ff39117fac ALSA: usb-audio: Improved lowlatency playback support
commit d5f871f89e21bb71827ea57bd484eedea85839a0 upstream.

This is another attempt to improve further the handling of playback
stream in the low latency mode.  The latest workaround in commit
4267c5a8f313 ("ALSA: usb-audio: Work around for XRUN with low latency
playback") revealed that submitting URBs forcibly in advance may
trigger XRUN easily.  In the classical mode, this problem was avoided
by practically delaying the submission of the actual data with the
pre-submissions of silent data before triggering the stream start.
But that is exactly what we want to avoid.

Now, in this patch, instead of the previous workaround, we take a
similar approach as used in the implicit feedback mode.  The URBs are
queued at the PCM trigger start like before, but we check whether the
buffer has been already filled enough before each submission, and
stop queuing if the data overcomes the threshold.  The remaining URBs
are kept in the ready list, and they will be retrieved in the URB
complete callback of other (already queued) URBs.  In the complete
callback, we try to fill the data and submit as much as possible
again.  When there is no more available in-flight URBs that may handle
the pending data, we'll check in PCM ack callback and submit and
process URBs there in addition.  In this way, the amount of in-flight
URBs may vary dynamically and flexibly depending on the available data
without hitting XRUN.

The following things are changed to achieve the behavior above:

* The endpoint prepare callback is changed to return an error code;
  when there is no enough data available, it may return -EAGAIN.
  Currently only prepare_playback_urb() returns the error.

  The evaluation of the available data is a bit messy here; we can't
  check with snd_pcm_avail() at the point of prepare callback (as
  runtime->status->hwptr hasn't been updated yet), hence we manually
  estimate the appl_ptr and compare with the internal hwptr_done to
  calculate the available frames.

* snd_usb_endpoint_start() doesn't submit full URBs if the prepare
  callback returns -EAGAIN, and puts the remaining URBs to the ready
  list for the later submission.

* snd_complete_urb() treats the URBs in the low-latency mode similarly
  like the implicit feedback mode, and submissions are done in
  (now exported) snd_usb_queue_pending_output_urbs().

* snd_usb_queue_pending_output_urbs() again checks the error value
  from the prepare callback.  If it's -EAGAIN for the normal stream
  (i.e. not implicit feedback mode), we push it back to the ready list
  again.

* PCM ack callback is introduced for the playback stream, and it calls
  snd_usb_queue_pending_output_urbs() if there is no in-flight URB
  while the stream is running.  This corresponds to the case where the
  system needs the appl_ptr update for re-submitting a new URB.

* snd_usb_queue_pending_output_urbs() and the prepare EP callback
  receive in_stream_lock argument, which is a bool flag indicating the
  call path from PCM ack.  It's needed for avoiding the deadlock of
  snd_pcm_period_elapsed() calls.

* Set the new SNDRV_PCM_INFO_EXPLICIT_SYNC flag when the new
  low-latency mode is deployed.  This assures catching each applptr
  update even in the mmap mode.

commit 0ef74366bc150dda4f53c546dfa6e8f7c707e087 upstream.

Although we have the state check beforehand, it's safer to apply
ep->lock during the critical list head manipulations.

31056232ad ALSA: usb-audio: Check available frames for the next packet size
commit d215f63d49da9a8803af3e81acd6cad743686573 upstream.

This is yet more preparation for the upcoming changes.

Extend snd_usb_endpoint_next_packet_size() to check the available
frames and return -EAGAIN if the next packet size is equal or exceeds
the given size.  This will be needed for avoiding XRUN during the low
latency operation.

As of this patch, avail=0 is passed, i.e. the check is skipped and no
behavior change.

8d7c6f515b ALSA: usb-audio: Disable low-latency mode for implicit feedback sync
commit bceee75387554f682638e719d1ea60125ea78cea upstream.

When a playback stream runs in the implicit feedback mode, its
operation is passive and won't start unless the capture packet is
received.  This behavior contradicts with the low-latency playback
mode, and we should turn off lowlatency_playback flag accordingly.

In theory, we may take the low-latency mode when the playback-first
quirk is set, but it still conflicts with the later operation with the
fixed packet numbers, so it's disabled all together for now.

2d9ea74b37 ALSA: usb-audio: Rename early_playback_start flag with lowlatency_playback
commit 9c9a3b9da891cc70405a544da6855700eddcbb71 upstream.

This is a preparation patch for the upcoming low-latency improvement
changes.

Rename early_playback_start flag with lowlatency_playback as it's more
intuitive.  The new flag is basically a reverse meaning.

Along with the rename, factor out the code to set the flag to a
function.  This makes the complex condition checks simpler.

Also, the same flag is introduced to snd_usb_endpoint, too, that is
carried from the snd_usb_substream flag.  Currently the endpoint flag
isn't still referred, but will be used in later patches.

commit 4e7cf1fbb34ecb472c073980458cbe413afd4d64 upstream.

