Subject: [RFC PATCH v3 0/6] TPEBS counting mode support

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

Changes in v3:
- Remove ':' when event name has '@' [Ian]
- Use 'R' as the modifier instead of "retire_latency" [Ian]

v2: https://lore.kernel.org/all/20240228161227.484886-1-weilin.wang@intel.com/

Weilin Wang (6):
  perf stat: Parse and find tpebs events when parsing metrics to prepare
    for perf record sampling
  perf 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: Create another thread for sample data processing
  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
