Features

• Performance-Tuned Kernel Distributions - Ships a performance-tuned Arch Linux kernel distribution with advanced compiler optimizations and multiple CPU schedulers.
• Handheld Gaming Kernel Patches - Provides kernel patches specifically for Steam Deck and ROG Ally hardware compatibility and gaming performance.
• Multi-Scheduler Selection - Offers BORE, EEVDF, and BMQ schedulers for matching scheduling behavior to interactive or throughput-oriented workloads.
• CPU Schedulers - Provides a custom BORE scheduler that prioritizes interactive tasks to reduce input lag.
• BORE EEVDF BMQ Variants - Provides kernel variants with multiple CPU scheduler options for workload-specific optimization.
• Real-Time Kernel Variants - Provides kernel variants with real-time preemption patches for deterministic, low-latency task scheduling.
• System Performance Optimization - Applies advanced compiler optimizations and multiple CPU schedulers to enhance system responsiveness and throughput.
• NTFS & ZFS Patches - Provides built-in ZFS modules and upstream NTFS driver fixes for improved filesystem reliability.
• Real-Time Performance Profilers - Provides a kernel variant with real-time preemption and the BORE scheduler for time-sensitive applications.
• Userspace Scheduling Frameworks - Supports the sched-ext framework for custom CPU scheduling logic defined entirely in userspace.
• Handheld Hardware Support - Applies kernel patches for Steam Deck and ROG Ally hardware compatibility.
• Profile-Guided Kernel Compilations - Compiles the kernel using Clang Thin LTO and AutoFDO/Propeller profiling to generate more efficient machine code.
• PREEMPT_RT Patches - Provides a kernel variant with PREEMPT_RT patches for deterministic low-latency task scheduling.
• GPU Memory Cgroup Controllers - Implements per-cgroup GPU VRAM limits with hard caps and proportional sharing via the DRM subsystem.
