Hardware support

Kraftverk is an AMD-exclusive performance engineering platform. Policy amd-only-v1 is a hard execution gate across CLI, desktop, SDK, agent, and optimizer — not a cosmetic preference.

Independent product disclaimer: Kraftverk is not affiliated with, endorsed by, or impersonating Advanced Micro Devices, Inc. “AMD” here means CPU/GPU vendor identity detected on the host (CPUID / PCI), not a partnership claim.

Supported configuration

Check	Rule
Architecture	`x86` or `x86_64` only (`compile_error!` on other targets)
CPU vendor	AMD (`AuthenticAMD`) via CPUID
GPU	None → allowed; if present, all must be AMD (PCI vendor `0x1002`)
Blocked	Intel CPU; NVIDIA GPU (`0x10DE`); Intel GPU (`0x8086`); mixed AMD+NVIDIA; unknown vendors

Pass examples: AMD CPU + no GPU; AMD CPU + AMD GPU(s).
Fail examples: Intel CPU; AMD CPU + NVIDIA; AMD+NVIDIA multi-GPU; ARM/aarch64 builds.

Policy id persisted on experiments: hardware_policy = "amd-only-v1".

Supported vs blocked

Supported

x86 / x86_64
AMD CPU
No GPU or AMD GPU only
Windows & Linux x86_64 releases

Blocked

Intel / unknown CPU
NVIDIA or Intel GPU
Mixed GPU vendors
Non-x86 architectures

Exit codes (20–25)

Code	Meaning
`20`	Unsupported architecture
`21`	Intel CPU detected
`22`	NVIDIA GPU detected
`23`	Intel GPU detected
`24`	Unknown CPU vendor
`25`	Unsupported combination (mixed / unknown GPU / other)

There is no production --force bypass. Tests may use the mock-platform feature to inject hardware facts.

Detection

CPU: CPUID leaf 0 vendor string; Linux /proc/cpuinfo and sysinfo fallbacks.
GPU: Windows PCI Enum registry (VEN_xxxx, Display class); Linux /sys/bus/pci class 0x03 — no lspci dependency.
Hot-plug: optimizer / session guards re-check; NVIDIA appearance mid-session → stop, restore managed config, block.

Product surfaces

Surface	Behavior
CLI	Shared pre-dispatch gate; `compatibility` / `hardware` / `amd …` are inspect-only
Desktop	Splash/blocker + `/api/eligibility`; gated APIs return 403 when blocked
SDK	`UnsupportedHardware`, `Kraftverk::open_default()`, `require_supported_hardware()`
Agent	`PrivilegedAgent::start()` + re-check before apply/rollback
Optimizer	Session guard revalidation each search iteration

Inspect-only CLI

kraftverk compatibility   # policy status + reasons (no gate)
kraftverk hardware        # CPUID + PCI inventory (no gate)
kraftverk amd cpu         # Ryzen topology hints (honest / unset when unknown)
kraftverk amd gpu         # AMD GPU list (PCI 0x1002)

Release targets

Official binaries: x86_64 Windows and x86_64 Linux only.
