8b645922 - usb: gadget: Add support for USB MIDI 2.0 function driver

Tue, 25 Jul 2023 06:22:00 +0000

usb: gadget: Add support for USB MIDI 2.0 function driverThis patch adds the support for USB MIDI 2.0 gadget function driver.The driver emulates a USB MIDI 2.0 interface with one or more UMPEndpoints, where each of UMP Endpoint is a pair of MIDI Endpoints forhandling MIDI 2.0 UMP packets. When the function driver is bound, thedriver creates an ALSA card object with UMP rawmidi devices. This isa kind of loop-back where the incoming and upcoming UMP packetsfrom/to the MIDI 2.0 UMP Endpoints are transferred as-is. Inaddition, legacy (MIDI 1.0) rawmidi devices are created, so thatlegacy applications can work in the gadget side, too.When a USB MIDI 2.0 gadget interface appears, the connected host canuse it with the snd-usb-audio driver where MIDI 2.0 support isenabled. Both gadget and connected hosts will have the similar UMPEndpoint and Function Block (or Group Terminal Block) information.Slight differences are the direction and UI-hint bits; it's due to thenature of gadget driver, and the input/output direction is swapped inboth sides (the input for gadget is the output for host, and viceversa).The driver supports the brand-new UMP v1.1 feature, including the UMPStream message handling for providing UMP Endpoint and Function Blockinformation as well as dealing with the MIDI protocol switch. Thedriver responds to UMP Stream messages by itself. OTOH, MIDI-CImessage handling isn't implemented in the kernel driver; it should beprocessed in the user-space through the loopback UMP device.As of this patch, the whole configuration is fixed, providing only onebidirectional UMP Endpoint containing a single FB/GTB with a singleUMP Group. The configuration will be dynamically changeable in thefollowing patches.The traditional MIDI 1.0 is still provided in the altset 0 (which ismandatory per spec). But it's only about the configuration, and noactual I/O will be running for the altset 0 as of this patch. Theproper support MIDI 1.0 altset will follow in later patches, too.Signed-off-by: Takashi Iwai Link: https://lore.kernel.org/r/20230725062206.9674-2-tiwai@suse.deSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/gadget/function/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/drivers/usb/gadget/function/Makefile

0591bc23 - usb: gadget: add f_uac1 variant based on a new u_audio api

Sun, 18 Jun 2017 13:23:54 +0000

usb: gadget: add f_uac1 variant based on a new u_audio apiThis patch adds a new function 'f_uac1'(f_uac1 with virtual "ALSA card") thatuses recently created u_audio API. Comparingto legacy f_uac1 function implementation itdoesn't require any real Audio codec to bepresent on the device. In f_uac1 audiostreams are simply sinked to and sourcedfrom a virtual ALSA sound card createdusing u_audio API.Legacy f_uac1 approach is to write audiosamples directly to existing ALSA soundcardf_uac1 approach is more generic/flexibleone - create an ALSA sound card thatrepresents USB Audio function and allows tobe used by userspace application thatmay choose to do whatever it wants with thedata received from the USB Host and chooseto provide whatever it wants as audio datato the USB Host.f_uac1 also has capture support (gadget->host)thanks to easy implementation via u_audio.By default, capture interface has 48000kHz/2chconfiguration, same as playback channel has.f_uac1 descriptors naming conventionuses f_uac2 driver naming convention thatmakes it more common and meaningful.Comparing to f_uac1_legacy, the f_uac1 doesn'thave volume/mute functionality. This is becausethe f_uac1 volume/mute feature unit was dummyimplementation since that driver creation (2009)and never had any real volume control or mutefunctionality, so there is no any differencehere.Since f_uac1 functionality, exposedinterface to userspace (virtual ALSA card),input parameters are so different comparingto f_uac1_legacy, that there is no anyreason to keep them in the same file/module,and separate function was created.g_audio can be built using one of existingUAC functions (f_uac1, f_uac1_legacy or f_uac2)Signed-off-by: Ruslan Bilovol Signed-off-by: Felipe Balbi List of files: /linux-6.15/drivers/usb/gadget/function/Makefile
