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).

Description:
|
||||||
|
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.

The sanity_checks file specifies whether expensive checks

The shrink file is written when memory should be reclaimed from

a cache. Empty partial slabs are freed and the partial list is

sorted so the slabs with the fewest available objects are used

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.
