From: Kan Liang <kan.liang@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.
