[PATCH v22 00/38] Introduce QC USB SND audio offloading support
by Wesley Cheng 11 Jun '24

11 Jun '24

Requesting to see if we can get some Acked-By tags, and merge on usb-next. 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 v22: - Removed components tag for the ASoC platform card, as the USB SND kcontrol for notifying userspace of offload capable card achieves similar results. - Due to the above, had to remove the review-by tag for the RST documentation, as changes were made to remove the components tag section. - Took in feedback to make the SOC USB add/remove ports void. - Fixed an issue w/ the USB SND kcontrol management for devices that have multi UAC interfaces. (would attempt to create the kcontrol more than once) - Modified SOC USB card and PCM index select to be based off the num_supported streams that is specified by the USB BE DAI. - Modified comments on selecting the latest USB headset for offloading. Changes in v21: - Added an offload jack disable path from the ASoC platform driver and SOC USB. - Refactored some of the existing SOC USB context look up APIs and created some new helpers to search for the USB context. - Renamed snd_soc_usb_find_format to snd_soc_usb_find_supported_format - Removed some XHCI sideband calls that would allow clients to actually enable the IRQ line associated w/ the secondary interrupter. This is removed because there are other dependencies that are required for that to happen, which are not covered as part of this series, and to avoid confusion. - Due to the above, removed the need to export IMOD setting, and enable/disable interrupter APIs. 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.

[PATCH v1 1/1] treewide: Align match_string() with sysfs_match_string()
by Andy Shevchenko 10 Jun '24

