The Radeon™ Raytracing Analyzer (RRA)

The Radeon Raytracing Analyzer is a tool designed to help developers improve the raytracing performance on AMD Radeon 6000 and 7000 series GPU’s. The tool focuses on the visualization of Acceleration Structures, which in our case consist of Bounding Volume Hierarchies. RRA allows the developer to visualize the bounding box hierarchies, and related scene geometries, to quickly identify issues with the bounding volume hierarchies, such as overlapping bounding volumes and sparse geometry layout within bounding volumes. Once identified, the developer can revisit their BVH generation strategy.

This document describes how the Radeon Raytracing Analyzer can be used to examine a bounding volume hierarchy.

  • With the introduction of 25.20-based Linux drivers, the AMDVLK driver is no longer included in the amdgpu-pro driver package. This is a result of the AMDVLK open-source project being discontinued as mentioned here. Instead, the RADV open-source Vulkan® driver is installed by default. Consequently, the Radeon Developer Panel does not support capturing data from Vulkan applications when using these newer driver releases. To analyze Linux Vulkan workloads with Radeon GPU Profiler (RGP), Radeon Raytracing Analyzer (RRA), or Radeon Memory Visualizer (RMV), users can opt for a 25.10-based driver. Alternatively, analysis can be performed using the data capture mechanism integrated within the RADV driver, although this method is not supported by the Radeon Developer Panel. For more information on configuring RADV, refer to the environment variable documentation, specifically the MESA_VK_TRACE_* environment variables which can be utilized for enabling and configuring tracing.
