Since the process is using exec in the subshell, the PID is the

track the qemu PID, however, if requested - not all usage requires

We have several tests that perform multiple sub-actions that are
expected to fail. Asserting that an error occurred, then clearing
it up to prepare for the next action, turned into enough
boilerplate that it was sometimes forgotten (for example, a number
of tests added to test-qmp-input-visitor.c in d88f5fd leaked err).
Worse, if an error is not reset to NULL, we risk invalidating
later use of that error (passing a non-NULL err into a function
is generally a bad idea). Encapsulate the boilerplate into a
single helper function error_free_or_abort(), and consistently
use it.
The new function is added into error.c for use everywhere,
although it is anticipated that testsuites will be the main

By using &error_abort, we can avoid a local err variable in
situations where we expect success. It also has the nice
effect that if the test breaks, the error message from
error_abort tends to be nicer than that of g_assert().
This patch has an additional bonus of fixing several call sites that
were passing &err to two different functions without checking it in
between. In general that is unsafe practice; because if the first
function sets an error, the second function could abort() if it tries to
set a different error. We got away with it because we were asserting
that err was NULL through the entire chain, but switching to
&error_abort avoids the questionable practice up front.

Make valgrind happy with the current state of the tests, so that
it is easier to see if future patches introduce new memory problems
without being drowned in noise. Many of the leaks were due to
calling a second init without tearing down the data from an earlier
visit. But since teardown is already idempotent, and we already
register teardown as part of input_visitor_test_add(), it is nicer
to just make init() safe to call multiple times than it is to have
to make all tests call teardown.
Another common leak was forgetting to clean up an error object,
after testing that an error was raised.
Another leak was in test_visitor_in_struct_nested(), failing to
clean the base member of UserDefTwo. Cleaning that up left
check_and_free_str() as dead code (since using the qapi_free_*
takes care of recursion, and we don't want double frees).
A final leak was in test_visitor_out_any(), which was reassigning
the qobj local variable to a subset of the overall structure
needing freeing; it did not result in a use-after-free, but
was not cleaning up all the qdict.
test-qmp-event and test-qmp-commands were already clean.

Commit d88f5fd and friends first introduced the various test-qmp-*
tests in 2011, with duplicated hand-rolled TestStruct machinery,
to make sure the qapi visitor interface was tested. Later, commit
4f193e3 in 2013 added a .json file for further testing use by the
files, but without consolidating any of the existing hand-rolled
visitors. And with four copies, subtle differences have crept in,
between the tests themselves (mainly whitespace differences, but
also a question of whether to use NULL or "TestStruct" when
calling visit_start_struct()) and from what the generator produces
(the hand-rolled versions did not cater to partially-allocated
objects, because they did not have a deallocation usage).
Of course, just because the visitor interface is tested does not
mean it is a sane interface; and future patches will be changing
some of the visitor contracts. Rather than having to duplicate
the cleanup work in each copy of the TestStruct visitor, and keep
each hand-rolled copy in sync with what the generator supplies, we
might as well just test what the generator should give us in the
first place.

Now that we have separated union tag values from colliding with
non-variant C names, by naming the union 'u', we should reserve
this name for our use. Note that we want to forbid 'u' even in
a struct with no variants, because it is possible for a future
qemu release to extend QMP in a backwards-compatible manner while
converting from a struct to a flat union. Fortunately, no
existing clients were using this member name. If we ever find
the need for QMP to have a member 'u', we could at that time
relax things, perhaps by having c_name() munge the QMP member to
'q_u'.
Note that we cannot forbid 'u' everywhere (by adding the
rejection code to check_name()), because the existing QKeyCode
enum already uses it; therefore we only reserve it as a struct
type member name.

We have two issues with our qapi union layout:
1) Even though the QMP wire format spells the tag 'type', the
C code spells it 'kind', requiring some hacks in the generator.
2) The C struct uses an anonymous union, which places all tag
values in the same namespace as all non-variant members. This
leads to spurious collisions if a tag value matches a non-variant
member's name.

