The topology core + * currently recognises the following object types :- + * + * * Controls (mixer, enumerated and byte) including TLV data. + * * PCMs (Front End DAI & DAI link) + * * DAPM widgets + * * DAPM graph elements. + * * Physical DAI & DAI links + * * Private data for each object type. + * * Manifest (containing count of each object type) + * + *

Topology File Format

+ * + * The topology text format uses the standard ALSA configuration file format to + * describe each topology object type. This allows topology objects to include + * other topology objects as part of their definition. i.e. a TLV data object + * can be shared amongst many control objects that use the same TLV data. + * + * + *

Controls

+ * Topology audio controls can belong to three different types :- + * * Mixer control + * * Enumerated control + * * Byte control + * + * Each control type can contain TLV data, private data, operations and also + * belong to widget objects.
+ * + *
Control Operations
+ * Driver Kcontrol callback info(), get() and put() operations are mapped with + * the CTL ops section in topology configuration files. The ctl ops section can + * assign operations using the standard names (listed below) for the standard + * kcontrol types or use ID numbers (>256) to map to bespoke driver controls.
+ * + * 
+ *
+ *	ops."ctl" {
+ *		info "volsw"
+ *		get "257"
+ *		put "257"
+ *	}
+ *
+ *
+ * + * This mapping shows info() using the standard "volsw" info callback whilst + * the get() and put() are mapped to bespoke driver callbacks.
+ * + * The Standard operations names for control get(), put() and info calls + * are :- + * * volsw + * * volsw_sx + * * volsw_xr_sx + * * enum + * * bytes + * * enum_value + * * range + * * strobe + * +*
Control Access
+ * Controls access can be specified using the "access" section. If no "access" + * section is defined then default RW access flags are set for normal and TLV + * controls. + * + * 
+ *	access [
+ *		read
+ *		write
+ *		tlv_command
+ *	]
+ *
+ * + * The standard access flags are as follows :- + * * read + * * write + * * read_write + * * volatile + * * timestamp + * * tlv_read + * * tlv_write + * * tlv_read_write + * * tlv_command + * * inactive + * * lock + * * owner + * * tlv_callback + * * user + * + *
Control TLV Data
+ * Controls can also use TLV data to represent dB information. This can be done + * by defining a TLV section and using the TLV section within the control. + * The TLV data for DBScale types are defined as follows :- + * + * 
+ *	scale {
+ *		min "-9000"
+ *		step "300"
+ *		mute "1"
+ *	}
+ *
+ * + * Where the meanings and values for min, step and mute are exactly the same + * as defined in driver code. + * + *
Control Channel Mapping
+ * Controls can also specify which channels they are mapped with. This is useful + * for userspace as it allows applications to determine the correct control + * channel for Left and Right etc. Channel maps are defined as follows :- + * + * 
+ *	channel."name" {
+ *		reg "0"
+ *		shift "0"
+ *	}
+ *
+ * + * The channel map reg is the register offset for the control, shift is the + * bit shift within the register for the channel and the section name is the + * channel name and can be one of the following :- + * + * 
+ *  * mono		# mono stream
+ *  * fl 		# front left
+ *  * fr		# front right
+ *  * rl		# rear left
+ *  * rr		# rear right
+ *  * fc		# front center
+ *  * lfe		# LFE
+ *  * sl		# side left
+ *  * sr		# side right
+ *  * rc		# rear center
+ *  * flc		# front left center
+ *  * frc		# front right center
+ *  * rlc		# rear left center
+ *  * rrc		# rear right center
+ *  * flw		# front left wide
