Subject: Re: [dpdk-dev] [PATCH v3 0/6] vhost: improve ready state
Date: Fri, 17 Jul 2020 01:41:54 +0000
Message-ID: <BYAPR11MB2648D1E48E5D7FD300C0CCB18F7C0@BYAPR11MB2648.namprd11.prod.outlook.com> (raw)
In-Reply-To: <2ab288af-09b2-887a-0061-f097d0a84edb@redhat.com>

Hi Matan,

In our daily regression test, we found this patch set will decrease virtio performance and causes virtio interrupt not working properly in multi queue scenarios.  
Could you help to take a look?
Details in Bugzilla  https://bugs.dpdk.org/show_bug.cgi?id=507, btw, pls use low qemu version(qemu<4.1) to reproduce the second issue since the case blocked by one qemu bug with high qemu version.

BR,
Yinan
