Compania Intel a prezentat<\/a><\/noindex> la conferin\u021ba OSTS (Open Source Technology Summit) care se desf\u0103\u0219oar\u0103 \u00een aceste zile, c\u00e2teva noi proiecte experimentale deschise. \u00cen cadrul ini\u021biativei ModernFW<\/a><\/noindex> se lucreaz\u0103 la crearea unei \u00eenlocuiri scalabile \u0219i sigure pentru firmware-urile UEFI \u0219i BIOS. Proiectul este \u00een stadiul incipient de dezvoltare, dar la acest stadiu de dezvoltare, prototipul propus are deja suficiente capacit\u0103\u021bi pentru a organiza \u00eenc\u0103rcarea nucleului sistemului de operare. Proiectul se bazeaz\u0103 pe realiz\u0103rile TianoCore<\/a><\/noindex> (o implementare deschis\u0103 a UEFI) \u0219i returneaz\u0103 modific\u0103rile c\u0103tre upstream.<\/p>\n

ModernFW este destinat oferirii de firmware-uri minimaliste, adecvate pentru utilizarea pe platforme vertical integrate, cum ar fi servere pentru sisteme cloud. Pe astfel de sisteme nu exist\u0103 nevoie de a men\u021bine \u00een firmware cod pentru asigurarea compatibilit\u0103\u021bii \u00eenapoi \u0219i componente pentru utilizare universal\u0103, caracteristice firmware-urilor tradi\u021bionale UEFI. Eliminarea codului neutilizat reduce num\u0103rul posibilit\u0103\u021bilor de atacuri \u0219i erori, ceea ce are un impact pozitiv asupra securit\u0103\u021bii \u0219i eficien\u021bei. De asemenea, se lucreaz\u0103 la eliminarea din firmware a suportului pentru tipuri de dispozitive \u0219i func\u021bionalit\u0103\u021bi \u00eenvechite, care pot fi executate \u00een contextul sistemului de operare. <\/p>\n

Au fost p\u0103strate doar driverele necesare ale dispozitivelor \u0219i s-a oferit suport minim pentru dispozitivele emulate \u0219i virtuale. C\u00e2nd este posibil, sarcinile care pot fi executate la nivel de sistem de operare sunt mutate la nivelul sistemului de operare. O parte din codul este utilizat \u00een comun \u00een firmware \u0219i nucleul sistemului de operare. Se ofer\u0103 o configura\u021bie modular\u0103 \u0219i personalizabil\u0103. Suportul pentru arhitecturi este pentru moment limitat la sistemele x86-64, iar din sistemele de operare bootabile este sus\u021binut doar Linux (dac\u0103 este necesar, poate fi implementat \u0219i suportul pentru alte sisteme de operare).<\/p>\n

\u00cen acela\u0219i timp, compania Intel a prezentat<\/noindex> proiect Cloud Hypervisor<\/a><\/noindex>, \u00een cadrul c\u0103ruia a fost \u00eentreprins\u0103 o \u00eencercare de a crea un hypervisor pe baza componentelor
\nproiectului comun Rust-VMM<\/a><\/noindex>, \u00een care, pe l\u00e2ng\u0103 Intel, particip\u0103 \u0219i companiile Alibaba, Amazon, Google \u0219i Red Hat. Rust-VMM este scris \u00een limbajul Rust \u0219i permite crearea de hypervisoare specifice pentru anumite sarcini. Cloud Hypervisor este unul dintre aceste hypervisoare, care ofer\u0103 un monitor virtual de ma\u0219ini (VMM) de nivel \u00eenalt, care func\u021bioneaz\u0103 deasupra KVM \u0219i este optimizat pentru a rezolva sarcini specifice sistemelor de tip cloud. \u00cen contextul intereselor Intel, sarcina principal\u0103 a Cloud Hypervisor este rularea distribu\u021biilor moderne Linux utiliz\u00e2nd dispozitive paravirtualizate bazate pe virtio.<\/p>\n

Suportul pentru emulare a fost minimizat (focaliz\u00e2ndu-se pe paravirtualizare). \u00cen prezent, sunt acceptate doar sistemele x86_64, dar sunt planificate \u0219i suportul pentru AArch64. Pentru a elimina codul inutil \u0219i a simplifica configurarea, procesorul, memoria, PCI \u0219i NVDIMM sunt configurate \u00een etapa de construc\u021bie. Este prev\u0103zut\u0103 posibilitatea migra\u021biei ma\u0219inilor virtuale \u00eentre servere. Dintre principalele sarcini men\u021bionate: reac\u021bie rapid\u0103, consum redus de memorie, performan\u021b\u0103 ridicat\u0103 \u0219i reducerea posibilelor vectori pentru atacuri.<\/p>\n
