Hi,
this is a (largish) patch set for adding the support of MIDI 2.0
functionality, mainly targeted for USB devices. MIDI 2.0 is a
complete overhaul of the 40-years old MIDI 1.0. Unlike MIDI 1.0 byte
stream, MIDI 2.0 uses packets in 32bit words for Universal MIDI Packet
(UMP) protocol. It supports both MIDI 1.0 commands for compatibility
and the extended MIDI 2.0 commands for higher resolutions and more
functions.
For supporting the UMP, the patch set extends the existing ALSA
rawmidi and sequencer interfaces, and adds the USB MIDI 2.0 support to
the standard USB-audio driver.
The rawmidi for UMP has a different device name (/dev/snd/umpC*D*) and
it reads/writes UMP packet data in 32bit CPU-native endianness. For
the old MIDI 1.0 applications, the legacy rawmidi interface is
provided, too.
As default, USB-audio driver will take the alternate setting for MIDI
2.0 interface, and the compatibility with MIDI 1.0 is provided via the
rawmidi common layer. However, user may let the driver falling back
to the old MIDI 1.0 interface by a module option, too.
A UMP-capable rawmidi device can create the corresponding ALSA
sequencer client(s) to support the UMP Endpoint and UMP Group
connections. As a nature of ALSA sequencer, arbitrary connections
between clients/ports are allowed, and the ALSA sequencer core
performs the automatic conversions for the connections between a new
UMP sequencer client and a legacy MIDI 1.0 sequencer client. It
allows the existing application to use MIDI 2.0 devices without
changes.
The MIDI-CI, which is another major extension in MIDI 2.0, isn't
covered by this patch set. It would be implemented rather in
user-space.
Roughly speaking, the first half of this patch set is for extending
the rawmidi and USB-audio, and the second half is for extending the
ALSA sequencer interface.
The patch set is based on 6.4-rc2 kernel, but all patches can be
cleanly applicable on 6.2 and 6.3 kernels, too (while 6.1 and older
kernels would need minor adjustment for uapi header changes).
The updates for alsa-lib and alsa-utils will follow shortly later.
The author thanks members of MIDI Association OS/API Working Group,
especially Andrew Mee, for great helps for the initial design and
debugging / testing the drivers.

snd_rawmidi_kernel_open() is used only internally from ALSA sequencer,
so far, and parsing the card / device matching table at each open is
redundant, as each sequencer client already gets the rawmidi object
beforehand.
This patch optimizes the path by passing the rawmidi object directly
at snd_rawmidi_kernel_open(). This is also a preparation for the
upcoming UMP rawmidi I/O support.

A new callback, ioctl, is added to snd_rawmidi_global_ops for allowing
the driver to deal with the own ioctls. This is another preparation
patch for the upcoming UMP support.

This patch adds the support helpers for UMP (Universal MIDI Packet) in
ALSA core.
The basic design is that a rawmidi instance is assigned to each UMP
Endpoint. A UMP Endpoint provides a UMP stream, typically
bidirectional (but can be also uni-directional, too), which may hold
up to 16 UMP Groups, where each UMP (input/output) Group corresponds
to the traditional MIDI I/O Endpoint.
Additionally, the ALSA UMP abstraction provides the multiple UMP
Blocks that can be assigned to each UMP Endpoint. A UMP Block is a
metadata to hold the UMP Group clusters, and can represent the
functions assigned to each UMP Group. A typical implementation of UMP
Block is the Group Terminal Blocks of USB MIDI 2.0 specification.
For distinguishing from the legacy byte-stream MIDI device, a new
device "umpC*D*" will be created, instead of the standard (MIDI 1.0)
devices "midiC*D*". The UMP instance can be identified by the new
rawmidi info bit SNDRV_RAWMIDI_INFO_UMP, too.
A UMP rawmidi device reads/writes only in 4-bytes words alignment,
stored in CPU native endianness.
The transmit and receive functions take care of the input/out data
alignment, and may return zero or aligned size, and the params ioctl
may return -EINVAL when the given input/output buffer size isn't
aligned.
A few new UMP-specific ioctls are added for obtaining the new UMP
endpoint and block information.
As of this commit, no ALSA sequencer instance is attached to UMP
devices yet. They will be supported by later patches.
Along with those changes, the protocol version for rawmidi is bumped
to 2.0.3.

Applications may look for rawmidi devices with the ioctl
SNDRV_CTL_IOCTL_RAWMIDI_NEXT_DEVICE. Returning a UMP device from this
ioctl may confuse the existing applications that support only the
legacy rawmidi.
This patch changes the code to skip the UMP devices from the lookup
for avoiding the confusion, and introduces a new ioctl to look for the
UMP devices instead.

UMP devices may have more interesting information than the traditional
rawmidi. Extend the rawmidi_global_ops to allow the optional proc
info output and show some more bits in the proc file for UMP.
Note that the "Groups" field shows the first and the last UMP Groups,
and both numbers are 1-based (i.e. the first group is 1).

We're going to create rawmidi objects for MIDI 2.0 in a different code
from the current code for USB-MIDI 1.0. As a preliminary work, this
patch adds the number of rawmidi objects to keep globally in a
USB-audio card instance, so that it can be referred from both MIDI 1.0
and 2.0 code.

Define new structs and constants from USB MIDI 2.0 specification,
to be used in the upcoming MIDI 2.0 support in USB-audio driver.
A new class-specific endpoint descriptor and group terminal block
descriptors are defined.

To: alsa-devel; +Cc: linux-kernel
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.

USB descriptor may provide a nicer name for USB interface, and we may
take it as the UMP Endpoint name. The UMP EP name is copied as the
rawmidi name, too.
Also, fill the UMP block product_id field from the iSerialNumber
string of the USB device descriptor as a recommended unique id, too.

A single USB audio device may have multiple interfaces for different
purposes (e.g. audio, MIDI and HID), where the iInterface descriptor
of each interface may contain an own suffix, e.g. "MIDI" for a MIDI
interface. as such a suffix is superfluous as a rawmidi and UMP
Endpoint name, this patch trims the superfluous "MIDI" suffix from the
name string.

USB MIDI spec defines the Group Terminal Blocks (GTB) that associate
multiple UMP Groups. Those correspond to snd_ump_block entities in
ALSA UMP abstraction, and now we create those UMP Block objects for
each UMP Endpoint from the parsed GTB information.

This is a code refactoring for abstracting the rawmidi access to the
UMP's own helpers. It's a preliminary work for the later code
refactoring of the UMP layer.
Until now, we access to the rawmidi substream directly from the
driver via rawmidi access helpers, but after this change, the driver
is supposed to access via the newly introduced snd_ump_ops and
receive/transmit via snd_ump_receive() and snd_ump_transmit() helpers.
As of this commit, those are merely wrappers for the rawmidi
substream, and no much function change is seen here.

To: alsa-devel; +Cc: linux-kernel
This patch extends the UMP core code to support the legacy MIDI 1.0
rawmidi devices. When the new kconfig CONFIG_SND_UMP_LEGACY_RAWMIDI
is set, the UMP core allows to attach an additional rawmidi device for
each UMP Endpoint. The rawmidi device contains 16 substreams where
each substream corresponds to a UMP Group belonging to the EP. The
device reads/writes the legacy MIDI 1.0 byte streams and translates
from/to UMP packets.
The legacy rawmidi devices are exclusive with the UMP rawmidi devices,
hence both of them can't be opened at the same time unless the UMP
rawmidi is opened in APPEND mode.

When parsing Group Terminal Blocks, we overwrote the preferred
protocol and the protocol capabilities silently from the last parsed
GTB. This patch adds the information print indicating the unexpected
overrides instead of silent action.

There can be a small memory hole that may not be cleared at expanding
an event with the variable length type. Make sure to clear it.

data starting from the given byte offset. It'll be used by the new
UMP sequencer code later.

Introduce the new helpers, snd_seq_kernel_client_get() and _put() for
kernel client drivers to treat the snd_seq_client more directly.
This allows us to reduce the exported symbols and APIs at each time we
need to access some field in future.

The broadcast and multicast supports have been never enabled.
Let's drop the dead code.

We didn't check if a port with the given port number has been already
present at creating a new port. Check it and return -EBUSY properly
if the port number conflicts.

The client type and the port info validity check should be done before
actually creating a port, instead of unnecessary create-and-scratch.

