KVM: PPC: Add OSI hypercall interface

2010-05-17T09:17:10+00:00

MOL uses its own hypercall interface to call back into userspace when
the guest wants to do something.

So let's implement that as an exit reason, specify it with a CAP and
only really use it when userspace wants us to.

The only user of it so far is MOL.

KVM: Add support for enabling capabilities per-vcpu

2010-05-17T09:17:09+00:00

Some times we don't want all capabilities to be available to all
our vcpus. One example for that is the OSI interface, implemented
in the next patch.

In order to have a generic mechanism in how to enable capabilities
individually, this patch introduces a new ioctl that can be used
for this purpose. That way features we don't want in all guests or
userspace configurations can just not be enabled and we're good.

KVM: PPC: Allow userspace to unset the IRQ line

2010-05-17T09:16:51+00:00

Userspace can tell us that it wants to trigger an interrupt. But
so far it can't tell us that it wants to stop triggering one.

So let's interpret the parameter to the ioctl that we have anyways
to tell us if we want to raise or lower the interrupt line.

KVM: x86: Add support for saving&restoring debug registers

2010-04-25T09:39:10+00:00

So far user space was not able to save and restore debug registers for
migration or after reset. Plug this hole.

KVM: x86: Save&restore interrupt shadow mask

2010-04-25T09:38:28+00:00

The interrupt shadow created by STI or MOV-SS-like operations is part of
the VCPU state and must be preserved across migration. Transfer it in
the spare padding field of kvm_vcpu_events.interrupt.

As a side effect we now have to make vmx_set_interrupt_shadow robust
against both shadow types being set. Give MOV SS a higher priority and
skip STI in that case to avoid that VMX throws a fault on next entry.

KVM: PPC: Add capability for paired singles

2010-04-25T09:37:47+00:00

We need to tell userspace that we can emulate paired single instructions.
So let's add a capability export.
