If the vhost-user-blk daemon provides only one virtqueue, but device was
added with several queues, then QEMU will send more VHOST-USER command
than expected by daemon side. The vhost_virtqueue_start() routine
handles such case by checking the return value from the
virtio_queue_get_desc_addr() function call. Add the same check to the
vhost_dev_set_log() routine.

vhost-user devices can get a disconnect in the middle of the VHOST-USER
handshake on the migration start. If disconnect event happened right
before sending next VHOST-USER command, then the vhost_dev_set_log()
call in the vhost_migration_log() function will return error. This error
will lead to the assert() and close the QEMU migration source process.
For the vhost-user devices the disconnect event should not break the
migration process, because:
- the device will be in the stopped state, so it will not be changed
during migration
- if reconnect will be made the migration log will be reinitialized as
part of reconnect/init process:

Update the vhost-user-blk device with the internal started_vu field which
will be used for initialization (vhost_user_blk_start) and clean up
(vhost_user_blk_stop). This additional flag in the VhostUserBlk structure
will be used to track whether the device really needs to be stopped and
cleaned up on a vhost-user level.
The disconnect event will set the overall VHOST device (not vhost-user) to
the stopped state, so it can be used by the general vhost_migration_log
routine.
Such approach could be propogated to the other vhost-user devices, but
better idea is just to make the same connect/disconnect code for all the
vhost-user devices.

To speed up the memory mapping updating between vhost-vDPA and vDPA
device driver, this patch passes the IOTLB batching flags via IOTLB
API. Two new flags was introduced, VHOST_IOTLB_BATCH_BEGIN is a hint
that a bathced IOTLB updating may be initiated from the
userspace. VHOST_IOTLB_BATCH_END is a hint that userspace has finished
the updating:
VHOST_IOTLB_BATCH_BEGIN
VHOST_IOTLB_UPDATE/VHOST_IOTLB_INVALIDATE
...
VHOST_IOTLB_BATCH_END
Vhost-vDPA can then know that all mappings has been set and can do
optimization like passing all the mappings to the vDPA device driver.

because of the hole after type field. Refer kernel commit
("429711aec282 vhost: switch to use new message format") for more
information.
To enable this feature, qemu need to use a new ioctl
VHOST_SET_BACKEND_FEATURE with VHOST_BACKEND_F_IOTLB_MSG_V2 bit. A new
vhost setting backend features ops was introduced. And when we try to
set features for vhost dev, we will examine the support of new IOTLB
format and enable it. This process is total transparent to guest,
which means we can have different IOTLB message type in src and dst
during migration.
The conversion of IOTLB message is straightforward, just check the
type and behave accordingly.

clang's C11 atomic_fetch_*() functions only take a C11 atomic type
pointer argument. QEMU uses direct types (int, etc) and this causes a
compiler error when a QEMU code calls these functions in a source file
that also included <stdatomic.h> via a system header file:
$ CC=clang CXX=clang++ ./configure ... && make
../util/async.c:79:17: error: address argument to atomic operation must be a pointer to _Atomic type ('unsigned int *' invalid)
Avoid using atomic_*() names in QEMU's atomic.h since that namespace is
used by <stdatomic.h>. Prefix QEMU's APIs with 'q' so that atomic.h
and <stdatomic.h> can co-exist. I checked /usr/include on my machine and
searched GitHub for existing "qatomic_" users but there seem to be none.
This patch was generated using:

A number of iov_discard_front/back() operations are made by
virtio-crypto. The elem->in/out_sg iovec arrays are modified by these
operations, resulting virtqueue_unmap_sg() calls on different addresses
than were originally mapped.
This is problematic because dirty memory may not be logged correctly,
MemoryRegion refcounts may be leaked, and the non-RAM bounce buffer can
be leaked.
Take a copy of the elem->in/out_sg arrays so that the originals are
preserved. The iov_discard_undo() API could be used instead (with better
performance) but requires careful auditing of the code, so do the simple
thing instead.

