When running 'info network', if the stream backend is still in
the process of connecting, or waiting for an incoming connection,
no information is displayed.
There is also no way to distinguish whether the server is still
in the process of setting up the listener socket, or whether it
is ready to accept incoming client connections.
This leads to a race condition in the netdev-socket qtest which
launches a server process followed by a client process. Under
high load conditions it is possible for the client to attempt
to connect before the server is accepting clients. For the
scenarios which do not set the 'reconnect' option, this opens
up a race which can lead to the test scenario failing to reach
the expected state.
Now that 'info network' can distinguish between initialization
phase and the listening phase, the netdev-socket qtest will
correctly synchronize, such that the client QEMU is not spawned
until the server is ready.
This should solve the non-deterministic failures seen with the
netdev-socket qtest.

ALU instructions can write to both memory and flags. If the CC_SRC*
and CC_DST locations have been written already when a memory access
causes a fault, the value in CC_SRC* and CC_DST might be interpreted
with the wrong CC_OP (the one that is in effect before the instruction.
Besides just using the wrong result for the flags, something like
subtracting -1 can have disastrous effects if the current CC_OP is
CC_OP_EFLAGS: this is because QEMU does not expect bits outside the ALU
flags to be set in CC_SRC, and env->eflags can end up set to all-ones.
In the case of the attached testcase, this sets IOPL to 3 and would
cause an assertion failure if SUB is moved to the new decoder.
This mechanism is not really needed for BMI instructions, which can
only write to a register, but put it to use anyway for cleanliness.
In the case of BZHI, the code has to be modified slightly to ensure
that decode->cc_src is written, otherwise the new assertions trigger.

I am not sure whether deadlocks are still possible. Maybe they have just

unchanged and just removed mention of the AioContext.

The test functions set expected data and clear the flag before calling

Make test_qapi_event_emit() consume expected data, and the test

When dumping table blobs using rebuild-expected-aml.sh, table blobs from all
test variants are dumped regardless of whether there are any actual changes to
the tables or not. This creates lot of new files for various test variants that
are not part of the git repository. This is because we do not check in all table
blobs for all test variants into the repository. Only those blobs for those
variants that are different from the generic test-variant agnostic blob are
checked in.
This change makes the test smarter by checking if at all there are any changes
in the tables from the checked-in gold master blobs and take actions
accordingly.
When there are no changes:
- No new table blobs would be written.
- Existing table blobs will be refreshed (git diff will show no changes).
When there are changes:
- New table blob files will be dumped.
- Existing table blobs will be refreshed (git diff will show that the files
changed, asl diff will show the actual changes).
When new tables are introduced:
- Zero byte empty file blobs for new tables as instructed in the header of
bios-tables-test.c will be regenerated to actual table blobs.
This would make analyzing changes to tables less confusing and there would
be no need to clean useless untracked files when there are no table changes.

It doesn't make sense to have two classes of flaky tests. While it may
take the constrained environment of CI to trigger failures easily it
doesn't mean they don't occasionally happen on developer machines. As
CI is the gating factor to passing there is no point developers
running the tests locally anyway unless they are trying to fix things.
While we are at it update the language in the docs to discourage the
QEMU_TEST_FLAKY_TESTS becoming a permanent solution.

In commit edac4d8a16 back in 2015 when we added support for
the virtual timer offset CNTVOFF_EL2, we didn't correctly update
the timer-recalculation code that figures out when the timer
interrupt is next going to change state. We got it wrong in
two ways:
* for the 0->1 transition, we didn't notice that gt->cval + offset
can overflow a uint64_t
* for the 1->0 transition, we didn't notice that the transition
might now happen before the count rolls over, if offset > count
In the former case, we end up trying to set the next interrupt
for a time in the past, which results in QEMU hanging as the
timer fires continuously.
In the latter case, we would fail to update the interrupt
status when we are supposed to.
Fix the calculations in both cases.
The test case is Alex Bennée's from the bug report, and tests
the 0->1 transition overflow case.

The reason the ppc64 and s390x test where failing was because gdb
hides them although they are still accessible via regnum. We can
re-arrange the test a little bit and include these two arches in our
test.
We also need to be a bit more careful handling remote-registers as the
format isn't easily parsed with pure white space separation. Once we
fold types like "long long" and "long double" into a single word we
can now assert all registers are either listed or elided.

This tests two parallel stream jobs that will complete around the same
time and run on two different disks in the same iothreads. It is loosely
based on the bug report at https://issues.redhat.com/browse/RHEL-1761.
For me, this test hangs reliably with the originally reported bug in
blk_remove_bs(). After fixing it, it intermittently hangs for the bugs
fixed after it, missing AioContext unlocking in bdrv_graph_wrunlock()
and in stream_prepare(). The deadlocks seem to happen more frequently
when the test directory is on tmpfs.

bdrv_graph_wrunlock() calls aio_poll(), which may run callbacks that
have a nested event loop. Nested event loops can depend on other
iothreads making progress, so in order to allow them to make progress it
must not hold the AioContext lock of another thread while calling
aio_poll().
This introduces a @bs parameter to bdrv_graph_wrunlock() whose
AioContext is temporarily dropped (which matches bdrv_graph_wrlock()),
and a bdrv_graph_wrunlock_ctx() that can be used if the BlockDriverState
doesn't necessarily exist any more when unlocking.
This also requires a change to bdrv_schedule_unref(), which was relying
on the incorrectly taken lock. It needs to take the lock itself now.
While this is a separate bug, it can't be fixed a separate patch because
otherwise the intermediate state would either deadlock or try to release
a lock that we don't even hold.

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

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'.)
ERROR: python venv creation failed
Fix by installing py-expat for v3.11. Remove the v3.10
packages since we aren't using them anymore.

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.

nios2 signal tests are broken again:

Ran command 10 times, 8 passes
This wasn't picked up by CI as we don't have a docker container that
can build QEMU with the nios2 compiler. I don't have time to bisect
the breakage and the target is orphaned anyway so take the easy route
and revert it.

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)

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.

The commit 196ea60a73 ("hw/smbios: Fix core count in type4") fixed
the miscalculation of cores per socket.
The original core count2 test (with the topology configured by
"-smp 275") didn't recognize that topology-related but because it just
created a special topology with only one socket and one die by default,
ignoring the effect of more topology levels (between socket and core) on
the cores per socket calculation.
So for the topology in this case, there're the following considerations:
1. cores per socket should be more than 255 to ensure we could cover
the core count2 field.
2. The original bug was that cores per socket was miscalculated, so now
we should include as many topology levels as possible (multiple
sockets or dies, no module since x86 hasn't supported it) to cover
more general topology scenarios, to ensure that the cores per socket
encoded in the core count2 field is correct.
Based on these considerations, select the topology with multiple dies:
-smp 260,dies=2,cores=130,threads=1
Note, here we doesn't configure multiple sockets to avoid the error
("kvm_init_vcpu: kvm_get_vcpu failed (*): Too many open files") if user
uses the default ulimit seeting on his machine.
And the cores per socket calculation for multiple sockets has already
been covered by the core count test case, so that only multiple dies
configuration is enough.
The expected core count2 = cores per socket = cores (130) * dies (2) =
260.

to exclude the effect of other topology levels to create the type4
tables only for sockets.
3. The original miscalculation bug also misused "smp.cpus", so it's
necessary to configure "cpus" (presented threads for machine) and
"maxcpus" (total threads for machine) as well to make sure that
configuring unpluged CPUs in smp (cpus < maxcpus) does not affect
the correctness of the count of type4 tables.
Based on these considerations, select the topology as the follow:
-smp cpus=100,maxcpus=120,sockets=5,dies=2,cores=4,threads=3
The expected count of type4 tables = sockets (5).

Migration dirty-limit capability introduce dirty limit
capability, two parameters: x-vcpu-dirty-limit-period and
vcpu-dirty-limit are introduced to implement the live
migration with dirty limit.
The test case does the following things:
1. start src, dst vm and enable dirty-limit capability
2. start migrate and set cancel it to check if dirty limit
stop working.
3. restart dst vm
4. start migrate and enable dirty-limit capability
5. check if migration satisfy the convergence condition

The qdev conversion in this pull request ("stellaris-gamepad: Convert
to qdev") eliminates the vmstate_register() call that was converted to
vmstate_register_any() in the conflicting migration pull request.
vmstate_register_any() is no longer necessary now that this device has
been converted to qdev, so take this pull request's version of
stellaris_gamepad.c over the previous pull request's
stellaris_input.c (the file was renamed).

Feed those fake sockets to src/dst QEMUs for recovery to let them go into
RECOVER stage without going out. Test that we can always kick it out and

One part of the test is using a throttled source to ensure that there
are no obvious issues when changing the copy_mode while there are
ongoing requests (source and target images are compared at the very
end).
The other part of the test is using a throttled target to ensure that
the change to active mode actually happened. This is done by hitting
the throttling limit, issuing a synchronous write and then immediately
verifying the target side. QSD is used, because otherwise, a
synchronous write would hang there.

To start out, only actively-synced is returned.
For example, this is useful for jobs that started out in background
mode and switched to active mode. Once actively-synced is true, it's
clear that the mode switch has been completed. Note that completion of
the switch might happen much earlier, e.g. if the switch happens
before the job is ready, once all background operations have finished.
It's assumed that whether the disks are actively-synced or not is more
interesting than whether the mode switch completed. That information
can still be added if required in the future.
In presence of an iothread, the actively_synced member is now shared
between the iothread and the main thread, so turn accesses to it
atomic.
Requires to adapt the output for iotest 109.

1. Check that compression mode isn't compatible with "-f raw" (raw
format doesn't support compression).
2. Check that rebasing an image onto no backing file preserves the data
and writes the copied clusters actually compressed.
3. Same as 2, but with a raw backing file (i.e. the clusters copied from the

after being merged).
4. Remove a single delta from a backing chain, perform the same checks
as in 2.
5. Check that even when backing and overlay are initially uncompressed,
copied clusters end up compressed when rebase with compression is
performed.
271:
1. Check that when target image has subclusters, rebase with compression
will make an entire cluster containing the written subcluster
compressed.

As the previous commit changes the logic of "qemu-img rebase" (it's using
write alignment now), let's add a couple more test cases which would
ensure it works correctly. In particular, the following scenarios:
024: add test case for rebase within one backing chain when the overlay
cluster size > backings cluster size;
271: add test case for rebase images that contain subclusters. Check
that no extra allocations are being made.

Before previous commit, rebase was getting infitely stuck in case of
rebasing within the same backing chain and when overlay_size > backing_size.
Let's add this case to the rebasing test 024 to make sure it doesn't
break again.

