Seems only a single event... Yes, actually it needs a single metric. I consult to Will before, there is no way to program it in the kernel. I also don't want users to enter a long command line, what worst is that users need find out the AXI ID for each master. If we put it in the metric, it is more friendly. Is it reasonable that a single metric could be regarded as a special metric?
