As result deprecation of MSI-X/MSI enablement functions pci_enable_msix() and pci_enable_msi_block() all drivers using these two interfaces need to be updated to use the new pci_enable_msi_range() and pci_enable_msix_range() interfaces.

Hi Rusty et al, Based on recently accepted to the mainline pci_enable_msix_exact() function, I am sending a updated version of the patch. Please, let me know if it does not work for you and you need and incremental update from the previous version. Thanks! -- Regards, Alexander Gordeev agordeev at redhat.com

Hi all, The series is a draft of generic MSI driver that supports PCI and Non-PCI device which have MSI capability. If you're not interested it, sorry for the noise. The series is based on Linux-3.16-rc1. MSI was introduced in PCI Spec 2.2. Currently, kernel MSI driver codes are bonding with PCI device. Because MSI has a lot advantages in design. More and more non-PCI devices want to use
