Takashi Iwai 17daae7ac4 ALSA: hda: Replace sprintf() with sysfs_emit()
For sysfs outputs, it's safer to use a new helper, sysfs_emit(),
instead of the raw sprintf() & co.  This patch replaces those usages
straightforwardly with new helpers, sysfs_emit() and sysfs_emit_at().

Steven Rostedt (Google) c71531007e tracing: ALSA: hda: Remove string manipulation out of the fast path
The TRACE_EVENT() macro is broken up into various parts to be efficient.
The TP_fast_assign() is just to record the event into the ring buffer, and
is to be done as fast as possible as this occurs during the actual running
of the code. The slower this is, the slower the code that is being traced
becomes.

The TP_printk() is processed when reading the tracing buffer. This is
considered the slow path. Any processing that can be moved from the
TP_fast_assign() to the TP_printk() should do so.

For some reason, the entire string processing of the trace events
hda_send_cmd, hda_get_response, and hda_unsol_event was moved from the
TP_printk() into the TP_fast_assign(). On top of that, the
__dynamic_array() was used with a fixed size of HDAC_MSG_MAX, which is
useless as a dynamic_array as it will always allocate HDAC_MSG_MAX bytes
on the ring buffer and even save that amount into the event (as it expects
the size to be dynamic, which using a fixed size defeats that purpose).

Instead, just save the necessary elements in the TP_fast_assign() and do
the string manipulation in the slow path.

The output should be the same.

Takashi Iwai 36a38c53b4 ALSA: hda: Fix discovery of i915 graphics PCI device
It's been reported that the recent fix for skipping the
component-binding with D-GPU caused a regression on some systems; it
resulted in the completely missing component binding with i915 GPU.

The problem was the use of pci_get_class() function.  It matches with
the full PCI class bits, while we want to match only partially the PCI
base class bits.  So, when a system has an i915 graphics device with
the PCI class 0380, it won't hit because we're looking for only the
PCI class 0300.

This patch fixes i915_gfx_present() to look up each PCI device and
match with PCI base class explicitly instead of pci_get_class().

Kai Vehmanen c9db8a30d9 ALSA: hda/i915 - skip acomp init if no matching display
In systems with only a discrete i915 GPU, the acomp init will
always timeout for the PCH HDA controller instance.

Avoid the timeout by checking the PCI device hierarchy
whether any display class PCI device can be found on the system,
and at the same level as the HDA PCI device. If found, proceed
with the acomp init, which will wait until i915 probe is complete
and component binding can proceed. If no matching display
device is found, the audio component bind can be safely skipped.

The bind timeout will still be hit if the display is present
in the system, but i915 driver does not bind to it by configuration
choice or probe error. In this case the 60sec timeout will be
hit.

ALSA: intel-nhlt: add helper to detect SSP link mask
The NHLT information can be used to figure out which SSPs are enabled
in a platform.

The 'SSP' link type is too broad for machine drivers, since it can
cover the Bluetooth sideband and the analog audio codec connections,
so this helper exposes a parameter to filter with the device
type (DEVICE_I2S refers to analog audio codec in NHLT parlance).

The helper returns a mask, since more than one SSP may be used for
analog audio, e.g. the NHLT spec describes the use of SSP0 for
amplifiers and SSP1 for headset codec. Note that if more than one bit
is set, it's impossible to determine which SSP is connected to what
external component. Additional platform-specific information based on
e.g. DMI quirks would still be required in the machine driver to
configure the relevant dailinks.

Pierre-Louis Bossart 0f7e5ee62f ALSA: HDA: hdac_ext_stream: use consistent prefixes for variables
The existing code maximizes confusion by using 'stream' and 'hstream'
variables of different types. Examples:

struct hdac_stream *stream;
struct hdac_ext_stream *stream;
struct hdac_stream *hstream;
struct hdac_ext_stream *hstream;

with some additional copy/paste remains:
struct hdac_ext_stream *azx_dev;

This patch suggests a consistent naming across all 'hdac_ext_stream'
functions. The convention is:

struct hdac_stream *hstream;
struct hdac_ext_stream *hext_stream;

No functionality change - just renaming of variables and more
consistent indentation.

