Google a pr\u00e9sent\u00e9 les r\u00e9sultats de l'int\u00e9gration de l'optimisation AutoFDO (Optimisation dirig\u00e9e par retour automatique) lors de la compilation du noyau Linux pour la plateforme Android. AutoFDO utilise les r\u00e9sultats du profilage avec des informations sur la fr\u00e9quence d'ex\u00e9cution de diff\u00e9rentes sections de code afin d'am\u00e9liorer les performances des op\u00e9rations souvent ex\u00e9cut\u00e9es. L'optimisation AutoFDO est int\u00e9gr\u00e9e lors de la compilation du noyau Linux 6.12 pour Android 16 et 6.6 pour Android 15, et sera \u00e9galement incluse lors de la compilation du noyau 6.18 pour Android 17. Les profils de performance pour AutoFDO sont bas\u00e9s sur l'ex\u00e9cution de 100 applications populaires du jeu de tests C-Suite (Android App Compatibility Test Suite) et sur la simulation de l'interaction de l'utilisateur avec ces applications. <\/p>\n

Auparavant, l'optimisation AutoFDO avait d\u00e9j\u00e0 \u00e9t\u00e9 utilis\u00e9e dans Android lors de la compilation des biblioth\u00e8ques syst\u00e8me et des fichiers ex\u00e9cutables dans l'espace utilisateur, permettant en moyenne d'acc\u00e9l\u00e9rer le d\u00e9marrage des programmes de 4 % et de r\u00e9duire le temps de chargement de 1 %. Cependant, jusqu'\u00e0 r\u00e9cemment, l'optimisation AutoFDO n'avait pas \u00e9t\u00e9 appliqu\u00e9e au noyau Linux, qui, selon les statistiques de Google, consomme 40 % du temps processeur sous Android. <\/p>\n

Dans les tests effectu\u00e9s, l'activation de l'AutoFDO pour le noyau a conduit \u00e0 une r\u00e9duction du temps de d\u00e9marrage de 2,1 %, \u00e0 une acc\u00e9l\u00e9ration du premier lancement des programmes de 4,3 %, \u00e0 une augmentation de l'efficacit\u00e9 des appels syst\u00e8me de 9,3 %, \u00e0 une r\u00e9duction du temps d'ex\u00e9cution des transactions mmap de Binder de 12,3 %, de HwBinder de 20 % et de Binder RPC de 21,7 %.
