| 2009-04-10 | RDS/IW+IB: Set recv ring low water mark to 1/2 full. | Steve Wise | |
| Currently the recv ring low water mark is 1/4 the depth. Performance measurements show that this limits iWARP throughput by flow controlling the rds-stress senders. Setting it to 1/2 seems to max the T3 performance. I tried even higher levels but that didn't help and it started to increase the rds thread cpu utilization.

| 2009-02-27 | RDS: Add iWARP support | Andy Grover | |
| Support for iWARP NICs is implemented as a separate RDS transport from IB. The code, however, is very similar to IB (it was forked, basically.) so let's keep it in one changeset. The reason for this duplicationis that despite its similarity to IB, there are a number of places where it has different semantics. iwarp zcopy support is still under development, and giving it its own sandbox ensures that IB code isn't disrupted while iwarp changes. Over time these transports will re-converge. Signed-off-by: Andy Grover <andy.grover@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net> | |||
