Ray Tracing for Adreno GPUs on Turnip - Building Bounded Volume Hierarchy Trees

Learn about the implementation of ray tracing acceleration in the Turnip Vulkan driver through this technical conference talk that explores the driver-agnostic framework added to Mesa. Discover how the Ray Tracing Unit, introduced by Qualcomm on Snapdragon 8 Gen 2, enables Turnip to become the fourth Vulkan driver in Mesa with ray tracing capabilities, following anv, radv, and lavapipe. Gain insights into the GPU-based construction of Bounded Volume Hierarchy (BVH) trees, based on the radv implementation, while examining Qualcomm-specific challenges and potential future developments in this specialized graphics technology domain.
