Re: VirtIO MMIO for amd64



Following up

I ported the "Linux MPtable bug"-feature found by Colin and
IOAPIC is now detected https://github.com/NetBSD/src/commit/37e57b3a0f464246611a005a350e01e25e091bfe

Nevertheless, the disk IRQ from Firecracker is still not
intercepted (or so it seems); I thought the hang, which
actually happens sys/kern/subr_disk.c:disk_read_sectors/biowait,
might be related to bad/missing VirtIO device features but
I checked on FreeBSD and the features are correctly computed.

Ideas are welcome.
