986376b68d ALSA: hda/realtek - Enable mic-mute hotkey for several Lenovo AIOs
We have several Lenovo AIOs like M810z, M820z and M920z, they have
the same design for mic-mute hotkey and led and they use the same
codec with the same pin configuration, so use the pin conf table to
apply fix to all of them.

bbf8ff6b1d ALSA: hda/realtek - Fixup for HP x360 laptops with B&O speakers
Added a new helper file for these fixups due to requiring a huge number
of coefs being set to get the top speakers to work, as well as
setting pin 0x17 for the top speakers and the correct input source
of 0x17 for volume control

[ Note: this is a revised work based on Tom's fixup patch with the
  replacement of the full COEF tables provided by Realtek.
  Also, the fixup function has a proper HDA_FIXUP_ACT_* handling now.
  The credit for the new COEF table goes to Kailang  -- tiwai ]

This patch adds the mute LED control for HP Spectre x360 Kabylake
model.  The mute LED is controlled via VREF bits on NID 0x1b, so we
need a new fixup function.

Note that this doesn't fix the other issues like the missing speaker

f274baa49b ALSA: usb-audio: Allow non-vmalloc buffer for PCM buffers
Currently, USB-audio driver allocates the PCM buffer via vmalloc(), as
this serves merely as an intermediate buffer that is copied to each
URB transfer buffer.  This works well in general on x86, but on some
archs this may result in cache coherency issues when mmap is used.
OTOH, it works also on such arch unless mmap is used.

This patch is a step for mitigating the inconvenience; a new module
option "use_vmalloc" is provided so that user can choose to allocate
the DMA coherent buffer instead of the existing vmalloc buffer.
The drawback is that it'd be the standard dma_alloc_coherent() calls
and the system would require contiguous pages on non-x86 archs.

Note that it's a global option and not dynamically switchable since
the buffer is pre-allocated at the probe time.  In theory, it's
possible to be switchable, but it'd be trickier and racier.

As default use_vmalloc option is set to true, so that the old behavior
is kept.  For allowing the coherent mmap on ARM or MIPS, pass
use_vmalloc=0 option explicitly.

014cea591a ALSA: xen-front: fix unsigned error check on return from to_sndif_format
The negative error return from the call to to_sndif_format is being
assigned to an unsigned 8 bit integer and hence the check for a negative
value is always going to be false.  Fix this by using ret as the error
return and hence the negative error can be detected and assign
the u8 sndif_format to ret if there is no error.

84eaaef2ae ALSA: dice: unuse second stream for MIDI conformant data channel for TC Electronic models
At present, all of models produced by TC Electronic except for Konnekt Live
are supported with hard-coded their stream formats. Studio Konnekt 48 is
sore model to support dual streams for both directions. The second stream
has no MIDI conformant data channel in its data block. But current
implementation transfers the second stream with MIDI conformant data
channel.

1ceb506d63 ALSA: dice: fix stream format parameters for TC Electronic Studio Konnekt 48
TC Electronic Studio Konnekt 48 is an application of combination of
WaveFront Dice II STD and TC Applied Technologies (TCAT) TCD2210 (Dice
Mini). The latter is on a board with BNC and optical interfaces, thus
used for signal processing for word clock, S/PDIF and ADAT. This model
doesn't support TCAT extended application protocol. For such devices,
ALSA dice driver needs to have hard-coded parameters for stream formats.

This commit fixes stream format parameters for this model. Unfortunately, at
sampling transmission frequencies over 48.0kHz, I confirmed that current
ALSA dice driver doesn't drive the device appropriately to generate sounds
(silence). I guess that this comes from timestamping quirk of Dice-based
devices, which I reported.

TC Electronic Digital Konnekt x32 is an application of WaveFront DiceII STD

ALSA dice driver needs to have hard-coded parameters for stream formats.

This commit adds stream format parameters for this model. Unfortunately, at

ALSA dice driver doesn't drive the device appropriately due to detecting
packet discontinuities.

