kernelkit

Cross-platform kernel optimization toolkit with Linux fast paths and safe fallbacks.

Quick Start

let features = kernelkit::cpu_features::detect();
println!("AVX2: {}, L1: {}KB", features.avx2, features.l1_size / 1024);

let mmap = kernelkit::mmap::open_read("Cargo.toml")?;
println!("File size: {} bytes", mmap.len());

Features

• mmap with MADV_HUGEPAGE + MADV_SEQUENTIAL hints
• CPU affinity — pin threads to cores or NUMA nodes
• readahead — prefetch files, evict pages after scan
• perf_event — hardware counter reading (cycles, cache misses)
• hugepages — HugePageVec for TLB-friendly allocations
• mlock — lock pattern databases in memory
• binformat — binary file header parsing
• NUMA — allocate on specific NUMA nodes
