Subject: [PATCH 4/8] Staging: hv: vmbus: Do not enable auto eoi
Date: Mon, 15 Aug 2011 15:12:03 -0700 [thread overview]
Message-ID: <1313446327-10650-4-git-send-email-kys@microsoft.com> (raw)
In-Reply-To: <1313446327-10650-1-git-send-email-kys@microsoft.com>
The standard interrupt handling in Linux issues an eoi when the
interrupt handling is done. So, setup the vmbus interrupt without
enabling auto eoi.
