46757a3e - ALSA: FCP: Add Focusrite Control Protocol driver

Thu, 16 Jan 2025 17:47:38 +0000

ALSA: FCP: Add Focusrite Control Protocol driverAdd a new kernel driver for the Focusrite Control Protocol (FCP),which is used by Focusrite Scarlett 2nd Gen, 3rd Gen, 4th Gen, ClarettUSB, Clarett+, and Vocaster series audio interfaces. This driverprovides a user-space control interface via ALSA's hwdep subsystem.Unlike the existing Scarlett2 driver which implements all ALSAcontrols in kernel space, this new FCP driver takes a differentapproach by providing a minimal kernel interface that allows auser-space driver to send FCP commands and receive notifications. Theonly control implemented in kernel space is the Level Meter, since itrequires frequent polling of volatile data.While this driver supports all interfaces that the Scarlett2 driverworks with, it is initially enabled only for 4th Gen 16i16, 18i16,and 18i20 interfaces that are not supported by the Scarlett2 driver.Signed-off-by: Geoffrey D.

ff49d1df - ALSA: usb-audio: USB MIDI 2.0 UMP support

Tue, 23 May 2023 07:53:30 +0000

ALSA: usb-audio: USB MIDI 2.0 UMP supportThis patch provides a basic support for USB MIDI 2.0. As of thispatch, the driver creates a UMP device per MIDI I/O endpoints, whichserves as a dumb terminal to read/write UMP streams.A new Kconfig CONFIG_SND_USB_AUDIO_MIDI_V2 manages whether to enableor disable the MIDI 2.0 support. Also, the driver provides a newmodule option, midi2_enable, to allow disabling the MIDI 2.0 atruntime, too. When MIDI 2.0 support is disabled, the driver tries tofall back to the already existing MIDI 1.0 device (each MIDI 2.0device is supposed to provide the MIDI 1.0 interface at the altset0).For now, the driver doesn't manage any MIDI-CI or other protocolsetups by itself, but relies on the default protocol given via thegroup terminal block descriptors.The MIDI 1.0 messages on MIDI 2.0 device will be automaticallyconverted in ALSA sequencer in a later patch. As of this commit, thedriver accepts merely the rawmidi UMP accesses.The driver builds up the topology in the following way:- Create an object for each MIDI endpoint belonging to the USB interface- Find MIDI EP "pairs" that share the same GTB; note that MIDI EP is unidirectional, while UMP is (normally) bidirectional, so two MIDI EPs can form a single UMP EP- A UMP endpoint object is created for each I/O pair- For remaining "solo" MIDI EPs, create unidirectional UMP EPs- Finally, parse GTBs and fill the protocol bits on each UMPSo the driver may support multiple UMP Endpoints in theory, althoughmost devices are supposed to have a single UMP EP that can contain upto 16 groups -- which should be large enough.Reviewed-by: Jaroslav Kysela Link: https://lore.kernel.org/r/20230523075358.9672-10-tiwai@suse.deSigned-off-by: Takashi Iwai List of files: /linux-6.15/sound/usb/Makefile

ALSA: usb-audio: Factor out the implicit feedback quirk codeThe code dealing with the implicit feedback mode grew recently, andit's becoming messy. As we receive more and more devices that needthe similar handling, it's better to be processed through a tableinstead of the open code.This patch moves the code that is relevant with parsing the implicitfeedback mode and some helpers into another file, implicit.c.

66354f18 - media: sound/usb: Use Media Controller API to share media resources

Tue, 02 Apr 2019 00:40:22 +0000

media: sound/usb: Use Media Controller API to share media resourcesMedia Device Allocator API to allows multiple drivers share a media device.This API solves a very common use-case for media devices where one physicaldevice (an USB stick) provides both audio and video. When such media deviceexposes a standard USB Audio class, a proprietary Video class, two or moreindependent drivers will share a single physical USB bridge. In such cases,it is necessary to coordinate access to the shared resource.Using this API, drivers can allocate a media device with the shared structdevice as the key. Once the media device is allocated by a driver, otherdrivers can get a reference to it. The media device is released when allthe references are released.Change the ALSA driver to use the Media Controller API to share mediaresources with DVB, and V4L2 drivers on a AU0828 media device.The Media Controller specific initialization is done after sound card isregistered. ALSA creates Media interface and entity function graph nodesfor Control, Mixer, PCM Playback, and PCM Capture devices.snd_usb_hw_params() will call Media Controller enable source handlerinterface to request the media resource. If resource request is granted,it will release it from snd_usb_hw_free(). If resource is busy, -EBUSY isreturned.Media specific cleanup is done in usb_audio_disconnect().Reviewed-by: Takashi Iwai Signed-off-by: Shuah Khan Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/sound/usb/Makefile

b2441318 - License cleanup: add SPDX GPL-2.0 license identifier to files with no license

