[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v5 6/9] PCI: Expose pci_load_saved_state for public consumption.
We have the pci_load_and_free_saved_state, and pci_store_saved_state but are missing the functionality to just load the state multiple times in the PCI device without having to free/save the state. This patch makes it possible to use this function.
