This text documents some starting points in developing GEOM classes, and kernel modules in general. It is assumed that the reader is familiar with C userland programming. Este texto documenta alguns pontos de partida no desenvolvimento de classes GEOM e módulos do kernel em geral. Supõe-se que o leitor esteja familiarizado com a programação C do userland.
Introduction Introdução
Documentation Documentação
Documentation on kernel programming is scarce — it is one of few areas where there is nearly nothing in the way of friendly tutorials, and the phrase <quote>use the source!</quote> really holds true. However, there are some bits and pieces (some of them seriously outdated) floating around that should be studied before beginning to code: A documentação sobre programação do kernel é escassa - é uma das poucas áreas na qual não há quase nada de tutoriais amigáveis, e a frase <quote>usa a fonte!</quote> realmente é verdadeira. No entanto, existem alguns pedaços (alguns deles seriamente desatualizados) flutuando por ai e que devem ser estudados antes de começar a codificar:
The <link xlink:href="@@URL_RELPREFIX@@/doc/en_US.ISO8859-1/books/developers-handbook/index.html">FreeBSD Developer's Handbook</link> — part of the documentation project, it does not contain anything specific to kernel programming, but rather some general useful information. O <link xlink:href="@@URL_RELPREFIX@@/doc/en_US.ISO8859-1/books/developers-handbook/index.html">Manual do Desenvolvedor do FreeBSD</link> - parte do projeto de documentação, ele não contém nenhum informação específica para a programação do kernel, mas possui algumas informações gerais úteis.
The <link xlink:href="@@URL_RELPREFIX@@/doc/en_US.ISO8859-1/books/arch-handbook/index.html">FreeBSD Architecture Handbook</link> — also from the documentation project, contains descriptions of several low-level facilities and procedures. The most important chapter is 13, <link xlink:href="@@URL_RELPREFIX@@/doc/en_US.ISO8859-1/books/arch-handbook/driverbasics.html">Writing FreeBSD device drivers</link>. O <link xlink:href="@@URL_RELPREFIX@@/doc/en_US.ISO8859-1/books/arch-handbook/index.html">Manual de Arquitetura do FreeBSD</link> - também do projeto de documentação, contém descrições de várias instalações e procedimentos de baixo nível. O capítulo mais importante é o 13, <link xlink:href="@@URL_RELPREFIX@@/doc/en_US.ISO8859-1/books/arch-handbook/driverbasics.html">Escrevendo drivers de dispositivo FreeBSD</link>.
The Blueprints section of <link xlink:href="http://www.freebsddiary.org">FreeBSD Diary</link> web site — contains several interesting articles on kernel facilities. A seção Blueprints do site do <link xlink:href="http://www.freebsddiary.org">FreeBSD Diary</link> contém vários artigos interessantes sobre os recursos do kernel.

Preliminaries Preliminares
The best way to do kernel development is to have (at least) two separate computers. One of these would contain the development environment and sources, and the other would be used to test the newly written code by network-booting and network-mounting filesystems from the first one. This way if the new code contains bugs and crashes the machine, it will not mess up the sources (and other <quote>live</quote> data). The second system does not even require a proper display. Instead, it could be connected with a serial cable or KVM to the first one. A melhor maneira de fazer o desenvolvimento do kernel é ter (pelo menos) dois computadores separados. Um deles conteria o ambiente de desenvolvimento e o código fonte, e o outro seria usado para testar o código recém escrito, inicializando por meio da rede e montando seu sistema de arquivo a partir do primeiro computador. Desta forma, se o novo código contiver erros e travar a máquina, isso não irá atrapalhar o código fonte (e nem nenhum outros dado <quote>vivo</quote>). O segundo sistema nem sequer requer um monitor adequado. Em vez disso, ele pode ser conectado por meio de um cabo serial ou KVM ao primeiro computador.
But, since not everybody has two or more computers handy, there are a few things that can be done to prepare an otherwise <quote>live</quote> system for developing kernel code. This setup is also applicable for developing in a <link xlink:href="http://www.vmware.com/">VMWare</link> or <link xlink:href="http://www.qemu.org/">QEmu</link> virtual machine (the next best thing after a dedicated development machine). Mas, como nem todo mundo tem dois ou mais computadores à mão, há algumas coisas que podem ser feitas para preparar um sistema <quote>vivo </quote> para desenvolver código para o kernel. Esta configuração também é aplicável para desenvolvimento em uma máquina virtual criada com o <link xlink:href="http://www.vmware.com/">VMWare</link> ou com o <link xlink:href="http://www.qemu.org/">QEmu</link> (a próxima melhor coisa depois de uma máquina de desenvolvimento dedicada).
