I'm converting from qdev_create()/qdev_init_nofail() to qdev_new()/qdev_realize_and_unref(); recent commit "qdev: New qdev_new(), qdev_realize(), etc." explains why. PCI devices use qdev_create() through pci_create() and pci_create_multifunction(). Provide pci_new(), pci_new_multifunction(), and pci_realize_and_unref() for converting PCI devices. Cc: Michael S.

2020-06-15qdev: Convert uses of qdev_set_parent_bus() with CoccinelleMarkus Armbruster41-87/+43
In addition to the qdev_create() patterns converted so far, we have a qdev_set_parent_bus() pattern. Mostly when we embed a device in a parent device rather than allocating it on the heap. This pattern also puts devices in the dangerous "no QOM parent, but plugged into bus" state I explained in recent commit "qdev: New qdev_new(), qdev_realize(), etc." Apply same solution: convert to qdev_realize().

2020-06-15qdev: New qdev_new(), qdev_realize(), etc.Markus Armbruster2-0/+104
We commonly plug devices into their bus right when we create them, like this: dev = qdev_create(bus, type_name); Note that @dev is a weak reference. The reference from @bus to @dev is the only strong one. We realize at some later time, either with object_property_set_bool(OBJECT(dev), true, "realized", errp); or its convenience wrapper qdev_init_nofail(dev); If @dev still has no QOM parent then, realizing makes the /machine/unattached/ orphanage its QOM parent. Note that the device returned by qdev_create() is plugged into a bus, but doesn't have a QOM parent, yet. Until it acquires one, unrealizing the bus will hang in bus_unparent(): while ((kid = QTAILQ_FIRST(&bus->children)) != NULL) { DeviceState *dev = kid->child; object_unparent(OBJECT(dev)); } object_unparent() does nothing when its argument has no QOM parent, and the loop spins forever. Device state "no QOM parent, but plugged into bus" is dangerous. Paolo suggested to delay plugging into the bus until realize. We need to plug into the parent bus before we call the device's realize method, in case it uses the parent bus. So the dangerous state still exists, but only within realization, where we can manage it safely. This commit creates infrastructure to do this: dev = qdev_new(type_name); ... qdev_realize_and_unref(dev, bus, errp) Note that @dev becomes a strong reference here. qdev_realize_and_unref() drops it. There is also plain qdev_realize(), which doesn't drop it. The remainder of this series will convert all users to this new interface. Cc: Michael S.

2020-06-15sd: Hide the qdev-but-not-quite thing created by sd_init()Markus Armbruster1-11/+27
Commit 260bc9d8aa "hw/sd/sd.c: QOMify" QOMified only the device itself, not its users. It kept sd_init() around for non-QOMified users. More than four years later, three such users remain: omap1 (machines cheetah, sx1, sx1-v1) and omap2 (machines n800, n810) are not QOMified, and pl181 (machines integratorcp, realview-eb, realview-eb-mpcore, realview-pb-a8 realview-pbx-a9, versatileab, versatilepb, vexpress-a15, vexpress-a9) is not QOMified properly. The issue I presently have with this: an "sd-card" device should plug into an "sd-bus" (its DeviceClass member bus_type says so), but sd_init() leaves it unplugged. This is normally a bug (I just fixed some instances), and I'd like to assert proper pluggedness to prevent regressions. However, the qdev-but-not-quite thing returned by sd_init() would fail the assertion. Meh. Make sd_init() hide it from QOM/qdev.

sm501_init() and ati_vga_realize() create an "i2c-ddc" device, but neglect to realize it. Affects machines sam460ex, shix, r2d, and fulong2e. In theory, a device becomes real only on realize. In practice, the transition from unreal to real is a fuzzy one. The work to make a device real can be spread between realize methods (fine), instance_init methods (wrong), and board code wiring up the device (fine as long as it effectively happens on realize). Depending on what exactly is done where, a device can work even when we neglect to realize it. This one appears to work. Nevertheless, it's a clear misuse of the interface. Even when it works today (more or less by chance), it can break tomorrow. Fix by realizing it right away.

