search for: pirq_guest_unbind

...no shutdown handler (or one that doesn''t do much, because on native this is not causing any problems), the assumption in Xen is violated and the hypervisor crashes. Simply removing the BUG_ON() seems inappropriate, though. But I''m uncertain whether it would be reasonable to call pirq_guest_unbind() instead of the BUG_ON(), and if so, how to properly deal with irq_desc[vector].lock (the immediate idea would be to factor out the locking into a wrapper function, but an alternative would be to use recursive locks, and perhaps there are other possibilities). Thanks for any hints, Jan ________...

Hello everyone, this is the fourth version of the patch series that introduces ARMv7 with virtualization extensions support in Xen. The series allows Xen and Dom0 to boot on a Cortex-A15 based Versatile Express simulator. See the following announce email for more informations about what we are trying to achieve, as well as the original git history: See
