Phase ML1: Pool v1 memset 89.73% overhead 軽量化 (+15.34% improvement)

Browse Source 
## Summary
- ChatGPT により bench_profile.h の setenv segfault を修正（RTLD_NEXT 経由に切り替え）
- core/box/pool_zero_mode_box.h 新設：ENV キャッシュ経由で ZERO_MODE を統一管理
- core/hakmem_pool.c で zero mode に応じた memset 制御（FULL/header/off）
- A/B テスト結果：ZERO_MODE=header で +15.34% improvement（1M iterations, C6-heavy）

## Files Modified
- core/box/pool_api.inc.h: pool_zero_mode_box.h include
- core/bench_profile.h: glibc setenv → malloc+putenv（segfault 回避）
- core/hakmem_pool.c: zero mode 参照・制御ロジック
- core/box/pool_zero_mode_box.h (新設): enum/getter
- CURRENT_TASK.md: Phase ML1 結果記載

## Test Results
| Iterations | ZERO_MODE=full | ZERO_MODE=header | Improvement |
|-----------|----------------|-----------------|------------|
| 10K       | 3.06 M ops/s   | 3.17 M ops/s    | +3.65%     |
| 1M        | 23.71 M ops/s  | 27.34 M ops/s   | **+15.34%** |

運用の心得
- 下層（Remote/Ownership）に疑義がある間は、上層（Publish/Adopt）を “無理に” 積み増さない。
- 変更は常に A/B ガード付きで導入し、SIGUSR2/リングとワンショットログで芯を掴んでから上に進む。

## 健康診断ランと注意事項（Superslab / madvise / Pool 用）
このリポジトリは Superslab / madvise / Pool v1 flatten など OS 依存の経路を多用します。
「いつの間にか壊れていた」を防ぐために、次の“健康診断ラン”と注意事項を守ってください。
- DSO 領域には触らない（Superslab OS Box のフェンス）
- `core/box/ss_os_acquire_box.h` の `ss_os_madvise_guarded()` は **libc/libm/ld.so など DSO 領域を dladdr で検出したら即スキップ** します。
- DSO に対する madvise 試行は **バグ扱い**。`g_ss_madvise_disabled` / DSO-skip ログを必ず 1 回だけ出し、以降は触らない前提です。
- 開発/CI では（必要なら）`HAKMEM_SS_MADVISE_DSO_FAILFAST=1` を使って、「DSO に一度でも触ろうとしたら即 abort」するチェックランを追加してください。
- madvise / vm.max_map_count 用 健康診断ラン
- 目的: Superslab OS Box が ENOMEM(vm.max_map_count) に達しても安全に退避できているか、DSO 領域を誤って触っていないかを確認する。
- 推奨コマンド（C7_SAFE + mid/smallmid, Superslab/madvise 経路の smoke 用）:
```sh
HAKMEM_BENCH_MIN_SIZE=257 \
HAKMEM_BENCH_MAX_SIZE=768 \
HAKMEM_TINY_HEAP_PROFILE=C7_SAFE \
HAKMEM_TINY_C7_HOT=1 \
HAKMEM_TINY_HOTHEAP_V2=0 \
HAKMEM_SMALL_HEAP_V3_ENABLED=1 \
HAKMEM_SMALL_HEAP_V3_CLASSES=0x80 \
HAKMEM_POOL_V2_ENABLED=0 \
HAKMEM_POOL_V1_FLATTEN_ENABLED=0 \
HAKMEM_SS_OS_STATS=1 \
./bench_mid_large_mt_hakmem 5000 256 1
```
- チェックポイント:
- 終了時に `[SS_OS_STATS] ... madvise_enomem=0 madvise_disabled=0` が理想（環境次第で ENOMEM は許容、ただし disabled=1 になっていれば以降の madvise は止まっている）。
- DSO-skip や DSO Fail-Fast ログが出ていないこと（出た場合は ptr 分類/経路を優先的にトリアージ）。
- Pool v1 flatten のプロファイル注意
- LEGACY プロファイル専用の最適化です。`HAKMEM_TINY_HEAP_PROFILE=C7_SAFE` / `C7_ULTRA_BENCH` のときは **コード側で強制OFF** されます。
- flatten を触るときの健康診断ラン（LEGACY想定）:
```sh
HAKMEM_BENCH_MIN_SIZE=257 \
HAKMEM_BENCH_MAX_SIZE=768 \
HAKMEM_TINY_HEAP_PROFILE=LEGACY \
HAKMEM_POOL_V2_ENABLED=0 \
HAKMEM_POOL_V1_FLATTEN_ENABLED=1 \
HAKMEM_POOL_V1_FLATTEN_STATS=1 \
./bench_mid_large_mt_hakmem 1 1000000 400 1
```
- チェックポイント:
- `[POOL_V1_FLAT] alloc_tls_hit` / `free_tls_hit` が増えていること（flatten 経路が効いている）。
- `free_fb_*`（page_null / not_mine / other）は**少数**に収まっていること。増えてきたら owner 判定/lookup 側を優先トリアージする。
- 一般ルール（壊れたらまず健康診断ラン）
- Tiny / Superslab / Pool に手を入れたあと、まず上記の健康診断ランを 1 回だけ回してから長尺ベンチ・本番 A/B に進んでください。
- 健康診断ランが落ちる場合は **新しい最適化を積む前に** Box 境界（ptr 分類 / Superslab OS Box / Pool v1 flatten Box）を優先的に直します。
- ベンチや評価を始めるときは、`docs/analysis/ENV_PROFILE_PRESETS.md` のプリセット（MIXED_TINYV3_C7_SAFE / C6_HEAVY_LEGACY_POOLV1 / DEBUG_TINY_FRONT_PERF）から必ずスタートし、追加した ENV はメモを残してください。単発の ENV を散らすと再現が難しくなります。