+ *  * frw		# front right wide
+ *  * flh		# front left high
+ *  * fch		# front center high
+ *  * frh		# front right high
+ *  * tc		# top center
+ *  * tfl		# top front left
+ *  * tfr		# top front right
+ *  * tfc		# top front center
+ *  * trl		# top rear left
+ *  * trr		# top rear right
+ *  * trc		# top rear center
+ *  * tflc		# top front left center
+ *  * tfrc		# top front right center
+ *  * tsl		# top side left
+ *  * tsr		# top side right
+ *  * llfe		# left LFE
+ *  * rlfe		# right LFE
+ *  * bc		# bottom center
+ *  * blc		# bottom left center
+ *  * brc		# bottom right center
+ *
+ * + *
Control Private Data
+ * Controls can also have private data. This can be done by defining a private + * data section and including the section within the control. The private data + * section is defined as follows :- + * + * 
+ * SectionData."pdata for EQU1" {
+ *	file "/path/to/file"
+ *	bytes "0x12,0x34,0x56,0x78"
+ *	shorts "0x1122,0x3344,0x5566,0x7788"
+ *	words "0xaabbccdd,0x11223344,0x66aa77bb,0xefef1234"
+ *	tuples "section id of the vendor tuples"
+ * };
+ *
+ * The file, bytes, shorts, words and tuples keywords are all mutually + * exclusive as the private data should only be taken from one source. + * The private data can either be read from a separate file or defined in + * the topology file using the bytes, shorts, words or tuples keywords. + * The keyword tuples is to define vendor specific tuples. Please refer to + * section Vendor Tokens and Vendor tuples. + * + * It's easy to use a vendor tuples object to define a C structure instance. + * And a data section can include multiple vendor tuples objects: + * + * 
+ * SectionData."data element name" {
+ *	index "1"	#Index number
+ *	tuples [
+ *		"id of the 1st vendor tuples section"
+ *		"id of the 2nd vendor tuples section"
+ *		...
+ *	]
+ * };
+ *
+ * + *
How to define an element with private data
+ * An element can refer to a single data section or multiple data + * sections. + * + *
To refer to a single data section:
+ * 
+ * Sectionxxx."element name" {
+ *    ...
+ *	data "name of data section"		# optional private data
+ * }
+ *
+ * + *
To refer to multiple data sections:
+ * 
+ * Sectionxxx."element name" {
+ *	...
+ *	data [						# optional private data
+ *		"name of 1st data section"
+ *		"name of 2nd data section"
+ *		...
+ *	]
+ * }
+ *
+ * And data of these sections will be merged in the same order as they are + * in the list, as the element's private data for kernel. + * + * + * + *
Vendor Tokens
+ * A vendor token list is defined as a new section. Each token element is + * a pair of string ID and integer value. And both the ID and value are + * vendor-specific. + * + * 
+ * SectionVendorTokens."id of the vendor tokens" {
+ *	comment "optional comments"
+ *	VENDOR_TOKEN_ID1 "1"
+ *	VENDOR_TOKEN_ID2 "2"
+ *	VENDOR_TOKEN_ID3 "3"
+ *	...
+ * }
+ *
+ * + *
Vendor Tuples
+ * Vendor tuples are defined as a new section. It contains a reference to + * a vendor token list and several tuple arrays. + * All arrays share a vendor token list, defined by the tokens keyword. + * Each tuple array is for a specific type, defined by the string following + * the tuples keyword. Supported types are: string, uuid, bool, byte, + * short and word. + * + * 
+ * SectionVendorTuples."id of the vendor tuples" {
+ *	tokens "id of the vendor tokens"
+ *
+ *	tuples."string" {
+ *		VENDOR_TOKEN_ID1 "character string"
+ *		...
+ *	}
+ *
+ *	tuples."uuid" {			# 16 characters separated by commas
+ *		VENDOR_TOKEN_ID2 "0x01,0x02,...,0x0f"
+ *		...
+ *	}
+ *
+ *	tuples."bool" {
+ *		VENDOR_TOKEN_ID3 "true/false"
+ *		...
+ *	}
+ *
+ *	tuples."byte" {
