d4b8fc66f7 ALSA: usb-audio: Allow multiple entries for the same iface in composite quirk
Currently the composite quirk doesn't work when multiple entries are
assigned to the same interface because it marks the interface as
claimed then checks whether the interface has been already claimed for
the secondary entry.  But, if you look at the code, you'll notice that
multiple entries are allowed if the entry is the current interface;
i.e. the current behavior is anyway inconsistent, and this is an
unintended shortcoming.

This patch fixes the problem by marking the relevant interfaces as
claimed after applying the all composite entries.  This fix will be
needed for the upcoming enhancements for Digidesign Mbox 1 quirks.

The usb-audio driver detects XRUN at its complete callback, but the
actual code to trigger PCM XRUN is commented out because it caused
deadlock in the past.  This patch revives the PCM trigger properly.
It resulted in more than just enabling snd_pcm_stop(), but it had to
deduce the PCM substream with proper NULL checks and holds the stream
lock around the call.

 ---[ end trace 40b1928d1136b91e ]---

This comes from the fact that usb-audio driver may receive the
disconnect callback multiple times, per each usb interface.  When a
device has both audio and midi interfaces, it gets called twice, and
currently the driver tries to release resources at the last call.
At this point, the first parent interface has been already deleted,
thus deleting a child of the first parent hits such a warning.

For fixing this problem, we need to call snd_card_disconnect() and
cancel pending operations at the very first disconnect while the
release of the whole objects waits until the last disconnect call.

ea9d0d771f ASoC: dpcm: Fix race between FE/BE updates and trigger
DPCM can update the FE/BE connection states totally asynchronously
from the FE's PCM state.  Most of FE/BE state changes are protected by
mutex, so that they won't race, but there are still some actions that
are uncovered.  For example, suppose to switch a BE while a FE's
stream is running.  This would call soc_dpcm_runtime_update(), which
sets FE's runtime_update flag, then sets up and starts BEs, and clears
FE's runtime_update flag again.

When a device emits XRUN during this operation, the PCM core triggers
snd_pcm_stop(XRUN).  Since the trigger action is an atomic ops, this
isn't blocked by the mutex, thus it kicks off DPCM's trigger action.
It eventually updates and clears FE's runtime_update flag while
soc_dpcm_runtime_update() is running concurrently, and it results in
confusion.

Usually, for avoiding such a race, we take a lock.  There is a PCM
stream lock for that purpose.  However, as already mentioned, the
trigger action is atomic, and we can't take the lock for the whole
soc_dpcm_runtime_update() or other operations that include the lengthy
jobs like hw_params or prepare.

This patch provides an alternative solution.  This adds a way to defer
the conflicting trigger callback to be executed at the end of FE/BE
state changes.  For doing it, two things are introduced:

- Each runtime_update state change of FEs is protected via PCM stream
  lock.
- The FE's trigger callback checks the runtime_update flag.  If it's
  not set, the trigger action is executed there.  If set, mark the
  pending trigger action and returns immediately.
- At the exit of runtime_update state change, it checks whether the
  pending trigger is present.  If yes, it executes the trigger action
  at this point.

4c8c3a4fcc ALSA: usb-audio: Flatten probe and disconnect functions
The usb-audio probe and disconnect functions have been split just for
adapting the (new!) API at 2.5 kernel time.  We left them until now,
partly because we wanted to build with the pretty old kernels in the
external alsa-driver tree.  But the support of such old kernels has
been longly stopped, so it's good time to clean up this mess.

One good point by this cleanup is that now the probe function returns
a proper error code instead of only -EIO.

f5914908a5 ALSA: pcm: Replace PCM hwptr tracking with tracepoints
ALSA PCM core has a mechanism tracking the PCM hwptr updates for
analyzing XRUNs.  But its log is limited (up to 10) and its log output
is a kernel message, which is hard to handle.

In this patch, the hwptr logging is moved to the tracing
infrastructure instead of its own.  Not only the hwptr updates but
also XRUN and hwptr errors are recorded on the trace log, so that user
can see such events at the exact timing.

