The Virtual PCM Test Driver
===========================
The Virtual PCM Test Driver emulates a generic PCM device, and can be used for
testing/fuzzing of the userspace ALSA applications, as well as for testing/fuzzing of
the PCM middle layer. Additionally, it can be used for simulating hard to reproduce
problems with PCM devices.
What can this driver do?
~~~~~~~~~~~~~~~~~~~~~~~~
At this moment the driver can do the following things:
* Simulate both capture and playback processes
* Generate random or pattern-based capturing data
* Inject delays into the playback and capturing processes
* Inject errors during the PCM callbacks
It supports up to 8 substreams and 4 channels. Also it supports both interleaved and
non-interleaved access modes.
Also, this driver can check the playback stream for containing the predefined pattern,
which is used in the corresponding selftest (alsa/pcmtest-test.sh) to check the PCM middle
layer data transferring functionality. Additionally, this driver redefines the default
RESET ioctl, and the selftest covers this PCM API functionality as well.
Configuration
-------------
The driver has several parameters besides the common ALSA module parameters:
* fill_mode (bool) - Buffer fill mode (see below)
* inject_delay (int)
* inject_hwpars_err (bool)
* inject_prepare_err (bool)
* inject_trigger_err (bool)
Capture Data Generation
-----------------------
The driver has two modes of data generation: the first (0 in the fill_mode parameter)
means random data generation, the second (1 in the fill_mode) - pattern-based
data generation. Let's look at the second mode.
First of all, you may want to specify the pattern for data generation. You can do it
by writing the pattern to the debugfs file. There are pattern buffer debugfs entries
for each channel, as well as entries which contain the pattern buffer length.
* /sys/kernel/debug/pcmtest/fill_pattern[0-3]
* /sys/kernel/debug/pcmtest/fill_pattern[0-3]_len
To set the pattern for the channel 0 you can execute the following command:
.. code-block:: bash
echo -n mycoolpattern > /sys/kernel/debug/pcmtest/fill_pattern0
Then, after every capture action performed on the 'pcmtest' device the buffer for the
channel 0 will contain 'mycoolpatternmycoolpatternmycoolpatternmy...'.
The pattern itself can be up to 4096 bytes long.
Delay injection
---------------
The driver has 'inject_delay' parameter, which has very self-descriptive name and
can be used for time delay/speedup simulations. The parameter has integer type, and
it means the delay added between module's internal timer ticks.
If the 'inject_delay' value is positive, the buffer will be filled slower, if it is
negative - faster. You can try it yourself by starting a recording in any
audiorecording application (like Audacity) and selecting the 'pcmtest' device as a
source.
This parameter can be also used for generating a huge amount of sound data in a very
short period of time (with the negative 'inject_delay' value).
Errors injection
----------------
This module can be used for injecting errors into the PCM communication process. This
action can help you to figure out how the userspace ALSA program behaves under unusual
circumstances.
For example, you can make all 'hw_params' PCM callback calls return EBUSY error by
writing '1' to the 'inject_hwpars_err' module parameter:
.. code-block:: bash
echo 1 > /sys/module/snd_pcmtest/parameters/inject_hwpars_err
Errors can be injected into the following PCM callbacks:
* hw_params (EBUSY)
* prepare (EINVAL)
* trigger (EINVAL)
Playback test
-------------
This driver can be also used for the playback functionality testing - every time you
write the playback data to the 'pcmtest' PCM device and close it, the driver checks the
buffer for containing the looped pattern (which is specified in the fill_pattern
debugfs file for each channel). If the playback buffer content represents the looped
pattern, 'pc_test' debugfs entry is set into '1'. Otherwise, the driver sets it to '0'.
ioctl redefinition test
-----------------------
The driver redefines the 'reset' ioctl, which is default for all PCM devices. To test
this functionality, we can trigger the reset ioctl and check the 'ioctl_test' debugfs
entry:
.. code-block:: bash
cat /sys/kernel/debug/pcmtest/ioctl_test
If the ioctl is triggered successfully, this file will contain '1', and '0' otherwise.

