Subject: ASoC: SOF: core: allow module parameter to override dma trace Kconfig

Most distributions do not enable the SOF developer options and
specifically the DMA trace. This is problematic for end-user/community
support since the sof-logger tool cannot extract valuable information.

Conversely in rare cases the DMA trace can lead to Heisenbugs by
creating more traffic to system memory and more interrupts.

This patch changes the logic so that the Kconfig value is used as a
default value for a module parameter, but this value can be changed as
needed. Users can override the distro DMA trace selection.

Subject: ASoC: SOF: control: fix a typo in put operations for kcontrol

SOF_CTRL_TYPE_VALUE_CHAN_SET should be used for put operations
for consistency. The current use of _GET is obviously incorrect
but _GET and _SET result in the same action so there is no
functional change introduced by this patch.

Subject: ASoC: SOF: Handle control change notification from firmware

If the value/data associated with a control changes in SOF it will send a
notification (SOF_IPC_GLB_COMP_MSG with SOF_IPC_COMP_GET_VALUE/DATA).

We have support for binary volatile control type, but we might have
features where enum/switch/volume changes. Re-implementing everything as
volatile as well would be not much of a gain for several reasons:
- volatile controls would do an IPC all the time, regardless if there is a
  need or not.
- We still don't have notification which forces userspace to continuously
  poll.

When such notification arrives we use snd_ctl_notify_one() to signal
userspace about the change.

The kernel is prepared for two types of notification:
- the notification carries the new data for the control (num_elems != 0)
The new value/data is copied to the control's local data

- blank message about a change
The new flag for the scontrol (comp_data_dirty) is set and when next
time user space reads the value via the kcontrol's get callback we will
refresh the control's local data from the firmware.

Subject: ASoC: SOF: intel: Do no initialize resindex_dma_base

.resindex_dma_base is not used by the code and in all instances it is set
to -1.
To make it possible to remove it from the sof_dev_desc struct, first remove
all references from the intel drivers (initialization).

Subject: ASoC: SOF: Intel: hda-dsp: Declare locally used functions as static

The following functions can be made static as they are only used locally:
hda_dsp_core_reset_enter
hda_dsp_core_reset_leave
hda_dsp_core_stall_reset
hda_dsp_core_power_up
hda_dsp_core_power_down
hda_dsp_core_is_enabled

The hda_dsp_ipc_int_disable is also only used within hda-dsp.c, but for
symmetry for hda_dsp_ipc_int_enable (used by hda-loader.c) leave it as it
is.

Since the load_firmware callback in snd_sof_dsp_ops is mandatory and it

Move the snd_sof_load_firmware() wrapper to ops.h as inline and drop the
check of sof_ops(sdev)->load_firmware

Subject: ASoC: SOF: ipc: Remove snd_sof_dsp_mailbox_init()

The snd_sof_dsp_mailbox_init() is called only from sof_get_windows()
to set the sdev->dsp_box.offset/size and sdev->host_box.offset/size

Instead of using a function, set the offsets and sizes like we do for the
other boxes in sof_get_windows().

Subject: ASoC: SOF: core: Do not use 'bar' as parameter for block_read/write

The use of bar in the core poses limits on the portability of the code
to other, non iomapped platforms.
To make the API more generic, remove the use of 'bar' as parameter
for the block copy API.

Subject: ASoC: SOF: debug: Add generic API and ops for DSP regions

Add new debugfs_add_region_item along with a generic wrapper
snd_sof_debugfs_add_region_item() to abstract away the DSP regions related
debugfs support.

At the same commit add iomem based generic implementation for the new ops

PROBE_INIT would show up as:

ipc tx: 0xc0010000: unknown GLB command
ipc tx succeeded: 0xc0010000: unknown GLB command

Add code to handle  the probe messages to have human readable output

Subject: ASoC: SOF: compress: move and export sof_probe_compr_ops

sof_probe_compr_ops are not platform-specific. So move
it to common compress code and export the symbol. The
compilation of the common compress code is already dependent
on the selection of CONFIG_SND_SOC_SOF_DEBUG_PROBES, so no
need to check the Kconfig section for defining sof_probe_compr_ops
again.

Subject: ASoC: SOF: probe: Merge and clean up the probe and compress files

The probe debug functionality is implemented via compress support and it
was spread across two set of files:
probe.c/h
compress.c/h

Merge the two files into sof-probes.s/h and clean them up by removing
unused struct definitions, functions. We can also move most of the
functions static as they are only used internally.

Subject: ASoC: SOF: Intel: Rename hda-compress.c to hda-probes.c

The hda-compress.c is implementing the SOF probe support for intel HDA
platforms using compress API.

To avoid the confusion, rename it to reflect this.