Fuzzing discovered that virtqueue_unmap_sg() is being called on modified
req->in/out_sg iovecs. This means dma_memory_map() and
dma_memory_unmap() calls do not have matching memory addresses.

void address_space_unmap(AddressSpace *as, void *buffer, hwaddr len,
bool is_write, hwaddr access_len)

if (buffer != bounce.buffer) {
^^^^^^^^^^^^^^^^^^^^^^^
A modified iov->iov_base is no longer recognized as a bounce buffer and
the wrong branch is taken.
There are more potential bugs: dirty memory is not tracked correctly and
MemoryRegion refcounts can be leaked.
Use the new iov_discard_undo() API to restore elem->in/out_sg before
virtqueue_push() is called.

When debugging QEMU it is often useful to put a breakpoint on the
error_setg_internal method impl.
Unfortunately the object_property_add / object_class_property_add
methods call object_property_find / object_class_property_find methods
to check if a property exists already before adding the new property.
As a result there are a huge number of calls to error_setg_internal
on startup of most QEMU commands, making it very painful to set a
breakpoint on this method.
Most callers of object_find_property and object_class_find_property,
however, pass in a NULL for the Error parameter. This simplifies the
methods to remove the Error parameter entirely, and then adds some
new wrapper methods that are able to raise an Error when needed.

The documentation on g_byte_array_free()

says:
> Returns
>
> the element data if free_segment is FALSE, otherwise NULL. The element
> data should be freed using g_free().
Because we currently call g_byte_array_free() with free_segment=TRUE, we
end up passing data=NULL to fw_cfg_add_file().
On the plus side, fw_cfg_data_read() and fw_cfg_dma_transfer() both deal
with NULL data gracefully: QEMU does not crash when the guest reads such
an item, the guest just gets a properly sized, but zero-filled blob.
However, the bug breaks UEFI HTTPS boot, as the IANA_TLS_CIPHER array,
generated otherwise correctly by the "tls-cipher-suites" object, is in
effect replaced with a zero blob.
Fix the issue by passing free_segment=FALSE to g_byte_array_free():
- the caller (fw_cfg_add_from_generator()) temporarily assumes ownership
of the generated byte array,
- then ownership of the byte array is transfered to fw_cfg, as
fw_cfg_add_file() links (not copies) "data" into fw_cfg.

misc: aspeed_scu: Update AST2600 silicon id register
hw/arm/aspeed: Add machine properties to define the flash models
hw/arm/aspeed: Map the UART5 device unconditionally
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
Aspeed have released an updated datasheet (v7) containing the silicon id
for the AST2600 A2. It looks like this:
SCU004 SCU014
AST2600-A0 0x05000303 0x05000303
AST2600-A1 0x05010303 0x05010303
AST2600-A2 0x05010303 0x05020303
AST2620-A1 0x05010203 0x05010203
AST2620-A2 0x05010203 0x05020203
The SCU004 (silicon id 1) value matches SCU014 for A0, but for
subsequent revisions it is hard coded to the A1 value.
Qemu effectively dropped support for the A0 in 7582591ae7 ("aspeed:
Support AST2600A1 silicon revision") as the A0 reset table was removed,
so it makes sense to only support the behaviour of A1 and onwards.

Some machines don't have much differences a part from the flash model
being used. Introduce new machine properties to change them from the
command line.
For instance, to start the ast2500-evb machine with a different FMC
chip and a 64M SPI chip, use :
-M ast2500-evb,fmc-model=mx25l25635e,spi-model=mx66u51235f

The UART5 is present on the machine regardless there is a
character device connected to it. Map it unconditionally.

The cpu hotplug code handles the initialization of coldplugged cpus
too, so it is needed even in case cpu hotplug is not supported.
Wire cpu hotplug up for microvm.
Without this we get a broken MADT table.

Move the code from pc to x86, so microvm can use it.
Move both plug and unplug to keep everything in one place, even
though microvm needs plug only.
