From: Jiayu Hu When the guest memory is hotplugged, the vhost application which enables DMA acceleration must stop DMA transfers before the vhost re-maps the guest memory. This patch is to notify the vhost application of stopping DMA transfers. Signed-off-by: Jiayu Hu --- lib/vhost/vhost_user

[dpdk-dev] [PATCH v4 2/5] vhost: add unsafe API to drain pkts in async vhost

Applications need to stop DMA transfers and finish all the in-flight pkts when in VM memory hot-plug case and async vhost is used. This patch is to provide an unsafe API to drain in-flight pkts which are submitted to DMA engine in vhost async data path. Signed-off-by: Cheng Jiang --- lib/vhost

[dpdk-dev] [PATCH v4 1/5] vhost: fix async vhost ops return type

The async vhost ops callback should return -1 when there are something wrong in the callback, so the return type should be changed into int32_t. The issue in vhost example is also fixed in this patch. Signed-off-by: Cheng Jiang --- examples/vhost/ioat.c | 4 +-- examples/vhost/ioat.h
