From 9814626751de427e99ec9df77d6c29f7668fd105 Mon Sep 17 00:00:00 2001 From: Srinivasan Shanmugam Date: Sat, 4 Jan 2025 14:05:36 +0530 Subject: [PATCH] drm/amdgpu/gfx10: Enable cleaner shader for GFX10.3.2/10.3.4/10.3.5 GPUs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Enable the cleaner shader for GFX10.3.2/10.3.4/10.3.5 GPUs to provide data isolation between GPU workloads. 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 GFX10.3.2/10.3.4/10.3.5 GPUs, previously available for GFX10.3.0. It enhances security by clearing GPU memory between processes and maintains a consistent GPU state across KGD and KFD workloads.
