staging/rdma/hfi1: Remove QSFP_ENABLED from HFI capability mask

2015-10-27T08:16:54+00:00

The QSFP interface code has been running without issues and the flag is
never set to off. This patch removes the QSFP_ENABLED bit from HFI1_CAP.

IB/core: Extend ib_uverbs_create_qp

2015-10-22T03:16:46+00:00

ib_uverbs_ex_create_qp follows the extension verbs
mechanism. New features (for example, QP creation flags
field which is added in a downstream patch) could used
via user-space libraries without breaking the ABI.

IB/hfi1: Add PSM2 user space header to header_install

2015-09-03T19:29:52+00:00

When the hfi1 driver was added a user space header file (hfi1_user.h) was added
to be shared between PSM2 and the driver.  However, the file was not added to
the header install.  Add it now.

IB/core: Add core header changes needed for OPA

2015-08-29T02:54:50+00:00

This patch adds the value of the CNP opcode to the existing list of enumerated
opcodes in ib_pack.h

Add common OPA header definitions for driver
build:
- opa_port_info.h
- opa_smi.h
- hfi1_user.h

Additionally, ib_mad.h, has additional definitions
that are common to ib_drivers including:
- trap support
- cca support

The qib driver has the duplication removed in favor
those in ib_mad.h

IB/core: Add timestamp_mask and hca_core_clock to query_device

2015-06-12T18:49:10+00:00

In order to expose timestamp we need to expose two new attributes in
query_device to be used for CQ completion time-stamping:

timestamp_mask - how many bits are valid in the timestamp, where timestamp
values could be 64bits the most.

hca_core_clock - timestamp is given in HW cycles, the frequency in KHZ units
of the HCA, necessary in order to convert cycles to seconds.

This is added both to ib_query_device and its respective uverbs counterpart.

RDMA/core: Enable the iWarp Port Mapper to provide the actual address of the connecting peer to its clients

2015-05-05T13:18:01+00:00

Add functionality to enable the port mapper on the passive side to provide to its
clients the actual (non-mapped) ip/tcp address information of the connecting peer

1) Adding remote_info_cb() to process the address info of the connecting peer
   The address info is provided by the user space port mapper service when
   the connection is initiated by the peer
2) Adding a hash list to store the remote address info
3) Adding functionality to add/remove the remote address info
   After the info has been provided to the port mapper client,
   it is removed from the hash list

IB/core: Add on demand paging caps to ib_uverbs_ex_query_device

2015-02-18T16:36:26+00:00

Add on-demand paging capabilities reporting to the extended query device verb.

Yann Droneaud writes:

    Note: as offsetof() is used to retrieve the size of the lower chunk
    of the response, beware that it only works if the upper chunk
    is right after, without any implicit padding. And, as the size of
    the latter chunk is added to the base size, implicit padding at the
    end of the structure is not taken in account. Both point must be
    taken in account when extending the uverbs functionalities.
