The previous TD lock-free patch introduced ibv_create_cq_ex() to
perftest, but it breaks the provider devices which do not support
this API yet. For these devices calling this API leads to an errno
of EOPNOTSUPP. So add a check of errno, and if it is EOPNOTSUPP,
use ibv_create_cq() as a fallback.

Subject: [PATCH] Perftest: Fix TD lock-free mode not working for QP
|
|
|
|
Fix TD lock-free mode not working for QP When
|
|
creating QP in TD lock-free mode, set attr_ex.pd with ctx->pad instead of
|
|
ctx->pd, otherwise the lock-free won't work.
