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
turbostat - gather performance statistics
SYNOPSIS
acpidump [options]
acpixtract [options] [filename]
turbostat [options] [command [arg]...]
madt
DESCRIPTION
This manual page documents briefly the acpidump , acpixtract ,
turbostat and madt commands. acpidump and acpixtract options are
described below while madt can only read an APIC table from standard
input.
turbostat reads hardware registers and gather statistics on the
processor clock frequency and C-state usage. Works properly on Nehalem
and newer processors and on Linux kernel 2.6.30 and later versions.
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>
OPTIONS
turbostat options are as follow:
-v makes turbostat more verbose
-i <sec>
polling interval, default is 5
When given a command turbostat runs it and outputs statistics gathered
while the program was running.
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
