RadeonSI Lands Shared Virtual Memory "SVM" Support For Mesa 25.2
Adding to the many graphics driver features to look forward to with next quarter's Mesa 25.2 release is now Shared Virtual Memory (SVM) support for the RadeonSI Gallium3D driver.
SVM also provides memory model consistency guarantees for greater coherency. Back in May the Mesa Rust-based Rusticl OpenCL driver merged support for SVM and since then Red Hat engineer Karol Herbst took to working on SVM support for the Intel Iris Gallium3D and AMD RadeonSI Gallium3D drivers for supporting this functionality. This merge gets that OpenCL 2.0 coarse-grained buffer SVM working on RadeonSI and exposing cl_ext_buffer_device_address.
