February 2026: Implemented a GPU usage observability enhancement in snapd by adding a targeted, read-only system_observe rule that allows listing /proc/[0-9]*/fdinfo. This enables tools like nvtop and resources to obtain per-process GPU metrics (e.g., VRAM and engine usage) for Intel/AMD GPUs, improving observability and troubleshooting. The change is security-conscious, restricting access to fdinfo listing while preserving existing file-read permissions, and validated via local testing with an Intel GPU showing accurate GPU usage data when system_observe is plugged in.

June 2025: Delivered new compute accelerator interface (accel) for snaps within snapd, enabling secure access to compute accelerators. Implemented AppArmor and udev rules and configured auto-connection policies to ensure safe, plug-and-play accelerator usage by snaps. No major bugs fixed this month; focus on feature delivery, security hardening, and groundwork for performance-enabled workloads on hardware accelerators.

April 2025 monthly summary for GenAIInfra: Delivered Ollama LLM backend integration for chatqna on Kubernetes, expanding backend options and deployment configurability. This enables customers to select Ollama as an LLM backend, improving flexibility, scalability, and time-to-market for new capabilities.
