Hello! I'm having problems getting PCI pass-through to work. This is on a AMD64 system, paravirtualized with xen-hypervisor-4.0-amd64 4.0.0-1~experimental.1, dom0: linux-image-2.6.32-5-xen-amd64 2.6.32-12. From IRC, earlier today: <tschwinge> waldi: Aren't the Debian xen domU-capable kernels supposed to contain the PCI frontend (needed for PCI pass-through)? I'm getting:

...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).

Hi Ingo, Please pull a few more cpus4096 changes. Most are fairly lightweight with the biggest change being to use cpumask_var_t's for the domain and pending_mask cpumask's in irq_desc. It also deals with this cpu_evtchn_mask bss space bump: 65536 +2031616 2097152 +3100% cpu_evtchn_mask(.bss) Everything merges into tip/master cleanly. Thanks!
