Since genirq, MSI interrupts have their irq_chip descriptor managed by the IO-APIC support. What remains to be tested is the masking/unmasking code, which is still implemented by the msi driver; unfortunately I have no PCI-Express hw at hand anymore, so I can't test CONFIG_PCI_MSI properly. At first sight, the issue Mathias raised looks like an out-of-bound array reference indexed on an unexpectedly large IRQ value; this would be quite a dumb bug, but the only way to check that is with proper hw. -- Philippe. _______________________________________________ Xenomai-help mailing list [email protected] https://mail.gna.org/listinfo/xenomai-help
