We don't need to change the numid at each time snd_ctl_rename_id() is called, as the control element size itself doesn't change. Let's keep the previous numid value. Along with it, add a note about calling this function only in the card init phase. Reviewed-by:

Takashi Iwai authored
Currently the read event packet size in snd_seq_read() is defined by client->midi_version value that is guaranteed to be zero if UMP isn't enabled. But the static analyzer doesn't know of the fact, and it still suspects as if it were leading to a potential overflow. Add the more explicit check of CONFIG_SND_SEQ_UMP to determine the aligned_size value for avoiding the confusion. Fixes: 46397622 ("ALSA: seq: Add UMP support") Reported-by:

The limits were appropriate only for the 2nd set. FWIW, the channel count 4 for the 2nd set is suspicious as well - at least P17V_PLAYBACK_FIFO_PTR actually has 8 channels, and comments on HCFG2 hint at that as well. But all bitmasks are documented only for 4 channels. Anyway, rectifying that is out of scope for this patch. Signed-off-by:

The 2nd register set belongs to the P16V chip (or embedded P17V module), so there is nothing to show when no such part is present. Gen2 E-MU cards have a P17V, but it's entirely unused, so we hide it there as well. Signed-off-by:

On SB cards the number of captured channels is derived from the voice mask mixer control. But for E-MU cards this wasn't actually "wired up", so changing the mask would simply mess up the recording. We could fix that, but the channel routing through the FPGA makes the masking redundant. So instead we hide the control, and let the user specify the PCM channel count the traditional way.

The hardware can deal with primes up to 7 and power-of-two multiples thereof; the limitation is reflected by the possible buffer sizes. Note that setting the voice mask will not allow more than 16 channels even on Sound Blaster Audigy anymore, as 32 seems a bit excessive (the code overall appears to think so, just not in this case).

We use independent voices for the channels, so we need to make an effort to ensure that they are actually in sync. The hardware doesn't provide atomicity, so we may need to retry a few times, due to NMIs, PCI contention, and the wrong phase of the moon. Solution inspired by kX-project. Signed-off-by:

For unclear reasons, the extra voice was set up with half the buffer size instead of the period size. Commit 27ae958c ("emu10k1 driver - add multichannel device hw:x,3 [2-8/8]") mentions half-loop interrupts, so maybe this was an artifact of an earlier iteration of the patch. While at it, also fix periods_min of the regular playback - one period makes just no sense. Signed-off-by:

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.

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. Reviewed-by:

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. Reviewed-by:

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. Reviewed-by:

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. Reviewed-by:

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.

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. Reviewed-by:
