[PATCH v10 6/8] vfio/type1: check doorbell safety

On x86 IRQ remapping is abstracted by the IOMMU. On ARM this is abstracted by the msi controller. Since we currently have no way to detect whether the MSI controller is upstream or downstream to the IOMMU we rely on the MSI doorbell information registered by the interrupt controllers. In case at l

This patch allows the user-space to retrieve the MSI geometry. The implementation is based on capability chains, now also added to VFIO_IOMMU_GET_INFO. The returned info comprise: - whether the MSI IOVA are constrained to a reserved range (x86 case) and in the positive, the start/end of the aper

[PATCH v10 5/8] vfio: allow reserved msi iova registration

The user is allowed to register a reserved MSI IOVA range by using the DMA MAP API and setting the new flag: VFIO_DMA_MAP_FLAG_MSI_RESERVED_IOVA. This region is stored in the vfio_dma rb tree. At that point the iova range is not mapped to any target address yet. The host kernel will use those iova

[PATCH v10 2/8] vfio/type1: vfio_find_dma accepting a type argument

In our RB-tree we get prepared to insert slots of different types (USER and RESERVED). It becomes useful to be able to search for dma slots of a specific type or any type. This patch introduces vfio_find_dma_from_node which starts the search from a given node and stops on the first node that match

[PATCH v10 4/8] vfio/type1: handle unmap/unpin and replay for VFIO_IOVA_RESERVED slots

Before allowing the end-user to create VFIO_IOVA_RESERVED dma slots, let's implement the expected behavior for removal and replay. As opposed to user dma slots, reserved IOVAs are not systematically bound to PAs and PAs are not pinned. VFIO just initializes the IOVA "aperture". IOVAs are allocated

[PATCH v10 3/8] vfio/type1: implement recursive vfio_find_dma_from_node

This patch handles the case where a node is encountered, matching @start and @size arguments but not matching the @type argument. In that case, we need to skip that node and pursue the search in the node's leaves. In case @start is inferior to the node's base, we resume the search on the left leaf.
