Phase v11a-3: MID v3.5 Activation (Build Complete)
Integrated MID v3.5 into active code path, making it available for C5/C6/C7 routing. Key Changes: - Policy Box: Added SMALL_ROUTE_MID_V35 with ENV gates (HAKMEM_MID_V35_ENABLED, HAKMEM_MID_V35_CLASSES) - HotBox: Implemented small_mid_v35_alloc/free with TLS-cached page allocation - Front Gate: Wired MID_V35 routing into malloc_tiny_fast.h (priority: ULTRA > MID_V35 > V7) - Build: Added core/smallobject_mid_v35.o to all object lists Architecture: - Slot sizes: C5=384B, C6=512B, C7=1024B - Page size: 64KB (170/128/64 slots) - Integration: ColdIface v2 (refill/retire), Stats v2 (observation), Learner v2 (dormant) Status: Build successful, ready for A/B benchmarking Next: Performance validation (C6-heavy, C5+C6-only, Mixed benchmarks) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

// - Uses Segment v2 + ColdIface v2 + Stats v2 + Learner v2

# Phase v11a-3: MID v3.5 Implementation Summary
|
||||
|
||||
**Date:** 2025-12-12
|
||||
**Status:** Build Complete - Ready for A/B Benchmarking
|
||||
**Author:** Claude Opus 4.5
|
||||
|
||||
## Overview
|
||||
|
||||
Phase v11a-3 successfully integrated MID v3.5 into the active code path, making it available for routing C5/C6/C7 allocations. This phase activates the Segment/ColdIface/Stats/Learner v2 infrastructure implemented in Phase v11a-2.
|
||||
|
||||
## Implementation Tasks Completed
|
||||
|
||||
### Task 1: Policy Box Updates (L3)
|
||||
|
||||
**Files Modified:**
|
||||
- `/mnt/workdisk/public_share/hakmem/core/box/smallobject_policy_v7_box.h`
|
||||
- `/mnt/workdisk/public_share/hakmem/core/smallobject_policy_v7.c`
|
||||
|
||||
**Changes:**
|
||||
1. Added `SMALL_ROUTE_MID_V35` to `SmallRouteKind` enum
|
||||
2. Implemented ENV gate functions:
|
||||
- `mid_v35_enabled()` - checks `HAKMEM_MID_V35_ENABLED`
|
||||
- `mid_v35_class_mask()` - reads `HAKMEM_MID_V35_CLASSES` (default: 0x60 for C5+C6)
|
||||
3. Updated policy init with priority: ULTRA > MID_V35 > V7 > MID_V3 > LEGACY
|
||||
4. Added MID_V35 case to `small_route_kind_name()`
|
||||
|
||||
### Task 2: MID v3.5 HotBox Implementation (L1)
|
||||
|
||||
**Files Created:**
|
||||
- `/mnt/workdisk/public_share/hakmem/core/box/smallobject_mid_v35_box.h` - Public API
|
||||
- `/mnt/workdisk/public_share/hakmem/core/smallobject_mid_v35.c` - Implementation
|
||||
|
||||
**Implementation:**
|
||||
- TLS-cached page allocation (per-class fast path)
|
||||
- Slot sizes: C5=384B, C6=512B, C7=1024B
|
||||
- Page size: 64KB (170/128/64 slots for C5/C6/C7)
|
||||
- Alloc: Fast path (TLS cache hit) + Slow path (refill via ColdIface)
|
||||
- Free: Simplified counting (no freelist yet - deferred to v11b)
|
||||
- Header writing: Integrates with tiny_region_id_write_header
|
||||
|
||||
**Key Design Decisions:**
|
||||
- Reused `SmallPageMeta` typedef (matches segment/cold_iface structure)
|
||||
- Simplified free path (cross-page free deferred to v11b RegionIdBox integration)
|
||||
- Header integration for compatibility with existing Tiny infrastructure
|
||||
|
||||
### Task 3: Front Gate Integration (L0/L1 Boundary)
|
||||
|
||||
**Files Modified:**
|
||||
- `/mnt/workdisk/public_share/hakmem/core/front/malloc_tiny_fast.h`
|
||||
|
||||
**Changes:**
|
||||
1. Added MID v3.5 box header include
|
||||
2. Alloc path: Check policy for MID_V35, call `small_mid_v35_alloc()` before V7
|
||||
3. Free path: Check policy for MID_V35, call `small_mid_v35_free()` after ULTRA checks
|
||||
|
||||
**Priority Order (Alloc/Free):**
|
||||
1. ULTRA (C4-C7)
|
||||
2. MID v3.5 (Policy-driven)
|
||||
3. V7 (Policy-driven)
|
||||
4. Legacy routes
|
||||
|
||||
### Task 4: Build System Updates
|
||||
|
||||
**Files Modified:**
|
||||
- `/mnt/workdisk/public_share/hakmem/Makefile`
|
||||
|
||||
**Changes:**
|
||||
- Added `core/smallobject_mid_v35.o` to `OBJS_BASE`