Some port numbers are special, such as 254 for subscribers and 255 for
broadcast. Return error if application tries to create such a port.

For the future extension of ALSA sequencer ABI, introduce a new ioctl
SNDRV_SEQ_IOCTL_USER_PVERSION. This is similar like the ioctls used
in PCM and other interfaces, for an application to specify its
supporting ABI version.
The use of this ioctl will be mandatory for the upcoming UMP support.

From: Takashi Iwai @ 2023-05-19 9:31 UTC (permalink / raw)
To: alsa-devel; +Cc: linux-kernel
Starting from this commit, we add the basic support of UMP (Universal
MIDI Packet) events on ALSA sequencer infrastructure. The biggest
change here is that, for transferring UMP packets that are up to 128
bits, we extend the data payload of ALSA sequencer event record when
the client is declared to support for the new UMP events.
A new event flag bit, SNDRV_SEQ_EVENT_UMP, is defined and it shall be
set for the UMP packet events that have the larger payload of 128
bits, defined as struct snd_seq_ump_event.
For applications that want to access the UMP packets, first of all, a
sequencer client has to declare the user-protocol to match with the
latest one via the new SNDRV_SEQ_IOCTL_USER_PVERSION; otherwise it's
treated as if a legacy client without UMP support.
Then the client can switch to the new UMP mode (MIDI 1.0 or MIDI 2.0)
with a new field, midi_version, in snd_seq_client_info. When switched
to UMP mode (midi_version = 1 or 2), the client can write the UMP
events with SNDRV_SEQ_EVENT_UMP flag. For reads, the alignment size
is changed from snd_seq_event (28 bytes) to snd_seq_ump_event (32
bytes). When a UMP sequencer event is delivered to a legacy sequencer
client, it's ignored or handled as an error.
Conceptually, ALSA sequencer client and port correspond to the UMP
Endpoint and Group, respectively; each client may have multiple ports
and each port has the fixed number (16) of channels, total up to 256
channels.
As of this commit, ALSA sequencer core just sends and receives the UMP
events as-is from/to clients. The automatic conversions between the
legacy events and the new UMP events will be implemented in a later
patch.
Along with this commit, bump the sequencer protocol version to 1.0.3.

This extends the ALSA sequencer port capability bit to indicate the
"inactive" flag. When this flag is set, the port is essentially
invisible, and doesn't appear in the port query ioctls, while the
direct access and the connection to this port are still allowed. The
active/inactive state can be flipped dynamically, so that it can be
visible at any time later.
This feature is introduced basically for UMP; some UMP Groups in a UMP
Block may be unassigned, hence those are practically invisible. On
ALSA sequencer, the corresponding sequencer ports will get this new
"inactive" flag to indicate the invisible state.

This is an extension to ALSA sequencer infrastructure to support the
MIDI 2.0 UMP Endpoint port. It's a "catch-all" port that is supposed
to be present for each UMP Endpoint. When this port is read via
subscription, it sends any events from all ports (UMP Groups) found in
the same client.
A UMP Endpoint port can be created with the new capability bit
SNDRV_SEQ_PORT_CAP_UMP_ENDPOINT. Although the port assignment isn't
strictly defined, it should be the port number 0.

Add a new field "direction" to snd_seq_port_info for allowing a client
to tell the expected direction of the port access. A port might still
allow subscriptions for read/write (e.g. for MIDI-CI) even if the
primary usage of the port is a single direction (either input or
output only). This new "direction" field can help to indicate such
cases.
When the direction is unspecified at creating a port and the port has
either read or write capability, the corresponding direction bits are
set automatically as default.

Add yet more new filed "ump_group" to snd_seq_port_info for specifying
the associated UMP Group number for each sequencer port. This will be
referred in the upcoming automatic UMP conversion in sequencer core.

