A Intel apresentou<\/a><\/noindex> Na confer\u00eancia OSTS (Open Source Technology Summit) que est\u00e1 acontecendo estes dias, v\u00e1rios novos projetos experimentais abertos est\u00e3o em andamento. Como parte da iniciativa ModernFW<\/a><\/noindex> , est\u00e1 sendo trabalhado na cria\u00e7\u00e3o de uma substitui\u00e7\u00e3o escal\u00e1vel e segura para os firmwares UEFI e BIOS. O projeto est\u00e1 em uma fase inicial de desenvolvimento, mas nesta fase j\u00e1 possui funcionalidades suficientes no prot\u00f3tipo proposto para organizar a inicializa\u00e7\u00e3o do n\u00facleo do sistema operacional. O projeto \u00e9 baseado nos trabalhos de TianoCore<\/a><\/noindex> (uma implementa\u00e7\u00e3o aberta do UEFI) e retorna as altera\u00e7\u00f5es ao upstream.<\/p>\n

O ModernFW tem como objetivo fornecer firmwares minimalistas adequados para uso em plataformas verticalmente integradas, como servidores para sistemas em nuvem. Nessas plataformas, n\u00e3o h\u00e1 necessidade de manter c\u00f3digo na firmware para garantir a compatibilidade retroativa e componentes de uso geral, t\u00edpicos dos firmwares tradicionais UEFI. A elimina\u00e7\u00e3o de c\u00f3digo desnecess\u00e1rio reduz o n\u00famero de vetores potenciais para ataques e erros, o que melhora a seguran\u00e7a e a efici\u00eancia. Isso inclui a remo\u00e7\u00e3o do suporte a tipos de dispositivos obsoletos e funcionalidades que podem ser executadas no contexto do sistema operacional. <\/p>\n

S\u00e3o mantidos apenas os drivers de dispositivos necess\u00e1rios e fornecido suporte m\u00ednimo para dispositivos emulados e virtuais. Sempre que poss\u00edvel, tarefas que podem ser executadas no n\u00edvel do sistema operacional s\u00e3o transferidas para o n\u00edvel do sistema operacional. Parte do c\u00f3digo \u00e9 compartilhada entre o firmware e o n\u00facleo do SO. \u00c9 fornecida uma configura\u00e7\u00e3o modular e personaliz\u00e1vel. O suporte a arquiteturas ainda \u00e9 limitado a sistemas x86-64, e at\u00e9 agora apenas o Linux \u00e9 suportado entre os sistemas operacionais inicializ\u00e1veis (suporte a outros SOs pode ser implementado se necess\u00e1rio).<\/p>\n

Ao mesmo tempo, a empresa Intel apresentou<\/noindex> projeto Cloud Hypervisor<\/a><\/noindex>, no qual foi feita uma tentativa de criar um hipervisor baseado em componentes
\ndo projeto conjunto Rust-VMM<\/a><\/noindex>, onde al\u00e9m da Intel, empresas como Alibaba, Amazon, Google e Red Hat tamb\u00e9m est\u00e3o envolvidas. O Rust-VMM \u00e9 escrito na linguagem Rust e permite a cria\u00e7\u00e3o de hipervisores espec\u00edficos para determinadas tarefas. O Cloud Hypervisor \u00e9 um desses hipervisores que fornece um monitor de m\u00e1quinas virtuais de alto n\u00edvel (VMM), funcionando em cima do KVM e otimizado para resolver problemas caracter\u00edsticos de sistemas em nuvem. No contexto dos interesses da Intel, a principal tarefa do Cloud Hypervisor \u00e9 o lan\u00e7amento de distribui\u00e7\u00f5es modernas do Linux usando dispositivos paravirtualizados baseados em virtio.<\/p>\n

O suporte \u00e0 emula\u00e7\u00e3o \u00e9 minimizado (a \u00eanfase \u00e9 na paravirtualiza\u00e7\u00e3o). Atualmente, apenas sistemas x86_64 s\u00e3o suportados, mas h\u00e1 planos para suportar AArch64 tamb\u00e9m. Para eliminar c\u00f3digo desnecess\u00e1rio e simplificar, a configura\u00e7\u00e3o de CPU, mem\u00f3ria, PCI e NVDIMM \u00e9 feita na fase de constru\u00e7\u00e3o. H\u00e1 uma possibilidade de migra\u00e7\u00e3o de m\u00e1quinas virtuais entre servidores. Entre as principais tarefas, destacam-se: alta responsividade, baixo consumo de mem\u00f3ria, alto desempenho e redu\u00e7\u00e3o de poss\u00edveis vetores para ataques.<\/p>\n
