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.
Ravi Bangoria (8):
perf test amd ibs: Fix incorrect kernel version check
perf tool ibs: Sync AMD IBS header file
perf test ibs: Skip privilege test on Zen6 and newer platforms
perf amd ibs: Suppress bogus TlbRefillLat and DCPhysAd on Zen4+
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
perf doc: Document new IBS capabilities in man page
