kvmvapic: Introduce TPR access optimization for Windows guests

This enables acceleration for MMIO-based TPR registers accesses of
32-bit Windows guest systems. It is mostly useful with KVM enabled,
either on older Intel CPUs (without flexpriority feature, can also be...

target-i386: Add infrastructure for reporting TPR MMIO accesses

This will allow the APIC core to file a TPR access report. Depending on
the accelerator and kernel irqchip mode, it will either be delivered
right away or queued for later reporting.

In TCG mode, we can restart the triggering instruction and can therefore...

Merge remote-tracking branch 'qemu-kvm/uq/master' into staging

  • qemu-kvm/uq/master:
    apic: Fix legacy vmstate loading for KVM
    kvm: Implement kvm_irqchip_in_kernel like kvm_enabled
    kvm: Allow to set shadow MMU size

qom: Unify type registration

Replace device_init() with generalized type_init().

While at it, unify naming convention: type_init([$prefix_]register_types)
Also, type_init() is a function, so add preceding blank line where
necessary and don't put a semicolon after the closing brace....

apic: Fix legacy vmstate loading for KVM

Also in case of loading pre-vmstate machines, we also need to open-code
the reading of the timer expires value and instead call the post_load
callback to apply it (or not). This fixes loading of legacy states into...

qdev: register all types natively through QEMU Object Model

This was done in a mostly automated fashion. I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.

The first step was a sed-based addition of the parent type to the subclass...

sysbus: apic: ioapic: convert to QEMU Object Model

This converts three devices because apic and ioapic are subclasses of sysbus.
Converting subclasses independently of their base class is prohibitively hard.

qdev: move qdev->info to class

Right now, DeviceInfo acts as the class for qdev. In order to switch to a
proper ObjectClass derivative, we need to ween all of the callers off of
interacting directly with the info pointer.

apic: Factor out base class for KVM reuse

The KVM in-kernel APIC model will reuse parts of the user space model
while providing the same frontend view to guest and most management
interfaces.

Factor out an APIC base class to encapsulate those parts that will be...

apic: Open-code timer save/restore

To enable migration between accelerated and non-accelerated APIC models,
we will need to handle the timer saving and restoring specially and can
no longer rely on the automatics of VMSTATE_TIMER. Specifically,
accelerated model will not start any QEMUTimer....
