* sysemu: Split sysemu/runstate.h off sysemu/sysemu.hMarkus Armbruster2019-08-163-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | sysemu/sysemu.h is a rather unfocused dumping ground for stuff related to the system-emulator. Evidence: * It's included widely: in my "build everything" tree, changing sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h, down from 5400 due to the previous two commits). * It pulls in more than a dozen additional headers. Split stuff related to run state management into its own header sysemu/runstate.h. Touching sysemu/sysemu.h now recompiles some 850 objects. qemu/uuid.h also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400 to 4200. Touching new sysemu/runstate.h recompiles some 500 objects. Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also add qemu/main-loop.h.

* Clean up inclusion of sysemu/sysemu.hMarkus Armbruster2019-08-162-2/+0Star
| | | | | | | | | | | | | | | | | | | | | | In my "build everything" tree, changing sysemu/sysemu.h triggers a recompile of some 5400 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Almost a third of its inclusions are actually superfluous. Delete them. Downgrade two more to qapi/qapi-types-run-state.h, and move one from char/serial.h to char/serial.c. hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and stubs/semihost.c define variables declared in sysemu/sysemu.h without including it. The compiler is cool with that, but include it anyway. This doesn't reduce actual use much, as it's still included into widely included headers. The next commit will tackle that.

| | | | | | | | | | | | | | | | | | | | | | | | | In my "build everything" tree, changing hw/qdev-properties.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Many places including hw/qdev-properties.h (directly or via hw/qdev.h) actually need only hw/qdev-core.h. Include hw/qdev-core.h there instead. hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h and hw/qdev-properties.h, which in turn includes hw/qdev-core.h. Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h. While there, delete a few superfluous inclusions of hw/qdev-core.h. Touching hw/qdev-properties.h now recompiles some 1200 objects.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we do device realization like below: hotplug_handler_pre_plug() dc->realize() hotplug_handler_plug() Before we do device realization and plug, we should allocate necessary resources and check if memory-hotplug-support property is enabled. At the piix4 and ich9, the memory-hotplug-support property is checked at plug stage. This means that device has been realized and mapped into guest address space 'pc_dimm_plug()' by the time acpi plug handler is called, where it might fail and crash QEMU due to reaching g_assert_not_reached() (piix4) or error_abort (ich9). Fix it by checking if memory hotplug is enabled at pre_plug stage where we can gracefully abort hotplug request.

* qdev: Let the hotplug_handler_unplug() caller delete the deviceDavid Hildenbrand2019-03-063-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When unplugging a device, at one point the device will be destroyed via object_unparent(). This will, one the one hand, unrealize the removed device hierarchy, and on the other hand, destroy/free the device hierarchy. When chaining hotplug handlers, we want to overwrite a bus hotplug handler by the machine hotplug handler, to be able to perform some part of the plug/unplug and to forward the calls to the bus hotplug handler. For now, the bus hotplug handler would trigger an object_unparent(), not allowing us to perform some unplug action on a device after we forwarded the call to the bus hotplug handler. The device would be gone at that point. machine_unplug_handler(dev) /* eventually do unplug stuff */ bus_unplug_handler(dev) /* dev is gone, we can't do more unplug stuff */ So move the object_unparent() to the original caller of the unplug. For now, keep the unrealize() at the original places of the object_unparent(). For implicitly chained hotplug handlers (e.g. pc code calling acpi hotplug handlers), the object_unparent() has to be done by the outermost caller. So when calling hotplug_handler_unplug() from inside an unplug handler, nothing is to be done. hotplug_handler_unplug(dev) -> calls machine_unplug_handler() machine_unplug_handler(dev) { /* eventually do unplug stuff */ bus_unplug_handler(dev) -> calls unrealize(dev) /* we can do more unplug stuff but device already unrealized */ } object_unparent(dev) In the long run, every unplug action should be factored out of the unrealize() function into the unplug handler (especially for PCI). Then we can get rid of the additonal unrealize() calls and object_unparent() will properly unrealize the device hierarchy after the device has been unplugged. hotplug_handler_unplug(dev) -> calls machine_unplug_handler() machine_unplug_handler(dev) { /* eventually do unplug stuff */ bus_unplug_handler(dev) -> only unplugs, does not unrealize /* we can do more unplug stuff */ } object_unparent(dev) -> will unrealize The original approach was suggested by Igor Mammedov for the PCI part, but I extended it to all hotplug handlers. I consider this one step into the right direction. To summarize: - object_unparent() on synchronous unplugs is done by common code -- "Caller of hotplug_handler_unplug" - object_unparent() on asynchronous unplugs ("unplug requests") has to be done manually -- "Caller of hotplug_handler_unplug" Reviewed-by: Igor Mammedov <imammedo@redhat.com> Acked-by: Cornelia Huck <cohuck@redhat.com> Signed-off-by: David Hildenbrand <david@redhat.com> Message-Id: <20190228122849.4296-2-david@redhat.com> Reviewed-by: Greg Kurz <groug@kaod.org> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>

* qdev: pass an Object * to qbus_set_hotplug_handler()Michael Roth2019-02-172-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Certain devices types, like memory/CPU, are now being handled using a hotplug interface provided by a top-level MachineClass. Hotpluggable host bridges are another such device where it makes sense to use a machine-level hotplug handler. However, unlike those devices, host-bridges have a parent bus (the main system bus), and devices with a parent bus use a different mechanism for registering their hotplug handlers: qbus_set_hotplug_handler(). This interface currently expects a handler to be a subclass of DeviceClass, but this is not the case for MachineClass, which derives directly from ObjectClass. Internally, the interface only requires an ObjectClass, so expose that in qbus_set_hotplug_handler(). Cc: Michael S.

* uuid: Make qemu_uuid_bswap() take and return a QemuUUIDPeter Maydell2019-02-011-4/+2Star
| | | | | | | | | | | | | | | | | | Currently qemu_uuid_bswap() takes a pointer to the QemuUUID to be byte-swapped. This means it can't be used when the UUID to be swapped is in a packed member of a struct. It's also out of line with the general bswap*() functions we provide in bswap.h, which take the value to be swapped and return it. Make qemu_uuid_bswap() take a QemuUUID and return the swapped version. This fixes some clang warnings about taking the address of a packed struct member in block/vdi.c.

* acpi: build TPM Physical Presence interfaceStefan Berger2019-01-182-0/+405
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The TPM Physical Presence interface consists of an ACPI part, a shared memory part, and code in the firmware. Users can send messages to the firmware by writing a code into the shared memory through invoking the ACPI code. When a reboot happens, the firmware looks for the code and acts on it by sending sequences of commands to the TPM. This patch adds the ACPI code. It is similar to the one in EDK2 but doesn't assume that SMIs are necessary to use. It uses a similar datastructure for the shared memory as EDK2 does so that EDK2 and SeaBIOS could both make use of it. I extended the shared memory data structure with an array of 256 bytes, one for each code that could be implemented. The array contains flags describing the individual codes. This decouples the ACPI implementation from the firmware implementation. The underlying TCG specification is accessible from the following page. https://trustedcomputinggroup.org/tcg-physical-presence-interface-specification/ This patch implements version 1.30.
