Subject: [PATCH] IntelSiliconPkg/VTdDxe: return unsupported for exceptionlist
Date: Thu, 26 Oct 2017 10:14:18 +0800	[thread overview]
Message-ID: <1508984058-9452-1-git-send-email-jiewen.yao@intel.com> (raw)

Since the exception list is not a recommended way, we returns
EFI_UNSUPPORTED in the sample code.
