A SF netdev supports eswitch representation offload similar to existing PF and VF representors. To support SF representor, this patch introduces new devargs syntax: sf#: new SF port representor/s, example: sf[0-3], sf2 Signed-off-by: Xueming Li --- doc/guides/prog_guide/poll_mode_drv.rst | 1 + lib/librte_ethdev/ethdev_private.c | 14 +++++++++++--- lib/librte_ethdev/rte_ethdev_driver.h | 1 + 3 files changed, 13 insertions(+), 3 deletions(-) diff --git a/doc/guides/prog_guide/poll_mode_drv.rst b/doc/guides/prog_guide/poll_mode_drv.rst index 979a2bab9d..831d620c8d 100644 --- a/doc/guides/prog_guide/poll_mode_drv.rst +++ b/doc/guides/prog_guide/poll_mode_drv.rst @@ -377,6 +377,7 @@ parameters to those ports. -a DBDF,representor=vf0 -a DBDF,representor=vf[0,4,6,9] -a DBDF,representor=vf[0-31] + -a DBDF,representor=sf[0-1023] Note: PMDs are not required to support the standard device arguments and users should consult the relevant PMD documentation to see support devargs. diff --git a/lib/librte_ethdev/ethdev_private.c b/lib/librte_ethdev/ethdev_private.c index 54f565ca37..551a43738a 100644 --- a/lib/librte_ethdev/ethdev_private.c +++ b/lib/librte_ethdev/ethdev_private.c @@ -96,6 +96,7 @@ rte_eth_devargs_process_list(char *str, uint16_t *list, uint16_t *len_list, * representor format: * #: range or single number of VF representor - legacy * vf#: VF port representor/s + * sf#: SF port representor/s */ int rte_eth_devargs_parse_representor_ports(char *str, void *data) @@ -103,10 +104,17 @@ rte_eth_devargs_parse_representor_ports(char *str, void *data) struct rte_eth_devargs *eth_da = data; int ret; - /* Parse vf# or number # alone implies VF */ - eth_da->type = RTE_ETH_REPRESENTOR_VF; - if (str[0] == 'v' && str[1] == 'f') + eth_da->type = RTE_ETH_REPRESENTOR_NONE; + /* Parse vf# and sf#, number # alone implies VF */ + if (str[0] == 'v' && str[1] == 'f') { + eth_da->type = RTE_ETH_REPRESENTOR_VF; str += 2; + } else if (str[0] == 's' && str[1] == 'f') { + eth_da->type = RTE_ETH_REPRESENTOR_SF; + str += 2; + } else { + eth_da->type = RTE_ETH_REPRESENTOR_VF; + } ret = rte_eth_devargs_process_list(str, eth_da->representor_ports, ð_da->nb_representor_ports, RTE_MAX_ETHPORTS); if (ret < 0) diff --git a/lib/librte_ethdev/rte_ethdev_driver.h b/lib/librte_ethdev/rte_ethdev_driver.h index b66a955b18..086d64223a 100644 --- a/lib/librte_ethdev/rte_ethdev_driver.h +++ b/lib/librte_ethdev/rte_ethdev_driver.h @@ -1197,6 +1197,7 @@ rte_eth_switch_domain_free(uint16_t domain_id); enum rte_eth_representor_type { RTE_ETH_REPRESENTOR_NONE, /* not a representor */ RTE_ETH_REPRESENTOR_VF, /* representor of VF */ + RTE_ETH_REPRESENTOR_SF, /* representor of SF */ }; /** Generic Ethernet device arguments */ -- 2.25.1