This patch removes the code that ufs-lu was duplicating from
scsi-hd and allows them to share code.
It makes ufs-lu have a virtual scsi-bus and scsi-hd internally.
This allows scsi related commands to be passed thorugh to the scsi-hd.
The query request and nop command work the same as the existing logic.
Well-known lus do not have a virtual scsi-bus and scsi-hd, and
handle the necessary scsi commands by emulating them directly.

Accept the QTEST_QEMU_MACHINE_TYPE environment variable to take a
machine type to use in the tests.
The full machine type is recognized (e.g. pc-q35-8.2). Aliases
(e.g. pc) are also allowed and resolve to the latest machine version
for that alias, or, if using two QEMU binaries, to the latest common

We have strict rules around migration compatibility between different
QEMU versions but no test to validate the migration state between
different binaries.
Add infrastructure to allow running the migration tests with two
different QEMU binaries as migration source and destination.
The code now recognizes two new environment variables
QTEST_QEMU_BINARY_SRC and QTEST_QEMU_BINARY_DST. In the absence of
either of them, the test will use the QTEST_QEMU_BINARY variable. If
both are missing then the tests are run with single binary as
previously.
The machine type is selected automatically as the latest machine type
version that works with both binaries.
Usage (only one of SRC|DST is allowed):
QTEST_QEMU_BINARY_SRC=../build-8.2.0/qemu-system-x86_64 \
QTEST_QEMU_BINARY=../build-8.1.0/qemu-system-x86_64 \

We're about to enable the x86_64 tests to run with the q35 machine,
but that machine does not work with the program we use to dirty the
memory for the tests.
The issue is that QEMU needs to guess the geometry of the "disk" we
give to it and the guessed geometry doesn't pass the sanity checks
done by SeaBIOS. This causes SeaBIOS to interpret the geometry as if
needing a translation from LBA to CHS and SeaBIOS ends up miscomputing
the number of cylinders and aborting due to that.
The reason things work with the "pc" machine is that is uses ATA
instead of AHCI like q35 and SeaBIOS has an exception for ATA that
ends up skipping the sanity checks and ignoring translation
altogether.
Workaround this situation by specifying a geometry in the command
line.

The migration tests are being enhanced to test migration between
different QEMU versions. A requirement of migration is that the
machine type between source and destination matches, including the
version.
We cannot hardcode machine types in the tests because those change
with each release. QEMU provides a machine type alias that has a fixed
name, but points to the latest machine type at each release.
Add a helper to resolve the alias into the exact machine
type. E.g. "-machine pc" resolves to "pc-i440fx-8.2"

Draining recursively traverses the graph, therefore we need to make sure
that also such accesses to the graph are protected by the graph rdlock.
There are 3 different drain callers to consider:
1. drain in the main loop: no issue at all, rdlock is nop.
2. drain in an iothread: rdlock only works in main loop or coroutines,
so disallow it.
3. drain in a coroutine (regardless of AioContext): the drain mechanism
takes care of scheduling a BH in the bs->aio_context that will
then take care of perform the actual draining. This is wrong,
because as pointed in (2) if bs->aio_context is an iothread then
rdlock won't work. Therefore change bdrv_co_yield_to_drain to
schedule the BH in the main loop.
Caller (2) also implies that we need to modify test-bdrv-drain.c to
disallow draining in the iothreads.
For some places, we know that they will hold the lock, but we don't have
the GRAPH_RDLOCK annotations yet. In this case, add assume_graph_lock()
with a FIXME comment. These places will be removed once everything is
properly annotated.

AIO callbacks are effectively coroutine_mixed_fn. If AIO requests don't
return immediately, their callback is called from the request coroutine.
This means that in AIO callbacks, we can't call no_coroutine_fns such as
bdrv_graph_wrlock(). Unfortunately test-bdrv-drain does so.
Change the test to use a BH to drop out of coroutine context, and add
coroutine_mixed_fn and no_coroutine_fn markers to clarify the context
each function runs in.

its extensions, we don't need the sock_dir argument anymore, so remove
it.
We only added this argument so that we could specify a second, shorter

a socket name on macOS. We don't need it for this class now. In one
case, avocado testing takes over responsibility for creating an

file-based migration requires the target to initiate its migration after
the source has finished writing out the data in the file. Currently
there's no easy way to initiate 'migrate-incoming', allow this by
introducing migrate_incoming_qmp helper, similarly to migrate_qmp.
Also make sure migration events are enabled and wait for the incoming
migration to start before returning. This avoid a race when querying
the migration status too soon after issuing the command.

Since 0b1a649047 (tests/docker: use direct RUNC call to build
containers) we ended up with the potential for the remaining docker.py
script calls to deviate from the direct RUNC calls. Fix this by
dropping the use of ENGINE in the makefile and rely entirely on what
we detect at configure time.
We also tweak the RUNC detection so podman users can still run things

Allow a client to request a subset of negotiated meta contexts. For
example, a client may ask to use a single connection to learn about
both block status and dirty bitmaps, but where the dirty bitmap
queries only need to be performed on a subset of the disk; forcing the
server to compute that information on block status queries in the rest
of the disk is wasted effort (both at the server, and on the amount of
traffic sent over the wire to be parsed and ignored by the client).
Qemu as an NBD client never requests to use more than one meta
context, so it has no need to use block status payloads. Testing this
instead requires support from libnbd, which CAN access multiple meta
contexts in parallel from a single NBD connection; an interop test
submitted to the libnbd project at the same time as this patch
demonstrates the feature working, as well as testing some corner cases
(for example, when the payload length is longer than the export
length), although other corner cases (like passing the same id
duplicated) requires a protocol fuzzer because libnbd is not wired up
to break the protocol that badly.
This also includes tweaks to 'qemu-nbd --list' to show when a server
is advertising the capability, and to the testsuite to reflect the
addition to that output.
Of note: qemu will always advertise the new feature bit during
NBD_OPT_INFO if extended headers have alreay been negotiated
(regardless of whether any NBD_OPT_SET_META_CONTEXT negotiation has
occurred); but for NBD_OPT_GO, qemu only advertises the feature if
block status is also enabled (that is, if the client does not
negotiate any contexts, then NBD_CMD_BLOCK_STATUS cannot be used, so
the feature is not advertised).

[eblake: fix logic to reject unnegotiated contexts]
Signed-off-by: Eric Blake <eblake@redhat.com>
All the pieces are in place for a client to finally request extended
headers. Note that we must not request extended headers when qemu-nbd
is used to connect to the kernel module (as nbd.ko does not expect
them, but expects us to do the negotiation in userspace before handing
the socket over to the kernel), but there is no harm in all other
clients requesting them.
Extended headers are not essential to the information collected during
'qemu-nbd --list', but probing for it gives us one more piece of
information in that output. Update the iotests affected by the new
line of output.

32-bit x86 systems do not have a reserved memory for hole64. On those 32-bit
systems without PSE36 or PAE CPU features, hotplugging memory devices are not
supported by QEMU as QEMU always places hotplugged memory above 4 GiB boundary
which is beyond the physical address space of the processor. Linux guests also
does not support memory hotplug on those systems. Please see Linux
kernel commit b59d02ed08690 ("mm/memory_hotplug: disable the functionality
for 32b") for more details.
Therefore, the maximum limit of the guest physical address in the absence of
additional memory devices effectively coincides with the end of
"above 4G memory space" region for 32-bit x86 without PAE/PSE36. When users
configure additional memory devices, after properly accounting for the
additional device memory region to find the maximum value of the guest
physical address, the address will be outside the range of the processor's
physical address space.
This change adds improvements to take above into consideration.
For example, previously this was allowed:
$ ./qemu-system-x86_64 -cpu pentium -m size=10G
With this change now it is no longer allowed:
$ ./qemu-system-x86_64 -cpu pentium -m size=10G
qemu-system-x86_64: Address space limit 0xffffffff < 0x2bfffffff phys-bits too low (32)
However, the following are allowed since on both cases physical address
space of the processor is 36 bits:
$ ./qemu-system-x86_64 -cpu pentium2 -m size=10G
$ ./qemu-system-x86_64 -cpu pentium,pse36=on -m size=10G
For 32-bit, without PAE/PSE36, hotplugging additional memory is no longer allowed.
$ ./qemu-system-i386 -m size=1G,maxmem=3G,slots=2
qemu-system-i386: Address space limit 0xffffffff < 0x1ffffffff phys-bits too low (32)
$ ./qemu-system-i386 -machine q35 -m size=1G,maxmem=3G,slots=2
qemu-system-i386: Address space limit 0xffffffff < 0x1ffffffff phys-bits too low (32)
A new compatibility flag is introduced to make sure pc_max_used_gpa() keeps
returning the old value for machines 8.1 and older.
Therefore, the above is still allowed for older machine types in order to support
compatibility. Hence, the following still works:
$ ./qemu-system-i386 -machine pc-i440fx-8.1 -m size=1G,maxmem=3G,slots=2
$ ./qemu-system-i386 -machine pc-q35-8.1 -m size=1G,maxmem=3G,slots=2
Further, following is also allowed as with PSE36, the processor has 36-bit
address space:
$ ./qemu-system-i386 -cpu 486,pse36=on -m size=1G,maxmem=3G,slots=2
After calling CPUID with EAX=0x80000001, all AMD64 compliant processors
have the longmode-capable-bit turned on in the extended feature flags (bit 29)
in EDX. The absence of CPUID longmode can be used to differentiate between
32-bit and 64-bit processors and is the recommended approach. QEMU takes this
approach elsewhere (for example, please see x86_cpu_realizefn()), With
this change, pc_max_used_gpa() also uses the same method to detect 32-bit
processors.
Unit tests are modified to not run 32-bit x86 tests that use memory hotplug.

The migration qtest all the way up to this point used to work by sheer
luck relying on the contents of all pages from 1MiB to 100MiB to contain
the same one value in the first byte initially.
This easily breaks if we reduce the amount of RAM for the test instances
from 150MiB to e.g 110MiB since that makes SeaBIOS dirty some of the
pages starting at about 0x5dd2000 (~93 MiB) as it reuses those for the
HighMemory allocator since commit dc88f9b72df ("malloc: use large
ZoneHigh when there is enough memory").
This would result in the following errors:

Originally meant to avoid a shadowed variable "s", which was fixed by
renaming the outer declaration to "qts". Avoid the chance of an overflow
in the computation of ABS(t - s).

These are the last users of the 128K SeaBIOS blob in the i440FX family.
Removing them allows us to drop PCI support from the 128K blob,
thus making it easier to update SeaBIOS to newer versions.

