Hi Alex, I've confirmed that the patch works as intended for the 8086:270c device, and negative tested the warning by commenting out the device's entry in known_bogus_vf_intx_pin. For what it's worth, my positive test case - launching a QEMU VM with a VFIO-owned 0x270c device - did not trigger the warning. This is because the change to vfio_pci_config.c caused QEMU to read a PCI_INTERRUPT_PIN value of 0, and so didn't execute a codepath that calls vfio_pci_get_irq_count(). Instead, I used a simple C program that calls the VFIO_DEVICE_GET_IRQ_INFO ioctl for negative testing. Also, there's one typo in the comment: 'quite' -> 'quiet' Tested-by: Gage Eads <gage.e...@intel.com> Thanks, Gage _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
