  "message": "ui/tp: Fix empty Linux perf flamegraph counter options (#6573)\n\nperfetto: Fix empty Linux perf flamegraph counter options\nPrevent empty counter metric options (like \"cpu-clock\" for software\nclock\nsources) from showing in the perf flamegraph dropdown when no counter\nvalues exist in the trace.\n\n- tp: Verify if the optional `timebase_count` field is present in the\n  protobuf perf_sample packet before calling `PushCounter`. This stops\n  writing dummy `0.0` counter entries to the database for software clock\n  sources.\n- ui: Update the pre-fetch query in `cacheCounterTypesPerSession` to\n  exclude counter tracks that do not have at least one non-zero counter\n  entry using a `WHERE EXISTS` check.\n- test: Added `test_perf_sample_timebase_count` diff test to assert that\n  sample packets with count fields populate counters, while packets\n  without do not.\n\nFixes: #6552",