Rather than storing a base class as a pointer to a box, just
store the fields of that base class in the same order, so that
a child struct can be directly cast to its parent. This gives
less malloc overhead, less pointer dereferencing, and even less
generated code. Compare to the earlier commit 1e6c1616a "qapi:
Generate a nicer struct for flat unions" (although that patch
had fewer places to change, as less of qemu was directly using
qapi structs for flat unions). It also allows us to turn on
automatic type-safe wrappers for upcasting to the base class
of a struct.
Changes to the generated code look like this in qapi-types.h:
| struct SpiceChannel {
|- SpiceBasicInfo *base;
|+ /* Members inherited from SpiceBasicInfo: */
|+ char *host;
|+ char *port;
|+ NetworkAddressFamily family;
|+ /* Own members: */
| int64_t connection_id;
as well as additional upcast functions like qapi_SpiceChannel_base().
Meanwhile, changes to qapi-visit.c look like:
| static void visit_type_SpiceChannel_fields(Visitor *v, SpiceChannel **obj, Error **errp)
| {
| Error *err = NULL;
|
|- visit_type_implicit_SpiceBasicInfo(v, &(*obj)->base, &err);
|+ visit_type_SpiceBasicInfo_fields(v, (SpiceBasicInfo **)obj, &err);
| if (err) {
(the cast is necessary, since our upcast wrappers only deal with a
single pointer, not pointer-to-pointer); plus the wholesale
elimination of some now-unused visit_type_implicit_FOO() functions.
Without boxing, the corner case of one empty struct having
another empty struct as its base type now requires inserting a
dummy member (previously, the 'Base *base' member sufficed).
And now that we no longer consume a 'base' member in the generated
C struct, we can delete the former negative struct-base-clash-base
test.

A previous patch (commit 1e6c1616) made it possible to
directly cast from a qapi flat union type to its base type.
However, it requires the use of a C cast, which turns off
compiler type-safety checks. Fortunately, no such casts
exist, just yet.
Regardless, add inline type-safe wrappers named
qapi_FOO_base() for any union type FOO that has a base,
which can be used for a safer upcast, and enhance the
testsuite to cover the new functionality.
A future patch will extend the upcast support to structs,
where such conversions do exist already.
Note that C makes const-correct upcasts annoying because
it lacks overloads; these functions cast away const so that
they can accept user pointers whether const or not, and the
result in turn can be assigned to normal or const pointers.
Alternatively, this could have been done with macros, but
type-safe macros are hairy, and not worthwhile here.
This patch just adds upcasts. None of our code needed to
downcast from a base qapi class to a child. Also, in the
case of grandchildren (such as BlockdevOptionsQcow2), the
caller will need to call two functions to get to the inner
base (although it wouldn't be too hard to generate a
qapi_FOO_base_base() if desired). If a user changes qapi
to alter the base class hierarchy, such as going from
'A -> C' to 'A -> B -> C', it will change the type of
'qapi_C_base()', and the compiler will point out the places
that are affected by the new base.
One alternative was proposed, but was deemed too ugly to use
in practice: the generators could output redundant
information using anonymous types:
| struct Child {
| union {
| struct {
| Type1 parent_member1;
| Type2 parent_member2;
| };
| Parent base;
| };
| };
With that ugly proposal, for a given qapi type, obj->member
and obj->base.member would refer to the same storage; allowing
convenience in working with members without needing 'base.'
allowing typesafe upcast without needing a C cast by accessing
'&obj->base', and allowing downcasts from the parent back to
the child possible through container_of(obj, Child, base).

c_name() produces names starting with 'q_' when protecting a
dictionary member name that would fail to directly compile, but
in doing so can cause clashes with any member name already
beginning with 'q-' or 'q_'. Likewise, we create a C name 'has_'
for any optional member that can clash with any member name
beginning with 'has-' or 'has_'.
Technically, rather than blindly reserving the namespace,
we could try to complain about user names only when an actual
collision occurs, or even teach c_name() how to munge names
to avoid collisions. But it is not trivial, especially when
collisions can occur across multiple types (such as via
inheritance or flat unions). Besides, no existing .json
files are trying to use these names. So it's easier to just
outright forbid the potential for collision. We can always
relax things in the future if a real need arises for QMP to
express member names that have been forbidden here.
'has_' only has to be reserved for struct/union member names,
while 'q_' is reserved everywhere (matching the fact that
only members can be optional, while we use c_name() for munging
both members and entities). Note that we could relax 'q_'
restrictions on entities independently from member names; for
example, c_name('qmp_' + 'unix') would result in a different
function name than our current 'qmp_' + c_name('unix').

