Takashi Iwai [Tue, 1 Jun 2021 16:24:57 +0000 (18:24 +0200)]
ALSA: usb-audio: Reduce latency at playback start

USB-audio driver behaves a bit strangely for the playback stream --
namely, it starts sending silent packets at PCM prepare state while
the actual data is submitted at first when the trigger START is kicked
off.  This is a workaround for the behavior where URBs are processed
too quickly at the beginning.  That is, if we start submitting URBs at
trigger START, the first few URBs will be immediately completed, and
this would result in the immediate period-elapsed calls right after
the start, which may confuse applications.

OTOH, submitting the data after silent URBs would, of course, result
in a certain delay of the actual data processing, and this is rather
more serious problem on modern systems, in practice.

This patch tries to revert the workaround and lets the URB submission
starting at PCM trigger for the playback again.  As far as I've tested
with various backends (native ALSA, PA, JACK, PW), I haven't seen any
problems (famous last words :)

Note that the capture stream handling needs no such workaround, since
the capture is driven per received URB.

Takashi Iwai [Tue, 1 Jun 2021 16:24:55 +0000 (18:24 +0200)]
ALSA: usb-audio: Refactoring delay account code

The PCM delay accounting in USB-audio driver is a bit complex to
follow, and this is an attempt to improve the readability and provide
some potential fix.

Basically, the PCM position delay is calculated from two factors: the
in-flight data on URBs and the USB frame counter.  For the playback
stream, we advance the hwptr already at submitting URBs.  Those
"in-flight" data amount is now tracked, and this is used as the base
value for the PCM delay correction.  The in-flight data is decreased
again at URB completion in return.  For the capture stream, OTOH,
there is no in-flight data, hence the delay base is zero.

The USB frame counter is used in addition for correcting the current
position.  The reference frame counter is updated at each submission
and receiving time, and the difference from the current counter value
is taken into account.

In this patch, each in-flight data bytes is recorded in the new
snd_usb_ctx.queued field, and the total in-flight amount is tracked in
snd_usb_substream.inflight_bytes field, as the replacement of
last_delay field.

Note that updating the hwptr after URB completion doesn't work for
PulseAudio who tries to scratch the buffer on the fly; USB-audio is
basically a double-buffer implementation, hence the scratching the
buffer can't work for the already submitted data.  So we always update
hwptr beforehand.  It's not ideal, but the delay account should give
enough correctness.

ALSA: firewire-motu: sequence replay for source packet header

This commit takes ALSA firewire-motu driver to perform sequence replay for
media clock recovery.

Unlike the other types of device, the devices in MOTU FireWire series
require two levels of sequence replay; the sequence of the number of
data blocks per packet and the sequence of source packet header per data
block. The former is already cached by ALSA IEC 61883-1/6 packet streaming
engine and ready to be replayed. The latter is also cached by ALSA
firewire-motu driver itself with a previous patch. This commit takes
the driver to replay both of them from the caches.

The sequence replay is tested with below models:

 * 828 mkII
 * Traveler
 * UltraLite
 * 828 mk3 FireWire
 * 828 mk3 Hybrid (except for high sampling transfer frequency
 * UltraLite mk3 FireWire
 * 4pre
 * AudioExpress

Unfortunately, below models still don't generate better sound, requires
more work:

 * 8pre
 * 828 mk3 Hybrid at high sampling transfer frequency

As long as I know, MOTU protocol version 1 requires extra care of the
format of data block, thus below models are not supported yet in this
time:

 * 828
 * 896

ALSA: bebob: perform sequence replay for media clock recovery

This commit takes ALSA bebob driver to perform sequence replay for media
clock recovery.

Many users have reported discontinuity of data block counter field of CIP
header in tx packet from the devices based on BeBoB ASICs. In the worst
case, the device corrupts not to respond to any transaction, then generate
bus-reset voluntarily for recovery. The sequence replay for media clock
recovery is expected to suppress most of the problems.

In the beginning of packet streaming, the device transfers NODATA packets
for a while, then multiplexes any event and syt information. ALSA
IEC 61883-1/6 packet streaming engine has implementation for it to drop
the initial NODATA packets. It starts sequence replay when detecting any
event multiplexed to tx packets.