## HAKMEM 状況メモ (2025-12-05 更新 / C7 Warm/TLS Bind 反映)
### Phase FP1: Mixed 16–1024B madvise A/B（C7-only v3, front v3+LUT+fast classify ON, ws=400, iters=1M, Release）
- Baseline (MIXED_TINYV3_C7_SAFE, SS_OS_STATS=1): **32.76M ops/s**。`[SS_OS_STATS] madvise=4 madvise_enomem=1 madvise_disabled=1`（warmup で ENOMEM→madvise 停止）。perf: task-clock 50.88ms / minor-faults 6,742 / user 35.3ms / sys 16.2ms。
- Low-madvise（+`HAKMEM_FREE_POLICY=keep HAKMEM_DISABLE_BATCH=1 HAKMEM_SS_MADVISE_STRICT=0`, SS_OS_STATS=1）: **32.69M ops/s**。`madvise=3 enomem=0 disabled=0`。perf: task-clock 54.96ms / minor-faults 6,724 / user 35.1ms / sys 20.8ms。
- Batch+THP 寄り（+`HAKMEM_FREE_POLICY=batch HAKMEM_DISABLE_BATCH=0 HAKMEM_THP=auto`, SS_OS_STATS=1）: **33.24M ops/s**。`madvise=3 enomem=0 disabled=0`。perf: task-clock 49.57ms / minor-faults 6,731 / user 35.4ms / sys 15.1ms。
- 所感: pf/OPS とも大差なし。低 madvise での改善は見られず、Batch+THP 側がわずかに良好（+1〜2%）。vm.max_map_count が厳しい環境で failfast を避けたい場合のみ keep/STRICT=0 に切替える運用が現実的。
### Hotfix: madvise(ENOMEM) を握りつぶし、以降の madvise を停止（Superslab OS Box）
- 変更: `ss_os_madvise_guarded()` を追加し、madvise が ENOMEM を返したら `g_ss_madvise_disabled=1` にして以降の madvise をスキップ。EINVAL だけは従来どおり STRICT=1 で Fail-Fast（ENV `HAKMEM_SS_MADVISE_STRICT` で緩和可）。
- stats: `[SS_OS_STATS]` に `madvise_enomem/madvise_other/madvise_disabled` を追加。HAKMEM_SS_OS_STATS=1 で確認可能。
- ねらい: vm.max_map_count 到達時の大量 ENOMEM で VMA がさらに分割されるのを防ぎ、アロケータ自体は走り続ける。
### PhaseS1: SmallObject v3 C6 トライ前のベースライン（C7-only）
- 条件: Release, `./bench_random_mixed_hakmem 1000000 400 1`、ENV `HAKMEM_BENCH_MIN_SIZE=16 HAKMEM_BENCH_MAX_SIZE=1024 HAKMEM_TINY_HEAP_PROFILE=C7_SAFE HAKMEM_TINY_C7_HOT=1 HAKMEM_TINY_HOTHEAP_V2=0 HAKMEM_SMALL_HEAP_V3_ENABLED=1 HAKMEM_SMALL_HEAP_V3_CLASSES=0x80 HAKMEM_POOL_V2_ENABLED=0`（C7 v3 のみ）。
- 結果: Throughput ≈ **46.31M ops/s**（segv/assert なし、SS/Rel ログのみ）。Phase S1 で C6 v3 を追加する際の比較用ベースとする。
- C6-only v3（research / bench 専用）: `HAKMEM_BENCH_MIN_SIZE=257 MAX_SIZE=768 TINY_HEAP_PROFILE=C7_SAFE TINY_C7_HOT=1 TINY_C6_HOT=1 TINY_HOTHEAP_V2=0 SMALL_HEAP_V3_ENABLED=1 SMALL_HEAP_V3_CLASSES=0x40 POOL_V2_ENABLED=0` → Throughput ≈ **36.77M ops/s**（segv/assert なし）。C6 stats `route_hits=266,930 alloc_refill=5 fb_v1=0 page_of_fail=0`（C7 は v1 ルート）。