Thomas Gleixner 6dd21ad81b ALSA: hda: Make proper use of timecounter
HDA uses a timecounter to read a hardware clock running at 24 MHz. The
conversion factor is set with a mult value of 125 and a shift value of 0,
which is not converting the hardware clock to nanoseconds, it is converting
to 1/3 nanoseconds because the conversion factor from 24Mhz to nanoseconds
is 125/3. The usage sites divide the "nanoseconds" value returned by
timecounter_read() by 3 to get a real nanoseconds value.

There is a lengthy comment in azx_timecounter_init() explaining this
choice. That comment makes blatantly wrong assumptions about how
timecounters work and what can overflow.

The comment says:

     * Applying the 1/3 factor as part of the multiplication
     * requires at least 20 bits for a decent precision, however
     * overflows occur after about 4 hours or less, not a option.

timecounters operate on time deltas between two readouts of a clock and use
the mult/shift pair to calculate a precise nanoseconds value:

    delta_nsec = (delta_clock * mult) >> shift;

The fractional part is also taken into account and preserved to prevent
accumulated rounding errors. For details see cyclecounter_cyc2ns().

The mult/shift pair has to be chosen so that the multiplication of the
maximum expected delta value does not result in a 64bit overflow. As the
counter wraps around on 32bit, the maximum observable delta between two
reads is (1 << 32) - 1 which is about 178.9 seconds.

That in turn means the maximum multiplication factor which fits into an u32
will not cause a 64bit overflow ever because it's guaranteed that:

     ((1 << 32) - 1) ^ 2 < (1 << 64)

The resulting correct multiplication factor is 2796202667 and the shift
value is 26, i.e. 26 bit precision. The overflow of the multiplication
would happen exactly at a clock readout delta of 6597069765 which is way
after the wrap around of the hardware clock at around 274.8 seconds which
is off from the claimed 4 hours by more than an order of magnitude.

If the counter ever wraps around the last read value then the calculation
is off by the number of wrap arounds times 178.9 seconds because the
overflow cannot be observed.

Use clocks_calc_mult_shift(), which calculates the most accurate mult/shift
pair based on the given clock frequency, and remove the bogus comment along
with the divisions at the readout sites.

Kai Vehmanen b37a15188e ALSA: hda: avoid write to STATESTS if controller is in reset
The snd_hdac_bus_reset_link() contains logic to clear STATESTS register
before performing controller reset. This code dates back to an old
bugfix in commit e8a7f136f5 ("[ALSA] hda-intel - Improve HD-audio
codec probing robustness"). Originally the code was added to
azx_reset().

The code was moved around in commit a41d122449 ("ALSA: hda - Embed bus
into controller object") and ended up to snd_hdac_bus_reset_link() and
called primarily via snd_hdac_bus_init_chip().

The logic to clear STATESTS is correct when snd_hdac_bus_init_chip() is
called when controller is not in reset. In this case, STATESTS can be
cleared. This can be useful e.g. when forcing a controller reset to retry
codec probe. A normal non-power-on reset will not clear the bits.

However, this old logic is problematic when controller is already in
reset. The HDA specification states that controller must be taken out of
reset before writing to registers other than GCTL.CRST (1.0a spec,
3.3.7). The write to STATESTS in snd_hdac_bus_reset_link() will be lost
if the controller is already in reset per the HDA specification mentioned.

This has been harmless on older hardware. On newer generation of Intel
PCIe based HDA controllers, if configured to report issues, this write
will emit an unsupported request error. If ACPI Platform Error Interface
(APEI) is enabled in kernel, this will end up to kernel log.

Fix the code in snd_hdac_bus_reset_link() to only clear the STATESTS if
the function is called when controller is not in reset. Otherwise
clearing the bits is not possible and should be skipped.