Add some testsuite coverage to ensure future patches are on
the right track:
Our current C representation of qapi arrays is done by appending
'List' to the element name; but we are not preventing the
creation of an object type with the same name. Add
reserved-type-list.json to test this. Then rename
enum-union-clash.json to reserved-type-kind.json to cover the
reservation that we DO detect, and shorten it to match the fact
that the name is reserved even if there is no clash.
We are failing to detect a collision between a dictionary member
and the implicit 'has_*' flag for another optional member. The
easiest fix would be for a future patch to reserve the entire
"has[-_]" namespace for member names (the collision is also
possible for branch names within flat unions, but only as long as
branch names can collide with (non-variant) members; however,
since future patches are about to remove that, it is not worth
testing here). Add reserved-member-has.json to test this.
A similar collision exists between a dictionary member where
c_name() munges what might otherwise be a reserved name to start
with 'q_', and another member explicitly starts with "q[-_]".
Again, the easiest solution for a future patch will be reserving
the entire namespace, but here for commands as well as members.
Add reserved-member-q.json and reserved-command-q.json to test
this; separate tests since arguably our munging of command 'unix'
to 'qmp_q_unix()' could be done without a q_, which is different
than the munging of a member 'unix' to 'foo.q_unix'.
Finally, our testsuite does not have any compilation coverage
of struct inheritance with empty qapi structs. Update
qapi-schema-test.json to test this.
Note that there is currently no technical reason to forbid type
name patterns from member names, or member name patterns from
types, since the two are not in the same namespace in C and
won't collide; but it's not worth adding positive tests of these
corner cases at this time, especially while there is other churn
pending in patches that rearrange which collisions actually
happen.

The test existing in QEMU for vhost-user feature is good for
testing the management protocol, but does not allow actual
traffic. This patch proposes Vhost-User Bridge application, which
can serve the QEMU community as a comprehensive test by running
real internet traffic by means of vhost-user interface.
Essentially the Vhost-User Bridge is a very basic vhost-user
backend for QEMU. It runs as a standalone user-level process.
For packet processing Vhost-User Bridge uses an additional QEMU
instance with a backend configured by "-net socket" as a shared
VLAN. This way another QEMU virtual machine can effectively
serve as a shared bus by means of UDP communication.
For a more simple setup, the another QEMU instance running the
SLiRP backend can be the same QEMU instance running vhost-user
client.
This Vhost-User Bridge implementation is very preliminary. It is
missing many features. I has been studying vhost-user protocol
internals, so I've written vhost-user-bridge bit by bit as I
progressed through the protocol. Most probably its internal
architecture will change significantly.
To run Vhost-User Bridge application:
1. Build vhost-user-bridge with a regular procedure. This will
create a vhost-user-bridge executable under tests directory:
$ configure; make tests/vhost-user-bridge
2. Ensure the machine has hugepages enabled in kernel with
command line like:
default_hugepagesz=2M hugepagesz=2M hugepages=2048
3. Run Vhost-User Bridge with:
$ tests/vhost-user-bridge
The above will run vhost-user server listening for connections
on UNIX domain socket /tmp/vubr.sock, and will try to connect
by UDP to VLAN bridge to localhost:5555, while listening on
localhost:4444
Run qemu with a virtio-net backed by vhost-user:
$ qemu \
-enable-kvm -m 512 -smp 2 \
-object memory-backend-file,id=mem,size=512M,mem-path=/dev/hugepages,share=on \
-numa node,memdev=mem -mem-prealloc \
-chardev socket,id=char0,path=/tmp/vubr.sock \
-netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce \
-device virtio-net-pci,netdev=mynet1 \
-net none \
-net socket,vlan=0,udp=localhost:4444,localaddr=localhost:5555 \
-net user,vlan=0 \
disk.img
vhost-user-bridge was tested very lightly: it's able to bringup a
linux on client VM with the virtio-net driver, and execute transmits
and receives to the internet. I tested with "wget redhat.com",
"dig redhat.com".
PS. I've consulted DPDK's code for vhost-user during Vhost-User
Bridge implementation.

- pair of instances, check memory sharing
- pair of instances with server, and MSIX
- hot plug/unplug
A temporary shm is created as well as a directory to place server
socket, both should be clear on exit and abort.

