July 2025 — geerlingguy/linux (AMDGPU) delivered two substantive driver-feature improvements with tangible business value. Key changes include: 1) GPU driver reset mechanism improvements and unification across AMDGPU, enabling per-queue resets where applicable and standardizing reset behavior for SR-IOV vs bare-metal; consolidated reset flag handling across JPEG, GC IP blocks and core paths. 2) MMHub client ID mappings and IP discovery reliability: updated client ID mappings for MMHub versions 3.0.1, 3.3, and 4.1.0, and hardened IP discovery (firmware-based IP discovery) to avoid incorrect data and ensure correct client identifiers during page faults. These changes reduce misreports and virtualization issues while improving maintainability.

June 2025 monthly summary focused on delivering extensive firmware updates across AMDGPU components for the NVIDIA/linux-firmware repository, with an emphasis on stability, compatibility, and feature enablement across a broad hardware spectrum.
