* RDMA/ocrdma: Read ASIC_ID register to select asic_genDevesh Sharma2014-04-031-2/+15
| | | | | | | | | | ocrdma driver selects execution path based on sli_family and asic generation number. This introduces code to read the asic gen number from pci register instead of obtaining it from the Emulex NIC driver.

* RDMA/ocrdma: Increase STAG array sizeNaresh Gottumukkala2013-09-021-1/+1
| | | | | | | | | | | 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.

* RDMA/ocrdma: Dont use PD 0 for userpace CQ DBNaresh Gottumukkala2013-09-021-1/+3
| | | | | | | | | | | | | | | | | | | | | | | 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.

* RDMA/ocrdma: For ERX2 irrespective of Qid, num_posted offset is 24Naresh Gottumukkala2013-09-021-3/+2
| | | | | | | | | | 1) All RQ doorbells are handled by ERX2 and doorbell->num_posted offset is constant to bit offset 24 for ERX2 irrspective of Q id. 2) Fixed RESET to INIT state change (from ERR->RST->INIT->RTR case).

Cache the DB calls, until the QP is moved to RTS state. 2) Add max_rd_sge support to dev->attr. 3) Code cleanup in alloc_pd path.
