Compile-testing without PCI just causes warnings:

I tried to fix this in a way that would still allow compile
tests, but it got too ugly, so this just reverts the patch
that allowed it in the first place.
Most architectures do allow enabling PCI, so the value of the
COMPILE_TEST alternative was not very high to start with.

Due to the HW programming sequence requirement that the host

hw_params, the host DMA channel corresponding to the link
DMA channel in use for hostless streams needs to be reserved.
This is achieved by adding a host_reserved flag in the
sof_intel_hda_stream structure which is checked when assigning
a host DMA channel.

The recommended HDA HW programming sequence for setting
the DMA format requires that the link DMA and host DMA
channels be coupled before setting the format. This
change means that host DMA or link DMA channels be
reserved even if only one is used.
Statically assigned link DMA channels would mean that
all the corresponding host DMA channels will need to be
reserved, leaving only a few channels available at run-time.
So, the suggestion here is to switch to dynamically assigning
both host DMA channels and link DMA channels are run-time.
The host DMA channel is assigned when the pcm
is opened as before. While choosing the link DMA channel,
if the host DMA channel corresponding to the link DMA channel
is already taken, the proposed method checks to make
sure that the BE is connected to the FE that has been assigned
this host DMA channel. Once the link DMA channel is assigned,
an IPC is sent to the DSP to set the link DMA channel.
The link DMA channel is freed during hw_free() and also in the
SUSPEND trigger callback. It will be re-assigned when hw_params
are set upon resume.

As part of the suspend flow, a context save IPC message is
sent to the firmware before powering down the DSP. If errors
are met, the suspend flow is aborted with current code.
Change the behaviour such that if firmware returns -EBUSY or
-EAGAIN, return the error codes to PM core as before. The device
is left in active state in this case.
If other errors are reported, print a warning but do not block the
suspend flow. As per interface specification, no valid error can be
returned in this scenario. If the hardware has hit a fatal error and
is not able to respond successfully, best recovery method is to
proceed with suspend and power off the DSP.

firmware will reset its state. After resume, debugfs client's

result in traces read in incorrect order and/or stale data being
read after resume.

has ended, and all trace data has been read. This allows debugfs

ensure proper synchronization with firmware after reopening

Currently on all supported platforms the IPC IRQ thread first signals
the sender when an IPC response is received from the DSP, then unmasks
the IPC interrupt. Those actions are performed without holding any
locks, so the thread can be interrupted between them. IPC timeouts
have been observed in such scenarios: if the sender is woken up and it
proceeds with sending the next message without unmasking the IPC
interrupt, it can miss the next response. This patch takes a spin-lock
to prevent the IRQ thread from being preempted at that point. It also
makes sure, that the next IPC transmission by the host cannot take
place before the IRQ thread has finished updating all the required IPC
registers.

sof_pcm_hw_params() can only be called once to setup the FW hw_params.
So after calling sof_pcm_hw_params(), hw_params_upon_resume flag must
be cleared to avoid multiple invoking sof_pcm_hw_params() by prepare.
For example, after resume, there is an xrun happened, prepare() will
be called. As the hw_params_upon_resume flag is not cleared,
sof_pcm_hw_params() will be called and this will cause IPC timeout.
This patch fixes such issues.

In some configurations, it's a requirement to split the probe in two,
with a second part handled in a workqueue (e.g. for HDMI support
which depends on the DRM modules).
SOF already handles these configurations but the error flow is
incorrect. When an error occurs in the workqueue, the probe has
technically already completed. If we release the resources on errors,
this generates kernel oops/use-after-free when the resources are
released a second time on module removal.

snd_sof_remove() disables the DSP and unmaps the DSP BAR.
Removing topology after disabling the DSP results in a
kernel panic while unloading the pipeline widget. This is
because pipeline widget unload attempts to power down
the core it is scheduled on by accessing the DSP registers.
So, the suggested fix here is to unregister the machine driver
first to remove the topology and then disable the DSP
to avoid the situation described above.
Note that the kernel panic only happens in cases where the
HDaudio link is not managed by the hdac library,
e.g. no codec or when HDMI is not supported.
When the hdac library is used, snd_sof_remove() calls
snd_hdac_ext_bus_device_remove() to remove the codec which
unregisters the component driver thereby also removing the
topology before the DSP is disabled.