This patch enables the automatic conversion of UMP events from/to the
legacy ALSA sequencer MIDI events. Also, as UMP itself has two
different modes (MIDI 1.0 and MIDI 2.0), yet another converters
between them are needed, too. Namely, we have conversions between the
legacy and UMP like:
- seq legacy event -> seq UMP MIDI 1.0 event
- seq legacy event -> seq UMP MIDI 2.0 event
- seq UMP MIDI 1.0 event -> seq legacy event
- seq UMP MIDI 2.0 event -> seq legacy event
and the conversions between UMP MIDI 1.0 and 2.0 clients like:
- seq UMP MIDI 1.0 event -> seq UMP MIDI 2.0 event
- seq UMP MIDI 2.0 event -> seq UMP MIDI 1.0 event
The translation is per best-effort; some MIDI 2.0 specific events are
ignored when translated to MIDI 1.0.

A sequencer client like seq_dummy rather doesn't want to convert UMP
events but receives / sends as is. Add a new event filter flag to
suppress the automatic UMP conversion and applies accordingly.

` (4 subsequent siblings)
35 siblings, 1 reply; 89+ messages in thread
From: Takashi Iwai @ 2023-05-19 9:31 UTC (permalink / raw)
To: alsa-devel; +Cc: linux-kernel
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.

From: Takashi Iwai @ 2023-05-19 9:31 UTC (permalink / raw)
To: alsa-devel; +Cc: linux-kernel
Create a sequencer port for broadcasting the all group inputs at the
port number 0. This corresponds to a UMP Endpoint connection;
application can read all UMP events from this port no matter which
group the UMP packet belongs to.
Unlike seq ports for other UMP groups, a UMP Endpoint port has no
SND_SEQ_PORT_TYPE_MIDI_GENERIC bit, so that it won't be treated as a
normal MIDI 1.0 device from legacy applications.
The port is named as "MIDI 2.0" to align with representations on other
operation systems.

Add new ioctls for sequencer clients to query and set the UMP endpoint
and block information.
As a sequencer client corresponds to a UMP Endpoint, one UMP Endpoint
information can be assigned at most to a single sequencer client while
multiple UMP block infos can be assigned by passing the type with the
offset of block id (i.e. type = block_id + 1).
For the kernel client, only SNDRV_SEQ_IOCTL_GET_CLIENT_UMP_INFO is
allowed.

This patch enhances the /proc/asound/seq/clients output to show a few
more information about the assigned UMP Endpoint and Blocks.
The "Groups" are shown in 1-based group number to align with the
sequencer client name and port number.

Add a new filter bitmap for UMP groups for reducing the unnecessary
read/write when the client is connected to UMP EP seq port.
The new group_filter field contains the bitmap for the groups, i.e.
when the bit is set, the corresponding group is filtered out and
the messages to that group won't be delivered.
The filter bitmap consists of each bit of 1-based UMP Group number.
The bit 0 is reserved for the future use.

+=================
+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.
+
+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 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 Group Terminal Block (GTB) in USB
+MIDI 2.0 specifications but provide a few more generic information.
+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
+ Client info
+ cur clients : 3
+ ....
+ Client 14 : "Midi Through" [Kernel Legacy]
+ Port 0 : "Midi Through Port-0" (RWe-)
+ Client 20 : "ProtoZOA" [Kernel UMP MIDI1]
+ UMP Endpoint: ProtoZOA
+ UMP Block 0: ProtoZOA Main [Active]
+ Groups: 1-1
+ UMP Block 1: ProtoZOA Ext IN [Active]
+ Groups: 2-2
+ UMP Block 2: ProtoZOA Ext OUT [Active]
+ Groups: 3-3
+ Port 0 : "MIDI 2.0" (RWeX) [In/Out]
+ Port 1 : "ProtoZOA Main" (RWeX) [In/Out]
+ Port 2 : "ProtoZOA Ext IN" (-We-) [Out]
+ Port 3 : "ProtoZOA Ext OUT" (R-e-) [In]
+
+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.
+
+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`.
+
+
+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.
+
+
+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 reserved for future use.
+
+* 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.

