This patch fixed it by removing the action that release qpc memory in the 'hns_roce_qp_free' function. [Steps to Reproduce] 1. load hns-roce-hw-v2.ko and open smmu 2. run rdma app 3. kill RoCE process [Actual Results] fail [Expected Results] success [Reproducibility] Inevitably [Additional information] Hardware: D06 Firmware: NA Kernel: NA [Resolution] RDMA/hns: Fixs hw access invalid dma memory error To manage notifications about this bug go to: https://bugs.launchpad.net/kunpeng920/+bug/1853990/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