When a single clock source is shared among several endpoints, we have
to keep the same rate on all active endpoints as long as the clock is
being used.  For dealing with such a case, this patch adds one more
check in the hw params constraint for the rate to take the shared
clocks into account.  The current rate is evaluated from the endpoint
list that applies the same clock source.

Stream IDs are reused across multiple BackEnd mixers, do not reset the

Ex:
amixer cset iface=MIXER,name='SLIMBUS_0_RX Audio Mixer MultiMedia1' 1

would set the MultiMedia1 steam for SLIMBUS_0_RX, however doing below
command will reset previously setup MultiMedia1 stream, because both of them
are using MultiMedia1 PCM stream.

amixer cset iface=MIXER,name='SLIMBUS_2_RX Audio Mixer MultiMedia1' 0

reset the FrontEnd Mixers conditionally to fix this issue.

This is more noticeable in desktop setup, where in alsactl tries to restore
the alsa state and overwriting the previous mixer settings.

[ Upstream commit fd572393baf0350835e8d822db588f679dc7bcb8 ]

If codec is in runtime suspend, but controller is not, hotplug events
are missed as the codec has no way to alert the controller. Problem does
not occur if both controller and codec are active, or when both are
suspended.

An easy way to reproduce is to play an audio stream on one codec (e.g.
to HDMI/DP display codec), wait for other HDA codec to go to runtime
suspend, and then plug in a headset to the suspended codec. The jack
event is not reported correctly in this case. Another way to reproduce
is to force controller to stay active with
"snd_sof_pci.sof_pci_debug=0x1"

Fix the issue by reconfiguring the WAKEEN register when powering up/down
individual links, and handling control events in the interrupt handler.

25aa8e9f10 ALSA: ctxfi: Fix out-of-range access
commit 76c47183224c86e4011048b80f0e2d0d166f01c2 upstream.

The master and next_conj of rcs_ops are used for iterating the
resource list entries, and currently those are supposed to return the
current value.  The problem is that next_conf may go over the last
entry before the loop abort condition is evaluated, and it may return
the "current" value that is beyond the array size.  It was caught
recently as a GPF, for example.

Those return values are, however, never actually evaluated, hence
basically we don't have to consider the current value as the return at
all.  By dropping those return values, the potential out-of-range
access above is also fixed automatically.

This patch changes the return type of master and next_conj callbacks
to void and drop the superfluous code accordingly.

The code for hdac_ext_stream seems inherited from hdac_stream, and

spinlock is inconsistent, with only writes to specific fields being

snd_hdac_ext_stream_decouple_locked() added to simplify code

330651b2c0 ASoC: DAPM: Cover regression by kctl change notification fix
commit 827b0913a9d9d07a0c3e559dbb20ca4d6d285a54 upstream.

The recent fix for DAPM to correct the kctl change notification by the
commit 5af82c81b2c4 ("ASoC: DAPM: Fix missing kctl change
notifications") caused other regressions since it changed the behavior
of snd_soc_dapm_set_pin() that is called from several API functions.
Formerly it returned always 0 for success, but now it returns 0 or 1.

This patch addresses it, restoring the old behavior of
snd_soc_dapm_set_pin() while keeping the fix in
snd_soc_dapm_put_pin_switch().

[ Upstream commit 28c369e60827f706cef4604a3e2848198f25bd26 ]

Behringer UFX1204 and UFX1604 have Synchronous endpoints to which
current ALSA code applies implicit feedback sync as if they were
Asynchronous endpoints. This breaks UAC compliance and is unneeded.

The commit 5e35dc0338d85ccebacf3f77eca1e5dea73155e8 and subsequent
1a15718b41df026cffd0e42cfdc38a1384ce19f9 were meant to clear up noise.

Unfortunately, noise persisted for those using higher sample rates and
this was only solved by commit d2e8f641257d0d3af6e45d6ac2d6f9d56b8ea964

Since there are no more reports of noise, let's get rid of the
implicit-fb quirks breaking UAC compliance.

e4fa14bdf8 ASoC: cs42l42: Correct configuring of switch inversion from ts-inv
[ Upstream commit 778a0cbef5fb76bf506f84938517bb77e7a1c478 ]

The setting from the cirrus,ts-inv property should be applied to the
TIP_SENSE_INV bit, as this is the one that actually affects the jack
detect block. The TS_INV bit only swaps the meaning of the PLUG and
UNPLUG interrupts and should always be 1 for the interrupts to have
the normal meaning.

Due to some misunderstanding the driver had been implemented to
configure the TS_INV bit based on the jack switch polarity. This made
the interrupts behave the correct way around, but left the jack detect
block, button detect and analogue circuits always interpreting an open
switch as unplugged.

