This patchset implement the on demand paging feature using HMM. It
depends on the HMM patchset v9 (previous post (1)). Long term plan
is to replace ODP with HMM allowing to share same code infrastructure
accross different class of devices.
HMM (Heterogeneous Memory Management) is an helper layer for device
that want to mirror a process address space into their own mmu. Main
target is GPU but other hardware, like network device can take also
use HMM.
