*	KVM: enable PCI multiple-segments for pass-through device	Zhai, Edwin	2010-03-01	1	-3/+6
\| \| \| \| \| \| \| \| \|	Enable optional parameter (default 0) - PCI segment (or domain) besides BDF, when assigning PCI device to guest. Signed-off-by: Zhai Edwin <edwin.zhai@intel.com> Acked-by: Chris Wright <chrisw@sous-sol.org> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
*	KVM: introduce kvm->srcu and convert kvm_set_memory_region to SRCU update	Marcelo Tosatti	2010-03-01	1	-2/+2
\| \| \| \| \| \| \| \| \| \|	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. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
*	KVM: use gfn_to_pfn_memslot in kvm_iommu_map_pages	Marcelo Tosatti	2010-03-01	1	-7/+6
\| \| \| \| \| \| \|	So its possible to iommu map a memslot before making it visible to kvm. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
*	KVM: modify memslots layout in struct kvm	Marcelo Tosatti	2010-03-01	1	-6/+12
\| \| \| \| \| \| \| \| \|	Have a pointer to an allocated region inside struct kvm. [alex: fix ppc book 3s] Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
*	KVM: Enable snooping control for supported hardware	Sheng Yang	2009-06-10	1	-3/+24
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Memory aliases with different memory type is a problem for guest. For the guest without assigned device, the memory type of guest memory would always been the same as host(WB); but for the assigned device, some part of memory may be used as DMA and then set to uncacheable memory type(UC/WC), which would be a conflict of host memory type then be a potential issue. Snooping control can guarantee the cache correctness of memory go through the DMA engine of VT-d.

*	KVM: Fix assigned devices circular locking dependency	Mark McLoughlin	2009-02-15	1	-4/+2
\| \| \| \| \| \| \| \| \| \| \|	kvm->slots_lock is outer to kvm->lock, so take slots_lock in kvm_vm_ioctl_assign_device() before taking kvm->lock, rather than taking it in kvm_iommu_map_memslots().

*	kvm/iommu: fix compile warning	Joerg Roedel	2009-01-03	1	-1/+1
\| \| \| \| \| \| \|	This fixes a compile warning about a variable thats maybe used uninitialized in the function. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
*	KVM: change KVM to use IOMMU API	Joerg Roedel	2009-01-03	1	-24/+21

*	KVM: rename vtd.c to iommu.c	Joerg Roedel	2009-01-03	1	-0/+217
	Impact: file renamed The code in the vtd.c file can be reused for other IOMMUs as well. So rename it to make it clear that it handle more than VT-d. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
