Google ha annunciato i risultati dell'ottimizzazione AutoFDO (Auto-Feedback-Directed Optimization) per la compilazione del kernel Linux per la piattaforma Android. AutoFDO utilizza i risultati del profiling con informazioni sulla frequenza di esecuzione delle varie sezioni di codice per migliorare le prestazioni delle operazioni eseguite frequentemente. L'ottimizzazione AutoFDO \u00e8 stata implementata nella compilazione del kernel Linux 6.12 per Android 16 e 6.6 per Android 15, e sar\u00e0 inclusa nella compilazione del kernel 6.18 per Android 17. I profili delle prestazioni per AutoFDO sono stati generati sulla base dell'esecuzione di 100 applicazioni popolari del set C-Suite (Android App Compatibility Test Suite) e della simulazione dell'interazione dell'utente con queste applicazioni. <\/p>\n

In precedenza, l'ottimizzazione AutoFDO era stata gi\u00e0 applicata in Android per la compilazione di librerie di sistema e file eseguibili nello spazio utente, consentendo in media di accelerare l'avvio dei programmi del 4% e di ridurre il tempo di caricamento dell'1%. Tuttavia, fino a poco tempo fa, l'ottimizzazione AutoFDO non era stata applicata al kernel Linux, per il quale, secondo le statistiche di Google, viene impiegato il 40% del tempo di CPU in Android. <\/p>\n

Nei test condotti, l'inclusione di AutoFDO per il kernel ha portato a una riduzione del tempo di avvio del 2.1%, a un'accelerazione del primo avvio dei programmi del 4.3%, a un aumento dell'efficienza delle chiamate di sistema del 9.3%, a una diminuzione del tempo di esecuzione delle transazioni mmap su Binder del 12.3%, su HwBinder del 20% e su Binder RPC del 21.7%.
