From: Dapeng Mi <redacted>
Add memory region field to the cacheline list view to help users
identify the memory region to which the cacheline belongs. The memory
region field was included with the introduction of support for the
Off-module Response facility (OMR) [1] in Intel's Diamond Rapids and
Nova Lake architectures.
An example of the new perf c2c output including the memory region
field is shown below:
Shared Data Cache Line Table (181 entries, sorted on Total HITMs)
