ALSA: seq: Bind UMP device

2023-05-23T10:11:33+00:00

This patch introduces a new ALSA sequencer client for the kernel UMP object, snd-seq-ump-client. It's a UMP version of snd-seq-midi driver, while this driver creates a sequencer client per UMP endpoint which contains (fixed) 16 ports. The UMP rawmidi device is opened in APPEND mode for output, so that multiple sequencer clients can share the same UMP endpoint, as well as the legacy UMP rawmidi devices that are opened in APPEND mode, too. For input, on the other hand, the incoming data is processed on the fly in the dedicated hook, hence it doesn't open a rawmidi device. The UMP packet group is updated upon delivery depending on the target sequencer port (which corresponds to the actual UMP group). Each sequencer port sets a new port type bit, SNDRV_SEQ_PORT_TYPE_MIDI_UMP, in addition to the other standard types for MIDI.

ALSA: seq: Define driver object in each driver

2015-02-12T13:15:54+00:00

This patch moves the driver object initialization and allocation to each driver's module init/exit code like other normal drivers. The snd_seq_driver struct is now published in seq_device.h, and each driver is responsible to define it with proper driver attributes (name, probe and remove) with snd_seq_driver specific attributes as id and argsize fields. The helper functions snd_seq_driver_register(), snd_seq_driver_unregister() and module_snd_seq_driver() are used for simplifying codes. Signed-off-by: Takashi Iwai

ALSA: seq: Clean up device and driver structs

2015-02-12T13:13:47+00:00

Use const string pointer instead of copying the id string to each object. Also drop the status and list fields of snd_seq_device struct that are no longer used. Signed-off-by: Takashi Iwai

ALSA: seq: Rewrite sequencer device binding with standard bus

2015-02-12T10:35:11+00:00

We've used the old house-made code for binding the sequencer device and driver. This can be far better implemented with the standard bus nowadays. This patch refactors the whole sequencer binding code with the bus /sys/bus/snd_seq. The devices appear as id-card-device on this bus and are bound with the drivers corresponding to the given id like the former implementation. The module autoload is also kept like before. There is no change in API functions by this patch, and almost all transitions are kept inside seq_device.c. The proc file output will change slightly but kept compatible as much as possible. Further integration works will follow in later patches. Signed-off-by: Takashi Iwai

Linux-2.6.12-rc2

2005-04-16T22:20:36+00:00

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!