103 Each UMP Endpoint can provide the additional information, constructed
104 from USB MIDI 2.0 descriptors. And a UMP Endpoint may contain one or
105 more UMP Blocks, where UMP Block is an abstraction introduced in the
106 ALSA UMP implementations to represent the associations among UMP
107 Groups. UMP Block corresponds to Group Terminal Block (GTB) in USB
108 MIDI 2.0 specifications but provide a few more generic information.
109 The information of UMP Endpoints and UMP Blocks are found in the proc
110 file `/proc/asound/card*/midi*`. For example::
> 111 % cat /proc/asound/card1/midi0

I suspect that those two fields were added to enumerate devices in the control
API. But this extension seems to be missing in your patches. There is only
SNDRV_CTL_IOCTL_UMP_NEXT_DEVICE implemented. Otherwise those two fields are
not useful.
I also see the reference in the sequencer API
SNDRV_SEQ_IOCTL_GET_CLIENT_UMP_INFO, but I don't get the use there, too.

The SNDRV_CTL_IOCTL_UMP_NEXT_DEVICE is looping over rawmidi, and
snd_rawmidi_info is provided for (kernel) UMP implementation.
I took over those fields from snd_rawmidi_info, and they are supposed
to be referred rather from sequencer clients/ports (as well as from
the UMP rawmidi). Then it could be useful when a user-space sequencer
client implements the UMP in future, and distinguish its identity.
But, it's no big deal to drop those, too.
thanks,
Takashi

The internal struct snd_seq_event_cell is also extended by 4 bytes. I think
that it is worth to note this in this commit (the memory footprint is slightly
growing). Maybe handle !SND_UMP here, but we can wait, if someone really
requires this optimization.

Yes, will do that. But note that the size growth of
snd_seq_event_cell happens only for 32bit archs (there was already
padding on 64bit archs).

Right, I began with that, but I threw it away in the end as it becomes
unnecessarily complex.

Right. My point was that an application may be able to evaluate the other UMP
specific information from those new structures before the rawmidi device is
opened. So the CTL API extension may make sense.

Ok, keep them. Although this information seems to be redundant, it's harmless
for now.

Point taken, and indeed it might make more sense to change the ioctl
for looking at snd_ump_endpoint_info. Will try to cook with it.

Actually the optimization with CONFIG_SND_SEQ_UMP was already done;
unless CONFIG_SND_SEQ_UMP is set, the old size of snd_seq_event_cell
is still kept. The definition of union __snd_seq_event in
seq_memory.c takes care of the conditional builds.
What I meant was to adjust the cell size dynamically depending on the
supported midi_version, and this will make things too flaky.

FWIW, below is the patch to add two new ioctls for UMP EP/block
inquiries. It's together with a slight change of ioctl callback.
Will be included in v2 patch set I'll submit later.
The latest patches are found in topic/midi20 branch of sound git
tree.

Subject: [PATCH] ALSA: ump: Add ioctls to inquiry UMP EP and Block info via
control API
It'd be convenient to have ioctls to inquiry the UMP Endpoint and UMP
Block information directly via the control API without opening the
rawmidi interface, just like SNDRV_CTL_IOCTL_RAWMIDI_INFO.
This patch extends the rawmidi ioctl handler to support those; new
ioctls, SNDRV_CTL_IOCTL_UMP_ENDPOINT_INFO and
SNDRV_CTL_IOCTL_UMP_BLOCK_INFO, return the snd_ump_endpoint and
snd_ump_block data that is specified by the device field,
respectively.

Subject: [PATCH] ALSA: ump: Add ioctls to inquiry UMP EP and Block info via
control API
It'd be convenient to have ioctls to inquiry the UMP Endpoint and UMP
Block information directly via the control API without opening the
rawmidi interface, just like SNDRV_CTL_IOCTL_RAWMIDI_INFO.
This patch extends the rawmidi ioctl handler to support those; new
ioctls, SNDRV_CTL_IOCTL_UMP_ENDPOINT_INFO and
SNDRV_CTL_IOCTL_UMP_BLOCK_INFO, return the snd_ump_endpoint and
snd_ump_block data that is specified by the device field,
respectively.

The Endpoint Product ID is a string field and supposed to be unique. It's copied from `iSerialNumber` of the device for USB MIDI.
MIDI.ORG published an updated UMP specification today, dated June 15, 2023. Section 7.1.5 Adds the concept of Product Instance ID. Instead of returning the VID/PID, could this ID be returnedserial instead in the port data if it is available from the device ?

See the latest patch set for the new UMP 1.1 spec:
https://lore.kernel.org/r/20230612081054.17200-1-tiwai@suse.de
It's been already merged to sound git tree.
