Hello, I''ve previously been successful with Xen4 and VT-d on other systems. I am having trouble getting VT-d passthrough working to a WinXP domain with DX58SO (Q45) motherboard and i7 930 CPU. VT-d is enabled in bios, xm info shows hvm_directio capability, I have iommu=1 set, I have the devices bound to pciback on dom0 cmdline, xm pci-list-assignable-devices shows the devices as

I do not seem to be able to get any where with the power management functions. I have had a look at the xenpm Wiki page, but it hasn''t helped.

...entries that are set to delivery mode SMI. While this seems reasonable if the entry was unmasked, I consider it dubious for masked entries. In Linux, such behavior is benign since when the entry later is being used for some normal interrupt, the old setting is simply overwritten. In Xen, however, ioapic_guest_write() uses the vector field to determine the previous associated IRQ and possibly call remove_pin_at_irq() - this is where we got a report of a hypervisor crash - the BUG() in the first loop of this function triggers. Since I see two ways of fixing this (and perhaps there are more), before creating a...

...3 suspend/resume, as Xen already does it. The more important is to avoid warnings on some platforms which may have uninitialized RTEs to be weird value (like smi mode) but masked. When dom0 saves those entries and then write back later, it''s easy to trigger Xen''s sanity check from ioapic_guest_write.

Now that x86-64 has directly accessible percpu variables, it can also implement the direct versions of these operations, which operate on a vcpu_info structure directly embedded in the percpu area. In fact, the 64-bit versions are more or less identical, and so can be shared. The only two differences are: 1. xen_restore_fl_direct takes its argument in eax on 32-bit, and rdi on 64-bit.
