[PATCH net-next v3 00/13] virtio: support packed ring
Hi,
This patch set implements packed ring support in virtio driver.
A performance test between pktgen (pktgen_sample03_burst_single_flow.sh)
and DPDK vhost (testpmd/rxonly/vhost-PMD) has been done, I saw
~30% performance gain in packed ring in this case.
To make this patch set work with below patch set for vhost,
some hacks are needed to set the _F_NEXT flag in indirect
descriptors (this should

[PATCH V3 00/15] Packed virtqueue support for vhost
Hi all:
This series implements packed virtqueues which were described
at [1]. In this version we try to address the performance regression
saw by V2. The root cause is packed virtqueue need more times of
userspace memory accesssing which turns out to be very
expensive. Thanks to the help of 7f466032dc9e ("vhost: access vq
metadata through kernel virtual address"), such overhead cold be