- Mixed 16–1024B C6+C7 v3: `HAKMEM_SMALL_HEAP_V3_CLASSES=0xC0 SMALL_HEAP_V3_STATS=1 TINY_C6_HOT=1` で `./bench_random_mixed_hakmem 1000000 400 1` → Throughput ≈ **44.45M ops/s**、`cls6 route_hits=137,307 alloc_refill=1 fb_v1=0 page_of_fail=0` / `cls7 route_hits=283,170 alloc_refill=2,446 fb_v1=0 page_of_fail=0`。C7 slow/refill は従来レンジ。
- 追加 A/B（C6-heavy v1 vs v3）: 同条件 `MIN=257 MAX=768 ws=400 iters=1M` で `CLASSES=0x80`（C6 v1）→ **47.71M ops/s**（v3 stats は cls7 のみ）、`CLASSES=0x40`（C6 v3）→ **36.77M ops/s**。約 -23% で v3 が劣後。
- Mixed 16–1024B 追加 A/B: `CLASSES=0x80`（C7-only）→ **47.45M ops/s**、`CLASSES=0xC0`（C6+C7 v3）→ **44.45M ops/s**（約 -6%）。cls6 stats は route_hits=137,307 alloc_refill=1 fb_v1=0 page_of_fail=0。
- 方針: デフォルトは C7-only（mask 0x80）のまま。C6 v3 は `HAKMEM_SMALL_HEAP_V3_CLASSES` bit6 で明示 opt-in（研究箱）。ベンチ時は `HAKMEM_TINY_C6_HOT=1` を併用して tiny front を確実に通す。C6 v3 は現状 C6-heavy/Mixed とも性能マイナスのため、研究箱据え置き。
- 確定: 標準プロファイルは `HAKMEM_SMALL_HEAP_V3_CLASSES=0x80`（C7-only v3 固定）。bit6（C6）は研究専用で本線に乗せない。
- C6-heavy / C6 を v1 固定で走らせる推奨プリセット:
```
HAKMEM_BENCH_MIN_SIZE=257
HAKMEM_BENCH_MAX_SIZE=768
HAKMEM_TINY_HEAP_PROFILE=C7_SAFE
HAKMEM_TINY_C6_HOT=1
HAKMEM_SMALL_HEAP_V3_ENABLED=1
HAKMEM_SMALL_HEAP_V3_CLASSES=0x80 # C7-only v3
```
### Mixed 16–1024B 新基準（C7-only v3 / front v3 ON, 2025-12-05）
- ENV: `HAKMEM_BENCH_MIN_SIZE=16 MAX_SIZE=1024 TINY_HEAP_PROFILE=C7_SAFE TINY_C7_HOT=1 TINY_HOTHEAP_V2=0 SMALL_HEAP_V3_ENABLED=1 SMALL_HEAP_V3_CLASSES=0x80 POOL_V2_ENABLED=0`（front v3/LUT はデフォルト ON、v3 stats ON）。
- HAKMEM: **44.45M ops/s**、`cls7 alloc_refill=2446 fb_v1=0 page_of_fail=0`（segv/assert なし）。
- mimalloc: **117.20M ops/s**。system: **90.95M ops/s**。→ HAKMEM は mimalloc の約 **38%**、system の約 **49%**。
### C6-heavy 最新ベースライン（C6 v1 固定 / flatten OFF, 2025-12-05）
- ENV: `HAKMEM_BENCH_MIN_SIZE=257 MAX_SIZE=768 TINY_HEAP_PROFILE=C7_SAFE TINY_C6_HOT=1 SMALL_HEAP_V3_ENABLED=1 SMALL_HEAP_V3_CLASSES=0x80 POOL_V2_ENABLED=0 POOL_V1_FLATTEN_ENABLED=0`。
- HAKMEM: **29.01M ops/s**（segv/assert なし）。Phase80/82 以降の比較用新基準。
### Phase80: mid/smallmid Pool v1 flatten（C6-heavy）
- 目的: mid/smallmid の pool v1 ホットパスを薄くし、C6-heavy ベンチで +5〜10% 程度の底上げを狙う。
- 実装: `core/hakmem_pool.c` に v1 専用のフラット化経路（`hak_pool_try_alloc_v1_flat` / `hak_pool_free_v1_flat`）を追加し、TLS ring/lo hit 時は即 return・その他は従来の `_v1_impl` へフォールバックする Box に分離。ENV `HAKMEM_POOL_V1_FLATTEN_ENABLED`（デフォルト0）と `HAKMEM_POOL_V1_FLATTEN_STATS` でオンオフと統計を制御。