However, if "id" is missing, "node-name" must be specified; otherwise,

QGA skips pseudo-filesystems when querying filesystems via
guest-get-fsinfo. On some hosts, such as travis-ci which uses
containers with simfs filesystems, QGA might not report *any*
filesystems. Our test case assumes there would be at least one,
leading to false error messages in these situations.
Instead, sanity-check values iff we get at least one filesystem.

Author: Daniel P. Berrange <berrange@redhat.com>
Date: Mon Apr 13 14:01:39 2015 +0100
crypto: add sanity checking of TLS x509 credentials
defined new variables $TEST_LIBS and $TEST_CFLAGS and
used them in tests/Makefile to augment $LIBS and $CFLAGS.
Unfortunately this overlooks the fact that tests/Makefile
is not executed via recursive-make, it is just pulled into
the top level Makefile via an include statement. So rather
than just augmenting the compiler/linker flags for tests
it polluted the global flags.
This is thought to be behind a reported failure when
building the pixman module as a sub-module, since global
$CFLAGS are passed down to configure in pixman.
This change removes the $TEST_LIBS and $TEST_CFLAGS
replacing them with $TASN1_LIBS and $TASN1_CFLAGS,
setting only against specific objects/executables
that need them.

The coroutine files are currently referenced by the block-obj-y
variable. The coroutine functionality though is already used by
more than just the block code. eg migration code uses coroutine
yield. In the future the I/O channel code will also use the
coroutine yield functionality. Since the coroutine code is nicely
self-contained it can be easily built as part of the libqemuutil.a
library, making it widely available.
The headers are also moved into include/qemu, instead of the
include/block directory, since they are now part of the util
codebase, and the impl was never in the block/ directory

[PMM: Added change to tests/ds1338-test.c to use new machine name]
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
Commit ac88219a had several TODO markers about whether we needed
to automatically create the corresponding array type alongside
any other type. It turns out that most of the time, we don't!
There are a few exceptions: 1) We have a few situations where we
use an array type in internal code but do not expose that type
through QMP; fix it by declaring a dummy type that forces the
generator to see that we want to use the array type.
2) The builtin arrays (such as intList for QAPI ['int']) must
always be generated, because of the way our QAPI_TYPES_BUILTIN
compile guard works: we have situations (at the very least
tests/test-qmp-output-visitor.c) that include both top-level
"qapi-types.h" (via "error.h") and a secondary
"test-qapi-types.h". If we were to only emit the builtin types
when used locally, then the first .h file would not include all
types, but the second .h does not declare anything at all because
the first .h set QAPI_TYPES_BUILTIN, and we would end up with
compilation error due to things like unknown type 'int8List'.
Actually, we may need to revisit how we do type guards, and
change from a single QAPI_TYPES_BUILTIN over to a different
usage pattern that does one #ifdef per qapi type - right now,
the only types that are declared multiple times between two qapi
.json files for inclusion by a single .c file happen to be the
builtin arrays. But now that we have QAPI 'include' statements,
it is logical to assume that we will soon reach a point where
we want to reuse non-builtin types (yes, I'm thinking about what
it will take to add introspection to QGA, where we will want to
reuse the SchemaInfo type and friends). One #ifdef per type
will help ensure that generating the same qapi type into more
than one qapi-types.h won't cause collisions when both are
included in the same .c file; but we also have to solve how to
avoid creating duplicate qapi-types.c entry points. So that
is a problem left for another day.
Generated code for qapi-types and qapi-visit is drastically
reduced; less than a third of the arrays that were blindly
created were actually needed (a quick grep shows we dropped
from 219 to 69 *List types), and the .o files lost more than
30% of their bulk. [For best results, diff the generated
files with 'git diff --patience --no-index pre post'.]
Interestingly, the introspection output is unchanged - this is
because we already cull all types that are not indirectly
reachable from a command or event, so introspection was already
using only a subset of array types. The subset of types
introspected is now a much larger percentage of the overall set
of array types emitted in qapi-types.h (since the larger set
shrunk), but still not 100% (evidence that the array types
emitted for our new Dummy structs, and the new struct itself,
don't affect QMP).

Rather than open-code the check for a valid base type, we
should reuse the common functionality. This allows for
consistent error messages, and also makes it easier for a
later patch to turn on support for inline anonymous base
structures.
Test flat-union-inline is updated to test only one feature
(anonymous branch dictionaries), which can be implemented
independently (test flat-union-bad-base already covers the
idea of an anonymous base dictionary).

