| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If ocrdma_get_pd_num() fails, then we need to free the pd struct we allocated. This was detected by Coverity (CID 1271245).

| * | IB/core: Add per port immutable struct to ib_deviceIra Weiny2015-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As of commit 5eb620c81ce3 "IB/core: Add helpers for uncached GID and P_Key searches"; pkey_tbl_len and gid_tbl_len are immutable data which are stored in the ib_device. The per port core capability flags to be added later are also immutable data to be stored in the ib_device object. In preparation for this create a structure for per port immutable data and place the pkey and gid table lengths within this structure. "get_port_immutable" is added as a mandatory device function to allow the drivers to fill in this data.

* RDMA/ocrdma: Use unsigned for bit indexRasmus Villemoes2015-02-18
| | | | | | | | | | | | | In the expressions idx/32 and idx%32, both idx and 32 have signed type, and unfortunately the C standard prescribes rounding to 0, so unless gcc can prove that idx is non-negative, these cannot be implemented as simple shift respectively mask operations. Help gcc by changing the type of idx to unsigned - this cuts another few instructions from the generated code.

* | RDMA/ocrdma: Do not skip setting deferred_armDevesh Sharma2014-09-19
| | | | | | | | | | | | | | | | | | | | | | | | | | When ib_request_notify_cq() is called for the first time, ocrdma tries to skip setting deffered_arm flag. This may lead CQ to an un-armed state thus never generating a CQ event and leaving consumer hung. This patch removes the part of code that skips setting deferred_arm.
