64 Up until this point no decoding of the SPE data was done by either the kernel or Perf. Only when the

69 just the instruction pointer, but an SPE sample can have data addresses and latency attributes.
84 However, SPE does not provide any call-graph information, and relies on statistical methods.

122 You can record a session with SPE samples:
