Trying to get iotop working and udoo is the first development board ( raspberry pi , cubieboard , sheevaplug etc ) where it not worked out of the box by default. It saying :- I/O accounting support (CONFIG_TASKSTATS, CONFIG_TASK_DELAY_ACCT, CONFIG_TASK_IO_ACCOUNTING) I made my first kernel for the udoo last night and just used the default UDOO_defconfig and compiled that without any changes , so no problem if it just a add this problem. Looking at the .configure file I can see that CONFIG_TASKSTATS is not set , but can`t see any reference to CONFIG_TASK_DELAY_ACCT or CONFIG_TASK_IO_ACCOUNTING. Anyone got any clues how to get iotop working ?
