Hi
PEBS via PT is a new feature that encodes PEBS events into the Intel PT trace.
This patch series is preparation. Alex has posted his kernel support:
https://lkml.org/lkml/2019/5/2/323
This patch set adds the packet definitions and a new packet decoder test,
followed by patches that enable synthesizing PEBS samples.
