157 * acpidump - A portable utility for obtaining system ACPI tables and dumping
158 * them in an ASCII hex format suitable for binary extraction via acpixtract.
159 *
160 * Obtaining the system ACPI tables is an OS-specific operation.
161 *
162 * This utility can be ported to any host operating system by providing a
163 * module containing system-specific versions of these interfaces:
164 *
165 * AcpiOsGetTableByAddress
166 * AcpiOsGetTableByIndex
167 * AcpiOsGetTableByName
168 *
169 * See the ACPICA Reference Guide for the exact definitions of these
170 * interfaces. Also, see these ACPICA source code modules for example
171 * implementations:
172 *
173 * source/os_specific/service_layers/oswintbl.c
