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