We need to check that we are able to create large enough file which is
used as an export base rather than connection URL. Unfortunately, there
are cases when the TEST_IMG_FILE is not defined. We should fallback to
TEST_IMG in that case.
This problem has been detected when running
./check -nbd 5
The test should be able to run while it does not.

For user-only mode we reveal a subset of the AArch64 ID registers
to the guest, to emulate the kernel's trap-and-emulate-ID-regs
handling. Update the feature bit masks to match upstream kernel
commit a48fa7efaf1161c1c.
None of these features are yet implemented by QEMU, so this
doesn't yet have a behavioural change, but implementation of
FEAT_MOPS and FEAT_HBC is imminent.

This patch fixes a race condition in test-bdrv-drain that is difficult
to reproduce. test-bdrv-drain sometimes fails without an error message
on the block pull request sent by Kevin Wolf on Sep 4, 2023. I was able
to reproduce it locally and found that "block-backend: process I/O in
the current AioContext" (in this patch series) is the first commit where
it reproduces.
I do not know why "block-backend: process I/O in the current AioContext"
exposes this bug. It might be related to the fact that the test's preadv
request runs in the main thread instead of IOThread a after my commit.
That might simply change the timing of the test.
Now on to the race condition in test-bdrv-drain. The main thread
schedules a BH in IOThread a and then drains the BDS:
aio_bh_schedule_oneshot(ctx_a, test_iothread_main_thread_bh, &data);
/* The request is running on the IOThread a. Draining its block device
* will make sure that it has completed as far as the BDS is concerned,
* but the drain in this thread can continue immediately after
* bdrv_dec_in_flight() and aio_ret might be assigned only slightly
* later. */
do_drain_begin(drain_type, bs);
If the BH completes before do_drain_begin() then there is nothing to
worry about.
If the BH invokes bdrv_flush() before do_drain_begin(), then
do_drain_begin() waits for it to complete.
The problematic case is when do_drain_begin() runs before the BH enters
bdrv_flush(). Then do_drain_begin() misses the BH and the drain
mechanism has failed in quiescing I/O.
Fix this by incrementing the in_flight counter so that do_drain_begin()
waits for test_iothread_main_thread_bh().

bdrv_unref() is called by a lot of places that need to hold the graph
lock (it naturally happens in the context of operations that change the
graph). However, bdrv_unref() takes the graph writer lock internally, so
it can't actually be called while already holding a graph lock without
causing a deadlock.
bdrv_unref() also can't just become GRAPH_WRLOCK because it drains the
node before closing it, and draining requires that the graph is
unlocked.
The solution is to defer deleting the node until we don't hold the lock
any more and draining is possible again.
Note that keeping images open for longer than necessary can create
problems, too: You can't open an image again before it is really closed
(if image locking didn't prevent it, it would cause corruption).
Reopening an image immediately happens at least during bdrv_open() and
bdrv_co_create().
In order to solve this problem, make sure to run the deferred unref in
bdrv_graph_wrunlock(), i.e. the first possible place where we can drain
again. This is also why bdrv_schedule_unref() is marked GRAPH_WRLOCK.
The output of iotest 051 is updated because the additional polling
changes the order of HMP output, resulting in a new "(qemu)" prompt in
the test output that was previously on a separate line and filtered out.

Occasionally some avocado tests will fail waiting for console line
despite the machine running correctly. Console data goes missing, as can
be seen in the console log. This is due to _console_interaction calling
makefile() on the console socket each time it is invoked, which must be
losing old buffer contents when going out of scope.
It is not enough to makefile() with buffered=0. That helps significantly
but data loss is still possible. My guess is that readline() has a line
buffer even when the file is in unbuffered mode, that can eat data.
Fix this by providing a console file that persists for the life of the
console.

AF_XDP is a network socket family that allows communication directly
with the network device driver in the kernel, bypassing most or all
of the kernel networking stack. In the essence, the technology is
pretty similar to netmap. But, unlike netmap, AF_XDP is Linux-native
and works with any network interfaces without driver modifications.
Unlike vhost-based backends (kernel, user, vdpa), AF_XDP doesn't
require access to character devices or unix sockets. Only access to
the network interface itself is necessary.
This patch implements a network backend that communicates with the
kernel by creating an AF_XDP socket. A chunk of userspace memory
is shared between QEMU and the host kernel. 4 ring buffers (Tx, Rx,
Fill and Completion) are placed in that memory along with a pool of
memory buffers for the packet data. Data transmission is done by
allocating one of the buffers, copying packet data into it and
placing the pointer into Tx ring. After transmission, device will
return the buffer via Completion ring. On Rx, device will take
a buffer form a pre-populated Fill ring, write the packet data into
it and place the buffer into Rx ring.
AF_XDP network backend takes on the communication with the host
kernel and the network interface and forwards packets to/from the
peer device in QEMU.
Usage example:
-device virtio-net-pci,netdev=guest1,mac=00:16:35:AF:AA:5C
-netdev af-xdp,ifname=ens6f1np1,id=guest1,mode=native,queues=1
XDP program bridges the socket with a network interface. It can be
attached to the interface in 2 different modes:
1. skb - this mode should work for any interface and doesn't require
driver support. With a caveat of lower performance.
2. native - this does require support from the driver and allows to
bypass skb allocation in the kernel and potentially use
zero-copy while getting packets in/out userspace.
By default, QEMU will try to use native mode and fall back to skb.
Mode can be forced via 'mode' option. To force 'copy' even in native
mode, use 'force-copy=on' option. This might be useful if there is
some issue with the driver.
Option 'queues=N' allows to specify how many device queues should
be open. Note that all the queues that are not open are still
functional and can receive traffic, but it will not be delivered to
QEMU. So, the number of device queues should generally match the
QEMU configuration, unless the device is shared with something
else and the traffic re-direction to appropriate queues is correctly
configured on a device level (e.g. with ethtool -N).
'start-queue=M' option can be used to specify from which queue id
QEMU should start configuring 'N' queues. It might also be necessary
to use this option with certain NICs, e.g. MLX5 NICs. See the docs
for examples.
In a general case QEMU will need CAP_NET_ADMIN and CAP_SYS_ADMIN
or CAP_BPF capabilities in order to load default XSK/XDP programs to
the network interface and configure BPF maps. It is possible, however,
to run with no capabilities. For that to work, an external process
with enough capabilities will need to pre-load default XSK program,
create AF_XDP sockets and pass their file descriptors to QEMU process
on startup via 'sock-fds' option. Network backend will need to be
configured with 'inhibit=on' to avoid loading of the program.
QEMU will need 32 MB of locked memory (RLIMIT_MEMLOCK) per queue
or CAP_IPC_LOCK.
There are few performance challenges with the current network backends.
First is that they do not support IO threads. This means that data
path is handled by the main thread in QEMU and may slow down other
work or may be slowed down by some other work. This also means that
taking advantage of multi-queue is generally not possible today.
Another thing is that data path is going through the device emulation
code, which is not really optimized for performance. The fastest
"frontend" device is virtio-net. But it's not optimized for heavy
traffic either, because it expects such use-cases to be handled via
some implementation of vhost (user, kernel, vdpa). In practice, we
have virtio notifications and rcu lock/unlock on a per-packet basis
and not very efficient accesses to the guest memory. Communication
channels between backend and frontend devices do not allow passing
more than one packet at a time as well.
Some of these challenges can be avoided in the future by adding better
batching into device emulation or by implementing vhost-af-xdp variant.
There are also a few kernel limitations. AF_XDP sockets do not
support any kinds of checksum or segmentation offloading. Buffers
are limited to a page size (4K), i.e. MTU is limited. Multi-buffer
support implementation for AF_XDP is in progress, but not ready yet.
Also, transmission in all non-zero-copy modes is synchronous, i.e.
done in a syscall. That doesn't allow high packet rates on virtual
interfaces.
However, keeping in mind all of these challenges, current implementation
of the AF_XDP backend shows a decent performance while running on top
of a physical NIC with zero-copy support.
Test setup:
2 VMs running on 2 physical hosts connected via ConnectX6-Dx card.
Network backend is configured to open the NIC directly in native mode.
The driver supports zero-copy. NIC is configured to use 1 queue.
Inside a VM - iperf3 for basic TCP performance testing and dpdk-testpmd
for PPS testing.
iperf3 result:
TCP stream : 19.1 Gbps
dpdk-testpmd (single queue, single CPU core, 64 B packets) results:
Tx only : 3.4 Mpps
Rx only : 2.0 Mpps
L2 FWD Loopback : 1.5 Mpps
In skb mode the same setup shows much lower performance, similar to
the setup where pair of physical NICs is replaced with veth pair:
iperf3 result:
TCP stream : 9 Gbps
dpdk-testpmd (single queue, single CPU core, 64 B packets) results:
Tx only : 1.2 Mpps
Rx only : 1.0 Mpps
L2 FWD Loopback : 0.7 Mpps
Results in skb mode or over the veth are close to results of a tap
backend with vhost=on and disabled segmentation offloading bridged
with a NIC.

do_vm_stop() is not inside the drained section used by qemu_cleanup()
anymore. I.e., there is a second drained section now that ends before
the final one in qemu_cleanup() starts. Thus, job_pause() is called

so let's remove the empty functions to avoid wasting some few

The command always fails with "Error: Parameter 'xbzrle_cache_size'

passes anyway. Change the argument from 1 to 64k to make the test a

docs/multi-thread-compression.txt uses parameter names with
underscores instead of dashes. Wrong since day one.
docs/rdma.txt, tests/qemu-iotests/181, and tests/qtest/test-hmp.c are
wrong the same way since commit cbde7be900 (v6.0.0). Hard to see,
as test-hmp doesn't check whether the commands work, and iotest 181
appears to be unaffected.

In the previous commit e2f938265e ("tests/qemu-iotests/197: add
testcase for CoR with subclusters") we've introduced a new testcase for
copy-on-read with subclusters. Test 197 always forces qcow2 as the top
image, but allows backing image to be in any format. That last test
case didn't meet these requirements, so let's fix it by using more
generic "qemu-io -c map" command.

Stop applying config-host.mak to the sourcesets, since it does not

While the option still needs to be parsed in the configure script
(it's needed by tests/tcg, and also to decide about recursing
into contrib/plugins), passing it to Meson can be done with -D
instead of using config-host.mak.

