cd093d5a2c avocado_qemu: add exec_command function
Sometimes a test needs to send a command to a console without waiting
for a pattern as a result, or the command issued do not produce any kind
of output, like, for example, a `mount` command.

This introduces the `exec_command` function to the avocado_qemu,
allowing the test to send a command to the console without the need to
match a pattern produced as a result.

f9cc00346d tests/migration: fix unix socket batch migration
when execute the following test command:
"guestperf-batch.py --dst-host localhost --transport unix ..."
test aborts and error message as the following be throwed:
"launching VM Failed: [Errno 98] Address already in use".

The reason is that batch script use the same monitor socket
in all test cases and do not remove the socket file. The second
migration test will launch vm use the same socket file as
the first, so we get the error message. To fix it, just remove
the socket file each time we have done the migration test.

30ca7eddc4 mac_via: remove VIA1 timer optimisations
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.

According to the "Guide To The Macintosh Family Hardware", the 60Hz VIA1 timer
on newer Macs such as the Quadra only exists for compatibility with old software

Rename the VBL timer to 60Hz timer to emphasise this and to prevent confusion

a67ffaf0ec mac_via: don't re-inject ADB response when switching to IDLE state
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.

7cac7fea70 fuzz: move some DMA hooks
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,
we can call the DMA cb, outside the flatview_translate loop.

25d309fb0d fuzz: configure a sparse-mem device, by default
The generic-fuzzer often provides randomized DMA addresses to
virtual-devices. For a 64-bit address-space, the chance of these
randomized addresses coinciding with RAM regions, is fairly small. Even
though the fuzzer's instrumentation eventually finds valid addresses,
this can take some-time, and slows-down fuzzing progress (especially,
when multiple DMA buffers are involved). To work around this, create
"fake" sparse-memory that spans all of the 64-bit address-space. Adjust
the DMA call-back to populate this sparse memory, correspondingly

230376d285 memory: add a sparse memory device for fuzzing
For testing, it can be useful to simulate an enormous amount of memory
(e.g. 2^64 RAM). This adds an MMIO device that acts as sparse 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).

I noticed that with a sufficiently small timeout, the fuzzer fork-server

caused by entering our SIGALRM handler, while libfuzzer is in it's crash

external child process to print out stack-traces, we shouldn't exit
early, and leave an orphan child. Check for children in the SIGALRM

758b96b61d vfio/migrate: Move switch of dirty tracking into vfio_memory_listener
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().

1eb7f64275 vfio: Support host translation granule size
The cpu_physical_memory_set_dirty_lebitmap() can quickly deal with
the dirty pages of memory by bitmap-traveling, regardless of whether
the bitmap is aligned correctly or not.

cpu_physical_memory_set_dirty_lebitmap() supports pages in bitmap of
host page size. So it'd better to set bitmap_pgsize to host page size
to support more translation granule sizes.

[aw: The Fixes commit below introduced code to restrict migration
support to configurations where the target page size intersects the
host dirty page support.  For example, a 4K guest on a 4K host.
Due to the above flexibility in bitmap handling, this restriction
unnecessarily prevents mixed target/host pages size that could
otherwise be supported.  Use host page size for dirty bitmap.]