v2 内部のリスト (`current_page` / `partial_pages` / `full_pages`) から unlink したら Hot 側の state を全て破棄する。
3. `TinyColdIface` を **「refill/retire だけの境界」**として明確化し、Hot Box から Cold Box への侵入（meta/used/freelist の直接操作）をこれ以上増やさない。
4. C7-only で v2 ON/OFF を A/B しつつ、`cold_refill_fail` が 0 に張り付いていること、`alloc_fast` ≈ v1 の `fast` 件数に近づいていることを確認する（性能よりもまず安定性・境界の分離を優先）。
### Phase ML1: Pool v1 Zero コスト削減（memset 89.73% 軽量化）
**背景**: C6-heavy（mid/smallmid, Pool v1/flatten 系）ベンチで `__memset_avx2_unaligned_erms` が self **89.73%** を占有（perf 実測）。
**実装**: ChatGPT により修正完了
- `core/box/pool_zero_mode_box.h` 新設（ENV キャッシュ経由で ZERO_MODE を統一管理）
- `core/bench_profile.h`: glibc setenv 呼び出しをセグフォから守るため、RTLD_NEXT 経由の malloc+putenv に切り替え
- `core/hakmem_pool.c`: zero mode に応じた memset 制御（FULL/header/off）
**A/B テスト結果（C6-heavy, PROFILE=C6_HEAVY_LEGACY_POOLV1, flatten OFF）**:
| Iterations | ZERO_MODE=full | ZERO_MODE=header | 改善 |
|-----------|----------------|-----------------|------|
| 10K | 3.06 M ops/s | 3.17 M ops/s | **+3.65%** |
| **1M** | **23.71 M ops/s** | **27.34 M ops/s** | **+15.34%** 🚀 |
**所感**: イテレーション数が増えると改善率も大きくなる（memset overhead の割合が増加）。header mode で期待値 +3-5% を大幅に超える +15% の改善を実現。デフォルトは `ZERO_MODE=full`（安全側）のまま、bench/micro-opt 時のみ `export HAKMEM_POOL_ZERO_MODE=header` で opt-in。
**環境変数**:
```bash
# ベースライン（フル zero）
export HAKMEM_PROFILE=C6_HEAVY_LEGACY_POOLV1
./bench_mid_large_mt_hakmem 1 1000000 400 1
# → 23.71 M ops/s
# 軽量 zero（header + guard のみ）
export HAKMEM_PROFILE=C6_HEAVY_LEGACY_POOLV1
export HAKMEM_POOL_ZERO_MODE=header
./bench_mid_large_mt_hakmem 1 1000000 400 1
# → 27.34 M ops/s (+15.34%)
```
**次のステップ**: Phase 82 の full flatten が C7_SAFE で crash する理由を調査し、+13% の改善を実現することを検討。