The reverse-debugging test creates a trace, then replays it and:
1. Steps the first 10 instructions and records their addresses.
2. Steps backward and verifies their addresses match.
3. Runs to (near) the end of the trace.
4. Sets breakpoints on the first 10 instructions.
5. Continues backward and verifies execution stops at the last
breakpoint.
Step 5 breaks if any of the other 9 breakpoints are re-executed in the
trace after the 10th instruction is run, because those will be
unexpectedly hit when reverse continuing. This situation does arise
with the ppc pseries machine, the SLOF bios branches to its own entry
point.
Deal with this by switching steps 3 and 4, so the trace will be run to
the end *or* one of the breakpoints being re-executed. Step 5 then
reverses from there to the 10th instruction will not hit a breakpoint in
between, by definition.
Another step is added between steps 2 and 3, which steps forward over
the first 10 instructions and verifies their addresses, to support this.

Since commit 139c1837db ("meson: rename included C source files

use *.c.inc.
Besides, since commit 6a0057aa22 ("docs/devel: make a statement
about includes") this is documented as the Coding Style:
If you do use template header files they should be named with
the ``.c.inc`` or ``.h.inc`` suffix to make it clear they are
being included for expansion.
Therefore rename 'bti-crt.inc.c' as 'bti-crt.c.inc'.

We use a variable-length array in inet_get_free_port_multiple().
This is only test code called at the start of a test, so switch to a
heap allocation instead.
The codebase has very few VLAs, and if we can get rid of them all we
can make the compiler error on new additions. This is a defensive
measure against security bugs where an on-stack dynamic allocation
isn't correctly size-checked (e.g. CVE-2021-3527).

The `ccache` tool can be very effective at reducing compilation times
when re-running pipelines with only minor changes each time. For example
a fresh 'build-system-fedora' job will typically take 20 minutes on the
gitlab.com shared runners. With ccache this is reduced to as little as
6 minutes.
Normally meson would auto-detect existance of ccache in $PATH and use
it automatically, but the way we wrap meson from configure breaks this,
as we're passing in an config file with explicitly set compiler paths.
Thus we need to add $CCACHE_WRAPPERSPATH to the front of $PATH. For
unknown reasons if doing this in msys though, gcc becomes unable to
invoke 'cc1' when run from meson. For msys we thus set CC='ccache gcc'
before invoking 'configure' instead.
A second problem with msys is that cache misses are incredibly
expensive, so enabling ccache massively slows down the build when
the cache isn't well populated. This is suspected to be a result of
the cost of spawning processes under the msys architecture. To deal
with this we set CCACHE_DEPEND=1 which enables ccache's 'depend_only'
strategy. This avoids extra spawning of the pre-processor during
cache misses, with the downside that is it less likely ccache will
find a cache hit after semantically benign compiler flag changes.
This is the lesser of two evils, as otherwise we can't use ccache
at all under msys and remain inside the job time limit.
If people are finding ccache to hurt their pipelines, it can be
disabled by setting the 'CCACHE_DISABLE=1' env variable against
their gitlab fork CI settings.

This reverts commit e8e4298fea.
ensuregroup allows to specify both the acceptable versions of avocado,
and a locked version to be used when avocado is not installed as a system
pacakge. This lets us install avocado in pyvenv/ using "mkvenv.py" and
reuse the distro package on Fedora and CentOS Stream (the only distros
where it's available).
ensuregroup's usage of "(>=..., <=...)" constraints when evaluating
the distro package, and "==" constraints when installing it from PyPI,
makes it possible to avoid conflicts between the known-good version and
a package plugins included in the distro.
This is because package plugins have "==" constraints on the version
that is included in the distro, and, using "pip install avocado==88.1"
on a venv that includes system packages will result in an error:
avocado-framework-plugin-varianter-yaml-to-mux 98.0 requires avocado-framework==98.0, but you have avocado-framework 88.1 which is incompatible.
avocado-framework-plugin-result-html 98.0 requires avocado-framework==98.0, but you have avocado-framework 88.1 which is incompatible.
But at the same time, if the venv does not include a system distribution
of avocado then we can install a known-good version and stick to LTS
releases.

The Postcopy preempt capability is expected to be set before incoming
starts, so change the postcopy tests to start with deferred incoming and
call migrate-incoming after the cap has been set.
Why the existing tests (without this patch) didn't fail?
There could be two reasons:
1) "backlog" specifies the number of pending connections. As long as the
server accepts the connections faster than the clients side connecting,
connection will succeed. For the preempt test, it uses only 2 channels,
so very likely to not have pending connections.
2) per my tests (on kernel 6.2), the number of pending connections allowed
is actually "backlog + 1", which is 2 in this case.
That said, the implementation of socket_start_incoming_migration_internal
expects "migrate defer" to be used, and for safety, change the test to
work with the expected usage.

The virtio-gpu test is known to be flaky - that's why we also did
not enable the test_s390x_fedora in the gitlab CI. However, a flaky
test can also be annoying when testing locally, so let's rather skip
this subtest by default and start running the test_s390x_fedora test
in the gitlab CI again (since the other things that are tested here
are quite valuable).

The tests from tests/avocado/migration.py do not work at all
on s390x - the bios shuts down immediately when it cannot find
a boot disk, so there is nothing left to migrate here. For doing
a proper migration test, we would need a proper payload, but we
already do such tests in the migration *qtest*, so it is unnecessary
to redo such a test here, thus let's simply remove this test.

The test attaches a SCSI controller to a non-zero slot and a pcie-to-pci bridge
on slot 0 on the same pcie-root-port. Since a downstream device can be attached
to a pcie-root-port only on slot 0, the above test configuration is not allowed.
Additionally using pcie.0 as id for pcie-to-pci bridge is incorrect as that id
is reserved only for the root bus.
In the test scenario, there is no need to attach a pcie-root-port to the
root complex. A SCSI controller can be attached to a pcie-to-pci bridge
which can then be directly attached to the root bus (pcie.0).
Fix the test and simplify it.

The migration test cases that actually exercise live migration want to
ensure there is a minimum of two iterations of pre-copy, in order to
exercise the dirty tracking code.
Historically we've queried the migration status, looking for the
'dirty-sync-count' value to increment to track iterations. This was
not entirely reliable because often all the data would get transferred
quickly enough that the migration would finish before we wanted it
to. So we massively dropped the bandwidth and max downtime to
guarantee non-convergance. This had the unfortunate side effect
that every migration took at least 30 seconds to run (100 MB of
dirty pages / 3 MB/sec).
This optimization takes a different approach to ensuring that a
mimimum of two iterations. Rather than waiting for dirty-sync-count
to increment, directly look for an indication that the source VM
has dirtied RAM that has already been transferred.
On the source VM a magic marker is written just after the 3 MB
offset. The destination VM is now montiored to detect when the
magic marker is transferred. This gives a guarantee that the
first 3 MB of memory have been transferred. Now the source VM
memory is monitored at exactly the 3MB offset until we observe
a flip in its value. This gives us a guaranteed that the guest
workload has dirtied a byte that has already been transferred.
Since we're looking at a place that is only 3 MB from the start
of memory, with the 3 MB/sec bandwidth, this test should complete
in 1 second, instead of 30 seconds.
Once we've proved there is some dirty memory, migration can be
set back to full speed for the remainder of the 1st iteration,
and the entire of the second iteration at which point migration
should be complete.
On a test machine this further reduces the migration test time
from 8 minutes to 1 minute 40.

Test that we can successfully parse the docs/config/q35-emulated.cfg,
docs/config/q35-virtio-graphical.cfg and docs/config/q35-virtio-serial.cfg
config files (the "...-serial.cfg" file is a subset of the graphical
config file, so we skip that in quick mode).
These config files use two hard-coded image names which we have to
replace with unique temporary files to avoid race conditions in case
the tests are run in parallel. So after creating the temporary image
files, we also have to create a copy of the config file where we
replaced the hard-coded image names.
If KVM is not available, we also have to disable the "accel" lines.
Once everything is in place, we can start QEMU with the modified
config file and check that everything is available in QEMU.

This patch introduces the RISC-V Zfa extension, which introduces
additional floating-point instructions:
* fli (load-immediate) with pre-defined immediates
* fminm/fmaxm (like fmin/fmax but with different NaN behaviour)
* fround/froundmx (round to integer)
* fcvtmod.w.d (Modular Convert-to-Integer)
* fmv* to access high bits of float register bigger than XLEN
* Quiet comparison instructions (fleq/fltq)
Zfa defines its instructions in combination with the following extensions:
* single-precision floating-point (F)
* double-precision floating-point (D)
* quad-precision floating-point (Q)
* half-precision floating-point (Zfh)
Since QEMU does not support the RISC-V quad-precision floating-point
ISA extension (Q), this patch does not include the instructions that
depend on this extension. All other instructions are included in this
patch.
The Zfa specification can be found here:
https://github.com/riscv/riscv-isa-manual/blob/master/src/zfa.tex
The Zfa specifciation is frozen and is in public review since May 3, 2023:
https://groups.google.com/a/groups.riscv.org/g/isa-dev/c/SED4ntBkabg
The patch also includes a TCG test for the fcvtmod.w.d instruction.
The test cases test for correct results and flag behaviour.
Note, that the Zfa specification requires fcvtmod's flag behaviour
to be identical to a fcvt with the same operands (which is also
tested).

For the outer product set of insns, which take an entire matrix
tile as output, the argument is not a combined tile+column.
Therefore using get_tile_rowcol was incorrect, as we extracted
the tile number from itself.
The test case relies only on assembler support for SME, since
no release of GCC recognizes -march=armv9-a+sme yet.

[PMM: dropped now-unneeded changes to sysregs CFLAGS]
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
Some assemblers will complain about attempts to access
id_aa64zfr0_el1 and id_aa64smfr0_el1 by name if the test
binary isn't built for the right processor type:
/tmp/ccASXpLo.s:782: Error: selected processor does not support system register name 'id_aa64zfr0_el1'
/tmp/ccASXpLo.s:829: Error: selected processor does not support system register name 'id_aa64smfr0_el1'
However, these registers are in the ID space and are guaranteed to
read-as-zero on older CPUs, so the access is both safe and sensible.
Switch to using the S syntax, as we already do for ID_AA64ISAR2_EL1
and ID_AA64MMFR2_EL1. This allows us to drop the HAS_ARMV9_SME check
and the makefile machinery to adjust the CFLAGS for this test, so we
don't rely on having a sufficiently new compiler to be able to check
these registers.
This means we're actually testing the SME ID register: no released
GCC yet recognizes -march=armv9-a+sme, so that was always skipped.
It also avoids a future problem if we try to switch the "do we have
SME support in the toolchain" check from "in the compiler" to "in the
assembler" (at which point we would otherwise run into the above
errors).

