The cleaner shader is responsible for clearing the Local Data Store (LDS), Vector General Purpose Registers (VGPRs), and Scalar General Purpose Registers (SGPRs), which helps prevent data leakage and ensures accurate computation results. This update extends cleaner shader support to GFX11.0.0/11.0.2 GPUs, previously available for GFX11.0.3. It enhances security by clearing GPU memory between processes and maintains a consistent GPU state across KGD and KFD workloads.
