Hi all
I am trying to understand the kernel memory management and require assistance in this regard. Kernel first creates the cache memory to perform any subsequent allocation to processes. I could not figure out how it is accomplished. Do kernel directly allocates any hardware cache or allocates... (0 Replies)
Hi all
I saw in Microsoft web site www.SysInternals.com a tool called CoreInfo from able to print out on screen the size of the Data and Instruction caches of your processor, the Locigal to Physical Processor mapping, the number of the CPU sockets. etc..

Hi All,
could any one point out any open source test-suites for "File cache" testing and as well as performance test suites for the same. Currently my system is up with Linux/ext4.

libcache
libcache(3) BSD Library Functions Manual libcache(3)NAME
libcache -- the caching framework
SYNOPSIS
#include <cache.h>
DESCRIPTION
The libcache framework provides a facility for creating in memory data caches. Each cache is a mutable dictionary that associates values
with their keys. A cache limits the number of values it keeps according to available system memory and selects values to evict when the
limit is exceeded. Recently and frequently used values are less likely to be selected for eviction.
Cache keys and values should be cast as pointers. The framework provides a callback interface for supporting arbitrary types of keys and
values and implements callback functions for common types. See cache_callbacks(3) for more information.
Clients retrieve a value previously added to a cache using the value's key. When the client gets a value, the cache increments a reference
count on the value. When the client finishes with a value retrieved from a cache they must release the value back to the cache. Referenced
values are considered in use and will not be evicted. The cache may evict unreferenced values (e.g. to make room for other values or reduce
its size).
The number of values allowed in a cache at one time is managed by the cache framework. Cache size will grow when the system has available
memory and shrink under memory pressure.
Libcache is thread-safe. It is not safe to call back into the cache API from cache callback functions.
