# acpidump(1)

ACPI table dump utility

## NAME

acpidump - ACPI table dump utility

## SYNOPSIS

**acpidump** \[*\<option\>*...*\]*

## DESCRIPTION

This manual page briefly documents the **acpidump** command.  The option list is taken from the interactive help.

The **acpidump** command extracts the ACPI tables currently in use from the running kernel in a form usable for later processing by the **acpixtract** command.

Invocation of **acpidump** without parameters will dump all available ACPI tables.  Multiple mixed instances of the **-a** , **-f** , and **-n** parameters can be used.

## OPTIONS

- **-b**

  Dump tables in binary format (versus the default human-readable form)

- **-h \| -?**

  Display this help message

- **-o \<file\>**

  Redirect output to a file.  This file can be used later by **acpixtract** to examine the contents of the ACPI tables.

- **-s**

  Print table summaries only.

- **-v**

  Print the version of this utility.

- **-z**

  Verbose mode.

- **-a \<address\>**

  Get a table from a physical address (must be superuser and you must be careful which address you use -- dmesg will typically report the addresses for the various tables).

- **-f \<binary-file\>**

  Get a table from a binary file (see the **-b** option).

- **-n \<signature\>**

  Get a table via it's name or signature (e.g., MADT or SSDT).
