So jumping in here. I am working on a similar issue, ie on a subsystem that
allow a device to mirror a process address space (or part of it) using its
own mmu and page table.
While i am aiming at providing a generic API, it is not yet fully cook thus
i think having a driver implement its own code in the meantime is something
we have to live with. I am sharing the frustration of Sagi or Haggai on how
hard it is to get any kind of review.
I have not yet reviewed this code but it's nearing the top of on my todo list.
Even thought i am not an authoritative figure in either mm or rdma.
For anyone interested in taking a peak at HMM (subsystem i am working on to
provide same functionality and more) :
