* uninorth: use qdev gpios for PCI IRQsMark Cave-Ayland2020-10-181-2/+0Star
| | | | | | | | | | | | | | Currently an object link property is used to pass a reference to the OpenPIC into the PCI host bridge so that pci_unin_init_irqs() can connect the PCI IRQs to the PIC itself. This can be simplified by defining the PCI IRQs as qdev gpios and then wiring up the PCI IRQs to the PIC in the New World machine init function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When split irqchip support was introduced, the meaning of kvm_irqchip_in_kernel() changed: now it only means the LAPIC is in kernel.

While at it, remove the "the user asked us" part in kvm_irqchip_is_split() doc comment. That macro has nothing to do with existence of explicit user-provided options.

Instead of being an error (because of a missing value) or a value for an implied key, they now request help, which is a new boolean output of the parser in addition to the QDict. A new parameter 'p_help' is added to keyval_parse() that contains on return whether help was requested. If NULL is passed, requesting help results in an error and all other cases work like before. Turning previous error cases into help is a compatible extension. The behaviour potentially changes for implied keys: They could previously get 'help' as their value, which is now interpreted as requesting help. This is not a problem in practice because 'help' and '?' are not a valid values for the implied key of any option parsed with keyval_parse(): * audiodev: union Audiodev, implied key "driver" is enum AudiodevDriver, "help" and "?" are not among its values * display: union DisplayOptions, implied key "type" is enum DisplayType, "help" and "?" are not among its values * blockdev: union BlockdevOptions, implied key "driver is enum BlockdevDriver, "help" and "?" are not among its values * export: union BlockExport, implied key "type" is enum BlockExportType, "help" and "?" are not among its values * monitor: struct MonitorOptions, implied key "mode" is enum MonitorMode, "help" and "?" are not among its values * nbd-server: struct NbdServerOptions, no implied key.

| | | | | | | | | | | | | | | | | | | | | | Some code might race with placement of new devices on a bus. We currently first place a (unrealized) device on the bus and then realize it. As a workaround, users that scan the child device list, can check the realized property to see if it is safe to access such a device. Use an atomic write here too to aid with this. A separate discussion is what to do with devices that are unrealized: It looks like for this case we only call the hotplug handler's unplug callback and its up to it to unrealize the device. An atomic operation doesn't cause harm for this code path though.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The changes to come to NUMA support are all guest visible. In theory we could just create a new 5_1 class option flag to avoid the changes to cascade to 5.1 and under. The reality is that these changes are only relevant if the machine has more than one NUMA node. There is no need to change guest behavior that has been around for years needlesly. This new helper will be used by the next patches to determine whether we should retain the (soon to be) legacy NUMA behavior in the pSeries machine. The new behavior will only be exposed if: - machine is pseries-5.2 and newer; - more than one NUMA node is declared in NUMA state.

For commands that are not declared safe to run in a coroutine, the dispatcher drops out of coroutine context by calling the QMP command handler from a bottom half.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This way, a monitor command handler will still be able to access the current monitor, but when it yields, all other code code will correctly get NULL from monitor_cur(). This uses a hash table to map the coroutine pointer to the current monitor of that coroutine. Outside of coroutine context, we associate the current monitor with the leader coroutine of the current thread. Approaches to implement some form of coroutine local storage directly in the coroutine core code have been considered and discarded because they didn't end up being much more generic than the hash table and their performance impact on coroutines not using coroutine local storage was unclear. As the block layer uses a coroutine per I/O request, this is a fast path and we have to be careful. It's safest to just stay out of this path with code only used by the monitor.
