Im trying to port minix to xen(2.0.7 atm) and Im having problems getting the tasks running in ring 2 to call interrupts in ring 1. I have hypervisor_callback working for when interrupts occur from ring 1. It just calls iretd, and everything is fine.
My problem is when i call
int LEVEL1_VECTOR
from ring 2. I get the following error:
(XEN) (file=extable.c, line=71) Pre-exception: fc53a962 -> fc53aa34
(XEN) (file=traps.c, line=566) GPF (0000): fc53aa49 -> fc506d22
And hypervisor_callback never seems to get called.
Regards
Ivan
