arch_setup_msi_irq() creates an IRQ on-the-fly from the current descriptor which is being converted to an MSI interrupt using pci_msi_enable(). From that point, the I-pipe might have an obsolete view of the interrupt map. I suspect an I-pipe issue here. -- Philippe. _______________________________________________ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core
