[PATCH]vtd: Fix for irq bind failure after PCI attaching 32 times
vtd: Fix for irq bind failure after PCI attaching 32 times
Originally when detaching a PCI device, pirq_to_emuirq and pirq_to_irq are freed via hypercall do_physdev_op. Now in function pt_irq_destroy_bind_vtd, duplicated logic is added to free pirq_to_emuirq, but not pirq_to_irq. This causes do_physdev_op fail to free both emuirq and irq. After attaching a PCI device for 32 times, irq resources

Issue about domU missing interrupt

In summary, this is the suspicious log:
(XEN) vmsi.c:122:d32767 Unsupported delivery mode 3
I''ve checked the code in question and found that mode 3 is an ''reserved_1''
mode.
I want to trace down the source of this
