This patch set is to provide an unsafe API to drain in-flight pkts which are submitted to DMA engine in vhost async data path, and notify the vhost application of stopping DMA transfers. And enable it in vhost example. v2: * changed the patch structure Cheng Jiang (2): vhost: add unsafe API to drain pkts in async vhost examples/vhost: handle memory hotplug for async vhost Jiayu Hu (1): vhost: handle memory hotplug for async vhost examples/vhost/main.c | 48 +++++++++++++++++++- examples/vhost/main.h | 1 + lib/vhost/rte_vhost_async.h | 22 +++++++++ lib/vhost/version.map | 3 ++ lib/vhost/vhost_user.c | 9 ++++ lib/vhost/virtio_net.c | 90 +++++++++++++++++++++++++++---------- 6 files changed, 148 insertions(+), 25 deletions(-) -- 2.29.2
