[RFC PATCH V2 2/2] vhost: device IOTLB API
This patch tries to implement an device IOTLB for vhost. This could be used with for co-operation with userspace(qemu) implementation of DMA remapping. The idea is simple. When vhost meets an IOTLB miss, it will request the assistance of userspace to do the translation, this is done through: - Fill the translation request in a preset userspace address (This address is set through ioctl

[RFC PATCH V2 0/2] basic device IOTLB support
This patch tries to implement an device IOTLB for vhost. This could be used with for co-operation with userspace(qemu) implementation of iommu for a secure DMA environment (DMAR) in guest. The idea is simple. When vhost meets an IOTLB miss, it will request the assistance of userspace to do the translation, this is done through: - Fill the translation request in a preset userspace address (This
