Subject: [RESEND][PATCH v3 0/7] perf/amd/ibs: Add Zen5 support
Date: Wed, 5 Feb 2025 06:05:40 +0000 [thread overview]
Message-ID: <20250205060547.1337-1-ravi.bangoria@amd.com> (raw)
IBS on Zen5:
- introduced Load Latency filtering capability.
- shows DTLB and page size information differently from prior generations.
Incorporate these changes into IBS kernel driver as well as perf tool.
Also include a perf unit-test to test IBS sample period constraints.
Patches are prepared on peterz/queue/perf/core (cffa473a06d2).
v2: https://lore.kernel.org/r/20241218121437.1717-1-ravi.bangoria@amd.com
v2->v3:
- The patch series to fix IBS sample period computation [1] is picked up
by Peter except the last patch which added unit test in perf tool.
Include it in this series instead of sending it independently.
- No changes otherwise.
