[PATCH 10/21] vhost: support ASID in IOTLB API

2020-12-15 Thread Jason Wang
This patches allows userspace to send ASID based IOTLB message to vhost. This idea is to use the reserved u32 field in the existing V2 IOTLB message. Vhost device should advertise this capability via VHOST_BACKEND_F_IOTLB_ASID backend feature. Signed-off-by: Jason Wang --- drivers/vhost/vdpa.c
