	sys/dev/pci/virtio.c: revision 1.64
	sys/dev/pci/virtio.c: revision 1.65

Fix dmamap_syncs more; the number of ring elements is vq->vq_num, not
sc->sc_nvqs.

Subtly adjust criteria for notification of Virtio devices in
VIRTIO_F_RING_EVENT_IDX mode.

This fixes stalls in the vioif(4) transmit path that would happen sooner
or later, depending on interface transmit utilization, and were
particularly noticable with a NetBSD guest transmitting to its x86 KVM
host at multi-gigabit speeds.

virtio(4): Use howmany from sys/param.h instead of open-coding it.

howmany will divide by VIRTIO_PAGE_SIZE instead of doing &
~(VIRTIO_PAGE_SIZE - 1), but it's a constant 4096 so this should make
no difference in the compiled output except possibly at -O0.

No functional change intended.

virtio(4): Membar and bus_dmamap_sync audit.

- Don't use membar_* for DMA.

- Sync only the header and payload of the rings separately as needed.
  If we bounce, this avoids large memcpy when we only care about the
  header.

- Sync uring with PREREAD before triggering anything that will return
  data in it.

  => Move uring PREREAD in virtio_enqueue_commit to _before_ updating
     vq->vq_avail->idx, which is the pointat which the DMA read is
     triggered in the `device' (host).

  => Omit needless membar_consumer in virtio_enqueue_commit -- may not
     work with DMA memory, and even if it does, redundant with
     bus_dmamap_sync uring PREREAD here.

  => XXX Does the device/host ever return unsolicited entries in the
     queue, or only solicited ones?  If only solicited ones, the
     PREREAD in virtio_init_vq is redundant.

- Sync uring with POSTREAD before we read from it.  This way the DMA
  read into our buffer has finished before we read from the buffer.

  => Add missing uring POSTREAD in virtio_vq_is_enqueued, between read of
     vq->vq_used_idx and return to caller, so that the caller can
     safely use virtio_dequeue.

  => Add missing uring POSTREADs in virtio_start_vq_intr:
     . between entry from caller and the read of vq->vq_used_idx
     . between the read of vq->vq_used_idx and return to caller,
       so that the caller can safely use virtio_dequeue, just like
       virtio_vq_is_enqueued

  => Move uring POSTREADs in virtio_enqueue_commit to _before_ reading
     vq->vq_used->flags or *vq->vq_avail_event, not after.

- After we write to aring, sync it with PREWRITE.  This way we finish
  writing to our buffer before the DMA write from it.

  => Omit needless PREWRITE in virtio_init_vq -- we do the appropriate
     PREWRITE in virtio_enqueue_commit now.

  => Convert membar_producer to bus_dmamap_sync PREWRITE in
     virtio_enqueue_commit.

  => Omit incorrect aring POSTWRITE in virtio_enqueue_commit -- no need
     because the DMA write may not have completed yet at this point,
     and we already do a POSTWRITE in virtio_vq_is_enqueued.

  => Omit needless membar_producer in virtio_postpone_intr -- may not
     work with DMA memory, and even if it does, redundant with
     bus_dmamap_sync PREWRITE here.

- After xfers to aring have completed, sync it with POSTWRITE.

  => Add missing aring POSTWRITE in virtio_free_vq, in case there are
     paths from virtio_enqueue_commit to here that don't go through
     virtio_is_enqueued.  (If there are no such paths, then maybe we
     should KASSERT(vq->vq_queued == 0) in virtio_free_vq.)

virtio: cosmetics - use (*pfn)(...) syntax.

Some people prefer to call function pointers without an explicit
dereference (that is purely cosmetic in this position), especially to
create faux c++ s->pfn(...) with function pointers in struct members.
Some prefer explicit dereference (that requires parens around it).

(pfn)(...) without dereference but with parens looks odd to both, so
make it conform to one of the established alternatives.

Same object code is generated.

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.

	sys/dev/pci/virtio_pci.c: revision 1.13 (patch)
	(applied to sys/dev/pci/virtio.c)

Ensure MSI-X is disabled if allocation of MSI-X interrupts fail.

The virtio device config space moves out from under us when MSI-X
remains enabled, and/or INTx interrupts are masked if we don't ensure
this.

This un-breaks virtio devices that run out of MSI-X interrupts.
Particularly a problem on uniproc x86, where there are only 8 or 9
vectors available, allowing for only about 4 virtio devices to use
MSI-X.

remove checks for failure after memory allocation calls that cannot fail:

  kmem_alloc() with KM_SLEEP
  kmem_zalloc() with KM_SLEEP
  percpu_alloc()
  pserialize_create()
  psref_class_create()

all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.

Implement softint-based interrupt handling in if_vioif

Softint-based interrupt handling is considered as a future direction
of the (network) device driver architecture in NetBSD. pq3etsec of
ppc is already implemented based on the architecture (unlike pq3etsec,
this change doesn't include softint-based if_start). In this
architecture, a hardware interrupt handler just schedules a softint
and the softint performs actual interrupt processing. It reduces
processing in hardware interrupt context and allows Layer 2 network
stack (e.g., bridge, vlan and even bpf) run in softint context,
which makes it easy to implement fine-grain locking in the layer.

This is an experimental implementation of the architecture in if_viof.

virtio introduces a new flag VIRTIO_F_PCI_INTR_SOFTINT. If a driver
of virtio sets it to sc_flags of virtio_softc, virtio calls
softint_schedule in virtio_intr instead of directly calling the
interrupt handler of the driver.

When VIOIF_SOFTINT_INTR is on, vioif doesn't use the existing softint
(vioif_rx_softint) that is called from vioif_rx_vq_done. Because
vioif_rx_softint already runs in softint context and another softint
isn't needed. This change actually improves performance in some cases.

The feature is disabled by default and enabled when SOFTINT_INTR is
set somewhere (normally in a kernel configuration).

Branch: MAIN

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.
