Subject: [dpdk-dev] [PATCH v2 0/3] Fix Vhost regressions
Date: Tue, 28 Jul 2020 18:50:18 +0200	[thread overview]
Message-ID: <20200728165021.216291-1-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.

The third patch fixes the interrupt regression. I tested it OK
with l3fwd-power use-case, but it has not been confirmed by Intel
QE yet. The fix could be further improved in the future by
introducing a dedicated API in rte_epoll library to update epoll

Thanks to Intel QE team for all the validation work!

Maxime Coquelin (3):
  vhost: fix guest notification setting
  net/vhost: fix queue update
  net/vhost: fix interrupt mode
