Thread-topic: Weird initialization in PPC port
Hi all,
 
In the context of our port on ARM (EmbeddedXEN project),I'm using an initial port from MontaVista which is based upon the PPC port.
I've notice a strange statement in the file arch/ppc/setup.c (initialization time).
 
Right after the creation of the domain 0, there is the following line:
 
dom0->vcpu[0]->cpu_affinity = cpumask_of_cpu(0);
 
But the vcpu pointer is initialized in the construct_domain0() function which is called afterwards.
 
Therefore, the vcpu field is still NULL and leads to an oops.
 
I've noticed that doing the port on ARM, but I wasn't able to test that on a ppc architecture.
 
I'm using xen 3.1.3 (I've noticed that the PPC port has disappeared in 3.3.x)
 
Please could you explain me how it can work?? (I've checked the code for PPC , and I was not able to find a different behavior).
 
Thanks in advance
 
Daniel
