Subject: [PATCH v4 22/27] xen/arm: exynos5: Blacklist MCT device
Date: Fri, 13 Sep 2013 13:49:29 +0100 [thread overview]
Message-ID: <1379076574-28316-23-git-send-email-julien.grall@linaro.org> (raw)
In-Reply-To: <1379076574-28316-1-git-send-email-julien.grall@linaro.org>
The Multi Core Timer (MCT) is a Samsung specific device.
This device tries to route IRQ in non-boot CPU which is not yet handled by Xen.
The user will see randomly dom0 hang, but I'm not sure that is the real reason.
