IMHO linking interrupt remapping to the iommu is a poor design,
interrupt routing belongs in the irq subsystem, not in the iommu.

In the last Fall Reinette mentioned functional tests of resctrl would
be preferred over selftests that are based on performance measurement.
This series tries to address that shortcoming by adding some functional
