T\u00f6\u00f6riist on m\u00f5eldud Intel GPU j\u00f5udluse anal\u00fc\u00fcsi ja selle visuaalseks esitamiseks. Kood on kirjutatud C keeles ja avatud Apache 2.0 litsentsi alusel. <\/p>\n

Toetatud riistvaraplatvormide hulka kuuluvad Intel Arc graafikakaardid, mis p\u00f5hinevad mikroarhitektuuril Battlemage (seeria \"B\"), andmekeskuste GPU-d seerias \"Max\" ja erinevad graafikakaardid Intel Xe2, sealhulgas iGPU Lunar Lake-l. S\u00fcsteemis on vajalik Linuxi tuum, kus on v\u00e4rsked draiverid Intel GPU-de jaoks (Intel Battlemage jaoks on vajalik tuum 6.15 ja draiver Xe, aga Intel Max seeria jaoks piisab tuumast 5.15 ja draiverist i915). Linuxi tuum peab olema kompileeritud Intel'i draiveritega spetsiifiliste liideste EU Stall ja EU Debugga. <\/p>\n

Kogutud profiilides kajastuvad tehingud t\u00e4itev\u00fcksuste (Execution Unit) t\u00f6\u00f6 viivitustes, CPU seisundis ja GPU tuumade kohta k\u00e4ivas teabes. Kogutud andmed v\u00f5imaldavad seostada GPU j\u00f5udlusn\u00e4itajaid CPU-l k\u00e4idava koodiga. T\u00f6\u00f6riista on praktikas mugav kasutada m\u00e4ngude ja AI rakenduste j\u00f5udluse anal\u00fc\u00fcsimiseks, mis intensiivselt kasutavad GPU-d, v\u00f5rreldes GPU koormust OS-i tuuma, runtime-raamatukogude ja AI raamistikute komponentide CPU toimingutega. <\/p>\n

Profiliseerimistulemusi saab salvestada SVG-formaadis interaktiivseks anal\u00fc\u00fcsiks brauseris (n\u00e4ide), kasutades v\u00e4rvilisi diagramme \"FlameGraph\" ja kaarte \"FlameScope\", mis esitlevad probleemikohti v\u00e4rvide abil. Diagrammid on interaktiivsed ja v\u00f5imaldavad suurendada detailide hulka kuni k\u00e4skude virnade ja GPU t\u00e4idetud juhiste tasemeni, vaadata \u00fcksikasju ja teostada otsingutegevusi.