=================
MIDI 2.0 on Linux
=================
General
=======
MIDI 2.0 is an extended protocol for providing higher resolutions and
more fine controls over the legacy MIDI 1.0. The fundamental changes
introduced for supporting MIDI 2.0 are:
- Support of Universal MIDI Packet (UMP)
- Support of MIDI 2.0 protocol messages
- Transparent conversions between UMP and legacy MIDI 1.0 byte stream
- MIDI-CI for property and profile configurations
UMP is a new container format to hold all MIDI protocol 1.0 and MIDI
2.0 protocol messages. Unlike the former byte stream, it's 32bit
aligned, and each message can be put in a single packet. UMP can send
the events up to 16 "UMP Groups", where each UMP Group contain up to
16 MIDI channels.
MIDI 2.0 protocol is an extended protocol to achieve the higher
resolution and more controls over the old MIDI 1.0 protocol.
MIDI-CI is a high-level protocol that can talk with the MIDI device
for the flexible profiles and configurations. It's represented in the
form of special SysEx.
For Linux implementations, the kernel supports the UMP transport and
the encoding/decoding of MIDI protocols on UMP, while MIDI-CI is
supported in user-space over the standard SysEx.
As of this writing, only USB MIDI device supports the UMP and Linux
2.0 natively. The UMP support itself is pretty generic, hence it
could be used by other transport layers, although it could be
implemented differently (e.g. as a ALSA sequencer client), too.
The access to UMP devices are provided in two ways: the access via
rawmidi device and the access via ALSA sequencer API.
ALSA sequencer API was extended to allow the payload of UMP packets.
It's allowed to connect freely between MIDI 1.0 and MIDI 2.0 sequencer
clients, and the events are converted transparently.
Kernel Configuration
====================
The following new configs are added for supporting MIDI 2.0:
`CONFIG_SND_UMP`, `CONFIG_SND_UMP_LEGACY_RAWMIDI`,
`CONFIG_SND_SEQ_UMP`, `CONFIG_SND_SEQ_UMP_CLIENT`, and
`CONFIG_SND_USB_AUDIO_MIDI_V2`. The first visible one is
`CONFIG_SND_USB_AUDIO_MIDI_V2`, and when you choose it (to set `=y`),
the core support for UMP (`CONFIG_SND_UMP`) and the sequencer binding
(`CONFIG_SND_SEQ_UMP_CLIENT`) will be automatically selected.
Additionally, `CONFIG_SND_UMP_LEGACY_RAWMIDI=y` will enable the
support for the legacy raw MIDI device for UMP Endpoints.
Rawmidi Device with USB MIDI 2.0
================================
When a device supports MIDI 2.0, the USB-audio driver probes and uses
the MIDI 2.0 interface (that is found always at the altset 1) as
default instead of the MIDI 1.0 interface (at altset 0). You can
switch back to the binding with the old MIDI 1.0 interface by passing
`midi2_enable=0` option to snd-usb-audio driver module, too.
The USB audio driver tries to query the UMP Endpoint and UMP Function
Block information that are provided since UMP v1.1, and builds up the
topology based on those information. When the device is older and
doesn't respond to the new UMP inquiries, the driver falls back and
builds the topology based on Group Terminal Block (GTB) information
from the USB descriptor. Some device might be screwed up by the
unexpected UMP command; in such a case, pass `midi2_probe=0` option to
snd-usb-audio driver for skipping the UMP v1.1 inquiries.
When the MIDI 2.0 device is probed, the kernel creates a rawmidi
device for each UMP Endpoint of the device. Its device name is
`/dev/snd/umpC*D*` and different from the standard rawmidi device name
`/dev/snd/midiC*D*` for MIDI 1.0, in order to avoid confusing the
legacy applications accessing mistakenly to UMP devices.
You can read and write UMP packet data directly from/to this UMP
rawmidi device. For example, reading via `hexdump` like below will
show the incoming UMP packets of the card 0 device 0 in the hex
format::
% hexdump -C /dev/snd/umpC0D0
00000000 01 07 b0 20 00 07 b0 20 64 3c 90 20 64 3c 80 20 |... ... d<. d<. |
Unlike the MIDI 1.0 byte stream, UMP is a 32bit packet, and the size
for reading or writing the device is also aligned to 32bit (which is 4
bytes).
