This patch series enables better integration of KFD memory management with the DRM GEM ioctl API. It allow managing virtual address mappings in compute VMs with the GEM_VA ioctl after importing DMABufs exported from KFD into libdrm. This will enable more flexible virtual address management for ROCm user mode, better interoperability between compute and graphics, as well as sharing of memory between processes using DMABufs.
