ALSA fireworks driver has a bug in its initial state to return count
shorter than expected by 4 bytes to userspace applications when handling
response frame for Echo Audio Fireworks transaction. It's due to missing
addition of the size for the type of event in ALSA firewire stack.

AV/C deferred transaction was supported at a commit 00a7bb81c20f ("ALSA:
firewire-lib: Add support for deferred transaction") while 'deferrable'
flag can be uninitialized for non-control/notify AV/C transactions.

This commit fixes the bug. The bug has no disadvantage for the non-

response with INTERIM (0x0f) status which is not used for the transactions
in AV/C general specification.

Loud Technologies shipped Onyx 1200f 2008 in its Mackie brand and
already discontinued. The model uses component of Fireworks board
module as its communication and DSP function.
The latest firmware (v4.6.0) has a quirk that tx packet includes wrong
value (0x1f) in its dbs field at middle and higher sampling transfer
frequency. It brings ALSA fireworks driver discontinuity of data block
counter.
This commit fixes it by assuming it as a quirk of firmware version
4.6.0.

A user reports functional regression for Mackie Onyx 1640i that the device
generates slow sound with ALSA oxfw driver which supports media clock
recovery. Although the device is based on OXFW971 ASIC, it does not
transfer isochronous packet with own event frequency as expected. The
device seems to adjust event frequency according to events in received
isochronous packets in the beginning of packet streaming. This is
unknown quirk.
This commit fixes the regression to turn the recovery off in driver
side. As a result, nominal frequency is used in duplex packet streaming
between device and driver. For stability of sampling rate in events of
transferred isochronous packet, 4,000 isochronous packets are skipped
in the beginning of packet streaming.

In command DSP models, one meter information consists of 4 bytes for
IEEE 764 floating point (binary32). In previous patch, it is exported
to userspace as 32 bit storage since the storage is also handled in
ALSA firewire-motu driver as well in kernel space in which floating point
arithmetic is not preferable. On the other hand, ALSA firewire-motu driver
doesn't perform floating point calculation. The driver just gather meter
information from isochronous packets and fill structure fields for
userspace.
In 'header' target of Kbuild, UAPI headers are processed before installed.
In this timing, #ifdef macro with __KERNEL__ is removed. This mechanism
is useful in the case so that the 32 bit storage can be accessible as u32
type in kernel space and float type in user space. We can see the same
usage in ''struct acct_v3' in 'include/uapi/linux/acct.h'.
This commit is for the above idea. Additionally, due to message
protocol, meter information is filled with 0xffffffff in the end of
period but 0xffffffff is invalid as binary32. To avoid confusion in
userspace application, the last two elements are left without any
assignment.

After further investigation, I realize that the total number of elements
in array is not enough to store all of related messages from device.
This commit refines meter array and message parser.
In terms of channel identifier, register DSP models are classified to
two categories:
1. the target of output is selectable
828mk2, 896hd, and Traveler are in the category. They transfer messages
with channel identifier between 0x00 and 0x13 for input meters,
therefore 20 elements are needed to store.
On the other hand, they transfer messages with channel identifier for one
pair of output meters. The selection is done by asynchronous write
transaction to offset 0x'ffff'f000'0b2c. The table for relationship
between written value and available identifiers is below:
============= ===============
written value identifier pair
============= ===============
0x00000b00 0x80/0x81
0x00000b01 0x82/0x83
... ...
0x00000b0b 0x96/0x97
... ...
0x00000b10 0xa0/0xa1
... ...
0x00000b3f 0xfe/0xff
... ...
greater 0xfe/0xff
============= ===============
Actually in the above three models, 0x96/0x97 pair is the maximum. Thus
the number of available output meter is 24.
2. all of output is available
8 pre, Ultralite, Audio Express, and 4 pre are in the category. They
transfer messages for output meters without any selection. The table for
available identifier for each direction is below:
============== ========= ==========
model input output
============== ========= ==========
8 pre 0x00-0x0f 0x82-0x8d
Ultralite 0x00-0x09 0x82-0x8f
Audio Express 0x00-0x09 0x80-0x8d
4 pre 0x00-0x09 0x80-0x8d
============== ========= ==========
Some of available identifiers might not be used for actual output meters.
Anyway, 24 plus 24 elements accommodate the input/output meters.
I note that isochronous packet from V3HD/V4HD deliver no message.
Notification by asynchronous transaction to registered address seems to be
used for the purpose as well as for change of mixer parameter.

character device
ALSA firewire-motu driver recently got support for event notification via
ALSA HwDep interface for register DSP models. However, when polling ALSA
HwDep cdev, the driver can cause null pointer dereference for the other
models due to accessing to unallocated memory or uninitialized memory.
This commit fixes the bug by check the type of model before accessing to
the memory.

In MOTU protocol v2/v3, first two data chunks across 2nd and 3rd data
channels includes message bytes from device. The total size of message
is 48 bits per data block.
The 'data_block_message' tracepoints event produced by ALSA firewire-motu
driver exposes the sequence of messages to userspace in 64 bit storage,
however lower 32 bits are actually available since current implementation
truncates 16 bits in upper of the message as a result of bit shift
operation within 32 bit storage.
This commit fixes the bug by perform the bit shift in 64 bit storage.

