* ALSA: usb-audio: USB MIDI 2.0 UMP supportTakashi Iwai2023-05-231-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch provides a basic support for USB MIDI 2.0. As of this patch, the driver creates a UMP device per MIDI I/O endpoints, which serves as a dumb terminal to read/write UMP streams. A new Kconfig CONFIG_SND_USB_AUDIO_MIDI_V2 manages whether to enable or disable the MIDI 2.0 support. Also, the driver provides a new module option, midi2_enable, to allow disabling the MIDI 2.0 at runtime, too. When MIDI 2.0 support is disabled, the driver tries to fall back to the already existing MIDI 1.0 device (each MIDI 2.0 device is supposed to provide the MIDI 1.0 interface at the altset 0). For now, the driver doesn't manage any MIDI-CI or other protocol setups by itself, but relies on the default protocol given via the group terminal block descriptors. The MIDI 1.0 messages on MIDI 2.0 device will be automatically converted in ALSA sequencer in a later patch. As of this commit, the driver 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 UMP So the driver may support multiple UMP Endpoints in theory, although most devices are supposed to have a single UMP EP that can contain up to 16 groups -- which should be large enough.

* media: sound/usb: Use Media Controller API to share media resourcesShuah Khan2019-04-221-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Media Device Allocator API to allows multiple drivers share a media device. This API solves a very common use-case for media devices where one physical device (an USB stick) provides both audio and video. When such media device exposes a standard USB Audio class, a proprietary Video class, two or more independent 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 struct device as the key. Once the media device is allocated by a driver, other drivers can get a reference to it. The media device is released when all the references are released. Change the ALSA driver to use the Media Controller API to share media resources with DVB, and V4L2 drivers on a AU0828 media device. The Media Controller specific initialization is done after sound card is registered. ALSA creates Media interface and entity function graph nodes for Control, Mixer, PCM Playback, and PCM Capture devices. snd_usb_hw_params() will call Media Controller enable source handler interface to request the media resource. If resource request is granted, it will release it from snd_usb_hw_free(). If resource is busy, -EBUSY is returned. Media specific cleanup is done in usb_audio_disconnect().

So, better to revert it and fix the core before reapplying this change.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
