Subject: [dpdk-dev] [PATCH v4 0/3] Fix Vhost regressions
Date: Wed, 29 Jul 2020 15:36:23 +0200 [thread overview]
Message-ID: <20200729133626.237098-1-maxime.coquelin@redhat.com> (raw)
This series aims at fixing the regressions reported by Intel QE.
I managed to reproduce the issues, and this series fixes them.
The two first patches fix the performance regression. They have
been tested by intel QE which confirms the fix.
Patch 3 aims at fixing interrupt mode.
In this v4, only changes are adding NULL check on the intr handle,
to avoid segfault reproduced with using Virtio-user on the other end
when quitting testpmd. It also add an error log when a valid kickfd
get updated as suggested by David as it should not happen. Minor typos
reported by David are also fixed.
There are still l3fwd-power flooding errors when leaving, but these
were already here in v20.05. This is an issue in the application,
not the PMD driver.
Thanks to Intel QE team for all the validation work!
Maxime
