To display the currently used Intel(R) Processor Trace (Intel(R) PT) configuration, use the !showconfig command. This prints a table of all the relevant model-specific registers (MSRs) that make up the Intel(R) PT configuration. After that, the extension prints a human-readable interpretation of that raw data, like, for example, Tracing is enabled.

Following is an example output on a target machine with two processors:
