[Xen-devel] [PATCH] arm/acpi: hide watchdog timer in GTDT table for dom0

2016-11-28 Thread Shanker Donthineni
Either we have to hide the watchdog timer section in GTDT or emulate watchdog timer block for dom0. Otherwise, system gets panic when dom0 accesses its MMIO registers. The current XEN doesn't support virtualization of watchdog timer, so hide the watchdog timer section for dom0. Signed-off-by: Shan

Hi Julien, We are using Fu's [v5] patch series https://patchwork.codeaurora.org/patch/20325/ in our testing. We thought system crash in xen was related to watchdog timer driver, so removed the watchdog timer sections including GT blocks in GTDT to fix the crash. Let me root cause the issue a
