50 * acpidump - A portable utility for obtaining system ACPI tables and dumping
51 * them in an ASCII hex format suitable for binary extraction via acpixtract.
53 * Obtaining the system ACPI tables is an OS-specific operation.
55 * This utility can be ported to any host operating system by providing a
56 * module containing system-specific versions of these interfaces:
58 * AcpiOsGetTableByAddress
59 * AcpiOsGetTableByIndex
60 * AcpiOsGetTableByName
62 * See the ACPICA Reference Guide for the exact definitions of these
63 * interfaces. Also, see these ACPICA source code modules for example
66 * source/os_specific/service_layers/oswintbl.c
67 * source/os_specific/service_layers/oslinuxtbl.c