Loud Technologies Mackie Onyx 1640i (former model) is identified as
the model which uses OXFW971. The analysis of packet dump shows that
it transfers events in blocking method of IEC 61883-6, however the
default behaviour of ALSA oxfw driver is for non-blocking method.
This commit adds code to detect it assuming that all of loud models
based on OXFW971 have such quirk. It brings no functional change
except for alignment rule of PCM buffer.

Mark of the Unicorn (MOTU) shipped 896HD 2003 as one of models in second
generation of its FireWire series, and already discontinued it. The model
consists of below ICs:
* Texas Instruments TSB41AB2
* Phillips Semiconductors PDI1394L40
* Altera cyclone EP1C3
* Texas Instruments TMS320VC5402
It supports sampling transmission frequency up to 192.0 kHz. The packet
format differs depending on both of sampling transfer frequency and enabling
ADAT channels. The model doesn't support MIDI message transmission.
This commit adds support for it.

OXFW 971 has no function to use the value in syt field of received
isochronous packet for playback timing generation. In kernel prepatch for
v5.14, ALSA OXFW driver got change to send NO_INFO value in the field
instead of actual timing value. The change brings Apogee Duet FireWire to
generate no playback sound, while output meter moves.
As long as I investigate, _any_ value in the syt field takes the device to
generate sound. It's reasonable to think that the device just ignores data
blocks in packet with NO_INFO value in its syt field for audio data
processing.
This commit adds a new flag for the quirk to fix regression.

ALSA bebob driver has duplicated entries for modalias of
'ieee1394:ven00000AACmo00000002sp0000A02Dver00010001' since entries for
two devices below have the same parameters:
* Acoustic Reality eAR Master One, Eroica, Figaro, and Ciaccona
* TerraTec Aureon 7.1 FireWire
I relied on FFADO revision 737 to add the former entry, on the other hand,
the latter is based on message posted by actual user with information of
sysfs node:
* https://sourceforge.net/p/ffado/mailman/ffado-user/thread/5743F969.2080204%40marcobaldo.ch/
It appears that they have OUI of Terratec Electronic GmbH (0x000aac) and
the same model ID, thus suffice to say that they have something common
in their internals.
Although it's not going to make a big difference, this commit arranges
the entries.

A user of FFADO project reported the issue of ToneWeal FW66. As a result,
the device is identified as one of applications of BeBoB solution.
I note that in the report the device returns contradictory result in plug
discovery process for audio subunit. Fortunately ALSA BeBoB driver doesn't
perform it thus it's likely to handle the device without issues.
I receive no reaction to test request for this patch yet, however it would
be worth to add support for it.

is different. MOTU 828 mk3 Hybrid has additional 4 dummy data chunks for
rx packet.

MOTU 896 is a second model in MOTU FireWire series, produced in 2001. This
model consists of three chips:
* Texas Instruments TSB41AB2 (Physical layer for IEEE 1394 bus)
* Philips Semiconductors PDI 1394L21BE (Link layer for IEEE 1394 bus and
packet processing layer)
* QuickLogic QuickRAM QL4016 (Data block processing layer and digital
signal processing)
This commit adds a support for the model, with its unique protocol as
version 1. The features of this protocol are:
* no MIDI support.
* Rx packets have no data chunks for control and status messages.
* Tx packets have 2 bytes for control and status messages in the end of
each data block.
* The most of settings are represented in bit flag in one quadlet address
(0x'ffff'f000'0b14).
* It's selectable to use signal on optical interface, however the device
has no register specific to it. The state has effect just to whether
to exclude differed data chunks.
* The internal multiplexer is not configured by software.
Just after powering on, the device has a quirk to fail handling
transaction. I recommend users to connect the device enough after powering
on.

MOTU 828 is a first model in MOTU FireWire series, produced in 2001. This
model consists of three chips:
* Texas Instruments TSB41AB1 (Physical layer for IEEE 1394 bus)
* Philips Semiconductors 1394L21BE (Link layer for IEEE 1394 bus and
packet processing layer)
* QuickLogic QuickRAM QL4016 (Data block processing layer and digital

This commit adds a support for this model, with its unique protocol as
version 1. The features of this protocol are:
* no MIDI support.
* Rx packets have no data chunks for control and status messages.
* Tx packets have 2 data chunks for control and status messages in the
end of each data block. The chunks consist of data block counter
(4 byte) and message (2 byte).
* All of settings are represented in bit flag in one quadlet address
(0x'ffff'f000'0b00).
* When optical interface is configured as S/PDIF, signals of the interface
is multiplexed for packets, instead of signals of coaxial interface.
* The internal multiplexer is not configured by software.
I note that the device has a quirk to mute output voluntarily during
receiving batch of packets in the beginning of packet streaming. The
operation to unmute should be done by software enough after the device
shifts the state, however it's not deterministic. Furthermore, just
after switching rate of sampling clock, the device keeps the state longer.
This patch manages to sleep 100 msec before unmute operation, but it may
fail to release the mute in the case that the rate is changed. As a
workaround, users can restart packet streaming at the same rate, or write
to specific register from userspace.