Add some testsuite exposure for use of a 'number' as part of
an alternate. The current state of the tree has a few bugs
exposed by this: our input parser depends on the ordering of
how the qapi schema declared the alternate, and the parser
does not accept integers for a 'number' in an alternate even
though it does for numbers outside of an alternate.
Mixing 'int' and 'number' in the same alternate is unusual,
since both are supplied by json-numbers, but there does not
seem to be a technical reason to forbid it given that our
json lexer distinguishes between json-numbers that can be
represented as an int vs. those that cannot.
Improve the existing test_visitor_in_alternate() to match the
style of the new test_visitor_in_alternate_number(), and to
ensure full coverage of all possible qtype parsing.

[Eric's follow-up fixes squashed in]
Signed-off-by: Markus Armbruster <armbru@redhat.com>
The documentation claims that alternates are useful for
allowing two or more types, although nothing enforces this.
Meanwhile, it is silent on whether empty unions are allowed.
In practice, the generated code will compile, in part because
we have a 'void *data' branch; but attempting to visit such a
type will cause an abort(). While there's no technical reason
that a degenerate union could not be made to work, it's harder
to justify the time spent in chasing known (the current
abort() during visit) and unknown corner cases, than it would
be to just outlaw them. A future patch will probably take the
approach of forbidding them; in the meantime, we can at least
add testsuite coverage to make it obvious where things stand.
In addition to adding tests to expose the problems, we also
need to adjust existing tests that are meant to test something
else, but which could fail for the wrong reason if we reject
degenerate alternates/unions.
Note that empty structs are explicitly supported (for example,
right now they are the only way to specify that one branch of a
flat union adds no additional members), and empty enums are
covered by the testsuite as working (even if they do not seem
to have much use).

The previous commit added two tests that triggered an assertion
failure. It's fairly straightforward to avoid the failure by
just outright forbidding the collision between a union's tag
values and its discriminator name (including the implicit name
'kind' supplied for simple unions [*]). Ultimately, we'd like
to move the collision detection into QAPISchema*.check(), but
for now it is easier just to enhance the existing checks.
[*] Of course, down the road, we have plans to rename the simple
union tag name to 'type' to match the QMP wire name, but the
idea of the collision will still be present even then.
Technically, we could avoid the collision by naming the C union
members representing each enum value as '_case_value' rather
than 'value'; but until we have an actual qapi client (and not
just our testsuite) that has a legitimate reason to match a
case label to the name of a QMP key and needs the name munging
to satisfy the compiler, it's easier to just reject the qapi
as invalid.

Expose some weaknesses in the generator: we don't always forbid
the generation of structs that contain multiple members that map
to the same C or QMP name. This has already been marked FIXME in
qapi.py in commit d90675f, but having more tests will make sure
future patches produce desired behavior; and updating existing
patches to better document things doesn't hurt, either. Some of
these collisions are already caught in the old-style parser
checks, but ultimately we want all collisions to be caught in the
new-style QAPISchema*.check() methods.
This patch focuses on C struct members, and does not consider
collisions between commands and events (affecting C function
names), or even collisions between generated C type names with
user type names (for things like automatic FOOList struct
representing array types or FOOKind for an implicit enum).
There are two types of struct collisions we want to catch:
1) Collision between two keys in a JSON object. qapi.py prevents
that within a single struct (see test duplicate-key), but it is
possible to have collisions between a type's members and its
base type's members (existing tests struct-base-clash,
struct-base-clash-deep), and its flat union variant members
(renamed test flat-union-clash-member).
2) Collision between two members of the C struct that is generated
for a given QAPI type:
a) Multiple QAPI names map to the same C name (new test
args-name-clash)
b) A QAPI name maps to a C name that is used for another purpose
(new tests flat-union-clash-branch, struct-base-clash-base,
union-clash-data). We already fixed some such cases in commit
0f61af3e and 1e6c1616, but more remain.
c) Two C names generated for other purposes clash
(updated test alternate-clash, new test union-clash-branches,
union-clash-type, flat-union-clash-type)
Ultimately, if we need to have a flat union where a tag value
clashes with a base member name, we could change the generator to
name the union (using 'foo.u.value' rather than 'foo.value') or
otherwise munge the C name corresponding to tag values. But
unless such a need arises, it will probably be easier to just
forbid these collisions.
Some of these negative tests will be deleted later, and positive
tests added to qapi-schema-test.json in their place, when the
generator code is reworked to avoid particular code generation
collisions in class 2).
[Note that viewing this patch with git rename detection enabled
may see some confusion due to renaming some tests while adding
others, but where the content is similar enough that git picks
the wrong pre- and post-patch files to associate]

