This patch adds iomapping for the region2 section of memory on the SBZ.
This memory region is used in later patches for setting inputs and
outputs. If the mapping fails, the quirk is changed back to QUIRK_NONE
to avoid attempts to write to uninitialized memory.
It also adds a new exit sequence to unmap the iomem for the SBZ.

This patch adds an unsolicited response tag for the front headphone
panel which uses the same hp_callback as the rear headphone detection.
This patch also adds pincfgs for the R3Di and SBZ which were taken from
the Windows driver. The pins are also defined in the function
ca0132_config. Both the R3Di and SBZ are also given a max out channel
value of 6 to handle 5.1 surround sound in later patches.

This patch adds PCI quirk ID's for the Sound Blaster Z and Recon3Di.
Only the currently tested ID's have been added.
This patch also adds the ability to load alternative firmwares for each
card, the firmwares can be obtained from within the Windows driver.
The Recon3Di uses "ctefx-r3di.bin" and the Sound Blaster Z uses
"ctefx-sbz.bin". If the alternative firmware for the given quirk is not
found, the original ctefx.bin will be used. This has been confirmed to
work for both the R3Di and the SBZ.
This patch also makes the character array *dirstr a const.

The DP-MST support requires more PCM streams than usual, hence
CONFIG_SND_DYNAMIC_MINORS is almost mandatory. Currently the driver
just warns and continues even if streams are missing, but it doesn't
seem to enough convince users to switch to the modern setup.
This patch adds the enforced selection of CONFIG_SND_DYNAMIC_MINORS
from CONFIG_SND_HDA_CODEC_HDMI for covering that.

When CONFIG_SND_DYNAMIC_MINORS isn't set, there are only limited
number of devices available, and HD-audio, especially with HDMI/DP
codec, will fail to create more than two devices.
The driver warns about the lack of such devices and skips the PCM
device creations, but the HDMI driver still tries to create the
corresponding JACK, SPDIF and ELD controls even for the non-existing
PCM substreams. This results in confusion on user-space, and even may
break the operation.
Similarly, Intel HDMI/DP codec builds the ELD notification from i915
graphics driver, and this may be broken if a notification is sent for
the non-existing PCM stream.
This patch adds the check of the existence of the assigned PCM
substream in the both scenarios above, and skips the further operation
if the PCM substream is not assigned.

The emu10k1 fx8010 code allocates each irq resource dynamically and
links to the list at PCM trigger callback. Due to the nature of
trigger callback, the allocation is done with GFP_ATOMIC, hence it
may fail more often. Moreover, the irq resource isn't big at all, and
using the kmalloc for this won't save many bytes, either.
This patch removes the dynamic allocation and embeds the irq resource
into struct snd_emu10k1_fx8010_pcm.irq field instead of keeping a
pointer. As a result, it simplifies the code and removes the
unnecessary GFP_ATOMIC usage.

The system sleep PM ops azx_suspend() and azx_resume() were previously
called by vga_switcheroo, but commit 07f4f97d7b ("vga_switcheroo: Use
device link for HDA controller") removed their invocation.
Unfortunately the commit neglected to update the #ifdef surrounding the
two functions, so if CONFIG_PM_SLEEP is *not* enabled but all three of
CONFIG_PM, CONFIG_VGA_SWITCHEROO and CONFIG_SND_HDA_CODEC_HDMI *are*
enabled, the compiler now emits the following warning:
sound/pci/hda/hda_intel.c:1024:12: warning: 'azx_resume' defined but not used [-Wunused-function]

^~~~~~~~~~
sound/pci/hda/hda_intel.c:989:12: warning: 'azx_suspend' defined but not used [-Wunused-function]

Silence by updating the #ifdef. Because the #ifdef block now uses the
same condition as the one immediately succeeding it, the two blocks can
be collapsed together, shaving off another two lines.

We've observed too long probe time with Coffee Lake (CFL) machines,
and the likely cause is some communication problem between the
HD-audio controller and the codec chips. While the controller expects
an IRQ wakeup for each codec response, it seems sometimes missing, and
it takes one second for the controller driver to time out and read the
response in the polling mode.
Although we aren't sure about the real culprit yet, in this patch, we
put a workaround by forcing the polling mode as default for CFL
machines; the polling mode itself isn't too heavy, and much better
than other workarounds initially suggested (e.g. disabling
power-save), at least.

