bb829cdeff tests/unit/test-smp-parse: Test "parameter=0" SMP configurations
The support for "parameter=0" SMP configurations is removed, and QEMU
returns error for those cases.

So add the related test cases to ensure parameters can't accept 0.

71e44ee0b2 tests/unit/test-smp-parse: Test smp_props.has_clusters
The smp_props.has_clusters in MachineClass is not a user configured
field, and it indicates if user specifies "clusters" in -smp.

After -smp parsing, other module could aware if the cluster level
is configured by user. This is used when the machine has only 1 cluster
since there's only 1 cluster by default.

Add the check to cover this field.

ef88e1e875 tests/unit/test-smp-parse: Test the full 7-levels topology hierarchy
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.

4c1608caa4 tests/libqos: add riscv/virt machine nodes
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.

13ddcf0a7a tests: bump QOS_PATH_MAX_ELEMENT_SIZE again
We "fixed" a bug with LTO builds with 100c459f19 (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.

We use section "Returns" for documenting both success and error
response of commands.

I intend to generate better command success response documentation.
Easier when "Returns" documents just he success response.

Create new section tag "Errors".  The next two commits will move error
response documentation from "Returns" sections to "Errors" sections.

3283843a8e libqos/virtio.c: fix 'avail_event' offset in qvring_init()
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.

2791490de1 libqos/virtio.c: init all elems in qvring_indirect_desc_setup()
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().

151b7dba39 tests/vm: avoid re-building the VM images all the time
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.

542b10bd14 tests/tcg: update licenses to GPLv2 as intended
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.

adb0193b90 qapi: Divorce QAPIDoc from QAPIParseError
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.
