Subject: [PATCH v13 0/3] VT-d Device-TLB flush issue
Date: Wed, 29 Jun 2016 13:59:31 +0800 [thread overview]
Message-ID: <1467179974-57317-1-git-send-email-quan.xu@intel.com> (raw)
From: Quan Xu <quan.xu@intel.com>
This 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).
---
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.
