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