The 32-bit words in the UMP packet payload are always in CPU native
endianness. Transport drivers are responsible to convert UMP words
from / to system endianness to required transport endianness / byte
order.
When `CONFIG_SND_UMP_LEGACY_RAWMIDI` is set, the driver creates
another standard raw MIDI device additionally as `/dev/snd/midiC*D*`.
This contains 16 substreams, and each substream corresponds to a
(0-based) UMP Group. Legacy applications can access to the specified
group via each substream in MIDI 1.0 byte stream format. With the
ALSA rawmidi API, you can open the arbitrary substream, while just
opening `/dev/snd/midiC*D*` will end up with opening the first
substream.
Each UMP Endpoint can provide the additional information, constructed
from the information inquired via UMP 1.1 Stream messages or USB MIDI
2.0 descriptors. And a UMP Endpoint may contain one or more UMP
Blocks, where UMP Block is an abstraction introduced in the ALSA UMP
implementations to represent the associations among UMP Groups. UMP
Block corresponds to Function Block in UMP 1.1 specification. When
UMP 1.1 Function Block information isn't available, it's filled
partially from Group Terminal Block (GTB) as defined in USB MIDI 2.0
specifications.
The information of UMP Endpoints and UMP Blocks are found in the proc
file `/proc/asound/card*/midi*`. For example::
% cat /proc/asound/card1/midi0
ProtoZOA MIDI
Type: UMP
EP Name: ProtoZOA
EP Product ID: ABCD12345678
UMP Version: 0x0000
Protocol Caps: 0x00000100
Protocol: 0x00000100
Num Blocks: 3
Block 0 (ProtoZOA Main)
Direction: bidirection
Active: Yes
Groups: 1-1
Is MIDI1: No
Block 1 (ProtoZOA Ext IN)
Direction: output
Active: Yes
Groups: 2-2
Is MIDI1: Yes (Low Speed)
....
Note that `Groups` field shown in the proc file above indicates the
1-based UMP Group numbers (from-to).
Those additional UMP Endpoint and UMP Block information can be
obtained via the new ioctls `SNDRV_UMP_IOCTL_ENDPOINT_INFO` and
`SNDRV_UMP_IOCTL_BLOCK_INFO`, respectively.
The rawmidi name and the UMP Endpoint name are usually identical, and
in the case of USB MIDI, it's taken from `iInterface` of the
corresponding USB MIDI interface descriptor. If it's not provided,
it's copied from `iProduct` of the USB device descriptor as a
fallback.
The Endpoint Product ID is a string field and supposed to be unique.
It's copied from `iSerialNumber` of the device for USB MIDI.
The protocol capabilities and the actual protocol bits are defined in
`asound.h`.
ALSA Sequencer with USB MIDI 2.0
================================
In addition to the rawmidi interfaces, ALSA sequencer interface
supports the new UMP MIDI 2.0 device, too. Now, each ALSA sequencer
client may set its MIDI version (0, 1 or 2) to declare itself being
either the legacy, UMP MIDI 1.0 or UMP MIDI 2.0 device, respectively.
The first, legacy client is the one that sends/receives the old
sequencer event as was. Meanwhile, UMP MIDI 1.0 and 2.0 clients send
and receive in the extended event record for UMP. The MIDI version is
seen in the new `midi_version` field of `snd_seq_client_info`.
A UMP packet can be sent/received in a sequencer event embedded by
specifying the new event flag bit `SNDRV_SEQ_EVENT_UMP`. When this
flag is set, the event has 16 byte (128 bit) data payload for holding
the UMP packet. Without the `SNDRV_SEQ_EVENT_UMP` bit flag, the event
is treated as a legacy event as it was (with max 12 byte data
payload).
With `SNDRV_SEQ_EVENT_UMP` flag set, the type field of a UMP sequencer
event is ignored (but it should be set to 0 as default).
