d9c5252295 treewide: add "WITH Linux-syscall-note" to SPDX tag of uapi headers
UAPI headers licensed under GPL are supposed to have exception
"WITH Linux-syscall-note" so that they can be included into non-GPL
user space application code.

The exception note is missing in some UAPI headers.

Some of them slipped in by the treewide conversion commit b24413180f
("License cleanup: add SPDX GPL-2.0 license identifier to files with
no license"). Just run:

  $ git show --oneline b24413180f -- arch/x86/include/uapi/asm/

I believe they are not intentional, and should be fixed too.

This patch was generated by the following script:

  git grep -l --not -e Linux-syscall-note --and -e SPDX-License-Identifier \
    -- :arch/*/include/uapi/asm/*.h :include/uapi/ :^*/Kbuild |
  while read file
  do
          sed -i -e '/[[:space:]]OR[[:space:]]/s/\(GPL-[^[:space:]]*\)/(\1 WITH Linux-syscall-note)/g' \
          -e '/[[:space:]]or[[:space:]]/s/\(GPL-[^[:space:]]*\)/(\1 WITH Linux-syscall-note)/g' \
          -e '/[[:space:]]OR[[:space:]]/!{/[[:space:]]or[[:space:]]/!s/\(GPL-[^[:space:]]*\)/\1 WITH Linux-syscall-note/g}' $file
  done

After this patch is applied, there are 5 UAPI headers that do not contain
"WITH Linux-syscall-note". They are kept untouched since this exception
applies only to GPL variants.

  $ git grep --not -e Linux-syscall-note --and -e SPDX-License-Identifier \

ASoC: SOF: use __u32 instead of uint32_t in uapi headers
When CONFIG_UAPI_HEADER_TEST=y, exported headers are compile-tested to
make sure they can be included from user-space.

Currently, header.h and fw.h are excluded from the test coverage.
To make them join the compile-test, we need to fix the build errors
attached below.

For a case like this, we decided to use __u{8,16,32,64} variable types
in this discussion:

  https://lkml.org/lkml/2019/6/5/18

ASoC: SOF: Add DMIC token for unmute gain ramp time
The settling time of DMIC DC level is both platform and used
microphone model specific. The unmute gain ramp is used to conceal
most of the large DC level seen in beginning of capture. This patch
adds into the DMIC DAI IPC struct a new field called unmute_ramp_time
and a new token SOF_TKN_INTEL_DMIC_UNMUTE_RAMP_TIME. The value is the
ramp length in milliseconds (ms).

The ABI minor version is incremented for this backwards compatible
change.

ASoC: SOF: bump to ABI 3.6
We had a couple of misses with ABI changes, e.g. for Xtensa oops
information and the integration of sound trigger, before we set-up a
formal process to track evolutions.

With this patch, the SOF kernel patches are officially aligned with
the firmware 3.6 level. Changing this level has no impact on existing
users and is fully backwards-compatible.

b5bdbb6ccd ALSA: uapi: #include <time.h> in asound.h
The uapi header asound.h defines types based on struct timespec. We need
to #include <time.h> to get access to the definition of this struct.

Previously, we encountered the following error message when building
applications with a clang/bionic toolchain:

kernel-headers/sound/asound.h:350:19: error: field has incomplete type 'struct timespec'
  struct timespec trigger_tstamp;
                  ^

The absence of the time.h #include statement does not cause build errors
with glibc, because its version of stdlib.h indirectly includes time.h.

a8c0d13267 ALSA: firewire-tascam: notify events of change of state for userspace applications
In former commits, ALSA firewire-tascam driver queues events to notify
change of state of control surface to userspace via ALSA hwdep
interface.

This commit implements actual notification of the events. The events are
not governed by real time, thus no need to care underrun.

d716742243 ALSA: firewire-tascam: queue events for change of control surface
Units of TASCAM FireWire series transfer image of states of the unit in
tx isochronous packets. Demultiplexing of the states from the packets
is done in software interrupt context regardless of any process context.
In a view of userspace applications, it needs to have notification
mechanism to catch change of the states.

This commit implements a queue to store events for the notification. The
image of states includes fluctuating data such as level of gain/volume
for physical input/output and position of knobs. Therefore the events
are queued corresponding to some control features only.

Furthermore, the queued events are planned to be consumed by userspace
applications via ALSA hwdep interface. This commit suppresses event
queueing when no applications open the hwdep interface.