Some HP laptops have a mute mute LED controlled by a pin VREF. The
Realtek codec driver updates the VREF via vmaster hook by calling
snd_hda_set_pin_ctl_cache().
This works fine as long as the driver is running in a normal mode.
However, when the VREF change happens during the codec being in
runtime PM suspend, the regmap access will skip and postpone the
actual register change. This ends up with the unchanged LED status
until the next runtime PM resume even if you change the Master mute
switch. (Interestingly, the machine keeps the LED status even after
the codec goes into D3 -- but it's another story.)
For improving this usability, let the driver temporarily powering up /
down only during the pin VREF change. This can be achieved easily by
wrapping the call with snd_hda_power_up_pm() / *_down_pm().

Back in 2013, runtime PM for GPUs with integrated HDA controller was
introduced with commits 0d69704ae3 ("gpu/vga_switcheroo: add driver
control power feature. (v3)") and 246efa4a07 ("snd/hda: add runtime
suspend/resume on optimus support (v4)").
Briefly, the idea was that the HDA controller is forced on and off in
unison with the GPU.
The original code is mostly still in place even though it was never a
100% perfect solution: E.g. on access to the HDA controller, the GPU
is powered up via vga_switcheroo_runtime_resume_hdmi_audio() but there
are no provisions to keep it resumed until access to the HDA controller
has ceased: The GPU autosuspends after 5 seconds, rendering the HDA
controller inaccessible.
Additionally, a kludge is required when hda_intel.c probes: It has to
check whether the GPU is powered down (check_hdmi_disabled()) and defer
probing if so.
However in the meantime (in v4.10) the driver core has gained a feature
called device links which promises to solve such issues in a clean way:
It allows us to declare a dependency from the HDA controller (consumer)
to the GPU (supplier). The PM core then automagically ensures that the
GPU is runtime resumed as long as the HDA controller's ->probe hook is
executed and whenever the HDA controller is accessed.
By default, the HDA controller has a dependency on its parent, a PCIe
Root Port. Adding a device link creates another dependency on its
sibling:
PCIe Root Port
^ ^
| |
| |
HDA ===> GPU
The device link is not only used for runtime PM, it also guarantees that
on system sleep, the HDA controller suspends before the GPU and resumes
after the GPU, and on system shutdown the HDA controller's ->shutdown
hook is executed before the one of the GPU. It is a complete solution.
Using this functionality is as simple as calling device_link_add(),
which results in a dmesg entry like this:
pci 0000:01:00.1: Linked as a consumer to 0000:01:00.0
The code for the GPU-governed audio power management can thus be removed
(except where it's still needed for legacy manual power control).
The device link is added in a PCI quirk rather than in hda_intel.c.
It is therefore legal for the GPU to runtime suspend to D3cold even if
the HDA controller is not bound to a driver or if CONFIG_SND_HDA_INTEL
is not enabled, for accesses to the HDA controller will cause the GPU to
wake up regardless if they're occurring outside of hda_intel.c (think
config space readout via sysfs).
Contrary to the previous implementation, the HDA controller's power
state is now self-governed, rather than GPU-governed, whereas the GPU's
power state is no longer fully self-governed. (The HDA controller needs
to runtime suspend before the GPU can.)
It is thus crucial that runtime PM is always activated on the HDA
controller even if CONFIG_SND_HDA_POWER_SAVE_DEFAULT is set to 0 (which
is the default), lest the GPU stays awake. This is achieved by setting
the auto_runtime_pm flag on every codec and the AZX_DCAPS_PM_RUNTIME
flag on the HDA controller.
A side effect is that power consumption might be reduced if the GPU is
in use but the HDA controller is not, because the HDA controller is now
allowed to go to D3hot. Before, it was forced to stay in D0 as long as
the GPU was in use. (There is no reduction in power consumption on my
Nvidia GK107, but there might be on other chips.)
The code paths for legacy manual power control are adjusted such that
runtime PM is disabled during power off, thereby preventing the PM core
from resuming the HDA controller.
Note that the device link is not only added on vga_switcheroo capable
systems, but for *any* GPU with integrated HDA controller. The idea is
that the HDA controller streams audio via connectors located on the GPU,
so the GPU needs to be on for the HDA controller to do anything useful.
This commit implicitly fixes an unbalanced runtime PM ref upon unbind of
hda_intel.c: On ->probe, a runtime PM ref was previously released under
the condition "azx_has_pm_runtime(chip) || hda->use_vga_switcheroo", but
on ->remove a runtime PM ref was only acquired under the first of those
conditions. Thus, binding and unbinding the driver twice on a
vga_switcheroo capable system caused the runtime PM refcount to drop
below zero. The issue is resolved because the AZX_DCAPS_PM_RUNTIME flag
is now always set if use_vga_switcheroo is true.

With the commit 1ba8f9d308 ("ALSA: hda: Add a power_save
blacklist"), we changed the default value of power_save option to -1
for processing the power-save blacklist.
Unfortunately, this seems breaking user-space applications that
actually read the power_save parameter value via sysfs and judge /
adjust the power-saving status. They see the value -1 as if the
power-save is turned off, although the actual value is taken from
CONFIG_SND_HDA_POWER_SAVE_DEFAULT and it can be a positive.
So, overall, passing -1 there was no good idea. Let's partially
revert it -- at least for power_save option default value is restored
again to CONFIG_SND_HDA_POWER_SAVE_DEFAULT. Meanwhile, in this patch,
we keep the blacklist behavior and make is adjustable via the new
option, pm_blacklist.

On some boards setting power_save to a non 0 value leads to clicking /
popping sounds when ever we enter/leave powersaving mode. Ideally we would
figure out how to avoid these sounds, but that is not always feasible.
This commit adds a blacklist for devices where powersaving is known to
cause problems and disables it on these devices.
Note I tried to put this blacklist in userspace first:
https://github.com/systemd/systemd/pull/8128
But the systemd maintainers rightfully pointed out that it would be
impossible to then later remove entries once we actually find a way to
make power-saving work on listed boards without issues. Having this list
in the kernel will allow removal of the blacklist entry in the same commit
which fixes the clicks / plops.
The blacklist only applies to the default power_save module-option value,
if a user explicitly sets the module-option then the blacklist is not
used.

The Audigy 2 CA0102 chip (but most likely others from the emu10k1 family,
too) has a problem that from time to time it likes to do few DMA reads a
bit beyond its normal allocation and gets very confused if these reads get
blocked by a IOMMU.
For the first (reserved) page this happens multiple times at every
playback, for various synth pages it happens randomly, rarely for PCM
playback buffers and the page table memory itself.
All these reads seem to follow a similar pattern, observed read offsets
beyond the allocation end were 0x00, 0x40, 0x80 and 0xc0 (PCI cache line
multiples), so it looks like the device tries to accesses up to 256 extra
bytes.
As a workaround let's widen these DMA allocations by an extra page if we
detect that the device is behind a non-passthrough IOMMU (the DMA memory
should be relatively plenty on IOMMU systems).

Commit a5003fc041 ("[ALSA] emu10k1 - simplify page allocation for synth")
switched from using the DMA allocator for synth DMA pages to manually

However, this usage has an implicit assumption that the DMA address space
for the emu10k1-family chip is the same as the CPU physical address space
which is not true for a system with a IOMMU.
Since this made the synth part of the driver non-functional on such systems
let's effectively revert that commit (while keeping the

The emu10k1-family chips need the first page (index 0) reserved in their
page tables for some reason (every emu10k1 driver I've checked does this
without much of an explanation).
Using the first page for normal samples results in a broken playback.
However, we already have a dummy page allocated - so called "silent page"
and, in fact, had always been setting it as the first page in the chip page
table because an initialization of every entry of the page table to point
to a silent page happens after and overwrites the reserved_page allocation.
So the only thing remaining to remove the reserved_page allocation is a
trivial change to the page allocation logic to ignore the first page entry
and start its allocations from the second entry (index 1).

pins expect to be connected with NID 0x03 while keeping the speaker
with NID 0x02. However, by adding a new line-out pin, the
auto-parser assigns the NID 0x02 for HP/LO pins as primary outputs.
As an easy workaround, we provide the preferred_pairs[] to map
forcibly for these pins. -- tiwai ]

The function "release_firmware" is called in the current implementation of
the function "_request_firmware" after a failure was detected.
Link: https://elixir.free-electrons.com/linux/v4.14-rc8/source/drivers/base/firmware_class.c#L1196

The previous fix for addressing the breakage in vmaster slave
initialization, commit a91d66129f ("ALSA: hda - Fix incorrect TLV
callback check introduced during set_fs() removal"), introduced a new
helper to process over each slave kctl. However, this helper passes
only the original kctl, not the virtual slave kctl. As a result,
HD-audio driver (which is the only user so far) couldn't initialize
the slave correctly because it's trying to update the value directly
with the original kctl, not with the mapped kctl.
This patch fixes the situation again by passing both the mapped slaved
and original slave kctls to the function. Luckily there is a single
caller as of now, so changing the call signature is no big matter.

