Looks good. Can you just add a "# Submodules" heading above the test?
I would also like to remove the "yes" value (that is, the default fails if

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-mo
Turn on the spe cpu property by default if host cpu
support it, i.e. we can now do '-cpu max|host' to add
the vSPE, and '-cpu max|host,spe=off' to remove it.

Kernel commit 492855939bdb added a limit to the number of outstanding DMA

When an s390 guest is using lazy unmapping, it can result in a very
large number of oustanding DMA requests, far beyond the default
limit configured for vfio. Let's track DMA usage similar to vfio
in the host, and trigger the guest to flush their DMA mappings
before vfio runs out.

The Xilinx ZynqMP CAN controller is developed based on SocketCAN, QEMU CAN bus
implementation. Bus connection and socketCAN connection for each CAN module
can be set through command lines.
Example for using single CAN:
-object can-bus,id=canbus0 \
-machine xlnx-zcu102.canbus0=canbus0 \
Connect CAN0 and CAN1 on the ZynqMP.

PS, this can never be true:
+ (vdev->device_id & 0xff00) == 0x1425))
The lower byte would always be 00. It's the wrong fix anyway, BAR4 is
still missing.

Commit 19ae9ae014 ("block/rbd: Add support for ceph namespaces")

The 'namespace' is used to identify the image, so it is a strong
option since it can changes the data of a BDS.