The sequence replay is tested with below models:

 * Focusrite Saffire
 * Focusrite Saffire LE
 * Focusrite Saffire Pro 10 I/O
 * Focusrite Saffire Pro 26 I/O
 * M-Audio FireWire Solo
 * M-Audio FireWire Audiophile
 * M-Audio Ozonic
 * M-Audio FireWire 410
 * M-Audio FireWire 1814
 * Edirol FA-66
 * ESI Quatafire 610
 * Apogee Ensemble
 * Phonic Firefly 202
 * Behringer F-Control Audio 610

Unfortunately, below models doesn't generate sound. This seems regression
introduced recent few years:

 * Stanton Final Scratch ScratchAmp at middle sampling transfer frequency
 * Yamaha GO44
 * Yamaha GO46
 * Terratec Phase x24

As I reported, below model has quirk of discontinuity:

 * M-Audio ProFire Lightbridge

DM1000/DM1100 ASICs in BeBoB solution are known to have bugs at switch of
sampling transfer frequency between low/middle/high rates. The switch
generates the similar problems about which I mention in the above. Some
vendors customizes firmware so that the switch of frequency is done in
vendor-specific registers, then restrict users to switch the frequency.

For example of Focusrite Saffire Pro 10 i/o and 26 i/o, users allows to
switch the frequency within the three steps; e.g. 44.1/48.0 kHz are
available at low step. Between the steps, extra operation is required and
it always generates bus-reset.

Another example of Edirol FA-66, users are prohibited to switch the
frequency by software. It's done by hardware switch and power-off.

I note that the sequence replay is not a solution for the ASIC bugs. Users
need to disconnect the device corrupted by the bug, then reconnect it to
refresh state machine inner the ASIC.

ALSA: dice: perform sequence replay for media clock recovery

This commit takes ALSA dice driver to perform sequence replay for media
clock recovery.

Unlike the other types of device, DICE-based devices interpret the value
of syt field of CIP header in rx packets as presentation time for audio
playback, thus it's required for driver to compute value for outgoing
packet adequate to the device. It's done by media clock recovery by
handling tx packets.

The device starts packet transmission immediately at operation to
GLOBAL_ENABLE thus on-the-fly mode is not required.

DICE ASICs supports several pairs of isochronous packet streams.
Actually, maximum two pairs of streams are supported by devices.
We have three cases regarding to the number of streams:

1. a pair of streams
2. two tx packet streams and one rx packet streams
3. one tx packet streams and two rx packet streams
4. two pair of streams

The decision of playback timing is slightly different in the four cases.

In the case 1, sequence replay in the pair results in suitable playback
timing.

In the case 2, sequence replay from the first tx packet stream to rx
packet stream results in suitable playback timing.

In the case 3, sequence replay from tx packet stream to all of rx packet
stream results in suitable playback timing. Furthermore, the cycle to
start receiving packets should be the same between all rx packet streams.

In the case 4, sequence replay in each pair results in suitable playback
timing. Furthermore, the cycle to start receiving packets should be the
same between all rx packet streams.

The sequence replay is tested with below models:

* For case 1:
  * TC Electronic Konnekt 24d (DiceII)
  * TC Electronic Konnekt 8 (DiceII)
  * TC Electronic Konnekt Live (DiceII)

ALSA: dice: wait just for NOTIFY_CLOCK_ACCEPTED after GLOBAL_CLOCK_SELECT operation

NOTIFY_CLOCK_ACCEPTED notification is always generated as a result of
GLOBAL_CLOCK_SELECT operation, however NOTIFY_LOCK_CHG notification
doesn't, as long as the selected clock is already configured. In the case,
ALSA dice driver waits so long. It's inconvenient for some devices to lock
to the sequence of value in syt field of CIP header in rx packets.

This commit wait just for NOTIFY_CLOCK_ACCEPTED notification by reverting
changes partially done by two commits below:

 * commit fbeac84dbe9e ("ALSA: dice: old firmware optimization for Dice notification")
 * commit aec045b80d79 ("ALSA: dice: change notification mask to detect lock status change")

I note that the successful lock to the sequence of value in syt field of
CIP header in rx packets results in NOTIFY_EXT_STATUS notification, then
EXT_STATUS_ARX1_LOCKED bit stands in GLOBAL_EXTENDED_STATUS register.
The notification can occur enough after receiving the batch of rx packets.
When the sequence doesn't include value in syt field of CIP header in rx
packets adequate to the device, the notification occurs again and the bit
is off.

empty packet or a NODATA packet in blocking transmission method of
IEC 61883-1/6. For sequence replay, the cycle is handled as receiving an
empty packet. Furthermore, it doesn't start packet transmission till
receiving any packet.

The sequence replay is tested with below models:

* Fireface 400
* Fireface 800
* Fireface 802

I note that it is better to initialize Fireface 400 in advance by

not by HOST LED on the device. Unless, the device often stops packet
