Thank you very much for the report.

This config (and all the other configs in the reports about implicit declaration of function 'pci_msix_can_alloc_dyn') has: # CONFIG_PCI_MSI is not set
Resulting in:
> drivers/vfio/pci/vfio_pci_intrs.c: In function 'vfio_msi_set_vector_signal': >>> drivers/vfio/pci/vfio_pci_intrs.c:427:21: error: implicit declaration of function 'pci_msix_can_alloc_dyn' [-Werror=implicit-function-declaration] > 427 | if (msix && pci_msix_can_alloc_dyn(vdev->pdev)) > | ^~~~~~~~~~~~~~~~~~~~~~ > cc1: some warnings being treated as errors >
because include/linux/pci.h is missing a stub for pci_msix_can_alloc_dyn() when CONFIG_PCI_MSI is not set. I'll send a separate fix for that.
