virtio: Support non-legacy network device and queue

2020-06-08T21:51:36Z

The non-legacy interface always defines num_buffers in the header, regardless of whether VIRTIO_NET_F_MRG_RXBUF, just leaving it unused. We also need to ensure our virtqueue doesn't filter out VIRTIO_F_VERSION_1 during negotiation, as it supports non-legacy transports just fine. This fixes network packet transmission on TinyEMU.

Remove FreeBSD 8 support from virtio.

The sbuf API has evolved since 8, as have many others. The other API sweeps didn't make the changes conditional, so this is now noise.

virtio(4): Expose PNP metadata through newbus

2019-06-04T02:34:59Z

Expose the same fields and widths from both vtio buses, even though they don't quite line up; several virtio drivers can attach to both buses, and sharing a PNP info table for both seems more convenient. In practice, I doubt any virtio driver really needs to match on anything other than bus and device_type (eliminating the unused entries for vtmmio), and also in practice device_type is << 2^16 (so far, values range from 1 to 20). So it might be fine to only expose a 16-bit device_type for PNP purposes. On the other hand, I don't see much harm in overkill here.

Add VirtIO bus config_generation method

2018-02-19T19:28:24Z

VirtIO buses (PCI, MMIO) can provide a generation field so a driver can ensure either a 64-bit or array read was stable. MFC after: 2 weeks

Sync VirtIO IDs with Linux

sys/dev: further adoption of SPDX licensing ID tags.

2017-11-27T14:52:40Z

Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Split the virtio.h header file into multiple files

2014-06-01T18:16:01Z

Reorganize the previous contexts of the file as it is in Linux. The eventual goal is to install the header files and share them between the kernel and bhyve. MFC after: 1 week
