Je travaille sur Android pour Raspberry Pi 3. Et je suis en train de réaliser un test de fio avec la commande suivante:FIO se termine avec une erreur de bus
$ fio --bs=4k --scramble_buffers=1 --direct=1 --loops=3 --numjobs=4 --filename=/dev/block/ram0 --name=rand-readwrite --rw=randrw --stonewall
dispositif exact que je suis en train de tester sur n'est pas si important pour le moment (courant est RAM), parce que le test de fio échoue sur n'importe quel appareil avec "erreur de bus". J'ai découvert que le problème est l'alignement de la mémoire. Comment peut-il être réparé?
Voici le journal strace:
