[Qemu-devel] [PATCH 00/13] instrument: Add basic event instrumentation

[Lluís Vilanova]

This series adds a basic interface to instrument tracing events and control
their tracing state.

The instrumentation code is dynamically loaded into QEMU (either when it starts
or later using its remote control interfaces).

All events can be instrumented, but the instrumentable events must be explicitly
specified at configure time.
