The HIP09 introduces the DCA(Dynamic Context Attachment) feature which supports many RC QPs to share the WQE buffer in a memory pool. If a QP enables DCA feature, the WQE's buffer will not be allocated when creating but when the users start to post WRs. This will reduce the memory consumption when there are too many QPs are inactive.
Please note that we didn't find the right way to get user's configuration, so in #4 we still use environment variable to achieve this. We will be appreciated if anyone can provide some sugggestions.
That is definately not going to work.. It should be some dv thing, dv create qp or a dv customization of the parent domain spring to mind
