Acpi table dump utility
This manual page briefly documents the acpidump command. The option list is taken from the interactive help.
The acpidump command extracts the ACPI tables currently in use from the running kernel in a form usable for later processing by the acpixtract command.
Invocation of acpidump without parameters will dump all available ACPI tables. Multiple mixed instances of the -a , -f , and -n parameters can be used.
Dump tables in binary format (versus the default human-readable form)
