Ubuntu on otsustanud vaikimisi kasutada intel-compute-runtime paketti, mis on loodud NEO_DISABLE_MITIGATIONS lipuga, mis keelab Spectre r\u00fcnnakute kaitse. Ubuntu arendajate hinnangul toob selline kaitse paketi j\u00f5udluse umbes 20% v\u00e4henemise. <\/p>\n

Intel-compute-runtime pakett sisaldab komponente, mis on vajalikud OpenCL-i ja OneAPI Level Zero kasutamiseks Intel GPU-del. Paketi kohandatud raamatukogude koostamise ajal viib NEO_DISABLE_MITIGATIONS koonduslipp kompilatoris valikute «-mretpoline -mindirect-branch=thunk -mfunction-return=thunk -mindirect-branch-register» keelamiseni, mis pakuvad t\u00e4iendavat kaitset Spectre'i eest. Need valikud ei m\u00f5juta OpenCL-i ja GPU-l toimuvate operatsioonide j\u00f5udlust, kuid v\u00e4hendavad vajadust API t\u00f6\u00f6 eest vastutava koodi t\u00e4itmise kulude \u00fcle. <\/p>\n

Intel ja Canonicali turvainsenerid j\u00f5udsid arutelu k\u00e4igus j\u00e4reldusele, et Compute Runtime tasemel rakendatud Spectre kaitse pole enam vajalik, kuna vajalik kaitse on juba olemas tuuma tasemel. Compute Runtime'i Spectre kaitse pakub huvi peamiselt neile, kes kasutavad tuumasid, millel pole korralikku kaitset, ja selle kasu ei tasu \u00fcles vaatatud j\u00f5udluse v\u00e4henemist. Lisaks sellele on Intel Graphics Compute Runtime'i v\u00e4ljaanded koostatud vaikimisi NEO_DISABLE_MITIGATIONS lipuga, mis keelab kaitse.
