- Using the ACPI debugger with kdb
- --------------------------------
- ACPI CA includes a full-featured debugger, which allows the examination of
- a running system's ACPI tables, as well as running and stepping through
- control methods.
- Configuration
- -------------
- 1) Edit the main acpi Makefile. On the ACPI_CFLAGS line, remove the '#', thus
- enabling the debugger.
- 2) Download the latest kdb patch from:
- ftp://oss.sgi.com/www/projects/kdb/download/ix86/
- Follow the instructions at http://oss.sgi.com/projects/kdb/ on how to
- install the patch and configure KDB.
- 3) This would probably be a good time to recompile the kernel, and make sure
- kdb works (Hitting the Pause key should drop you into it. Type "go" to exit
- it.
- 4) The kdb <--> ACPI debugger interface is a module. Type "make modules", and
- it will be built and placed in drivers/acpi/kdb.
- 5) Change to that directory and type "insmod kdbm_acpi.o". This loads the
- module we just built.
- 6) Break back into kdb. If you type help, you should now see "acpi" listed as
- a command, at the bottom.
- 7) Type "acpi". You are now in the ACPI debugger. While hosted by kdb, it is
- wholly separate, and has many ACPI-specific commands. Type "?" or "help"
- to get a listing of the command categories, and then "help <category>" for
- a list of commands and their descriptions
