Like replay_linux.py, reverse_debugging.py starts the vm with console
set but does not interact with it (e.g., with wait_for_console_pattern).
In this situation, the console should have a drainer attached so the
socket does not fill. replay_linux.py has a drainer, but it is missing
from reverse_debugging.py.
Per analysis in Link: this can cause the console socket/pipe to fill and
QEMU get stuck in qemu_chr_write_buffer, leading to strange test case
failures (ppc64 fails because it prints a lot to console in early bios).
Attaching a drainer prevents this.
Note, this commit does not fix bugs introduced by the commits referenced
in the first two Fixes: tags, but together those commits conspire to
irritate the problem and cause test case failure, which this commit
fixes.

In a perfect world we'd have reproducible tests,
but then we'd be sure we run the same binaries.
If a binary artifact isn't hashed, we have no idea
what we are running. Therefore enforce hashing for
all our artifacts.
With this change, unhashed artifacts produce:

QEMU has validations to make sure that a VM is not started with more memory
(static and hotpluggable memory) than what the guest processor can address
directly with its addressing bits. This change adds a test to make sure QEMU
fails to start with a specific error message when an attempt is made to
start a VM with more memory than what the processor can directly address.
The test also checks for passing cases when the address space of the processor
is capable of addressing all memory. Boundary cases are tested.

Coverity complains about passing "&expected" to "run_range_inverse_array",
which dereferences null "expected". I guess the problem is that the
compare_ranges() loop dereferences 'e' without testing it. However the
loop condition is based on 'ranges' which is garanteed to have
the same length as 'expected' given the g_assert_cmpint() just
before the loop. So the code looks safe to me.
Nevertheless adding a test on expected before the loop to get rid of the
warning.

We requiere the 'ninja-build', which depends on 'python311':
$ pkgin show-deps ninja-build
direct dependencies for ninja-build-1.11.1nb1
python311>=3.11.0
So we end up installing both Python v3.10 and v3.11:
[31/76] installing python311-3.11.5...
[54/76] installing python310-3.10.13...
[74/76] installing py310-expat-3.10.13nb1...
Then the build system picks Python v3.11, and doesn't find
py-expat because we only installed the 3.10 version:
python determined to be '/usr/pkg/bin/python3.11'
python version: Python 3.11.5
*** Ouch! ***
Python's pyexpat module is not found.
It's normally part of the Python standard library, maybe your distribution packages it separately?
Either install pyexpat, or alleviate the need for it in the first place by installing pip and setuptools for '/usr/pkg/bin/python3.11'.
(Hint: NetBSD's pkgsrc debundles this to e.g. 'py310-expat'.)

bdrv_change_backing_file() is called both inside and outside coroutine
context. This makes it difficult for it to take the graph lock
internally. It also means that driver implementations need to be able to
run outside of coroutines, too. Switch it to the usual model with a
coroutine based implementation and a co_wrapper instead. The new
function is marked GRAPH_RDLOCK.
As the co_wrapper now runs the function in the AioContext of the node
(as it should always have done), this is not GLOBAL_STATE_CODE() any
more.

We already do a couple of "info registers" for specific tests but this
is a more comprehensive multiarch test. It also has some output
helpful for debugging the gdbstub by showing which XML features are
advertised and what the underlying register numbers are.
My initial motivation was to see if there are any duplicate register
names exposed via the gdbstub while I was reviewing the proposed
register interface for TCG plugins.
Mismatches between the xml and remote-desc are reported for debugging
but do not fail the test.
We also skip the tests for the following arches for now until we can
investigate and fix any issues:
- s390x (fails to read v0l->v15l, not seen in remote-registers)
- ppc64 (fails to read vs0h->vs31h, not seen in remote-registers)

Before commit "hw/ide: reset: cancel async DMA operation before
resetting state", this test would fail, because a reset with a
pending write operation would lead to an unsolicited write to the
first sector of the disk.
The test writes a pattern to the beginning of the disk and verifies
that it is still intact after a reset with a pending operation. It
also checks that the pending operation actually completes correctly.

Console logs from the VM can be useful for debugging when things go wrong.
Other avocado tests enables them. This change enables console logging with the
following changes:
- point to the newer bios bits image that actually enabled VM console.
- change the bits test to drain the console logs from the VM and write the
logs.
- wait for SHUTDOWN event from QEMU so that console logs can be drained out
of the socket before it is closed as a part of vm.wait().
Additionally, following two cosmetic changes have been made:
- Removed VM QEMU command line logging as avocado framework already logs it.
This is a minor cleanup along the way.
- Update my email to my work email in the avocado acpi bios bits test.

QEMU defaults to 64-bit entry point since the following commit
bf376f3020 ("hw/i386/pc: Default to use SMBIOS 3.0 for newer machine models")
The above change is applicable for all newer machine versions from version 8.1
and newer. i440fx and q35 machine versions 8.0 and older still use 32-bit entry
points.
Unfortunately, bits currently does not recognize 64-bit entry points and hence
is not able to parse SMBIOS tables. Therefore, we need to enforce 32-bit
SMBIOS entry point in QEMU command line so that bits is able to parse the
SMBIOS tables.
Once we implement the support in bits to parse 64-bit entry points, we can
remove the extra command line that is passed to enforce a 32-bit entry point.
The support can be added to the following smbios test script:
tests/avocado/acpi-bits/bits-tests/smbios.py2 in QEMU repository.

This tests the commit 7298fd7de5 ("hw/smbios: Fix thread count in
type4").
In smbios_build_type_4_table() (hw/smbios/smbios.c), if the number of
threads in the socket is more than 255, then smbios type4 table encodes
threads per socket into the thread count2 field.
So for the topology in this case, there're the following considerations:
1. threads per socket should be more than 255 to ensure we could cover
the thread count2 field.
2. The original bug was that threads per socket was miscalculated, so
now we should configure as many topology levels as possible (multiple
dies, no module since x86 hasn't supported it) to cover more general
topology scenarios, to ensure that the threads per socket encoded in
the thread count2 field is correct.
3. For the more general topology, we should also add "cpus" (presented
threads for machine) and "maxcpus" (total threads for machine) to
make sure that configuring unpluged CPUs in smp (cpus < maxcpus)
does not affect the correctness of threads per socket for thread
count2 field.
Note we don't consider the topology with multiple sockets since this
topology would create too many vCPUs (more than 255 threads per socket
with at least 2 sockets, which may cause the failure "Number of
hotpluggable cpus requested (*) exceeds the maximum cpus supported by
KVM (*) socket_accept failed: Resource temporarily unavailable"), and
the calculation of threads per socket has already been covered by
"thread count" test case.
Based on these considerations, select the topology as the follow:
-smp cpus=210,maxcpus=260,dies=2,cores=65,threads=2
The expected thread count2 = threads per socket = threads (2)
* cores (65) * dies (2) = 260.
