| 169 | * Quoting 10.3.1 Queue Pair and EE Context States: |
| 170 | * |
| 171 | * Note, for QPs that are associated with an SRQ, the Consumer should take the |
| 172 | * QP through the Error State before invoking a Destroy QP or a Modify QP to the |
| 173 | * Reset State. The Consumer may invoke the Destroy QP without first performing |
| 174 | * a Modify QP to the Error State and waiting for the Affiliated Asynchronous |
| 175 | * Last WQE Reached Event. However, if the Consumer does not wait for the |
| 176 | * Affiliated Asynchronous Last WQE Reached Event, then WQE and Data Segment |
| 177 | * leakage may occur. Therefore, it is good programming practice to tear down a |
| 178 | * QP that is associated with an SRQ by using the following process: |
| 179 | * |
| 180 | * - Put the QP in the Error State |
| 181 | * - Wait for the Affiliated Asynchronous Last WQE Reached Event; |
| 182 | * - either: |
| 183 | * drain the CQ by invoking the Poll CQ verb and either wait for CQ |
| 184 | * to be empty or the number of Poll CQ operations has exceeded |
| 185 | * CQ capacity size; |
| 186 | * - or |
| 187 | * post another WR that completes on the same CQ and wait for this |
| 188 | * WR to return as a WC; |
| 189 | * - and then invoke a Destroy QP or Reset QP. |
| 190 | * |
| 191 | * We use the second option and wait for a completion on the |
Michael S. Tsirkin | ec56dc0 | 2007-05-28 14:37:27 +0300 | [diff] [blame] | 192 | * same CQ before destroying QPs attached to our SRQ. |
