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
of the approaching finger. Anisotropy and direction may be specified with

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.

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.
