hi all:
then the acobject.h in acpica different from the kernel,
"ACPI_OBJECT_COMMON_HEADER" and "u8" not in the same line .
in the acpica this file
typedef struct acpi_object_common
{
ACPI_OBJECT_COMMON_HEADER
} ACPI_OBJECT_COMMON;
typedef struct acpi_object_integer
{
ACPI_OBJECT_COMMON_HEADER
UINT8 Fill[3]; /* Prevent warning on some compilers */
UINT64 Value;
} ACPI_OBJECT_INTEGER;
and in kenel this file
/drivers/acpi/acpica/acobject.h,"ACPI_OBJECT_COMMON_HEADER" and "u8" in
the same line ,cause confusion.
struct acpi_object_common {
ACPI_OBJECT_COMMON_HEADER};
struct acpi_object_integer {
ACPI_OBJECT_COMMON_HEADER u8 fill[3]; /* Prevent warning on some
compilers */
u64 value;
};
others just so.