# PHASE ML1: ChatGPT 依頼用ガイド（Pool v1 memset 89.73% 課題）
## 1. 背景情報
- mid/smallmid (C6-heavy, Pool v1/flatten 系) のベンチで `__memset_avx2_unaligned_erms` が self 89.73% を占有（perf 実測）。
- 目的: Pool v1 の zero コストを減らす（デフォルト安全は維持しつつ、ベンチ専用の opt-in を用意）。
- 現状: zero mode を pool_api.inc.h に直接足したところ、ベンチ起動直後にセグフォが発生。
## 2. 問題の詳細
- セグフォの推測要因
- pool_api.inc.h が複数翻訳単位から include され、`static` キャッシュ変数が TU ごとにばらける。
- ENV 読み取りをヘッダ内で直接行ったため、初期化順や再定義が崩れている可能性。
- ZERO_MODE=header 実装が TLS/flatten 経路と食い違っているかもしれない。
- 現在のコード（問題箇所のイメージ）
- `HAKMEM_POOL_ZERO_MODE` をヘッダ内で `static int g=-1; getenv(...);` する小さな関数を追加しただけで segfault。
## 3. 修正案（2択）
- 選択肢 A: Environment Cache を使う（推奨）
- `core/hakmem_env_cache.h` など既存の ENV キャッシュ箱に「pool_zero_mode」を追加し、ヘッダ側は薄い getter だけにする。
- 1 箇所で getenv/パース → 全翻訳単位で一貫させる（箱理論: 変換点を 1 箇所に）。
- 選択肢 B: 制約を緩和（暫定）
- ヘッダで ENV を読まない。zero/partial memset を呼ぶかどうかを、C 側の単一関数で判定して呼び出すだけに戻す。
- まずセグフォを解消し、memset の最適化は後続フェーズに送る。
## 4. 詳細な調査手順
- memset 呼び出し元の再確認
```bash
rg \"memset\" core/hakmem_pool.c core/box/pool_api.inc.h
```
- perf の再取得（C6-heavy LEGACY/flatten なし）
```bash
export HAKMEM_PROFILE=C6_HEAVY_LEGACY_POOLV1
perf record -F 5000 --call-graph dwarf -e cycles:u -o perf.data.ml1 \
./bench_mid_large_mt_hakmem 1 1000000 400 1
perf report -i perf.data.ml1 --stdio | rg memset
perf annotate -i perf.data.ml1 __memset_avx2_unaligned_erms | head -40
```
- 呼び出し階層を掘る（TLS alloc か slow path かを確認）
```bash
perf script -i perf.data.ml1 --call-trace | rg -C2 'memset'
```
## 5. 実装の方向性の再検討
- TLS alloc path で memset が本当に呼ばれているかを必ず確認（`hak_pool_try_alloc_v1_flat` 周辺）。
- memset が page 初期化のみなら、ZERO_MODE は TLS ring には効かない可能性 → 方針を「page 初期化の頻度を減らす」に切替も検討。
- ZERO_MODE を入れる場合も:
- ENV キャッシュを 1 箇所に集約。
- デフォルトは FULL zero、header/off は bench opt-in。
- Fail-Fast: 異常 ENV はログして既定値にフォールバック。
## 6. テストコマンド（A/B）
```bash
# ベースライン（FULL zero）
export HAKMEM_PROFILE=C6_HEAVY_LEGACY_POOLV1
timeout 120 ./bench_mid_large_mt_hakmem 1 1000000 400 1
# header mode（memset を軽量化する実装を入れたら）
export HAKMEM_PROFILE=C6_HEAVY_LEGACY_POOLV1
export HAKMEM_POOL_ZERO_MODE=header
timeout 120 ./bench_mid_large_mt_hakmem 1 1000000 400 1
```
- 比較: ops/s, SS/POOL stats（あれば memset 呼び出し数 proxy）、セグフォ/アサートがないこと。
- header mode で +3〜5% 程度伸びれば成功。負になれば撤回 or slow-path のみに適用。

