Hi, all
'virsh dump' can not work when host pci device is used by guest. We have
discussed this issue here:

We have determined to introduce a new command dump to dump memory. The core
file's format can be elf.

All backends now use 'get_api_name' to build the name of the routines that are

The old 'get_name' is still available to refer to the name of an event.

Rename msix_supported to msi_supported and control MSI and MSI-X
activation this way. That was likely to original intention for this
flag, but MSI support came after MSI-X.

This introduces the alternative APIC backend which makes use of KVM's
in-kernel device model. External NMI injection via LINT1 is emulated by
checking the current state of the in-kernel APIC, only injecting a NMI
into the VCPU if LINT1 is unmasked and configured to DM_NMI.
MSI is not yet supported
Introduce a memory region type that can reserve I/O space. Such regions
are useful for modeling I/O that is only handled outside of QEMU, i.e.
in the context of an accelerator like KVM.
Any access to such a region from QEMU is a bug, but could theoretically
be triggered by guest code (DMA to reser
Introduce the alternative i8259 backend that exploits KVM in-kernel

Analogously to the APIC, we will reuse some parts of the user space
i8259 model for KVM. Again, we create a PIC backend infrastructure and
provide hooks for init, reset, and vmload/save. This also introduces a
common helper to instantiate a single i8259 chip from the cascade-
creating i8259_init fu

On real hardware, NMI button events are injected via the LINT1 line of
the APICs. E.g. kdump expect this wiring and gets upset if the per-APIC
LINT1 mask is not respected, i.e. if NMIs are injected to VCPUs that
should not receive them. Change the APIC emulation code to reflect this.
Based on qemu
KVM is forced to disable the IRQ0 override when we run with in-kernel
irqchip but without IRQ routing support of the kernel. Set the fwcfg
value correspondingly. This aligns us with qemu-kvm.

Add the basic infrastructure to active in-kernel irqchip support, inject
interrupts into these models, and maintain IRQ routes.
Routing is optional and depends on the host arch supporting
KVM_CAP_IRQ_ROUTING. When it's not available on x86, we looe the HPET as
we can't route GSI0 to IOAPIC pin 2.

All LVTs are masked on reset, so the timer becomes ineffective. Letting
it tick nevertheless is harmless, but will at least create a spurious
trace event.

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.
This patch therefore factors out the gen
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. Introduce an APIC backend concept to encapsulate those
parts that will tell user space and KVM model apart. The backend offers
callback hooks for ini
This introduces the KVM-accelerated IOAPIC backend and extends the IRQ
routing setup by the 0->2 redirection when needed.
The IOAPIC gains a KVM-specific property that allows to define the GSI
base for injecting interrupts into the kernel model. This will allow to
disentangle PIC and IOAPIC pins f
Split up the IOAPIC analogously to APIC and i8259. KVM will share the
device description, reset logic and certain init parts with the user
space model.
