That doesn't work on systems that have multiple huge page sizes (eg
powerpc). You can compare the
Hi Roland,
I resurrected my first try at the XRC patch set.
All the reference counting and management of XRC RCV QPs is now done in the
core layer.
The low-level driver only contains create, modify, query and destroy methods.
(I also extracted the common parts of mlx4_ib_query_xrc_rcv_qp and
Implement XRC target QPs (xrc rcv qps) for userspace.
The basic verbs are: create/modify/query/destroy.
In addition, added two additional verbs -- register and unregister.
The motivation for register/unregister comes from MPI.
MPI requires XRC receive QPs which are not destroyed when the

Support for XRC RCV-only QP (requested by userspace,
but resides in kernel space).
Implements create_xrc_rcv_qp, modify_xrc_rcv_qp, query_xrc_rcv_qp,
and destroy_xrc_rcv_qp.
Since query_xrc_rcv_qp and query_qp are very similar, the common portions
have been placed in a helper function which is

Can you add the RAW_ETY qp type in this release as well?
To be honest I haven't looked at the iWARP datagram stuff at all. I'm
not sure overloading the RAW_ETY QP type is necessarily the right thing

Thus, usage is:
Either: create/modify/query/destroy_xrc_rcv_qp
Or: create/modify/query/reg/unreg_xrc_rcv_qp
I think the latter usage explains why you added checks to prevent duplicate
registration. Was there a reason not to use Roland's suggestion of dropping
create/destroy and having only
The following patches introduce an updated and renamed version of
the ipath HCA driver which supports the QLogic PCIe QLE SDR, DDR,
and QDR series of HCAs.
Rather than try to patch the ipath driver to include support for QDR,
multiple ports, bug fixes, and many other structual changes, the
