2020-06-15sysbus: New sysbus_realize(), sysbus_realize_and_unref()Markus Armbruster
Sysbus devices almost always plug into the main system bus. qdev_create() even has a convenience feature to make that easy: a null bus argument gets replaced by the main system bus. qdev_realize() and qdev_realize_and_unref() do the same. We can do better. Provide convenience wrappers around qdev_realize() and qdev_realize_and_unref() that don't take a @bus argument. They always pass the main system bus.

2020-06-15qom: Less verbose object_initialize_child()Markus Armbruster
All users of object_initialize_child() pass the obvious child size argument. Almost all pass &error_abort and no properties. Tiresome. Rename object_initialize_child() to object_initialize_child_with_props() to free the name.

2020-06-15ssi: ssi_auto_connect_slaves() never does anything, dropMarkus Armbruster
ssi_auto_connect_slaves(parent, cs_line, bus) iterates over @parent's QOM children @dev of type TYPE_SSI_SLAVE. It puts these on @bus, and sets cs_line[] to qdev_get_gpio_in_named(dev, SSI_GPIO_CS, 0). Suspicious: there is no protection against overrunning cs_line[]. Turns out it's safe because ssi_auto_connect_slaves() never finds any such children. Its called by realize methods of some (but not all) devices providing an SSI bus, and gets passed the device. SSI slave devices are always created with ssi_create_slave_no_init(), optionally via ssi_create_slave(). This adds them to their SSI bus. It doesn't set their QOM parent. ssi_create_slave_no_init() is always immediately followed by qdev_init_nofail(), with no QOM parent assigned, so device_set_realized() puts the device into the /machine/unattached/ orphanage. None become QOM children of a device providing an SSI bus. ssi_auto_connect_slaves() was added in commit b4ae3cfa57 "ssi: Add slave autoconnect helper". I can't see which slaves it was supposed to connect back then.

2020-06-15qdev: New qdev_new(), qdev_realize(), etc.Markus Armbruster
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.

2020-06-15arm/aspeed: Rework NIC attachmentCédric Le Goater
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.

2020-06-15arm/aspeed: Compute the number of CPUs from the SoC definitionCédric Le Goater
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. Visible in "info qom-tree"; here's the change for ast2600-evb: /machine (ast2600-evb-machine) /peripheral (container) /peripheral-anon (container) /soc (ast2600-a1) /a7mpcore (a15mpcore_priv) /a15mp-priv-container[0] (qemu:memory-region) /gic (arm_gic) /gic_cpu[0] (qemu:memory-region) /gic_cpu[1] (qemu:memory-region) + /gic_cpu[2] (qemu:memory-region) /gic_dist[0] (qemu:memory-region) /gic_vcpu[0] (qemu:memory-region) /gic_viface[0] (qemu:memory-region) /gic_viface[1] (qemu:memory-region) + /gic_viface[2] (qemu:memory-region) /unnamed-gpio-in[0] (irq) [...] + /unnamed-gpio-in[160] (irq) [same for 161 to 190...] + /unnamed-gpio-in[191] (irq) Also visible in "info qtree"; here's the change for ast2600-evb: bus: main-system-bus type System dev: a15mpcore_priv, id "" gpio-in "" 128 - gpio-out "sysbus-irq" 5 - num-cpu = 1 (0x1) + gpio-out "sysbus-irq" 10 + num-cpu = 2 (0x2) num-irq = 160 (0xa0) mmio 0000000040460000/0000000000008000 dev: arm_gic, id "" - gpio-in "" 160 - num-cpu = 1 (0x1) + gpio-in "" 192 + num-cpu = 2 (0x2) num-irq = 160 (0xa0) revision = 2 (0x2) has-security-extensions = true has-virtualization-extensions = true num-priority-bits = 8 (0x8) mmio ffffffffffffffff/0000000000001000 mmio ffffffffffffffff/0000000000002000 mmio ffffffffffffffff/0000000000001000 mmio ffffffffffffffff/0000000000002000 mmio ffffffffffffffff/0000000000000100 + mmio ffffffffffffffff/0000000000000100 + mmio ffffffffffffffff/0000000000000200 mmio ffffffffffffffff/0000000000000200 The other machines now reject -smp cpus=2 just like -smp cpus=3 and up.

At this point, the value returned by the backend will be capped at the maximum number of ram slots which can be supported by vhost-user, which is currently set to 8 because of underlying protocol limitations.

2020-06-10KVM: Kick resamplefd for split kernel irqchipPeter Xu
This is majorly only for X86 because that's the only one that supports split irqchip for now. When the irqchip is split, we face a dilemma that KVM irqfd will be enabled, however the slow irqchip is still running in the userspace. It means that the resamplefd in the kernel irqfds won't take any effect and it will miss to ack INTx interrupts on EOIs. One example is split irqchip with VFIO INTx, which will break if we use the VFIO INTx fast path. This patch can potentially supports the VFIO fast path again for INTx, that the IRQ delivery will still use the fast path, while we don't need to trap MMIOs in QEMU for the device to emulate the EIOs (see the callers of vfio_eoi() hook). However the EOI of the INTx will still need to be done from the userspace by caching all the resamplefds in QEMU and kick properly for IOAPIC EOI broadcast. This is tricky because in this case the userspace ioapic irr & remote-irr will be bypassed. However such a change will greatly boost performance for assigned devices using INTx irqs (TCP_RR boosts 46% after this patch applied). When the userspace is responsible for the resamplefd kickup, don't register it on the kvm_irqfd anymore, because on newer kernels (after commit 654f1f13ea56, 5.2+) the KVM_IRQFD will fail if with both split irqchip and resamplefd. This will make sure that the fast path will work for all supported kernels. https://patchwork.kernel.org/patch/10738541/#22609933 Suggested-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Peter Xu <peterx@redhat.com> Message-Id: <20200318145204.74483-5-peterx@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
