Po 8 mesiacoch v\u00fdvoja bol zverejnen\u00fd prv\u00fd prototyp Unix-podobn\u00e9ho jadra Moss, \u010diasto\u010dne kompatibiln\u00e9ho s Linuxom. K\u00f3d je nap\u00edsan\u00fd v jazyku Rust s assemblerov\u00fdmi vlo\u017ekami a \u0161\u00edri sa pod licenciou MIT. V s\u00fa\u010dasnosti projekt podporuje iba architekt\u00faru Aarch64, m\u00f4\u017ee sa sp\u00fa\u0161\u0165a\u0165 v QEMU a bol otestovan\u00fd na dosk\u00e1ch Raspberry Pi 4, Jetson Nano, AMD Kria a imx8. Pod\u013ea tvrden\u00ed v\u00fdvoj\u00e1rov je jadro \u013eahko prenosite\u013en\u00e9 na in\u00e9 architekt\u00fary, ako s\u00fa x86_64 a RISC-V, v\u010faka vrstve na abstrahovanie podpory hardv\u00e9ru. <\/p>\n
V tejto f\u00e1ze v\u00fdvoja implementoval Moss 51 syst\u00e9mov\u00fdch volan\u00ed Linuxu a zabezpe\u010dil bin\u00e1rnu kompatibilitu s aplik\u00e1ciami pre Linux, dostato\u010dn\u00fa na sp\u00fa\u0161\u0165anie pr\u00edkazov\u00e9ho shellu Bash a v\u00e4\u010d\u0161iny util\u00edt zo sady BusyBox. Medzi charakteristiky architekt\u00fary Moss patr\u00ed pou\u017eitie modelu async\/await na zabezpe\u010denie asynchr\u00f3nneho vykon\u00e1vania komponentov jadra, \u010d\u00edm sa vylu\u010duj\u00fa hlavn\u00e9 triedy vz\u00e1jomn\u00fdch blokovan\u00ed.

Hlavn\u00e9 mo\u017enosti: <\/p>\n

Syst\u00e9m spr\u00e1vy pam\u00e4te s podporou str\u00e1n pam\u00e4te v re\u017eime CoW (Copy-on-Write), tabuliek str\u00e1n pam\u00e4te, asynchr\u00f3nnych funkci\u00ed kop\u00edrovania pam\u00e4te medzi jadrom a priestorom pou\u017e\u00edvate\u013ea, spracovania v\u00fdnimiek (page fault) na strane jadra a priestore pou\u017e\u00edvate\u013ea.\n
Syst\u00e9m spr\u00e1vy procesov s pl\u00e1nova\u010dom \u00faloh a podporou migr\u00e1cie \u00faloh cez IPI (inter-processor interrupt). Podpora vetvenia procesov cez volanie clone(). Mo\u017enosti na doru\u010dovanie sign\u00e1lov procesom a vl\u00e1knam.\n
Asynchr\u00f3nne pracuj\u00faca vrstva VFS (Virtual File System), blokov\u00e9 zariadenie Ramdisk, ovl\u00e1da\u010d FAT32 a zariadenie devtmpfs.\n
Presun hlavnej funk\u010dnosti do kni\u017enice libkernel, ktor\u00e1 nie je viazan\u00e1 na hardv\u00e9rov\u00e9 architekt\u00fary.\n
HAL-vrstva (Hardware Abstraction Layer) na zabezpe\u010denie podpory hardv\u00e9ru.\n
Testovac\u00ed bal\u00edk, ktor\u00fd obsahuje viac ako 230 testov. <\/ul>\n
Medzi v\u00fdrazn\u00e9 obmedzenia patr\u00ed absencia sie\u0165ov\u00e9ho subsyst\u00e9mu a existenciu len ok\u00fasenej s\u00fa\u010dasti ovl\u00e1da\u010da s\u00faborov\u00e9ho syst\u00e9mu, podporuj\u00facej s\u00faborov\u00fd syst\u00e9m Fat32 v re\u017eime iba na \u010d\u00edtanie.
