Kernel driver amc6821
=====================
Supported chips:
Texas Instruments AMC6821
Prefix: 'amc6821'
Addresses scanned: 0x18, 0x19, 0x1a, 0x2c, 0x2d, 0x2e, 0x4c, 0x4d, 0x4e

Description
-----------
This driver implements support for the Texas Instruments amc6821 chip.
The chip has one on-chip and one remote temperature sensor and one pwm fan
regulator.
The pwm can be controlled either from software or automatically.
The driver provides the following sensor accesses in sysfs:
temp1_input ro on-chip temperature
temp1_min rw "
temp1_max rw "
temp1_crit rw "
temp1_min_alarm ro "
temp1_max_alarm ro "

temp2_crit_alarm ro "
temp2_fault ro "
fan1_input ro tachometer speed
fan1_min rw "
fan1_max rw "
fan1_fault ro "
fan1_div rw Fan divisor can be either 2 or 4.
pwm1 rw pwm1
pwm1_enable rw regulator mode, 1=open loop, 2=fan controlled
by remote temperature, 3=fan controlled by
combination of the on-chip temperature and
remote-sensor temperature,
pwm1_auto_channels_temp ro 1 if pwm_enable==2, 3 if pwm_enable==3
pwm1_auto_point1_pwm ro Hardwired to 0, shared for both
temperature channels.
pwm1_auto_point2_pwm rw This value is shared for both temperature
channels.
pwm1_auto_point3_pwm rw Hardwired to 255, shared for both
temperature channels.
temp1_auto_point1_temp ro Hardwired to temp2_auto_point1_temp
which is rw. Below this temperature fan stops.
temp1_auto_point2_temp rw The low-temperature limit of the proportional
range. Below this temperature
pwm1 = pwm1_auto_point2_pwm. It can go from
0 degree C to 124 degree C in steps of
4 degree C. Read it out after writing to get
the actual value.
temp1_auto_point3_temp rw Above this temperature fan runs at maximum
speed. It can go from temp1_auto_point2_temp.
It can only have certain discrete values
which depend on temp1_auto_point2_temp and
pwm1_auto_point2_pwm. Read it out after
writing to get the actual value.
temp2_auto_point1_temp rw Must be between 0 degree C and 63 degree C and
it defines the passive cooling temperature.
Below this temperature the fan stops in
the closed loop mode.
temp2_auto_point2_temp rw The low-temperature limit of the proportional
range. Below this temperature
pwm1 = pwm1_auto_point2_pwm. It can go from
0 degree C to 124 degree C in steps
of 4 degree C.
temp2_auto_point3_temp rw Above this temperature fan runs at maximum
speed. It can only have certain discrete
values which depend on temp2_auto_point2_temp
and pwm1_auto_point2_pwm. Read it out after
writing to get actual value.
Module parameters
-----------------
If your board has a BIOS that initializes the amc6821 correctly, you should
load the module with: init=0.
If your board BIOS doesn't initialize the chip, or you want
different settings, you can set the following parameters:
init=1,
pwminv: 0 default pwm output, 1 inverts pwm output.

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.
All these processors have a sensor, but on those for Socket F or AM2+,
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.
Due to technical reasons, the driver can detect only the mainboard's
socket type, not the processor's actual capabilities. Therefore, if you
are using an AM3 processor on an AM2+ mainboard, you can safely use the
"force=1" 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.

A set of ABS_MT events with the desired properties is defined. The events
are divided into categories, to allow for partial implementation. The
minimum set consists of ABS_MT_TOUCH_MAJOR, ABS_MT_POSITION_X and
ABS_MT_POSITION_Y, which allows for multiple fingers to be tracked. If the
device supports it, the ABS_MT_WIDTH_MAJOR may be used to provide the size

allows for multiple fingers to be tracked. If the device supports it, the
ABS_MT_TOUCH_MAJOR and ABS_MT_WIDTH_MAJOR may be used to provide the size
of the contact area and approaching finger, respectively.
The TOUCH and WIDTH parameters have a geometrical interpretation; imagine
looking through a window at someone gently holding a finger against the
glass. You will see two regions, one inner region consisting of the part
of the finger actually touching the glass, and one outer region formed by
the perimeter of the finger. The diameter of the inner region is the
ABS_MT_TOUCH_MAJOR, the diameter of the outer region is
ABS_MT_WIDTH_MAJOR. Now imagine the person pressing the finger harder
against the glass. The inner region will increase, and in general, the
ratio ABS_MT_TOUCH_MAJOR / ABS_MT_WIDTH_MAJOR, which is always smaller than
unity, is related to the finger pressure. For pressure-based devices,
ABS_MT_PRESSURE may be used to provide the pressure on the contact area
instead.
In addition to the MAJOR parameters, the oval shape of the finger can be
described by adding the MINOR parameters, such that MAJOR and MINOR are the
major and minor axis of an ellipse. Finally, the orientation of the oval
shape can be describe with the ORIENTATION parameter.
The ABS_MT_TOOL_TYPE may be used to specify whether the touching tool is a
finger or a pen or something else. Devices with more granular information
may specify general shapes as blobs, i.e., as a sequence of rectangular
shapes grouped together by an ABS_MT_BLOB_ID. Finally, for the few devices

In the specific application of creating gesture events, the TOUCH and WIDTH
parameters can be used to, e.g., approximate finger pressure or distinguish
between index finger and thumb. With the addition of the MINOR parameters,
one can also distinguish between a sweeping finger and a pointing finger,
and with ORIENTATION, one can detect twisting of fingers.

that initial short description onto a second line, that second line will
appear further down at the beginning of the description section, which is
almost certainly not what you had in mind.
All "description" text can span multiple lines, although the
function_name & its short description are traditionally on a single line.
Description text may also contain blank lines (i.e., lines that contain

"section header:" names must be unique per function (or struct,

HAVE_FUNCTION_GRAPH_FP_TEST
---------------------------
An arch may pass in a unique value (frame pointer) to both the entering and
exiting of a function. On exit, the value is compared and if it does not
match, then it will panic the kernel. This is largely a sanity check for bad
code generation with gcc. If gcc for your port sanely updates the frame
pointer under different opitmization levels, then ignore this option.
However, adding support for it isn't terribly difficult. In your assembly code
that calls prepare_ftrace_return(), pass the frame pointer as the 3rd argument.
Then in the C version of that function, do what the x86 port does and pass it
along to ftrace_push_return_trace() instead of a stub value of 0.
Similarly, when you call ftrace_return_to_handler(), pass it the frame pointer.
