Subject: virtio "transitional devices"?
Date: Sun, 05 Sep 2021 13:47:48 +0000 [thread overview]
Message-ID: <16fad6ffd7af05706571453114a8c173@unixzen.com> (raw)
Could someone explain to me what virtio "transitional devices" are?
https://docs.oasis-open.org/virtio/virtio/v1.1/cs01/virtio-v1.1-cs01.html#x1-1020002
Are "Transitional devices" pre-1.0 specification?
Haiku's virtio driver (PCI) is looking for PCIID Devices 0x1000-0x103F
I've noticed qemu-6.1.0 has begun to offer PCI DeviceID 0x1040-0x107F to
the operating system breaking our virtio drivers.
Expanding our search range to 0x1040+ seems to solve the issues and gives
us a working virtio driver, but I feel like we should be checking for
other differences.
Has something changed in recent qemu's around virtio? I don't see anything
documented in the release notes.
