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. The related userspace series is named "libhns: Add support for Dynamic Context Attachment".
Hi Does anyone have an opinion about this patchset, thanks!
