There is no reason for CONFIG_VHOST_NET to be specific to a single target;
it is a host feature that can be add to all targets, as long as they support
the virtio-net device. Currently CONFIG_VHOST_NET depends on CONFIG_KVM,
but ioeventfd support is present in the core memory API and works with
other accelerators as well.
As a first step, move the vhost-net stubs to a separate file. Later, they
will become conditional on CONFIG_VIRTIO_NET, which is not available in .c
files.

According to "git blame", most of the stubs line have been added after
January in 2012, so if Michael agrees for the remaining lines, you could
maybe use a proper GPLv2+ text only for this file instead of the
confusing "dual" licensing?
Anyway,

hw/net/vhost_net.c needs functions that are declared in net/vhost-user.c: the
vhost-user code is always compiled into QEMU, only the constructor
net_init_vhost_user is unreachable. Also, net/vhost-user.c needs functions
declared in hw/virtio/vhost-stub.c even if no virtio device exists.
Break this dependency. First, add a minimal version of net/vhost-user.c,
with no functionality and no dependency on vhost code. Second, #ifdef out
the calls back to net/vhost-user.c from hw/net/vhost_net.c.

It's a little bit sad that we need the stub in this case, but since
CONFIG_VIRTIO_NET is not available as a CPP macro, I also don't have any
better ideas.

vhost-user does not depend on Linux; it can run on any POSIX system. Restrict
vhost-kernel to Linux in hw/virtio/vhost-backend.c, everything else can be
compiled on all POSIX systems.

This shows a preexisting bug: if a KVM target did not have virtio-net enabled,
it would fail with undefined symbols when vhost was enabled. This must now
be fixed, lest targets that have no virtio-net fail to compile.

Detect all invalid configurations (e.g. mingw32 with vhost-user,
non-Linux with vhost-kernel). As a collateral benefit, all vhost-kernel
backends can be now disabled if one wants to reduce the attack surface.

g_cond_signal is rarely the right thing to do, it works now because
vhost-user-test only has two threads but it is not correct in general.
Fix it before adding more calls.

This speeds up wait_for_rings_started, which currently is just waiting for
the timeout before checking s->rings.

vhost-user already has a way to communicate the endianness of the guest
via the vring endianness messages. The vring endianness always matches
the vnet header endianness so there is no need to do anything else in
the backend.

Can't you simply use memread() intead?

Yes, I guess I could do memread + memcmp, but I wanted to change the
code as little as possible here.

The virt machine cannot run the vhost-user qtests because they hardcode
the presence of memory at address 0. Report the tests as a skip so that
they can be converted to use qgraph.

g_test_skip does not work with older versions of the gtester ... so this
patch series depends on your gtester replacement patches first?

Whenever the code can run on multiple QTestStates, use them explicitly instead of
global_qtest.

Looks like it should work. Maybe you could use this patch here first:
https://lists.gnu.org/archive/html/qemu-devel/2018-11/msg02199.html
... then you could likely get rid of global_qtest here completely, I think.
Anyway:

Note that most of the global_qtest references disappear with the qgraph
conversion. Each qgraph object already knows which QTestState it refers
to. However there are a couple that remain, I'll check if there's
anything to improve in the QOSGraphObject APIs to remove them.

This makes the tests more independent and removes the need to defer test_server_free
via an idle event source.

After the conversion to qgraph, the equivalent of "main" will be in
a constructor and will run even if the tests are not being requested.
Therefore, it should not assert that init_hugepagefs succeeds and will
be called when creating the TestServer. This patch changes the prototype
of init_hugepagefs, this way the next patch looks nicer.

TestServers in the migration test.

Rename qpci_init_pc in qpci_pc_new and qpci_init_spapr in qpci_spapr_new,
since theese function actually allocate a new pci struct and initialize it.
Changed QOSOps field name from qpci_init to qpci_new.

Matter of taste, I guess ... I'd also be fine if we keep "init" instead

qgraph will embed these objects instead of allocating them in a separate
object. Expose a new API "generic_alloc_init" and "generic_alloc_destroy"
for that, and rename the existing API with s/init/new/ and s/uninit/free/.

