aml_gl_get()

aml_mutex_obj_t * aml_gl_get

(

aml_os_implementation()

aml_object_t * aml_os_implementation	(	aml_method_obj_t *	method,
		aml_object_t **	args,
		uint64_t	argCount
	)

Implementation of the _OS predefined method.

The _OS method evaluates to a string that identifies the operating system.

Parameters

method	The _OS method object.
args	The arguments passed to the method.
argCount	The number of arguments passed to the method.

Returns

On success, the return value of the method. On failure, ERR and errno is set.

aml_osi_implementation()

aml_object_t * aml_osi_implementation	(	aml_method_obj_t *	method,
		aml_object_t **	args,
		uint64_t	argCount
	)

Implementation of the _OSI predefined method.

The _OSI method is used by the ACPI firmware to query the operating system's capabilities. But for now we just return true for everything.

@See section 5.7.2 of the ACPI specification.

Parameters

method	The _OSI method object.
args	The arguments passed to the method.
argCount	The number of arguments passed to the method.

Returns

On success, the return value of the method. On failure, ERR and errno is set.

aml_predefined_init()

uint64_t aml_predefined_init

(

void

)

Initialize predefined AML names and objects.

Returns

On success, 0. On failure, ERR and errno is set.

aml_object_t * aml_rev_implementation	(	aml_method_obj_t *	method,
		aml_object_t **	args,
		uint64_t	argCount
	)

Implementation of the _REV predefined method.

The _REV method returns the the revision of the ACPI Specification implemented by the OS.

ACPI_REVISION

Parameters

method	The _REV method object.
args	The arguments passed to the method.
argCount	The number of arguments passed to the method.

Returns

On success, the return value of the method. On failure, ERR and errno is set.