|
||||
## ENV Configuration
|
||||
|
||||
### MID v3.5 Activation
|
||||
|
||||
```bash
|
||||
# Enable MID v3.5
|
||||
export HAKMEM_MID_V35_ENABLED=1
|
||||
|
||||
# Configure classes (default: 0x60 = C5+C6)
|
||||
export HAKMEM_MID_V35_CLASSES=0x60 # C5 + C6
|
||||
# export HAKMEM_MID_V35_CLASSES=0x20 # C5 only
|
||||
# export HAKMEM_MID_V35_CLASSES=0x40 # C6 only
|
||||
```
|
||||
|
||||
### Policy Debug Output
|
||||
|
||||
Policy initialization prints route assignments on first call:
|
||||
```
|
||||
[POLICY_V7_INIT] Route assignments:
|
||||
C0: LEGACY
|
||||
C1: LEGACY
|
||||
C2: LEGACY
|
||||
C3: LEGACY
|
||||
C4: ULTRA
|
||||
C5: MID_V35
|
||||
C6: MID_V35
|
||||
C7: ULTRA
|
||||
```
|
||||
|
||||
## Next Steps (Task 5: A/B Benchmarks)
|
||||
|
||||
### Benchmark 1: C6-Heavy (MID Specialization Check)
|
||||
|
||||
```bash
|
||||
# Baseline: MID v3.5 OFF
|
||||
HAKMEM_PROFILE=C6_HEAVY_LEGACY_POOLV1 \
|
||||
HAKMEM_MID_V35_ENABLED=0 \
|
||||
./bench_mid_large_mt_hakmem 1 1000000 400 1
|
||||
|
||||
# Test: MID v3.5 ON (C6 only)
|
||||
HAKMEM_PROFILE=C6_HEAVY_LEGACY_POOLV1 \
|
||||
HAKMEM_MID_V35_ENABLED=1 \
|
||||
HAKMEM_MID_V35_CLASSES=0x40 \
|
||||
./bench_mid_large_mt_hakmem 1 1000000 400 1
|
||||
```
|
||||
|
||||
**Expected:** Performance within ±5% of MID v3
|
||||
|
||||
### Benchmark 2: C5+C6-Only (257-768B Range)
|
||||
|
||||
```bash
|
||||
# Baseline: MID v3.5 OFF
|
||||
HAKMEM_BENCH_MIN_SIZE=257 \
|
||||
HAKMEM_BENCH_MAX_SIZE=768 \
|
||||
HAKMEM_MID_V35_ENABLED=0 \
|
||||
./bench_random_mixed_hakmem 1000000 400 1
|
||||
|
||||
# Test: MID v3.5 ON (C5+C6)
|
||||
HAKMEM_BENCH_MIN_SIZE=257 \
|
||||
HAKMEM_BENCH_MAX_SIZE=768 \
|
||||
HAKMEM_MID_V35_ENABLED=1 \
|
||||
HAKMEM_MID_V35_CLASSES=0x60 \
|
||||
./bench_random_mixed_hakmem 1000000 400 1
|
||||
```
|
||||
|
||||
**Expected:** +2-4% improvement (matching v7 gains)
|
||||
|
||||
### Benchmark 3: Mixed 16-1024B (Reference)
|
||||
|
||||
```bash
|
||||
HAKMEM_PROFILE=MIXED_TINYV3_C7_SAFE \
|
||||
HAKMEM_MID_V35_ENABLED=1 \
|
||||
HAKMEM_MID_V35_CLASSES=0x60 \
|
||||
./bench_random_mixed_hakmem 1000000 400 1
|
||||
```
|
||||
|
||||
**Expected:** Baseline ±3% (no regression)
|
||||
|
||||
## Known Limitations (Deferred to v11b)
|
||||
|
||||
1. **Cross-Page Free:** Current implementation only handles frees to the current TLS page
|
||||
- Need RegionIdBox lookup for cross-page free
|
||||
- Planned for v11b with proper segment ownership check
|
||||
|
||||
2. **Freelist Reuse:** No freelist implementation yet
|
||||
- Slots are marked free via counter only
|
||||
- Full freelist support planned for v11b
|
||||
|
||||
3. **Learner Route Switching:** Learner v2 is in observation mode only
|
||||
- Dynamic route switching deferred to v11b
|
||||
- Current implementation: static routing based on ENV
|
||||
|
||||
## Code Quality
|
||||
|
||||
- **Modularity:** Clean L1/L2/L3 separation maintained
|
||||
- **Box Boundaries:** Proper isolation between HotBox/ColdIface/Stats/Learner
|
||||
- **Header Compatibility:** Integrates with existing Tiny region_id infrastructure
|
||||
- **Build Hygiene:** All targets compile cleanly (only unused parameter warnings)

||||
|
||||
```
|
||||

|
||||
L1 (HotBox) smallobject_mid_v35.c
|
||||
↓ (Refill needed?)
|
||||
L2 (Cold) smallobject_cold_iface_mid_v3.c
|
||||
↓ (Get page from segment)
|
||||
L2 (Segment) smallobject_segment_mid_v3.c
|
||||
↓ (Stats recording)
|
||||
L2 (Stats) smallobject_stats_mid_v3.c
|
||||
↓ (Learner evaluation - observation only)
|
||||
L2 (Learner) smallobject_learner_v2.c
|
||||
↓ (Policy update - dormant)
|
||||
L3 (Policy) smallobject_policy_v7.c
|
||||
```
|
||||
|
||||
### Memory Layout
|
||||
|
||||
- **Segment:** 2 MiB contiguous region
|
||||
- **Pages:** 64KB per page
|
||||
- **Slots:** 384B (C5), 512B (C6), 1024B (C7)
|
||||
- **TLS Cache:** One current page per class per thread
|
||||
|
||||
## Conclusion
|
||||
|
||||
Phase v11a-3 successfully activated MID v3.5 infrastructure. The implementation is ready for A/B benchmarking to validate performance against the original MID v3 and establish a baseline for future optimizations.
|
||||
|
||||
**Status:** ✅ Build Complete
|
||||
**Next:** Task 5 (A/B Benchmarks) - Performance validation
|
||||
**Future:** Task 6 (Documentation) - Results recording
