UFS has it too right? Ok, the wide margin above ignores UFS, which has a lot of the same issues as EMMC, just a little less cruft. > It's not too late to > change things if necessary... it would be great if you could provide > more of the feedback on this on the TC mailing list. I think the big main issue here is that it just forwards an awkwardly specific concept through virtio. If we want a virtio feature it really needs to stand a lone and be properly documented without referring to external specifications that are not openly available. > > It would be great it you could reach out to the > > wider storage community before taking bad ideas from the eMMC standard > > and putting it into virtio. > > Noted.

At least for linux, yes. _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
