[PATCH 0/3] perf: marvell: LLC-TAD PMU MPAM filtering and CN20K support

From: Geetha sowjanya

Date: Sun Jun 07 2026 - 09:17:58 EST


This series extends the Marvell LLC-TAD performance driver used on CN10K
and CN20K systems.

Patch 1 adds optional MPAM partition-id filtering for the subset of TAD
events that support it, exposes a partid field in the PMU format string,
and keeps the reduced Odyssey event surface without advertising partid
where it does not apply.

Patch 2 introduces CN20K LLC-TAD support: non-standard PFC/PRF offsets,
additional programmable events, CN20K-specific MPAM encoding for the V3
profile, and device discovery via DeviceTree and ACPI.
