Hi, I am a newbie on the intel-gfx and tries to use the shared virtual memory
which is mentioned in several intel documents (vt-d and Intel-gfx-prm)supported
in the opencl library to share address space betweenCPU and intel integrated
GPU.As far as I know, shared virtual memory is supported as a part of intel
VT-D extensionwith the help of IOMMU and PASID. Although It seems that
intel-gfx repo has the source code related with PASID,the opencl library for
intel-gfx (beignet) doesn't use the any functionsrelated with PAISD nor
IOMMU.It seems that clSVMAlloc is a opencl function for zero copyfollowing the
Intel document,but it doesn't use any functions related with PASID and IOMMU.Is
the current intel-gfx supports the virtual address space sharing thorugh the
IOMMU and PASID? *I am so sorry If I sent this mail to wrong mailing listBest
regardsJaehyuk.
