"on" means that the device is not allowed to autosuspend,

be honored. "auto" means the device will autosuspend
and autoresume in the usual manner, according to the
capabilities of its driver. "suspend" means the device
is forced into a suspended state and it will not autoresume
in response to I/O requests. However remote-wakeup requests
from the device may still be enabled (the remote-wakeup

If you want to suspend a device immediately but leave it

write "0" to power/autosuspend.

devices to support suspend/resume, many of them do not.

Description
-----------
This driver permits reading of the internal temperature sensor of AMD
Family 10h and 11h processors.
All these processors have a sensor, but on older revisions of Family 10h
processors, the sensor may return inconsistent values (erratum 319). The
driver will refuse to load on these revisions unless you specify the
"force=1" module parameter.
There is one temperature measurement value, available as temp1_input in
sysfs. It is measured in degrees Celsius with a resolution of 1/8th degree.
Please note that it is defined as a relative value; to quote the AMD manual:
Tctl is the processor temperature control value, used by the platform to
control cooling systems. Tctl is a non-physical temperature on an
arbitrary scale measured in degrees. It does _not_ represent an actual
physical temperature like die or case temperature. Instead, it specifies
the processor temperature relative to the point at which the system must
supply the maximum cooling for the processor's specified maximum case
temperature and maximum thermal power dissipation.
The maximum value for Tctl is available in the file temp1_max.
If the BIOS has enabled hardware temperature control, the threshold at
which the processor will throttle itself to avoid damage is available in
temp1_crit and temp1_crit_hyst.

6. Run-time PM and System Sleep
Run-time PM and system sleep (i.e., system suspend and hibernation, also known
as suspend-to-RAM and suspend-to-disk) interact with each other in a couple of
ways. If a device is active when a system sleep starts, everything is
straightforward. But what should happen if the device is already suspended?
The device may have different wake-up settings for run-time PM and system sleep.
For example, remote wake-up may be enabled for run-time suspend but disallowed
for system sleep (device_may_wakeup(dev) returns 'false'). When this happens,
the subsystem-level system suspend callback is responsible for changing the
device's wake-up setting (it may leave that to the device driver's system
suspend routine). It may be necessary to resume the device and suspend it again
in order to do so. The same is true if the driver uses different power levels
or other settings for run-time suspend and system sleep.
During system resume, devices generally should be brought back to full power,
even if they were suspended before the system sleep began. There are several
reasons for this, including:
* The device might need to switch power levels, wake-up settings, etc.
* Remote wake-up events might have been lost by the firmware.
* The device's children may need the device to be at full power in order
to resume themselves.
* The driver's idea of the device state may not agree with the device's
physical state. This can happen during resume from hibernation.
* The device might need to be reset.
* Even though the device was suspended, if its usage counter was > 0 then most
likely it would need a run-time resume in the near future anyway.
* Always going back to full power is simplest.
If the device was suspended before the sleep began, then its run-time PM status
will have to be updated to reflect the actual post-system sleep status. The way
to do this is:
pm_runtime_disable(dev);
pm_runtime_set_active(dev);
pm_runtime_enable(dev);
The PM core always increments the run-time usage counter before calling the
->prepare() callback and decrements it after calling the ->complete() callback.
Hence disabling run-time PM temporarily like this will not cause any run-time
suspend callbacks to be lost.