Recent changes to qapi have provided quite a bit of churn in
the makefile, because we are inconsistent on what order test
names appear in, and on whether to re-wrap the list of tests or
just add arbitrary line lengths. Writing the list in a sorted
fashion, one test per line, will make future patches easier
to see what tests are being added or removed by a patch.
Although it is tempting to use $(wildcard qapi-schema/*.json)
for a more compact listing, such an approach would risk picking
up leftover garbage .json files in the directory; so keeping
the list explicit is safer for ensuring reproducible tarballs
and test results.

Several devices don't survive object_unref(object_new(T)): they crash
or hang during cleanup, or they leave dangling pointers behind.
This breaks at least device-list-properties, because
qmp_device_list_properties() needs to create a device to find its
properties. Broken in commit f4eb32b "qmp: show QOM properties in
device-list-properties", v2.1. Example reproducer:
$ qemu-system-aarch64 -nodefaults -display none -machine none -S -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 50, "minor": 4, "major": 2}, "package": ""}, "capabilities": []}}
{ "execute": "qmp_capabilities" }
{"return": {}}
{ "execute": "device-list-properties", "arguments": { "typename": "pxa2xx-pcmcia" } }
qemu-system-aarch64: /home/armbru/work/qemu/memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed.
Aborted (core dumped)
[Exit 134 (SIGABRT)]
Unfortunately, I can't fix the problems in these devices right now.
Instead, add DeviceClass member cannot_destroy_with_object_finalize_yet
to mark them:
* Hang during cleanup (didn't debug, so I can't say why):
"realview_pci", "versatile_pci".
* Dangling pointer in cpus: most CPUs, plus "allwinner-a10", "digic",
"fsl,imx25", "fsl,imx31", "xlnx,zynqmp", because they create such
CPUs
* Assert kvm_enabled(): "host-x86_64-cpu", host-i386-cpu",
"host-powerpc64-cpu", "host-embedded-powerpc-cpu",
"host-powerpc-cpu" (the powerpc ones can't currently reach the
assertion, because the CPUs are only registered when KVM is enabled,
but the assertion is arguably in the wrong place all the same)
Make qmp_device_list_properties() fail cleanly when the device is so
marked. This improves device-list-properties from "crashes, hangs or
leaves dangling pointers behind" to "fails". Not a complete fix, just
a better-than-nothing work-around. In the above reproducer,
device-list-properties now fails with "Can't list properties of device
'pxa2xx-pcmcia'".
This also protects -device FOO,help, which uses the same machinery
since commit ef52358 "qdev-monitor: include QOM properties in -device
FOO, help output", v2.2. Example reproducer:
$ qemu-system-aarch64 -machine none -device pxa2xx-pcmcia,help

We want to run qom-test for every architecture, without having to
manually add it to every architecture's list of tests. Commit 3687d53
accomplished this by adding it to every architecture's list
automatically.
However, some architectures inherit their tests from others, like this:
check-qtest-x86_64-y = $(check-qtest-i386-y)
check-qtest-microblazeel-y = $(check-qtest-microblaze-y)
check-qtest-xtensaeb-y = $(check-qtest-xtensa-y)
For such architectures, we ended up running the (slow!) test twice.
Commit 2b8419c attempted to avoid this by adding the test only when
it's not already present. Works only as long as we consider adding
the test to the architectures on the left hand side *after* the ones
on the right hand side: x86_64 after i386, microblazeel after
microblaze, xtensaeb after xtensa.
Turns out we consider them in $(SYSEMU_TARGET_LIST) order. Defined as
SYSEMU_TARGET_LIST := $(subst -softmmu.mak,,$(notdir \
$(wildcard $(SRC_PATH)/default-configs/*-softmmu.mak)))
On my machine, this results in the oder xtensa, x86_64, microblazeel,
microblaze, i386. Consequently, qom-test runs twice for microblazeel
and x86_64.
Replace this complex and flawed machinery with a much simpler one: add
generic tests (currently just qom-test) to check-qtest-generic-y
instead of check-qtest-$(target)-y for every target, then run
$(check-qtest-generic-y) for every target.
