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

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.

Fake mode sense data for illegal targets. qemu reports 256 targets...

fix the status return.
--
Use SCSIPI_CHAN_NOSETTLE.
--
vioscsi_req_get()/virtio_enqueue_prep() failing is actually perfectly
normal - observed failures included 10, 27, 61 in-flight commands,
so probably depends on particular command mix; return with
XS_RESOURCE_SHORTAGE rather then panic
do vioscsi_req_put() when initial bus_dmamap_load() fails, as suggested
by the XXX; the vq_done hook is called by virtio, but in that case we
never get to commit the request to it
--
react on ADAPTER_REQ_SET_XFER_MODE so that we set tagged queuing
pass tag type and set id

FILE REMOVED

file virtioreg.h was added on branch netbsd-5 on 2012-01-25 21:18:15 +0000

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.
