Subject: [PATCH 0/6] perf tools amd ibs: Fixes + future enhancements
Date: Mon, 19 Jan 2026 02:43:21 +0000	[thread overview]
Message-ID: <20260119024328.897-1-ravi.bangoria@amd.com> (raw)

o Drop perf unit test that assumes IBS don't have hardware-assisted
  privilege filter. This is now supported.
o Starting with Zen4, the validity of several IBS fields changes. Add
  the required dependency checks when decoding IBS MSRs.
o Future CPUs extend IBS OP with Streaming-Store and Remote-Socket
  indicators for load/store instructions. Add decoding support for
  these new bits.

Patches are prepared on perf-tools-next/perf-tools-next (571d29baa07e).

  perf tool ibs: Sync AMD IBS header file

  perf amd ibs: Make Fetch status bits dependent on PhyAddrValid for
    newer platforms
  perf amd ibs: Decode Remote-Socket flag in IBS OP raw dump
  perf amd ibs: Decode Streaming-store flag in IBS OP raw dump
