If you are compiling for a + mobile system, say Y. + +CONFIG_ACPI_PROCESSOR + This driver installs ACPI as the idle handler for Linux, and uses + ACPI C2 and C3 processor states to save power, on systems that + support it. + +CONFIG_ACPI_THERMAL + This driver adds support for ACPI thermal zones. Most mobile and + some desktop systems support ACPI thermal zones. It is HIGHLY + recommended that this option be enabled, as your processor(s) + may be damaged without it. + +CONFIG_ACPI_FAN + This driver adds support for ACPI fan devices, allowing user-mode + applications to perform basic fan control (on, off, status). + +CONFIG_ACPI_SYSTEM + This driver will enable your system to shut down using ACPI, and + dump your ACPI DSDT table using /proc/acpi/dsdt. + +CONFIG_ACPI_DEBUG + The ACPI driver can optionally report errors with a great deal + of verbosity. Saying Y enables these statements. This will increase + your kernel size by around 50K. + diff -Naur -X bin/dontdiff linux-old-24/drivers/acpi/Config.in linux-24/drivers/acpi/Config.in --- linux-old-24/drivers/acpi/Config.in Wed Jun 20 17:47:39 2001 +++ linux-24/drivers/acpi/Config.in Fri Jul 26 11:50:55 2002 @@ -1,17 +1,84 @@ # -# ACPI configuration +# ACPI Configuration # -#mainmenu_option next_comment -#comment 'ACPI Configuration' -dep_bool ' ACPI Debug Statements' CONFIG_ACPI_DEBUG $CONFIG_ACPI -dep_tristate ' ACPI Bus Manager' CONFIG_ACPI_BUSMGR $CONFIG_ACPI +if [ "$CONFIG_X86" = "y" ];