Subject: ASoC: SOF: sof-probes: Correct the function names used for
 snd_soc_cdai_ops

The snd_soc_cdai_ops have startup and shutdown callbacks defined unlike
the component callbacks where open and free is used.

Subject: ASoC: SOF: ipc: Remove redundant error check from
 sof_ipc_tx_message_unlocked

If the snd_sof_dsp_send_msg() failed then we have already returned from
sof_ipc_tx_message_unlocked() with the error message.

There is no need to check if ret is really 0 after this and we can return
directly the return value from tx_wait_done()

At the same time make the remaining checks for error (ret) to match.

The initial hdac_stream code was adapted a third time with the same
locking issues. Move the spin_lock outside the loops and make sure the
fields are protected on read/write.

If an invalid stream is passed to snd_sof_ipc_msg_data() it won't
fill the provided object with data. The caller has to be able to

Subject: ASoC: SOF: ipc: Make the error prints consistent in tx_wait_done()

If we get an error on reply (msg->reply_error) then we should print the
error value out.

At the same time extend the print to include the message size as well and
do the same in case of a timeout.

Subject: ASoC: SOF: Change SND_SOC_SOF_TOPLEVEL from config to menuconfig

We have growing number of options under SND_SOC_SOF_TOPLEVEL as SOF
adaptation is growing (Intel, NXP, AMD and Mediatek) and new features are
added.
It will make the menuconfig user experience much cleaner if we move the
SOF options under a separate page.

Subject: ASoC: topology: change the complete op in snd_soc_tplg_ops to return
 int

In the SOF driver, the operations performed in the complete callback
can fail and therefore topology loading should return an error in
such cases. So, change the signature of the complete op
in struct snd_soc_tplg_ops to return an int to return the error.

Also, amend the complete callback functions in the SOF driver and
the SKL driver to conform with the new signature.

Subject: ASoC: SOF: control: Add access field in struct snd_sof_control

Add a new field to save the access setting for all controls
in struct snd_sof_control. This will be used to ensure that
only widgets belonging to static pipelines have volatile
controls.

Subject: ASoC: SOF: topology: Add new token for dynamic pipeline

Today, we set up all widgets required for all PCM streams
at the time of topology parsing even if they are not
used. An optimization would be to only set up the widgets
required for currently active PCM streams. This would give
the FW the opportunity to power gate unused memory blocks,
thereby saving power.

For dynamic pipelines, the widgets in the connected DAPM path
for each PCM will need to be set up at runtime. This patch
introduces a new token, DYNAMIC_PIPELINE, for scheduler type
widgets that indicate whether a pipeline should be set up
statically during topology load or at runtime when the PCM is
opened. Introduce a new field called dynamic_pipeline_widget
in struct snd_sof_widget to save the value of the parsed token.

The token is set only for the pipeline (scheduler type)
widget and must be propagated to all widgets in the same
pipeline during topology load. Introduce another field called
pipe_widget in struct snd_sof_widget that saves the pointer to
the scheduler widget with the same pipeline ID as that of the
widget. This field is populated when the pipeline completion
callback is invoked during topology loading.

Subject: ASoC: SOF: sof-audio: add helpers for widgets, kcontrols and dai
 config set up

Refactor the existing code to use helper functions to
set up/free widgets, send dai config and set up kcontrols for
widgets. These will be reused later on for setting up widgets in
the connected DAPM widgets list for a particular PCM when the
dynamic pipeline feature is implemented.

Subject: ASoC: SOF: Add new fields to snd_sof_route

Add two new fields to save the source widget and sink widget
pointers in struct snd_sof_route to make it easier to look up
routes by source/sink widget. Also, add a flag to indicate
if the route has been set up in the DSP. These will be used
when the dynamic pipeline feature is implemented and routes
will have to be set up at run time.

Also, add a new sof_tear_down_pipelines() callback, that will
used to reset the set up status for all routes during suspend.

Subject: ASoC: SOF: Don't set up widgets during topology parsing

In preparation for supporting dynamic pipelines, move the
widget setup, DAI config IPCs to the complete callback
during topology loading. For current topology where all
the pipelines are static, all the pipelines will be set up
during complete. For topologies with dynamic and static pipelines,
this will enable setting up only the static ones  during
topology loading. Reuse the sof_restore_pipelines() function for
this purpose and rename it to sof_set_up_pipelines().

From 8b0014169254513bda914ba5d49a09458a919488 Mon Sep 17 00:00:00 2001
From: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>
Date: Mon, 27 Sep 2021 15:05:14 +0300
Subject: ASoC: SOF: Introduce widget use_count

Add a new field, use_count to struct snd_sof_widget to keep track
of the usage count for each widget. Since widgets can belong to
multiple pipelines, this field will ensure that the widget
is setup only when the first pipeline that needs it is started
and freed when the last pipeline that needs it is stopped. There is
no need to protect the widget use_count access as the core already
handles mutual exclusion at the PCM level.
Add a new helper sof_widget_free() to handle freeing the SOF
widgets and export the sof_widget_setup/free() functions.