The explanation is simply that if you allocate them separately you have
to define a destructor function to free it---more boilerplate and more
stuff that you can get wrong. Therefore qgraph tries to use embedded
structs when something is always there (a "contains" edge).
The same is true for 16/71, you want to use heap-allocated PCI buses for
non-qgraph tests, but for a qgraph machine it would be very much
preferrable to embed it in the PCI host bridge QOSGraphObject.

From: Emanuele Giuseppe Esposito <e.emanuelegiuseppe@gmail.com>
Add qgraph API that allows to add/remove nodes and edges from the graph,
implementation of Depth First Search to discover the paths and basic unit
test to check correctness of the API.
Included also a main executable that takes care of starting the framework,
create the nodes, set the available drivers/machines, discover the path and
run tests.
graph.h provides the public API to manage the graph nodes/edges
graph_extra.h provides a more private API used successively by the gtest integration part
qos-test.c provides the main executable
Signed-off-by: Emanuele Giuseppe Esposito <e.emanuelegiuseppe@gmail.com>
[Paolo's changes compared to the Google Summer of Code submission:
* added subprocess to test options
* refactored object creation to support live migration tests
* removed driver .before callback (unused)
* removed test .after callbacks (replaced by GTest destruction queue)]

+ * SECTION: qgraph.h
+ * @title: Qtest Driver Framework
+ * @short_description: interfaces to organize drivers and tests
+ * as nodes in a graph
+ *
+ * This Qgraph API provides all basic functions to create a graph
+ * and instantiate nodes representing machines, drivers and tests
+ * representing their relations with CONSUMES, PRODUCES, and CONTAINS
+ * edges.
+ *
+ * The idea is to have a framework where each test asks for a specific
+ * driver, and the framework takes care of allocating the proper devices
+ * required and passing the correct command line arguments to QEMU.
+ *
+ * A node can be of four types:
+ * - QNODE_MACHINE: for example "arm/raspi2"
+ * - QNODE_DRIVER: for example "generic-sdhci"
+ * - QNODE_INTERFACE: for example "sdhci" (interface for all "-sdhci" drivers)
+ * an interface is not explicitly created, it will be auto-
+ * matically instantiated when a node consumes or produces
+ * it.
+ * - QNODE_TEST: for example "sdhci-test", consumes an interface and tests
+ * the functions provided
+ *
+ * Notes for the nodes:
+ * - QNODE_MACHINE: each machine struct must have a QGuestAllocator and
+ * implement get_driver to return the allocator passing
+ * "memory". The function can also return NULL if the
+ * allocator is not set.
+ * - QNODE_DRIVER: driver names must be unique, and machines and nodes
+ * planned to be "consumed" by other nodes must match QEMU
+ * drivers name, otherwise they won't be discovered
+ *
+ * An edge relation between two nodes (drivers or machines) X and Y can be:
+ * - X CONSUMES Y: Y can be plugged into X
+ * - X PRODUCES Y: X provides the interface Y
+ * - X CONTAINS Y: Y is part of X component
+ *
+ * Basic framework steps are the following:
+ * - All nodes and edges are created in their respective
+ * machine/driver/test files
+ * - The framework starts QEMU and asks for a list of available devices
+ * and machines (note that only machines and "consumed" nodes are mapped
+ * 1:1 with QEMU devices)
+ * - The framework walks the graph starting from the available machines and
+ * performs a Depth First Search for tests
+ * - Once a test is found, the path is walked again and all drivers are
+ * allocated accordingly and the final interface is passed to the test
+ * - The test is executed
+ * - Unused objects are cleaned and the path discovery is continued
+ *
+ * Depending on the QEMU binary used, only some drivers/machines will be
+ * available and only test that are reached by them will be executed.

