The OSS sequencer client tries to drain the pending events at
releasing. Unfortunately, as spotted by syzkaller fuzzer, this may
lead to an unkillable process state when the event has been queued at
the far future. Since the process being released can't be signaled
any longer, it remains and waits for the echo-back event in that far
future.
Back to history, the draining feature was implemented at the time we
misinterpreted POSIX definition for blocking file operation.
Actually, such a behavior is superfluous at release, and we should
just release the device as is instead of keeping it up forever.
This patch just removes the draining call that may block the release
for too long time unexpectedly.

This commit drops implementation of duplex streams synchronization
from ALSA dice driver, due to a reason of hardware design. This patch
allows dice-based units to generate sounds correctly when isochronous
packet streaming starts at first time.
In IEC 61883-6:2005, CIP packetization layer for AM824 data format
utilizes the value of SYT field in CIP header of received packet for
a reference to phase lock loop. Figure 3 in clause 4.3 describes it.
The value is an offset from cycle_time field of every cycle start packet
from cycle master on IEEE 1394 bus. The time calculated with these two
fields is called as 'presentation timestamp' which represents the time
to play data included in the packet.
Although, this idea includes some problems due to accuracy of timekeep in
cycle master, accuracy of transmission of cycle start packet on the bus
with the other units, accuracy of sampling clock in data transmitter side
and accuracy of replay in data receiver side. In most case, these
accuracies somewhat worse because there's no such ideal hardwares in this
world.
For the issues, ASICs for Dice include Jitter Elimination Technologies
(JET) PLL. The PLL can handle several sources of clock and compensate it
with high-precision internal clock source. The sequence of value in syt
field of received AMDTP packets is one of the sources, therefore
transmitters on IEEE 1394 bus should transfer it.
On the other hand, current ALSA dice driver is programmed with a mode of
duplex streams with synchronization. In this mode, the driver outputs
packets after some incoming packets are handled, to re-use the value of
SYT field in incoming packets to the value for outgoing packets. This mode
is enabled when source signal of sampling clock is set to internal, and
this is a major use case. Thus, in most cases, the unit receives no packets
during a short time after packet streaming starts.
As long as I experienced, this causes the units to generate no sounds at
first time to receive packets. This issue occurs only with Dice II. I guess
this is due to a quirk of the PLL. In short, the PLL cannot generate firm
signals to ADCs/DACs or the other ICs when no packets are received in the
beginning of packet streaming. While, on second time or later, the unit
generates sound correctly. I guess that starting packet streaming at first
time sets the PLL correctly.
Well, still based on my hypothesis and no way to prove it, this commit
drops duplex streams synchronization from this driver. At least, the PLL
requires the sequence of value in SYT field of received AMDTP packets as
one of source of clock signals with internal clock source.

Currently the interrupt handler of HD-audio driver assumes that no irq
update is needed while processing the irq. But in reality, it has
been confirmed that the HW irq is issued even during the irq
handling. Since we clear the irq status at the beginning, process the
interrupt, then exits from the handler, the lately issued interrupt is
left untouched without being properly processed.
This patch changes the interrupt handler code to loop over the
check-and-process. The handler tries repeatedly as long as the IRQ
status are turned on, and either stream or CORB/RIRB is handled.
For checking the stream handling, snd_hdac_bus_handle_stream_irq()
returns a value indicating the stream indices bits. Other than that,
the change is only in the irq handler itself.

In this case, MIDI substream should be terminated.
This commit stops MIDI transmission after the fatal error occurs.
Unfortunately, unlike ALSA PCM functionality, ALSA rawmidi core has no
feature to discontinue MIDI substream runtime in kernel side, thus this
commit just stops MIDI transmission without notifying it to userspace.

Currently, ALSA oxfw driver has a TODO to retry MIDI transferring
at transaction failure.
This commit achieves it. Current implementation uses snd_rawmidi_transmit()
to transfer messages, thus the target MIDI messages are not in buffer when
transaction failure is detected. Although we cannot use a pair of
snd_rawmidi_transmit_peek() and snd_ramwidi_transmit_ack(), the
messages are still in scs1x specific structure and the data is available
for retries.
This commit adds a member to the structure for the length of buffered
messages, and uses the value again at retries.

Since the recent integration of kctl jack and input jack layers, we
can basically build the jack layer even without input devices. That
is, the jack layer itself can be built with conditional to enable the
input device support or not, while the users may enable always
CONFIG_SND_JACK unconditionally.
For achieving it, this patch changes the following:
- A new Kconfig, CONFIG_SND_JACK_INPUT_DEV, was introduced to indicate
whether the jack layer supports the input device,
- A few items in snd_jack struct and relevant codes are conditionally
built upon CONFIG_SND_JACK_INPUT_DEV,
- The users of CONFIG_SND_JACK drop the messy dependency on
CONFIG_INPUT.
This change also automagically fixes a potential bug in HD-audio
driver Arnd reported, where the NULL or uninitialized jack instance is
dereferenced.

hdaudio hdaudioC0D2: no AFG or MFG node found
snd_hda_intel 0000:00:1f.3: no codecs initialized
Also, HP G470 G3 suffers from the similar problem, as reported in
bugzilla below. On this machine, the codec probe error appears even
at a fresh boot.
As Libin suggested, the same workaround used for Broxton in the commit
[6639484dda: ALSA: hda - disable dynamic clock gating on Broxton
before reset] can be applied for Skylake in order to fix this problem.
The Intel HW team also confirmed that this is needed for SKL.
This patch makes the workaround applied to both SKL and BXT
platforms. The referred macros are moved and one superfluous macro
(IS_BROXTON()) is another one (IS_BXT()) as well.

