net/rds: Handle ODP mr registration/unregistration

2020-01-18T09:48:19+00:00

On-Demand-Paging MRs are registered using ib_reg_user_mr and unregistered with ib_dereg_mr. Signed-off-by: Hans Westgaard Ry Acked-by: Santosh Shilimkar Signed-off-by: Leon Romanovsky

net/rds: Detect need of On-Demand-Paging memory registration

2020-01-16T14:15:25+00:00

Add code to check if memory intended for RDMA is FS-DAX-memory. RDS will fail with error code EOPNOTSUPP if FS-DAX-memory is detected. Signed-off-by: Hans Westgaard Ry Acked-by: Santosh Shilimkar Signed-off-by: Leon Romanovsky

rds: ib: update WR sizes when bringing up connection

2019-11-16T20:59:08+00:00

Currently WR sizes are updated from rds_ib_sysctl_max_send_wr and rds_ib_sysctl_max_recv_wr when a connection is shut down. As a result, a connection being down while rds_ib_sysctl_max_send_wr or rds_ib_sysctl_max_recv_wr are updated, will not update the sizes when it comes back up. Move resizing of WRs to rds_ib_setup_qp so that connections will be setup with the most current WR sizes. Signed-off-by: Dag Moxnes Acked-by: Santosh Shilimkar Signed-off-by: David S. Miller

net/rds: Use DMA memory pool allocation for rds_header

2019-10-03T19:11:08+00:00

Currently, RDS calls ib_dma_alloc_coherent() to allocate a large piece of contiguous DMA coherent memory to store struct rds_header for sending/receiving packets. The memory allocated is then partitioned into struct rds_header. This is not necessary and can be costly at times when memory is fragmented. Instead, RDS should use the DMA memory pool interface to handle this. The DMA addresses of the pre- allocated headers are stored in an array. At send/receive ring initialization and refill time, this arrary is de-referenced to get the DMA addresses. This array is not accessed at send/receive packet processing.
