Dans le cadre de cette initiative, <noindex><a rel=\"nofollow\" href=\"https:\/\/github.com\/intel\/ModernFW\">ModernFW<\/a><\/noindex> le travail est en cours pour cr\u00e9er un remplacement \u00e9volutif et s\u00e9curis\u00e9 des firmwares UEFI et BIOS. Le projet en est \u00e0 ses d\u00e9buts, mais \u00e0 ce stade de d\u00e9veloppement, le prototype propos\u00e9 dispose d\u00e9j\u00e0 de suffisamment de fonctionnalit\u00e9s pour organiser le d\u00e9marrage du noyau du syst\u00e8me d'exploitation. Ce projet est bas\u00e9 sur les travaux de <noindex><a rel=\"nofollow\" href=\"https:\/\/www.tianocore.org\/\">TianoCore<\/a><\/noindex> (une implementation open source de l'UEFI) et renvoie les modifications en amont.<\/p>\n<p>ModernFW vise \u00e0 fournir des firmwares minimalistes adapt\u00e9s aux plateformes int\u00e9gr\u00e9es verticalement, comme les serveurs pour syst\u00e8mes cloud. Sur de tels syst\u00e8mes, il n'est pas n\u00e9cessaire de maintenir dans le firmware du code pour assurer la r\u00e9trocompatibilit\u00e9 et des composants pour un usage universel, caract\u00e9ristiques des firmwares UEFI traditionnels. L'\u00e9limination du code superflu r\u00e9duit le nombre de vecteurs d'attaque et d'erreurs possibles, ce qui am\u00e9liore la s\u00e9curit\u00e9 et l'efficacit\u00e9. En particulier, un travail est en cours pour retirer du firmware le soutien aux types d'appareils obsol\u00e8tes et aux fonctionnalit\u00e9s qui peuvent \u00eatre ex\u00e9cut\u00e9es dans le contexte du syst\u00e8me d'exploitation. <\/p>\n<p>Seuls les pilotes d'appareils n\u00e9cessaires sont conserv\u00e9s et un support minimal pour les appareils \u00e9mul\u00e9s et virtuels est fourni. Si possible, les t\u00e2ches pouvant \u00eatre effectu\u00e9es au niveau du syst\u00e8me d'exploitation sont transf\u00e9r\u00e9es au niveau du syst\u00e8me d'exploitation. Une partie du code est partag\u00e9e entre le firmware et le noyau du syst\u00e8me d'exploitation. Une configuration modulaire et personnalisable est fournie. Le support des architectures est actuellement limit\u00e9 aux syst\u00e8mes x86-64, et parmi les syst\u00e8mes d'exploitation pouvant \u00eatre charg\u00e9s, seul Linux est support\u00e9 (le support d'autres syst\u00e8mes d'exploitation peut \u00eatre mis en \u0153uvre si n\u00e9cessaire).<\/p>\n<p>En m\u00eame temps, Intel <noindex>pr\u00e9sent\u00e9e<\/noindex> le projet <noindex><a rel=\"nofollow\" href=\"https:\/\/github.com\/intel\/cloud-hypervisor\">Cloud Hypervisor<\/a><\/noindex>, dans le cadre duquel une tentative a \u00e9t\u00e9 faite pour cr\u00e9er un hyperviseur bas\u00e9 sur les composants<br \/>\ndu projet conjoint <noindex><a rel=\"nofollow\" href=\"https:\/\/github.com\/rust-vmm\">Rust-VMM<\/a><\/noindex>, mettant en avant des entreprises comme Alibaba, Amazon, Google et Red Hat en plus d'Intel. Rust-VMM est \u00e9crit en Rust et permet de cr\u00e9er des hyperviseurs sp\u00e9cifiques \u00e0 certaines t\u00e2ches. Cloud Hypervisor est l'un de ces hyperviseurs, fournissant un moniteur virtuel de machines (VMM) de haut niveau, fonctionnant au-dessus de KVM et optimis\u00e9 pour les t\u00e2ches propres aux syst\u00e8mes cloud. Dans le cadre des int\u00e9r\u00eats d'Intel, l'objectif principal de Cloud Hypervisor est de faire fonctionner des distributions modernes de Linux en utilisant des p\u00e9riph\u00e9riques paravirtualis\u00e9s bas\u00e9s sur virtio.<\/p>\n<p>Le support de l'\u00e9mulation est r\u00e9duit au minimum (l'accent \u00e9tant mis sur la paravirtualisation). Actuellement, seuls les syst\u00e8mes x86_64 sont pris en charge, mais un support pour AArch64 est pr\u00e9vu. Pour \u00e9liminer le code superflu et simplifier la configuration, le CPU, la m\u00e9moire, le PCI et le NVDIMM sont configur\u00e9s lors de la construction. La migration des machines virtuelles entre les serveurs est possible. Parmi les objectifs cl\u00e9s figurent : une grande r\u00e9activit\u00e9, une faible consommation de m\u00e9moire, une haute performance et la r\u00e9duction des vecteurs possibles pour les attaques.<\/p>\n<p><noindex><a rel=\"nofollow\" name=\"link\"><\/a><\/noindex><\/p>\n<p>Source : <a \ncontent=\"nofollow\" rel=\"nofollow\"