In IEC 61883-1, at bus-reset, applications can continue isochronous
streaming by updating connections. In ALSA fireworks driver, the
operation is executed in 'update' handler for bus driver.
The connection resources are also changed in process contexts of PCM/MIDI
applications. Therefore, bus-reset handling has race condition
against connection. Current ALSA fireworks driver has a bug for the
condition.
This commit fixes the bug, by expand critical section with mutex. As a
result, connection updating operation in bus-reset handler and connection
changing operation in process context are serialized.

At bus-reset, DM1000/DM1100/DM1500 chipsets transfer packets with
discontinuous value in 'dbc' field of CIP header. In this case, packet
streaming layer in firewire-lib module stops streaming and set XRUN to PCM
substream.
In ALSA, PCM applications are notified the XRUN status by the return value
of ALSA PCM interface. They can recover this state by executing
snd_pcm_prepare(), then PCM drivers' prepare handler is called, and start
new PCM substream. For ALSA BeBoB driver, the handler establishes new
connections and start new AMDTP streaming.
Unfortunately, neither the PCM applications nor the driver know the reason
of XRUN. The driver gets to know the reason when update handler is called
by IEEE 1394 bus driver. As long as I tested, the order of below events are
not fixed:
* Detecting packet discontinuity in tasklet context of OHCI 1394 driver
* Calling prepare handler in process context of ALSA PCM application
* Calling update handler in kthread context of IEEE 1394 bus driver
The unpredictable order is disadvantage for the driver to be compliant to
CMP. In IEC 61883-1, new CMP establish operations should be done 1 sec
(isoc_resource_delay) after bus-reset. Within 1 sec, CMP restore
operations are allowed. For this reason, in former commit ('b6bc812327aa:
ALSA: bebob/firewire-lib: Add a quirk for discontinuity at bus reset'),
the process context is forced to wait for executing update handler. The
process context wait for bus-reset up to 1 sec. This commit solves the
issue, while causes more disadvantages. For PCM applications, calling
snd_pcm_prepare() for recovering XRUN state takes more time and the driver
got a bit complicated code, while the recovery is not always successful.
As long as I tested, DM1000/DM1100/DM1500 and BeBoB firmware can allow
drivers to establish new connections just after bus reset. Furthermore,
any FCP transactions are handled correctly. Therefore, the driver don't
need to wait for bus reset handler for starting new streaming.
This commit removes the codes to reduce maintenance cost.

This commit replaces tasklet with workqueue for scs1x functionality of

This driver transfers MIDI message specific for SCS.1m and SCS.1d. This
task is currently done in software IRQ context of tasklet. In a view of
system, this context is limited resources and some important drivers (at
least, more important than ALSA oxfw driver) use the context as its
bottom-harf.
If the work to transfer MIDI messages is done within a time, it's better
to use the other context for the work. Actually, with recent CPUs, the
work will be scheduled within a time. This is a reason of this commit.

A non-atomic PCM stream may take snd_pcm_link_rwsem rw semaphore twice
in the same code path, e.g. one in snd_pcm_action_nonatomic() and
another in snd_pcm_stream_lock(). Usually this is OK, but when a
write lock is issued between these two read locks, the problem
happens: the write lock is blocked due to the first reade lock, and
the second read lock is also blocked by the write lock. This
eventually deadlocks.
The reason is the way rwsem manages waiters; it's queued like FIFO, so
even if the writer itself doesn't take the lock yet, it blocks all the
waiters (including reads) queued after it.
As a workaround, in this patch, we replace the standard down_write()
with an spinning loop. This is far from optimal, but it's good
enough, as the spinning time is supposed to be relatively short for
normal PCM operations, and the code paths requiring the write lock
aren't called so often.

This patch removes the static modelling of widget/route and
creates it dynamically based on the codec widgets enumerated.
Mux widgets are added to represent the map between a cvt and pin.
Ideally the mux widgets should be created based on the connection
list queried from the pin widget. But due to HW behavior, if an
external display is not connected on a port, querying the
connection list returns zero. So create mux widgets to map all
the cvt to all pins. At runtime, playback support on a pin can be
verified based on the connection list query.

When multiple concurrent writes happen on the ALSA sequencer device
right after the open, it may try to allocate vmalloc buffer for each
write and leak some of them. It's because the presence check and the
assignment of the buffer is done outside the spinlock for the pool.
The fix is to move the check and the assignment into the spinlock.
(The current implementation is suboptimal, as there can be multiple
unnecessary vmallocs because the allocation is done before the check
in the spinlock. But the pool size is already checked beforehand, so
this isn't a big problem; that is, the only possible path is the
multiple writes before any pool assignment, and practically seen, the
current coverage should be "good enough".)
The issue was triggered by syzkaller fuzzer.

Dice interface design doesn't allow drivers to read supported combination
between sampling transfer frequencies and the number of Multi bit linear
audio data channels. Due to the design, ALSA dice driver changes current
sampling transfer frequency to generate cache of the combinations at
device probing processing.
Although, this idea is worse because ALSA dice driver changes the state of
clock. This is not what users want when they save favorite configuration
to the device in advance.
Furthermore, there's a possibility that the format of data block is decided
not only according to current sampling transfer frequency, but also the
other factors, i.e. data format for digital interface. It's not good to
generate channel cache according to the sampling transfer frequency only.
This commit purges processing cache data and related structure members. As
a result, users must set preferable sampling transfer frequency before
using ALSA PCM applications, as long as they want to start any PCM
substreams at the rate except for current one.
