Detailed Description

Integer revision handling.

This module handles the varying size of integers in AML, which can be either 32 or 64 bits depending on the ACPI revision.

Macros
#define	AML_TRUE   aml_integer_ones()
	AML Boolean true value.
#define	AML_FALSE   0
	AML Boolean false value.

Typedefs
typedef uint64_t	aml_uint_t
	AML Integer type.

Functions
uint64_t	aml_integer_handling_init (void)
	Initialize integer handling.
uint8_t	aml_integer_byte_size (void) PURE
	Get the byte size of an AML integer.
uint8_t	aml_integer_bit_size (void) PURE
	Get the bit size of an AML integer.
aml_uint_t	aml_integer_ones (void) PURE
	Get a mask with all bits set for the current AML integer size.
