This series allows NVMe passthrough on aarch64 with 64kB page host. Addresses and sizes of buffers which are VFIO DMA mapped are aligned with the host page size.
nvme_register_buf() path is taken care of in this series but it does not seem to prevent the use case from working. Best Regards Eric This series can be found at: https://github.com/eauger/qemu/tree/nvme_64k_rfc This was tested on ARM only.
