virtio: Add VirtIO PCI modern (V1) support2021-01-19T04:55:23ZBryan Venteicherbryanv@FreeBSD.org2021-01-19T04:55:23Zurn:sha1:9da9560c4dd3556519cd391a04f0db157dc3c295
Use the existing legacy PCI driver as the basis for shared code
between the legacy and modern PCI drivers. The existing virtio_pci
kernel module will contain both the legacy and modern drivers.
Changes to the virtqueue and each device driver (network, block, etc)
for V1 support come in later commits.
Update the MMIO driver to reflect the VirtIO bus method changes, but
the modern compliance can be improved on later.
Note that the modern PCI driver requires bus_map_resource() to be
implemented, which is not the case on all archs.
The hw.virtio.pci.transitional tunable default value is zero so
transitional devices will continue to be driven via the legacy
driver.

lightly used. Find the proper .m file when we depend on *_if.[ch] in
the srcs line, with seat-belts for false positive matches. This uses
make's path mechanism. A further refinement would be to calculate this
once, and then pass the resulting _MPATH to modules submakes.

Add VirtIO console driver2014-10-23T04:47:32ZBryan Venteicherbryanv@FreeBSD.org2014-10-23T04:47:32Zurn:sha1:6f744ddee48ef123f55831ab9980770bbd667fa1
Support for the multiport feature is mostly implemented, but currently
disabled due to some potential races in the hot plug code paths.

This is a significant rewrite of much of the previous driver; lots of
misc. cleanup was also performed, and support for a few other minor
features was also added.
