571d1fe871 topology: pre-process-object: add data section for attributes with token reference
Objects that have attributes with token_ref need
to have separate SectionData and SectionVendorTuples
for each unique token_ref based on the attribute_sets
in the object's attribute_set_list.

Add the tplg_pp_add_object_data()
function to add the data[] refs in the object and also
the respective SectionData and SectionVendorTuples.

For example for the pga object:

Object.Widget.pga."0" {
	pipeline_id 2
	format s24le
	type pga
	no_pm 1
	uuid    "7e:67:7e:b7:f4:5f:88:41:af:14:fb:a8:bd:bf:8"
	period_sink_count 2
	period_source_count 2
	ramp_step_ms 250
        ramp_step_type "linear"
	mixer.0 {
		....
	}
	mixer.0.name "2 Master Playback Volume"
}

The following sections will be added:
SectionWidget.'pga.2.0' {
	index 2
	type pga
	no_pm 1
	mixer [
		"2 Master Playback Volume"
	]
	bytes [
	]
	data [
		"pga.2.0.sof_tkn_comp.word"
		"pga.2.0.sof_tkn_comp.string"
		"pga.2.0.sof_tkn_comp.uuid"
		"pga.2.0.sof_tkn_volume.word"
	]
}

SectionData."pga.2.0.sof_tkn_comp.word" {
	tuples	"pga.2.0.sof_tkn_comp.word"
}

SectionData."pga.2.0.sof_tkn_comp.string" {
	tuples	"pga.2.0.sof_tkn_comp.string"
}

SectionData."pga.2.0.sof_tkn_comp.uuid" {
	tuples	"pga.2.0.sof_tkn_comp.uuid"
}

SectionData."pga.2.0.sof_tkn_volume.word" {
	tuples	"pga.2.0.sof_tkn_volume.word"
}

SectionVendorTuples."pga.2.0.sof_tkn_comp.word" {
	tokens	"sof_tkn_comp"
	tuples."word" {
		period_source_count	"2"
		period_sink_count	"2"
	}
}

SectionVendorTuples."pga.2.0.sof_tkn_comp.string" {
	tokens	"sof_tkn_comp"
	tuples."string" {
		format	"s24le"
	}
}

SectionVendorTuples."pga.2.0.sof_tkn_comp.uuid" {
	tokens	"sof_tkn_comp"
	tuples."uuid" {
		uuid	"7e:67:7e:b7:f4:5f:88:41:af:14:fb:a8:bd:bf:8"
	}
}

	tokens	"sof_tkn_volume"
	tuples."word" {
		ramp_step_ms	"250"
		ramp_step_type	"0"
	}
}

Note that the ramp_step_type of "linear" is converted
to the tuple value 0.

d999c267d3 topology: pre-process-object: Add support for processing Manifest object
The pre-processor converts the Topology2.0 objects into
the relevant sections by looking for attributes defined
in the template config for the section and reading the
attribute values from the object instance config.

The structure struct build_function_map contains the
mapping of the build function to use for each object
based on the type and name for the class that the object
belongs to. The manifest object is the simplest with
no attributes. So, the build function simply creates
a new Section called SectionManifest which will be
populated with the data section in the following patches.

1ca07d8dbc topology: pre-process-object: construct object name from its constructor attributes
An object's name is derived from its constructor attribute
values separated by '.'. For example, the name for the
host widget objects is derived from its index and direction
attribute values as follows:
Object.Widget.host."playback" {
	index 2
}

The name for the host widget object would be host.2.playback.

Alternatively, if the object has a name attribute, the class
definition may skip the constructor attributes and the name attribute
value will be used instead.

b2e85be668 topology: pre-process-object: check attribute validity
Attributes can have constraints set for valid values, min
or max values. If the attribute value is set in an object,
the value must be validated against the set constraints.

An example for attribute constraint would be:
DefineAttribute."direction" {
		constraints {
			valid_values [
				"playback"
				"capture"
			]
			tuple_values [
				0
				1
			]
		}
}

where the tuple_values array would translate the valid_values of
playback as 0 and capture as 1.

Object attributes can be set in multiple places. Search for
the attribute value in the following order:
1. Value set in object instance
2. Default value set in the object's class definition
3. Inherited value from the parent object
4. Value set in the object instance embedded in the parent object
5. Value set in the object instance embedded in the parent class definition

Mandatory attributes must be found in one of the above, resulting
in an error if not found.

4d413567b0 topology: pre-process-object: Add support for pre-processing Objects
Add support for pre-processing object instances in the input
config. An object's attributes can be set in multiple places
such as, within the object instance, default values in the class
defnition, inherited from a parent object or explicitly set
in a parent object. Before converting the object config into
the relevant section in the existing syntax, all the attribute
values must be consolidated into one place so that it is easy
to verify if all mandatory attributes are set.
Also, the name of the object will be constructed from the
attributes defined in the attributes.constructor[] config
in the class definition and the unique attribute's value
must be set from the value passed in the object instance.

