Commit Message

Yuval Shaia June 13, 2019, 11:09 a.m. UTC 
The virtual address that is registered is used as a base for any address
passed later in post_recv and post_send operations.

On some virtualized environment this is not correct.

A guest cannot register its memory so hypervisor maps the guest physical
address to a host virtual address and register it with the HW. Later on,
at datapath phase, the guest fills the SGEs with addresses from its
address space.
Since HW cannot access guest virtual address space an extra translation
is needed to map those addresses to be based on the host virtual address
that was registered with the HW.
This datapath interference affects performances.

To avoid this, a logical separation between the address that is
registered and the address that is used as a offset at datapath phase is
needed.
This separation is already implemented in the lower layer part
(ibv_cmd_reg_mr) but blocked at the API level.

Fix it by introducing a new API function which accepts an address from
guest virtual address space as well, to be used as offset for later
datapath operations.

Also update the PABI to v25

When will this be pulled in to rdma-core master ?

I can use this API for the shared PD demo app.

Thanks

I was happy with it, but haven't checked every detail yet
