The patch introduces a new PMD. This PMD is implemented as thin wrapper
of librte_vhost.
PATCH v5 changes:
- Rebase on latest master.
- Fix RX/TX routine to count RX/TX bytes.
- Fix RX/TX routine not to count as error packets if enqueue/dequeue
cannot send all packets.
- Fix if-condition checking for multiqueues.
- Add "static" to pthread variable.
- Fix format.
- Change default behavior not to receive queueing event from driver.
- Split the patch to separate rte_eth_vhost_portid2vdev().
PATCH v4 changes:
- Rebase on latest DPDK tree.
- Fix cording style.
- Fix code not to invoke multiple messaging handling threads.
- Fix code to handle vdev parameters correctly.
- Remove needless cast.
- Remove needless if-condition before rt_free().
PATCH v3 changes:
- Rebase on latest matser
- Specify correct queue_id in RX/TX function.
PATCH v2 changes:
- Remove a below patch that fixes vhost library.
The patch was applied as a separate patch.
- vhost: fix crash with multiqueue enabled
- Fix typos.
(Thanks to Thomas, Monjalon)
- Rebase on latest tree with above bernard's patches.
PATCH v1 changes:
- Support vhost multiple queues.
- Rebase on "remove pci driver from vdevs".
- Optimize RX/TX functions.
- Fix resource leaks.
- Fix compile issue.
- Add patch to fix vhost library.
RFC PATCH v3 changes:
- Optimize performance.
In RX/TX functions, change code to access only per core data.
- Add below API to allow user to use vhost library APIs for a port managed
by vhost PMD. There are a few limitations. See "rte_eth_vhost.h".
- rte_eth_vhost_portid2vdev()
To support this functionality, vhost library is also changed.
Anyway, if users doesn't use vhost PMD, can fully use vhost library APIs.
- Add code to support vhost multiple queues.
Actually, multiple queues functionality is not enabled so far.
RFC PATCH v2 changes:
- Fix issues reported by checkpatch.pl
(Thanks to Stephen Hemminger)