2020-06-15arm/aspeed: Rework NIC attachmentCédric Le Goater3-4/+15
The number of MACs supported by an Aspeed SoC is defined by "macs_num" under the SoC model, that is two for the AST2400 and AST2500 and four for the AST2600. The model initializes the maximum number of supported MACs but the number of realized devices is capped by the number of network device back-ends defined on the command line. This can leave unrealized devices hanging around in the QOM composition tree. To get virtual hardware that matches the physical hardware, you have to pass exactly as many -nic options as there are MACs, and some of them must be -nic none: * Machines ast2500-evb, palmetto-bmc, romulus-bmc, sonorapass-bmc, swift-bmc, and witherspoon-bmc: two -nic, and the second one must be -nic none. * Machine ast2600-evb: four -nic, the first one must be -nic none. * Machine tacoma-bmc: four nic, the first two and the last one must be -nic none. Modify the machine initialization to define which MACs are attached to a network device back-end using a bit-field property "macs-mask" and let the SoC realize all network devices. The default setting of "macs-mask" is "use MAC0" only, which works for all our AST2400 and AST2500 machines. The AST2600 machines have different configurations. The AST2600 EVB machine activates MAC1, MAC2 and MAC3 and the Tacoma BMC machine activates MAC2. Incompatible CLI change: -nic options now apply to *active* MACs: MAC1, MAC2, MAC3 for ast2600-evb, MAC2 for tacoma-bmc, and MAC0 for all the others. The machines now always get all MACs as they should.

2020-06-15arm/aspeed: Compute the number of CPUs from the SoC definitionCédric Le Goater3-26/+32
Commit ece09beec457 ("aspeed: introduce a configurable number of CPU per machine") was a convient change during bringup but the Aspeed SoCs have a fixed number of CPUs : one for the AST2400 and AST2500, and two for the AST2600. When the number of CPUs configured with -smp is less than the SoC's fixed number, the "unconfigured" CPUs are left unrealized. This can happen for machines ast2600-evb and tacoma-bmc, where the SoC's fixed number is 2. To get virtual hardware that matches the physical hardware, you have to pass -smp cpus=2 (or its sugared form -smp 2). We normally reject -smp cpus=N when N exceeds the machine's limit. Except we ignore cpus=2 (and only cpus=2) with a warning for machines ast2500-evb, palmetto-bmc, romulus-bmc, sonorapass-bmc, swift-bmc, and witherspoon-bmc. Remove the "num-cpu" property from the SoC state and use the fixed number of CPUs defined in the SoC class instead. Compute the default, min, max number of CPUs of the machine directly from the SoC class definition. Machines ast2600-evb and tacoma-bmc now always get their second CPU as they should.

2020-06-12xen: fix build without pci passthroughAnthony PERARD6-6/+41
Xen PCI passthrough support may not be available and thus the global variable "has_igd_gfx_passthru" might be compiled out. Common code should not access it in that case. Unfortunately, we can't use CONFIG_XEN_PCI_PASSTHROUGH directly in xen-common.c so this patch instead move access to the has_igd_gfx_passthru variable via function and those functions are also implemented as stubs. The stubs will be used when QEMU is built without passthrough support. Now, when one will want to enable igd-passthru via the -machine property, they will get an error message if QEMU is built without passthrough support.

2020-06-12pci: Display PCI IRQ pin in "info pci"Peter Xu1-0/+1
Sometimes it would be good to be able to read the pin number along with the IRQ number allocated. Since we'll dump the IRQ number, no reason to not dump the pin information. For example, the vfio-pci device will overwrite the pin with the hardware pin number. It would be nice to know the pin number of one assigned device from QMP/HMP.

The ‘enable’ parameter to the vhost_migration_log() function is given as an int, but "true"/"false" values are passed in wherever it is invoked. Inside the function itself it is only ever compared with bool values. Therefore the parameter value itself should be changed to bool.
