The original implementation of the Macintosh VIA devices in commit 6dca62a000
"hw/m68k: add VIA support" used timer optimisations to reduce high CPU usage on
the host when booting Linux. These optimisations worked by waiting until VIA1
port B was accessed before re-arming the timers.
The MacOS toolbox ROM constantly writes to VIA1 port B which calls
via1_one_second_update() and via1_sixty_hz_update() to calculate the new expiry
time, causing the timers to constantly reset and never fire. The effect of this
is that the Ticks (0x16a) global variable holding the number of 60Hz timer ticks
since reset is never incremented by the interrupt causing time to stand still.
Whilst the code was introduced as a performance optimisation, it is likely that
the high CPU usage was actually caused by the incorrect 60Hz timer interval
fixed in the previous patch. Remove the optimisation to keep everything simple
and enable the MacOS toolbox ROM to start keeping time.

The current workaround for the Linux ADB state machine in kernels < 5.6 switching
the VIA back to IDLE state between send and receive modes is to re-inject the
first byte of the response in the IDLE state, and then force the state machine
into generating an autopoll reply.
In fact what is happening is much simpler: analysis of traces from a real Quadra
suggest that the existing data is returned as the first autopoll response rather
than generating an immediate response starting whilst still in IDLE state.
Update the ADB receive code to work in the same way, which allows the re-injection
code to be completely removed from adb_via_receive() and for adb_via_poll() to
be simplified accordingly.

For the sparse-mem device, we want the fuzzer to populate entire DMA
reads from sparse-mem, rather than hooking into the individual MMIO
memory_region_dispatch_read operations. Otherwise, the fuzzer will treat
each sequential read separately (and populate it with a separate
pattern). Work around this by rearranging some DMA hooks. Since the
fuzzer has it's own logic to skip accidentally writing to MMIO regions,

For testing, it can be useful to simulate an enormous amount of memory

When something writes a nonzero value to a sparse-mem address, we
allocate a block of memory. For now, since the only user of this device
is the fuzzer, we do not track and free zeroed blocks. The device has a
very low priority (so it can be mapped beneath actual RAM, and virtual
device MMIO regions).

For now the switch of vfio dirty page tracking is integrated into
@vfio_save_handler. The reason is that some PCI vendor driver may
start to track dirty base on _SAVING state of device, so if dirty
tracking is started before setting device state, vfio will report
full-dirty to QEMU.
However, the dirty bmap of all ramblocks are fully set when setup
ram saving, so it's not matter whether the device is in _SAVING
state when start vfio dirty tracking.
Moreover, this logic causes some problems [1]. The object of dirty
tracking is guest memory, but the object of @vfio_save_handler is
device state, which produces unnecessary coupling and conflicts:
1. Coupling: Their saving granule is different (perVM vs perDevice).
vfio will enable dirty_page_tracking for each devices, actually
once is enough.
2. Conflicts: The ram_save_setup() traverses all memory_listeners
to execute their log_start() and log_sync() hooks to get the
first round dirty bitmap, which is used by the bulk stage of
ram saving. However, as vfio dirty tracking is not yet started,
it can't get dirty bitmap from vfio. Then we give up the chance
to handle vfio dirty page at bulk stage.
Move the switch of vfio dirty_page_tracking into vfio_memory_listener
can solve above problems. Besides, Do not require devices in SAVING
state for vfio_sync_dirty_bitmap().

[aw: The Fixes commit below introduced code to restrict migration
support to configurations where the target page size intersects the

Due to the above flexibility in bitmap handling, this restriction
unnecessarily prevents mixed target/host pages size that could
