Modern GPU Drivers: Shifting Responsibilities from Kernel to Firmware and Usermode

Explore a technical conference talk from XDC 2023 that delves into the evolving landscape of GPU driver responsibilities, examining how modern graphics APIs and GPUs are shifting tasks away from kernel drivers to firmware and usermode drivers. Learn about the structural differences in recently submitted DRM drivers compared to their predecessors, and discover the emerging APIs being developed to support modern driver development. Gain practical insights through case studies of two GPU drivers: Panthor (supporting second iteration Mali Valhall GPUs) and PowerVR (supporting Series 6XT and Series A Imagination GPUs). Understand the architectural changes and design principles that are reshaping GPU driver development in this 35-minute presentation delivered by B. Brezillon and D. Krummrich.
