From: Quan Xu <quan.xu@xxxxxxxxx> these patches fix current timeout concern and also allow limited ATS support. these patches are the rest ones: 1. move the domain crash logic up to the generic IOMMU layer 2. If Device-TLB flush timed out, we hide the target ATS device immediately. By hiding the device, we make sure it can't be assigned to any domain any longer (see device_assigned). Quan Xu (3): IOMMU/ATS: use a struct pci_dev * instead of SBDF IOMMU: add domain crash logic VT-d: fix Device-TLB flush timeout issue --- v15: Carried out my own review comments now that Quan left Intel. --- Not covered in this series: a) Eliminate the panic() in IOMMU_WAIT_OP, used only in VT-d register read/write. Further discussion is required on whether and how to improve it. b) Handle IOTLB/Context/IEC flush timeout. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx https://lists.xen.org/xen-devel
