Currently, -smp supports up to 7-levels topology hierarchy:
-drawers/books/sockets/dies/clusters/cores/threads.
Though no machine supports all these 7 levels yet, these 7 levels have
the strict containment relationship and together form the generic CPU
topology representation of QEMU.
Also, note that the maxcpus is calculated by multiplying all 7 levels:
maxcpus = drawers * books * sockets * dies * clusters *
cores * threads.
To cover this code path, it is necessary to test the full topology case
(with all 7 levels). This also helps to avoid introducing new issues by
further expanding the CPU topology in the future.

Since s390 machine supports both "drawers" and "books" in -smp, add the
"drawers" and "books" combination test case to match the actual topology

Although drawer was introduced to -smp along with book by s390 machine,
as a general topology level in QEMU that may be reused by other arches
in the future, it is desirable to cover this parameter's parsing in a
separate case.

Currently, -smp supports 2 more new levels: book and drawer.
It is necessary to consider the effects of book and drawer in the test
cases to ensure that the calculations are correct. This is also the
preparation to add new book and drawer test cases.

The q35 machine is trying to support up to 4096 vCPUs [1], so it's
necessary to bump max_cpus in test-smp-parse to 4096 to cover the
topological needs of future machines.

Add a RISC-V 'virt' machine to the graph. This implementation is a
modified copy of the existing arm machine in arm-virt-machine.c
It contains a virtio-mmio and a generic-pcihost controller. The
generic-pcihost controller hardcodes assumptions from the ARM 'virt'
machine, like ecam and pio_base addresses, so we'll add an extra step to
set its parameters after creating it.
Our command line is incremented with 'aclint' parameters to allow the
machine to run MSI tests.

Checks the reset values of MODER, OTYPER, PUPDR, ODR and IDR.

Checks that a input pin set high or low externally results
in the pin rising and lowering.
- `test_pull_up_pull_down()` :
Checks that a floating pin in pull-up/down mode is actually high/down.

For now, it simply performs instruction, bb and mem count, and ensure
that inline vs callback versions have the same result. Later, we'll
extend it when new inline operations are added.
Use existing plugins to test everything works is a bit cumbersome, as
different events are treated in different plugins. Thus, this new one.

We "fixed" a bug with LTO builds with 100c459f194 (tests/qtest: bump
up QOS_PATH_MAX_ELEMENT_SIZE) but it seems it has triggered again.
The array is sized according to the maximum anticipated length of a
path on the graph. However, the worst case for a depth-first search is
to push all nodes on the graph. So it's not really LTO, it depends on
the ordering of the constructors.
Lets be more assertive raising QOS_PATH_MAX_ELEMENT_SIZE to make it go
away again.

In qvring_init() we're writing vq->used->avail_event at "vq->used + 2 +
array_size". The struct pointed by vq->used is, from virtio_ring.h
Linux header):
* // A ring of used descriptor heads with free-running index.
* __virtio16 used_flags;
* __virtio16 used_idx;
* struct vring_used_elem used[num];
* __virtio16 avail_event_idx;
So 'flags' is the word right at vq->used. 'idx' is vq->used + 2. We need
to skip 'used_idx' by adding + 2 bytes, and then sum the vector size, to
reach avail_event_idx. An example on how to properly access this field
can be found in qvirtqueue_kick():
avail_event = qvirtio_readw(d, qts, vq->used + 4 +
sizeof(struct vring_used_elem) * vq->size);
This error was detected when enabling the RISC-V 'virt' libqos machine.
The 'idx' test from vhost-user-blk-test.c errors out with a timeout in
qvirtio_wait_used_elem(). The timeout happens because when processing
the first element, 'avail_event' is read in qvirtqueue_kick() as non-zero
because we didn't initialize it properly (and the memory at that point
happened to be non-zero). 'idx' is 0.
All of this makes this condition fail because "idx - avail_event" will
overflow and be non-zero:
/* < 1 because we add elements to avail queue one by one */
if ((flags & VRING_USED_F_NO_NOTIFY) == 0 &&
(!vq->event || (uint16_t)(idx-avail_event) < 1)) {
d->bus->virtqueue_kick(d, vq);
}
As a result the virtqueue is never kicked and we'll timeout waiting for it.

The loop isn't setting the values for the last element. Every other
element is being initialized with addr = 0, flags = VRING_DESC_F_NEXT
and next = i + 1. The last elem is never touched.
This became a problem when enabling a RISC-V 'virt' libqos machine in
the 'indirect' test of virti-blk-test.c. The 'flags' for the last
element will end up being an odd number (since we didn't touch it).
Being an odd number it will be mistaken by VRING_DESC_F_NEXT, which
happens to be 1.
Deep into hw/virt/virtio.c, in virtqueue_split_pop(), into
virtqueue_split_read_next_desc(), a check for VRING_DESC_F_NEXT will be
made to see if we're supposed to chain. The code will keep up chaining
in the last element because the uninitialized value happens to be odd.
We'll error out right after that because desc->next (which is also
uninitialized) will be >= max. A VIRTQUEUE_READ_DESC_ERROR will be
returned, with an error message like this in the stderr:
qemu-system-riscv64: Desc next is 49391
Since we never returned, we'll end up timing out at qvirtio_wait_used_elem():
ERROR:../tests/qtest/libqos/virtio.c:236:qvirtio_wait_used_elem:
assertion failed: (g_get_monotonic_time() - start_time <= timeout_us)
The root cause is using uninitialized values from guest_alloc() in
qvring_indirect_desc_setup(). There's no guarantee that the memory pages
retrieved will be zeroed, so we can't make assumptions. In fact, commit
5b4f72f5e8 ("tests/qtest: properly initialise the vring used idx") fixed a
similar problem stating "It is probably not wise to assume guest memory
is zeroed anyway". I concur.
Initialize all elems in qvring_indirect_desc_setup().

The main problem is that "check-venv" is a .PHONY target will always
evaluate and trigger a full re-build of the VM images. While its
tempting to drop it from the dependencies that does introduce a
breakage on freshly configured builds.
Fortunately we do have the otherwise redundant --force flag for the
script which up until now was always on. If we make the usage of
--force conditional on dependencies other than check-venv triggering
the update we can avoid the costly rebuild and still run cleanly on a
fresh checkout.

My default header template is GPLv3 but for QEMU code we really should
stick to GPLv2-or-later (allowing others to up-license it if they
wish). While this is test code we should still be consistent on the
source distribution.
I wrote all of this code so its not a problem. However there remains
one GPLv3 file left which is the crt0-tc2x.S for TriCore.

QAPIDoc stores a reference to QAPIParser just to pass it to
QAPIParseError. The resulting error position depends on the state of
the parser. It happens to be the current comment line. Servicable,
but action at a distance.
The commit before previous moved most uses of QAPIParseError from
QAPIDoc to QAPIParser. There are just three left. Convert them to
QAPISemError. This involves passing info to a few methods. Then drop
the reference to QAPIParser.
The three errors lose the column number. Not really interesting here:
it's the comment line's indentation.

The parser recognizes only the first "Features:" line. Any subsequent
ones are treated as ordinary text, as visible in test case
doc-duplicate-features. Recognize "Features:" lines anywhere. A
second one is an error.
A 'Features:' line without any features is useless, but not an error.
Make it an error. This makes detecting a second "Features:" line
easier.