However, the queue is maintained in an optimistic scenario, thus without
any care against overrrun. This is reasonable because target events are
useless just to handle PCM frames. It starts queueing when an usespace
application opens hwdep interface, thus it's expected to read the queued
events steadily.

90e8ac5c9d ALSA: firewire-tascam: add new hwdep ioctl command to get state image
In a previous commit, ALSA firewire-tascam driver stores state image
from tx isochronous packets. This image includes states of knob, fader,
button of control surface, level of gain/volume of each physical
inputs/outputs, and so on. It's useful for userspace applications to
read whole of the image.

This commit adds a unique ioctl command for ALSA hwdep interface for the
purpose. For actual meaning of each bits in this image, please refer to
discussion in alsa-devel[1].

08f9f4485f ALSA: core api: define offsets for TLV items
Currently, there are no pre-defined accessors for the elements
in topology TLV data. In the absence of such offsets, the
tlv data will have to be decoded using hardwired offset
numbers 0-N depending on the type of TLV. This patch defines
accessor offsets for the type, length, min and mute/step items
in TLV data for DB_SCALE type tlv's. These will be used by drivers to
decode the TLV data while loading topology thereby improving
code readability. The type and len offsets are common for all TLV
types. The min and step/mute offsets are specific to DB_SCALE tlv type.

ASoC: topology: Add missing clock gating parameter when parsing hw_configs
Clock gating parameter is a part of `dai_fmt`. It is supported by
`alsa-lib` when creating a topology binary file, but ignored by kernel
when loading this topology file.

After applying this commit, the clock gating parameter is not ignored any
more. This solution is backwards compatible. The existing behaviour is
not broken, because by default the parameter value is 0 and is ignored.

snd_soc_tplg_hw_config.clock_gated = 0 => no effect
snd_soc_tplg_hw_config.clock_gated = 1 => SND_SOC_DAIFMT_GATED
snd_soc_tplg_hw_config.clock_gated = 2 => SND_SOC_DAIFMT_CONT

