Split piix4_device_hotplug() into hotplug/unplug callbacks and register them as "hotplug-handler" interface implementation of PIIX4_PM device.

2014-02-05pcihp: make pci_read() mmio calback compatible with legacy ACPI hotplugIgor Mammedov1-1/+2
due to recent change introduced by: "pcihp: reduce number of device check events" 'up' field is cleared right after it's read. This is incompatible with legacy BIOS ACPI code where PCNF ACPI method reads this field 32 times. To make pci_read mmio callback compatible with legacy 'up' behavior, pcihp code will need to know in which mode it runs add 'legacy_piix' field to AcpiPciHpState structure and alter register behavior accordingly.

2013-12-23acpi: piix4: remove not needed GPE0 maskIgor Mammedov1-2/+1
Hardcoded GPE0 mask isn't really needed. Since GPE0_STS initialized with all bits cleared and only QEMU itself can set bits there (i.e. guest can only clear bits in it). So guest can't triger SCI by setting _STS & _EN bits and there is not reason to mask out not supported _STS bits since they shouldn't be set by QEMU in the first place.

2013-12-23piix3 piix4: Clean up use of cannot_instantiate_with_device_add_yetMarkus Armbruster1-1/+5
A PIIX3/PIIX4 southbridge has multiple functions. We model each function as a separate qdev. Two of them need some special wiring set up in pc_init1() or mips_malta_init() to work: the ISA bridge at 01.0, and the SMBus controller at 01.3. The IDE controller at 01.1 (piix3-ide, piix3-ide-xen, piix4-ide) has always had cannot_instantiate_with_device_add_yet set, but there is no obvious reason why device_add could not work for them. Drop it. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Marcel Apfelbaum <marcel.a@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-12-23qdev: Replace no_user by cannot_instantiate_with_device_add_yetMarkus Armbruster1-1/+1
In an ideal world, machines can be built by wiring devices together with configuration, not code. Unfortunately, that's not the world we live in right now. We still have quite a few devices that need to be wired up by code. If you try to device_add such a device, it'll fail in sometimes mysterious ways. If you're lucky, you get an unmysterious immediate crash. To protect users from such badness, DeviceClass member no_user used to make device models unavailable with -device / device_add, but that regressed in commit 18b6dad. The device model is still omitted from help, but is available anyway. Attempts to fix the regression have been rejected with the argument that the purpose of no_user isn't clear, and it's prone to misuse. This commit clarifies no_user's purpose. Anthony suggested to rename it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which I shorten somewhat to keep checkpatch happy. While there, make it bool. Every use of cannot_instantiate_with_device_add_yet gets a FIXME comment asking for rationale. The next few commits will clean them all up, either by providing a rationale, or by getting rid of the use. With that done, the regression fix is hopefully acceptable.

2013-11-05qdev: Drop misleading qdev_free() functionStefan Hajnoczi1-1/+1
The qdev_free() function name is misleading since all the function does is unlink the device from its parent. The device is not necessarily freed. The device will be freed when its QObject refcount reaches zero. It is usual for the parent (bus) to hold the final reference but there are cases where something else holds a reference so "free" is a misleading name. Call object_unparent(obj) directly instead of having a qdev wrapper function.

2013-09-03cpu: Replace qemu_for_each_cpu()Andreas Färber1-11/+9
It was introduced to loop over CPUs from target-independent code, but since commit 182735efaf956ccab50b6d74a4fed163e0f35660 target-independent CPUState is used. A loop can be considered more efficient than function calls in a loop, and CPU_FOREACH() hides implementation details just as well, so use that instead.