It was hard to track down this leak as it was an internal allocation
by glib and the backtraces did not give much away. The autofree was
freeing the allocation with g_free() but not taking care of the
individual strings. They should have been freed with g_strfreev()
instead.
Searching the glib source code for the correct string free function
led to:
G_DEFINE_AUTO_CLEANUP_FREE_FUNC(GStrv, g_strfreev, NULL)
and indeed if you read to the bottom of the documentation page you
will find:
typedef gchar** GStrv;
A typedef alias for gchar**. This is mostly useful when used together with g_auto().
So fix up all the g_autofree g_strsplit case that smugly thought they
had de-allocation covered.

The lack of SVE memory instrumentation has been an omission in plugin
handling since it was introduced. Fortunately we can utilise the
probe_* functions to force all all memory access to follow the slow
path. We do this by checking the access type and presence of plugin
memory callbacks and if set return the TLB_MMIO flag.
We have to jump through a few hoops in user mode to re-use the flag
but it was the desired effect:
./qemu-system-aarch64 -display none -serial mon:stdio \
-M virt -cpu max -semihosting-config enable=on \
-kernel ./tests/tcg/aarch64-softmmu/memory-sve \
-plugin ./contrib/plugins/libexeclog.so,ifilter=st1w,afilter=0x40001808 -d plugin

We still need to base this on Debian Sid until riscv64 is promoted to
a release architecture (or another distro provides a full cross
compile target). We use the new qemu-minimal project description to
avoid bringing in all the extra dependencies because every extra
package is another chance for sid to fail.

This is a very bare bones set of dependencies for a minimal build of
QEMU. This will be useful for minimal cross-compile sanity check based
on things like Debian Sid where stuff isn't always in sync.

We need a native compiler to build the hexagon codegen tools. In our
current images we already have a gcc as a side effect of a broken
dependency between gcovr and lcov but this will be fixed when we move
to bookworm. See
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=987818 for details.
Update the packages while we are at it.

We recently missed a regression that should have been picked up by
check-tcg. This was because the libmem plugin is effectively a NOP if
the user doesn't specify the type to use.
Rather than changing the default behaviour add an additional expansion
so we can take this into account in future.

The stack array is only referenced from the start-up code (which is
shared between the s390-ccw.img and the s390-netboot.img), but it is
currently declared twice, once in main.c and once in netmain.c.
It makes more sense to declare this in start.S instead - which will
also be helpful in the next patch, since we need to mention the .bss
section in start.S in that patch.
While we're at it, let's also drop the huge alignment of the stack,
since there is no technical requirement for aligning it to page
boundaries.

This is a better regression test for the bugs hidden by commit 80fc5d26
('graph-lock: Disable locking for now'). With that commit reverted, it
hangs instantaneously and reliably for me.
It is important to have a reliable test like this, because the following
commits will set out to fix the actual root cause of the deadlocks and
then finally revert commit 80fc5d26, which was only a stopgap solution.

This is a perfectly natural occurrence for x86 "rep movb",
where the "rep" prefix forms a counted loop of the one insn.
During the tests/tcg/multiarch/memory test, this logging is
triggered over 350000 times. Within the context of cross-i386-tci
build, which is already slow by nature, the logging is sufficient
to push the test into timeout.

Unlike other subprojects, these require an overlay directory to include
meson rules to build the libraries. The rules are basically lifted
from tests/fp/meson.build, with a few changes to create platform.h
and publish a dependency.
The build defines are passed through a subproject option, and posted
back to users of the library via the dependency's compile_args.
The only remaining user of GIT_SUBMODULES and GIT_SUBMODULES_ACTION
is roms/SLOF, which is used to build pc-bios/s390-ccw. All other
roms submodules are only present to satisfy the license on pre-built
firmware blobs.

This reverts commits eea2d14117 ("Makefile: remove $(TESTS_PYTHON)",
2023-05-26) and 9c6692db55 ("tests: Use configure-provided pyvenv for
tests", 2023-05-18).
Right now, there is a conflict between wanting a ">=" constraint when
using a distro-provided package and wanting a "==" constraint when
installing Avocado from PyPI; this would provide the best of both worlds
in terms of resiliency for both distros that have required packages and
distros that don't.
The conflict is visible also for meson, where we would like to install
the latest 0.63.x version but also accept a distro 1.1.x version.
But it is worse for avocado, for two reasons:
1) we cannot use an "==" constraint to install avocado if the venv
includes a system avocado. The distro will package plugins that have
"==" constraints on the version that is included in the distro, and, using
"pip install avocado==88.1" on a venv that includes system packages will
result in this error:
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
avocado-framework-plugin-varianter-yaml-to-mux 98.0 requires avocado-framework==98.0, but you have avocado-framework 88.1 which is incompatible.
avocado-framework-plugin-result-html 98.0 requires avocado-framework==98.0, but you have avocado-framework 88.1 which is incompatible.
make[1]: Leaving directory '/home/berrange/src/virt/qemu/build'
2) we cannot use ">=" either if the venv does _not_ include a system
avocado, because that would result in the installation of v101.0 which
is the one we've just reverted.
So the idea is to encode the dependencies as an (acceptable, locked)
tuple, like this hypothetical TOML that would be committed inside
python/ and used by mkvenv.py:
[meson]
meson = { minimum = "0.63.0", install = "0.63.3", canary = "meson" }
[docs]
# 6.0 drops support for Python 3.7
sphinx = { minimum = "1.6", install = "<6.0", canary = "sphinx-build" }
sphinx_rtd_theme = { minimum = "0.5" }
[avocado]
avocado-framework = { minimum = "88.1", install = "88.1", canary = "avocado" }
Once this is implemented, it would also be possible to install avocado in
pyvenv/ using "mkvenv.py ensure", thus using the distro package on Fedora
and CentOS Stream (the only distros where it's available). But until
this is implemented, keep avocado in a separate venv. There is still the
benefit of using a single python for meson custom_targets and for sphinx.

This reverts commit ec5ffa0056.
Bumping avocado to version 101 has two issues. First, there are problems
where Avocado is not logging of command lines or terminal output, and not
collecting Python logs outside the avocado namespace.
Second, the recent changes to Python handling mean that there is a single
virtual environment for all the build, instead of a separate one for testing.
Requiring a too-new version of avocado causes conflicts with any avocado
plugins installed on the host:
$ make check-venv
make[1]: Entering directory '/home/berrange/src/virt/qemu/build'
GIT ui/keycodemapdb tests/fp/berkeley-testfloat-3 tests/fp/berkeley-softfloat-3 dtc
VENVPIP install -e /home/berrange/src/virt/qemu/python/
VENVPIP install -r /home/berrange/src/virt/qemu/tests/requirements.txt
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
avocado-framework-plugin-varianter-yaml-to-mux 98.0 requires avocado-framework==98.0, but you have avocado-framework 101.0 which is incompatible.

To avoid this issue, tests/requirements.txt should use a ">=" constraint
and the version of Avocado should be limited to what distros provide
in the system packages. Only Fedora has Avocado, and more specifically
version 92.0 (though 98.0 is also available as a module). As a first
step, this patch reverts the introduction of a too-new Avocado.

qatomic_mb_read and qatomic_mb_set were the very first atomic primitives
introduced for QEMU; their semantics are unclear and they provide a false
sense of safety.
The last use of qatomic_mb_read() has been removed, so delete it.
qatomic_mb_set() instead can survive as an optimized
qatomic_set()+smp_mb(), similar to Linux's smp_store_mb(), but
rename it to qatomic_set_mb() to match the order of the two
operations.

We have several limitations and bugs worth fixing; they are
inter-related enough that it is not worth splitting this patch into
smaller pieces:
* ".5k" should work to specify 512, just as "0.5k" does
* "1.9999k" and "1." + "9"*50 + "k" should both produce the same
result of 2048 after rounding
* "1." + "0"*350 + "1B" should not be treated the same as "1.0B";
underflow in the fraction should not be lost
* "7.99e99" and "7.99e999" look similar, but our code was doing a
read-out-of-bounds on the latter because it was not expecting ERANGE
due to overflow. While we document that scientific notation is not
supported, and the previous patch actually fixed
qemu_strtod_finite() to no longer return ERANGE overflows, it is
easier to pre-filter than to try and determine after the fact if
strtod() consumed more than we wanted. Note that this is a
low-level semantic change (when endptr is not NULL, we can now
successfully parse with a scale of 'E' and then report trailing
junk, instead of failing outright with EINVAL); but an earlier
commit already argued that this is not a high-level semantic change
since the only caller passing in a non-NULL endptr also checks that
the tail is whitespace-only.

[eblake: tweak function comment for accuracy]
Previous patches changed all integral qemu_strto*() error paths to
guarantee that *value is never left uninitialized. Do likewise for
qemu_strtod. Also, tighten qemu_strtod_finite() to never return a
non-finite value (prior to this patch, we were rejecting "inf" with
-EINVAL and unspecified result 0.0, but failing "9e999" with -ERANGE
and HUGE_VAL - which is infinite on IEEE machines - despite our
function claiming to recognize only finite values).
Auditing callers, we have no external callers of qemu_strtod, and
among the callers of qemu_strtod_finite:
- qapi/qobject-input-visitor.c:qobject_input_type_number_keyval() and
qapi/string-input-visitor.c:parse_type_number() which reject all
errors (does not matter what we store)
- utils/cutils.c:do_strtosz() incorrectly assumes that *endptr points
to '.' on all failures (that is, it is not distinguishing between
EINVAL and ERANGE; and therefore still does the WRONG THING for
"9.9e999". The change here does not entirely fix that (a later
patch will tackle this more systematically), but at least it fixes
the read-out-of-bounds first diagnosed in
https://gitlab.com/qemu-project/qemu/-/issues/1629

Rather than open-coding two different ways to check for an unwanted
negative sign, reuse the same code in both functions. That way, if we
decide down the road to accept "-0" instead of rejecting it, we have
fewer places to change. Also, it means we now get ERANGE instead of
EINVAL for negative values in qemu_strtosz, which is reasonable for
what it represents. This in turn changes the expected output of a
couple of iotests.
The change is not quite complete: negative fractional scaled values
can trip us up. This will be fixed in a later patch addressing other
issues with fractional scaled values.