The new "snd_pcm" entry will appear in the tracing events:
  # ls -F /sys/kernel/debug/tracing/events/snd_pcm
  enable  filter  hw_ptr_error/  hwptr/  xrun/

The hwptr is for the regular hwptr update events.  An event trace
looks like:

  aplay-26187 [004] d..3  4012.834761: hwptr: pcmC0D0p/sub0: POS: pos=488, old=0, base=0, period=1024, buf=16384

"POS" shows the hwptr update by the explicit position update call and
"IRQ" means the hwptr update by the interrupt,
i.e. snd_pcm_period_elapsed() call.  The "pos" is the passed
ring-buffer offset by the caller, "old" is the previous hwptr, "base"
is the hwptr base position, "period" and "buf" are period- and
buffer-size of the target PCM substream.
(Note that the hwptr position displayed here isn't the ring-buffer
 offset.  It increments up to the PCM position boundary.)

The XRUN event appears similarly, but without "pos" field.
The hwptr error events appear with the PCM identifier and its reason
string, such as "Lost interrupt?".

The XRUN and hwptr error reports on kernel message are still left, can
be turned on/off via xrun_debug proc like before.  But the bit 3, 4, 5
and 6 bits of xrun_debug proc are dropped by this patch.  Also, along
with the change, the message strings have been reformatted to be a bit
more consistent.

Last but not least, the hwptr reporting is enabled only when
CONFIG_SND_PCM_XRUN_DEBUG is set.

e3a4bd5eec ALSA: pcm: Simplify snd_pcm_action_lock_irq()
The function snd_pcm_action_lock_irq() can be much simplified by
simply wrapping snd_pcm_action() with the stream lock.  This was
rather the original idea, but later it was open coded for
optimization.  However, looking at the optimization part closely, one
notices that the probability of the optimized path is quite low; in
normal situations, the linked stream action happens only for the
triggered substream, thus the operation becomes identical.  So the
code simplification has a clear win, especially because we have now
doubly codes for both atomic and non-atomic locks.

1df8874bfa ALSA: hda/realtek - Update Initial AMP for EAPD control
The default EAPD control uses verb command to control EAPD. Some codec
does not have verb command for EAPD. It needs to control by hidden
register.

This update will avoid wrong behavior for some codec.  This patch will
fix double setup for EAPD.  It just needs to turn on by one site for
verb command or hidden register controlled.

Detailed changes:
- alc889_coef_init() is replaced with alc_update_coef_idx() with a
  correct COEF value.
- for ALC262, ALC887 and ALC900, the EAPD setup via the hidden
  register is removed because this rather conflicts with the EAPD verb
  setup.
-  For ALC888-VC, also the hidden register access is removed in
  alc888_coef_init().
- Remove the dead #if 0 code for ALC267/ALC268.

eafe8404c1 ALSA: es1968: Replace timeval with ktime_t
es1968_measure_clock uses struct timeval, which on 32-bit systems will overflow
in 2038, leading to incorrect interpretation of time.This patch changes the
function to use ktime_t instead of struct timeval, which implies:
- no y2038: ktime_t uses a 64-bit datatype explicitly.
- efficent subtraction: The earlier version computes the difference in usecs
  while dealing with secs and nsecs. It requires checks to see if the nsecs of
  stop is less than start. This patch uses a direct subtract of ktime_t and
  converts to usecs.
- use of monotonic clock (ktime_get) over real time (do_gettimeofday),
  which simplifies timekeeping, as it does not have to deal with cases
  where stop_time is less than start_time.

1ffae3612f ASoC: Fix snd_soc_find_dai() matching component by name
Commit 14621c7e5e ("ASoC: Consolidate CPU and CODEC DAI lookup")
consolidated the lookup of CPU DAIs and CODEC DAIs into a single function.
When matching a component by name for CODEC DAIs the code previous to the
patch compared the name in the DAI link table with component->name. For CPU
DAIs the code compared to dev_name(component->dev). The newly introduced
function ended up using the later as well.

For most components dev_name(component->dev) and component->name are the
same. The main notable exception are I2C devices where the driver name and
the device name are concatenated to form the component name. By using
dev_name(component->dev) instead of component->name the patch broke the
matching of I2C CODECs by name.

This patch restores the original behavior by using component->name instead
of dev_name(component->dev). This will be safe even for CPU DAIs since for
CPU DAIs both are the same.