The type of each client can be seen in `/proc/asound/seq/clients`.
For example::
% cat /proc/asound/seq/clients

Here you can find two types of kernel clients, "Legacy" for client 14,
and "UMP MIDI1" for client 20, which is a USB MIDI 2.0 device.
A USB MIDI 2.0 client gives always the port 0 as "MIDI 2.0" and the
rest ports from 1 for each UMP Group (e.g. port 1 for Group 1).
In this example, the device has three active groups (Main, Ext IN and
Ext OUT), and those are exposed as sequencer ports from 1 to 3.
The "MIDI 2.0" port is for a UMP Endpoint, and its difference from
other UMP Group ports is that UMP Endpoint port sends the events from
the all ports on the device ("catch-all"), while each UMP Group port
sends only the events from the given UMP Group.
Also, UMP groupless messages (such as the UMP message type 0x0f) are
sent only to the UMP Endpoint port.
Note that, although each UMP sequencer client usually creates 16
ports, those ports that don't belong to any UMP Blocks (or belonging
to inactive UMP Blocks) are marked as inactive, and they don't appear
in the proc outputs. In the example above, the sequencer ports from 4
to 16 are present but not shown there.
The proc file above shows the UMP Block information, too. The same
entry (but with more detailed information) is found in the rawmidi
proc output.
When clients are connected between different MIDI versions, the events
are translated automatically depending on the client's version, not
only between the legacy and the UMP MIDI 1.0/2.0 types, but also
between UMP MIDI 1.0 and 2.0 types, too. For example, running
`aseqdump` program on the ProtoZOA Main port in the legacy mode will
give you the output like::
% aseqdump -p 20:1
Waiting for data. Press Ctrl+C to end.
Source Event Ch Data
20:1 Note on 0, note 60, velocity 100
20:1 Note off 0, note 60, velocity 100
20:1 Control change 0, controller 11, value 4
When you run `aseqdump` in MIDI 2.0 mode, it'll receive the high
precision data like::
% aseqdump -u 2 -p 20:1
Waiting for data. Press Ctrl+C to end.
Source Event Ch Data
20:1 Note on 0, note 60, velocity 0xc924, attr type = 0, data = 0x0
20:1 Note off 0, note 60, velocity 0xc924, attr type = 0, data = 0x0
20:1 Control change 0, controller 11, value 0x2000000
while the data is automatically converted by ALSA sequencer core.
Rawmidi API Extensions
======================
* The additional UMP Endpoint information can be obtained via the new
ioctl `SNDRV_UMP_IOCTL_ENDPOINT_INFO`. It contains the associated
card and device numbers, the bit flags, the protocols, the number of
UMP Blocks, the name string of the endpoint, etc.
The protocols are specified in two field, the protocol capabilities
and the current protocol. Both contain the bit flags specifying the
MIDI protocol version (`SNDRV_UMP_EP_INFO_PROTO_MIDI1` or
`SNDRV_UMP_EP_INFO_PROTO_MIDI2`) in the upper byte and the jitter
reduction timestamp (`SNDRV_UMP_EP_INFO_PROTO_JRTS_TX` and
`SNDRV_UMP_EP_INFO_PROTO_JRTS_RX`) in the lower byte.
A UMP Endpoint may contain up to 32 UMP Blocks, and the number of
the currently assigned blocks are shown in the Endpoint information.
* Each UMP Block information can be obtained via another new ioctl
`SNDRV_UMP_IOCTL_BLOCK_INFO`. The block ID number (0-based) has to
be passed for the block to query. The received data contains the
associated the direction of the block, the first associated group ID
(0-based) and the number of groups, the name string of the block,
etc.
The direction is either `SNDRV_UMP_DIR_INPUT`,
`SNDRV_UMP_DIR_OUTPUT` or `SNDRV_UMP_DIR_BIDIRECTION`.
* For the device supports UMP v1.1, the UMP MIDI protocol can be
switched via "Stream Configuration Request" message (UMP type 0x0f,
status 0x05). When UMP core receives such a message, it updates the
UMP EP info and the corresponding sequencer clients as well.
