Joerg Roedel	128ca093cc	kvm: iommu: Add cond_resched to legacy device assignment code ... When assigning devices to large memory guests (>=128GB guest memory in the failure case) the functions to create the IOMMU page-tables for the whole guest might run for a very long time. On non-preemptible kernels this might cause Soft-Lockup warnings. Fix these by adding a cond_resched() to the mapping and unmapping loops.

Paolo Bonzini	c9eab58f64	KVM: x86: move device assignment out of kvm_host.h ... Create a new header, and hide the device assignment functions there. Move struct kvm_assigned_dev_kernel to assigned-dev.c by modifying arch/x86/kvm/iommu.c to take a PCI device struct. Based on a patch by Radim Krcmar <rkrcmark@redhat.com>.

Radim Krčmář	c274e03af7	kvm: x86: move assigned-dev.c and iommu.c to arch/x86/ ... Now that ia64 is gone, we can hide deprecated device assignment in x86. Notable changes: - kvm_vm_ioctl_assigned_device() was moved to x86/kvm_arch_vm_ioctl() The easy parts were removed from generic kvm code, remaining - kvm_iommu_(un)map_pages() would require new code to be moved - struct kvm_assigned_dev_kernel depends on struct kvm_irq_ack_notifier Signed-off-by: Radim Krčmář <rkrcmar@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>	2014-11-23 18:33:36 +01:00
