IASL(8) BSD System Manager's Manual IASL(8) NAME
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

ACPIDUMP(8) BSD System Manager's Manual ACPIDUMP(8) NAME
acpidump -- dump ACPI tables and ASL SYNOPSIS
acpidump [-d] [-t] [-h] [-v] [-f dsdt_input] [-o dsdt_output] DESCRIPTION
The acpidump utility analyzes ACPI tables in physical memory and can dump them to a file. In addition, acpidump can call iasl(8) to disas- semble AML (ACPI Machine Language) found in these tables and dump them as ASL (ACPI Source Language) to stdout. ACPI tables have an essential data block (the DSDT, Differentiated System Description Table) that includes information used on the kernel side such as detailed information about PnP hardware, procedures for controlling power management support, and so on. The acpidump utility can extract the DSDT data block from physical memory and store it into an output file and optionally also disassemble it. If any Secondary System Description Table (SSDT) entries exist, they will also be included in the output file and disassembly. When acpidump is invoked without the -f option, it will read ACPI tables from physical memory via /dev/mem. First it searches for the RSDP (Root System Description Pointer), which has the signature "RSD PTR ", and then gets the RSDT (Root System Description Table), which includes a list of pointers to physical memory addresses for other tables. The RSDT itself and all other tables linked from RSDT are generically called SDTs (System Description Tables) and their header has a common format which consists of items such as Signature, Length, Revision, Checksum, OEMID, OEM Table ID, OEM Revision, Creator ID and Creator Revision. When invoked with the -t flag, the acpidump utility dumps con- tents of the following tables: DMAR DSDT ECDT FACS FADT HPET MADT MCFG RSD PTR RSDT The RSDT contains a pointer to the physical memory address of the FACP (Fixed ACPI Description Table). The FACP defines static system infor- mation about power management support (ACPI Hardware Register Implementation) such as interrupt mode (INT_MODEL), SCI interrupt number, SMI command port (SMI_CMD) and the location of ACPI registers. The FACP also has a pointer to a physical memory address for the DSDT. While the other tables are fixed format, the DSDT consists of free-formatted AML data. OPTIONS
The following options are supported by acpidump: -d Disassemble the DSDT into ASL using iasl(8) and print the results to stdout. -t Dump the contents of the various fixed tables listed above. -h Displays usage and exit. -v Enable verbose messages. -f dsdt_input Load the DSDT from the specified file instead of physical memory. Since only the DSDT is stored in the file, the -t flag may not be used with this option. -o dsdt_output Store the DSDT data block from physical memory into the specified file. FILES
/dev/mem EXAMPLES
If a developer requests a copy of your ASL, please use the following command to dump all tables and compress the result. # acpidump -dt | gzip -c9 > my_computer.asl.gz This example dumps the DSDT from physical memory to foo.dsdt. It also prints the contents of various system tables and disassembles the AML contained in the DSDT to stdout, redirecting the output to foo.asl. # acpidump -t -d -o foo.dsdt > foo.asl This example reads a DSDT file and disassembles it to stdout. Verbose messages are enabled. # acpidump -v -d -f foo.dsdt SEE ALSO
