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/Kconfig

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/Kconfig

[media] Revert "[media] sound/usb: Use Media Controller API to share media resources"Unfortunately, this patch caused several regressions at au0828 andsnd-usb-audio, like this one: https://bugzilla.kernel.org/show_bug.cgi?id=115561It also showed several troubles at the MC core that handles prettypoorly the memory protections and data lifetime management.So, better to revert it and fix the core before reapplying thischange.This reverts commit aebb2b89bff0 ("[media] sound/usb: Use MediaController API to share media resources")'Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/sound/usb/Kconfig