Control API Extensions
======================
* The new ioctl `SNDRV_CTL_IOCTL_UMP_NEXT_DEVICE` is introduced for
querying the next UMP rawmidi device, while the existing ioctl
`SNDRV_CTL_IOCTL_RAWMIDI_NEXT_DEVICE` queries only the legacy
rawmidi devices.
For setting the subdevice (substream number) to be opened, use the
ioctl `SNDRV_CTL_IOCTL_RAWMIDI_PREFER_SUBDEVICE` like the normal
rawmidi.
* Two new ioctls `SNDRV_CTL_IOCTL_UMP_ENDPOINT_INFO` and
`SNDRV_CTL_IOCTL_UMP_BLOCK_INFO` provide the UMP Endpoint and UMP
Block information of the specified UMP device via ALSA control API
without opening the actual (UMP) rawmidi device.
The `card` field is ignored upon inquiry, always tied with the card
of the control interface.
Sequencer API Extensions
========================
* `midi_version` field is added to `snd_seq_client_info` to indicate
the current MIDI version (either 0, 1 or 2) of each client.
When `midi_version` is 1 or 2, the alignment of read from a UMP
sequencer client is also changed from the former 28 bytes to 32
bytes for the extended payload. The alignment size for the write
isn't changed, but each event size may differ depending on the new
bit flag below.
* `SNDRV_SEQ_EVENT_UMP` flag bit is added for each sequencer event
flags. When this bit flag is set, the sequencer event is extended
to have a larger payload of 16 bytes instead of the legacy 12
bytes, and the event contains the UMP packet in the payload.
* The new sequencer port type bit (`SNDRV_SEQ_PORT_TYPE_MIDI_UMP`)
indicates the port being UMP-capable.
* The sequencer ports have new capability bits to indicate the
inactive ports (`SNDRV_SEQ_PORT_CAP_INACTIVE`) and the UMP Endpoint
port (`SNDRV_SEQ_PORT_CAP_UMP_ENDPOINT`).
* The event conversion of ALSA sequencer clients can be suppressed the
new filter bit `SNDRV_SEQ_FILTER_NO_CONVERT` set to the client info.
For example, the kernel pass-through client (`snd-seq-dummy`) sets
this flag internally.
* The port information gained the new field `direction` to indicate
the direction of the port (either `SNDRV_SEQ_PORT_DIR_INPUT`,
`SNDRV_SEQ_PORT_DIR_OUTPUT` or `SNDRV_SEQ_PORT_DIR_BIDIRECTION`).
* Another additional field for the port information is `ump_group`
which specifies the associated UMP Group Number (1-based).
When it's non-zero, the UMP group field in the UMP packet updated
upon delivery to the specified group (corrected to be 0-based).
Each sequencer port is supposed to set this field if it's a port to
specific to a certain UMP group.
* Each client may set the additional event filter for UMP Groups in
`group_filter` bitmap. The filter consists of bitmap from 1-based
Group numbers. For example, when the bit 1 is set, messages from
Group 1 (i.e. the very first group) are filtered and not delivered.
The bit 0 is used for filtering UMP groupless messages.
* Two new ioctls are added for UMP-capable clients:
`SNDRV_SEQ_IOCTL_GET_CLIENT_UMP_INFO` and
`SNDRV_SEQ_IOCTL_SET_CLIENT_UMP_INFO`. They are used to get and set
either `snd_ump_endpoint_info` or `snd_ump_block_info` data
associated with the sequencer client. The USB MIDI driver provides
those information from the underlying UMP rawmidi, while a
user-space client may provide its own data via `*_SET` ioctl.
For an Endpoint data, pass 0 to the `type` field, while for a Block
data, pass the block number + 1 to the `type` field.
Setting the data for a kernel client shall result in an error.
* With UMP 1.1, Function Block information may be changed
dynamically. When the update of Function Block is received from the
device, ALSA sequencer core changes the corresponding sequencer port
name and attributes accordingly, and notifies the changes via the
announcement to the ALSA sequencer system port, similarly like the
normal port change notification.
