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