Subject: [Qemu-devel] [PATCH V8 9/9] virtio: increase the queue limit to 1024
Date: Fri, 29 May 2015 14:15:32 +0800 [thread overview]
Message-ID: <1432880132-28477-10-git-send-email-jasowang@redhat.com> (raw)
In-Reply-To: <1432880132-28477-1-git-send-email-jasowang@redhat.com>
Increase the queue limit to 1024. But virtio-ccw and s390-virtio won't
support this, this is done through failing device_plugged() for those
two transports if the number of virtqueues is greater than 64.
