Avaldatud on katsed Linuxi k\u00e4ivitamise korraldamiseks 3D-virtuaalsetes ruumides mitme kasutaja online-m\u00e4ngus VRChat, mis v\u00f5imaldab 3D-mudeleid koos oma shader'itega. Teostatud idee jaoks loodi RISC-V arhitektuuri emulaator, mis t\u00f6\u00f6tab GPU poolel piksliliste (fragmentide) shader'itena (VRChat ei toeta arvutusshader'ite ja UAV-de kasutamist). Emulaatori kood on avaldatud MIT litsentsi alusel. <\/p>\n

Emulaatori aluseks on C keeles teostatud implementatsioon, mille loomisel on kasutatud minimalistliku emulaatori riscv-rust arengut, mis on arendatud Rust keeles. Valmistatud C-kood t\u00f5lgitakse HLSL keeles pikslisse shader'isse, mis sobib VRChat'i \u00fcles laadimiseks. Emulaator pakub t\u00e4ielikku toetust rv32imasu k\u00e4su komplektile, SV32 m\u00e4lu juhtplokile ja minimaalsele hulkale periferiaseadmeid (UART ja taimer). Valmistatud v\u00f5imalustega piisab Linux 5.13.5 tuuma ja BusyBox'i p\u00f5hik\u00e4skluste keskkonna \u00fcles laadimisest, millega saab otse virtuaalses maailma VRChat suhelda.
