Commit Message

Yuval Shaia July 15, 2019, 3:20 p.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.

v0 -> v1:
        * Change reg_mr callback signature instead of adding new callback
        * Add the new API to libibverbs/libibverbs.map.in
v1 -> v2:
        * Do not modify reg_mr signature for version 1.0
        * Add note to man page
v2 -> v3:
        * Rename function to reg_mr_iova (and arg-name to iova)
        * Some checkpatch issues not related to this fix but detected now
                * s/__FUNCTION__/__func
                * WARNING: function definition argument 'void *' should
                  also have an identifier name
v3 -> v4:
        * Fix commit message as suggested by Adit Ranadiv
        * Add support for efa
v4 -> v5:
        * Update PABI
        * Update debian files
v5 -> v6:
        * Move the new API to section in libibverbs/libibverbs.map.in
          (IBVERBS_1.7) as pointed out by Mark Haywood
v6 -> v7:
        *
v7 -> v8:
        * Update also redhat and suse specfiles so now all CI checks in
          github passed.
        * Leon, i have your r-b from v5, appriciate if you can take a look
          again now, with all the latest changes
v8 -> v9:
	* Back to 25 per Jason comment
