acpihelp - ACPI help utility
acpihelp <option>
... [<name-prefix>|<hex-value>]
This manual page briefly documents the
acpihelp command. The option list
is taken from the acpihelp interactive help.
acpihelp provides descriptive text for AML and ASL keywords, methods, and
opcodes.
Much more detailed documentation may be found at
http://www.acpica.org/documentation/.
If neither a <name-prefix> or a <hex-value> is provided,
acpihelp will do the logical equivalent of a "display all."
A default search (that is, a search with no options) and a <name-prefix>
can mean two different things: (1) if <name-prefix> does not start with
an underscore, find ASL operator names, or (2) if <name-prefix> does
start with an underscore, find ASL predefined method names.
