This is the initial patch series for the work of upstreaming the driver and
user level library for SIF, the new Oracle HCA.
These patches are needed to support SIF - Oracle's new Infiniband HCA stack
from user mode. A corresponding patch set for the kernel is needed.
Patch 1 introduces a new ibv_cmd_create_ah_ex under a new .so file version
IBVERBS_1.3 in order to preserve backward binary compatibility with older
provider builds.
We need patch 2 because we have a vendor specific extension to the ibv_reg_mr response,
which breaks if alignment criterias are violated.
Patch 3 is similar to patch 2 except that no provider libs uses this code path
(kernel supported XRC send) until now, so no extra backward compatibility measures
are needed.
Changes since v1:
- Introduce the new ibv_cmd_create_ah_ex as a new version IBVERBS_1.3 in the
map file.
Knut Omang (3):
Add new call ibv_cmd_create_ah_ex which supports extra parameters
Add padding to get proper end alignment of ibv_reg_mr_resp
Provide remote XRC SRQ number in kernel post_send.
