mlelstv | Fix 32bit overflow when calculating balloon size.
Don't make uvm_pglistalloc wait, it will wait forever. Instead rely on
the retries by this driver. This also allows to cancel the request.
Increase inflate speed by factor 10 (same as deflate).

yamaguchi | Added functions to set interrupt handler and index into virtqueue

yamaguchi | Set virtqueues in virtio_child_attach_finish
The number of virtqueue maybe change in a part of VirtIO devices
(e.g. vioif(4)). And it is fixed after negotiation of features.
So the configuration is moved into the function.

virtio: use the new syntax for snprintb(3) format strings.
The old syntax is limited to 32 bits only (and has 1-based bit numbers
which is rather incovenient too).

reinoud | Add VirtIO PCI v1.0 attachments and fix the drivers affected.
The vioif, ld, scsi, viornd and viomb devices were adjusted when needed and
tested both in legacy 0.9 and v1.0 attachments trough PCI on amd64, sparc64,
aarch64 and aarch64-eb. ACPI/FDT attachments also tested on
aarch64/aarch64-eb.
Known issues
* viomb on aarch64 works only with ACPI/FDT attachment but not with PCI
attachment. PCI and ACPI/FDT attachment works on aarch64-eb.
* virtio on sparc64 attaches but is it not functioning though not a
regression.

reinoud | Fix for virtios viomb memory balloon driver. The inflate_done() and
deflate_done() issued a wrong extent to bus_dmamap_sync() giving rise to
panics on aarch64s mmio backend.

jdolecek | branches: 1.8.12;
reorganize the attachment process for virtio child devices, so that
more common code is shared among the drivers, and it's possible for
the drivers to be correctly dynamically loaded; forbid direct access
to struct virtio_softc from the child driver code

Modularize the ld driver and all of its attachments. Ensure that all
parents are capable of rescan (or otherwise provide a means of attaching
children post-initialization).

Introduce VIRTIO_F_PCI_INTR_MPSAFE for virtio
It is set by a child driver, e.g., if_vioif. If set, virtio sets

Import of the virtio driver written by MINOURA Makoto <minoura@netbsd.org>
with minor changes to make it compile an run on -current. This driver
speeds up disk and network access in virtual environments like KVM.
Enabled on i386 and amd64. Tested with a CentOS 5.7 x86_64 host.
See http://ozlabs.org/~rusty/virtio-spec/virtio.pdf for the specification.

Set virtqueues in virtio_child_attach_finish
The number of virtqueue maybe change in a part of VirtIO devices
(e.g. vioif(4)). And it is fixed after negotiation of features.
So the configuration is moved into the function.
viocon(4): fix not to allocate unused virtqueue
viocon(4) allocates 4 virtqueues but it only uses 2 (0 and 1) queues.
Added functions to set interrupt handler and index into virtqueue
Added check of pointer for allocated memory before release of resource
Setup virtqueues after registering them to virtio_softc
restore fetch of qsize.
Mark as MPSAFE.
virtio(4): Avoid name collision with global intrhand on sparc64.
Pacifies -Werror=shadow.
No functional change intended.
Use PRIuBUSSIZE to print bus_size_t variables.
virtio(4): Fix sizing of virtqueue allocation.
vq->vq_avail[0].ring is a zero-length array, and thus sizeof is zero;
likewise vq->vq_used[0].ring.
Use vq->vq_avail[0].ring[0] and vq->vq_used[0].ring[0] to fix this
and restore the previous allocation sizing logic.
XXX We shouldn't use zero-length arrays here -- they are asking for
trouble like this, and C99 has a standard way to express what we're
actually trying to get at it, flexible array members.
PR kern/57304
virtio(4): Use flexible array members, not zero-length arrays.
This enables the compiler to detect sizeof mistakes like
PR kern/57304.
Use descriptor chain for free slots instead of vq_entry list
Descriptors can be chained by themself. And descriptors added to
avail ring or used ring are already chained. But it was not used
for unused descriptors and another linked list structure named
vq_entry was used.
The chain is also used for unused descriptors to make virtio(4)
simpler.
Added flags to store status of attaching a virtio device
This prevents a panic on reboot after a virtio device had called
virtio_child_attach_failed().
Fix wrong variable names
This fixes build errors in virtio_mmio.c
