+ * How to add a new table:
+ *
+ * - Add the C table definition to the actbl1.h or actbl2.h header.
+ * - Add ACPI_xxxx_OFFSET macro(s) for the table (and subtables) to list below.
+ * - Define the table in this file (for the disassembler). If any
+ *   new data types are required (ACPI_DMT_*), see below.
+ * - Add an external declaration for the new table definition (AcpiDmTableInfo*)
+ *     in acdisam.h
+ * - Add new table definition to the dispatch table in dmtable.c (AcpiDmTableData)
+ *     If a simple table (with no subtables), no disassembly code is needed.
+ *     Otherwise, create the AcpiDmDump* function for to disassemble the table
+ *     and add it to the dmtbdump.c file.
+ * - Add an external declaration for the new AcpiDmDump* function in acdisasm.h
+ * - Add the new AcpiDmDump* function to the dispatch table in dmtable.c
+ * - Create a template for the new table
+ * - Add data table compiler support
+ *
+ * How to add a new data type (ACPI_DMT_*):
+ *
+ * - Add new type at the end of the ACPI_DMT list in acdisasm.h
+ * - Add length and implementation cases in dmtable.c  (disassembler)
+ * - Add type and length cases in dtutils.c (DT compiler)

+ *                     discarding upper 3 bits because they are always 0.
+ *                  4) Compressed code = concatenate 0 and the 3 5-bit values
+ *
+ *              The format of the compressed product identifier is as follows:
+ *              Byte 0: Bit 7       - Reserved (0)
+ *                      Bits 6-2:   - 1st character of compressed mfg code

+Instructions for integrating iASL compiler into MS VC++ 6.0 environment.
+
+Part 1.  Integration as a custom tool
+
+This procedure adds the iASL compiler as a custom tool that can be used
+to compile ASL source files.  The output is sent to the VC output 
+window.
+
+a) Select Tools->Customize.
+
+b) Select the "Tools" tab.
+
+c) Scroll down to the bottom of the "Menu Contents" window.  There you
+   will see an empty rectangle.  Click in the rectangle to enter a 
+   name for this tool.
+
+d) Type "iASL Compiler" in the box and hit enter.  You can now edit
+   the other fields for this new custom tool.
+
+e) Enter the following into the fields:
+
+   Command:             C:\Acpi\iasl.exe
+   Arguments:           -e "$(FilePath)"
+   Initial Directory    "$(FileDir)"
+   Use Output Window    <Check this option>
+
+   "Command" must be the path to wherever you copied the compiler.
+   "-e" instructs the compiler to produce messages appropriate for VC.
+   Quotes around FilePath and FileDir enable spaces in filenames.
+
+f) Select "Close".
+
+These steps will add the compiler to the tools menu as a custom tool.
+By enabling "Use Output Window", you can click on error messages in
+the output window and the source file and source line will be
+automatically displayed by VC.  Also, you can use F4 to step through
+the messages and the corresponding source line(s).
+
+
+Part 2.  Integration into a project build
+
+This procedure creates a project that compiles ASL files to AML.
+
+a) Create a new, empty project and add your .ASL files to the project
+
+b) For all ASL files in the project, specify a custom build (under
+Project/Settings/CustomBuild with the following settings (or similar):
+
+Commands:
+c:\acpi\libraries\iasl.exe -vs -vi "$(InputPath)"
+
+Output:
+$(InputDir)\$(InputPath).aml
+
+
+
+Compiler Generation From Source
+
+Generation of the ASL compiler from source code requires these items:
+
+
+Required Tools
+1) The Flex (or Lex) lexical analyzer generator.
+2) The Bison (or Yacc) parser generator.
+3) An ANSI C compiler.
+
+
+Required Source Code.
+
+There are three major source code components that are required to 
+generate the compiler:
+
+1) The ASL compiler source.
+2) The ACPI CA Core Subsystem source.  In particular, the Namespace Manager
+     component is used to create an internal ACPI namespace and symbol table,
+     and the AML Interpreter is used to evaluate constant expressions.
+3) The Common source for all ACPI components.

