Always +writes a markdown verdict block to stdout, suitable for piping into +`$GITHUB_STEP_SUMMARY`. + +Defaults: + --geomean-floor 0.97 (no more than 3% aggregate slowdown) + --kernel-floor 0.90 (no kernel may regress more than 10%) + --warn-floor 0.95 (soft-warn band for individual kernels in + [0.90, 0.95); 5-10% slower → advisory) + --max-cv 5.0 (skip kernels above this run-to-run noise) + +The per-kernel floor is set to a strict 10% regression because the +upstream workflow now builds both PR and main rustVX with EXPLICIT +AVX2 features and `-C target-cpu=x86-64-v3` (rather than per-VM +auto-detected features). With the binaries having identical +compile-time configuration and both running on the same Phase-3 +runner VM, the only remaining noise source is genuine same-VM +jitter (cache state, thermal, VM-host neighbour load), which on +real CI sits well below 10%. Anything that trips the gate is a +real regression worth investigating. + +Aggregate moves > 3% across 50+ verified kernels are essentially +impossible to fake with noise, which is why the geomean floor is +the strongest gate signal — it stays at 0.97x. + +Each filter is applied independently; a kernel that doesn't pass the +filters (unverified, noisy, missing on either side) is reported in a +"skipped" section but does not contribute to the gate decision. +""" + +from __future__ import annotations + +import argparse +import json +import math +import sys +from dataclasses import dataclass +from typing import Iterable + + +# --------------------------------------------------------------------------- +# Data shape +# --------------------------------------------------------------------------- + + +@dataclass +class Row: + name: str + mode: str + resolution: str + mps: float + sustained_ms: float + cv_percent: float + verified: bool + stability_warning: bool + + @property + def key(self) -> tuple[str, str, str]: + return (self.name, self.mode, self.resolution) + + +def _row_from(d: dict) -> Row: + wc = d.get("wall_clock", {}) or {} + return Row( + name=d.get("name", ""), + mode=d.get("mode", ""), + resolution=d.get("resolution", ""), + mps=float(d.get("megapixels_per_sec") or 0.0), + sustained_ms=float(d.get("sustained_ms") or 0.0), + cv_percent=float(wc.get("cv_percent") or 0.0), + verified=bool(d.get("verified", True)), + stability_warning=bool(d.get("stability_warning", False)), + ) + + +def _load(path: str) -> dict[tuple[str, str, str], Row]: + with open(path) as f: + report = json.load(f) + out: dict[tuple[str, str, str], Row] = {} + for r in report.get("results", []): + row = _row_from(r) + out[row.key] = row + return out + + +def _load_system(path: str) -> dict: + """Return the `system` block from a benchmark_results.json, or {}.""" + with open(path) as f: + report = json.load(f) + return report.get("system", {}) or {} + + +# --------------------------------------------------------------------------- +# Verdict +# --------------------------------------------------------------------------- + + +@dataclass +class KernelVerdict: + key: tuple[str, str, str] + main: Row + pr: Row + ratio: float # pr_mps / main_mps + status: str # "ok" | "warn" | "fail" + reason: str = "" + + +@dataclass +class SkipRecord: + key: tuple[str, str, str] + reason: str + # Carry the underlying rows when both sides are available, so the + # comprehensive "All kernels" table can still display the kernel's + # numbers (sorted alongside the gated kernels) even though the row + # itself does not contribute to the gate decision. + main: "Row | None" = None + pr: "Row | None" = None + + +def _classify( + main: Row, + pr: Row, + *, + kernel_floor: float, + warn_floor: float, +) -> KernelVerdict: + if main.mps <= 0 or pr.mps <= 0: + return KernelVerdict( + key=main.key, + main=main, + pr=pr, + ratio=0.0, + status="fail", + reason="zero throughput", + ) + ratio = pr.mps / main.mps + if ratio < kernel_floor: + return KernelVerdict( + key=main.key, + main=main, + pr=pr, + ratio=ratio, + status="fail", + reason=f"PR/main = {ratio:.3f}x < kernel floor {kernel_floor:.3f}x", + ) + if ratio < warn_floor: + return KernelVerdict( + key=main.key, + main=main, + pr=pr, + ratio=ratio, + status="warn", + reason=f"PR/main = {ratio:.3f}x < warn floor {warn_floor:.3f}x", + ) + return KernelVerdict( + key=main.key, + main=main, + pr=pr, + ratio=ratio, + status="ok", + reason="", + ) + + +def _geomean(values: Iterable[float]) -> float: + vals = [v for v in values if v > 0] + if not vals: + return 1.0 + return math.exp(sum(math.log(v) for v in vals) / len(vals)) + + +# --------------------------------------------------------------------------- +# Markdown rendering +# --------------------------------------------------------------------------- + + +def _render_hardware(main_system: dict | None, pr_system: dict | None) -> str: + """Render the runner-hardware details for both bench runs. + + Both rustVX builds are benchmarked on the same Phase-3 runner VM, + so the two `system` blocks should match.