The signal chain inside the codec is:

SENSE pin -> TIP_SENSE_INV -> TS_INV -> (invert) -> interrupts
                  |
                  v
             Jack detect,
          button detect and
            analog control

As the TIP_SENSE_INV already performs the necessary inversion the
TS_INV bit never needs to change. It must always be 1 to yield the
expected interrupt behaviour.

Some extra confusion has arisen because of the additional invert in the
interrupt path, meaning that a value applied to the TS_INV bit produces
the opposite effect of applying it to the TIP_SENSE_INV bit. The ts-inv
property has therefore always had the opposite effect to what might be
expected (0 = inverted, 1 = not inverted). To maintain the meaning of
the ts-inv property it must be inverted when applied to TIP_SENSE_INV.

[ Upstream commit cddcd5472abb7b8a9c37ccbcf0908b79740a01b5 ]

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.

b7e17c293e ASoC: cs42l42: Always configure both ASP TX channels
[ Upstream commit 6e6825801ab926360f7f4f2dbcfd107d5ab8f025 ]

An I2S frame always has two slots (left and right) even when sending
mono. The right channel (channel 2) of ASP TX will always have the
same bit width as the left channel and will always be on the high
phase of LRCLK.

The previous implementation always passed the field masks for both
channels to snd_soc_component_update_bits() but for mono the written value
only contained the settings for channel 1. The result was that for mono
channel 2 was set to 8-bit (which is an invalid configuration) with both
channels on the low phase of LRCLK.

784bf21bb6 ALSA: usb-audio: Fix possible race at sync of urb completions
[ Upstream commit 86a42ad07905110f82648853c0ea3434b4eab173 ]

USB-audio driver tries to sync with the clear of all pending URBs in
wait_clear_urbs(), and it waits for all bits in active_mask getting
cleared.  This works fine for the normal operations, but when a stream
is managed in the implicit feedback mode, there is still a very thin
race window: namely, in snd_complete_usb(), the active_mask bit for
the current URB is once cleared before re-submitted in
queue_pending_output_urbs().  If wait_clear_urbs() is called during
that period, it may pass the test and go forward even though there may
be a still pending URB.

For covering it, this patch adds a new counter to each endpoint to
keep the number of in-flight URBs, and changes wait_clear_urbs()
checking this number instead.  The counter is decremented at the end
of URB complete, hence the reference is kept as long as the URB
complete is in process.

34862fa65c ALSA: hda: Use position buffer for SKL+ again
[ Upstream commit c4ca3871e21fa085096316f5f8d9975cf3dfde1d ]

The commit f87e7f25893d ("ALSA: hda - Improved position reporting on
SKL+") changed the PCM position report for SKL+ chips to use DPIB, but
according to Pierre, DPIB is no best choice for the accurate position
reports and it often reports too early.  The recommended method is
rather the classical position buffer.

This patch makes the PCM position reporting on SKL+ back to the
position buffer again.

987bfc6eb7 ALSA: hda: Reduce udelay() at SKL+ position reporting
[ Upstream commit 46243b85b0ec5d2cee7545e5ce18c015ce91957e ]

The position reporting on Intel Skylake and later chips via
azx_get_pos_skl() contains a udelay(20) call for the capture streams.
A call for this alone doesn't sound too harmful.  However, as the
pointer PCM ops is one of the hottest path in the PCM operations --
especially for the timer-scheduled operations like PulseAudio -- such
a delay hogs CPU usage significantly in the total performance.

The code there was taken from the original code in ASoC SST Skylake
driver blindly.  The udelay() is a workaround for the case where the
reported position is behind the period boundary at the timing
triggered from interrupts; applications often expect that the full
data is available for the whole period when returned (and also that's
the definition of the ALSA PCM period).

OTOH, HD-audio (legacy) driver has already some workarounds for the
delayed position reporting due to its relatively large FIFO, such as
the BDL position adjustment and the delayed period-elapsed call in the
work.  That said, the udelay() is almost superfluous for HD-audio
driver unlike SST, and we can drop the udelay().

Though, the current code doesn't guarantee the full period readiness
as mentioned in the above, but rather it checks the wallclock and
detects the unexpected jump.  That's one missing piece, and the drop
of udelay() needs a bit more sanity checks for the delayed handling.

This patch implements those: the drop of udelay() call in
azx_get_pos_skl() and the more proper check of hwptr in
azx_position_ok().  The latter change is applied only for the case
where the stream is running in the normal mode without
no_period_wakeup flag.  When no_period_wakeup is set, it essentially
ignores the period handling and rather concentrates only on the
current position; which implies that we don't need to care about the
period boundary at all.

changed code paths causing broken headphones output. Pass WCD9335 instead of
WCD9335_VERSION_2_0 to wcd_clsh_ctrl_alloc to fix it.