- 新規比較表: `PERF_COMPARISON_ALLOCATORS.md` に HAKMEM (full/larson_guard) / mimalloc / system の ops/s と RSS を掲載。C7-only/129–1024/full いずれも HAKMEM は ~50M ops/s / ~29MB RSS、system/mimalloc は 75–126M ops/s / 1.6–1.9MB RSS で優位。
- Random Mixed 129–1024B, ws=256, iters=1M, `HAKMEM_WARM_TLS_BIND_C7=2`:

# ENV Profile Presets (HAKMEM)
よく使う構成を 3 つのプリセットにまとめました。まずここからコピペし、必要な ENV だけを追加してください。v2 系や LEGACY 専用オプションは明示 opt-in で扱います。
ベンチバイナリでは `HAKMEM_PROFILE=<名前>` をセットすると、ここで定義した ENV を自動で注入します（既に設定済みの ENV は上書きしません）。
---
## Profile 1: MIXED_TINYV3_C7_SAFE（標準 Mixed 16–1024B）
### 目的
- Mixed 16–1024B の標準ベンチ用。
- C7-only SmallObject v3 + Tiny front v3 + LUT + fast classify ON。
- Tiny/Pool v2 はすべて OFF。
### ENV 最小セット（Release）
```sh
HAKMEM_BENCH_MIN_SIZE=16
HAKMEM_BENCH_MAX_SIZE=1024
HAKMEM_TINY_HEAP_PROFILE=C7_SAFE
HAKMEM_TINY_C7_HOT=1
HAKMEM_TINY_HOTHEAP_V2=0
HAKMEM_SMALL_HEAP_V3_ENABLED=1
HAKMEM_SMALL_HEAP_V3_CLASSES=0x80
HAKMEM_POOL_V2_ENABLED=0
HAKMEM_TINY_FRONT_V3_ENABLED=1
HAKMEM_TINY_FRONT_V3_LUT_ENABLED=1
HAKMEM_TINY_PTR_FAST_CLASSIFY_ENABLED=1
HAKMEM_FREE_POLICY=batch
HAKMEM_THP=auto
```
### 任意オプション
- stats を見たいとき:
```sh
HAKMEM_TINY_HEAP_STATS=1
HAKMEM_TINY_HEAP_STATS_DUMP=1
HAKMEM_SMALL_HEAP_V3_STATS=1
```
- v2 系は触らない（C7_SAFE では Pool v2 / Tiny v2 は常時 OFF）。
- vm.max_map_count が厳しい環境で Fail-Fast を避けたいときの応急処置（性能はほぼ同等〜微減）:
```sh
HAKMEM_FREE_POLICY=keep
HAKMEM_DISABLE_BATCH=1
HAKMEM_SS_MADVISE_STRICT=0
```
---
## Profile 2: C6_HEAVY_LEGACY_POOLV1（mid/smallmid C6-heavy ベンチ）
### 目的
- C6-heavy mid/smallmid のベンチ用。
- C6 は v1 固定（C6 v3 OFF）、Pool v2 OFF。Pool v1 flatten は bench 用に opt-in。
### ENV（v1 基準線）
```sh
HAKMEM_BENCH_MIN_SIZE=257
HAKMEM_BENCH_MAX_SIZE=768
HAKMEM_TINY_HEAP_PROFILE=C7_SAFE
HAKMEM_TINY_C6_HOT=1
HAKMEM_TINY_HOTHEAP_V2=0
HAKMEM_SMALL_HEAP_V3_ENABLED=1
HAKMEM_SMALL_HEAP_V3_CLASSES=0x80 # C7-only v3, C6 v3 は OFF
HAKMEM_POOL_V2_ENABLED=0
HAKMEM_POOL_V1_FLATTEN_ENABLED=0 # flatten は初回 OFF
```
### Pool v1 flatten A/B 用（LEGACY 専用）
```sh
# LEGACY + flatten ON (研究/bench専用)
HAKMEM_TINY_HEAP_PROFILE=LEGACY
HAKMEM_POOL_V2_ENABLED=0
HAKMEM_POOL_V1_FLATTEN_ENABLED=1
HAKMEM_POOL_V1_FLATTEN_STATS=1
```
- flatten は LEGACY 専用。C7_SAFE / C7_ULTRA_BENCH ではコード側で強制 OFF になる前提。
---
## Profile 3: DEBUG_TINY_FRONT_PERF（perf 用 DEBUG プロファイル）
### 目的
- Tiny front v3（C7 v3 含む）の perf record 用。
- -O0 / -g / LTO OFF でシンボル付き計測。
### ビルド例
```sh
make clean
CFLAGS='-O0 -g' USE_LTO=0 OPT_LEVEL=0 NATIVE=0 \
make bench_random_mixed_hakmem -j4
```
### ENV
```sh
HAKMEM_BENCH_MIN_SIZE=16
HAKMEM_BENCH_MAX_SIZE=1024
HAKMEM_TINY_HEAP_PROFILE=C7_SAFE
HAKMEM_TINY_C7_HOT=1
HAKMEM_TINY_HOTHEAP_V2=0
HAKMEM_SMALL_HEAP_V3_ENABLED=1
HAKMEM_SMALL_HEAP_V3_CLASSES=0x80
HAKMEM_POOL_V2_ENABLED=0
HAKMEM_TINY_FRONT_V3_ENABLED=1
HAKMEM_TINY_FRONT_V3_LUT_ENABLED=1
HAKMEM_TINY_PTR_FAST_CLASSIFY_ENABLED=1
```
### perf 例
```sh
perf record -F 5000 --call-graph dwarf -e cycles:u \
-o perf.data.tiny_front_tf3 \
./bench_random_mixed_hakmem 1000000 400 1
```
- perf 計測時はログを極力 OFF、ENV は MIXED_TINYV3_C7_SAFE をベースにする。
---
### 共通注意
- プリセットから外れて単発の ENV を積み足すと再現が難しくなるので、まずは上記いずれかからスタートし、変更点を必ずメモしてください。
- v2 系（Pool v2 / Tiny v2）はベンチごとに opt-in。不要なら常に 0。

