Subject: [PATCH v3 0/8] perf tools amd ibs: Fixes + Zen6 enhancements
Date: Fri, 8 May 2026 05:59:56 +0000	[thread overview]
Message-ID: <20260508060004.2575-1-ravi.bangoria@amd.com> (raw)

o Fix kernel version check in perf IBS unit test.
o On Zen6 and newer platforms, skip perf unit test that assumes IBS don't
  have hardware-assisted privilege filter.
o Starting with Zen4, the validity of several IBS fields changes. Add
  the required dependency checks when decoding IBS MSRs.
o Zen6 and future platforms extends IBS OP with Streaming-Store and
  Remote-Socket indicators for load/store instructions. Add decoding
  support for these new bits.
o Document new IBS features in perf-amd-ibs man page 

IBS Zen6 enhancements doc:
  AMD64 Zen6 Instruction Based Sampling (IBS) Extensions and Features,
  Pub. 69205 Rev. 1.00 March 2026 
  https://bugzilla.kernel.org/attachment.cgi?id=310002

Patches are prepared on perf-tools-next/perf-tools-next (53bc03289278).

v2: https://lore.kernel.org/r/20260430061115.10266-1-ravi.bangoria@amd.com  
v2->v3:
 - Instead of removing the priv modifier unit test completely, skip
   it on platforms that supports hardware privilege filtering. (Namhyung)
 - Rebased the series on latest perf-tools-next/perf-tools-next.