Takashi Iwai 5b1ed7df01 ALSA: control - add generic LED API
This patchset tries to resolve the diversity in the audio LED
 control among the ALSA drivers. A new control layer registration
 is introduced which allows to run additional operations on
 top of the elementary ALSA sound controls.
 
 A new control access group (three bits in the access flags)
 was introduced to carry the LED group information for
 the sound controls. The low-level sound drivers can just
 mark those controls using this access group. This information
 is not exported to the user space, but user space can
 manage the LED sound control associations through sysfs
 (last patch) per Mark's request. It makes things fully
 configurable in the kernel and user space (UCM).
 
 The actual state ('route') evaluation is really easy
 (the minimal value check for all channels / controls / cards).
 If there's more complicated logic for a given hardware,
 the card driver may eventually export a new read-only
 sound control for the LED group and do the logic itself.
 
 The new LED trigger control code is completely separated
 and possibly optional (there's no symbol dependency).
 The full code separation allows eventually to move this
 LED trigger control to the user space in future.
 Actually it replaces the already present functionality
 in the kernel space (HDA drivers) and allows a quick adoption
 for the recent hardware (ASoC codecs including SoundWire).
 
 snd_ctl_led            24576  0
 
 The sound driver implementation is really easy:
 
 1) call snd_ctl_led_request() when control LED layer should be
    automatically activated
    / it calls module_request("snd-ctl-led") on demand /
 2) mark all related kcontrols with
         SNDRV_CTL_ELEM_ACCESS_SPK_LED or
         SNDRV_CTL_ELEM_ACCESS_MIC_LED

ALSA: control - add generic LED API

This patchset tries to resolve the diversity in the audio LED
control among the ALSA drivers. A new control layer registration
is introduced which allows to run additional operations on
top of the elementary ALSA sound controls.

A new control access group (three bits in the access flags)
was introduced to carry the LED group information for
the sound controls. The low-level sound drivers can just
mark those controls using this access group. This information
is not exported to the user space, but user space can
manage the LED sound control associations through sysfs
(last patch) per Mark's request. It makes things fully
configurable in the kernel and user space (UCM).

The actual state ('route') evaluation is really easy
(the minimal value check for all channels / controls / cards).
If there's more complicated logic for a given hardware,
the card driver may eventually export a new read-only
sound control for the LED group and do the logic itself.

The new LED trigger control code is completely separated
and possibly optional (there's no symbol dependency).
The full code separation allows eventually to move this
LED trigger control to the user space in future.
Actually it replaces the already present functionality
in the kernel space (HDA drivers) and allows a quick adoption
for the recent hardware (ASoC codecs including SoundWire).

snd_ctl_led            24576  0

The sound driver implementation is really easy:

1) call snd_ctl_led_request() when control LED layer should be
   automatically activated
   / it calls module_request("snd-ctl-led") on demand /
2) mark all related kcontrols with
        SNDRV_CTL_ELEM_ACCESS_SPK_LED or
        SNDRV_CTL_ELEM_ACCESS_MIC_LED

Amadeusz Sławiński f4b4bdf29a ALSA: hda: Revert "ALSA: hda: Allow setting preallocation again for x86"
This reverts commit f8e4ae10de ("ALSA: hda: Allow setting
preallocation again for x86").

The reverted commit itself is a revert of c31427d0d2 ("ALSA: hda: No
preallocation on x86 platforms"). It was needed because HDA allowed very
big allocations, up to 1GB per stream. However as previous commit in
this series changes maximum allowed allocation per stream to 4MB, we can
safely revert it back.

On systems where there are a lot of FrontEnds, when
CONFIG_SND_HDA_PREALLOC_SIZE != 0  ALSA core allocates memory for each
FE, which may cause out of memory problems due to per card limit. Force
config to 0 on X86, so memory will be allocated on as needed basis.

Mark Pearson a14a621999 ALSA: hda: ignore invalid NHLT table
On some Lenovo systems if the microphone is disabled in the BIOS
only the NHLT table header is created, with no data. This means
the endpoints field is not correctly set to zero - leading to an
unintialised variable and hence invalid descriptors are parsed
leading to page faults.

