kernelkit

Part of Santh - open source Rust security and infrastructure tooling. Follow @SanthProject on X.

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