+ *
+ * </programlisting>
+ * </example>
+ *
+ * Here a new test is created, consuming "my_interface" node
+ * and creating a valid path from a machine to a test.
+ * Final graph will be like this:
+ * x86_64/pc -->contains--> other_node <--consumes-- my_driver
+ * |
+ * my_driver_contained <--contains--+
+ * |
+ * my_test --consumes--> my_interface <--produces--+

+ * |
+ * my_driver_contained <--contains--+
+ * |
+ * my_test <--consumed_by-- my_interface <--produces--+
+ *
+ * Assuming there the binary is
+ * QTEST_QEMU_BINARY=x86_64-softmmu/qemu-system-x86_64
+ * a valid test path will be:
+ * "/x86_64/pc/other_node/my_driver/my_interface/my_test".
+ *
+ * Additional examples are also in libqos/test-qgraph.c
+ *
+ * Command line:
+ * Command line is built by using node names and optional arguments
+ * passed by the user when building the edges.
+ *
+ * There are three types of command line arguments:
+ * - in node : created from the node name. For example, machines will
+ * have "-M <machine>" to its command line, while devices
+ * "- device <device>". It is automatically done by the
+ * framework.
+ * - after node : added as additional argument to the node name.
+ * This argument is added optionally when creating edges,
+ * by setting the parameter @after_cmd_line and
+ * @extra_edge_opts in #QOSGraphEdgeOptions.
+ * The framework automatically adds
+ * a comma before @extra_edge_opts,
+ * because it is going to add attibutes
+ * after the destination node pointed by
+ * the edge containing these options, and automatically
+ * adds a space before @after_cmd_line, because it
+ * adds an additional device, not an attribute.
+ * - before node : added as additional argument to the node name.
+ * This argument is added optionally when creating edges,
+ * by setting the parameter @before_cmd_line in
+ * #QOSGraphEdgeOptions. This attribute
+ * is going to add attibutes before the destination node
+ * pointed by the edge containing these options. It is
+ * helpful to commands that are not node-representable,
+ * such as "-fdsev" or "-netdev".
+ *
+ * While adding command line in edges is always used, not all nodes names are
+ * used in every path walk: this is because the contained or produced ones
+ * are already added by QEMU, so only nodes that "consumes" will be used to
+ * build the command line. Also, nodes that will have { "abstract" : true }
+ * as QMP attribute will loose their command line, since they are not proper
+ * devices to be added in QEMU.
+ *
+ * Example:
+ *
+ QOSGraphEdgeOptions opts = {
+ .arg = NULL,
+ .size_arg = 0,
+ .after_cmd_line = "-device other",
+ .before_cmd_line = "-netdev something",
+ .extra_edge_opts = "addr=04.0",
+ };
+ QOSGraphNode * node = qos_node_create_driver("my_node", constructor);
+ qos_node_consumes_args("my_node", "interface", &opts);
+ *
+ * Will produce the following command line:
+ * "-netdev something -device my_node,addr=04.0 -device other"

+ * nodes, using the provided constructor. To satisfy their relations,
+ * i.e. for produces or contains, where a struct constructor needs
+ * an external parameter represented by the previous node,
+ * the framework will call get_device (for contains) or
+ * get_driver (for produces), depending on the edge type, passing
+ * them the name of the next node to be taken and getting from them
+ * the corresponding pointer to the actual structure of the next node to
+ * be used in the path.
+ *
+ * - start_hw: This function is executed after all the path objects
+ * have been allocated, but before the test is run. It starts the hw, setting
+ * the initial configurations (*_device_enable) and making it ready for the
+ * test.
+ *
+ * - destructor: Opposite to the node constructor, destroys the object.
+ * This function is called after the test has been executed, and performs
+ * a complete cleanup of each node allocated field. In case no constuctor
+ * is provided, no destructor will be called.

The license statement is inaccurate. There is no "GNU *Lesser* General
Public License version *2*" ... so I'm assuming you wanted to use one of
these two options:
- GNU Library General Public License, version 2.0
- GNU Lesser General Public License, version 2.1
I assume you wanted to use the latter, so please replace the "2" with
"2.1" in all license statements here.

Yes, I will change it to Lesser GPL 2.1.

