AMDGPU VRAM patches favor foreground workloads

Pixelcluster’s post lays out a kernel-and-userspace approach for smarter AMDGPU VRAM eviction on Linux, built around dmem cgroups, kernel patches, and helpers like `dmemcg-booster` and `plasma-foreground-booster`. The immediate pitch is better gaming behavior under VRAM pressure, but the same mechanism could be valuable for local AI inference on shared desktop GPUs by protecting llama.cpp or other model workloads from being crowded out by browsers and background apps.

// ANALYSIS

Hot take: this is less a gaming tweak than a general-purpose GPU memory prioritization layer, and that makes it interesting for anyone trying to run local models on a machine that is also a desktop.

–The core idea is to make VRAM eviction aware of process priority via cgroups, so foreground or high-value workloads stay resident longer.
–For local inference, the practical win is freeing VRAM from browsers, Electron apps, and other background clutter before a model falls back to slower memory.
–The setup is still rough: it currently leans on CachyOS/KDE, patched kernels, and extra utilities, so it is not yet a smooth mainstream distro experience.
–The upstream story is incomplete, so anyone adopting this for AI work should treat it as an experimental systems hack, not a stable platform feature.
