KVM: introduce kvm_vcpu_on_spin

2009-12-03T07:32:17+00:00

Introduce kvm_vcpu_on_spin, to be used by VMX/SVM to yield processing
once the cpu detects pause-based looping.

KVM: Activate Virtualization On Demand

2009-12-03T07:32:10+00:00

X86 CPUs need to have some magic happening to enable the virtualization
extensions on them. This magic can result in unpleasant results for
users, like blocking other VMMs from working (vmx) or using invalid TLB
entries (svm).

Currently KVM activates virtualization when the respective kernel module
is loaded. This blocks us from autoloading KVM modules without breaking
other VMMs.

To circumvent this problem at least a bit, this patch introduces on
demand activation of virtualization. This means, that instead
virtualization is enabled on creation of the first virtual machine
and disabled on destruction of the last one.

So using this, KVM can be easily autoloaded, while keeping other
hypervisors usable.

Maintain back mapping from irqchip/pin to gsi to speedup
interrupt acknowledgment notifications.

KVM: Change irq routing table to use gsi indexed array

2009-12-03T07:32:07+00:00

Use gsi indexed array instead of scanning all entries on each interrupt
injection.

KVM: Move irq sharing information to irqchip level

2009-12-03T07:32:06+00:00

This removes assumptions that max GSIs is smaller than number of pins.
Sharing is tracked on pin level not GSI level.

tracing: Remove markers

2009-09-18T19:22:08+00:00

Now that the last users of markers have migrated to the event
tracer we can kill off the (now orphan) support code.

KVM: Reduce runnability interface with arch support code

2009-09-10T05:33:13+00:00

Remove kvm_cpu_has_interrupt() and kvm_arch_interrupt_allowed() from
interface between general code and arch code. kvm_arch_vcpu_runnable()
checks for interrupts instead.
