Os desenvolvedores do sistema operacional Redox, escrito com a linguagem Rust e baseado no conceito de microkernel, publicaram um relat\u00f3rio sobre o progresso do projeto em maio. Entre os feitos, destacou-se a bem-sucedida portabilidade do ambiente de desktop Xfce. O funcionamento do Xfce no Redox foi considerado mais est\u00e1vel do que o funcionamento da portabilidade anterior com o desktop MATE, que ainda apresenta problemas n\u00e3o resolvidos com o gerenciador de arquivos Caja.<\/p>\n

<\/p>\n

Para o Redox, tamb\u00e9m foi implementado um novo escalonador de tarefas que utiliza o algoritmo EEVDF (Earliest Eligible Virtual Deadline First). O novo escalonador, ao escolher o pr\u00f3ximo processo para execu\u00e7\u00e3o, considera aqueles que n\u00e3o receberam recursos de CPU suficientes ou que receberam tempo de CPU injustificadamente excessivo. No primeiro caso, a transfer\u00eancia de controle \u00e9 for\u00e7ada ao processo, enquanto no segundo, \u00e9 adiada. <\/p>\n

Foi dada continuidade ao aprimoramento da compatibilidade com a biblioteca padr\u00e3o C POSIX relibc, escrita em Rust. O driver de pseudoterminais foi melhorado. Suporte parcial para limita\u00e7\u00e3o de recursos foi adicionado atrav\u00e9s do mecanismo rlimit.
\nA performance das opera\u00e7\u00f5es poll e epoll foi significativamente aumentada (at\u00e9 4 vezes durante os testes no QEMU). O cache de inode foi implementado, reduzindo o tempo de compila\u00e7\u00e3o de testes no GCC de 2411 ms para 670 ms. A compila\u00e7\u00e3o incremental de mudan\u00e7as em pacotes tamb\u00e9m foi realizada. <\/p>\n

Do ambiente de desktop COSMIC, foi portado um interface gr\u00e1fica para monitorar o estado do sistema. A capacidade de configurar as fontes no emulador de terminal foi adicionada. O CPython 3.15 e o libdrm foram portados. <\/p>\n

<\/p>\n

O sistema operacional Redox se desenvolve de acordo com a filosofia Unix e incorpora algumas ideias do SeL4, Minix e Plan 9. O Redox utiliza o conceito de microkernel, onde no n\u00edvel do kernel apenas a intera\u00e7\u00e3o entre processos e a gest\u00e3o de recursos s\u00e3o garantidas, enquanto toda a funcionalidade restante \u00e9 transferida para bibliotecas que podem ser utilizadas tanto pelo kernel quanto por aplicativos de usu\u00e1rio. Todos os drivers s\u00e3o executados no espa\u00e7o do usu\u00e1rio em ambientes sandbox isolados. <\/p>\n

O projeto desenvolve seu pr\u00f3prio gerenciador de pacotes, um conjunto de utilit\u00e1rios padr\u00e3o (binutils, coreutils, netutils, extrautils), o shell de comando ion, a biblioteca padr\u00e3o C relibc, um editor de texto semelhante ao vim chamado sodium, a pilha de rede e o sistema de arquivos. A configura\u00e7\u00e3o \u00e9 definida na linguagem Toml. Para compatibilidade com aplicativos existentes, uma camada POSIX \u00e9 fornecida, permitindo a execu\u00e7\u00e3o de muitos programas sem necessidade de porte.<\/p>\n

Voc\u00ea pode testar o Redox utilizando as compila\u00e7\u00f5es atualizadas diariamente para m\u00e1quinas virtuais<\/a> e hardware real (aarch64, i586, i686, riscv64gc, x86_64). Entre os dispositivos compat\u00edveis, destacam-se os que possuem interface USB, chips de som AC'97 e Intel HD Audio, USB, SATA (AHCI, IDE) e NVMe.
\nPara a sa\u00edda gr\u00e1fica, podem ser utilizados os APIs VESA BIOS, UEFI GOP ou o driver para GPU Intel. O suporte a Wi-Fi e Bluetooth ainda n\u00e3o est\u00e1 completo.
