From e375b8a045873cf5fb8bf61bf9a0ddfcd484243a Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 12 Jun 2023 10:10:45 +0200 Subject: ALSA: ump: Add more attributes to UMP EP and FB info Add a few more fields to snd_ump_endpoint_info and snd_ump_block_info that are added in the new v1.1 spec. Those are filled by the UMP Stream messages. The rawmidi protocol version is bumped to 2.0.4 to indicate those updates. Also, update the proc outputs to show the newly introduced fields.

Also, the former reserved bit 0 for the client group filter is now used for groupless events. When the bit 0 is set, the groupless events are filtered out and skipped.

Add a new flag bit to snd_ump_endpoint_info to reflect that attribute, too. The flag is set when a USB MIDI device is still in the old MIDI 2.0 without UMP 1.1 support. Then the driver falls back to GTBs, and they are supposed to be static-only.
