Most mainstream Linux distributions are still solving the problems of 2010. We have rock-solid stability and great package managers, but when a system starts lagging, the OS acts as a passive victim. You open top, see a random process eating CPU, and kill it manually.
I'm currently architecting a completely new Linux distribution from scratch, and I want to validate the core MVP with the community.
The Mission: Your hardware performs as if it were newer.
The Target: A 5-year-old laptop should feel incredibly fast and responsive, and the user shouldn't need to know why.
The Core Concept: Aggressive, eBPF-Driven Self-Healing
Instead of relying on the standard fair-share Linux schedulers (like CFS or EEVDF), this distro shifts to an unfair model by design. It prioritizes the user's immediate UI responsiveness above all else, using eBPF as the telemetry and enforcement engine.
It works on three pillars:
Explainable Telemetry: Using eBPF kprobes and tracepoints with near-zero overhead to monitor CPU wakeups, syscalls, and page faults. Instead of just showing "High CPU," the OS knows contextually what is causing the bottleneck.
The Userspace Brain: A fast controller daemon that polls eBPF maps in real-time. It acts like an autonomous SRE for your local machine.
Dynamic Enforcement: If a background daemon or a rogue browser tab starts aggressively waking up the CPU or thrashing memory, the system doesn't just log it—it acts. It dynamically throttles, freezes (via cgroups), or aggressively pages out the offending process to protect the active workspace.
Essentially, I want to bring mobile-style (iOS/Android) aggressive application lifecycle management to the traditional Linux desktop, driven by real-time kernel observability.
The Brutal Engineering Realities
I know this isn't magic, and I'm anticipating some massive architectural hurdles:
The Observer Effect: Attaching BPF programs to every syscall or context switch on older hardware could introduce more overhead than it saves. Telemetry will need dynamic thresholding and sampling.
Legacy App Freezing: Unlike mobile apps, traditional X11/Wayland desktop apps aren't designed to be randomly suspended. Freezing their cgroups might cause dropped network sockets, corrupted data, or crashes.
I'd love your thoughts:
Before I get too deep into the userspace controller logic, I want to hear from people who have fought these battles.
Has anyone experimented with using eBPF for active, aggressive desktop resource management?
What are the massive blind spots in trying to suspend/resume standard Linux desktop applications?
Is there an existing project trying to solve this specific "explainability" gap on the desktop?
Let me know what you think.
