x86: start unification of arch/x86/Kconfig.*
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.

|

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
|

|
||||
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

|

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.

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
|

this feature.

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.)

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

On PCI systems, the BIOS can be used to detect the PCI devices and

determine their configuration. However, some old PCI motherboards

PCI-based systems don't have any BIOS at all. Linux can also try to

if you choose "Direct", the BIOS won't be used, and if you

If you choose "Any", the kernel will try MMCONFIG, then the

direct access method and falls back to the BIOS if that doesn't

work. If unsure, go with the default, which is "Any".
