aml_osi_implementation()

aml_object_t * aml_osi_implementation	(	aml_method_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.

Todo:

Implement _OSI strings properly. For now, we just return true for everything.

Implementation of the _REV predefined method.

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

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.

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.