The Lenovo firmware team is addressing this, but adding a check
preventing invalid tables being parsed is worthwhile.

Tested on a Lenovo T14.

Pierre-Louis Bossart 08c2a4bc9f ALSA: hda: move Intel SoundWire ACPI scan to dedicated module
The ACPI scan capabilities is called from the intel-dspconfig as well
as the SOF/HDaudio drivers. This creates dependencies and randconfig issues
when HDaudio and SOF/SoundWire are not all configured as modules.

To simplify Kconfig dependencies between HDAudio, SoundWire, SOF and
intel-dspconfig, move the ACPI scan helpers to a dedicated
module. This follows the same idea as NHLT helpers which are already
handled as a dedicated module.

The only functional change is that the kernel parameter to filter
links is now handled by a different module, but that was only provided
for developers needing work-arounds for early BIOS releases.

Pierre-Louis Bossart a864e8f159 ALSA: hda: intel-nhlt: verify config type
Multiple bug reports report issues with the SOF and SST drivers when
dealing with single microphone cases.

We currently read the DMIC array information unconditionally but we
don't check that the configuration type is actually a mic array.

When the DMIC link does not rely on a mic array configuration, the
recommendation is to check the format information to infer the maximum
number of channels, and map this to the number of microphones.

This leaves a potential for a mismatch between actual microphones
available in hardware and what the ACPI table contains, but we have no
other source of information.

Note that single microphone configurations can alternatively be
handled with a 'mic array' configuration along with a 'vendor-defined'
geometry.

Hans de Goede 5427c7d629 ALSA: hda: intel-dsp-config: Add SND_INTEL_BYT_PREFER_SOF Kconfig option
The kernel has 2 drivers for the Low Power Engine audio-block on
Bay- and Cherry-Trail SoCs. The old SST driver and the new SOF
driver. If both drivers are enabled then the kernel will default
to using the old SST driver, unless told otherwise through the
snd_intel_dspcfg.dsp_driver module-parameter.

Add a boolean SND_INTEL_BYT_PREFER_SOF Kconfig option, which when set to Y
will make the kernel default to the new SOF driver instead.
The option defaults to n, preserving the current behavior.

Making this configurable will help distributions such as Fedora:
https://fedoraproject.org/w/index.php?title=Changes/SofDefaultForIntelLpe
to test using SOF on BYT/CHT during the transition phase where we
have both drivers (eventually the old driver and this option will
be removed).

Note that this drops the acpi_config_table[] containing 2 entries per ACPI
hardware-id if both drivers are enabled. snd_intel_acpi_dsp_find_config()
will always return the first hit, so we only need a single entry with the
flags value set depending on the Kconfig settings.

Kai Vehmanen f9e5fd1b66 ALSA: hda: add link_power op to hdac_bus_ops
The extended HDA bus (hdac_ext) provides interfaces for more
fine-grained control of individual links than what plain HDA
provides for. Links can be powered off when they are not used and if
all links are released, controller can shut down the command DMA.

These interfaces are currently not used by common HDA codec drivers.
When a HDA codec is runtime suspended, it calls snd_hdac_codec_link_down(),
but there is no link to the HDA extended bus, and on controller side
the links are shut down only when all codecs are suspended.

This patch adds link_power() to hdac_bus ops. Controllers using the HDA
extended core, can use this to plug in snd_hdac_ext_bus_link_power() to
implement more fine-grained control of link power.

No change is needed for plain HDA controllers nor to existing HDA
codec drivers.

Mirror capabilities provided for PCI devices, so that distributions

parameters and DMI tables instead of forcing a build-time selection.

The "legacy" option supported for HDaudio has no meaning here and will
be ignored.

The 'SST' driver based on closed-source firmware has the priority to
avoid any impact on users, and the choice to use SOF is strictly
opt-in. This may change at some point when the 'SST' driver is
deprecated on Baytrail/Cherrytrail.

ASoC: hdac: make SOF HDA codec driver probe deterministic
To provide backward compatibility to older systems, the SOF HDA driver
allows user to specify which HDMI codec driver to use at runtime via
kernel parameter. This mechanism has a subtle flaw in that it assumes
the codec drivers not to be loaded when the SOF PCI driver is loaded.

The problem is rooted in use of the hdev->type field.
snd_hdac_ext_bus_device_init() initializes this field to HDA_DEV_ASOC.
This signals the HDA core that ASoC drivers should be considered in
driver matching (hda_bus_match()). The SOF and SST drivers continue by
overriding this field to HDA_DEV_LEGACY and proceeding to load driver
modules with request_module(). Correct drivers will get loaded and
attached.

If however the codec drivers are already loaded when
snd_hdac_ext_bus_device_init() is called, the matching will not work as
expected as device type is still set to HDA_DEV_ASOC. Specifically if
hdac-hdmi is attached when machine driver is configured to use hdac-hda,
this leads to out-of-bounds memory access in
hda_dsp_hdmi_build_controls().

Fix the issue by adding codec type as a parameter to
snd_hdac_ext_bus_device_init() and ensuring type is set correctly from
the start.

Rander Wang 13774d81f3 ALSA: hda: fix a runtime pm issue in SOF when integrated GPU is disabled
In snd_hdac_device_init pm_runtime_set_active is called to
increase child_count in parent device. But when it is failed
to build connection with GPU for one case that integrated
graphic gpu is disabled, snd_hdac_ext_bus_device_exit will be
invoked to clean up a HD-audio extended codec base device. At
this time the child_count of parent is not decreased, which
makes parent device can't get suspended.

This patch calls pm_runtime_set_suspended to decrease child_count
in parent device in snd_hdac_device_exit to match with
snd_hdac_device_init. pm_runtime_set_suspended can make sure that
it will not decrease child_count if the device is already suspended.

Sameer Pujar 67ae482a59 ALSA: hda: add member to store ratio for stripe control
Stripe control programming is governed by following formula, which is
referenced from the HD Audio specification(Revision 1.0a).
  { ((num_channels * bits_per_sample) / number of SDOs) >= 8 }

Currently above is implemented in snd_hdac_get_stream_stripe_ctl().
This patch introduces a structure member to store the default factor
of '8'. If any HW wants to use a different value, this member can be
easily updated.

Cezary Rojewski 0d283287a4 ALSA: hda: Refactor Intel NHLT init
NHLT fetch based on _DSM prevents ACPI table override mechanism from
being utilized. Make use of acpi_get_table to enable it and get rid of
redundant code. In consequence, NHLT can be overridden just like any
other ACPI table, e.g.: DSDT or SSDT.

Change has been verified on all Intel AVS architecture platforms, RVP
and production laptops both.

Change possible due to addition of NHLT signature to the list of
standard ACPI tables:
https://patchwork.kernel.org/patch/11463235/

Override helps not only with debug purposes but also allows user for
table adjustment when one found on their production hardware is invalid.
Shared official NHLT spec is now available to community at:
https://01.org/blogs/intel-smart-sound-technology-audio-dsp

NHLT support for iASL is still ongoing subject but should be available
in nearest future.

Takashi Iwai f8e4ae10de ALSA: hda: Allow setting preallocation again for x86
The commit c31427d0d2 ("ALSA: hda: No preallocation on x86
platforms") changed CONFIG_SND_HDA_PREALLOC_SIZE setup and its default
to zero for x86, as the preallocation should work almost all cases.
However, this expectation was too naive; some applications try to
allocate as the max buffer size as possible, and it leads to the
memory exhaustion.  More badly, the commit changed the kconfig no
longer adjustable for x86, so you can't fix it statically (although it
can be still adjusted via procfs).

So, practically seen, it's more recommended to set a reasonable limit
for x86, too.  This patch follows to that experience, and changes the
default to 2048 and allow the kconfig adjustable again.

Pierre-Louis Bossart 0650857570 ALSA: hda: add autodetection for SoundWire
When an ACPI companion device is present and the SoundWire link mask
information is available, use SoundWire instead of legacy HDA or
Skylake drivers.