Our goal in writing qemu_strtoi() and friends is to have an interface
harder to abuse than libc's strtol(). Leaving the return value
uninitialized on some but not all error paths does not lend itself
well to this goal; and our documentation wasn't helpful on what to
expect.
Note that the previous patch changed all qemu_strtosz() EINVAL error
paths to slam value to 0 rather than stay uninitialized, even when the
EINVAL eror occurs because of trailing junk. But for the remaining
integral qemu_strto*, it's easier to return the parsed value than to
force things back to zero, in part because of how check_strtox_error
works; in part because people expect that from libc strto* (while
there is no libc strtosz to compare to), and in part because doing so
creates less churn in the testsuite.
Here, the list of affected callers is much longer ('git grep
"qemu_strto[ui]" "*.c" "**/*.c" | grep -v tests/ |wc -l' outputs 107,
although a few of those are the implementation in in cutils.c), so
touching as little as possible is the wisest course of action.

Making callers determine whether or not *value was populated on error
is not nice for usability. Pre-patch, we have unit tests that check
that *result is left unchanged on most EINVAL errors and set to 0 on
many ERANGE errors. This is subtly different from libc strtoumax()
behavior which returns UINT64_MAX on ERANGE errors, as well as
different from our parse_uint() which slams to 0 on EINVAL on the
grounds that we want our functions to be harder to mis-use than
strtoumax().
Let's audit callers:
- hw/core/numa.c:parse_numa() fixed in the previous patch to check for
errors
- migration/migration-hmp-cmds.c:hmp_migrate_set_parameter(),
monitor/hmp.c:monitor_parse_arguments(),
qapi/opts-visitor.c:opts_type_size(),
qapi/qobject-input-visitor.c:qobject_input_type_size_keyval(),
qemu-img.c:cvtnum_full(), qemu-io-cmds.c:cvtnum(),
target/i386/cpu.c:x86_cpu_parse_featurestr(), and
util/qemu-option.c:parse_option_size() appear to reject all failures
(although some with distinct messages for ERANGE as opposed to
EINVAL), so it doesn't matter what is in the value parameter on
error.
- All remaining callers are in the testsuite, where we can tweak our
expectations to match our new desired behavior.
Advancing to the end of the string parsed on overflow (ERANGE), while
still returning 0, makes sense (UINT64_MAX as a size is unlikely to be
useful); likewise, our size parsing code is complex enough that it's
easier to always return 0 when endptr is NULL but trailing garbage was
found, rather than trying to return the value of the prefix actually
parsed (no current caller cared about the value of the prefix).

No need to copy-and-paste lots of boilerplate per string tested, when
we can consolidate that behind helper functions. Plus, this adds a
bit more coverage (we now test all strings both with and without
endptr, whereas before some tests skipped the NULL endptr case), which
exposed a SEGFAULT on qemu_strtosz(NULL, NULL, &val) that will be
fixed in an upcoming patch.
Note that duplicating boilerplate has one advantage lost here - a
failed test tells you which line number failed; but a helper function
does not show the call stack that reached the failure. Since we call
the helper more than once within many of the "unit tests", even the
unit test name doesn't point out which call is failing. But that only
matters when tests fail (they normally pass); at which point I'm
debugging the failures under gdb anyways, so I'm not too worried about
it.

A quick search for 'qemu_strtosz' in the code base shows that outside
of the testsuite, the ONLY place that passes a non-NULL pointer to
@endptr of any variant of a size parser is in hmp.c (the 'o' parser of
monitor_parse_arguments), and that particular caller warns of
"extraneous characters at the end of line" unless the trailing bytes
are purely whitespace. Thus, it makes no semantic difference at the
high level whether we parse "1.5e1k" as "1" + ".5e1" + "k" (an attempt
to use scientific notation in strtod with a scaling suffix of 'k' with
no trailing junk, but which qemu_strtosz says should fail with
EINVAL), or as "1.5e" + "1k" (a valid size with scaling suffix of 'e'
for exabytes, followed by two junk bytes) - either way, any user
passing such a string will get an error message about a parse failure.
However, an upcoming patch to qemu_strtosz will fix other corner case
bugs in handling the fractional portion of a size, and in doing so, it
is easier to declare that qemu_strtosz() itself stops parsing at the
first 'e' rather than blindly consuming whatever strtod() will
recognize. Once that is fixed, the difference will be visible at the
low level (getting a valid parse with trailing garbage when @endptr is
non-NULL, while continuing to get -EINVAL when @endptr is NULL); this
is easier to demonstrate by moving the affected strings from
test_qemu_strtosz_invalid() (which declares them as always -EINVAL) to
test_qemu_strtosz_trailing() (where @endptr affects behavior, for now
with FIXME comments).
Note that a similar argument could be made for having "0x1.5" or
"0x1M" parse as 0x1 with ".5" or "M" as trailing junk, instead of
blindly treating it as -EINVAL; however, as these cases do not suffer
from the same problems as floating point, they are not worth changing
at this time.

It's hard to tweak code for consistency if I can't prove what will or
won't break from those tweaks. Time to add unit tests for
qemu_strtod() and qemu_strtod_finite().
Among other things, I wrote a check whether we have C99 semantics for
strtod("0x1") (which MUST parse hex numbers) rather than C89 (which
must stop parsing at 'x'). These days, I suspect that is okay; but if
it fails CI checks, knowing the difference will help us decide what we
want to do about it. Note that C2x, while not final at the time of
this patch, has been considering whether to make strtol("0b1") parse
as 1 with no slop instead of the C17 parse of 0 with slop "b1"; that
decision may also bleed over to strtod(). But for now, I didn't think
it worth adding unit tests on that front (to strtol or strtod) as
things may still change.
Likewise, there are plenty more corner cases of strtod proper that I
don't explicitly test here, but there are enough unit tests added here
that it covers all the branches reached in our wrappers. In
particular, it demonstrates the difference on when *value is left
uninitialized, which an upcoming patch will normalize.

It's already confusing that we have two very similar functions for
wrapping the parse of a 64-bit unsigned value, differing mainly on
whether they permit leading '-'. Adjust the signature of parse_uint()
and parse_uint_full() to be like all of qemu_strto*(): put the result
parameter last, use the same types (uint64_t and unsigned long long
have the same width, but are not always the same type), and mark
endptr const (this latter change only affects the rare caller of
parse_uint). Adjust all callers in the tree.
While at it, note that since cutils.c already includes:
QEMU_BUILD_BUG_ON(sizeof(int64_t) != sizeof(long long));
we are guaranteed that the result of parse_uint* cannot exceed
UINT64_MAX (or the build would have failed), so we can drop
pre-existing dead comparisons in opts-visitor.c that were never false.

While we were matching 32-bit strtol in qemu_strtoi, our use of a
64-bit parse was leaking through for some inaccurate answers in
qemu_strtoui in comparison to a 32-bit strtoul (see the unit test for
examples). The comment for that function even described what we have
to do for a correct parse, but didn't implement it correctly: since
strtoull checks for overflow against the wrong values and then
negates, we have to temporarily undo negation before checking for
overflow against our desired value.
Our int wrappers would be a lot easier to write if libc had a
guaranteed 32-bit parser even on platforms with 64-bit long.
Whether we parse C2x binary strings like "0b1000" is currently up to
what libc does; our unit tests intentionally don't cover that at the
moment, though.

We have quite a few undertested and underdocumented integer parsing
corner cases. To ensure that any changes we make in the code are
intentional rather than accidental semantic changes, it is time to add
more unit tests of existing behavior.
In particular, this demonstrates that parse_uint() and qemu_strtou64()
behave differently. For "-0", it's hard to argue why parse_uint needs
to reject it (it's not a negative integer), but the documentation sort
of mentions it; but it is intentional that all other negative values
are treated as ERANGE with value 0 (compared to qemu_strtou64()
treating "-2" as success and UINT64_MAX-1, for example).
Also, when mixing overflow/underflow with a check for no trailing
junk, parse_uint_full favors ERANGE over EINVAL, while qemu_strto[iu]*
favor EINVAL. This behavior is outside the C standard, so we can pick
whatever we want, but it would be nice to be consistent.
Note that C requires that "9223372036854775808" fail strtoll() with
ERANGE/INT64_MAX, but "-9223372036854775808" pass with INT64_MIN; we
weren't testing this. For strtol(), the behavior depends on whether
long is 32- or 64-bits (the cutoff point either being the same as
strtoll() or at "-2147483648"). Meanwhile, C is clear that
"-18446744073709551615" pass stroull() (but not strtoll) with value 1,
even though we want it to fail parse_uint(). And although
qemu_strtoui() has no C counterpart, it makes more sense if we design
it like 32-bit strtoul() (that is, where "-4294967296" be an alternate
acceptable spelling for "1", but "-0xffffffff00000001" should be
treated as overflow and return 0xffffffff rather than 1). We aren't
there yet, so some of the tests added in this patch have FIXME
comments.
However, note that C2x will (likely) be adding a SILENT semantic
change, where C17 strtol("0b1", &ep, 2) returns 0 with ep="b1", but
C2x will have it return 1 with ep="". I did not feel like adding
testing for those corner cases, in part because the next version of C
is not standard and libc support for binary parsing is not yet
wide-spread (as of this patch, glibc.git still misparses bare "0b":
https://sourceware.org/bugzilla/show_bug.cgi?id=30371).

by comparison to libc strto*); there, *value is untouched for NULL

There are 27 pre-copy live migration scenarios being tested. In all of
these we force non-convergence and run for one iteration, then let it
converge and wait for completion during the second (or following)
iterations. At 3 mbps bandwidth limit the first iteration takes a very
long time (~30 seconds).
While it is important to test the migration passes and convergence
logic, it is overkill to do this for all 27 pre-copy scenarios. The
TLS migration scenarios in particular are merely exercising different
code paths during connection establishment.
To optimize time taken, switch most of the test scenarios to run
non-live (ie guest CPUs paused) with no bandwidth limits. This gives
a massive speed up for most of the test scenarios.
For test coverage the following scenarios are unchanged
* Precopy with UNIX sockets
* Precopy with UNIX sockets and dirty ring tracking
* Precopy with XBZRLE
* Precopy with UNIX compress
* Precopy with UNIX compress (nowait)
* Precopy with multifd
On a test machine this reduces execution time from 13 minutes to
8 minutes.

Change the migration test to use the new qtest event callback to watch

All callers now pass is_external=false to aio_set_fd_handler() and
aio_set_event_notifier(). The aio_disable_external() API that
temporarily disables fd handlers that were registered is_external=true
is therefore dead code.
Remove aio_disable_external(), aio_enable_external(), and the
is_external arguments to aio_set_fd_handler() and
aio_set_event_notifier().
The entire test-fdmon-epoll test is removed because its sole purpose was
testing aio_disable_external().

