: - Modified soc-usb to allow for multiple USB port additions. For this to work, the USB offload driver has to have a reference to the USB backend by adding a "usb-soc-be" DT entry to the device saved into XHCI sysdev. - Created separate dt-bindings for defining USB_RX port. - Increased APR timeout to accommodate the situation where the AFE port start command could be delayed due to having to issue a USB bus resume while handling the QMI stream start command. USB SND: - Added a platform ops during usb_audio_suspend(). This allows for the USB offload driver to halt the audio stream when system enters PM suspend. This ensures the audio DSP is not issuing transfers on the USB bus. - Do not override platform ops if they are already populated. - Introduce a shared status variable between the USB offload and USB SND layers, to ensure that only one path is active at a time. If the USB bus is occupied, then userspace is notified that the path is busy.

usb:gadget:f_uac2: RFC: allowing multiple altsetttings for channel/samplesize combinations
by Pavel Hofman 02 May '24

02 May '24

Hi, I am considering implementation of multiple altsettings to f_uac2, so that multiple combinations of channels and samplesizes can be offered to the host. Configuration: -------------- * each altsetting for each direction should define * channel mask * samplesize * hs_bint bInterval * c_sync type (for capture only) Perhaps the easiest config would be allowing lists for the existing parameters (like the multiple samplerates were implemented). All the list params would have to have the same number of items - initial check. First values in the list would apply to altsetting 1, second to altsetting 2 etc. Or the altsetting could be some structured configfs param - please is there any recommended standard for structured configfs params? Should the config also adjust the list of allowed samplerates for each altsetting? Technically it makes sense as higher number of channels can decrease the max samplerate, e.g. for via a TDM interface. If so, it would need either the structured configuration or some "list of lists" format. Implementation: --------------- Parameters could be turned to arrays of fixed predefined sizes, like the p/s_srates. E.g. 5 max. altsettings in each direction would consume only 4 * (5-1) + 3* (5-1) = 28 extra ints (excluding the samplerates config). Currently all descriptor structs are statically pre-allocated as there are only two hard-coded altsettings. IMO the descriptors specific for each altsetting could be allocated dynamically in a loop over all none-zero alsettings. Please may I ask UAC2 gadget "stakeholders" for comments, suggestions, recommendations, so that my eventual initial version was in some generally acceptable direction? Thanks a lot, Pavel.

ASRock N100DC-ITX snd_usb_audio problems
by Florian Paul Schmidt 02 May '24

02 May '24

Hi! I recently acquired a ASRock N100DC-ITX mainboard with the goal to run some audio processing on it. After some tuning I got the board to behave nicely with e.g. cyclictest giving worst case latencies around 10 us with a recent -rt kernel. So the system shoudl be well equipped to run small period sizes. I have two USB audio class 2.0 audio interfaces here. 1. Focusrite 2i2 2nd gen 2. Tascam iXR Both these interfaces work fine on other systems, so I guess they are not the problem. And I used at least the Tascam with period sizes of e.g. 64 and 32 frames and 2 periods without problems (the 0.125 ms microframe resolution is good enough when it comes to the resulting jitter). But on this new system I cannot get either of the two interfaces to run with even 64 frames, 2 periods reliably. I tried jackd1, jack2, and the alsa_loopback program from Fons' libzita-alsa-pcmi. The system is well tuned with xhci IRQs at prio 90, jackd/alsa_loopback at prio 80 and all other kernel irq threads at prio 50. For 64 frames 2 periods 48000 samplerate $ LD_LIBRARY_PATH=../source/ ./alsa_loopback hw:USB hw:USB 48000 64 2 I get: May 02 12:37:35 ogfx100 kernel: retire_capture_urb: 1090 callbacks suppressed in the kernel log (every 5 seconds with the number of callbacks in the same ballpark) and alsa_loopback complaining: Error: pcm_wait returned 0. For 48 frames 2 periods 48000 samplerate (which should actually work better since the period boundaries should fall onto usb frame boundaries.) LD_LIBRARY_PATH=../source/ ./alsa_loopback hw:USB hw:USB 48000 48 2 I get: May 02 12:39:58 ogfx100 kernel: xhci_hcd 0000:00:14.0: WARN Event TRB for slot 4 ep 1 with no TDs queued? over and over in the kernel log and alsa_loopback again complaining as above. On the other hand 48 frames, 3 periods works great! I measure jitter with jack_wakeup in an otherwise empty jack-graph: [fps@ogfx100:~]$ ./src/jack_wakeup/jack_wakeup min: 0.92522 ms; mean: 0.999884ms; max: 1.07727 ms 64 frames, 3 periods works ok-ish: [fps@ogfx100:~]$ ./src/jack_wakeup/jack_wakeup min: 0.938189 ms; mean: 1.33265ms; max: 1.59372 ms with 3 to 4 times the jitter I would expect giving the 0.125 ms microframe length of USB 2. Here I would expect output more like min: 1.25... ms; mean: 1.33265ms; max: 1.5... ms or min: 1.25... ms; mean: 1.33265ms; max: 1.375... ms I suspect that this is not a problem of the snd_usb_audio driver from ALSA but rather a problem with the XHCI in this board, since the combination of cards and snd_usb_audio driver work well on other systems. But maybe you have some insight or suggestions for me to try before reporting to LKML.. Looking forward to your replies and kind regards, FPS P.S.: [fps@ogfx100:~]$ uname -a Linux ogfx100 6.6.25-rt29 #1-NixOS SMP PREEMPT_RT Thu Apr 4 18:23:07 UTC 2024 x86_64 GNU/Linux I have tried with many other kernels though -rt and non-rt.

