  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.
  52  *
  53  * Obtaining the system ACPI tables is an OS-specific operation.
  54  *
  55  * This utility can be ported to any host operating system by providing a
  56  * module containing system-specific versions of these interfaces:
  57  *
  58  *      AcpiOsGetTableByAddress
  59  *      AcpiOsGetTableByIndex
  60  *      AcpiOsGetTableByName
  61  *
  62  * See the ACPICA Reference Guide for the exact definitions of these
  63  * interfaces. Also, see these ACPICA source code modules for example
  64  * implementations:
  65  *
  66  *      source/os_specific/service_layers/oswintbl.c
  67  *      source/os_specific/service_layers/oslinuxtbl.c
