Strix Halo Optimization Toolkit

Audit, monitor, benchmark, and optimize AMD Strix Halo integrated GPU systems for LLM inference workloads.

Target hardware: AMD Ryzen AI MAX+ 395 / Radeon 8060S (gfx1151) with 64 GB unified memory, on Fedora 43. Tested on HP ZBook Ultra G1a.

Quick Start

make audit                # See current system status and optimization score
make monitor-install      # Install amdgpu_top + btop
make benchmark-setup      # Create toolbox containers + download test model
make benchmark-baseline   # Capture performance before optimization

System Status

make audit produces a single-screen overview:

=== Memory Allocation ===
  [!!] VRAM (dedicated)               32.0 GiB — should be 0.5 GiB in BIOS
  [!!] GTT (dynamic)                  15.5 GiB — should be ~59.0 GiB with kernel params

=== Kernel Boot Parameters ===
  [!!] iommu=pt                       MISSING
  [!!] amdgpu.gttsize                 MISSING — recommended: 60416
  [!!] ttm.pages_limit                MISSING — recommended: 15466496

=== Performance Profile ===
  [!!] Tuned profile                  throughput-performance — recommended: accelerator-performance

=== Optimization Score ===
  2 / 8 checks passing

Each [!!] is an optimization opportunity. Run make optimize to address them.

Optimization Workflow

1. Audit          make audit
      │
2. Monitor        make monitor-install && make monitor
      │
3. Baseline       make benchmark-setup && make benchmark-baseline
      │
4. Optimize       sudo make optimize
      │               ├── tuned profile  (instant, +5-8% pp)
      │               ├── kernel params  (reboot required)
      │               └── BIOS VRAM      (reboot + BIOS access)
      │
5. Verify         make verify
      │
6. Re-benchmark   make benchmark && make benchmark-compare BEFORE=... AFTER=...
