Detailed Description

Encoding of an AML object.

Every AML object has a specific encoding. This encoding information is used to parse AML objects. A table of AML_BYTE_ENCODING entries allows to parse an AML bytestream. This structure is also used to describe field objects.

Cf. ACPI 6.3 specification, s20.2.

Field Documentation

◆ Attribute

AML_OP_ATTRIBUTE _AML_BYTE_ENCODING::Attribute

Additional information on the AML object.

Definition at line 145 of file Aml.h.

◆ Format [1/2]

AML_OP_PARSE_FORMAT _AML_BYTE_ENCODING::Format[6]

Definition at line 133 of file AcpiSdt.h.

◆ Format [2/2]

AML_PARSE_FORMAT _AML_BYTE_ENCODING::Format[EAmlParseIndexMax]

Type of each fixed argument.

Definition at line 142 of file Aml.h.

◆ MaxIndex [1/2]

EAML_PARSE_INDEX _AML_BYTE_ENCODING::MaxIndex

Number of fixed arguments for the AML statement represented by the OpCode & SubOpcode. Maximum is 6 for AML objects. Maximum is 3 for field objects.

Definition at line 134 of file Aml.h.

◆ MaxIndex [2/2]

AML_OP_PARSE_INDEX _AML_BYTE_ENCODING::MaxIndex

Definition at line 132 of file AcpiSdt.h.

◆ NameIndex

EAML_PARSE_INDEX _AML_BYTE_ENCODING::NameIndex

If the encoding has the AML_IN_NAMESPACE attribute (cf Attribute field below), indicate where to find the name in the fixed list of arguments.

Definition at line 139 of file Aml.h.

◆ OpCode

UINT8 _AML_BYTE_ENCODING::OpCode

OpCode of the AML object.

Definition at line 122 of file Aml.h.

◆ Str

CONST CHAR8* _AML_BYTE_ENCODING::Str

String field allowing to print the AML object.

Definition at line 118 of file Aml.h.

◆ SubOpCode

UINT8 _AML_BYTE_ENCODING::SubOpCode

SubOpCode of the AML object. The SubOpcode field has a valid value when the OpCode is 0x5B, otherwise this field must be zero. For field objects, the SubOpCode is not used.
