Ok, I'm happy to do that instead -- what I struggled with is that I don't have enough knowledge of the various architectures to provide the right default implementation. It should be sufficient for the default to return PAGE_SHIFT, and on Power just override that to return the IOMMU table's page size? Since the only user will be the NVMe driver currently, that should be fine? Sorry for the less-than-ideal patch! -Nish _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
