From
Subject[PATCH] x86: start unification of arch/x86/Kconfig.*
Date
This step introduces the file arch/x86/Kconfig
which contains all the menu's from "Power Management"
and below.

The main part of the new Kconfig file is shared
and the remaining i386/x86_64 specific symbols
are covered by dependencies.

A x86_64 allmodconfig build did not show any differences.

+ ---help---
+ APM is a BIOS specification for saving power using several different
+ techniques. This is mostly useful for battery powered laptops with
+ APM compliant BIOSes. If you say Y here, the system time will be
+ reset after a RESUME operation, the /proc/apm device will provide
+ battery status information, and user-space programs will receive
+ notification of APM "events" (e.g. battery status change).
+
+ If you select "Y" here, you can disable actual use of the APM
+ BIOS by passing the "apm=off" option to the kernel at boot time.
+
+ Note that the APM support is almost completely disabled for
+ machines with more than one CPU.
+
+ In order to use APM, you will need supporting software. For location
+ and more information, read <file:Documentation/pm.txt> and the
+ Battery Powered Linux mini-HOWTO, available from
+ <http://www.tldp.org/docs.html#howto>.
+
+ This driver does not spin down disk drives (see the hdparm(8)
+ manpage ("man 8 hdparm") for that), and it doesn't turn off
+ VESA-compliant "green" monitors.
+
+ This driver does not support the TI 4000M TravelMate and the ACER
+ 486/DX4/75 because they don't have compliant BIOSes. Many "green"
+ desktop machines also don't have compliant BIOSes, and this driver
+ may cause those machines to panic during the boot phase.
+
+ Generally, if you don't have a battery in your machine, there isn't
+ much point in using this driver and you should say N. If you get
+ random kernel OOPSes or reboots that don't seem to be related to
+ anything, try disabling/enabling this option (or disabling/enabling
+ APM in your BIOS).
+
+ Some other things you should try when experiencing seemingly random,
+ "weird" problems:
+
+ 1) make sure that you have enough swap space and that it is
+ enabled.
+ 2) pass the "no-hlt" option to the kernel
+ 3) switch on floating point emulation in the kernel and pass
+ the "no387" option to the kernel
+ 4) pass the "floppy=nodma" option to the kernel
+ 5) pass the "mem=4M" option to the kernel (thereby disabling
+ all but the first 4 MB of RAM)
+ 6) make sure that the CPU is not over clocked.
+ 7) read the sig11 FAQ at <http://www.bitwizard.nl/sig11/>
+ 8) disable the cache from your BIOS settings
+ 9) install a fan for the video card or exchange video RAM
+ 10) install a better fan for the CPU
+ 11) exchange RAM chips
+ 12) exchange the motherboard.
+
+ To compile this driver as a module, choose M here: the
+ module will be called apm.

+
+config APM_IGNORE_USER_SUSPEND
+ bool "Ignore USER SUSPEND"
+ help
+ This option will ignore USER SUSPEND requests. On machines with a
+ compliant APM BIOS, you want to say N. However, on the NEC Versa M
+ series notebooks, it is necessary to say Y because of a BIOS bug.
+
+config APM_DO_ENABLE
+ bool "Enable PM at boot time"
+ ---help---
+ Enable APM features at boot time. From page 36 of the APM BIOS
+ specification: "When disabled, the APM BIOS does not automatically
+ power manage devices, enter the Standby State, enter the Suspend
+ State, or take power saving steps in response to CPU Idle calls."
+ This driver will make CPU Idle calls when Linux is idle (unless this
+ feature is turned off -- see "Do CPU IDLE calls", below). This
+ should always save battery power, but more complicated APM features
+ will be dependent on your BIOS implementation. You may need to turn
+ this option off if your computer hangs at boot time when using APM
+ support, or if it beeps continuously instead of suspending. Turn
+ this off if you have a NEC UltraLite Versa 33/C or a Toshiba
+ T400CDT. This is off by default since most machines do fine without
+ this feature.
+
+config APM_CPU_IDLE
+ bool "Make CPU Idle calls when idle"
+ help
+ Enable calls to APM CPU Idle/CPU Busy inside the kernel's idle loop.
+ On some machines, this can activate improved power savings, such as
+ a slowed CPU clock rate, when the machine is idle. These idle calls
+ are made after the idle loop has run for some length of time (e.g.,
+ 333 mS). On some machines, this will cause a hang at boot time or
+ whenever the CPU becomes idle. (On machines with more than one CPU,
+ this option does nothing.)
+
+config APM_DISPLAY_BLANK
+ bool "Enable console blanking using APM"
+ help
+ Enable console blanking using the APM. Some laptops can use this to
+ turn off the LCD backlight when the screen blanker of the Linux
+ virtual console blanks the screen. Note that this is only used by
+ the virtual console screen blanker, and won't turn off the backlight
+ when using the X Window system. This also doesn't have anything to
+ do with your VESA-compliant power-saving monitor. Further, this
+ option doesn't work for all laptops -- it might not turn off your
+ backlight at all, or it might print a lot of errors to the console,
+ especially if you are using gpm.
+
+config APM_ALLOW_INTS
+ bool "Allow interrupts during APM BIOS calls"
+ help
+ Normally we disable external interrupts while we are making calls to
+ the APM BIOS as a measure to lessen the effects of a badly behaving
+ BIOS implementation. The BIOS should reenable interrupts if it
+ needs to. Unfortunately, some BIOSes do not -- especially those in
+ many of the newer IBM Thinkpads. If you experience hangs when you
+ suspend, try setting this to Y. Otherwise, say N.
+
+config APM_REAL_MODE_POWER_OFF

- This provides basic support for National Semiconductor's
- (now AMD's) Geode processors. The driver probes for the
- PCI-IDs of several on-chip devices, so its a good dependency
- for other scx200_* drivers.
-
- If compiled as a module, the driver is named scx200.

-config SCx200HR_TIMER

- depends on SCx200 && GENERIC_TIME
- default y
- help
- This driver provides a clocksource built upon the on-chip
- 27MHz high-resolution timer. Its also a workaround for
- NSC Geode SC-1100's buggy TSC, which loses time when the
- processor goes idle (as is done by the scheduler). The
- other workaround is idle=poll boot option.

-config GEODE_MFGPT_TIMER
- bool "Geode Multi-Function General Purpose Timer (MFGPT) events"
- depends on MGEODE_LX && GENERIC_TIME && GENERIC_CLOCKEVENTS
- default y
- help
- This driver provides a clock event source based on the MFGPT
- timer(s) in the CS5535 and CS5536 companion chip for the geode.
- MFGPTs have a better resolution and max interval than the
- generic PIT, and are suitable for use as high-res timers.
