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).

The file remote_node_defrag_ratio specifies the percentage of

times SLUB will attempt to refill the cpu slab with a partial

slab from a remote node as opposed to allocating a new slab on

the local node. This reduces the amount of wasted memory over

the entire system but can be expensive.

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

Creation of the self-extracting compressed kernel image (vmlinuz)
|
||||
-----------------------------------------------------------------
|

$Id: README,v 1.1 2001/12/17 13:59:27 bjornw Exp $
|
||||
|
||||
This can be slightly confusing because it's a process with many steps.
|
||||
|
||||
The kernel object built by the arch/etrax100/Makefile, vmlinux, is split
|
||||
by that makefile into text and data binary files, vmlinux.text and
|
||||
vmlinux.data.
|
||||
|
||||
Those files together with a ROM filesystem can be catted together and
|
||||
burned into a flash or executed directly at the DRAM origin.
|
||||
|
||||
They can also be catted together and compressed with gzip, which is what
|
||||
happens in this makefile. Together they make up piggy.img.
|
||||
|
||||
The decompressor is built into the file decompress.o. It is turned into
|
||||
the binary file decompress.bin, which is catted together with piggy.img
|
||||
into the file vmlinuz. It can be executed in an arbitrary place in flash.
|
||||
|
||||
Be careful - it assumes some things about free locations in DRAM. It
|
||||
assumes the DRAM starts at 0x40000000 and that it is at least 8 MB,
|
||||
so it puts its code at 0x40700000, and initial stack at 0x40800000.
