v1.4.1

Bugs Fixed:

• The previous release added this feature: Support for AWS m6i.16xlarge, m6i.32xlarge, and m7i.*xlarge VM instances. The metric definition files for these instance types were not included in the release build. This release addresses that issue, i.e., the files are now included in the build.

v1.4.0

New Features / Improvements

• Support for 6th-generation Intel Xeon processors (Sierra Forest)
• Support for AWS m6i.16xlarge, m6i.32xlarge, and m7i.*xlarge VM instances.
• Allow running perf-collect as regular, non-root, user without sudo. See system configuration requirements in the README.
• Add options to override default event and metric files used by perf-collect and perf-postprocess respectively.
• Support platforms where enumeration of uncore device IDs does not start at 0.
• Add detection and logging of fixed purpose PMU slots, e.g. cpu-cycles, instructions, etc., availability.
