Subject: [RFC 0/5] NVMe passthrough: Support 64kB page host
Date: Thu, 15 Oct 2020 13:52:47 +0200 [thread overview]
Message-ID: <20201015115252.15582-1-eric.auger@redhat.com> (raw)
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