Subject: ASoC: SOF: Intel: hda: make sure DAI widget is set up before IPC

With the implementation of the dynamic pipeline feature, widgets
will only be setup when a PCM is opened during the
hw_params ioctl. The BE hw_params callback is responsible for
sending the DAI_CONFIG for the DAI widgets in the DSP.
With dynamic pipelines, the DAI widgets will need to set up
first before sending the DAI_CONFIG IPC in the BE hw_params.

Update the BE hw_params/hw_free callbacks for all ALH, HDA and SSP
DAIs to set up/free the DAI widget before/after DAI_CONFIG IPC.

Subject: ASoC: SOF: Add support for dynamic pipelines

Add support for dynamic pipelines by modifying the PCM
hw_params ioctl implementation to determine the widgets
required for a PCM stream by querying the list of
connected DAPM widgets. This list is saved as part of
snd_sof_pcm_stream struct and will be used to setup the widgets.

The sof_widget_list_setup/free routines setup and free connected
DAPM widgets when a PCM is opened/closed. These routines accept
a list of connected DAPM widgets as input and determine the SOF
widgets, their corresponding pipeline widgets and connections
between them that need to be setup before the PCM is triggered.

Please note that the dynamic pipeline feature will only be enabled
for those pipelines whose dynamic_pipeline_widget flag is set in
topologies. Add a new token called SOF_TKN_SCHED_DYNAMIC_PIPELINE
that when set in topology will be applied to the
dynamic_pipeline_widget flag of the pipeline widget.

Subject: ASoC: SOF: topology: Add kernel parameter for topology verification

Add a kernel debug flag to enable a one-shot topology
verification for all pipelines including the dynamic
ones. If the debug flag is set, all the topology
component loading will be verified during the complete
callback.

The DAI_CONFIG is used for both hw_params and hw_free. Use flags to
specify what stage the configuration applies to.

the DAI_CONFIG IPC may be sent also during the widget setup so each
flag is cleared after the IPC to restore the state.

Subject: ASoC: SOF: Intel: hda-dai: improve SSP DAI handling for dynamic
 pipelines
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In order to keep the widget use_count balanced, make sure the DAI
widgets are allocated once in hw_params and released in hw_free. A
'setup' status flag is used to deal with cases where the .hw_params
callback is invoked multiple times, and likewise with cases where
hw_free is invoked without hw_params being called first (which can
happen if the FE hw_params fails).

In addition, this patch frees the widgets in the suspend transition,
and reallocates them in the .prepare callback. The 'setup' flag helps
in this case differentiate between resume (setup needed) and
xruns (setup not needed).

This balanced operation was not needed previously but will be required
when SOF dynamic pipelines are enabled.

Subject: ASoC: SOF: topology: allow for dynamic pipelines override for debug

For debug and community support, it's useful to expose a kernel
parameter to prevent the use of dynamic pipelines exposed in a
topology file, or conversely to force an existing topology to use
dynamic pipelines.

Add an override bit and an enable bit which is valid only when the
override is set.

For products, the intent is that the topology file defines the
behavior, these two bits are only intended for diagnosis and
performance checks.

Subject: ASoC: SOF: core: debug: force all processing on primary core

The topology file currently provides information on which
pipeline/processing is to be scheduled on which DSP core.

To help diagnose potential issues, this patch provides an override of
the 'core' tokens to use the primary core (typically core0). Of course
this may result in a Core0 activity that exceeds hardware
capabilities, so this should only be used when the total processing
fits on DSP - possibly using firmware mockup processing and stubs.

No new dmesg log was added to avoid adding noise during topology
parsing, but the existing logs will show the primary core being used.

This is strictly for validation/debug, products should NEVER use this
override, the topology is assumed to be the description of the
firmware graph.

 fw_exception

snd_sof_dsp_panic() only prints dsp_dump followed by flushing the DMA trace
buffer.

To retain similar 'sequence' first do an ipc_dump then the dsp_dump and
finally flush the trace buffer in case of fw_exception.

Do not print the dump more than once to keep the kernel log cleaner in case

When the DSP is rebooted due to suspend or runtime_suspend reset the flags
to re-enable the dump prints.

Add also a debug flag to print all dumps to get more coverage if needed.

The new SOF_DBG_DUMP_OPTIONAL flag can be used to mark a DSP dump that
should only be printed when the SOF_DBG_PRINT_ALL_DUMPS sof_core_debug
flag is set, otherwise it should be ignored and not printed.

Subject: ASoC: SOF: intel: hda-loader: Use snd_sof_dsp_dbg_dump() for DSP dump

Do not call directly the hda_dsp_dump(), use the generic wrapper instead
to provide consistent output.