* OpenPIC and its interrupt numbers on Freescale's e500/e600 cores
The OpenPIC specification does not specify which interrupt source has to
become which interrupt number. This is up to the software implementation
of the interrupt controller. The only requirement is that every
interrupt source has to have an unique interrupt number / vector number.
To accomplish this the current implementation assigns the number zero to
the first source, the number one to the second source and so on until
all interrupt sources have their unique number.
Usually the assigned vector number equals the interrupt number mentioned
in the documentation for a given core / CPU. This is however not true
for the e500 cores (MPC85XX CPUs) where the documentation distinguishes
between internal and external interrupt sources and starts counting at
zero for both of them.
So what to write for external interrupt source X or internal interrupt
source Y into the device tree? Here is an example:
The memory map for the interrupt controller in the MPC8544[0] shows,
that the first interrupt source starts at 0x5_0000 (PIC Register Address
Map-Interrupt Source Configuration Registers). This source becomes the
number zero therefore:
External interrupt 0 = interrupt number 0
External interrupt 1 = interrupt number 1
External interrupt 2 = interrupt number 2
...
Every interrupt number allocates 0x20 bytes register space. So to get
its number it is sufficient to shift the lower 16bits to right by five.
So for the external interrupt 10 we have:
0x0140 >> 5 = 10
After the external sources, the internal sources follow. The in core I2C
controller on the MPC8544 for instance has the internal source number
27. Oo obtain its interrupt number we take the lower 16bits of its memory
address (0x5_0560) and shift it right:
0x0560 >> 5 = 43
Therefore the I2C device node for the MPC8544 CPU has to have the
interrupt number 43 specified in the device tree.

Forms of dynamic PM
-------------------
Dynamic suspends can occur in two ways: manual and automatic.
"Manual" means that the user has told the kernel to suspend a device,
whereas "automatic" means that the kernel has decided all by itself to
suspend a device. Automatic suspend is called "autosuspend" for
short. In general, a device won't be autosuspended unless it has been
idle for some minimum period of time, the so-called idle-delay time.
Dynamic suspends occur when the kernel decides to suspend an idle
device. This is called "autosuspend" for short. In general, a device
won't be autosuspended unless it has been idle for some minimum period
of time, the so-called idle-delay time.

resume as soon as the system suspend is complete. Or the remote
wakeup may fail and get lost. Which outcome occurs depends on timing
and on the hardware and firmware design.
More interestingly, a device might undergo a manual resume or
autoresume during system suspend. With current kernels this shouldn't
happen, because manual resumes must be initiated by userspace and
autoresumes happen in response to I/O requests, but all user processes
and I/O should be quiescent during a system suspend -- thanks to the
freezer. However there are plans to do away with the freezer, which
would mean these things would become possible. If and when this comes
about, the USB core will carefully arrange matters so that either type
of resume will block until the entire system has resumed.

config CMDLINE_BOOL
bool "Built-in kernel command line"

help
For most systems, it is firmware or second stage bootloader that
by default specifies the kernel command line options. However,
it might be necessary or advantageous to either override the
default kernel command line or add a few extra options to it.
For such cases, this option allows you to hardcode your own
command line options directly into the kernel. For that, you
should choose 'Y' here, and fill in the extra boot arguments
in CONFIG_CMDLINE.
The built-in options will be concatenated to the default command
line if CMDLINE_OVERRIDE is set to 'N'. Otherwise, the default
command line will be ignored and replaced by the built-in string.
Most MIPS systems will normally expect 'N' here and rely upon
the command line from the firmware or the second-stage bootloader.

pass arguments to the kernel. For these platforms, you can supply
some command-line options at build time by entering them here. In
other cases you can specify kernel args so that you don't have
to set them up in board prom initialization routines.
pass arguments to the kernel. For these platforms, and for the cases
when you want to add some extra options to the command line or ignore
the default command line, you can supply some command-line options at
build time by entering them here. In other cases you can specify
kernel args so that you don't have to set them up in board prom
initialization routines.
For more information, see the CMDLINE_BOOL and CMDLINE_OVERRIDE
options.
config CMDLINE_OVERRIDE
bool "Built-in command line overrides firware arguments"
default n
depends on CMDLINE_BOOL
help
By setting this option to 'Y' you will have your kernel ignore
command line arguments from firmware or second stage bootloader.
Instead, the built-in command line will be used exclusively.
Normally, you will choose 'N' here.
config DEBUG_STACK_USAGE
bool "Enable stack utilization instrumentation"

help
Pre-series (prototype) units are different from later ones in
some ways. Select this option if you have one of these. Please
note that a kernel built with this option selected will not be
able to run on normal units.