At the frequencies, the device transfers 16 data blocks per packet and 16
data channels per data block, as a result one packet includes 1032 bytes
if it's not NODATA. However, as long as I checked, the device often
postpone packet transmission and continue with truncated payload than
metadata in isochronous packet header. Below is a sample of sequence I got.

I cannot confirm this quirks with Windows driver. ALSA dice driver has a
cause if assumed differences between these two drivers are ways of
timestampling to RX packets from the drivers to the device. I've already
reported timestamping quirk of Dice-based devices and this might bring
this issue.

[alsa-devel] Dice packet sequence quirk and ALSA firewire stack in Linux 4.6
http://mailman.alsa-project.org/pipermail/alsa-devel/2016-May/107715.html

Well, nevertheless, I enable ALSA dice driver to work at the frequencies.
This may brings inconvenience to users but I expect developers and users
to fix it.

--nextPart3916812.EicPReet6m
Content-Transfer-Encoding: 7Bit
Content-Type: text/plain; charset="us-ascii"

Mytek manufactures some equipment with DICE-based firewire ports. These
devices contain old versions of DICE firmware which lacks detailed
stream format reporting for all sampling clock modes.

Building upon the recent work by Takashi Sakamoto, hard-coded parameters
are added for the Stereo 192 DSD-DAC. When the device vendor and model
match the coded parameters are copied into the stream format cache.

9d4d207d13 ALSA: timer: Assure timer resolution access always locked
There are still many places calling the timer's hw.c_resolution
callback without lock, and this may lead to some races, as we faced in
the commit a820ccbe21 ("ALSA: pcm: Fix UAF at PCM release via PCM
timer access").

This patch changes snd_timer_resolution() to take the timer->lock for
avoiding the races.  A place calling this function already inside the
lock (from the notifier) is replaced with the
snd_timer_hw_resolution() accordingly, as well as wrapping with the
lock around another place calling snd_timer_hw_resolution(), too.

21244e3d6a ALSA: seq: Avoid open-code for getting timer resolution
Instead of open-coding for getting the timer resolution, use the
standard snd_timer_resolution() helper.

The original code falls back to the callback function when the
resolution is zero, but it must be always so when the callback
function is defined.  So this should be no functional change.

dc82e52492 ALSA: core: Assure control device to be registered at last
The commit 289ca025ee ("ALSA: Use priority list for managing device
list") changed the way to register/disconnect/free devices via a
single priority list.  This helped to make behavior consistent, but it
also changed a slight behavior change: namely, the control device is
registered earlier than others, while it was supposed to be the very
last one.

I've put SNDRV_DEV_CONTROL in the current position as the release of
ctl elements often conflict with the private ctl elements some PCM or
other components may create, which often leads to a double-free.
But, the order of register and disconnect should be indeed fixed as
expected in the early days: the control device gets registered at
last, and disconnected at first.

This patch changes the priority list order to move SNDRV_DEV_CONTROL
as the last guy to assure the register / disconnect order.  Meanwhile,
for keeping the messy resource release order, manually treat the
control and lowlevel devices as last freed one.

Additional note:
The lowlevel device is the device where a card driver creates at
probe.  And, we still keep the release order control -> lowlevel, as
there might  be link from a control element back to a lowlevel object.

Implement essential initialization of the sound driver:
  - introduce required data structures
  - handle driver registration
  - handle sound card registration
  - register sound driver on backend connection
  - remove sound driver on backend disconnect

Initialize virtual sound card with streams according to the
Xen store configuration.

Implement ALSA driver operations including:
  - manage frontend/backend shared buffers
  - manage Xen bus event channel states

Implement requests from front to back for ALSA
PCM operations.
  - report ALSA period elapsed event: handle XENSND_EVT_CUR_POS
    notifications from the backend when stream position advances
    during playback/capture. The event carries a value of how
    many octets were played/captured at the time of the event.
  - implement explicit stream parameter negotiation between
    backend and frontend: handle XENSND_OP_HW_PARAM_QUERY request
    to read/update configuration space for the parameter given:
    request passes desired parameter interval and the response to
    this request returns min/max interval for the parameter to be used.
