KVM: Introduce kvm_host_page_size

2010-03-01T15:36:08+00:00

This patch introduces a generic function to find out the
host page size for a given gfn. This function is needed by
the kvm iommu code. This patch also simplifies the x86
host_mapping_level function.

KVM: Lazify fpu activation and deactivation

2010-03-01T15:35:50+00:00

Defer fpu deactivation as much as possible - if the guest fpu is loaded, keep
it loaded until the next heavyweight exit (where we are forced to unload it).
This reduces unnecessary exits.

We also defer fpu activation on clts; while clts signals the intent to use the
fpu, we can't be sure the guest will actually use it.

KVM: x86: switch kvm_set_memory_alias to SRCU update

2010-03-01T15:35:45+00:00

Using a similar two-step procedure as for memslots.

KVM: introduce kvm->srcu and convert kvm_set_memory_region to SRCU update

2010-03-01T15:35:44+00:00

Use two steps for memslot deletion: mark the slot invalid (which stops
instantiation of new shadow pages for that slot, but allows destruction),
then instantiate the new empty slot.

Also simplifies kvm_handle_hva locking.

KVM: use gfn_to_pfn_memslot in kvm_iommu_map_pages

2010-03-01T15:35:44+00:00

So its possible to iommu map a memslot before making it visible to
kvm.
