DOT call graphs of Rik and AA VMs

DOT call graphs of Rik and AA VMs

[Martin Devera]

Hi,

While I tried to understand MM in 2.4 kernels I decided to create call
graph of it (in DOT). It could help everyone who tries to understand it.

At least they are very nice :) You can also see difference in complexity
of both VMs.

Oh my that is cute.     Will you be publishing the gcc patch
and perl script sometime?

Oh yes, it's really lovely.  An great starting point for reverse-enginee^W^W 
understanding both VM designs.

Virtual Wire v.s. APIC

[Earle Nietzel]

Under the new 2.4.x series kernel, should you use the APIC mode?

Or do you have to continue using the Virtual Wire mode?

Thanks for any answers...





P.S. I am only participating on the linux-smp so any linux-kernel replies 
please forward me a copy, thanx.

I have never seen bsd sources so it would take too many
time to undestand its structure probably. But I will
release patches and you can do it :)

There are sources and various notes (printing) on site mentioned above.
There is idea of dynamic generator for all kernels too.

At http://luxik.cdi.cz/~devik/mm.htm is update. Actualy dot can't scale
it. You can do it yourself (several postscript lines) or try psutils.

Given high enough demand I'll create script which will scale it
automatically for printer.

I tried to import the "ps" files into Acrobat 5.0 on my Windows system and
it cut them off to a single 8" by 10.5" page.

RE: DOT call graphs of Rik and AA VMs

[Martin Devera]

Yes it will. As I said the dot makes too big pages. It is described
in its man page section bugs.
Did you applied the patch I posted now ? It should make it
printable.
Probably I should post print-ready version of these pages, shouldn't I ?

RE: DOT call graphs of Rik and AA VMs

[Martin Devera]

Hello Edward,

I updated both PS files so that they should print on A4. Try
do redownload them (probably with holding Shift in IE to bypass
cache) and print.
Please tell me whether is it ok. I just printed them using
gs on linux and it is nicely readable on my LJ4.

RE: DOT call graphs of Rik and AA VMs

[M. Edward Borasky]

They look good now! The ac3 one comes in rotated (landscape format on a
portrait page) but Acrobat will rotate it (90 degrees clockwise) and then it
looks fine. "mm2412" comes in correctly in portrait format. Both require the
"zoom-in" tool for me to make sense of them, but I can print them on a
larger page if I need hard copy.

RE: DOT call graphs of Rik and AA VMs

[Martin Devera]

Yes I rotated it so it fits A4 page nicely. When you print
it on A4 you should be able to read labels nicely.
