[PATCH] libhns: Bugfixes and one debug improvement
by Junxian Huang 28 Apr '25

28 Apr '25

From: Xinghai Cen <cenxinghai(a)h-partners.com> The last commit was found when I created a XRC SRQ in lock-free mode but failed to destroy it because of the refcnt check added in the previous commit. The failure was because the PAD was acquired through ibv_srq->pd in destroy_srq(), while ibv_srq->pd wasn't assigned when the SRQ was created by ibv_create_srq_ex(). So let's assign ibv_srq->pd in the common ibv_icmd_create_srq() , so that drivers can get the correct pd no matter which api the SRQ is created by.

[PATCH v1.1 rdma-core 0/5] Bugfixes and one debug improvement
by Junxian Huang 23 Apr '25

23 Apr '25

The first commit adds some debug logs for lock-free mode so that we can intuitively observe whether the lock-free mode is configured. The following three commits fix some errors. The issue of the last commit was found during the testing of the previous ones, where I created a XRC SRQ in lock-free mode but failed to destroy it because of the refcnt check added in the second commit. The failure was because the PAD was acquired through ibv_srq->pd in destroy_srq(), while ibv_srq->pd wasn't assigned when the SRQ was created by ibv_create_srq_ex().

Perftest: Fix TD lock-free mode not working for SRQ/XRC QP
by Junxian Huang 15 Apr '25

15 Apr '25

From: Guofeng Yue <yueguofeng(a)h-partners.com> When creating SRQ/XRC QP in TD lock-free mode, pass in ctx->pad instead of ctx->pd, otherwise the lock-free won't work. Besides, use ctx->pad directly when creating QP/SRQ since pad is designed to be interchangeable with the usual pd. When lock-free mode is disabled, pad is the exactly the usual pd.
