Subject: [PATCH 0/4] tools perf: Add branch speculation info
Date: Thu, 11 Aug 2022 18:16:45 +0530	[thread overview]
Message-ID: <cover.1660217326.git.sandipan.das@amd.com> (raw)

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:
https://lore.kernel.org/all/cover.1660211399.git.sandipan.das@amd.com/

  tools headers uapi: Sync perf_event.h with kernel sources
  tools headers x86: Sync msr-index.h with kernel sources