The prepare() ioctl for BE dai link gets called both
when the stream is started and when it is resumed from
suspend. SOF uses this ioctl to set the hw params
again only if the stream has been suspended.
When the stream is started, the hw_params ioctl gets called
before prepare() and hw_params is set for the BE dai link.
So the prepare call does not need to do anything further.
When the stream resumes after system suspend, SOF requires
that the hw_params be set again for the BE dai. In order
to determine which streams should set the hw params
during prepare(), an internal flag called "hw_params_upon_resume"
is introduced in struct sof_intel_hda_stream. The flag is set
for hda streams when the sof device suspends and is
cleared after hw_params is set.

The IPC implementation in SOF requires sending IPCs serially: we should
not send a new IPC command to the firmware before we get an ACK (or time
out) from firmware, and the IRQ processing is complete.
snd_pcm_period_elapsed() can be called in interrupt context before
IRQ_HANDLED is returned. When the PCM is done draining, a STOP
IPC will then be sent, which breaks the expectation that IPCs are
handled serially and leads to IPC timeouts.
This patch adds a workqueue to defer the call to snd_pcm_elapsed() after
the IRQ is handled.

Add a simple "fallback" machine driver that can be used to enable SOF
on boards with no codec device. This machine driver can also be forced
for debug/development.

Add support for saving and restoring DSP context in D3 to host DDR.
The suspend callback includes: suspend all pcm's stream that are running,
send CTX_SAVE ipc, drop all ipc's, release trace dma and then
power off the DSP.
And the resume callback performs the following steps: load FW, run FW,
re-initialize trace, restore pipeline, restore the kcontrol values
and finally send the ctx restore ipc to the dsp.
The streams that are suspended are resumed by the ALSA resume trigger.
If the streams are paused during system suspend, they are marked
explicitly so they can be restored during PAUSE_RELEASE.

This patch adds support for real-time DSP logging (timestamped events
and bespoke binary data) for firmware debug. The current solution
relies on DMA transfers to system memory that is then accessed by
userspace tools such as sof-logger. For Intel platforms, two types of
DMAs are currently used (GP-DMA for Baytrail/CherryTrail and HDaudio
DMA for SKL+)
Due to historical reasons, the driver code follows the DSP firmware
conventions and refers to 'traces', but it is currently unrelated to
the Linux trace subsystem. Future solutions will include support for
more advanced hardware (e.g. MIPI Sys-T), additional formats and the
ability to enable/disable specific traces dynamically.

SOF uses topology to define the DAPM graphs and widgets, DAIs, PCMs and set
parameters for init and run time usage. This patch loads topology and
maps it to IPC commands that are build the topology on the DSP.

Add support for exposing PCMs to userspace. PCMs are defined by topology
and the operations in this patch map to SOF IPC calls.
The .get_module_upon_open field is set to allow for module load/unload
tests. There is no risk of the sof-pci/acpi-dev module being removed
while the platform components are in use. This may need to be
revisited when DT platforms are supported.

Add debugFS files that can be used to expose DSP memories and
and peripherals to userspace to assist with firmware debugging.
Since we cannot rely on debugFS, errors are logged but don't stop
execution.
When a resource cannot be read in D3, it is optionally cached on
suspend. Copying memories from IO will increase the suspend latency,
this should only used in engineering builds w/ debug options. This
part will have to be enhanced when support for D0ix states is
provided, currently only D0 and D3 are supported.

SOF exposes regular ALSA Kcontrols that are defined by topology. This
patch converts the Kcontrol IO to DSP IPC.
The current implementation is aligned with previous Intel solutions,
but is not optimal and can be improved:
a) for every get/put the host wakes up the DSP and generates an
IPC. The kernel should cache the values and generate an IPC only when
strictly necessary.
b) the firmware can be implemented to only instantiate the pipelines
and related control-related parts that are needed at a given time, and
power-gate the relevant SRAM blocks.
The development tasks for these two improvements has started, once
validated they will be provided in an update.

The Sound Open Firmware driver core is a generic architecture
independent layer that allows SOF to be used on many different
architectures and platforms. It abstracts DSP operations and IO
methods so that the target DSP can be an internal memory mapped or
external SPI or I2C based device. This abstraction also allows SOF to
be run on many different VMs on the same physical HW.
SOF also requires some data in ASoC PCM runtime data for looking up
SOF data during ASoC PCM operations.
