We plan to make use of the First-Level Translation Support (FLTS) feature that Intel mentions in the VT-d specification [1]. However, it is unclear which CPU generations precisely support that functionality. We have tested with Cascade Lake and Ice Lake-SP processors, however, neither ex...
Embodiments also provide device-independent structures and methods of implementation, allowing greater generality of software (fewer specific software versions, in turn reducing development costs).The designation of the inventor has not yet been filed...

IOMMU(Input/Output Memory Management Unit)是一种硬件设备,用于在CPU和I/O设备之间提供内存管理功能。它可以在虚拟化环境中防止I/O设备直接访问宿主机的物理内存,从而提高安全性、可靠性和性能。 将IOMMU设置为non-strict模式通常是为了提高性能。在strict模式下,IOMMU会严格限制设备只能访问为其分配的内存区域。这...
