From cfe0ffd0272f1a6d34d27ac1a7072d1c42d33ad3 Mon Sep 17 00:00:00 2001 From: Hu Tao Date: Mon, 4 Aug 2014 16:16:08 +0800 Subject: pc-dimm: validate node property If user specifies a node number that exceeds the available numa nodes in emulated system for pc-dimm device, the device will report an invalid _PXM to OSPM. Fix this by checking the node property value. Cc: qemu-stable@nongnu.org Signed-off-by: Hu Tao Reviewed-by: Michael S. Tsirkin Signed-off-by: Michael S.
