| Doc Text: |
A flaw was found in the Linux kernel's `drm/amdgpu/jpeg` component, specifically within the JPEG v3.0 ring. This component does not support 64-bit user fence writes. Consequently, any command submissions (CS) that attempt to use 64-bit user fences will be rejected, leading to a functional limitation or denial of service for applications relying on this feature.