+ * Note: History of _PRW support in ACPICA
+ *
+ * Originally (2000 - 2010), the GPE initialization code performed a walk of
+ * the entire namespace to execute the _PRW methods and detect all GPEs
+ * capable of waking the system.
+ *
+ * As of 10/2010, the _PRW method execution has been removed since it is
+ * actually unnecessary. The host OS must in fact execute all _PRW methods
+ * in order to identify the device/power-resource dependencies. We now put
+ * the onus on the host OS to identify the wake GPEs as part of this process
+ * and to inform ACPICA of these GPEs via the AcpiSetupGpeForWake interface. This
+ * not only reduces the complexity of the ACPICA initialization code, but in
+ * some cases (on systems with very large namespaces) it should reduce the
+ * kernel boot time as well.

+ * Naming convention for AML interpreter execution routines.
+ *
+ * The routines that begin execution of AML opcodes are named with a common
+ * convention based upon the number of arguments, the number of target operands,
+ * and whether or not a value is returned:
+ *
+ *      AcpiExOpcode_xA_yT_zR
+ *
+ * Where:
+ *
+ * xA - ARGUMENTS:    The number of arguments (input operands) that are
+ *                    required for this opcode type (0 through 6 args).
+ * yT - TARGETS:      The number of targets (output operands) that are required
+ *                    for this opcode type (0, 1, or 2 targets).
+ * zR - RETURN VALUE: Indicates whether this opcode type returns a value
+ *                    as the function return (0 or 1).
+ *
+ * The AcpiExOpcode* functions are called via the Dispatcher component with
+ * fully resolved operands.

+ * and whether or not a value is returned:
+ *
+ *      AcpiExOpcode_xA_yT_zR
+ *
+ * Where:
+ *
+ * xA - ARGUMENTS:    The number of arguments (input operands) that are
+ *                    required for this opcode type (1 through 6 args).
+ * yT - TARGETS:      The number of targets (output operands) that are required
+ *                    for this opcode type (0, 1, or 2 targets).
+ * zR - RETURN VALUE: Indicates whether this opcode type returns a value
+ *                    as the function return (0 or 1).
+ *
+ * The AcpiExOpcode* functions are called via the Dispatcher component with
+ * fully resolved operands.

+ * The routines that begin execution of AML opcodes are named with a common
+ * convention based upon the number of arguments, the number of target operands,
+ * and whether or not a value is returned:
+ *
+ *      AcpiExOpcode_xA_yT_zR
+ *
+ * Where:
+ *
+ * xA - ARGUMENTS:    The number of arguments (input operands) that are
+ *                    required for this opcode type (1 through 6 args).
+ * yT - TARGETS:      The number of targets (output operands) that are required
+ *                    for this opcode type (0, 1, or 2 targets).
+ * zR - RETURN VALUE: Indicates whether this opcode type returns a value
+ *                    as the function return (0 or 1).
+ *
+ * The AcpiExOpcode* functions are called via the Dispatcher component with
+ * fully resolved operands.

+ * DESCRIPTION: This function derives a full PCI ID for a PCI device,
+ *              consisting of a Segment number, Bus number, Device number,
+ *              and function code.
+ *
+ *              The PCI hardware dynamically configures PCI bus numbers
+ *              depending on the bus topology discovered during system
+ *              initialization. This function is invoked during configuration
+ *              of a PCI_Config Operation Region in order to (possibly) update
+ *              the Bus/Device/Function numbers in the PciId with the actual
+ *              values as determined by the hardware and operating system
+ *              configuration.
+ *
+ *              The PciId parameter is initially populated during the Operation
+ *              Region initialization. This function is then called, and is
+ *              will make any necessary modifications to the Bus, Device, or
+ *              Function number PCI ID subfields as appropriate for the
+ *              current hardware and OS configuration.
+ *
+ * NOTE:        Created 08/2010. Replaces the previous OSL AcpiOsDerivePciId
+ *              interface since this feature is OS-independent. This module
+ *              specifically avoids any use of recursion by building a local
+ *              temporary device list.

