Three flags are introduced: RTE_BUS_SCAN_UNDEFINED: Configuration is irrelevant for this bus RTE_BUS_SCAN_WHITELIST: Scanning should be limited to declared devices RTE_BUS_SCAN_BLACKLIST: Scanning should exclude only declared devices Signed-off-by: Gaetan Rivet --- lib/librte_eal/common/include/rte_bus.h | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) diff --git a/lib/librte_eal/common/include/rte_bus.h b/lib/librte_eal/common/include/rte_bus.h index 4489d1d..b5d7a88 100644 --- a/lib/librte_eal/common/include/rte_bus.h +++ b/lib/librte_eal/common/include/rte_bus.h @@ -126,6 +126,22 @@ typedef int (*rte_bus_unplug_t)(struct rte_devargs *da); typedef int (*rte_bus_parse_t)(const char *name, void *addr); /** + * Bus scan policies + */ +enum rte_bus_scan_mode { + RTE_BUS_SCAN_UNDEFINED, + RTE_BUS_SCAN_WHITELIST, + RTE_BUS_SCAN_BLACKLIST, +}; + +/** + * A structure used to configure bus operations. + */ +struct rte_bus_conf { + enum rte_bus_scan_mode scan_mode; /**< Scan policy. */ +}; + +/** * A structure describing a generic bus. */ struct rte_bus { @@ -137,6 +153,7 @@ struct rte_bus { rte_bus_plug_t plug; /**< Probe single device for drivers */ rte_bus_unplug_t unplug; /**< Remove single device from driver */ rte_bus_parse_t parse; /**< Parse a device name */ + struct rte_bus_conf conf; /**< Bus configuration */ }; /**