Wed, 01 Nov 2017 14:07:57 +0000

License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseMany source files in the tree are missing licensing information, whichmakes it harder for compliance tools to determine the correct license.By default all files without license information are under the defaultlicense of the kernel, which is GPL version 2.Update the files which contain no license information with the 'GPL-2.0'SPDX license identifier. The SPDX identifier is a legally bindingshorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart andPhilippe Ombredanne.How this work was done:Patches were generated and checked against linux-4.14-rc6 for a subset ofthe use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information,Further patches will be generated in subsequent months to fix up caseswhere non-standard license headers were used, and references to licensehad to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied toa file was done in a spreadsheet of side by side results from of theoutput of two independent scanners (ScanCode & Windriver) producing SPDXtag:value files created by Philippe Ombredanne. Philippe prepared thebase worksheet, and did an initial spot review of a few 1000 files.The 4.13 kernel was the starting point of the analysis with 60,537 filesassessed. Kate Stewart did a file by file comparison of the scannerresults in the spreadsheet to determine which SPDX license identifier(s)to be applied to the file. She confirmed any determination that was notimmediately clear with lawyers working with the Linux Foundation.Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines).All documentation files were explicitly excluded.The following heuristics were used to determine which SPDX licenseidentifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time.In total, over 70 hours of logged manual review was done on thespreadsheet to determine the SPDX license identifiers to apply to thesource files by Kate, Philippe, Thomas and, in some cases, confirmationby lawyers working with the Linux Foundation.Kate also obtained a third independent scan of the 4.13 code base fromFOSSology, and compared selected files where the other two scannersdisagreed against that SPDX file, to see if there was new insights. TheWindriver scanner is based on an older version of FOSSology in part, sothey are related.Thomas did random spot checks in about 500 files from the spreadsheetsfor the uapi headers and agreed with SPDX license identifier in thefiles he inspected. For the non-uapi files Thomas did random spot checksin about 15000 files.In initial set of patches against 4.14-rc6, 3 files were found to havecopy/paste license identifier errors, and have been fixed to reflect thecorrect identifier.Additionally Philippe spent 10 hours this week doing a detailed manualinspection and review of the 12,461 patched files from the initial patchversion early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correctThis produced a worksheet with 20 files needing minor correction. Thisworksheet was then exported into 3 different .csv files for thedifferent types of files to be modified.These .csv files were then reviewed by Greg. Thomas wrote a script toparse the csv files and add the proper SPDX tag to the file, in theformat that the file expected. This script was further refined by Gregbased on the output to detect more types of files automatically and todistinguish between header and source .c files (which need differentcomment types.) Finally Greg ran the script using the .csv files togenerate the patches.Reviewed-by: Kate Stewart Reviewed-by: Philippe Ombredanne Reviewed-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/sound/usb/Makefile

ALSA: usb-audio: Scarlett mixer interface for 6i6, 18i6, 18i8 and 18i20This code contains the Scarlett mixer interface code that was originallywritten by Tobias Hoffman and Robin Gareus. Because the device doesn'tproperly implement UAC2 this code adds a mixer quirk for the device.Changes from the original code include removing the metering code along withdead code and comments. Compiler warnings were fixed. The code to initializethe sampling rate was causing a crash this was fixed as discussed on themailing list. Error, and info messages were convered to dev_err and dev_infointerfaces. The custom scarlett_mixer_elem_info struct was replaced with themore generic usb_mixer_elem_info to be able to recycle more code from mixer.c.This patch also makes additional modifications based on upstream comments.Individual control creation functions are removed and a genericfunction is no used. Macros for function calls are removed to improvereadability. Hardcoded control initialization is removed. Save to HWfunctionality has been removed. Strings for enums are created dynamically forthe mixer.