For example, the following config, based on
alsa-lib/src/conf/topology/broadwell/broadwell.conf, is now supported:

~~~~
SectionHWConfig."CodecHWConfig" {
        id "1"
        format "I2S"            # physical audio format.
        pm_gate_clocks "true"   # clock can be gated
}

SectionLink."Codec" {

        # used for binding to the physical link
        id "0"

        hw_configs [
                "CodecHWConfig"
        ]

        default_hw_conf_id "1"
}

 - tools/arch/x86/lib/memcpy_64.S:

     Sync the code and add tools/include/asm/export.h with dummy wrappers
     to support building the kernel side code in a tooling header environment.

 - tools/include/uapi/asm-generic/mman.h,
   tools/include/uapi/linux/bpf.h:

e2be04c7f9 License cleanup: add SPDX license identifier to uapi header files with a license
Many user space API headers have licensing information, which is either
incomplete, badly formatted or just a shorthand for referring to the
license under which the file is supposed to be.  This makes it hard for
compliance tools to determine the correct license.

Update these files with an SPDX license identifier.  The identifier was
chosen based on the license information in the file.

GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license
identifier with the added 'WITH Linux-syscall-note' exception, which is
the officially assigned exception identifier for the kernel syscall
exception:

   NOTE! This copyright does *not* cover user programs that use kernel
   services by normal system calls - this is merely considered normal use
   of the kernel, and does *not* fall under the heading of "derived work".

This exception makes it possible to include GPL headers into non GPL
code, without confusing license compliance tools.

Headers which have either explicit dual licensing or are just licensed
under a non GPL license are updated with the corresponding SPDX
identifier and the GPLv2 with syscall exception identifier.  The format
is:
        ((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE)

SPDX license identifiers are a legally binding shorthand, which can be
used instead of the full boiler plate text.  The update does not remove
existing license information as this has to be done on a case by case
basis and the copyright holders might have to be consulted. This will
happen in a separate step.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.  See the previous patch in this series for the
methodology of how this patch was researched.

6f52b16c5b License cleanup: add SPDX license identifier to uapi header files with no license
Many user space API headers are missing licensing information, which
makes it hard for compliance tools to determine the correct license.

By default are files without license information under the default
license of the kernel, which is GPLV2.  Marking them GPLV2 would exclude
them from being included in non GPLV2 code, which is obviously not
intended. The user space API headers fall under the syscall exception
which is in the kernels COPYING file:

   NOTE! This copyright does *not* cover user programs that use kernel
   services by normal system calls - this is merely considered normal use
   of the kernel, and does *not* fall under the heading of "derived work".

otherwise syscall usage would not be possible.

Update the files which contain no license information with an SPDX
license identifier.  The chosen identifier is 'GPL-2.0 WITH
Linux-syscall-note' which is the officially assigned identifier for the
Linux syscall exception.  SPDX license identifiers are a legally binding
shorthand, which can be used instead of the full boiler plate text.

4b671f5774 ALSA: pcm: Add an ioctl to specify the supported protocol version
We have an ioctl to inform the PCM protocol version the running kernel
supports, but there is no way to know which protocol version the
user-space can understand.  This lack of information caused headaches
in the past when we tried to extend the ABI.  For example, because we
couldn't guarantee the validity of the reserved bytes, we had to
introduce a new ioctl SNDRV_PCM_IOCTL_STATUS_EXT for assigning a few
new fields in the formerly reserved bits.  If we could know that it's
a new alsa-lib, we could assume the availability of the new fields,
thus we could have reused the existing SNDRV_PCM_IOCTL_STATUS.

In order to improve the ABI extensibility, this patch adds a new ioctl
for user-space to inform its supporting protocol version to the
kernel.  By reporting the supported protocol from user-space, the
kernel can judge which feature should be provided and which not.

With the addition of the new ioctl, the PCM protocol version is bumped
to 2.0.14, too.  User-space checks the kernel protocol version via
SNDRV_PCM_INFO_PVERSION, then it sets the supported version back via
SNDRV_PCM_INFO_USER_PVERSION.

42f945970a ALSA: pcm: Add the explicit appl_ptr sync support
Currently x86 platforms use the PCM status/control mmaps for
transferring the PCM status and appl_ptr between kernel and
user-spaces.  The mmap is a most efficient way of communication, but
it has a drawback per its nature, namely, it can't notify the change
explicitly to kernel.

The lack of appl_ptr update notification is a problem on a few
existing drivers, but it's mostly a small issue and negligible.
However, a new type of driver that uses DSP for a deep buffer
management requires the exact position of appl_ptr for calculating the
buffer prefetch size, and the asynchronous appl_ptr update between
kernel and user-spaces becomes a significant problem for it.

How can we enforce user-space to report the appl_ptr update?  The way
is relatively simple.  Just by disabling the PCM control mmap, the
user-space is supposed to fall back to the mode using SYNC_PTR ioctl,
and the kernel gets control over that.  This fallback mode is used in
all non-x86 platforms as default, and also in the 32bit compatible
model on all platforms including x86.  It's been implemented already
over a decade, so we can say it's fairly safe and stably working.

With the help of the knowledge above, this patch introduces a new PCM
info flag SNDRV_PCM_INFO_SYNC_APPLPTR for achieving the appl_ptr sync
from user-space.  When a driver sets this flag at open, the PCM status
/ control mmap is disabled, which effectively switches to SYNC_PTR
mode in user-space side.

In this version, both PCM status and control mmaps are disabled
although only the latter, control mmap, is the target.  It's because
the current alsa-lib implementation supposes that both status and
control mmaps are always coupled, thus it handles a fatal error when
only one of them fails.

Of course, the disablement of the status/control mmaps may bring a
slight performance overhead.  Thus, as of now, this should be used
only for the dedicated devices that deserves.

Note that the disablement of mmap is a sort of workaround.  In the
later patch, we'll introduce the way to identify the protocol version
alsa-lib supports, and keep mmap working while the sync_ptr is
performed together.

939df3ada7 ASoC: Intel: Skylake: Add deep buffer support
With this patch, the dma buffer size is fetched from topology binary. This
buffer size is applicable for gateway copier modules.

Now that we can configure DSP dma buffer size, the device can support deep
buffer playback. DSP fetches large buffer and can result fewer wakes,
which helps in power reduction.

fcc8487d47 uapi: export all headers under uapi directories
Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

exported (with make headers_install_all):

This commit adds hwdep interface so as the other drivers for audio and
music units on IEEE 1394 have.

This interface is designed for mixer/control applications. By using this
interface, an application can get information about firewire node, can
lock/unlock kernel streaming and can get notification at starting/stopping
kernel streaming.

MOTU FireWire series can transfer messages to registered address. These
messages are transferred for the status of internal clock synchronization
just after starting streams.

When the synchronization is stable, it's 0x01ffffff. Else, it's 0x05ffffff.

This commit adds a functionality for user space applications to receive
content of the message.
