Hi Greg, >That's great, but what are these "events"? Trace data? Debugging stuff? Or "real" data that userspace > >needs to do something with? These are instrumentation events that give information on what is going on inside the driver. They are emitted as a stream if requested by a user mode application and consumed by that application. They are not needed for the normal operation of the device but are very useful during debugging and checking the driver is behaving correctly. The whole subsystem can be optionally removed in at compile time.
