Well, if we reuse Michael's statistics: - 58 drivers call pci_enable_msix() - 24 try a single allocation and then fallback to MSI/LSI - 19 use the loop style allocation - 14 try an allocation, and if it fails retry once ...then I expect most of 19/58 (loop style) could be converted to pcim_enable_msix() and pcim_enable_msix_range() and all of 14/58 (single fallback) should be converted to pcim_enable_msix() users. > tejun -- Regards, Alexander Gordeev agordeev@...hat.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