Mark the DSP dumps as optional to not spam the kernel log with the
exception of the last dump in case the DSP fails to run.

Subject: ASoC: SOF: Drop SOF_DBG_DUMP_FORCE_ERR_LEVEL and sof_dev_dbg_or_err

The sof_dev_dbg_or_err() is only used by intel/hda.c when dumping dsp
debug information.
It was used to print the extended rom status in either dev_dbg (during
retries) and finally with dev_err, but other lines were printed with
dev_err regardless.

Since we now only print the dump once, the flag and the macros is no longer
needed.

Subject: ASoC: SOF: ipc: Re-enable dumps after successful IPC tx

The dumps are silenced after an IPC tx timeout by default.
The IPC timeout can indicate severe error (firmware crash) or in some cases
it is less devastating and the firmware remains operational, the timeout
was due to a scheduling spike or other anomaly.

In any case consequent IPC timeouts will not print dumps but if any IPC do
succeed than we should re-enable the dumps to print dumps the next time
a timeout might happen.

Subject: ASoC: SOF: Introduce macro to set the firmware state

Add sof_set_fw_state() macro to wrap the sdev->fw_state management to allow
actions to be taken when certain state is set or when state is changing.

Subject: ASoC: SOF: intel: hda: Drop 'error' prefix from error dump functions

Drop the 'error' prefix printed in hda_dsp_dump_ext_rom_status(),
hda_ipc_irq_dump() and hda_ipc_dump() as it gives no value to the
information we print.

The DSP and IPC dump is marked now, which makes the 'error' prefix more
redundant.

 snd_sof_dev

First thing the pipelines function which have "struct device *dev" as
parameter do is:
struct snd_sof_dev *sdev = dev_get_drvdata(dev);

and in all cases the passed dev is actually coming from sdev->dev.

Skip this steps and pass directly the sdev to all pipelines related
functions as few of them already does this.

Subject: ASoC: SOF: Introduce snd_sof_mailbox_read / snd_sof_mailbox_write
 callbacks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We need to introduce snd_sof_mailbox_{read/write} in order to provide
a generic way for mailbox access. These routines are optional, each
platform can implement their own specific routines.

So far, all platforms use mmapped I/O thus they can use custom made
routines sof_mailbox_read / sof_mailbox_write that use MMIO.

Subject: ASoC: SOF: Make Intel IPC stream ops generic
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This operations should be generic as there is nothing Intel
specific. This works well for NXP i.MX8 stream IPC ops.

We start by moving sof/intel/intel-ipc.c into sof/stream-ipc.c and
rename the functions to be generic.

Notice that we use newly introduced snd_sof_dsp_mailbox_read
instead of sof_mailbox_read, to make sure that we are not
bound to existing MMIO memory access, and we allow platform
to implement their own memory access routines.

Subject: ASoC: SOF: imx: Use newly introduced generic IPC stream ops
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This makes IMX use the newly introduced generic IPC ops
instead of imx specific ones, and removes the old IMX
ipc ops, as they are no longer needed.

Subject: ASoC: SOF: Introduce fragment elapsed notification API
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch prepares the introduction of the compress API with SOF.

After each fragment is accepted by the DSP we need to inform
the userspace applications that they can send the next fragment.
This is done via snd_compr_fragment_elapsed.

Similar with the PCM case, in order to avoid sending an IPC before
the previous IPC is handled we need to schedule a delayed work to
call snd_compr_fragment_elapsed().

See snd_sof_pcm_period_elapsed.

To sum up this patch offers the following API to SOF code:
	* snd_sof_compr_init_elapsed_work
	* snd_sof_compr_fragment_elapsed

Note that implementation for compressed function is in a new file
selected via CONFIG_SND_SOC_SOF_COMPRESS invisible config option.
This option is automatically selected for platforms that support
the compress interface. For now only i.MX8 platforms support this.

For symmetry we introduce snd_sof_pcm_init_elapsed_work to setup
the work struct for PCM case.

From febf5da81ea80fa01e141e3ad35526865681418b Mon Sep 17 00:00:00 2001
From: Rander Wang <rander.wang@intel.com>

Subject: ASoC: SOF: prepare code to allocate IPC messages in fw_ready

The fixed maximum size of IPC message does not allow for large
transfers, e.g. for filter data. Currently such messages will
be divided into smaller pieces and sent to firmware in multiple
chunks. For future IPC, this strategy is not suitable.

The maximum IPC message size is limited by host box size which
can be known when firmware is ready, so the fw_ready callback
can allocate IPC messages with platform-specific sizes instead
of the current fixed-size.

To be compatible with released firmware, current platforms will
still use SOF_IPC_MSG_MAX_SIZE. For future platforms, there will
be a new fw_ready function and the platform-specific allocation
will take place there.
