isolation between GPU workloads. The cleaner shader is responsible for<br>
clearing the Local Data Store (LDS), Vector General Purpose Registers<br>
(VGPRs), and Scalar General Purpose Registers (SGPRs), which helps<br>
prevent data leakage and ensures accurate computation results.<br>
<br>
This update extends cleaner shader support to GFX10.1.1/10.1.2 GPUs,<br>
previously available for GFX10.1.10. It enhances security by clearing<br>
GPU memory between processes and maintains a consistent GPU state across<br>
KGD and KFD workloads.<br>
