NAME

6       acpihelp - ACPI help utility
7

SYNOPSIS

9       acpihelp <option>...  [<name-prefix>|<hex-value>]
10
11

DESCRIPTION

13       This  manual  page  briefly  documents the acpihelp command. The option
14       list is taken from the acpihelp interactive help.
15
16       acpihelp provides descriptive text for AML and ASL  keywords,  methods,
17       and opcodes.
18
19       Much     more     detailed    documentation    may    be    found    at
20       http://www.acpica.org/documentation/.
21
22       If neither a <name-prefix> or a <hex-value> is provided, acpihelp  will
23       do the logical equivalent of a "display all."
24
25       A  default  search (that is, a search with no options) and a <name-pre‐
26       fix> can mean two different things: (1) if <name-prefix> does not start
27       with  an  underscore,  find ASL operator names, or (2) if <name-prefix>
28       does start with an underscore, find ASL predefined method names.