[PATCH] ALSA: hda: cs35l56: Perform firmware download in the background
by Simon Trimmer 02 May '24

02 May '24

It is possible that during system boot when there multiple devices attempting simultaneous initialization on a slow control bus the download of firmware and tuning data may take a user perceivable amount of time. Adopt a pattern used in the ASoC driver and perform this activity in a background thread so that interactive performance is not impaired.

[PATCH v5 00/18] ASoC: Cleanup MediaTek soundcard machine drivers
by AngeloGioacchino Del Regno 02 May '24

02 May '24

Changes in v5: - Cleaned up MT8186 soundcard migration commit which erroneously had leftovers from development - Changed the mtk_pcm_constraints_data structure to hold pointers to snd_pcm_hw_constraint_list, as to really reuse the const data - Tested again on all of the listed MTK platforms. Changes in v4: - Rebased over next-20240409 - Dropped the first 4 patches from v3 as were already picked by Mark - Fixed W=1 build issue Changes in v3: - Added audio-routing names in enum in all yaml files - Added mention of disallowing old and new properties together in commit message of bindings patches - Fixed validation errors with sound-card-common.yaml inclusion due to missing model property in examples - Removed `else` enforcing headset-codec/speaker-codecs requirement if xxx-dai-link not present to avoid future commit noise as the deprecated statement will disallow deprecated properties as required Changes in v2: - Bindings: Changed link-name/codec/clk-provider to remove `items` and leave just the enum - Moved .*-dai-link pattern additionalProperties after `type: object` - Added ref to sound-card-common.yaml - Fixed dai-link-xxx -> xxx-dai-link typo in example comment This series performs a cleanup of most of the MediaTek AFE drivers and soundcard machine drivers, reducing code duplication and setting a base to be consistent with their devicetree bindings, as many of those are using different properties and nodes for no good reason. Summarizing: - Commonizes functions and ops where possible - Adds a common probe mechanism, increasing maintainability of soundcard drivers for older MediaTek SoCs - Migrates all drivers to support the new bindings - Obviously retains compatibility with old device trees - Reduces machine-specific parameters hardcoding in drivers - Can now set machine-specific params in device tree - Uses the `audio-routing` and `dai-link` nodes like some other non-MediaTek SoC sound drivers - Imposes consistency between MediaTek ASoC machine soundcard drivers bindings - Reduces code size and greatly reduces the amount of code that will be required for newer drivers (retaining compatibility with the old bindings was costly in terms of code size, otherwise this series would've removed ~1000 more lines, or something along that line). This series was (manually) tested on MT8173, MT8192, MT8195 and MT8186 Chromebooks.
