hardwaredepends

Hardwaredepends is a conceptual specification and accompanying tooling designed to describe hardware requirements alongside software dependencies. It provides a machine-readable way to express constraints on processors, memory, storage, GPUs, I/O devices, firmware, drivers, and other hardware features, enabling safer installation, packaging, and deployment across diverse systems.

The core idea is to treat hardware characteristics as first-class dependencies that can be declared in package manifests or deployment descriptors. A hardwaredepends manifest defines fields such as architecture, memory, storage, processors, devices, device features, and required driver or firmware versions. Validators can compare a target system's capabilities against the manifest, and installers or orchestrators can skip, warn, or adapt installations accordingly.

Format and tooling: The specification proposes a declarative schema that can be expressed in YAML or JSON and parsed by hardwaredepends-aware tools. Typical fields include architecture, required_features, memory_mb, storage_mb, devices with vendor and model, and required_drivers. A separate hardware catalog can map devices to capabilities and driver availability, enabling cross-platform checks.

Applications and impact: Hardwaredepends can be used by operating system installers, container and VM images, package managers, and software stores to prevent incompatible installations. It supports conditional packaging decisions, such as offering alternate builds for non-GPU systems or enabling runtime feature negotiation.

Limitations and status: As a hypothetical standard, hardwaredepends faces compatibility and maintenance challenges across vendors and ecosystems. Real-world use depends on community adoption, tooling support, and alignment with existing hardware identification practices.
