ACPIDUMP(8) System Manager's Manual ACPIDUMP(8)

NAME

acpidumpdump ACPI tables

SYNOPSIS

acpidump -o prefix

DESCRIPTION

The acpidump command stores ACPI tables from physical memory into files specified by prefix. If prefix specifies a directory, the generated files will be of the form <prefix>/<sig>.<id>. Otherwise, they will be named <prefix>.<sig>.<id>. “sig” is the signature of the ACPI Table; “id” is unique for each table.
Additionally a file called <prefix>/headers or <prefix>.headers will be created that contains additional human readable information pertaining to this specific dump.
The ACPICA disassembler is available through the OpenBSD ports tree or package system:
# pkg_add acpica 
$ iasl -d <prefix>.<sig>.<id>
acpidump requires the ability to open /dev/kmem which may be restricted based upon the value of the kern.allowkmem sysctl(8).