POWER9 DD2.1 and earlier had significant limitations when running KVM,
including lack of "mixed mode" MMU support (ability to run HPT and RPT
mode on threads of the same core), and a translation prefetch issue
which is worked around by disabling "AIL" mode for the guest.
These processors are not widely available, and it's difficult to deal
with all these quirks in qemu +/- KVM, so create a POWER9 DD2.2 CPU
and make it the default POWER9 CPU.

The order in which instructions are generated by gen_insn() influences
assignment to tmp registers. During generation, tmp instructions (e.g.
generate_V6_vassign_tmp) use vreg_src_off() to determine what kind of
register to use as source. If some instruction (e.g.
generate_V6_vmpyowh_64_acc) uses a tmp register but is generated prior
to the corresponding tmp instruction, the vregs_updated_tmp bit map
isn't updated in time.
Exmple:
{ v14.tmp = v16; v25 = v14 } This works properly because
generate_V6_vassign_tmp is generated before generate_V6_vassign
and the bit map is updated.
{ v15:14.tmp = vcombine(v21, v16); v25:24 += vmpyo(v18.w,v14.h) }
This does not work properly because vmpyo is generated before
vcombine and therefore the bit map does not yet know that there's
a tmp register.
The parentheses in the decoding function were in the wrong place.
Moving them to the correct location makes shuffling of .tmp vector
registers work as expected.

We cannot use the generic reentrancy guard in the LSI code, so
we have to manually prevent endless reentrancy here. The problematic
lsi_execute_script() function has already a way to detect whether
too many instructions have been executed - we just have to slightly
change the logic here that it also takes into account if the function
has been called too often in a reentrant way.
The code in fuzz-lsi53c895a-test.c has been taken from an earlier
patch by Mauro Matteo Cascella.

Test if the audio subsystem can handle extreme up- and down-
sampling ratios like 44100/1 and 1/44100. For some time these
used to trigger QEMU aborts. The test was taken from
https://gitlab.com/qemu-project/qemu/-/issues/71 where it was
used to demonstrate a very different issue.

Though we are already using CONFIG_RTL8139_PCI in the meson.build file
for testing whether the rtl8139 device is available or not, this is not
enough: The CONFIG switch might have been selected by another target
(e.g. the mips fuloong2e machine has the rtl8139 chip soldered on the
board), so CONFIG_RTL8139_PCI ends up in config_all_devices and the
test then gets executed on x86. We need an additional run-time check
to be on the safe side to make this test also work when configure has
been run with "--without-default-devices".

Clean up monitor_event to just use monitor_suspend/monitor_resume,
using mon->mux_out to protect against incorrect nesting (especially
on startup).
The only remaining case of reading suspend_cnt is in the can_read
callback, which is just advisory and can use qatomic_read.
As an extra benefit, mux_out is now simply protected by mon_lock.
Also, moving the prompt to the beginning of the main loop removes
it from the output in some error cases where QEMU does not actually
start successfully. It is not a full fix and it would be nice to
also remove the monitor heading, but this is already a small (though
unintentional) improvement.

Perform the function selection once, and only if CONFIG_AVX512_OPT

spreading the init across 3 files.
Remove xbzrle-bench.c. The benefit of being able to benchmark

Biosbits avocado tests on gitlab has thus far been disabled because some
packages needed by this test was missing in the container images used by gitlab
CI. These packages have now been added with the commit:
da9000784c ("tests/lcitool: Add mtools and xorriso and remove genisoimage as dependencies")
Therefore, this change enables bits avocado test on gitlab.
At the same time, the bits cleanup code has also been made more robust with

Skip TestBlockdevReopen.test_insert_compress_filter() if the 'compress'
driver isn't available.
In order to make the test succeed when the case is skipped, we also need
to remove any output from it (which would be missing in the case where
we skip it). This is done by replacing qemu_io_log() with qemu_io(). In
case of failure, qemu_io() raises an exception with the output of the
qemu-io binary in its message, so we don't actually lose anything.

This commit enables each CXL Type-3 device to contain one volatile
memory region and one persistent region.
Two new properties have been added to cxl-type3 device initialization:
[volatile-memdev] and [persistent-memdev]
The existing [memdev] property has been deprecated and will default the
memory region to a persistent memory region (although a user may assign
the region to a ram or file backed region). It cannot be used in
combination with the new [persistent-memdev] property.
Partitioning volatile memory from persistent memory is not yet supported.
Volatile memory is mapped at DPA(0x0), while Persistent memory is mapped
at DPA(vmem->size), per CXL Spec 8.2.9.8.2.0 - Get Partition Info.

In the previous commit, we modified gdbstub.c to only send stop-reply
packets as a response to GDB commands that accept it. Now, let's add a
test for this intended behavior. Running this test before the fix from
the previous commit fails as QEMU sends a stop-reply packet
asynchronously, when GDB was in fact waiting an ACK.

Each slot in a packet can be assigned to at most one instruction.
Although the assembler generally ought to enforce this rule, we better
be safe than sorry and also do some check to properly throw an "invalid
packet" exception on wrong slot assignments.
This should also make it easier to debug possible future errors caused
by missing updates to `find_iclass_slots()` rules in
target/hexagon/iclass.c.

Several debian-based tests need the python3-venv dependency as a
consequence of Debian debundling the "ensurepip" module normally
included with Python.
As mkvenv.py stands as of this commit, Debian requires EITHER:
(A) setuptools and pip, or
(B) ensurepip
mkvenv is a few seconds faster if you have setuptools and pip, so
developers should prefer the first requirement. For the purposes of CI,
the time-save is a wash; it's only a matter of who is responsible for
installing pip and when; the timing is about the same.
Arbitrarily, I chose adding ensurepip to the test configuration because
it is normally part of the Python stdlib, and always having it allows us
a more consistent cross-platform environment.

Bios bits avocado tests need mformat (provided by the mtools package) and
xorriso tools in order to run within gitlab CI containers. Add those
dependencies within the Dockerfiles so that containers can be built with
those tools present and bios bits avocado tests can be run there.
xorriso package conflicts with genisoimage package on some distributions.
Therefore, it is not possible to have both the packages at the same time
in the container image uniformly for all distribution flavors. Further,
on some distributions like RHEL, both xorriso and genisoimage
packages provide /usr/bin/genisoimage and on some other distributions like
Fedora, only genisoimage package provides the same utility.
Therefore, this change removes the dependency on geninsoimage for building
container images altogether keeping only xorriso package. At the same time,
cdrom-test.c is updated to use and check for existence of only xorrisofs.

The qmp_discard_response method simply ignores the result of the QMP
command, merely unref'ing the object. This is a bad idea for tests
as it leaves no trace if the QMP command unexpectedly failed. The
qtest_qmp_assert_success method will validate that the QMP command
returned without error, and if errors occur, it will print a message
on the console aiding debugging.

We can have failure with the inet type test because the port address
is not allocated atomically and can be taken by another test between its
selection and the start of QEMU. To avoid that, use an unix socket with
a path that is unique

As the cached assets have fallen out of our cache new attempts to
fetch these binaries fail hard due to certificate expiry. It's hard
to find a contact email for the domain as the root page of mipsdistros
throws up some random XML. I suspect Amazon are merely the hosts.
The checksums should protect us from any man-in-the-middle type
attacks.

test-bdrv-drain contains a few test cases that are run both in coroutine
and non-coroutine context. Running the entire code including the setup
and shutdown in coroutines is incorrect because graph modifications can
generally not happen in coroutines.
Change the test so that creating and destroying the test nodes and
BlockBackends always happens outside of coroutine context.

This is a regression test for the recent fix that changed

Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
The QAPI schema doc comment language provides special syntax for
command and event arguments, struct and union members, alternate
branches, enumeration values, and features: descriptions starting with
"@name:".
By convention, we format them like this:
# @name: Lorem ipsum dolor sit amet, consectetur adipiscing elit,
# sed do eiusmod tempor incididunt ut labore et dolore
# magna aliqua.
Okay for names as short as "name", but we have much longer ones. Their
description gets squeezed against the right margin, like this:
# @dirty-sync-missed-zero-copy: Number of times dirty RAM synchronization could
# not avoid copying dirty pages. This is between
# 0 and @dirty-sync-count * @multifd-channels.
# (since 7.1)
The description text is effectively just 50 characters wide. Easy
enough to read, but can be cumbersome to write.
The awkward squeeze against the right margin makes people go beyond it,
which produces two undesirables: arguments about style, and descriptions
that are unnecessarily hard to read, like this one:
# @postcopy-vcpu-blocktime: list of the postcopy blocktime per vCPU. This is
# only present when the postcopy-blocktime migration capability
# is enabled. (Since 3.0)
We could instead format it like
# @postcopy-vcpu-blocktime:
# list of the postcopy blocktime per vCPU. This is only present
# when the postcopy-blocktime migration capability is
# enabled. (Since 3.0)
or, since the commit before previous, like
# @postcopy-vcpu-blocktime:
# list of the postcopy blocktime per vCPU. This is only present
# when the postcopy-blocktime migration capability is
# enabled. (Since 3.0)
However, I'd rather have
# @postcopy-vcpu-blocktime: list of the postcopy blocktime per vCPU.
# This is only present when the postcopy-blocktime migration
# capability is enabled. (Since 3.0)
because this is how rST field and option lists work.
To get this, we need to let the first non-blank line after the
"@name:" line determine expected indentation.
This fills up the indentation pitfall mentioned in
docs/devel/qapi-code-gen.rst. A related pitfall still exists. Update
the text to show it.

When an argument's description starts on the line after the "#arg: "
line, indentation is stripped only from the description's first line,
as demonstrated by the previous commit. Moreover, subsequent lines
with less indentation are not rejected.
Make the first line's indentation the expected indentation for the
remainder of the description. This fixes indentation stripping, and
also requires at least that much indentation.

The 'singlestep' HMP command is confusing, because it doesn't
actually have anything to do with single-stepping the CPU. What it
does do is force TCG emulation to put one guest instruction in each
TB, which can be useful in some situations.
Create a new HMP command 'one-insn-per-tb', so we can document that
'singlestep' is just a deprecated synonym for it, and eventually
perhaps drop it.
We aren't obliged to do deprecate-and-drop for HMP commands,
but it's easy enough to do so, so we do.

It is possible to have a build with both TCG and KVM disabled due to
Xen requiring the i386 and x86_64 binaries to be present in an aarch64
host.
If we build with --disable-tcg on the aarch64 host, we will end-up
with a QEMU binary (x86) that does not support TCG nor KVM.
Skip tests that crash or hang in the above scenario. Do not include
any test cases if TCG and KVM are missing.
Make sure that calls to qtest_has_accel are placed after g_test_init
in similar fashion to commit ae4b01b349 ("tests: Ensure TAP version is
printed before other messages") to avoid TAP parsing errors.

