...d virtio-iommu). This isn't supported by the current OF driver, which expects all endpoints to have an IOMMU. Allow the iommu-map property to have gaps. Relaxing of_map_rid() also allows the msi-map property to have gaps, which is invalid since MSIs always reach an MSI controller. In that case pci_msi_setup_msi_irqs() will return an error when attempting to find the device's MSI domain.

Implement the virtio-iommu driver, following specification v0.8 [1]. Changes since v3 [2]: * Rebase onto v4.20-rc2. Patch 3 now touches drivers/of/base.c instead of drivers/pci/of.c, since the map_rid() function has moved. * Removed the request timeout, that depended on DEBUG. * Other small fixes addressing comments on v3. You can find Linux driver and kvmtool device on my virtio-iommu/v0.8.1

Implement the virtio-iommu driver, following specification v0.9 [1]. Only minor changes since v5 [2]. I fixed issues reported by Michael and added tags from Eric and Bharat. Thanks! You can find Linux driver and kvmtool device on v0.9 branches [3], module and x86 support on virtio-iommu/devel. Also tested with Eric's QEMU device [4].

Implement the virtio-iommu driver, following specification v0.12 [1]. Since last version [2] we've worked on improving the specification, which resulted in the following changes to the interface: * Remove the EXEC flag. * Add feature bit for the MMIO flag. * Change domain_bits to domain_range. Given that there were small changes to patch 5/7, I removed the review and test tags. Please find

Implement the virtio-iommu driver, following specification v0.9 [1]. Since v4 [2] I fixed the issues reported by Eric, and added Reviewed-by from Eric and Rob. Thanks! I changed the specification to fix one inconsistency discussed in v4. That the device fills the probe buffer with zeroes is now a "SHOULD" instead of a "MAY", since it's the only way for the driver to know
