On incoming migration we have the following sequence to load option
ROM:
1. On device realize we do normal load ROM from the file
2. Than, on incoming migration we rewrite ROM from the incoming RAM
block. If sizes mismatch we fail, like this:
Size mismatch: 0000:00:03.0/virtio-net-pci.rom: 0x40000 != 0x80000: Invalid argument
This is not ideal when we migrate to updated distribution: we have to
keep old ROM files in new distribution and be careful around romfile
property to load correct ROM file. Which is loaded actually just to
allocate the ROM with correct length.
Note, that romsize property doesn't really help: if we try to specify
it when default romfile is larger, it fails with something like:
romfile "efi-virtio.rom" (160768 bytes) is too large for ROM size 65536
Let's just ignore ROM file when romsize is specified and we are in
incoming migration state. In other words, we need only to preallocate
ROM of specified size, local ROM file is unrelated.
This way:
If romsize was specified on source, we just use same commandline as on
source, and migration will work independently of local ROM files on
target.
If romsize was not specified on source (and we have mismatching local
ROM file on target host), we have to specify romsize on target to match
source romsize. romfile parameter may be kept same as on source or may
be dropped, the file is not loaded anyway.
As a bonus we avoid extra reading from ROM file on target.
Note: when we don't have romsize parameter on source command line and
need it for target, it may be calculated as aligned up to power of two
size of ROM file on source (if we know, which file is it) or,
alternatively it may be retrieved from source QEMU by QMP qom-get
command, like
{ "execute": "qom-get",
"arguments": {
"path": "/machine/peripheral/CARD_ID/virtio-net-pci.rom[0]",
"property": "size" } }
Note: we have extra initialization of size variable to zero in
pci_add_option_rom to avoid false-positive
"error: ‘size’ may be used uninitialized"

These events include a copy of the device health information at the
time of the event. Actually using the emulated device health would
require a lot of controls to manipulate that state. Given the aim
of this injection code is to just test the flows when events occur,
inject the contents of the device health state as well.
Future work may add more sophisticate device health emulation
including direct generation of these records when events occur
(such as a temperature threshold being crossed). That does not
reduce the usefulness of this more basic generation of the events.

Analysis of the MacOS toolbox ROM code shows that on startup it attempts 2
separate reads of the seconds registers with commands 0x9d...0x91 followed by
0x8d..0x81 without resetting the command to its initial value. The PRAM seconds
value is only accepted when the values of the 2 separate reads match.
From this we conclude that bit 4 of the rtc command is not decoded or we don't
care about its value when reading the PRAM seconds registers. Implement this
decoding change so that both reads return successfully which allows the MacOS
toolbox ROM to correctly set the date/time.

The current use of aliased memory regions causes us 2 problems: firstly the
output of "info qom-tree" is absolutely huge and difficult to read, and
secondly we have already reached the internal limit for memory regions as
adding any new memory region into the mac-io region causes QEMU to assert
with "phys_section_add: Assertion `map->sections_nb < TARGET_PAGE_SIZE'
failed".
Implement the mac-io region aliasing using a single IO memory region that
applies IO_SLICE_MASK representing the maximum size of the aliased region and
then forwarding the access to the existing mac-io memory region using the
address space API.
