Subject: [PATCH v7 5/7] KVM : Force vmexit with virtual interrupt delivery
Date: Mon, 1 Apr 2013 08:40:14 +0800 [thread overview]
Message-ID: <1364776816-30772-6-git-send-email-yang.z.zhang@intel.com> (raw)
In-Reply-To: <1364776816-30772-1-git-send-email-yang.z.zhang@intel.com>
From: Yang Zhang <yang.z.zhang@Intel.com>
Need the EOI to track interrupt deliver status, so force vmexit
on EOI for rtc interrupt when enabling virtual interrupt delivery.
