Hello. We have two kinds of PCIe cards: A1 - based on chip B A2 - based on same chip B but behind PCIe switch
Card A1 work flawlessly in any configuration, but card A2 work flawlessly only if system lack IOMMU or have disabled IOMMU Questions: Do we have to treat card with PCIe switch in special way? How? Where (PCI bridge driver? card's driver?)? Any examples in kernel? Thank you.
