| |
Hello,
I was looking at the following code in the file drivers/vfio/pci/vfio_pci_intrs.c:
ret = pci_enable_msix_range(pdev, vdev->msix, 1, nvec); if (ret < nvec) { if (ret > 0) pci_disable_msix(pdev); kfree(vdev->msix); kfree(vdev->ctx); return ret; }
I was wondering what is the point of using a range of 1 .. nvec if there is going to be a failure if the number of allocated irqs is less than nvec?
thanks, julia