+ *		VENDOR_TOKEN_ID4 "0x11"
+ *		VENDOR_TOKEN_ID5 "0x22"
+ *		...
+ *	}
+ *
+ *	tuples."short" {
+ *		VENDOR_TOKEN_ID6 "0x1122"
+ *		VENDOR_TOKEN_ID7 "0x3344"
+ *		...
+ *	}
+ *
+ *	tuples."word" {
+ *		VENDOR_TOKEN_ID8 "0x11223344"
+ *		VENDOR_TOKEN_ID9 "0x55667788"
+ *		...
+ *	}
+ * }
+ *
+ * To define multiple vendor tuples of same type, please append some + * characters after the type string ("string", "uuid", "bool", "byte", "short" + * or "word"), to avoid ID duplication in the SectionVendorTuples.
+ * The parser will check the first few characters in ID to get the tuple type. + * Here is an example: + * 
+ * SectionVendorTuples."id of the vendor tuples" {
+ *    ...
+ *	tuples."word.module0" {
+ *		VENDOR_TOKEN_PARAM_ID1 "0x00112233"
+ *		VENDOR_TOKEN_PARAM_ID2 "0x44556677"
+ *		...
+ *	}
+ *
+ *	tuples."word.module2" {
+ *		VENDOR_TOKEN_PARAM_ID1 "0x11223344"
+ *		VENDOR_TOKEN_PARAM_ID2 "0x55667788"
+ *		...
+ *	}
+ *	...
+ * }
+ *
+ *
+ * + *
Mixer Controls
+ * A mixer control is defined as a new section that can include channel mapping, + * TLV data, callback operations and private data. The mixer section also + * includes a few other config options that are shown here :- + * + * 
+ * SectionControlMixer."mixer name" {
+ *	comment "optional comments"
+ *
+ *	index "1"			# Index number
+ *
+ *	channel."name" {		# Channel maps
+ *	   ....
+ *	}
+ *
+ *	ops."ctl" {			# Ops callback functions
+ *	   ....
+ *	}
+ *
+ *	max "32"			# Max control value
+ *	invert "0"			# Whether control values are inverted
+ *
+ *	tlv "tld_data"			# optional TLV data
+ *
+ *	data "pdata for mixer1"		# optional private data
+ * }
+ *
+ * + * The section name is used to define the mixer name. The index number can be + * used to identify topology objects groups(index "0" is common, fit for all + * user cases).This allows driver operations on objects with index number N and + * can be used to add/remove pipelines of objects whilst other objects are + * unaffected. + * + *
Byte Controls
+ * A byte control is defined as a new section that can include channel mapping, + * TLV data, callback operations and private data. The bytes section also + * includes a few other config options that are shown here :- + * + * 
+ * SectionControlBytes."name" {
+ *	comment "optional comments"
+ *
+ *	index "1"			# Index number
+ *
+ *	channel."name" {		# Channel maps
+ *	   ....
+ *	}
+ *
+ *	ops."ctl" {			# Ops callback functions
+ *	   ....
+ *	}
+ *
+ *	base "0"			# Register base
+ *	num_regs "16"			# Number of registers
+ *	mask "0xff"			# Mask
+ *	max "255"			# Maximum value
+ *
+ *	tlv "tld_data"			# optional TLV data
+ *
+ *	data "pdata for mixer1"		# optional private data
+ * }
+ *
+ * + *
Enumerated Controls
+ * A enumerated control is defined as a new section (like mixer and byte) that + * can include channel mapping, callback operations, private data and + * text strings to represent the enumerated control options.
+ * + * The text strings for the enumerated controls are defined in a separate + * section as follows :- + * + * 
+ * SectionText."name" {
+ *
+ *		Values [
+ *			"value1"
+ *			"value2"
+			"value3"
+ *		]
+ * }
+ *
+ * + * All the enumerated text values are listed in the values list.
+ * The enumerated control is similar to the other controls and defined as + * follows :- + * + * 
+ * SectionControlMixer."name" {
+ *	comment "optional comments"
+ *
+ *	index "1"			# Index number
+ *
+ *	texts "EQU1"			# Enumerated text items
+ *
+ *	channel."name" {		# Channel maps
+ *	   ....
+ *	}
+ *
+ *	ops."ctl" {			# Ops callback functions
+ *	   ....
+ *	}
+ *
+ *	data "pdata for mixer1"		# optional private data
+ * }
+ *
+ * + *

