[Xen-devel] [PATCH v9 0/3] Check VT-d Device-TLB flush error

["Xu, Quan" <quan.xu@xxxxxxxxx>]

From: Quan Xu <quan.xu@xxxxxxxxx>

This patch set is a prereq patch set for Patch:'VT-d Device-TLB flush issue'.

While IOMMU Device-TLB flush timed out, xen calls panic() at present. However 
the existing panic()
is going to be eliminated, so we must propagate the IOMMU Device-TLB flush 
error up to the call trees.

This patch set is also based on the discussion of 'abstract model of IOMMU 
unmaping/mapping failures'.

Quan Xu (3):
  vt-d: fix the IOMMU flush issue
  vt-d: propagate the IOMMU Device-TLB flush error up to ME phantom
    functions
  vt-d: add __must_check annotation to IOMMU flush pointers and handlers
