For my SoC project I need some mechanism to evaluate the improvement of the input thread inside X.

I’m very happy to say that I was selected again to work on Google Summer of Code with X.Org Foundation.

I was thinking how we could make remotely X clients totally connective with the server when both are behind a NAT/firewall.

Today, Paulo Zanoni help me to put in a shape the VgaArbiter wiki page.

After a long journey I come back in this… So I did a set of benchmarks to evaluate the VGA arbitration versus the RAC usage.

The Resource Access Control inside Xorg is the guy responsible to take care of the various resources of memory and to share them in a wise manner when two or more graphics devices are active (think multi-head).

So we finally have a working code to do the arbitration of the VGA legacy instructions.

I used a part of the money that I earned on the SoC 2007 to buy a laptop to me.

Not so much, but here are the news: * For the final evaluation period on the Summer of Code, Daniel suggest me to start my [own X server tree](http://gitweb.freedesktop.org/?

It’s being a great adventure to lock the X input thread on the memory.

This week I tried to lock in the physical memory the Xorg’s input code using mlock().

In the last week, I did some cool experiments to see the effects of the D state acting on the X server process when I start it with and without the input thread and always mlock’ing it.

This mail that I’ve sent to xorg mailing list tells the current state of my project. cut here - Hi guys.

(In a puny attempt to write my SoC project progress to my mentor, I decided to expand it and share my thoughts with you) Today, we have two methods to register the pointer devices on Xorg server: (1) under SIGIO and (2) put they fd on EnableDevices set.

This week I spent a good time trying to understand the new input hotplug of devices on X and liked a lot.

Certainly, my great new is that I was accepted as a student of X.Org Foundation sponsored by Google, on Summer of Code 2007.

Here is the presentation I’ve given on 8th International Free Software Forum, at Porto Alegre.

…this is the subject of my talk which will be held at FISL (International Free Software Forum) on this saturday, April 14th.

Here is mail that I sent to xorg list a week ago.

MPX brought to us a new idea of multiseat system.

For some reason multiseat doesn’t call much attention in countries that are not of the third world.

This is my first post and even my first blog.