This patch create a temporary config for each object instance
and populates its unique attribute value. The rest of the steps
will be added in the following patches.

e3ad68b185 topology: pre-process-class: add function to convert valid attribute values to integer tuple values

to integer tuple values before it is appended to the

For ex, the buffer widget object's "caps" attribute has the
following definition:
	DefineAttribute."caps" {
		type	"string"
		# Token reference and type
		token_ref	"sof_tkn_buffer.word"
		constraints {
			value_ref	"sof_tkn_mem"
			valid_values [
				"dai"
				"host"
				"pass"
				"comp"
			]
			tuple_values [
				113
				113
				113
				65
			]
		}
	}

Depending on the user input, the value string values for "caps"
will be converted to the appropriate tuple values.

a82058e6ec topology: Add support for pre-processing Topology2.0 syntax
This patch adds support for pre-processing the Topology2.0.
The '-p' switch add pre-processing support during compilation
and the '-P' switch is for converting the Topology2.0
configuration file into the existing syntax.

Topology2.0 is a high level keyword extension on top of the existing ALSA
conf topology format designed to:

1) Simplify the ALSA conf topology definitions by providing high level
   "classes" so topology designers need to write less config for common
   object definitions.

2) Allow simple reuse of objects. Define once and reuse (like M4) with
   the ability to alter objects configuration attributes from defaults.

3) Allow data type and value verification. This is not done today and
   frequently crops up in FW bug reports.

Common Topology Classes
-----------------------

Topology today has some common classes that are often reused throughout
with slightly altered configurations. i.e. widgets (components),
pipelines, dais and controls.

Topology2.0 introduces the high level concept of reusable "class" like
definition for that can be used to create topology objects.

Common Topology Attributes
--------------------------
Topology defines a lot of attributes per object with different types
and constraints. Today there is no easy way to validate type or
constraints and this can lead to many hard to find problems in FW at
runtime.

A new keyword "DefineAttribute" has been added to define attribute
constraints such as min value, max value, enum_values etc. This
then allows alsatplg to validate each topology object attribute.

Topology Classes define the list of attributes that they use and
whether the attribute is mandatory, can be overridden by parent users
or is immutable. This also helps alsatplg emit the appropriate errors
for attribute misuse.

Class constructor attributes
----------------------------
Some attributes in the class definition are declared as constructor
attributes and these will be used to construct the name of the object.
For ex: for the host widget, the index and direction are constructor
attributes and the name for the widget is derived as follows:
host.1.playback or host.2.capture etc.

Attribute Inheritance:
----------------------
One of the key features of Topology2.0 is how the attribute values are
propagated from a parent object to a child object. For ex: a pipeline
object can pass down the pipeline_id attribute to all its widgets.
Inheritance is implicit when an object and its embedded child objects
have matching names for a attribute/argument. Attribute values
set explicitly in an object instance always has precedence over
the values inherited from the parent object.

elapse since no event is expected to occur. However, as a result to
applying commit e5e6a7838b, -ETIMEDOUT returns in the case and
the caller handles it as error. This results in disorder of the
scheduling model.

c9e9a79c6c aplay: avoid any further PCM writing if in abort
Terminating stream with CTRL-C will set in_aborting flag which is used to leave any
write/read loop on the ALSA device.
After ending the read/write loop aplay tries to drain the stream which is not required and can also lead to malfunctions:
-If user interrupts a blocked/non responsive PCM (e.g. usb uac2 gadget which does not consume data
due to stream stopped by host) it will successfully terminate the write loop but will hang again in drain call.
This would require to hit CTRL-C again to unblock which should be avoided.
Aplay currently anyhow allows signal handler to get invoked only once.

00be486131 speaker-test: add support for S24_LE and S24_BE
These formats are sometimes advertised by drivers, e.g. SOF.
The format is 3 bytes packed in 32-bit container, with the MSB zeroed
out.

sample: 0x00123456

S24_LE format:
b0 56
b1 34
b2 12
b3 00

S24_BE format:
b0 00
b1 12
b2 34
b3 56

I only tested the S24_LE format with the SOF driver, S24_BE was added
for symmetry only.

92004425fc axfer: test: use memfd_create() for mapper-test
The mapper test program writes audio data frame to files, and read
them from the files, then validate them. For the operations, usage of
any in-memory file is good to shorten time of overall operations.

This commit uses shm by memfd_create().

5ab26fbc14 axfer: test: minor code arrangement to use the same file descriptor for mappter-test
In mapper test program, two set of file descriptors open to the same files
for container builder and parser contexts, however the same file descriptor
is available for the case.

This commit arranges to use the same file descriptor for the contexts.

2314d746b9 axfer: test: use memfd_create() for container-test
The container test program writes audio data frame to file, and read
them from the file, then validate them. For the operations, usage of
any in-memory file is good to shorten time of overall operations.

This commit uses shm via memfd_create(). As a result, overall time to
run is shorten one half of before, depending on machine environment.

I note that we can achieve the same result by using O_TMPFILE flag in
open(2) system call, however the implementation of O_TMPFILE is to add
i-node without name on underling file system, thus it has overhead
depending on implementation in each file system. On the other hand,
memfd_create() is directly relevant to shm and expected to be less
overhead.

e9a4d32e29 autotools: preparation to use memfd_create(2)
This is a preparation to use memfd_create(2) system call for test programs
of axfer. The system call was introduced at Linux kernel v3.17 and
relatively new.

For safe, this commit adds detection of memfd_create() in autotools side
so that application can handle the case not to detect.

5cb67b5ab6 axfer: open file descriptor outside of container module
Internal container module operates file descriptor to media file. For
this purpose, the structure has fd member and any file operation is done
internally. However, the case to use special file descriptor such as
memfd requires to maintain file descriptor externally.

This commit opens file descriptor outside of container module. The
internal APIs to initialize container get an argument for the file
descriptor instead of file path.
