IB/pma: Add include file for IBA performance counters definitions

2011-07-19T04:04:35Z

Move the various definitions and mad structures needed for software implementation of IBA PM agent from the ipath and qib drivers into a single include file, which in turn could be used by more consumers. Signed-off-by: Or Gerlitz Signed-off-by: Roland Dreier

IB/core: Add GID change event

2011-07-19T04:04:30Z

Add IB GID change event type. This is needed for IBoE when the HW driver updates the GID (e.g when new VLANs are added/deleted) table and the change should be reflected to the IB core cache. Signed-off-by: Eli Cohen Signed-off-by: Or Gerlitz Signed-off-by: Roland Dreier

RDMA/cma: Add support for netlink statistics export

2011-05-25T20:46:23Z

Add callbacks and data types for statistics export of all current devices/ids. The schema for RDMA CM is a series of netlink messages. Each one contains an rdma_cm_stat struct. Additionally, two netlink attributes are created for the addresses for each message (if applicable). Their types used are: RDMA_NL_RDMA_CM_ATTR_SRC_ADDR (The source address for this ID) RDMA_NL_RDMA_CM_ATTR_DST_ADDR (The destination address for this ID) sockaddr_* structs are encapsulated within these attributes. In other words, every transaction contains a series of messages like: -------message 1------- struct rdma_cm_id_stats { __u32 qp_num; __u32 bound_dev_if; __u32 port_space; __s32 pid; __u8 cm_state; __u8 node_type; __u8 port_num; __u8 reserved; } RDMA_NL_RDMA_CM_ATTR_SRC_ADDR attribute - contains the source address RDMA_NL_RDMA_CM_ATTR_DST_ADDR attribute - contains the destination address -------end 1------- -------message 2------- struct rdma_cm_id_stats RDMA_NL_RDMA_CM_ATTR_SRC_ADDR attribute RDMA_NL_RDMA_CM_ATTR_DST_ADDR attribute -------end 2------- Signed-off-by: Nir Muchtar Signed-off-by: Roland Dreier

RDMA/cma: Pass QP type into rdma_create_id()

2011-05-25T20:46:23Z

The RDMA CM currently infers the QP type from the port space selected by the user. In the future (eg with RDMA_PS_IB or XRC), there may not be a 1-1 correspondence between port space and QP type. For netlink export of RDMA CM state, we want to export the QP type to userspace, so it is cleaner to explicitly associate a QP type to an ID. Modify rdma_create_id() to allow the user to specify the QP type, and use it to make our selections of datagram versus connected mode. Signed-off-by: Sean Hefty Signed-off-by: Roland Dreier

RDMA: Update exported headers list

2011-05-25T20:46:23Z

Various RDMA headers are intended to be exported to userspace, so add them to the headers-y list. Add a (strictly speaking, superfluous) include of to avoid a headers_check warning. Signed-off-by: Roland Dreier

RDMA/cma: Export enum cma_state in

2011-05-25T20:46:22Z

Move cma.c's internal definition of enum cma_state to enum rdma_cm_state in an exported header so that it can be exported via RDMA netlink. Signed-off-by: Nir Muchtar Signed-off-by: Roland Dreier

RDMA: Add netlink infrastructure

2011-05-20T18:46:11Z

Add basic RDMA netlink infrastructure that allows for registration of RDMA clients for which data is to be exported and supplies message construction callbacks. Signed-off-by: Nir Muchtar [ Reorganize a few things, add CONFIG_NET dependency. - Roland ] Signed-off-by: Roland Dreier
