Subject: [v5 3/9] iommu, x86: Abstract modify_irte() to accept two format of irte
Date: Wed, 20 May 2015 13:15:31 +0800 [thread overview]
Message-ID: <1432098937-19527-4-git-send-email-feng.wu@intel.com> (raw)
In-Reply-To: <1432098937-19527-1-git-send-email-feng.wu-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>
After introducing VT-d posted-interrupts, we have two format
of IRTE: remapped and posted. This patch make modify_irte()
suitable for both of them.
