2016-07-04xen: fix ram init regressionGerd Hoffmann1-0/+3
Commit "8156d48 pc: allow raising low memory via max-ram-below-4g option" causes a regression on xen, because it uses a different memory split. This patch initializes max-ram-below-4g to zero and leaves the initialization to the memory initialization functions. That way they can pick different default values (max-ram-below-4g is zero still) or use the user supplied value (max-ram-below-4g is non-zero). Also skip the whole ram split calculation on Xen. xen_ram_init() does its own split calculation anyway so it is superfluous, also this way xen_ram_init can actually see whenever max-ram-below-4g is zero or not.

2016-06-29ICH9 LPC: move call of isa_bus_irqs to 'realize' methodEfimov Vasily1-3/+0
The isa_bus_irqs function initializes ISA bus IRQ array pointer with specified value. Previously the ICH9 LPC bridge model did not have its own IRQs but only IRQ pointer cache. And same GSI were used for ISA bus and other sources behind the bridge (PCI, SCI). Hence, the pc_q35_init was only possible place to setup both ISA bus IRQs and the bridge IRQ cache. As a result, the call of isa_bus_irqs was made from pc_q35_init. Now the ICH9 LPC bridge has its own output IRQs which are connected to GSI. The output IRQs are already used to route IRQs from PCI and SCI. The patch makes the ICH9 LPC bridge output IRQs to used for ISA bus too.

For compatibility reasons PC/Q35 will start with legacy CPU hotplug interface by default but with new CPU hotplug AML code since 2.7 machine type. That way legacy firmware that doesn't use QEMU generated ACPI tables will be able to continue using legacy CPU hotplug interface. While new machine type, with firmware supporting QEMU provided ACPI tables, will generate new CPU hotplug AML, which will switch to new CPU hotplug interface when guest OS executes its _INI method on ACPI tables loading.

2016-01-21target-i386: Add support to migrate vcpu's TSC rateHaozhong Zhang1-0/+2
This patch enables migrating vcpu's TSC rate. If KVM on the destination machine supports TSC scaling, guest programs will observe a consistent TSC rate across the migration. If TSC scaling is not supported on the destination machine, the migration will not be aborted and QEMU on the destination will not set vcpu's TSC rate to the migrated value. If vcpu's TSC rate specified by CPU option 'tsc-freq' on the destination machine is inconsistent with the migrated TSC rate, the migration will be aborted. For backwards compatibility, the migration of vcpu's TSC rate is disabled on pc-*-2.5 and older machine types.

2015-11-04pc: Set hw_version on all machine classesEduardo Habkost1-0/+10
In 2012, QEMU had a bug where it exposed QEMU version information to the guest, meaning a QEMU upgrade would expose different hardware to the guest OS even if the same machine-type is being used. The bug was fixed by commit 93bfef4c6e4b23caea9d51e1099d06433d8835a4, on all machines up to pc-1.0. But we kept introducing the same bug on all newer machines since then. That means we are breaking guest ABI every time QEMU was upgraded. Fix this by setting the hw_version on all PC machines, making sure the hardware won't change when upgrading QEMU. Note that QEMU_VERSION was "1.0" in QEMU 1.0, but starting on QEMU 1.1.0, it started following the "x.y.0" pattern. We have to follow it, to make sure we use the right QEMU_VERSION string from each QEMU release. The 2.5 machine classes could have hw_version unset, because the default value for qemu_get_version() is QEMU_VERSION. But I decided to set it explicitly to QEMU_VERSION so we don't forget to update it to "2.5.0" after we release 2.5.0 and create a 2.6 machine class.

2015-10-02cpu/apic: drop icc bus/bridgeChen Fan1-8/+1
After CPU hotplug has been converted to BUS-less hot-plug infrastructure, the only function ICC bus performs is to propagate reset to LAPICs. However LAPIC could be reset by registering its reset handler after all device are initialized. Do so and drop ~30LOC of not needed anymore ICCBus related code.

mapping DIMMs non contiguously allows to workaround virtio bug reported earlier: http://lists.nongnu.org/archive/html/qemu-devel/2015-08/msg00522.html in this case guest kernel doesn't allocate buffers that can cross DIMM boundary keeping each buffer local to a DIMM.
