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).
