Subject: [PATCH v9 0/3] Check VT-d Device-TLB flush error
Date: Fri, 17 Jun 2016 11:37:22 +0800	[thread overview]
Message-ID: <1466134645-50852-1-git-send-email-quan.xu@intel.com> (raw)

From: Quan Xu <quan.xu@intel.com>

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'.
