Description:
|
||||
The /sys/kernel/slab directory contains a snapshot of the
|
||||
internal state of the SLUB allocator for each cache. Certain
|
||||
files may be modified to change the behavior of the cache (and
|
||||
any cache it aliases, if any).

Event Computation
|

-----------------
|

|

The flora of different hardware unavoidably leads to some devices fitting
|
||||
better to the MT protocol than others. To simplify and unify the mapping,
|
||||
this section gives recipes for how to compute certain events.
|
||||
|
||||
For devices reporting contacts as rectangular shapes, signed orientation
|
||||
cannot be obtained. Assuming X and Y are the lengths of the sides of the
|
||||
touching rectangle, here is a simple formula that retains the most
|
||||
information possible:
|
||||
|
||||
ABS_MT_TOUCH_MAJOR := max(X, Y)
|
||||
ABS_MT_TOUCH_MINOR := min(X, Y)
|
||||
ABS_MT_ORIENTATION := bool(X > Y)
|
||||
|
||||
The range of ABS_MT_ORIENTATION should be set to [0, 1], to indicate that
|
||||
the device can distinguish between a finger along the Y axis (0) and a
|
||||
finger along the X axis (1).

The process of finger tracking, i.e., to assign a unique trackingID to each

fingers is a euclidian bipartite matching problem at each event update, and

Paravirtualized spinlocks allow a pvops backend to replace the
|
||||
spinlock implementation with something virtualization-friendly
|
||||
(for example, block the virtual CPU rather than spinning).
|
||||
|
||||
Unfortunately the downside is an up to 5% performance hit on
|
||||
native kernels, with various workloads.

If you are unsure how to answer this question, answer N.
