HMM (Heterogeneous Memory Management) =

Use Cases

• pcie/ccix endpoint side memory pools
• embedded soc e.g. dedicated media buffer alloc pool

zone device and memory hotplug (on arm64)

• arch pte devmap bit options (mair bits, pte_none?, pte_special?)
• device pluggable private and public memory

hmm address space mirroring w/ rproc

• tie into vfio-map shmem model w/ remoteproc instances?
• could we somehow do better than dma migration w/ pgtable remapping?
• (opt.) tie into vfio-bind shmem model needs intg. iommu fault handling
