From: Sandipan Das
Date: Thu Aug 11 2022 - 08:47:15 EST
AMD Last Branch Record Extension Version 2 (LbrExtV2) provides branch
speculation information and the perf UAPI is extended to provide this in a
generic manner. Update the tools headers and perf tool to be able to show
this additional information.
The LbrExtV2 enablement and UAPI changes can be found at:

tools headers uapi: Sync perf_event.h with kernel sources
tools headers x86: Sync msr-index.h with kernel sources
perf script: Show branch speculation info
