2016-03-10IB/rdmavt: Clean up distinction between port number and indexDennis Dalessandro1-2/+2
IB core uses 1 relative indexing for ports. All of our data structures use 0 based indexing. Add an inline function that we can use whenever we need to validate a legal value and try to convert a port number to a port index at the entrance into rdmavt. Try to follow the policy that when we are talking about a port from IB core point of view we refer to it as a port number. When port is an index into our arrays refer to it as a port index.

This patch adds rdmavt device structure allocation in rdamvt. The ib_device alloc is now done in rdmavt instead of the driver. Drivers need to tell rdmavt the number of ports when calling. A side of effect of this patch is fixing a bug with port initialization where the device structure port array was allocated over top of an existing one.

Add in a post_send and post_one_send to rdmavt. The ULP will provide a WQE to rdmavt which will then walk and queue each element. Rdmavt will then queue the work to be done in the driver or kick the driver's progress routine. There needs to be a follow on patch which adds in another lock for the head of the queue so that it can be added to and read from in parallel. This will touch protocol handlers and require other changes in the drivers. This will be done separately.

2016-03-10IB/rdmavt: Support creating qps with GFP_NOIO flagMike Marciniszyn1-2/+3
The current code is problematic when the QP creation and ipoib is used to support NFS and NFS desires to do IO for paging purposes. In that case, the GFP_KERNEL allocation within create_qp causes a deadlock in tight memory situations. This fix adds support to create queue pair with GFP_NOIO flag for connected mode only to cleanly fail the create queue pair in those situations. This was previously fixed in qib but needed to get ported to hfi1. This patch handles that for both hardwares in the new rdmavt common layer.

Don't trap flag (i.e. IB_FLOW_ATTR_FLAGS_DONT_TRAP) indicates that QP will receive traffic, but will not steal it. When a packet matches a flow steering rule that was created with the don't trap flag, the QPs assigned to this rule will get this packet, but matching will continue to other equal/lower priority rules. This will let other QPs assigned to those rules to get the packet too. If both don't trap rule and other rules have the same priority and match the same packet, the behavior is undefined. The don't trap flag can't be set with default rule types (i.e. IB_FLOW_ATTR_ALL_DEFAULT, IB_FLOW_ATTR_MC_DEFAULT) as default rules don't have rules after them and don't trap has no meaning here.

Cross-channel operations support is indicated by HCA capability information. The queue pairs can be configured to work as a “sync master queue” or “sync slave queues”. The added flags are: 1. Device capability flag IB_DEVICE_CROSS_CHANNEL for the devices that can perform cross-channel operations. 2. CQ property flag IB_CQ_FLAGS_IGNORE_OVERRUN to disable CQ overrun check. This check is useless in cross-channel scenario. 3. QP property flags to indicate if queues are slave or master: * IB_QP_CREATE_MANAGED_SEND indicates that posted send work requests will not be executed immediately and requires enabling. * IB_QP_CREATE_MANAGED_RECV indicates that posted receive work requests will not be executed immediately and requires enabling. * IB_QP_CREATE_CROSS_CHANNEL declares the QP to work in cross-channel mode.
