2013-09-03RDMA/ocrdma: Increase STAG array sizeNaresh Gottumukkala3-4/+6
1) Increase STAG Array size. 2) Max inline data size should be set to the same value used during QP creation 3) Set max_sge_rd to zero since we dont support RD transport in our adapters. 4) Max cqes reported in ibv_devinfo should be from QUERY_CONFIG.

2013-09-03RDMA/ocrdma: Dont use PD 0 for userpace CQ DBNaresh Gottumukkala6-40/+339
Create_CQ verb doesn't provide a PD pointer. So, until now we are creating all (both userspace and kernel) CQ DB regions from PD0. This will result in mmapping PD0 to applications. A rogue userspace application can mess things up. Also more serious issues is even the be2net NIC uses PD0. This patch addresses this problem by: 1) Create a PD page for every userspace application when the alloc_ucontext is called. This will be destroyed in dealloc_ucontext. 2) All CQs for that context will use the PD allocated in ucontext. 3) The first create_PD call from application will result in returning the PD address from its ucontext (no new PD will be created). 4) For subsecquent create_pd calls from application, we create new PDs for the application.

There are cases like SRIOV where can get only one MSI-X vector allocated for RoCE. In that case we need to use the vector for both data plane and control plane. We need to use EQ create version V2.

ERROR: "unregister_inet6addr_notifier" [drivers/infiniband/hw/ocrdma/ocrdma.ko] undefined! Fix this by wrapping the inet6 calls in #ifdef IPV6. Also make the ocrdma module depend on (IPV6 || IPV6=n) to forbid the case of modular ipv6 but built-in ocrdma (which can't work, because ocrdma calls ipv6 functions).

2012-05-08RDMA/ocrdma: Don't sleep in atomic notifier handlerSasha Levin2-16/+23
Events sent to ocrdma_inet6addr_event() are sent from an atomic context, therefore we can't try to lock a mutex within the notifier callback. We could just switch the mutex to a spinlock since all it does it protect a list, but I've gone ahead and switched the list to use RCU instead. I couldn't fully test it since I don't have IB hardware, so if it doesn't fully work for some reason let me know and I'll switch it back to using a spinlock.
