Drew DeVault a prezentat noul s\u0103u proiect \u2013 microkernelul Helios. \u00cen stadiul actual, proiectul se afl\u0103 \u00een faza incipient\u0103 de dezvoltare \u0219i suport\u0103 deocamdat\u0103 doar \u00eenc\u0103rcarea demonstrativ\u0103 pe sisteme cu arhitectur\u0103 x86_64. \u00cen viitor, se preconizeaz\u0103 implementarea suportului pentru arhitecturile iscv64 \u0219i aarch64. Codul proiectului este scris \u00eentr-un limbaj de programare de sistem similar cu C, numit Hare, cu inser\u021bii de asamblare, \u0219i este distribuit sub licen\u021ba GPLv3. Pentru a lua contact cu starea dezvolt\u0103rii, a fost preg\u0103tit un fi\u0219ier ISO de test (1 MB). <\/p>\n

Arhitectura Helios este construit\u0103 av\u00e2nd \u00een vedere conceptele microkernel-ului seL4, \u00een care componentele pentru gestionarea resurselor nucleului sunt mutate \u00een spa\u021biul utilizatorului, iar acelea\u0219i metode de separare a accesului sunt aplicate \u0219i pentru resursele utilizatorului. Microkernel-ul ofer\u0103 mecanisme minime pentru gestionarea accesului la spa\u021biul de adres\u0103 fizic, la \u00eentreruperi \u0219i la resursele procesorului, \u00een timp ce abstrac\u021biile de nivel \u00eenalt pentru driverele de interac\u021biune cu hardware-ul sunt implementate separat, deasupra microkernel-ului, sub form\u0103 de sarcini care ruleaz\u0103 la nivelul utilizatorului. <\/p>\n

Helios utilizeaz\u0103 un model de control al accesului bazat pe \"capability\". Kernelul ofer\u0103 primitivuri pentru alocarea paginilor de memorie, reflectarea memoriei fizice \u00een spa\u021biul de adresare, gestionarea sarcinilor \u0219i procesarea apelurilor c\u0103tre porturile dispozitivelor hardware. Pe l\u00e2ng\u0103 serviciile kernelului, precum gestionarea memoriei virtuale, proiectul a preg\u0103tit \u0219i drivere pentru operarea consolei prin portul serial \u0219i API-ul BIOS VGA. \u00cen etapa urm\u0103toare de dezvoltare a kernelului, se vor asigura func\u021bionalit\u0103\u021bi de multitasking preemptiv, IPC, PCI, procesarea excep\u021biilor, analiza tabelelor ACPI \u0219i gestionarea \u00eentreruperilor, care vor func\u021biona \u00een spa\u021biul utilizatorului. Pe termen lung, se planific\u0103 implementarea suportului pentru SMP, IOMMU \u0219i VT-x. <\/p>\n

\u00cen ceea ce prive\u0219te spa\u021biul utilizatorului, planurile includ dezvoltarea serviciilor de nivel sc\u0103zut \u0219i a managerului de sistem Mercury, a stratului de compatibilitate cu POSIX (Luna), a colec\u021biei de drivere Venus, a mediului pentru dezvoltatori Gaia \u0219i a framework-ului pentru testarea kernelului Vulcan. Dezvoltarea se desf\u0103\u0219oar\u0103 cu privire la utilizarea pe hardware real \u2013 \u00een etapa ini\u021bial\u0103, se preconizeaz\u0103 crearea de drivere pentru ThinkPad, inclusiv drivere pentru GPU Intel HD, HD Audio \u0219i Intel Gigabit Ethernet. Ulterior, se a\u0219teapt\u0103 apari\u021bia driverelor pentru GPU AMD \u0219i pl\u0103ci Raspberry Pi. <\/p>\n

Scopul final al proiectului este crearea unui sistem de operare complet Ares, cu un sistem de gestionare a pachetelor \u0219i o interfa\u021b\u0103 grafic\u0103 proprii. Motivul pentru care a fost creat proiectul este men\u021bionat dorin\u021ba de a experimenta \u0219i de a lucra ca o form\u0103 de divertisment (principiul \u201ejust for fun\u201d). Drew DeVolt \u00eei place s\u0103 \u00ee\u0219i stabileasc\u0103 obiective ambi\u021bioase \u0219i apoi, \u00een ciuda scepticismului general, s\u0103 le realizeze. A fost cazul cu mediu de utilizator Sway, clientul de email Aerc, platforma de dezvoltare colaborativ\u0103 SourceHut \u0219i limbajul de programare Hare. Dar chiar dac\u0103 noul proiect nu va c\u00e2\u0219tiga o popularitate adecvat\u0103, acesta va servi drept punct de plecare pentru dezvoltarea de noi sisteme utile. De exemplu, debuggerul dezvoltat pentru Helios este planificat s\u0103 fie portat pe platforma Linux, iar bibliotecile pentru construirea interfe\u021bei grafice nu vor fi legate de platform\u0103.
