ALSA: bebob: detect the number of available MIDI ports

2021-03-22T11:22:27+00:00

Current implementation counts the number of input/output plugs for MIDI type and uses the count as the number of physical MIDI ports. However, the number of channels of the port represents the count. This commit fixes the bug by additional vendor-specific AVC command extension.

ALSA: firewire-lib/bebob/oxfw: improve response evaluation for AV/C commands

2017-04-05T19:37:23+00:00

In ALSA firewire stack, some AV/C commands are supported, including vendor's extensions. Drivers includes response parser of each command, according to its requirements, while the parser is written with loose fashion in two points; error check and length check. This doesn't cause any issues such as kernel corruption, but should be improved. This commit modifies evaluations of return value on each parsers.

ALSA: bebob: Prepare for device specific operations

2014-05-26T12:31:15+00:00

This commit is for some devices which have its own operations or quirks. Many functionality should be implemented in user land. Then this commit adds functionality related to stream such as sampling frequency or clock source. For help to debug, this commit adds the functionality to get metering information if it's available. To help these functionalities, this commit adds some AV/C commands defined in 'AV/C Audio Subunit Specification (1394TA). Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: bebob: Add commands and connections/streams management

2014-05-26T12:29:29+00:00

This commit adds management functionality for connections and streams. BeBoB uses CMP to manage connections and uses AMDTP for streams. This commit also adds some BridgeCo's AV/C extension commands. There are some BridgeCo's AV/C extension commands but this commit just uses below commands to get device's capability and status: 1.Extended Plug Info commands - Plug Channel Position Specific Data - Plug Type Specific Data - Cluster(Section) Info Specific Data - Plug Input Specific Data 2.Extended Stream Format Information commands - Extended Stream Format Information Command - List Request For Extended Plug Info commands for Cluster Info Specific Data, I pick up 'section' instead of 'cluster' from document to prevent from misunderstanding because 'cluster' is also used in IEC 61883-6.