@ -28,6 +28,23 @@ SmallObject HotBox v3 Design (Tiny + mid/smallmid 統合案)
- Route: `tiny_route_env_box.h` に `TINY_ROUTE_SMALL_HEAP_V3` を追加。クラスビットが立っているときだけ route snapshot で v3 に振り分け。
- Front: malloc/free で v3 route を試し、失敗時は v2/v1/legacy に落とす直線パス。デフォルトは OFF なので挙動は従来通り。
### Phase S1: C6 v3 研究箱（C7 を壊さずにベンチ限定で解禁）
- Gate: `HAKMEM_SMALL_HEAP_V3_ENABLED`/`CLASSES` の bit7=C7（デフォルト ON=0x80）、bit6=C6（research-only、デフォルト OFF）。C6 を叩くときは `HAKMEM_TINY_C6_HOT=1` を併用して tiny front を確実に通す。
- Cold IF: `smallobject_cold_iface_v1.h` を C6 にも適用し、`tiny_heap_prepare_page`/`page_becomes_empty` を C7 と同じ形で使う。v3 stats に `page_of_fail` を追加し、free 側の page_of ミスを計測。
- Bench (Release, Tiny/Pool v2 OFF, ws=400, iters=1M):

- 運用方針: 標準プロファイルは `HAKMEM_SMALL_HEAP_V3_CLASSES=0x80`（C7-only v3）に確定。C6 v3 は bench/研究のみ明示 opt-in とし、C6-heavy/Mixed の本線には乗せない。性能が盛り返すまで研究箱据え置き。

- route/guard 判定（unified_cache_enabled / tiny_guard_is_enabled / classify_ptr）が合わせて ~6% 程度。
- 次は「size→class→route 前段＋header」をフラット化するターゲットが有力。
## TF3 事前計測（DEBUGシンボル, front v3+LUT ON, C7-only v3）
環境: `HAKMEM_BENCH_MIN_SIZE=16 HAKMEM_BENCH_MAX_SIZE=1024 HAKMEM_TINY_HEAP_PROFILE=C7_SAFE HAKMEM_TINY_C7_HOT=1 HAKMEM_TINY_HOTHEAP_V2=0 HAKMEM_POOL_V2_ENABLED=0 HAKMEM_SMALL_HEAP_V3_ENABLED=1 HAKMEM_SMALL_HEAP_V3_CLASSES=0x80 HAKMEM_TINY_FRONT_V3_ENABLED=1 HAKMEM_TINY_FRONT_V3_LUT_ENABLED=1`
ビルド: `BUILD_FLAVOR=debug OPT_LEVEL=0 USE_LTO=0 EXTRA_CFLAGS=-g`
ベンチ: `perf record -F5000 --call-graph dwarf -e cycles:u -o perf.data.tiny_front_tf3 ./bench_random_mixed_hakmem 1000000 400 1`
Throughput: **12.39M ops/s**（DEBUG/-O0 相当）
- `ss_map_lookup`: **7.3% self**（free 側での ptr→SuperSlab 判定が主、C7 v3 でも多い）
- `hak_super_lookup`: **4.0% self**（lookup fallback 分）
- `classify_ptr`: **0.64% self**（free の入口 size→class 判定）
- `mid_desc_lookup`: **0.43% self**（mid 経路の記述子検索）
- そのほか: free/malloc/main が約 30% 強、header write 系は今回のデバッグログに埋もれて確認できず。
所感:
- front v3 + LUT ON でも free 側の `ss_map_lookup` / `hak_super_lookup` が ~11% 程度残っており、ここを FAST classify で直叩きする余地が大きい。
- `classify_ptr` は 1% 未満だが、`ss_map_lookup` とセットで落とせれば +5〜10% の目標に寄せられる見込み。
### Front v3 snapshot 導入メモ
- `TinyFrontV3Snapshot` を追加し、`unified_cache_on / tiny_guard_on / header_mode` を 1 回だけキャッシュする経路を front v3 ON 時に通すようにした（デフォルト OFF）。
- Mixed 16–1024B (ws=400, iters=1M, C7 v3 ON, Tiny/Pool v2 OFF) で挙動変化なし（slow=1 維持）。ホットスポットは依然 front 前段 (`tiny_region_id_write_header`, `ss_map_lookup`, guard/route 判定) が中心。

