[PATCH v1 0/7] perf ui: Implement hybrid event merging for heterogeneous systems

[Ian Rogers <irogers@google.com>]

This series implements hybrid event merging internally inside the perf TUI 
and explicitly configures support for --hybrid-merge for both `perf top` 
and `perf report`. Introduce a `--hybrid-merge` command line flag (with a 
dynamic `'M'` hotkey mapped natively inside the `hists` browser) that 
collapses hybrid events visually together natively during histogram 
generation and sorts by the total. Add columns for each event.

Ian Rogers (7):
  perf evlist: Implement evlist__can_merge_hybrid using
    first_wildcard_match
  perf ui hist: Add support for aggregated total_period and merging
    entries cleanly
  perf ui browsers: Implement interactive 'M' keystroke to toggle hybrid
    event merging
  perf tools: Expose opt-in --hybrid-merge
  perf Documentation: Add tip for hybrid event merging
  perf ui hist: Format group headers iteratively based on proportional
    visual allocations
  perf test: Expand top tests for --hybrid-merge
