..._restore_msi_irqs-> PHYSDEVOP_restore_msi hypercall (first mask restore) msix_mask_irq(entry, entry->masked) (second mask restore) So msix_mask_irq call in initial domain call graph needs to be removed. Based on this we can move the restore of the mask in default_restore_msi_irqs which would avoid restoring the invalid mask under Xen. Furthermore this simplifies the API by making everything related to restoring an MSI be in the platform specific APIs instead of just parts of it. After patch, restore call graph under initial domain: pci_reset_function-> pci_restore_s...

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

Pci_dev_msi_enabled() is used to check whether device MSI/MSIX enabled. Refactor this function to suuport checking only device MSI or MSIX enabled.
