Re: port-sparc64/57290: qemu-system-sparc64 virtio-blk-pci device doesn't work on NetBSD 10.0 - booting halts

[Mike Russo <mike%PaperSolve.com@localhost>]

That is a shame, one of the reasons I am even trying to use virtio-blk-pci is because the default cmdide driver experiences hangs and locks up the entire VM after a while.  It's not a priority for me, only playing around - but I figure it might be something you want to fix in the future since virtio is quite a popular framework for virtualizaiton and there may be people looking to migrate off older Sun hardware and need sparc64 support.

i tried implmenting this for sparc64 yesterday. it didn't help,
for either the blk or network PRs you filed.

the netbsd-10 version is a hack since there's no way to pass the
relevant feature bit in our virtio APIs there (uint32_t has been
widened to uint64_t in -current.)