> + * SECTION: qgraph.h
> + * @title: Qtest Driver Framework
> + * @short_description: interfaces to organize drivers and tests
> + * as nodes in a graph
> + *
> + * This Qgraph API provides all basic functions to create a graph
> + * and instantiate nodes representing machines, drivers and tests
> + * representing their relations with CONSUMES, PRODUCES, and CONTAINS
> + * edges.
> + *
> + * The idea is to have a framework where each test asks for a specific
> + * driver, and the framework takes care of allocating the proper devices
> + * required and passing the correct command line arguments to QEMU.
> + *
> + * A node can be of four types:
> + * - QNODE_MACHINE: for example "arm/raspi2"
> + * - QNODE_DRIVER: for example "generic-sdhci"
> + * - QNODE_INTERFACE: for example "sdhci" (interface for all "-sdhci" drivers)
> + * an interface is not explicitly created, it will be auto-
> + * matically instantiated when a node consumes or produces
> + * it.
> + * - QNODE_TEST: for example "sdhci-test", consumes an interface and tests
> + * the functions provided
> + *
> + * Notes for the nodes:
> + * - QNODE_MACHINE: each machine struct must have a QGuestAllocator and
> + * implement get_driver to return the allocator passing
> + * "memory". The function can also return NULL if the
> + * allocator is not set.
> + * - QNODE_DRIVER: driver names must be unique, and machines and nodes
> + * planned to be "consumed" by other nodes must match QEMU
> + * drivers name, otherwise they won't be discovered
> + *
> + * An edge relation between two nodes (drivers or machines) X and Y can be:
> + * - X CONSUMES Y: Y can be plugged into X
> + * - X PRODUCES Y: X provides the interface Y
> + * - X CONTAINS Y: Y is part of X component
> + *
> + * Basic framework steps are the following:
> + * - All nodes and edges are created in their respective
> + * machine/driver/test files
> + * - The framework starts QEMU and asks for a list of available devices
> + * and machines (note that only machines and "consumed" nodes are mapped
> + * 1:1 with QEMU devices)
> + * - The framework walks the graph starting from the available machines and
> + * performs a Depth First Search for tests
> + * - Once a test is found, the path is walked again and all drivers are
> + * allocated accordingly and the final interface is passed to the test
> + * - The test is executed
> + * - Unused objects are cleaned and the path discovery is continued
> + *
> + * Depending on the QEMU binary used, only some drivers/machines will be
> + * available and only test that are reached by them will be executed.

> + * Command line:
> + * Command line is built by using node names and optional arguments

> + *
> + * There are three types of command line arguments:
> + * - in node : created from the node name. For example, machines will
> + * have "-M <machine>" to its command line, while devices
> + * "- device <device>". It is automatically done by the
s/- device/-device/
> + * framework.
> + * - after node : added as additional argument to the node name.
> + * This argument is added optionally when creating edges,
> + * by setting the parameter @after_cmd_line and
> + * @extra_edge_opts in #QOSGraphEdgeOptions.
> + * The framework automatically adds
> + * a comma before @extra_edge_opts,
> + * because it is going to add attibutes
> + * after the destination node pointed by
> + * the edge containing these options, and automatically
> + * adds a space before @after_cmd_line, because it
> + * adds an additional device, not an attribute.
> + * - before node : added as additional argument to the node name.
> + * This argument is added optionally when creating edges,
> + * by setting the parameter @before_cmd_line in
> + * #QOSGraphEdgeOptions. This attribute
> + * is going to add attibutes before the destination node
> + * pointed by the edge containing these options. It is
> + * helpful to commands that are not node-representable,
> + * such as "-fdsev" or "-netdev".
> + *
> + * While adding command line in edges is always used, not all nodes names are
> + * used in every path walk: this is because the contained or produced ones
> + * are already added by QEMU, so only nodes that "consumes" will be used to
> + * build the command line. Also, nodes that will have { "abstract" : true }
> + * as QMP attribute will loose their command line, since they are not proper
> + * devices to be added in QEMU.
> + *
> + * Example:
> + *
> + QOSGraphEdgeOptions opts = {
> + .arg = NULL,
> + .size_arg = 0,
> + .after_cmd_line = "-device other",
> + .before_cmd_line = "-netdev something",
> + .extra_edge_opts = "addr=04.0",
> + };
> + QOSGraphNode * node = qos_node_create_driver("my_node", constructor);
> + qos_node_consumes_args("my_node", "interface", &opts);
> + *
> + * Will produce the following command line:

I did not do a very detailed review, but from a quick glance, this looks
quite good to me already (apart from the few minor issues that I've
mentioned above)

Good, if this is okay for you, my plan is the following:
- send patches 1-18 in my next pull request to Peter
- send patches 15-19 for review as v2, for inclusion in your qtest tree
- once that is done and the patches are included in your tree, send the
more "boring" patches 20-71 directly to you as a pull request, basically
the same as in this submission only with checkpatch fixed.
Thanks,
Paolo

Sounds like a plan, yes. (and yes, I still plan to review the remaining
patches, I just did not have enough spare time for that yet ...)

Add pci-bus-pc node, move QPCIBusPC struct declaration in its header
(since it will be needed by other drivers) and introduce a setter method
for drivers that do not need to allocate but have to initialize QPCIBusPC.

Add qgraph nodes for sdhci-pci and generic-sdhci (memory mapped) drivers.
Both drivers implement (produce) the same interface sdhci, that provides the
readw - readq - writeq functions.

Convert tests/sdhci-test in first qgraph test node, sdhci-test. This test
consumes an sdhci interface and checks that its function return the
expected values.
Note that this test does not allocate any sdhci structure, it's all done by the
qtest walking graph mechanism

Add pci-bus-spapr node, that produces pci-bus. Move QPCIBusSPAPR struct
declaration in its header (since it will be needed by other drivers)
and introduce a setter method for drivers that do not need to allocate
but have to initialize QPCIBusSPAPR.

Add pseries machine for the ppc64 QEMU binary. This machine contains a
spapr-pci-host-bridge driver, that contains itself a pci-bus-spapr
that produces the pci-bus interface.

The Qgraph framework makes any test using
pci bus run the same function using pci-pci and
pci-spapr bus. However, some tests are not ready to use
the spapr bus, due to a MSI bug. Until it does not get
fixed, this flag allows them to skip the test

Convert tests/e1000e-test in qgraph test node, e1000e-test. This test
consumes an e1000e interface and checks that its function return the
expected values.
Note that this test does not allocate any e1000e structure, it's all done by the
qtest walking graph mechanism

Add QOSGraphObject to QVirtioPCIDevice structure, with a basic
constructor. virtio-pci is not present in qgraph, since it
will be used as starting point by its subclasses (virtio-*-pci)

Add virtio-mmio node in qgraph framework.
virtio-mmio produces virtio-bus, the interface consumed by all virtio-*-device
nodes.
Being a memory-mapped device, it doesn't have to provide a constructor
to qgraph, since it's always "contained" inside some other nodes.

Add arm/virt machine to the graph. This machine contains virtio-mmio, so
its constructor must take care of setting it properly when called.

Add qgraph nodes for virtio-serial-pci and virtio-serial-device.
Both nodes produce virtio-serial, but virtio-serial-pci receives
a pci-bus and uses virtio-pci QOSGraphObject and functions,
while virtio-serial-device receives a virtio-bus and implements
its own functions

Convert tests/virtio-console-test and tests/virtio-serial-test
in qgraph test node. This test consumes a virtio-serial interface
and checks that its function return the expected values.
Note that this test does not allocate any virtio-console or
virtio-serial structure, it's all done by the qtest walking graph mechanism

Add qgraph nodes for virtio-9p-pci and virtio-9p-device.
Both nodes produce virtio-9p, but virtio-9p-pci receives
a pci-bus and overrides virtio-pci QOSGraphObject and its functions,
while virtio-9p-device receives a virtio and implements
its own functions

To: qemu-devel; +Cc: Emanuele Giuseppe Esposito, Laurent Vivier, Thomas Huth
From: Emanuele Giuseppe Esposito <e.emanuelegiuseppe@gmail.com>
Add qgraph nodes for virtio-balloon-pci and virtio-balloon-device.
Both nodes produce virtio-balloon, but virtio-balloon-pci receives
a pci-bus and uses virtio-pci QOSGraphObject and functions,
while virtio-balloon-device receives a virtio and implements
its own functions

