[Ian Rogers]

This series contains the final remaining unmerged patch for the perf test
improvements sent as v8 in:
https://lore.kernel.org/lkml/20260602174129.3192312-1-irogers@xxxxxxxxxx/

v9 Changes
----------
- Patch 1: Resubmitted the "perf pmu: Recognize 'default_core' as a core PMU..."
  patch, but this time with a squashed fix for a metric resolution bug due to
  its use of is_pmu_core.
- Patch 2: Added explicit clamping for max_desc_width and width based on the
  buffer size in format_test_description() to satisfy GCC 16 and prevent the
  -Wformat-truncation warning reported by the maintainer.

Ian Rogers (2):
  perf pmu: Recognize 'default_core' as a core PMU and document matching
  perf test: Truncate printed test descriptions dynamically to avoid
    terminal wrapping
