module Ohai::Common::DMI
Constants
- ID_TO_CAPTURE
list of IDs to collect, otherwise we generate pages of hashes about cache chip size and whatnot See OHAI-260. When we can give the user a choice, this will be a default.
- ID_TO_DESCRIPTION
List of IDs and what they translate to from 'man 8 dmidecode' all-lowercase, all non-alphanumeric converted to '_' 128-255 are 'oem_data_' Everything else is 'unknown'
Public Class Methods
create simplified convenience access keys for each record type for single occurrences of one type, copy to top level all fields and values for multiple occurrences of same type, copy to top level all fields and values that are common to all records
