[Qemu-devel] [Tracing][v4 PATCH 0/2] QMP Query interfaces for tracing

[Prerna Saxena]

This patch set introduces three QMP query interfaces for tracing :

* query-trace        : to list current contents of trace-buffer
* query-trace-events : to list all available trace-events with their 
                       state.
* query-trace-file   : to list currently set trace-file with its status.
