The software then returns to the bootloader via the link register. This
allows boards to do their own little bits of firmware setup without
needed to replace the bootloader completely (which is the requirement
for existing firmware support).
The blob is loaded by a callback if and only if doing a linux boot
(similar to the existing write_secondary support).

When a device is detached, clear the suspend bit (PORTSC_SUSPEND)
in the port status register.
The specs are not *that* clear what is supposed to happen in case
a suspended device is unplugged. But the enable bit (PORTSC_PED)
is cleared, and the specs mention setting suspend with enable being
unset is undefined behavior. So clearing them both looks reasonable,
and it actually fixes the reported bug.

1) Even though the QMP wire format spells the tag 'type', the
C code spells it 'kind', requiring some hacks in the generator.
2) The C struct uses an anonymous union, which places all tag
values in the same namespace as all non-variant members. This
leads to spurious collisions if a tag value matches a non-variant

When creating snapshot with the dataplane enabled, the snapshot file gets
not the actual state of virtqueue, because the current state is stored in
VirtIOBlockDataPlane. Therefore, before saving snapshot need to sync
the dataplane vring state to the virtqueue. The dataplane will resume its
work at the next notify virtqueue.
When snapshot loads with loadvm we get a message:

error while loading state for instance 0x0 of device

Drop use of the deprecated virtio_map_sg in virtio core.
Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
Reviewed-by: Igor Mammedov <imammedo@redhat.com>
virtio_map_sg currently fails if one of the entries it's mapping is
contigious in GPA but not HVA address space. Introduce virtio_map which
handles this by splitting sg entries.
This new API generally turns out to be a good idea since it's harder to
misuse: at least in one case the existing one was used incorrectly.
This will still fail if there's no space left in the sg, but luckily max
queue size in use is currently 256, while max sg size is 1024, so we
should be OK even is all entries happen to cross a single DIMM boundary.
Won't work well with very small DIMM sizes, unfortunately:
e.g. this will fail with 4K DIMMs where a single
request might span a large number of DIMMs.
Let's hope these are uncommon - at least we are not breaking things.
Note: virtio-scsi calls virtio_map_sg on data loaded from network, and
validates input, asserting on failure. Copy the validating code here -
it will be dropped from virtio-scsi in a follow-up patch.

The goal is to have debug code always compiled during build.
We standardize all debug output on the following format:
[QOM_TYPE_NAME]reporting_function: debug message
The qemu_log_mask() outputis following the same format as
the above debug.

[PMM: Drop attempt to print the ram_addr of a memory region in
one DPRINTF, which (a) was using the wrong format string so
didn't build on 32-bit and (b) was incorrectly looking at a
private field of a MemoryRegion struct]

We should always go through VirtBoardInfo when we need the memmap.
To avoid using a15memmap directly, in this case, we need to defer
the max-cpus check from class init time to instance init time. In
class init we now use MAX_CPUMASK_BITS for max_cpus initialization,
which is the maximum QEMU supports, and also, incidentally, the
maximum KVM/gicv3 currently supports. Also, a nice side-effect of
delaying the max-cpus check is that we now get more appropriate
error messages for gicv2 machines that try to configure more than
123 cpus. Before this patch it would complain that the requested
number of cpus was greater than 123, but for gicv2 configs, it
should complain that the number is greater than 8.

Currently, if the kernel does not have live migration API, the migration
will still be attempted, but vGIC save/restore functions will just not do
anything. This will result in a broken machine state.
This patch fixes the problem by adding migration blocker if kernel API is
not supported.

Guest OS may issue VMXNET3_CMD_GET_STATS even before device was
activated (for example in linux, after insmod but prior net-dev open).
Accessing shared descriptors prior device activation is illegal as the
VMXNET3State structures have not been fully initialized.
As a result, guest memory gets corrupted and may lead to guest OS
crashes.
Fix, by not filling the stats descriptors if device is inactive.