We're about to move the 32-bit CPUs under CONFIG_TCG, so adjust the
query-cpu-model-expansion test to check against the cortex-a7, which
is already under CONFIG_TCG. That allows the next patch to contain
only code movement. (All the test cares about is that the CPU type
it's checking is one which definitely doesn't work under KVM.)

Running every plugin with every test is getting excessive as well as
not really improving coverage that much. Restrict the plugin tests to
just the MULTIARCH_TESTS which are shared between most architecture
for both system and user-mode. For those that aren't we need to squash
MULTIARCH_TESTS so we don't add them when they are not part of the
TESTS global.

Commit c0c8687ef0 disabled the
boot_linux.py test-case due to which the code coverage for ppc
decreased by around 2%. As per the discussion on
https://lore.kernel.org/qemu-devel/87sfdpqcy4.fsf@linaro.org/ it
was mentioned that the baseline test for ppc64 could be modified
to make up this 2% code coverage. This patch attempts to achieve
this 2% code coverage by adding various device command line
arguments (to ./qemu-system-ppc64) in the tuxrun_baselines.py
test-case.
The code coverage report with boot_linux.py, without it and finally
with these tuxrun_baselines.py changes is as follows:

test_arm_ast2500_evb_sdk and test_arm_ast2600_evb_sdk are currently
failing. The problem is that they are trying to look for the login
prompt that does not have a newline at the end - but the logic in
_console_interaction() only handles full lines. It used to work by
accident in the past since there were sometimes kernel (warning and
error) messages popping up that finally provided a newline character
in the output, but since the tests have been changed to run with the
"quiet" kernel parameter, this is not working anymore.
To make this work reliably, we must not look for the "login:" prompt,
but have to use some text ending with a newline instead. And in the
ast2600 test, switch to ssh instead of trying to log into the serial
console - this works much more reliable and also has the benefit of
excercising the network interface here a little bit, too.

Avocado version 101.0 has a fix to re-compute the checksum
of an asset file if the algorithm used in the *-CHECKSUM
file isn't the same as the one being passed to it by the
avocado user (i.e. the avocado_qemu python module).
In the earlier avocado versions this fix wasn't there due
to which if the checksum wouldn't match the earlier
checksum (calculated by a different algorithm), the avocado
code would start downloading a fresh image from the internet
URL thus making the test-cases take longer to execute.
Bump up the avocado-framework version to 101.0.

The C code generator fails to honor 'if' conditions of command and
event arguments.
For instance, tests/qapi-schema/qapi-schema-test.json has
{ 'event': 'TEST_IF_EVENT',
'data': { 'foo': 'TestIfStruct',
'bar': { 'type': ['str'], 'if': 'TEST_IF_EVT_ARG' } },
'if': { 'all': ['TEST_IF_EVT', 'TEST_IF_STRUCT'] } }
Generated tests/test-qapi-events.h fails to honor the TEST_IF_EVT_ARG
condition:
#if defined(TEST_IF_EVT) && defined(TEST_IF_STRUCT)
void qapi_event_send_test_if_event(TestIfStruct *foo, strList *bar);
#endif /* defined(TEST_IF_EVT) && defined(TEST_IF_STRUCT) */
Only uses so far are in tests/.
We could fix the generator to emit something like
#if defined(TEST_IF_EVT) && defined(TEST_IF_STRUCT)
void qapi_event_send_test_if_event(TestIfStruct *foo
#if defined(TEST_IF_EVT_ARG)
, strList *bar
#endif
);
#endif /* defined(TEST_IF_EVT) && defined(TEST_IF_STRUCT) */
Ugly. Calls become similarly ugly. Not worth fixing.
Conditional arguments work fine with 'boxed': true, simply because
complex types with conditional members work fine. Not worth breaking.
Reject conditional arguments unless boxed.
Move the tests cases covering unboxed conditional arguments out of
tests/qapi-schema/qapi-schema-test.json. Cover boxed conditional
arguments there instead.

Union TestIfUnion is conditional on macros TEST_IF_UNION and
TEST_IF_STRUCT. It uses TestIfEnum, which is conditional on macro
TEST_IF_ENUM. If TEST_IF_UNION and TEST_IF_STRUCT are defined, but
TEST_IF_ENUM isn't, the generated code won't compile.
Command test-if-cmd is conditional an macros TEST_IF_CMD and
TEST_IF_STRUCT, and uses TestIfEnum. Similar issue.
Event TEST_IF_EVENT is conditional an macros TEST_IF_EVT and

[Commit message corrected]
A union's 'discriminator' must name one of the common members.
QAPISchemaVariants.check() looks it up by its c_name(), then checks
the name matches exactly (because c_name() is not injective).
Tests union-base-empty and union-invalid-discriminator both cover the
case where lookup fails. Repurpose the latter to cover the case where
it succeeds and the name check fails.

[Commit message typo fixed]
A struct's 'data' must be a JSON object defining the struct's members.
The QAPI code generator incorrectly accepts a JSON string instead, and
then crashes in QAPISchema._make_members() called from
._def_struct_type().
Fix to reject it: factor check_type_implicit() out of
check_type_name_or_implicit(), and switch check_struct() to use it
instead. Also add a test case.

According to QEMU's support policy, we stop supporting the previous
major release two years after the the new major release has been
published. So we can stop testing FreeBSD 12 now and should switch
our FreeBSD VM to version 13 instead.
Some changes are needed for this update: The downloadable .ISO images
do not use the serial port as console by default anymore, so they
are not usable in the same way as with FreeBSD 12. Fortunately, the
FreeBSD project now also offers some pre-installed CI images that
have the serial console enabled, so we can use those now, with the
benefit that we can skip almost all parts of the previous installation
process.

As well as some variants of normal non-Xen stuff like MSI to vAPIC and

Currently our NetBSD VM recipe requests instal of the python37 package
and explicitly tells QEMU to use that version of python. Since the
NetBSD base ISO was updated to version 9.3 though, the default system
python version is 3.9 which is sufficiently new for QEMU to rely on.
Rather than requesting an older python, just test against the default

Currently meson registers a single test that invokes an entire group of
I/O tests, hiding the test granularity from meson. There are various
downsides of doing this
* You cannot ask 'meson test' to invoke a single I/O test
* The meson test timeout can't be applied to the individual
tests
* Meson only gets a pass/fail for the overall I/O test group
not individual tests
* If a CI job gets killed by the GitLab timeout, we don't
get visibility into how far through the I/O tests
execution got.
This switches meson to perform test discovery by invoking 'check' in
dry-run mode. It then registers one meson test case for each I/O
test. Parallel execution remains disabled since the I/O tests do not
use self contained execution environments and thus conflict with
each other.

The current test runner is only safe against parallel execution within
a single instance of the 'check' process, and only if -j is given a
value greater than 2. This prevents running multiple copies of the
'check' process for different test scenarios.
This change switches the output / socket directories to always include
the test name, image format and image protocol. This should allow full
parallelism of all distinct test scenarios. eg running both qcow2 and
raw tests at the same time, or both file and nbd tests at the same
time.
It would be possible to allow for parallelism of the same test scenario
by including the pid, but that would potentially let many directories
accumulate over time on failures, so is not done.

Currently the tests have their stdin inherited from the test harness,
meaning they are connected to a TTY. The QEMU processes spawned by
certain tests, however, modify TTY settings and if the test exits
abnormally the settings might not be restored.
The python test harness thus has some logic which will capture the
initial TTY settings and restore them once all tests are finished.
This does not, however, take into account the possibility of many
copies of the 'check' program running in parallel. With parallel
execution, a later invokation may save the TTY state that QEMU has
already modified, and thus restore bad state leaving the TTY
non-functional.
None of the I/O tests shnould actually be interactive requiring
user input and so they should not require a TTY at all. To avoid
this while TTY save/restore complexity we can connect the test
stdin to /dev/null instead.

Recently meson started complaining that TAP test reports don't include

removed from Meson, it looks like good practice to include this header

mode, it prints the paths to the tests relative to the base of the
I/O test directory.
When asking 'check' to run an individual test, however, it mandates that
only the unqualified test name is given, without any path prefix. This
inconsistency makes it harder to ask for a list of tests and then invoke
each one.
Thus the test listing code is change to flatten the test names, by
printing only the base name, which can be directly invoked.

The 'check' script can be invoked in "dry run" mode, in which case it
merely does test discovery and prints out all their names. Despite only
doing test discovery it still validates that the various QEMU binaries
can be found. This makes it impossible todo test discovery prior to
building QEMU. This is a desirable feature to support, because it will
let meson discover tests.
Fortunately the code in the TestEnv constructor is ordered in a way
that makes this fairly trivial to achieve. We can just short circuit
the constructor after the basic directory paths have been set.

The 'check' script has some rather dubious logic whereby it assumes
that if invoked as a symlink, then it is running from a separate
source tree and build tree, otherwise it assumes the current working
directory is a combined source and build tree.
This doesn't work if you want to invoke the 'check' script using
its full source tree path while still using a split source and build
tree layout. This would be a typical situation with meson if you ask
it to find the 'check' script path using files('check').
Rather than trying to make the logic more magical, add support for
explicitly passing the dirs using --source-dir and --build-dir. If
either is omitted the current logic is maintained.

The core of the test was utilising "ethtool -t eth1 offline" to run
through a test sequence. For reasons unknown the test hangs under some
configurations of the build on centos8-stream. Fundamentally running
the old fedora-31 cloud-init is just too much for something that is
directed at testing one device. So we:
- replace fedora with a custom kernel + buildroot rootfs
- rename the test from IGB to NetDevEthtool
- re-factor the common code, add (currently skipped) tests for other
devices which support ethtool
- remove the KVM limitation as its fast enough to run in KVM or TCG

b) Make the loop exit immediately rather than have the sleep
when it does start autoconverge, otherwise the autoconverge
might succeed during the sleep.
c) Reduce inc_pct so auto converge happens more slowly
d) Reduce the max-bandwidth in migrate_ensure_non_converge

Try writing zeroes to a FUSE export while allowing the area to be
unmapped; block/file-posix.c generally implements writing zeroes with
BDRV_REQ_MAY_UNMAP ('write -zu') by calling fallocate(PUNCH_HOLE). This
used to lead to a blk_pdiscard() in the FUSE export, which may or may
not lead to the area being zeroed. HEAD^ fixed this to use
blk_pwrite_zeroes() instead (again with BDRV_REQ_MAY_UNMAP), so verify
that running `qemu-io 'write -zu'` on a FUSE exports always results in
zeroes being written.
