✨ About

aev is a lightweight ultra-fast system fetch focused on low startup latency, minimal overhead, and direct hardware detection.

Written entirely in pure Rust without bloated dependencies.

Designed around:

• ⚡ extremely fast startup time
• 🧠 low-level hardware detection
• 🧼 clean terminal output
• 🖤 minimal aesthetic
• 🧩 lightweight internals
• 🐧 Linux-first design

Unlike traditional fetch tools, aev directly interacts with:

• CPUID instructions
• /proc
• /sys
• PCI device scanning
• atomic cache validation
• threaded information gathering

to reduce abstraction overhead and improve responsiveness.

🔬 Technical Details

aev avoids slow abstractions whenever possible.

It uses:

• __cpuid() and __cpuid_count()
• direct /proc parsing
• direct /sys PCI scanning
• cached GPU and kernel validation
• atomic cache synchronization
• RwLock shared caches
• threaded information gathering

to minimize unnecessary overhead.

GPU detection includes:

• NVIDIA GPU lookup tables
• AMD GPU lookup tables
• Intel GPU lookup tables
• hybrid GPU detection
• PCI fallback detection
• automatic iGPU / dGPU classification
