Hi all:
This RFC implement packed ring layout. The code were tested with pmd
implement by Jens at
http://dpdk.org/ml/archives/dev/2018-January/089417.html. Minor change
was needed for pmd codes to kick virtqueue since it assumes a busy
polling backend.
Test were done between localhost and guest. Testpmd (rxonly) in guest
reports 2.4Mpps. Testpmd (txonly) repots about 2.1Mpps.
And how does it compare to older ring layout?
No obvious difference.
Vhost itself becomes a bottleneck. I plan to do more aggressive batching
like dpdk on top.
Thanks