The SOF driver is selected when SoundWire or DMIC are detected. There
is no precedence at this level. In the SOF driver proper, SoundWire
will be handled first since it is mutually exclusive with HDaudio.

Known devices with an existing DMI quirk bypass this detection to
avoid any dependency on ACPI/DSDT tables.

Takashi Iwai 44eeb081b8 ALSA: hda: Use scnprintf() for printing texts for sysfs/procfs
Some code in HD-audio driver calls snprintf() in a loop and still
expects that the return value were actually written size, while
snprintf() returns the expected would-be length instead.  When the
given buffer limit were small, this leads to a buffer overflow.

Use scnprintf() for addressing those issues.  It returns the actually
written size unlike snprintf().

ALSA: hda: do not override bus codec_mask in link_get()
snd_hdac_ext_bus_link_get() does not work correctly in case
there are multiple codecs on the bus. It unconditionally
resets the bus->codec_mask value. As per documentation in
hdaudio.h and existing use in client code, this field should
be used to store bit flag of detected codecs on the bus.

By overwriting value of the codec_mask, information on all
detected codecs is lost. No current user of hdac is impacted,
but use of bus->codec_mask is planned in future patches
for SOF.

Mohan Kumar 7faa26c1bb ALSA: hda: Reset stream if DMA RUN bit not cleared
Tegra HDA has FIFO size which can hold upto 10 audio frames to support
DVFS. When HDA DMA RUN bit is set to 0 to stop the stream, the DMA RUN
bit will be cleared to 0 only after transferring all the remaining audio
frames queued up in the fifo. This is not in sync with spec which states
the controller will stop transmitting(output) in the beginning of the
next frame for the relevant stream.

The above behavior with Tegra HDA was resulting in machine check error
during the system suspend flow with active audio playback with below kernel
error logs.
[ 33.524583] mc-err: [mcerr] (hda) csr_hdar: EMEM address decode error
[ 33.531088] mc-err: [mcerr] status = 0x20000015; addr = 0x00000000
[ 33.537431] mc-err: [mcerr] secure: no, access-type: read, SMMU fault: none

This was due to the fifo has more than one audio frame when the DMA
RUN bit is set to 0 during system suspend flow and the timeout handling in
snd_hdac_stream_sync() was not designed to handle this scenario. So the
DMA will continue running even after timeout hit until all remaining
audio frames in the fifo are transferred, but the suspend flow will try
to reset the controller and turn off the hda clocks without the knowledge
of the DMA is still running and could result in mc-err.

The above issue can be resolved by doing stream reset with the help of
snd_hdac_stream_reset() which would ensure the DMA RUN bit is cleared
if the timeout was hit in snd_hdac_stream_sync().

Takashi Iwai c31427d0d2 ALSA: hda: No preallocation on x86 platforms
Like many other drivers, HD-audio drivers also do PCM buffer
preallocation to assure the buffer pages allocated at the early boot
stage.  This step is useful for platforms that may fail to allocate
the PCM hardware buffers -- which is mostly for either large
continuous pages or with the specific DMA mask (like emu10k1).

OTOH, when a buffer is allocated as SG-buffer and the DMA mask is
either 32 or 64 bits, the allocation almost never fails unless it hits
the real OOM situation.  In such a case, we don't need the
preallocation inevitably unlike the cases above.

That said, we may drop the preallocation for HD-audio that does
allocate via SG-buffers, and the patch achieves it.

However, there is one caveat: the buffer allocation behavior depends
on CONFIG_SND_DMA_SGBUF, and it falls back to the continuous pages
when it's not set.  And, currently this SG buffer allocation is
enabled only on x86 platforms.  So, covering those fall-outs, the
patch adjusts CONFIG_SND_HDA_PREALLOC_SIZE depending on the condition,
and keeps the old behavior as-is for non-x86 platforms.

On x86, the kconfig item is no longer adjustable but always set to
zero for disabling the preallocation.  You can still enable the
preallocation via procfs interface at any time later, too.
