I think these are the 5 patches that we require from Intel pass-through se= ries, vfio/iommufd: Implement [at|de]tach_hwpt handlers vfio/iommufd: Implement HostIOMMUDeviceClass::realize_late() handler HostIOMMUDevice: Introduce realize_late callback vfio/iommufd: Add properties and handlers to TYPE_HOST_IOMMU_DEVICE_IOMMUFD backends/iommufd: Add helpers for invalidating user-managed HWPT See the commits from here, https://github.com/hisilicon/qemu/commit/bbdc65af38fa5723f1bd9b026e29273090= 1f57b5 [CC Zhenzhong] Hi Zhenzhong, Just wondering what your plans are for the above patches. If it make sense= and you are fine with it, I think it is a good idea one of us can pick up those fro= m that series and sent out separately so that it can get some review and take it forward. Thanks, Shameer =20
