ACPIDUMP(1)                                                   General Commands Manual                                                  ACPIDUMP(1)

NAME

       acpidump - dump a system's ACPI tables to an ASCII file
       acpixtract - convert ASCII acpidump output to raw binary table
       turbostat - gather performance statistics

SYNOPSIS

       acpidump [options]
       acpixtract [options] [filename]
       turbostat [options] [command [arg]...]

DESCRIPTION

       This manual page documents briefly the acpidump , acpixtract and turbostat commands.

       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 stdout 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

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