- header_v3=1 + SKIP_C7=1: 43.68M ops/s（約 -1.4%）、prepare_calls=2446、fallback/page_of_fail=0
- 所感: C7 v3 のヘッダ簡略だけでは perf 改善は見えず。free 側のヘッダ依存を落とす or header light/off を別箱で検討する必要あり。
## TF3: ptr fast classify 実装後の A/B（C7-only v3, front v3+LUT ON）
- Releaseビルド, ws=400, iters=1M, ENV は TF3 基準 (`C7_SAFE`, C7_HOT=1, v2/pool v2=0, v3 classes=0x80, front v3/LUT ON)。
- Throughput (ops/s):
- PTR_FAST_CLASSIFY=0: **33.91M**
- PTR_FAST_CLASSIFY=1: **36.67M**（約 +8.1%）
- DEBUG perf（同ENV, gate=1, cycles@5k, dwarf）: `ss_map_lookup` self が **7.3% → 0.9%**、`hak_super_lookup` はトップから消失。代わりに TLS 内のページ判定 (`smallobject_hotbox_v3_can_own_c7` / `so_page_of`) が合計 ~5.5% へ移動。`classify_ptr` は 2–3% まで微増（外れ時のフォールバック分）。
- 所感: C7 v3 free の Superslab lookup 往復をほぼ除去でき、目標の +5〜10% に収まる結果。fast path 判定の TLS 走査が新たなホットスポットだが、現状コストは lookup より低く許容範囲。

- 所感: 短尺の header スキップだけでは改善なし。free 側の header 依存を外す or header_light 再設計を別フェーズで検討。
## Phase TF3: ptr fast classify（設計メモ / 実装TODO）
- ENV ゲート（デフォルト 0、A/B でのみ ON）
- `HAKMEM_TINY_PTR_FAST_CLASSIFY_ENABLED`
- 目的: C7 v3 free の入口で「明らかに Tiny/C7 のページ」だけを fast path に送り、`classify_ptr → ss_map_lookup → mid_desc_lookup` の往復を避ける。外れたら必ず従来の classify_ptr 経路へフォールバックする。
- デザイン（free 側, malloc_tiny_fast.h 想定）:
1. gate ＋ C7 v3 が有効かを Snapshot で確認（C6/Pool/off のときは何もしない）。
2. ptr から TLS context / so_page_of / page metadata だけで「self-thread の C7 v3 ページ」かを判定。
3. 判定 OK → `ss_map_lookup` を通さず C7 v3 の free 直行。
4. 判定 NG → 現行の classify_ptr/ss_map_lookup にそのまま落とす（Box 境界は不変）。
- 実装担当向け TODO:
- ENV gate 追加（デフォルト 0）。
- free 入口に C7 v3 専用 fast classify を追加（必ずフォールバックあり）。
- A/B: Mixed 16–1024B, C7 v3 ON, front v3/LUT ON, Tiny/Pool v2 OFF
- baseline: PTR_FAST_CLASSIFY=0
- trial: PTR_FAST_CLASSIFY=1
- 期待: segv/assert なし、`ss_map_lookup / classify_ptr` self% 減、ops/s が +数%〜+10% 方向。
### 実装後メモ（2025/TF3）
- 実装: `tiny_ptr_fast_classify_enabled` ゲート追加、free 入口で C7 v3 の TLS ページ判定（`smallobject_hotbox_v3_can_own_c7`）が当たれば `so_free` へ直行。外れは従来 route/classify へフォールバック。
- Mixed 16–1024B (C7-only v3, front v3+LUT ON, v2/pool v2 OFF, ws=400, iters=1M, Release):
- OFF: 33.9M ops/s → ON: 36.7M ops/s（約 +8.1%）。
- DEBUG perf (cycles@5k, dwarf, gate=1): `ss_map_lookup` self が 7.3% → 0.9%、`hak_super_lookup` はトップ外へ。TLS 走査 (`smallobject_hotbox_v3_can_own_c7`) が ~5.5% に現れるが lookup 往復より低コスト。
- ロールアウト案: Mixed 基準でプラスが安定しているため、front v3/LUT ON 前提では fast classify もデフォルトON候補。ENV=0 で即オフに戻せる構造は維持。
