[weilin.wang@intel.com]

From: Weilin Wang <weilin.wang@intel.com>

Changes in v7:
- Update code and comments for better code quality [Namhyung]
- Add a separate commit for perf data [Namhyung]
- Update retire latency print function to improve alignment [Namhyung]

v6: https://lore.kernel.org/all/20240329191224.1046866-1-weilin.wang@intel.com/

Weilin Wang (6):
  perf stat: Parse and find tpebs events when parsing metrics to prepare
    for perf record sampling
  perf data: Allow to use given fd in data->file.fd
  perf stat: Fork and launch perf record when perf stat needs to get
    retire latency value for a metric.
  perf stat: Add retire latency values into the expr_parse_ctx to
    prepare for final metric calculation
  perf stat: Add retire latency print functions to print out at the very
    end of print out
  perf vendor events intel: Add MTL metric json files