The biggest thing this release has been the conversion of the AC98 bus
to the driver model, that's been a long time coming so thanks to Robert
Jarzmik for his dedication there. Due to there being some AC97 MFD
there's a few fairly large changes in input and the MFD layer, mainly to
the wm97xx driver.
There's also some drivers/drm changes to support the new AMD Stoney
platform, these are shared with the DRM subsystem and should be being
merged via both.
Within the subsystem the overwhelming bulk of the changes is in the
Intel drivers which continue to need lots of cleanups and fixes, this
release they've also gained support for their open source firmware.
There's also some large changs in the core as Morimoto-san continues to
mirror operations into the component level in preparation for conversion
of drivers to that.
- The AC97 bus has finally caught up with the driver model thanks to
some dedicated and persistent work from Robert Jarzmik.
- Continued work from Morimoto-san on moving us towards being able to
use components for everything.
- Lots of cleanups for the Intel platform code, including support for
their open source audio firmware.
- Support for scaling MCLK with sample rate in simple-card.
- Support for AMD Stoney platform.

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

The refresh of HD-audio widget sysfs kobjects via
snd_hdac_refresh_widget_sysfs() is slightly racy.
The driver recreates the whole tree from scratch after deleting the
whole. When CONFIG_DEBUG_KOBJECT_RELEASE option is used, kobject
release doesn't happen immediately but delayed, while the re-creation
of the same named kobject happens soon after invoking kobject_put().
This may end up with the conflicts of duplicated kobjects, as found in
the bug report below.
In this patch, we take another approach to refresh the tree: instead
of recreating the whole tree, just add the new nodes and delete the
non-existing nodes. Since the refresh happens only once at
initialization, no longer race would happen.
Along with the code change, merge snd_hdac_refresh_widget_sysfs() with
the existing snd_hdac_refresh_widgets() with an additional bool flag
for simplifying the code.

For allowing user to apply the existing quirk on a machine with a
different SSID, add a new model string entry, alc700-ref.

Signed-off-by: Takashi Iwai <tiwai@suse.de>
The commit 99b5c5bb9a ("ALSA: hda - Remove the use of set_fs()")
converted the get_kctl_0dB_offset() call for killing set_fs() usage in
HD-audio codec code. The conversion assumed that the TLV callback
used in HD-audio code is only snd_hda_mixer_amp() and applies the TLV
calculation locally.
Although this assumption is correct, and all slave kctls are actually
with that callback, the current code is still utterly buggy; it
doesn't hit this condition and falls back to the next check. It's
because the function gets called after adding slave kctls to vmaster.
By assigning a slave kctl, the slave kctl object is faked inside
vmaster code, and the whole kctl ops are overridden. Thus the
callback op points to a different value from what we've assumed.
More badly, as reported by the KERNEXEC and UDEREF features of PaX,
the code flow turns into the unexpected pitfall. The next fallback
check is SNDRV_CTL_ELEM_ACCESS_TLV_READ access bit, and this always
hits for each kctl with TLV. Then it evaluates the callback function
pointer wrongly as if it were a TLV array. Although currently its
side-effect is fairly limited, this incorrect reference may lead to an
unpleasant result.
For addressing the regression, this patch introduces a new helper to
vmaster code, snd_ctl_apply_vmaster_slaves(). This works similarly
like the existing map_slaves() in hda_codec.c: it loops over the slave
list of the given master, and applies the given function to each
slave. Then the initializer function receives the right kctl object
and we can compare the correct pointer instead of the faked one.
Also, for catching the similar breakage in future, give an error
message when the unexpected TLV callback is found and bail out
immediately.

This reverts commit 275353bb68 to fix a regression which can abort

alsactl: control.c:2976: snd_ctl_elem_value_get_integer: Assertion `idx < ARRAY_SIZE(obj->value.integer.value)' failed.
This commit is a band-aid. In a point of usage of ALSA control interface,
the drivers still bring an issue that they prevent userspace applications
to have a consistent way to parse each levels of the dimension information
via ALSA control interface.
Let me investigate this issue. Current implementation of the drivers
have three control element sets with dimension information:
* 'Monitor Mixer Volume' (type: integer)
* 'VMixer Volume' (type: integer)
* 'VU-meters' (type: boolean)
Although the number of elements named as 'Monitor Mixer Volume' differs
depending on drivers in this group, it can be calculated by macros
defined by each driver (= (BX_NUM - BX_ANALOG_IN) * BX_ANALOG_IN). Each
of the elements has one member for value and has dimension information
with 2 levels (= BX_ANALOG_IN * (BX_NUM - BX_ANALOG_IN)). For these
elements, userspace applications are expected to handle the dimension
information so that all of the elements construct a matrix where the
number of rows and columns are represented by the dimension information.
The same way is applied to elements named as 'VMixer Volume'. The number
of these elements can also be calculated by macros defined by each
drivers (= PX_ANALOG_IN * BX_ANALOG_IN). Each of the element has one
member for value and has dimension information with 2 levels
(= BX_ANALOG_IN * PX_ANALOG_IN). All of the elements construct a matrix
with the dimension information.
An element named as 'VU-meters' gets a different way in a point of
dimension information. The element includes 96 members for value. The
element has dimension information with 3 levels (= 3 or 2 * 16 * 2). For
this element, userspace applications are expected to handle the dimension
information so that all of the members for value construct a matrix
where the number of rows and columns are represented by the dimension
information. This is different from the way for the former.
As a summary, the drivers were not designed to produce a consistent way to
parse the dimension information. This makes it hard for general userspace
applications such as amixer to parse the information by a consistent way,
and actually no userspace applications except for 'echomixer' utilize the
dimension information. Additionally, no drivers excluding this group use
the information.
The reverted commit was written based on the latter way. A commit
860c1994a7 ('ALSA: control: add dimension validator for userspace
elements') is written based on the latter way, too. The patch should be
reconsider too in the same time to re-define a consistent way to parse the
dimension information.

On recent Intel platforms (Haswell, Broadwell, Skylake, ApolloLake,
KabyLake, ...), the IEC Coding Type (ICT) bitfield in the Digital
Converter Control #3 needs to be set explicitly for HDMI/DisplayPort
High Bit Rate (HBR) audio playback to work. This was not required in
earlier platforms when HBR was first introduced. The ICT bits are
defined in Section 7.3.3.9 of the HDaudio 1.0a specification.
Since the ICT bitfield was not specified for HDAudio 1.0 devices
(before 2009), we only program it on machines more recent than
Haswell.
We tested that this fix is not needed on Baytrail-I (MinnowBoard
Turbot) and believe by extension it also does not apply to Braswell.

The hm->h.size is intended to hold the actual size of the hm struct
that is copied from userspace and should always be <= sizeof(*hm).
However, after copy_from_user(hm, puhm, hm->h.size), since userspace
process has full control over the memory region pointed by puhm, it is
possible that the value of hm->h.size is different from what is fetched-in
previously (get_user(hm->h.size, (u16 __user *)puhm)). In other words,
hm->h.size is overriden and the relation between hm->h.size and the hm
struct is broken.
This patch proposes to use a seperate variable, msg_size, to hold
the value of the first fetch and override hm->h.size to msg_size
after the second fetch to maintain the relation.

Dell laptops have another LED for mic-mute in addition to the master
mute. The former is tied with the capture switch (in a reverse way)
while the latter is tied with the master playback switch. We already
have an enum control to change the behavior for the master mute LED in
different ways, e.g. keeping always off or turning off at mute. But,
the mic-mute LED has no such management but its behavior is
hard-coded.
This patch implements an enum control to change the mic-mute LED
behavior like what we have for the master mute LED. The ctl provides
four modes: keep-on, keep-off, follow-capture and follow-mute. The
default mode is the last one, follow-mute, which follows the capture
mute, i.e. LED turning on when the capture is off, and turning off
when the capture is active.

sound/pci/pcxhr/pcxhr.c:1647:28: error: ' [PCM #' directive writing 7 bytes into a region of size between 1 and 32 [-Werror=format-overflow=]
The shortname can simply be removed, and the longname can
be changed into a shorter "name" string that is used in three
places. Making it a little shorter (40 bytes) avoids the risk of
overflowing completely, but I also use snprintf() here for
extra clarity.

