...IOVA - for VM(qemu), when vIOMMU is not enabled, fail early if GPA is out of range - for VM(qemu), when vIOMMU is enabled, determine a valid guest address width Please review. Changes from V1: - do not mandate get_iova_range() for device with its own DMA translation logic and assume a [0, ULLONG_MAX] range - mandate IOVA range only for IOMMU that forcing aperture - forbid the map which is out of the IOVA range in vhost-vDPA Thanks Jason Wang (3): vdpa: introduce config op to get valid iova range vhost: vdpa: report iova range vdpa_sim: implement get_iova_range() drivers/vdpa/vdpa_sim...

FWIW, the talks linked by Mehdi really do talk about these things and why I don't think the really are the correct trade-off. Even if you imagine an unsigned type that doesn't allow wrapping, I think this is a really bad type. The problem is that you have made the most common value of the type (zero in every study I'm aware of) be a boundary condition. Today, it wraps to a huge value

Probably not, since ACCESS_PLATFORM does not exclude the device that depends on the chipset IOMMU to work. So in that case, we should query IOMMU driver instead of vDPA de...

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
