AMD "Cleaner Shader" Coming For GFX11.0.3 GPUs To Help Ensure User/App Isolation
A new patch posted today for the AMDGPU Linux kernel graphics driver is introducing a 'cleaner shader' explicitly for GFX11.0.3 GPUs like the Radeon 780M integrated graphics to help ensure that there is sufficient data isolation between different workloads running on the GPUs
AMD driver engineer Srinivasan Shanmugam posted the patch on Wednesday for adding this cleaner shader microcode for execution on GFX11.0.3 RDNA3 graphics processors. When the cleaner shader feature is enabled, the AMDGPU driver loads this array into a specific location in the GPU memory. The code patch also confirms the default behavior of just checking for GFX 11.0.3 IP block version and then otherwise not enabling the cleaner shader.
