acpidumpdump ACPI tables

acpidump -o prefix_for_output

The acpidump command stores ACPI tables from physical memory into files specified by prefix_for_output. The files generated will be of the form <prefix>.<sig>.<id>. “sig” is the signature of the ACPI Table; “id” is unique for each table.

Additionally a file called <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>

/dev/mem
 

pkg_add(1), mem(4), packages(7), ports(7)

The acpidump command first appeared in OpenBSD 3.8.
