RDMA/hns: Update the kernel header file of hns

2019-01-25T16:55:48Z

The hns_roce_ib_create_srq_resp is used to interact with the user for data, this was open coded to use a u32 directly, instead use a properly sized structure. Fixes: c7bcb13442e1 ("RDMA/hns: Add SRQ support for hip08 kernel mode") Signed-off-by: Lijun Ou Signed-off-by: Jason Gunthorpe

RDMA/vmw_pvrdma: Return the correct opcode when creating WR

2019-01-11T00:00:28Z

Since the IB_WR_REG_MR opcode value changed, let's set the PVRDMA device opcodes explicitly.

IB/core: Move query port to ioctl

2018-12-20T22:18:24Z

Add a method for query port under the uverbs global methods. Current ib_port_attr struct is passed as a single attribute and port_cap_flags2 is added as a new attribute to the function. Signed-off-by: Michael Guralnik Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/nldev: Expose port_cap_flags2

2018-12-20T22:18:24Z

port_cap_flags2 represents IBTA PortInfo:CapabilityMask2. The field safely extends the RDMA_NLDEV_ATTR_CAP_FLAGS operand as it was exported as 64 bit to allow this kind of extension. Signed-off-by: Michael Guralnik Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

IB/uverbs: Add support to advise_mr

2018-12-18T22:19:46Z

Add new ioctl method for the MR object - ADVISE_MR. This command can be used by users to give an advice or directions to the kernel about an address range that belongs to memory regions. A new ib_device callback, advise_mr(), is introduced here to suupport the new command. This command takes the following arguments: - pd: The protection domain to which all memory regions belong - advice: The type of the advice * IB_UVERBS_ADVISE_MR_ADVICE_PREFETCH - Pre-fetch a range of an on-demand paging MR * IB_UVERBS_ADVISE_MR_ADVICE_PREFETCH_WRITE - Pre-fetch a range of an on-demand paging MR with write intention - flags: The properties of the advice * IB_UVERBS_ADVISE_MR_FLAG_FLUSH - Operation must end before return to the caller - sg_list: The list of memory ranges - num_sge: The number of memory ranges in the list - attrs: More attributes to be parsed by the provider Signed-off-by: Moni Shoua Reviewed-by: Guy Levi Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/uverbs: Add an ioctl method to destroy an object

2018-12-18T21:59:57Z

Add an ioctl method to destroy the PD, MR, MW, AH, flow, RWQ indirection table and XRCD objects by handle which doesn't require any output response during destruction. Signed-off-by: Parav Pandit Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA/uverbs: Add a method to introspect handles in a context

2018-12-18T21:54:54Z

Introduce a helper function gather_objects_handle() to copy object handles under a spin lock. Expose these objects handles via the uverbs ioctl interface. Signed-off-by: Jason Gunthorpe Signed-off-by: Parav Pandit Signed-off-by: Leon Romanovsky

RDMA/uverbs: Implement an ioctl that can call write and write_ex handlers

2018-12-18T19:12:48Z

Now that the handlers do not process their own udata we can make a sensible ioctl that wrappers them. The ioctl follows the same format as the write_ex() and has the user explicitly specify the core and driver in/out opaque structures and a command number. This works for all forms of write commands.

Merge branch 'mlx5-packet-credit-fc' into rdma.git

2018-12-07T20:25:12Z

Danit Goldberg says: Packet based credit mode Packet based credit mode is an alternative end-to-end credit mode for QPs set during their creation. Credits are transported from the responder to the requester to optimize the use of its receive resources. In packet-based credit mode, credits are issued on a per packet basis. The advantage of this feature comes while sending large RDMA messages through switches that are short in memory. The first commit exposes QP creation flag and the HCA capability. The second commit adds support for a new DV QP creation flag. The last commit report packet based credit mode capability via the MLX5DV device capabilities. * branch 'mlx5-packet-credit-fc': IB/mlx5: Report packet based credit mode device capability IB/mlx5: Add packet based credit mode support net/mlx5: Expose packet based credit mode Signed-off-by: Jason Gunthorpe