DAPM Graph

+ * DAPM graphs can easily be defined using the topology file. The format is + * very similar to the DAPM graph kernel format. :- + * + * 
+ * SectionGraph."dsp" {
+ *	index "1"			# Index number
+ *
+ *	lines [
+ *		"sink1, control, source1"
+ *		"sink2, , source2"
+ *	]
+ * }
+ *
+ * + * The lines in the graph are defined as a variable size list of sinks, + * controls and sources. The control name is optional as some graph lines have + * no associated controls. The section name can be used to differentiate the + * graph with other graphs, it's not used by the kernel atm. + * + *

DAPM Widgets

+ * DAPM widgets are similar to controls in that they can include many other + * objects. Widgets can contain private data, mixer controls and enum controls. + * + * The following widget types are supported and match the driver types :- + * + * * input + * * output + * * mux + * * mixer + * * pga + * * out_drv + * * adc + * * dac + * * switch + * * pre + * * post + * * aif_in + * * aif_out + * * dai_in + * * dai_out + * * dai_link + * + * Widgets are defined as follows :- + * + * 
+ * SectionWidget."name" {
+ *
+ *	index "1"			# Index number
+ *
+ *	type "aif_in"			# Widget type - detailed above
+ *	stream_name "name"		# Stream name
+ *
+ *	no_pm "true"			# No PM control bit.
+ *	reg "20"			# PM bit register offset
+ *	shift "0"			# PM bit register shift
+ *	invert "1			# PM bit is inverted
+ *	subseq "8"			# subsequence number
+ *
+ *	event_type "1"			# DAPM widget event type
+ *	event_flags "1"			# DAPM widget event flags
+ *
+ *	mixer "name"			# Optional Mixer Control
+ *	enum "name"			# Optional Enum Control
+ *
+ *	data "name"			# optional private data
+ * }
+ *
+ * + * The section name is the widget name. The mixer and enum fields are mutually + * exclusive and used to include controls into the widget. The index and data + * fields are the same for widgets as they are for controls whilst the other + * fields map on very closely to the driver widget fields. + * + *
Widget Private Data
+ * Widget can have private data. For the format of the private data, please + * refer to section Control Private Data. + * + *

PCM Capabilities

+ * Topology can also define the PCM capabilities of front end or physical DAIs. + * Capabilities can be defined with the following section :- + * + * 
+ * SectionPCMCapabilities."name" {
+ *
+ *	formats "S24_LE,S16_LE"		# Supported formats
+ *	rates "48000"			# Supported rates
+ *	rate_min "48000"		# Max supported sample rate
+ *	rate_max "48000"		# Min supported sample rate
+ *	channels_min "2"		# Min number of channels
+ *	channels_max "2"		# max number of channels
+ * }
+ *
+ * The supported formats use the same naming convention as the driver macros. + * The PCM capabilities name can be referred to and included by PCM and + * physical DAI sections. + * + *

PCM Configurations

+ * PCM runtime configurations can be defined for playback and capture stream + * directions with the following section :- + * + * 
+ * SectionPCMConfig."name" {
+ *
+ *	config."playback" {		# playback config
+ *		format "S16_LE"		# playback format
+ *		rate "48000"		# playback sample rate
+ *		channels "2"		# playback channels
+ *		tdm_slot "0xf"		# playback TDM slot
+ *	}
+ *
+ *	config."capture" {		# capture config
+ *		format "S16_LE"		# capture format
+ *		rate "48000"		# capture sample rate
+ *		channels "2"		# capture channels
+ *		tdm_slot "0xf"		# capture TDM slot
+ *	}
+ * }
+ *
+ * + * The supported formats use the same naming convention as the driver macros. + * The PCM configuration name can be referred to and included by PCM and + * physical link sections. + * + *

PCM (Front-end DAI & DAI link)

+ * PCM sections define the supported capabilities and configurations for + * supported playback and capture streams, names and flags for front end + * DAI & DAI links. Topology kernel driver will use a PCM object to create + * a pair of FE DAI & DAI links. + * + * 
+ * SectionPCM."name" {
+ *
+ *	index "1"			# Index number
+ *
+ *	id "0"				# used for binding to the PCM
+ *
+ *	dai."name of front-end DAI" {
+ *		id "0"		# used for binding to the front-end DAI
+ *	}
+ *
+ *	pcm."playback" {
+ *		capabilities "capabilities1"	# capabilities for playback
+ *
+ *		configs [		# supported configs for playback
+ *			"config1"
+ *			"config2"
+ *		]
+ *	}
+ *
+ *	pcm."capture" {
+ *		capabilities "capabilities2"	# capabilities for capture
+ *
+ *		configs [		# supported configs for capture
+ *			"config1"
+ *			"config2"
+ *			"config3"
+ *		]
+ *	}
+ *
+ *	# Optional boolean flags
+ *	symmetric_rates			"true"
+ *	symmetric_channels		"true"
+ *	symmetric_sample_bits		"false"
+ *
+ *	data "name"			# optional private data
+ * }
+ *
+ * + *

