NAME
       acpihelp - ACPI help utility

SYNOPSIS
       acpihelp <option>...  [<name-prefix>|<hex-value>]

DESCRIPTION
       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 dif-
       ferent 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.

OPTIONS
   ACPI Names and Symbols
       -k [<name-prefix>]
	      Find/Display ASL non-operator keyword(s)

       -m [<name-prefix>]

       -p [<name-prefix>]

       -s [<name-prefix>]
	      Find/Display ASL operator name(s)

   ACPI Values
       -e [<hex-value>]

       -i     Display known ACPI Device IDs (_HID)
