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.

snd_hdac_ext_stop_streams() has really nothing to do with the
extension, it just loops over the bus streams.

Move it to the hdac_stream layer and rename to remove the 'ext'
prefix and add the precision that the chip will also be stopped.

Libin Yang 385f287f98 ALSA: hda: intel-sdw-acpi: harden detection of controller
The existing code currently sets a pointer to an ACPI handle before
checking that it's actually a SoundWire controller. This can lead to
issues where the graph walk continues and eventually fails, but the
pointer was set already.

This patch changes the logic so that the information provided to
the caller is set when a controller is found.

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.

 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.

Takashi Iwai 9b838a3c32 ALSA/ASoC/SOF/SoundWire: fix Kconfig issues
In January, Intel kbuild bot and Arnd Bergmann reported multiple
 issues with randconfig. This patchset builds on Arnd's suggestions to
 
 a) expose ACPI and PCI devices in separate modules, while sof-acpi-dev
 and sof-pci-dev become helpers. This will result in minor changes
 required for developers/testers, i.e. modprobe snd-sof-pci will no
 longer result in a probe. The SOF CI was already updated to deal with
 this module dependency change and introduction of new modules.
 
 b) Fix SOF/SoundWire/DSP_config dependencies by moving the code
 required to detect SoundWire presence in ACPI tables to sound/hda.
