On each PCIe link NIC can provide multiple PFs and\nVFs/SFs based on these ones. To provide the unambiguous identification\nof the PCIe function the controller index is added. The full representor\nidentifier consists of three indices - controller index, PF index, and\nVF or SF index (if any).\n\nThis patch introduces controller index to ethdev representor syntax,\nexamples:\n\n[[c#]pf#]vf#: VF port representor/s, example: pf0vf1\n[[c#]pf#]sf#: SF port representor/s, example: c1pf1sf[0-3]\n\nc# is controller(host) ID/range in case of multi-host, optional.\n\nFor user application (e.g. OVS), PMD is responsible to interpret and\nlocate representor device based on controller ID, PF ID and VF/SF ID in\nrepresentor syntax.\n\nSigned-off-by: Xueming Li <xuemingl@nvidia.com>\nAcked-by: Viacheslav Ovsiienko <viacheslavo@nvidia.com>\n---\n config/rte_config.h | 1 +\n lib/librte_ethdev/ethdev_private.c | 12 ++++++++++--\n lib/librte_ethdev/rte_ethdev_driver.h | 4 ++++\n 3 files changed, 15 insertions(+), 2 deletions(-)", "diff": "diff --git a/config/rte_config.h b/config/rte_config.h\nindex a0b5160ff2..23d02d51ef 100644\n--- a/config/rte_config.h\n+++ b/config/rte_config.h\n@@ -58,6 +58,7 @@\n #define RTE_MAX_QUEUES_PER_PORT 1024\n #define RTE_ETHDEV_QUEUE_STAT_CNTRS 16 /* max 256 */\n #define RTE_ETHDEV_RXTX_CALLBACKS 1\n+#define RTE_MAX_MULTI_HOST_CTRLS 4\n \n /* cryptodev defines */\n #define RTE_CRYPTO_MAX_DEVS 64\ndiff --git a/lib/librte_ethdev/ethdev_private.c b/lib/librte_ethdev/ethdev_private.c\nindex f81423ceb8..57473b5a39 100644\n--- a/lib/librte_ethdev/ethdev_private.c\n+++ b/lib/librte_ethdev/ethdev_private.c\n@@ -108,14 +108,22 @@ rte_eth_devargs_process_list(char *str, uint16_t *list, uint16_t *len_list,\n /*\n * representor format:\n * #: range or single number of VF representor - legacy\n- * [pf#]vf#: VF port representor/s\n- * [pf#]sf#: SF port representor/s\n+ * [[c#]pf#]vf#: VF port representor/s\n+ * [[c#]pf#]sf#: SF port representor/s\n */\n int\n rte_eth_devargs_parse_representor_ports(char *str, void *data)\n {\n \tstruct rte_eth_devargs *eth_da = data;\n \n+\tif (str[0] == 'c') {\n+\t\tstr += 1;\n+\t\tstr = rte_eth_devargs_process_list(str, eth_da->mh_controllers,\n+\t\t\t\tð_da->nb_mh_controllers,\n+\t\t\t\tRTE_DIM(eth_da->mh_controllers));\n+\t\tif (str == NULL)\n+\t\t\tgoto err;\n+\t}\n \tif (str[0] == 'p' && str[1] == 'f') {\n \t\teth_da->type = RTE_ETH_REPRESENTOR_PF;\n \t\tstr += 2;\ndiff --git a/lib/librte_ethdev/rte_ethdev_driver.h b/lib/librte_ethdev/rte_ethdev_driver.h\nindex 3bc5c5bbbb..8e04634660 100644\n--- a/lib/librte_ethdev/rte_ethdev_driver.h\n+++ b/lib/librte_ethdev/rte_ethdev_driver.h\n@@ -1203,6 +1203,10 @@ enum rte_eth_representor_type {\n \n /** Generic Ethernet device arguments */\n struct rte_eth_devargs {\n+\tuint16_t mh_controllers[RTE_MAX_MULTI_HOST_CTRLS];\n+\t/** controller/s number in case of multi-host */\n+\tuint16_t nb_mh_controllers;\n+\t/** number of controllers in multi-host controllers field */\n \tuint16_t ports[RTE_MAX_ETHPORTS];\n \t/** port/s number to enable on a multi-port single function */\n \tuint16_t nb_ports;\n", "prefixes": [ "v4", "6/9" ] }
