NAME

acpidump − dump a system’s ACPI tables to an ASCII file
acpixtract − convert ASCII acpidump output to raw binary table
madt − parser for APIC table

SYNOPSIS

acpidump [options]
acpixtract
[options] [filename]
madt

DESCRIPTION

This manual page documents briefly the acpidump , acpixtract and madt commands. acpidump and acpixtract options are described below while madt can only read an APIC table from standard input.

OPTIONS

acpidump options are as follow:
−a, −−addr 0x1234

look for tables at this phisical address

−t, −−table DSDT

only dump table with DSDT signature

−o, −−output filename

redirect output from stdin to filename

−b, −−binary

dump data in binary form rather than in hex−dump format

−l, −−lenght 0x456

works only with −−addr, dump phisical memory region without trying to understand it’s contents

−s, −−skip 2

skip 2 tables of the given name and output only 3rd one

−h, −−help

outputs an help message

acpixtract only option is:
−n instance_number

prints Nth instance of target table, default is 1

OPTIONS

acpixtract options are as follow:

−a

extract all tables, not just DSDT/SSDT

−l

list table summaries, do not extract

−s<Signature>

Extract all tables named <Signature>

EXAMPLES

Dump the DSDT table to the file DSDT.aml in binary format (this can be disassembled later with iasl(1):

acpidump −b −t DSDT −o DSDT.aml

Show the FACP table:

acpidump −t FACP > FACP.dat
acpixtract −a FACP.dat
iasl −d FACP.dat

Dump and extract all ACPI tables:

acpidump −o DSDT.dat
acpixtract −a

Parse APIC tables:

acpidump −o DSDT.dat
acpixtract −sAPIC DSDT.dat
madt < APIC.dat
