reset to the device by flapping device's link\nthrough setting the slot's link control register, as pciehp_ist() DLLSC\ninterrupt sequence response, pciehp will unload the device driver and\nthen power it off. thus cause an IOMMU device-TLB invalidation (Intel\nVT-d spec, or ATS Invalidation in PCIe spec r6.1) request for non-existence\ntarget device to be sent and deadly loop to retry that
