[PATCH v8 00/34] Introduce QC USB SND audio offloading support
by Wesley Cheng 12 Oct '23

12 Oct '23

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 Changelog -------------------------------------------- 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.

[PATCH v2 00/16] Harden SSP boards and add TDM support
by Amadeusz Sławiński 12 Oct '23

12 Oct '23

In quite a few places in code there are checks for number of SSPs present on system, to reduce maintenance burden introduce helper functions allowing to get SSP and TDM from machine board configuration. Current mechanism replaces "%d" present in some routes and widget names with SSP number. However there are also configurations which make use of of TDM number, in which case expected behavior would be to have string in form of SSP:TDM - see implementation of avs_i2s_platform_register() in sound/soc/intel/avs/pcm.c. Implement custom function, which parses string and make use of it when parsing topology. While at it make sure that we generate dynamic names only if there is no multiple SSPs or TDMs defined. Migrate all boards to handle TDM if requested. v2: - Fix header functions to be static Amadeusz Sławiński (16): ASoC: Intel: avs: Only create SSP%d snd_soc_dai_driver when requested ASoC: Intel: avs: Introduce helper functions for SSP and TDM handling ASoC: Intel: avs: Improve topology parsing of dynamic strings ASoC: Intel: avs: i2s_test: Validate machine board configuration ASoC: Intel: avs: rt274: Validate machine board configuration ASoC: Intel: avs: rt5682: Validate machine board configuration ASoC: Intel: avs: max98357a: Validate machine board configuration ASoC: Intel: avs: rt298: Validate machine board configuration ASoC: Intel: avs: da7219: Validate machine board configuration ASoC: Intel: avs: es8336: Validate machine board configuration ASoC: Intel: avs: max98373: Validate machine board configuration ASoC: Intel: avs: max98927: Validate machine board configuration ASoC: Intel: avs: nau8825: Validate machine board configuration ASoC: Intel: avs: rt286: Validate machine board configuration ASoC: Intel: avs: rt5663: Validate machine board configuration ASoC: Intel: avs: ssm4567: Validate machine board configuration sound/soc/intel/avs/board_selection.c | 2 +- sound/soc/intel/avs/boards/da7219.c | 17 +++-- sound/soc/intel/avs/boards/es8336.c | 18 +++-- sound/soc/intel/avs/boards/i2s_test.c | 55 ++++++++----- sound/soc/intel/avs/boards/max98357a.c | 18 +++-- sound/soc/intel/avs/boards/max98373.c | 18 +++-- sound/soc/intel/avs/boards/max98927.c | 18 +++-- sound/soc/intel/avs/boards/nau8825.c | 18 +++-- sound/soc/intel/avs/boards/rt274.c | 18 +++-- sound/soc/intel/avs/boards/rt286.c | 19 +++-- sound/soc/intel/avs/boards/rt298.c | 18 +++-- sound/soc/intel/avs/boards/rt5663.c | 18 +++-- sound/soc/intel/avs/boards/rt5682.c | 18 +++-- sound/soc/intel/avs/boards/ssm4567.c | 18 +++-- sound/soc/intel/avs/pcm.c | 28 ++++--- sound/soc/intel/avs/topology.c | 102 +++++++++++++++++++------ sound/soc/intel/avs/utils.h | 65 ++++++++++++++++ 17 files changed, 346 insertions(+), 122 deletions(-) create mode 100644 sound/soc/intel/avs/utils.h base-commit: 7cd4a5a1531109287d8d9d34144020189201c031 -- 2.34.1

[PATCH 00/16] Harden SSP boards and add TDM support
by Amadeusz Sławiński 12 Oct '23

12 Oct '23

In quite a few places in code there are checks for number of SSPs present on system, to reduce maintenance burden introduce helper functions allowing to get SSP and TDM from machine board configuration. Current mechanism replaces "%d" present in some routes and widget names with SSP number. However there are also configurations which make use of of TDM number, in which case expected behavior would be to have string in form of SSP:TDM - see implementation of avs_i2s_platform_register() in sound/soc/intel/avs/pcm.c. Implement custom function, which parses string and make use of it when parsing topology. While at it make sure that we generate dynamic names only if there is no multiple SSPs or TDMs defined. Migrate all boards to handle TDM if requested.

[PATCH] ASoC: cs42l42: Fix missing include of gpio/consumer.h
by Richard Fitzgerald 11 Oct '23

From: Simon Trimmer <simont(a)opensource.cirrus.com> This can now be re-enabled as the sequence to reliably wake the device has been implemented in the shared ASoC code. This has a functional dependency on commit 3df761bdbc8b ("ASoC: cs35l56: Wake transactions need to be issued twice") To protect against this, enabling hibernation is conditional on CS35L56_WAKE_HOLD_TIME_US being defined, which indicates that the new hibernation sequences are available.

[PATCH 0/4] ASoC: makes CPU/Codec channel connection map more generic
by Kuninori Morimoto 11 Oct '23

11 Oct '23

Hi Mark Cc Bard, Pierre-Louis Current ASoC is supporting CPU/Codec = N:M (N < M) connection by using ch_map idea. This patch expand that all connection uses this idea, and no limit of N < M [1]. This patch is tested on Audio-Graph-Card2 with sample dtsi, but needs Tested-by, at least from Intel.

Hi Mark Cc Bard, Pierre-Louis This is v2 patch-set. Current ASoC is supporting CPU/Codec = N:M (N < M) connection by using ch_map idea. This patch-set expands it that all connection uses this idea, and no longer N < M limit [1].
