Power management tools
----------------------
This is a small collection of power management test and
investigation tools. See http://lesswatts.org/projects/acpi/
for more information on ACPI for Linux.
.turbostat/turbostat
--------------------
see comments in turbostat.c source file
./acpidump/acpidump
-------------------
This utility dumps a system's ACPI tables to an ASCII file.
Typically it is used to dump all the ACPI tables
to attach to a bug report for later examination:
# ./acpidump > acpidump.out
./acpidump/acpixtract
--------------------
Convert ASCII acpidump output to raw binary tables:
$ acpixtract/acpixtract -a acpidump.out
Acpi table [DSDT] - 15974 bytes written to DSDT.dat
Acpi table [FACS] - 64 bytes written to FACS.dat
Acpi table [FACP] - 116 bytes written to FACP.dat
Acpi table [APIC] - 120 bytes written to APIC.dat
Acpi table [WDDT] - 64 bytes written to WDDT.dat
Acpi table [MCFG] - 60 bytes written to MCFG.dat
Acpi table [ASF!] - 166 bytes written to ASF!.dat
Acpi table [SSDT] - 444 bytes written to SSDT1.dat
Acpi table [SSDT] - 439 bytes written to SSDT2.dat
Acpi table [SSDT] - 439 bytes written to SSDT3.dat
Acpi table [SSDT] - 439 bytes written to SSDT4.dat
Acpi table [SSDT] - 439 bytes written to SSDT5.dat
Acpi table [RSDT] - 76 bytes written to RSDT.dat
Acpi table [RSDP] - 20 bytes written to RSDP.dat
Disassembler
------------
Convert binary table into human readable form
iasl can be downloaded from Intel:
http://www.intel.com/technology/IAPC/acpi/downloads.htm
Which creates DSDT.dsl this way:
$ iasl -a *.dat
...
creates *.dsl
pmtest -- does not work
------
This utility can be used by Linux kernel developers to test
power management support in their drivers. It consists of
an installable kernel module and a Perl script to drive
the module.
Example: pmtest -d3 VGA
Change Log
----------
20100123
add turbostat program
acpixtract: change %6d printf conversion string %6zd
tweak this README
20070511
delete acpitbl script
it is obsoleted by iasl -d
