Alex Williamson babbf17609 vfio/type1: Chunk contiguous reserved/invalid page mappings ... We currently map invalid and reserved pages, such as often occur from mapping MMIO regions of a VM through the IOMMU, using single pages. There's really no reason we can't instead follow the methodology we use for normal pages and find the largest possible physically contiguous chunk for mapping. The only difference is that we don't do locked memory accounting for these since they're not back by RAM. In most applications this will be a very minor improvement, but when graphics and GPGPU devices are in play, MMIO BARs become non-trivial.
