CONFIG_KVM_DEVICE_ASSIGNMENT: KVM legacy PCI device assignment support (DEPRECATED)

General informations

The Linux kernel configuration item CONFIG_KVM_DEVICE_ASSIGNMENT has multiple definitions:

KVM legacy PCI device assignment support (DEPRECATED) found in arch/x86/kvm/Kconfig

The configuration item CONFIG_KVM_DEVICE_ASSIGNMENT:

• prompt: KVM legacy PCI device assignment support (DEPRECATED)
• type: bool
• depends on: CONFIG_KVM && CONFIG_PCI && CONFIG_IOMMU_API
• defined in arch/x86/kvm/Kconfig
• found in Linux kernels: 4.2–4.11

Help text

Provide support for legacy PCI device assignment through KVM. The kernel now also supports a full featured userspace device driver framework through VFIO, which supersedes this support and provides better security.

If unsure, say N.
