IB/core: Add subnet prefix to port info

2016-03-21T20:34:06+00:00

The subnet prefix is a part of the port_info MAD returned and should be available at the ib_port_attr struct. We define it here and provide a default implementation in case the hardware driver does not provide one. The subnet prefix is required when creating the address vector to access the SA in networks where GRH must be used. Signed-off-by: Eli Cohen Reviewed-by: Or Gerlitz Signed-off-by: Doug Ledford

IB/core: trivial prink cleanup.

2016-03-03T15:20:25+00:00

1. Replaced printk with appropriate pr_warn, pr_err, pr_info. 2. Removed unnecessary prints around memory allocation failure which are not required, as reported by the checkpatch script. Signed-off-by: Parav Pandit Reviewed-by: Haggai Eran Reviewed-by: Sagi Grimberg Signed-off-by: Doug Ledford

IB/core: Fix missed clean call in registration path

2016-03-01T01:41:47+00:00

In case of failure returned from query function in IB device registration, we need to clean IB cache which was missed. This change fixes it.

IB/core: Add gid_type to gid attribute

2015-12-23T15:35:10+00:00

In order to support multiple GID types, we need to store the gid_type with each GID. This is also aligned with the RoCE v2 annex "RoCEv2 PORT GID table entries shall have a "GID type" attribute that denotes the L3 Address type". The currently supported GID is IB_GID_TYPE_IB which is also RoCE v1 GID type. This implies that gid_type should be added to roce_gid_table meta-data.

IB/core: Remove ib_query_device

2015-12-22T22:01:40+00:00

The copy of the attributes present on the device is now used by all consumers except for uverbs in case of serving user-space query, where dev->query_device is called. Signed-off-by: Or Gerlitz Signed-off-by: Doug Ledford

IB/core: Save the device attributes on the device structure

2015-12-22T19:39:00+00:00

This way both the IB core and upper level drivers can access these cached device attributes rather than querying or caching them on their own. Signed-off-by: Ira Weiny Signed-off-by: Or Gerlitz Signed-off-by: Doug Ledford

IB: add a proper completion queue abstraction

2015-12-11T22:10:43+00:00

This adds an abstraction that allows ULPs to simply pass a completion object and completion callback with each submitted WR and let the RDMA core handle the nitty gritty details of how to handle completion interrupts and poll the CQ. In detail there is a new ib_cqe structure which just contains the completion callback, and which can be used to get at the containing object using container_of. It is pointed to by the WR and WC as an alternative to the wr_id field, similar to how many ULPs already use the field to store a pointer using casts. A driver using the new completion callbacks allocates it's CQs using the new ib_create_cq API, which in addition to the number of CQEs and the completion vectors also takes a mode on how we poll for CQEs. Three modes are available: direct for drivers that never take CQ interrupts and just poll for them, softirq to poll from softirq context using the to be renamed blk-iopoll infrastructure which takes care of rearming and budgeting, or a workqueue for consumer who want to be called from user context. Thanks a lot to Sagi Grimberg who helped reviewing the API, wrote the current version of the workqueue code because my two previous attempts sucked too much and converted the iSER initiator to the new API.

IB/core: Expose and rename ib_find_cached_gid_by_port cache API

2015-10-22T03:48:17+00:00

Sometime consumers might want to search for a GID in a specific port. For example, when a WC arrives and we want to search the GID that matches that port - it's better to search only the relevant port. Exposing and renaming ib_cache_gid_find_by_port in order to match the naming convention of the module. Signed-off-by: Matan Barak Signed-off-by: Doug Ledford

IB/core: Add netdev and gid attributes paramteres to cache

2015-10-22T03:48:17+00:00

Adding an ability to query the IB cache by a netdev and get the attributes of a GID. These parameters are necessary in order to successfully resolve the required GID (when the netdevice is known) and get the Ethernet L2 attributes from a GID.
