[PATCH v2 3/3] platform/mellanox: mlxbf-pmc: Add support for BlueField-3
From: Shravan Kumar Ramani
Date: Thu Aug 31 2023 - 07:06:53 EST
Add new access mechanism and list of supported events to program
and read the counters in BlueField-3.
Performance counter blocks being added for BlueField-3 include:
- Memory Sub-system (mss) which has counters for monitoring
various DRAM and related skylib events
- Last level Tile, which has 2 sets of counters (llt, llt_miss)
for monitoring Tile and cache metrics
