7 Intel Processor Trace (Intel PT) is an extension of Intel Architecture that
13 Intel PT is first supported in Intel Core M and 5th generation Intel Core
30 The main distinguishing feature of Intel PT is that the decoder can determine
31 the exact flow of software execution. Intel PT can be used to understand why
33 software does not have to be recompiled, so Intel PT works with debug or release
38 A limitation of Intel PT is that it produces huge amounts of trace data
51 The simplest thing to do with Intel PT is userspace profiling of small programs.
85 Also note that the coarseness of Intel PT timing information will start to
116 Refer to 'new snapshot option' and 'Intel PT modes of operation' further below.
134 The Intel PT kernel driver creates a new PMU for Intel PT. PMU events are
189 'h', 'G' and 'H' are for virtualization which is not supported by Intel PT.
190 'p' is also not relevant to Intel PT. So only options 'u' and 'k' are
191 meaningful for Intel PT.
221 Manuals, Chapter 36 Intel Processor Trace, defined new Intel PT features.
433 Intel PT snapshot size: %zu
439 Intel PT buffer size is specified by an addition to the -m option e.g.

472 Intel PT can be used in 2 modes:
