Drew DeVault har presenterat sitt nya projekt \u2013 mikrok\u00e4rnan Helios. I sin nuvarande form \u00e4r projektet i ett tidigt utvecklingsskede och st\u00f6djer f\u00f6r n\u00e4rvarande endast en demonstrationsstart p\u00e5 system med x86_64-arkitektur. I framtiden planeras st\u00f6d f\u00f6r arkitekturerna iscv64 och aarch64. Projektets kod \u00e4r skriven i ett C-liknande systemprogrammeringsspr\u00e5k kallat Hare, med assemblerinslag och distribueras under GPLv3-licensen. F\u00f6r att ge en inblick i utvecklingsstatus har en test-ISO-bild (1 MB) tagits fram. <\/p>\n

Helios-arkitekturen \u00e4r byggd med h\u00e4nsyn till koncepten kring mikro-k\u00e4rnan seL4, d\u00e4r komponenterna f\u00f6r resursf\u00f6rvaltning har flyttats till anv\u00e4ndarutrymmet och samma \u00e5tkomstkontrollmedel till\u00e4mpas som f\u00f6r anv\u00e4ndarresurser. Mikro-k\u00e4rnan tillhandah\u00e5ller minimala mekanismer f\u00f6r att hantera \u00e5tkomst till det fysiska adressutrymmet, avbrott och processorr kaynaklar, medan h\u00f6gre abstraktioner av drivrutiner f\u00f6r interaktion med h\u00e5rdvara implementeras separat ovanp\u00e5 mikro-k\u00e4rnan i form av uppgifter som k\u00f6rs p\u00e5 anv\u00e4ndarniv\u00e5. <\/p>\n

I Helios anv\u00e4nds en \u00e5tkomstreferensmodell baserad p\u00e5 \"capability\". K\u00e4rnan tillhandah\u00e5ller primitiva funktioner f\u00f6r att allokera minnessidor, spegla fysisk minne i adressutrymmet, hantera uppgifter och bearbeta anrop till h\u00e5rdvaruportar. F\u00f6rutom kernels tj\u00e4nster som hantering av virtuell minne har projektet ocks\u00e5 f\u00f6rberett drivrutiner f\u00f6r att arbeta med konsolen via seriell port och BIOS VGA API. I n\u00e4sta utvecklingsfas kommer k\u00e4rnan att s\u00e4kerst\u00e4lla tidsdelad multitasking, IPC, PCI, undantagshantering, tolkning av ACPI-tabeller och avbrottshanterare som arbetar i anv\u00e4ndarutrymmet. P\u00e5 l\u00e4ngre sikt planeras st\u00f6d f\u00f6r SMP, IOMMU och VT-x. <\/p>\n

N\u00e4r det g\u00e4ller anv\u00e4ndarutrymmet finns det planer p\u00e5 att utveckla l\u00e5gniv\u00e5 tj\u00e4nster och systemchefer Mercury, ett kompatibilitetslager med POSIX (Luna), en samling av drivrutiner Venus, en milj\u00f6 f\u00f6r utvecklare Gaia, och ett ramverk f\u00f6r k\u00e4rntestning Vulcan. Utvecklingen sker med fokus p\u00e5 anv\u00e4ndning p\u00e5 verklig h\u00e5rdvara \u2013 i det tidiga skedet planeras skapandet av drivrutiner f\u00f6r ThinkPad, inklusive drivrutiner f\u00f6r Intel HD GPU, HD Audio och Intel Gigabit Ethernet. Efter det f\u00f6rv\u00e4ntas drivrutiner f\u00f6r GPU AMD och Raspberry Pi-kort. <\/p>\n

Det slutliga m\u00e5let f\u00f6r projektet \u00e4r att skapa ett fullfj\u00e4drat operativsystem Ares med sin egen paketchef och grafiska gr\u00e4nssnitt. Som anledning till projektets skapande n\u00e4mns en dragning till experiment och arbete som underh\u00e5llning (principen \"just for fun\"). Drew DeWalt \u00e4lskar att s\u00e4tta ambiti\u00f6sa m\u00e5l f\u00f6r sig sj\u00e4lv och f\u00f6rverkliga dem trots allm\u00e4n skepticism. Det var s\u00e5 det gick med anv\u00e4ndarmilj\u00f6n Sway, e-postklienten Aerc, plattformen f\u00f6r gemensam utveckling SourceHut och programmeringsspr\u00e5ket Hare. Men \u00e4ven om det nya projektet inte f\u00e5r tillr\u00e4cklig spridning, kommer det att fungera som en utg\u00e5ngspunkt f\u00f6r utvecklingen av nya anv\u00e4ndbara system. Till exempel planeras debuggan f\u00f6r Helios att porteras till Linux-plattformen, och biblioteken f\u00f6r att bygga grafiska gr\u00e4nssnitt kommer inte att vara knutna till n\u00e5gon specifik plattform.
