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):
