Subject: [PATCH 2/4] libhns: Fix the owner bit error of sq in new io
|
||
|
|
|
||
|
|
driver inclusion
|
||
|
|
category: bugfix
|
||
|
|
bugzilla: https://gitee.com/src-openeuler/rdma-core/issues/I7A5Y5
|
||
|
|
|
||
|
|
---------------------------------------------------------------
|
||
|
|
|
||
|
|
The code does not use the head position of sq to set the owner bit,
|
||
|
|
but uses the head after adding 1 to cause an owner bit error. When
|
||
|
|
the wqe queue has not been flipped, the hardware has flipped based
|
||
|
|
on the owner bit judgment, resulting in failure to obtain wqe,
|
||
|
|
unable to send, and unable to generate cqe. This patch will set the
|
||
|
|
onwer bit ahead of time before the head value increases.
|
||
|
|
|
||
|
|
Fixes: 36446a56eea5 ("libhns: Extended QP supports the new post send mechanism")
