This patch hooks tracepoints for the handoff point to/from hardware. With these tracepoints in place we can view the time between gb_message_send and usb_submit_urb and similarly we can view the time between cport_in_callback and gb_message_recv_response/gb_message_recv_request - trace_gb_host_device_send - trace_gb_host_device_recv It provides standard tracepoints at /sys/kernel/debug/tracing/events/greybus/gb_host_device_send /sys/kernel/debug/tracing/events/greybus/gb_host_device_recv Giving outputs like gb_host_device_recv: greybus:2-1 if_id=0000 l=10 gb_host_device_send: greybus:2-1 if_id=0000 l=10 Signed-off-by: Bryan O'Donoghue <bryan.odonoghue@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@google.com> |
