KCachegrind
|
||
|
|
===========
|
||
|
|
|
||
|
|
|
||
|
|
What is all this about ?
|
||
|
|
-------------------------
|
||
|
|
|
||
|
|
Profiling, i.e. determinating most time consuming execution parts,
|
||
|
|
is an important last step when developing applications.
|
||
|
|
KCachegrind visualizes traces, generated by profiling, in various ways;
|
||
|
|
most notable is the TreeMap visualization of the calls happening
|
||
|
|
and a condensed version of it, the Coverage analysis.
|
||
|
|
KCachegrind is designed to allow fast browsing and to provide a quick
|
||
|
|
overview of very large programs, such as KDE applications (but not
|
||
|
|
limited to!).
|
||
|
|
|
||
|
|
At the moment, it uses Cachegrind as profiling backend, which is using
|
||
|
|
the excellent CPU simulator in Valgrind. Thus, profiling does not
|
||
|
|
need any preparation, can cope with shared libraries and plugin
|
||
|
|
architectures, and allows for profile runs to not influence the measuring
|
||
|
|
by the profile itself (all in contrast to e.g. GProf). Disadvantage is
|
||
|
|
slower profile runs, unfortunately.
|
||
|
|
|
||
|
|
For Cachegrind to provide call tree information, a patch is provided.
|
||
|
|
This enables the most interesting visualization features of KCachegrind.
|
||
|

Requirements
|
||
|
|
------------
|
||
|
|
|
||
|
|
A call-tree version of Cachegrind:
|
||
|
|
- X86 Linux
|
||
|
|
- Valgrind 1.0.x with call-tree patch from KCachegrind Website
|
||
|
|
- Valgrind 2.0.x with call-tree skin installed
|
||
|
|
|
||
|
|
Cachegrind runs on x86 platforms, KCachegrind on all KDE enabled
|
||
|
|
platforms (KDE 3.0.x).
|
||
|
|
|
||
|
|
|
||
|
|
Compilation and Installation
|
||
|
|
----------------------------
|
||
|
|
|
||
|
|
Simple do the command sequence
|
||
|
|
|
||
|
|
./configure --prefix=<KDE base directory>
|
||
|
|
make
|
||
|
|
make install
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
KCachegrind features
|
||
|
|
--------------------
|
||
|
|
|
||
|
|
Most important: TreeMap calltree visualisation.
|
||
|
|

|
||
|

each part of KCachegrind and the quick starter on the
