From: Kan Liang <kan.li...@linux.intel.com> Intel Sapphire Rapids server is the successor of the Intel Ice Lake server. There are several user-visible features introduced. - Two new data source fields, data block & address block, are added in the PEBS Memory Info Record for the load latency event. Improve the c2c and mem tools to display the reasons of a memory load block. - Support the new instruction latency in perf mem. Support the new sample type, PERF_SAMPLE_WEIGHT_STRUCT. - Support TMA method level 2 metrics with the perf stat --topdown option. Update the topdown documentation accordingly.
The full description for the SPR features can be found at Intel Architecture Instruction Set Extensions and Future Features Programming Reference, 319433-041 (and later). The kernel patches has been merged into the tip:perf/core branch.
