Hi. I'm looking for advice on how a device driver should handle restoring MSI-X following a device reset. Here's my situation: we have an MSI-X-capable device that for various reasons might be reset by the device driver. One of the features of this device is that a reset also wipes out the MSI-X structure in MMIO address space. So this leads to my question: what is the recommended way for the driver to restore MSI-X following such a reset? I suppose one (perhaps naive) way would be to do something like this: free all IRQs pci_disable_msix(); reset device pci_enable_msix() request new IRQs That seems unclean. Is there a better way?
