20 Linux requires an ACPI-compliant platform (hardware/firmware),
25 Linux ACPI provides a robust functional replacement for several
29 Management (APM) specification. If both ACPI and APM support
30 are configured, ACPI is used.
32 Linux support for ACPI is based on Intel Corporation's ACPI
33 Component Architecture (ACPI CA). For more information on the
34 ACPI CA, see:

159 Thus this option is a debug option that helps to write ACPI drivers