10 Jun '24

Make two APIs look similar. Hence convert match_string() to be a 2-argument macro. In order to avoid unneeded churn, convert all users as well. There is no functional change intended. Signed-off-by: Andy Shevchenko <andriy.shevchenko(a)linux.intel.com> --- Compile tested with `make allyesconfig` and `make allmodconfig` on x86_64, arm, aarch64, powerpc64 (8 builds total). I guess the best is to apply it to Linus' tree directly. And now it seems a good timing as there are no new users of this API either in v6.10-rcX, or in Linux Next. But if you think differently, tell me. arch/powerpc/xmon/xmon.c | 5 ++-- arch/x86/kernel/cpu/mtrr/if.c | 4 +-- crypto/asymmetric_keys/pkcs7_verify.c | 4 +-- drivers/acpi/scan.c | 4 +-- drivers/ata/pata_hpt366.c | 2 +- drivers/ata/pata_hpt37x.c | 2 +- drivers/base/property.c | 6 ++-- drivers/char/ipmi/ipmi_msghandler.c | 2 +- drivers/char/ipmi/ipmi_si_hardcode.c | 2 +- drivers/clk/bcm/clk-bcm2835.c | 4 +-- drivers/clk/rockchip/clk.c | 4 +-- drivers/clk/tegra/clk-tegra124-emc.c | 7 ++--- drivers/cpufreq/amd-pstate.c | 4 +-- drivers/cpufreq/intel_pstate.c | 2 +- .../intel/qat/qat_common/adf_cfg_services.c | 5 ++-- .../gpu/drm/drm_panel_orientation_quirks.c | 2 +- drivers/gpu/drm/i915/display/intel_pipe_crc.c | 2 +- drivers/gpu/drm/nouveau/dispnv04/tvnv17.c | 4 +-- drivers/gpu/drm/nouveau/dispnv50/crc.c | 2 +- drivers/hwmon/ltc4282.c | 14 ++++----- drivers/hwmon/nct6775-platform.c | 6 ++-- drivers/hwtracing/intel_th/msu.c | 2 +- drivers/i2c/busses/i2c-i801.c | 4 +-- drivers/leds/leds-sun50i-a100.c | 2 +- drivers/mfd/omap-usb-host.c | 2 +- drivers/mmc/host/sdhci-xenon-phy.c | 13 ++++----- drivers/mtd/nand/raw/nand_macronix.c | 10 ++----- .../net/ethernet/chelsio/cxgb4/cudbg_lib.c | 6 ++-- .../net/wireless/intel/iwlwifi/mvm/debugfs.c | 2 +- drivers/pci/pcie/aer.c | 2 +- drivers/phy/mediatek/phy-mtk-tphy.c | 8 ++--- drivers/phy/tegra/xusb.c | 4 +-- drivers/pinctrl/mvebu/pinctrl-armada-37xx.c | 6 ++-- drivers/pinctrl/pinmux.c | 6 ++-- drivers/platform/x86/hp/hp-wmi.c | 29 +++++++------------ drivers/platform/x86/msi-ec.c | 4 +-- drivers/power/supply/ab8500_btemp.c | 2 +- drivers/power/supply/ab8500_chargalg.c | 2 +- drivers/power/supply/ab8500_charger.c | 2 +- drivers/power/supply/ab8500_fg.c | 2 +- drivers/staging/gdm724x/gdm_tty.c | 5 ++-- .../int340x_thermal/processor_thermal_rfim.c | 4 +-- .../processor_thermal_wt_req.c | 2 +- drivers/usb/common/common.c | 8 ++--- drivers/usb/dwc3/dwc3-rtk.c | 2 +- drivers/usb/typec/class.c | 14 ++++----- drivers/usb/typec/tipd/core.c | 3 +- drivers/video/fbdev/pxafb.c | 4 +-- fs/bcachefs/compress.c | 2 +- fs/bcachefs/opts.c | 4 +-- fs/bcachefs/util.c | 4 +-- fs/ubifs/auth.c | 8 ++--- include/linux/string.h | 12 +++++++- kernel/cgroup/rdma.c | 2 +- kernel/sched/debug.c | 2 +- kernel/trace/trace.c | 4 +-- kernel/trace/trace_osnoise.c | 4 +-- lib/dynamic_debug.c | 5 ++-- lib/string_helpers.c | 6 ++-- mm/mempolicy.c | 4 +-- mm/vmpressure.c | 4 +-- security/apparmor/lsm.c | 9 +++--- security/integrity/ima/ima_main.c | 2 +- security/integrity/ima/ima_policy.c | 2 +- sound/firewire/oxfw/oxfw.c | 2 +- sound/pci/oxygen/oxygen_mixer.c | 2 +- sound/soc/codecs/max98088.c | 2 +- sound/soc/codecs/max98095.c | 2 +- sound/soc/soc-dapm.c | 5 ++-- 69 files changed, 150 insertions(+), 174 deletions(-) diff --git a/arch/powerpc/xmon/xmon.c b/arch/powerpc/xmon/xmon.c index bd4813bad317..f479cc62674a 100644 --- a/arch/powerpc/xmon/xmon.c +++ b/arch/powerpc/xmon/xmon.c @@ -3478,8 +3478,7 @@ skipbl(void) return c;

alsa-project/alsa-ucm-conf issue #424 was edited from DeepHarsora-Dell: Installed Fedora Rawhide on Dell Latitude 7350 Detachable resulting in no-audio output from onboard speaker and in-built mic (DMIC) can't be detected. (SKU - 0x0C64) Updated the SUT with the following 1. Topology built rightly. 2. Noticed proper SOF Machine driver in upstream as on v.6.10-rc1, able to load the topology. 3. Updated the UCM2 config files as per [[ALSA_UCM_README]](https://github.com/alsa-project/alsa-ucm-conf/blob/master… Below is the error found while alsaucm reload [linuxengg@fedora ~]$ sudo alsaucm reload ALSA lib ucm_subs.c:807:(uc_mgr_get_substituted_value) variable '${var:__RegEx}' is not defined in this context!

[modern hardware] interleaved or plannar?
by GitHub issues - opened 08 Jun '24

08 Jun '24

alsa-project/alsa-lib issue #400 was opened from sylware: To have the less "technical distance" with modern audio hardware (for instance usb audio 2), is it better to have interleaved audio frames each with a pitch, or brutally planar with a pitch per plane?
