我有一个可能有buggy的硬件和一个可能有buggy的用户空间驱动程序,它依赖于vfio-pci内核驱动程序。我想在不处理硬件的情况下测试驱动程序。我认为理想的解决方案应该是这样的:运行除硬件(应用程序、用户空间驱动程序、VFIO驱动程序)之外的整个堆栈,并拦截VFI
using it to generically enable VFs. This is entirely not the purpose of vfio-pci SR-IOV support. If the goal is only to create VFs with no userspace or VM driver for the PF, then use pci_pf_stub. The pci_pf_stub driver is for SR-IOV PFs that do not require a PF driver other...
The vfio_pci ids= should be a comma separated list of all vendor-id:device-id pairs you want stubbed by the VFIO driver. Remember that you must pass through all PCI devices in the same IOMMU group. In this case here, I’m passthrough through both the audio and video components of the...
I'm testing KVM device(pci) pass-through with new 3.x kernel (RHEL 7.0) It seems new device pass-through framework, VFIO, has been merged since kernel 3.6. Before VFIO (prior pci-stub) we could simply assign each PF or VF to different guest VM freely but with VFIO, kernel ...