Physical DAI Link Configurations

+ * The runtime configurations of a physical DAI link can be defined by + * SectionLink.
Backend DAI links belong to physical links, and can + * be configured by either SectionLink or SectionBE, with same syntax. + * But SectionBE is deprecated atm since the internal processing is + * actually same. + * + * 
+ * SectionLink."name" {
+ *
+ *	index "1"			# Index number
+ *
+ *	id "0"				# used for binding to the link
+ *
+ *	stream_name "name"		# used for binding to the link
+ *
+ *	hw_configs [	# runtime supported HW configurations, optional
+ *		"config1"
+ *		"config2"
+ *		...
+ *	]
+ *
+ *	default_hw_conf_id "1"		#default HW config ID for init
+ *
+ *	# Optional boolean flags
+ *	symmetric_rates			"true"
+ *	symmetric_channels		"false"
+ *	symmetric_sample_bits		"true"
+ *
+ *	data "name"			# optional private data
+ * }
+ *
+ * + * A physical link can refer to multiple runtime supported hardware + * configurations, which is defined by SectionHWConfig. + * + * 
+ * SectionHWConfig."name" {
+ *
+ *	id "1"				# used for binding to the config
+ *	format "I2S"			# physical audio format.
+ *	bclk   "master"			# Platform is master of bit clock
+ *	fsync  "slave"			# Platform is slave of fsync
+ * }
+ *
+ * + *

Physical DAI

+ * A physical DAI (e.g. backend DAI for DPCM) is defined as a new section + * that can include a unique ID, playback and capture stream capabilities, + * optional flags, and private data.
+ * Its PCM stream capablities are same as those for PCM objects, + * please refer to section 'PCM Capabilities'. + * + * 
+ * SectionDAI."name" {
+ *
+ *	index "1"			# Index number
+ *
+ *	id "0"				# used for binding to the Backend DAI
+ *
+ *	pcm."playback" {
+ *		capabilities "capabilities1"	# capabilities for playback
+ *	}
+ *
+ *	pcm."capture" {
+ *		capabilities "capabilities2"	# capabilities for capture
+ *	}
+ *
+ *	symmetric_rates "true"			# optional flags
+ *	symmetric_channels "true"
+ *	symmetric_sample_bits "false"
+ *
+ *	data "name"			# optional private data
+ * }
+ *
+ * + *

Manifest Private Data

+ * Manfiest may have private data. Users need to define a manifest section + * and add the references to 1 or multiple data sections. Please refer to + * section 'How to define an element with private data'.
+ * And the text conf file can have at most 1 manifest section.

+ * + * Manifest section is defined as follows :- + * + * 
+ * SectionManifest"name" {
+ *
+ *	data "name"			# optional private data
+ * }
+ *
+ * + *

Include other files

+ * Users may include other files in a text conf file via alsaconf syntax + * . This allows users to define common info + * in separate files (e.g. vendor tokens, tuples) and share them for + * different platforms, thus save the total size of config files.
+ * Users can also specifiy additional configuraiton directories relative + * to "/usr/share/alsa/" to search the included files, via alsaconf syntax + * .

+ * + * For example, file A and file B are two text conf files for platform X, + * they will be installed to /usr/share/alsa/topology/platformx. If we + * need file A to include file B, in file A we can add:
+ * + *
+ *

+ * + * ALSA conf will search and open an included file in the following order + * of priority: + * 1. directly open the file by its name; + * 2. search for the file name in "/usr/share/alsa"; + * 3. search for the file name in user specified subdirectories under + * "/usr/share/alsa". + * + * The order of the included files need not to be same as their + * dependencies, since the topology library will load them all before + * parsing their dependencies.
+ * + * The configuration directories defined by a file will only be used to search + * the files included by this file. + */ + +/** Maximum number of channels supported in one control */ +#define SND_TPLG_MAX_CHAN 8 + +/** Topology context */ +typedef struct snd_tplg snd_tplg_t;
