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 SEE ALSO

iasl -- Intel ASL compiler and disassembler (iASL) SYNOPSIS
iasl [options] <input file> DESCRIPTION
The iasl is a fully-featured compiler for the ACPI Source Language (ASL). It translates ASL to ACPI Machine Language (AML), but iasl can also act as a disassembler, translating AML to ASL. OPTIONS
Global -@ file Specify command file. -I dir Specify additional include directory. General Output -p prefix Specify a path or filename prefix for all output files. -va Disable all errors and warnings in the summary. -vi Use less verbose errors and warnings. -vo Enable optimization comments. -vr Disable remarks. -vs Disable signon. -w 1 | 2 | 3 Set warning reporting level. AML Output Files -s a | c Create AML in assembler (*.asm) or C (*.c) source file. -i a | c Create assembler (*.inc) or C (*.h) include file. -t a | c Create AML in assembler or C hex table (*.hex). AML Code Generation -oa Disable all optimizations (compatibility mode). -of Disable constant folding. -oi Disable integer optimization to operation codes. -on Disable named reference string optimization. -r revision Override table header revision (1-255). Listings -l Create mixed, ASL and AML, listing file (*.lst). -ln Create namespace file (*.nsp). -ls Create combined source file (*.src). AML Disassembler -d file Disassemble binary ACPI table to a file (*.dsl). -dc file Disassemble AML and immediately compile it. -e f1, f2 Include ACPI table(s) for external symbol resolution. -2 Emit ACPI 2.0 compatible ASL code. -g Get ACPI tables and write to files (*.dat). Help -h Display additional help and compiler debug options. -hc Display operators allowed in constant expressions. -hr Display ACPI reserved method names. SEE ALSO