+ * at the time they are evaluated (via AcpiEvaluateObject). The purpose of this
+ * validation is to detect problems with BIOS-exposed predefined ACPI objects
+ * before the results are returned to the ACPI-related drivers.
+ *
+ * There are several areas that are validated:
+ *
+ *  1) The number of input arguments as defined by the method/object in the
+ *      ASL is validated against the ACPI specification.
+ *  2) The type of the return object (if any) is validated against the ACPI
+ *      specification.
+ *  3) For returned package objects, the count of package elements is
+ *      validated, as well as the type of each package element. Nested
+ *      packages are supported.
+ *
+ * For any problems found, a warning message is issued.

+ * This module attempts to repair or convert objects returned by the

+ * specification. The need for this code is dictated by the many machines that
+ * return incorrect types for the standard predefined methods. Performing these
+ * conversions here, in one place, eliminates the need for individual ACPI
+ * device drivers to do the same. Note: Most of these conversions are different
+ * than the internal object conversion routines used for implicit object
+ * conversion.
+ *
+ * The following conversions can be performed as necessary:
+ *
+ * Integer -> String
+ * Integer -> Buffer
+ * String  -> Integer
+ * String  -> Buffer
+ * Buffer  -> Integer
+ * Buffer  -> String
+ * Buffer  -> Package of Integers
+ * Package -> Package of one Package
+ *
+ * Additional possible repairs:
+ *
+ * Required package elements that are NULL replaced by Integer/String/Buffer
+ * Incorrect standalone package wrapped with required outer package

+ *
+ *      Note: CPU execution analysis has shown that the AML interpreter spends

+ *
+ *              The point of this procedure is to provide a generic namespace
+ *              walk routine that can be called from multiple places to
+ *              provide multiple services; the callback function(s) can be

+ *              pointer structure.  If it is found, set *RSDP to point to it.
+ *
+ * NOTE1:       The RSDP must be either in the first 1K of the Extended
+ *              BIOS Data Area or between E0000 and FFFFF (From ACPI Spec.)
+ *              Only a 32-bit physical address is necessary.
+ *
+ * NOTE2:       This function is always available, regardless of the
+ *              initialization state of the rest of ACPI.

+ * Architecture-specific ACPICA Subsystem Data Types
+ *
+ * The goal of these types is to provide source code portability across
+ * 16-bit, 32-bit, and 64-bit targets.
+ *
+ * 1) The following types are of fixed size for all targets (16/32/64):
+ *
+ * BOOLEAN      Logical boolean
+ *
+ * UINT8        8-bit  (1 byte) unsigned value
+ * UINT16       16-bit (2 byte) unsigned value
+ * UINT32       32-bit (4 byte) unsigned value
+ * UINT64       64-bit (8 byte) unsigned value
+ *
+ * INT16        16-bit (2 byte) signed value
+ * INT32        32-bit (4 byte) signed value
+ * INT64        64-bit (8 byte) signed value
+ *
+ * COMPILER_DEPENDENT_UINT64/INT64 - These types are defined in the
+ * compiler-dependent header(s) and were introduced because there is no common
+ * 64-bit integer type across the various compilation models, as shown in
+ * the table below.
+ *
+ * Datatype  LP64 ILP64 LLP64 ILP32 LP32 16bit
+ * char      8    8     8     8     8    8
+ * short     16   16    16    16    16   16
+ * _int32         32
+ * int       32   64    32    32    16   16
+ * long      64   64    32    32    32   32
+ * long long            64    64
+ * pointer   64   64    64    32    32   32
+ *
+ * Note: ILP64 and LP32 are currently not supported.
+ *
+ *
+ * 2) These types represent the native word size of the target mode of the
+ * processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
+ * usually used for memory allocation, efficient loop counters, and array
+ * indexes. The types are similar to the size_t type in the C library and are
+ * required because there is no C type that consistently represents the native
+ * data width. ACPI_SIZE is needed because there is no guarantee that a
+ * kernel-level C library is present.
+ *
+ * ACPI_SIZE        16/32/64-bit unsigned value
+ * ACPI_NATIVE_INT  16/32/64-bit signed value
