AMD Explores Shared Virtual Memory with DRM_GPUSVM

AMD is working on a proof-of-concept implementation of Shared Virtual Memory (SVM) based on the DRM_GPUSVM framework. The goal is to optimize the management of shared virtual memory between the CPU and GPU.

SVM technology allows CPUs and GPUs to access the same memory area, simplifying data exchange and reducing the need for explicit copies. This can lead to significant performance improvements for workloads that require intense collaboration between CPUs and GPUs, such as machine learning model inference and complex graphics processing.

Using the DRM_GPUSVM framework suggests kernel-level integration, potentially offering efficiency and latency benefits compared to user-space solutions.
