There are the two zcrypt ioctl trace events covering the entry and exit of an ioctl with crypto requests giving the overall runtime within the kernel. However, there is no way to figure out the time where a request is enqueued into the AP bus queue but not pushed into the firmware queue. Then there is no information about the runtime of an request during processing in the firmware. And finally some info about pulling the reply from the firmware and delivering it into user space is missing. This series is aiming to provide a way to collect measurements which can be used to cover these runtime information for each crypto request/reply. ==================== Signed-off-by: Heiko Carstens --- 5c02c74dd482e0fb6c303a7e781812c26f06bcb8