The commit b56fa687e0 ("ALSA: fm801: detect FM-only card earlier")
rearranged initialization calls, i.e. it makes snd_fm801_chip_init() to
be called before we register interrupt handler and set PCI bus
mastering.
Somehow it prevents FM801-AU to work properly. Thus, partially revert
initialization order changed by commit mentioned above.

This development cycle resulted in a fair amount of changes in both
core and driver sides. The most significant change in ALSA core is
about PCM. Also the support of of-graph card and the new DAPM widget
for DSP are noteworthy changes in ASoC core. And there're lots of
small changes splat over the tree, as you can see in diffstat.
Below are a few highlights:
ALSA core:
- Removal of set_fs() hackery from PCM core stuff, and the code
reorganization / optimization thereafter
- Improved support of PCM ack ops, and a new ABI for improved
control/status mmap handling
- Lots of constifications in various codes
ASoC core:
- The support of of-graph card, which may work as a better generic
device for a replacement of simple-card
- New widget types intended mainly for use with DSPs
ASoC drivers:
- New drivers for Allwinner V3s SoCs
- Ensonic ES8316 codec support
- More Intel SKL and KBL works
- More device support for Intel SST Atom (mostly for cheap tablets and
2-in-1 devices)
- Support for Rockchip PDM controllers
- Support for STM32 I2S and S/PDIF controllers
- Support for ZTE AUD96P22 codecs
HD-audio:
- Support of new Realtek codecs (ALC215/ALC285/ALC289), more quirks
for HP and Dell machines
- A few more fixes for i915 component binding
Note that of-graph change may bring the conflicts with a later pull
request of devicetree, as currently found in linux-next.

Pull scheduler updates from Ingo Molnar:
"The main changes in this cycle were:
- Add the SYSTEM_SCHEDULING bootup state to move various scheduler
debug checks earlier into the bootup. This turns silent and
sporadically deadly bugs into nice, deterministic splats. Fix some
of the splats that triggered. (Thomas Gleixner)
- A round of restructuring and refactoring of the load-balancing and
topology code (Peter Zijlstra)
- Another round of consolidating ~20 of incremental scheduler code
history: this time in terms of wait-queue nomenclature. (I didn't
get much feedback on these renaming patches, and we can still
easily change any names I might have misplaced, so if anyone hates
a new name, please holler and I'll fix it.) (Ingo Molnar)
- sched/numa improvements, fixes and updates (Rik van Riel)
- Another round of x86/tsc scheduler clock code improvements, in hope
of making it more robust (Peter Zijlstra)
- Improve NOHZ behavior (Frederic Weisbecker)
- Deadline scheduler improvements and fixes (Luca Abeni, Daniel
Bristot de Oliveira)
- Simplify and optimize the topology setup code (Lauro Ramos
Venancio)
- Debloat and decouple scheduler code some more (Nicolas Pitre)
- Simplify code by making better use of llist primitives (Byungchul
Park)
- ... plus other fixes and improvements"

In the commit fcc88d91cd ("ALSA: hda - Bind with i915 component
before codec binding"), the binding with i915 audio component is moved
to be performed always at probing the controller. This fixed the
potential problems on IVB, but now it brought another issue on HSW and
BDW. These two platforms give two individual HD-audio controllers,
one for the analog codec on PCH and another for HDMI over gfx. Since
I decided to take a lazy path to check only AZX_DRIVER_PCH type in the
commit above, now both controllers try to bind with i915, and you see
a kernel WARNING.
This patch tries to address it again properly. Now a new DCAPS bit,
AZX_DCAPS_I915_COMPONENT, is introduced for indicating the binding
with i915 component in addition to the existing I915_POWERWELL bit
flag. Each PCI entry has to give this new flag if it requires the
binding with i915 component. For HSW/BDW PCH (i.e. the ones defined
by AZX_DCAPS_INTEL_PCH) doesn't contain AZX_DCAPS_I915_COMPONENT bit
while others have it.
While we're at it, add parentheses around the bit flag check for
avoiding possible compiler warnings, too.
The bug was spotted by Intel CI tests.

We used a on-demand i915 component binding for IvyBridge and
SandyBridge HDMI codecs, but it has a potential problem of the nested
module loading. For avoiding that situation, assure the i915 binding
happening at the controller driver level for PCH controller devices,
where the initialization is performed in a detached work, instead of
calling from the codec driver probe.

It's nonsense to register a card object when no codec is bound on it,
as we don't support the deferred codec binding. Instead of
registering an empty card object, just skip the registration by
returning an error from azx_codec_configure().
Signed-off-by: Takashi Iwai <tiwai@suse.de>
azx_codec_configure() loops over the codecs found on the given
controller via a linked list. The code used to work in the past, but
in the current version, this may lead to an endless loop when a codec
binding returns an error.
The culprit is that the snd_hda_codec_configure() unregisters the
device upon error, and this eventually deletes the given codec object
from the bus. Since the list is initialized via list_del_init(), the
next object points to the same device itself. This behavior change
was introduced at splitting the HD-audio code code, and forgotten to
adapt it here.
For fixing this bug, just use a *_safe() version of list iteration.

Recently we met a problem, the codec has valid adcs and input pins,
and they can form valid input paths, but the driver does not build
valid controls for them like "Mic boost", "Capture Volume" and
"Capture Switch".
Through debugging, I found the driver needs to shrink the invalid
adcs and input paths for this machine, so it will move the whole
column bitmap value to the previous column, after moving it, the
driver forgets to set the original column bitmap value to zero, as a
result, the driver will invalidate the path whose index value is the
original colume bitmap value. After executing this function, all
valid input paths are invalidated by a mistake, there are no any
valid input paths, so the driver won't build controls for them.

Rename:
wait_queue_t => wait_queue_entry_t
'wait_queue_t' was always a slight misnomer: its name implies that it's a "queue",
but in reality it's a queue *entry*. The 'real' queue is the wait queue head,
which had to carry the name.
Start sorting this out by renaming it to 'wait_queue_entry_t'.
This also allows the real structure name 'struct __wait_queue' to
lose its double underscore and become 'struct wait_queue_entry',
which is the more canonical nomenclature for such data types.

We checked the quirks specific to the recent Intel chips by checking
the PCI IDs manually, but it's becoming messy with lots of IS_SKL()
and other macros, as the amount accumulated.
For simplification, here the new AZX_DRIVER_SKL type is introduced,
and check chip->driver_type instead of the manual PCI ID. The short
name for this is still "HDA Intel PCH", so that it doesn't break the
existing user-space unnecessarily.

Many drivers bind the sequencer stuff in off-load by another driver
module, so that it's loaded only on demand. In the current code, this
mechanism doesn't work when the driver is built-in while the sequencer
is module. We check with IS_REACHABLE() and enable only when the
sequencer is in the same level of build.
However, this is basically a overshoot. The binder code
(snd-seq-device) is an individual module from the sequencer core
(snd-seq), and we just have to make the former a built-in while
keeping the latter a module for allowing the scenario like the above.
This patch achieves that by rewriting Kconfig slightly. Now, a driver
that provides the manual sequencer device binding should select
CONFIG_SND_SEQ_DEVICE in a way as
select SND_SEQ_DEVICE if SND_SEQUENCER != n
Note that the "!=n" is needed here to avoid the influence of the
sequencer core is module while the driver is built-in.
Also, since rawmidi.o may be linked with snd_seq_device.o when
built-in, we have to shuffle the code to make the linker happy.
(the kernel linker isn't smart enough yet to handle such a case.)
That is, snd_seq_device.c is moved to sound/core from sound/core/seq,
as well as Makefile.
Last but not least, the patch replaces the code using IS_REACHABLE()
with IS_ENABLED(), since now the condition meets always when enabled.

Instead of the non-standard way to enable the build of snd-emux-synth
module inside Makefile, rewrite Kconfig to select the item explicitly
from each driver (sbawe and emu10k1). This is the standard way.
Signed-off-by: Takashi Iwai <tiwai@suse.de>
This is a slightly intensive rewrite of Kconfig and Makefile about
ALSA sequencer stuff.
The first major change is that the kconfig items for the sequencer are
moved to sound/core/seq/Kconfig. OK, that's easy.
The substantial change is that, instead of hackish top-level module
selection in Makefile, we define a Kconfig item for each sequencer
module. The driver that requires such sequencer components select
exclusively the kconfig items. This is more straightforward and
standard way.