Fixes: 14621c7e5e ("ASoC: Consolidate CPU and CODEC DAI lookup")

3b70bdba2f ALSA: hda - Add workaround for CMI8888 snoop behavior
CMI8888 shows the stuttering playback when the snooping is disabled
on the audio buffer.  Meanwhile, we've got reports that CORB/RIRB
doesn't work in the snooped mode.  So, as a compromise, disable the
snoop only for CORB/RIRB and enable the snoop for the stream buffers.

The resultant patch became a bit ugly, unfortunately, but we still can
live with it.

=============================================================================

By looking at 2744 line, we can get that it's because regcache_rbtree_write()
would call kmalloc() with GFP flag if it couldn't find an existing block to
insert nodes while this kmalloc() call is inside a spin_lock_irq_save pair,
i.e. IRQs disabled.

Even though this may be a bug that should be fixed, I still try to send this
patch as a quick fix (work around) since it does no harm to assign default
values of every registers when using regcache.

  aplay:32536 map pfn RAM range req uncached-minus for [mem 0x21d500000-0x21d51ffff], got write-back

Until the issue is addressed in the core side, take back to the old
good way in PCM code only for x86.

fb54a645b2 ALSA: hda - Add missing terminating entry to SND_HDA_PIN_QUIRK macro
Without this terminating entry, the pin matching would continue
across random memory until a zero or a non-matching entry was found.

The result being that in some cases, the pin quirk would not be
applied correctly.

63825f3a87 ALSA: pcm: Disable mmap for known broken archs
Some architectures like PARISC is known not to support mmap properly
with the DMA buffer, where dma_mmap_coherent() returns -EINVAL
unconditionally.  From the API POV, we should rather drop the mmap
support there and expose it before the user-space tries to call mmap.

The patch contains again ugly ifdef's, unfortunately, as there is no
global flag indicating this.  Once when such macro is defined, we can
get rid of this instead.

dde1c652d7 ALSA: pcm: Fix false lockdep warnings
As PCM core handles the multiple linked streams in parallel, lockdep
gets confused (partly because of weak annotations) and spews the
false-positive warnings.  This hasn't been a problem for long time but
the latest PCM lock path update seems to have woken up a sleeping
dog.

Here is an attempt to paper over this issue: pass the lock subclass
just calculated from the depth in snd_pcm_action_group().  Also, a
(possibly) wrong lock subclass set in snd_pcm_action_lock_mutex() is
dropped, too.

Currently, it is only true when the ELD buffer contents have been

currently sent in such cases (such as when unplugging or replugging a
sink).

Fix the code to always set eld_changed if eld_valid value is changed,
and therefore to always send the change event when the user-visible
value changes.

d5129f33a0 Subject: ALSA: seq: Remove autoload locks in driver registration
Since we're calling request_module() asynchronously now, we can get
rid of the autoload lock in snd_seq_device_register_driver(), as well
as in the snd-seq driver registration itself.  This enables the
automatic loading of dependent sequencer modules, such as
snd-seq-virmidi from snd-emu10k1-synth.

68ab61084d ALSA: seq: bind seq driver automatically
Currently the sequencer module binding is performed independently from
the card module itself.  The reason behind it is to keep the sequencer
stuff optional and allow the system running without it (e.g. for using
PCM or rawmidi only).  This works in most cases, but a remaining
problem is that the binding isn't done automatically when a new driver
module is probed.  Typically this becomes visible when a hotplug
driver like usb audio is used.

This patch tries to address this and other potential issues.  First,
the seq-binder (seq_device.c) tries to load a missing driver module at
creating a new device object.  This is done asynchronously in a workq
for avoiding the deadlock (modprobe call in module init path).

This action, however, should be enabled only when the sequencer stuff
was already initialized, i.e. snd-seq module was already loaded.  For
that, a new function, snd_seq_autoload_init() is introduced here; this
clears the blocking of autoloading, and also tries to load all pending
driver modules.

95926035b1 ALSA: emu10k1: Fix deadlock in synth voice lookup
The emu10k1 voice allocator takes voice_lock spinlock.  When there is
no empty stream available, it tries to release a voice used by synth,
and calls get_synth_voice.  The callback function,
snd_emu10k1_synth_get_voice(), however, also takes the voice_lock,
thus it deadlocks.

The fix is simply removing the voice_lock holds in
snd_emu10k1_synth_get_voice(), as this is always called in the
spinlock context.
