From 8df81d329d167b8c7736789979c69e5fc54f6953 Mon Sep 17 00:00:00 2001 From: Julien Grall Date: Fri, 6 Jun 2014 01:51:15 +0100 Subject: [PATCH 26/48] xen/xenpv: Load xenpv as late as possible On ARM, we only know that FreeBSD is running on Xen via a device tree node. We have to delay xenpv initialization after the device tree has been fully parsed. --- sys/dev/xen/xenpv.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/sys/dev/xen/xenpv.c b/sys/dev/xen/xenpv.c index 19a8397..d709e4c 100644 --- a/sys/dev/xen/xenpv.c +++ b/sys/dev/xen/xenpv.c @@ -54,7 +54,11 @@ xenpv_identify(driver_t *driver, device_t parent) if (devclass_get_device(xenpv_devclass, 0)) return; - if (BUS_ADD_CHILD(parent, 0, "xenpv", 0) == NULL) + /* + * Use a high order number so xenpv is attached after + * xenpci on HVM guests. + */ + if (BUS_ADD_CHILD(parent, 100, "xenpv", 0) == NULL) panic("Unable to attach xenpv bus."); } -- 2.1.0
