Subject: [PATCH 03/16] x86/xen/MSI: Use MSI controller framework to configure MSI/MSI-X irq
Date: Mon, 27 Oct 2014 21:22:09 +0800 [thread overview]
Message-ID: <1414416142-31239-4-git-send-email-wangyijing@huawei.com> (raw)
In-Reply-To: <1414416142-31239-1-git-send-email-wangyijing@huawei.com>
Use MSI controller framework instead of arch MSI functions to configure
MSI/MSI-X irq. So we can manage MSI/MSI-X irq in a unified framework.
