Use explicit methods for setting and querying the information instead.Now that everyone's using iommu-dma, is there any point in bouncing this through the drivers at all? Seems like it would make more sense for the x86 drivers to reflect their private options back to iommu_dma_strict (and allow Intel's caching mode to override it as well), then have iommu_dma_init_domain just test !iommu_dma_strict && domain->ops->flush_iotlb_all.
Indeed. I switch to that. _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
