[Xen-devel] [PATCH v15 0/3] VT-d Device-TLB flush issue

["Jan Beulich" <JBeulich@xxxxxxxx>]

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.
