kvm: i386: Add classic PCI device assignment

This adds PCI device assignment for i386 targets using the classic KVM
interfaces. This version is 100% identical to what is being maintained
in qemu-kvm for several years and is supported by libvirt as well. It is...

kvm: i8254: Cache kernel clock offset in KVMPITState

To prepare the final fix for clock calibration issues with the in-kernel
PIT, we want to cache the offset between vmclock and the clock used by
the in-kernel PIT. So far, we only need to update it when the VM state...

kvm: i8254: Finish time conversion fix

0cdd3d1444 fixed reading back the counter load time from the kernel
while assuming the kernel would always update its load time on writing
the state. That is only true for channel 1, and so pit_get_channel_info
returned wrong output pin states for high counter values....

kvm: Rename kvm_irqchip_set_irq() to kvm_set_irq()

Rename the function kvm_irqchip_set_irq() to kvm_set_irq(),
since it can be used for sending (asynchronous) interrupts whether
there is a full irqchip model in the kernel or not. (We don't
include 'async' in the function name since asynchronous is the...

make: automatically include dependencies in recursive subdir rules (v2)

I think I understand enough of what's going on in these rules to ensure this is
right. But I could certainly use a second or third opinion...

kvm: i8254: Fix conversion of in-kernel to userspace state

Due to a offset between the clock used to generate the in-kernel
count_load_time (CLOCK_MONOTONIC) and the clock used for processing this
in userspace (vm_clock), reading back the output of PIT channel 2 via...

kvm/apic: correct short memset

kvm_put_apic_state's attempt to clear kapic before setting its
bits cleared sizeof(void) bytes (no more than 8) rather than the
intended 1024 (KVM_APIC_REG_SIZE) bytes. Spotted by coverity.

kvm: x86: Wire up MSI support for in-kernel irqchip

Catch writes to the MSI MMIO region in the KVM APIC and forward them to
the kernel. Provide the kernel support GSI routing, this allows to
enable MSI support also for in-kernel irqchip mode.

kvmclock: guest stop notification

Often when a guest is stopped from the qemu console, it will report spurious
soft lockup warnings on resume. There are kernel patches being discussed that
will give the host the ability to tell the guest that it is being stopped and...