Add qgraph nodes for virtio-rng-pci and virtio-rng-device.
Both nodes produce virtio-rng, but virtio-rng-pci receives
a pci-bus and uses virtio-pci QOSGraphObject and functions,
while virtio-rng-device receives a virtio and implements
its own functions

Convert tests/virtio-rng-test in qgraph test node,
virtio-rng-test. This test consumes a virtio-rng interface
and checks that its function return the expected values.
Some functions are implemented only for virtio-rng-pci, so they
don't consume virtio-rng, but virtio-rng-pci
Note that this test does not allocate any virtio-rng structure,
it's all done by the qtest walking graph mechanism

Add qgraph nodes for virtio-blk-pci and virtio-blk-device.
Both nodes produce virtio-blk, but virtio-blk-pci receives
a pci-bus and uses virtio-pci QOSGraphObject and functions,
while virtio-blk-device receives a virtio and implements
its own functions

Convert tests/virtio-blk-test in qgraph test node,
virtio-blk-test. This test consumes a virtio-blk interface
and checks that its function return the expected values.
Some functions are implemented only for virtio-blk-pci, so they
don't consume virtio-blk, but virtio-blk-pci
Note that this test does not allocate any virtio-blk structure,
it's all done by the qtest walking graph mechanism. The allocator
is also provided by qgraph; remove malloc-generic.c and malloc-generic.h
which are not used anymore.

Add qgraph nodes for virtio-net-pci and virtio-net-device.
Both nodes produce virtio-net, but virtio-net-pci receives
a pci-bus and overrides virtio-pci QOSGraphObject and its functions,
while virtio-net-device receives a virtio and implements
its own functions

Convert tests/virtio-net-test in qgraph test node,
virtio-net-test. This test consumes a virtio-net interface
and checks that its function return the expected values.
Some functions are implemented only for virtio-net-pci, so they
don't consume virtio-net, but virtio-net-pci
Note that this test does not allocate any virtio-net structure,
it's all done by the qtest walking graph mechanism

Initialize the additional virtqueues if they are supported.
This is needed to switch vhost-user-test's multiqueue test
to the virtio-net qgraph.

Some tests are using a small amount of RAM for the guest (2 MiB) in order to
save host memory, others are using 512 MiB.
However, pSeries machines only support multiples of 256 MiB. Using 256
MiB of memory does not use more host memory than now, even for the
migration test that starts two guests, and it allows running the test on
pSeries too.
This of course is not optimal, it would be nice to let the qgraph machine object
judge how much memory to provide. This is left for future work, together
with a more generic framework that wraps the QEMU command line.

Convert tests/virtio-net-test in qgraph test node,
virtio-net-test. This test consumes a virtio-net interface
and checks that its function return the expected values.
Note that this test does not allocate any virtio-net structure,
it's all done by the qtest walking graph mechanism. Nevertheless,
vhost-user-test is a bit more complex than the other tests, because
it requires more complicated setup of back-ends and thus almost each
test has a slightly different opts.before function.

Add qgraph nodes for virtio-scsi-pci and virtio-scsi-device.
Both nodes produce virtio-scsi, but virtio-scsi-pci receives
a pci-bus and uses virtio-pci QOSGraphObject and its functions,
while virtio-scsi-device receives a virtio and implements
its own functions

Convert tests/virtio-scsi-test in qgraph test node,
virtio-scsi-test. This test consumes a virtio-scsi interface
and checks that its function return the expected values.
Some functions are implemented only for virtio-scsi-pci, so they
don't consume virtio-scsi, but virtio-scsi-pci
Note that this test does not allocate any virtio-scsi structure,
it's all done by the qtest walking graph mechanism

Convert tests/ipoctal232-test to a driver node; currently it runs
the PCI nop test only, therefore we're not placing it in tests/libqos.
This test creates a tpci200 node that produces an interface ipack
consumed by the ipoctal232 device.

Convert tests/ne2000-test to a driver node; currently it runs
the PCI nop test only, therefore we're not placing it in tests/libqos.
The actual device consumed by the test is ne2k_pci.
