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