nouveau and kernel GPU VMA management
summary
Nouveau now uses NVIDIA GSP firmware so reclocking works and GPUs run at expected speeds; firmwares are large at 20–30 MB firmwares which forces distro/initramfs changes and messy version churn. A driver-independent GPU VA manager (VM bind API) is upstreamed and replaces per-driver VM hacks, with scheduler and sync fixes merged around kernel 66/67. Userland NVK Vulkan stacks land in Mesa with a new compiler and near-term Vulkan 1.x conformance, though replayable fault handling and sensor reporting remain unfinished.
