.Sh NAME
.Nm acpixtract
.Nd extract binary ACPI tables from a dump file
.Sh SYNOPSIS
.Nm
.Op Fl ahlmv
.Op Fl s Ar signature
.Ar file
.Sh DESCRIPTION
The
.Nm
utility extracts the binary data from a dump of the system's Advanced
Configuration and Power Interface (ACPI) tables.
The dump is usually obtained via the
.Xr acpidump 8
command.
The resulting binary file(s) are represented in the ACPI
.Sy ASL
assembly language.
For each table extracted, a corresponding
.Em table.dat
file will be created.
.Sh OPTIONS
The following options are supported:
.Bl -tag -width Ds
.It Fl a
Extract all of the tables found.
By default only the
.Sy DSDT
and
.Sy SSDT
tables will be extracted.
.It Fl h
Display the usage message and exit.
.It Fl l
List tables only, do not extract.
.It Fl m
Make a single file for all of the
.Sy DSDT
and
.Sy SSDT
tables.
.It Fl s Ar signature
Get the table with the specified signature.
.It Fl v
Print the version.
.El
.Sh EXAMPLES
.Sy Example 1
Extract all ACPI tables
.Pp
The following example extracts all of the individual ACPI tables from a
previously created dump of the ACPI tables from a running system.
Such a dump can be created with the
.Xr acpidump 8
utility.
Extracted tables can then be inspected or disassembled by the
iasl utility on any platform.
