This patch introduces optional 'pf' section to representor devargs syntax, examples: representor=pf0vf0 - single VF representor representor=pf[0-1]sf[0-1023] - SF representors from 2 PFs PF type representor is supported by using standalone 'pf' section: representor=pf1 - PF representor Signed-off-by: Xueming Li Acked-by: Viacheslav Ovsiienko Acked-by: Thomas Monjalon Acked-by: Andrew Rybchenko --- doc/guides/prog_guide/poll_mode_drv.rst | 3 +++ lib/librte_ethdev/ethdev_private.c | 19 +++++++++++++++++-- lib/librte_ethdev/rte_ethdev.h | 1 + 3 files changed, 21 insertions(+), 2 deletions(-) diff --git a/doc/guides/prog_guide/poll_mode_drv.rst b/doc/guides/prog_guide/poll_mode_drv.rst index 063a4680df..0d4ac77a7c 100644 --- a/doc/guides/prog_guide/poll_mode_drv.rst +++ b/doc/guides/prog_guide/poll_mode_drv.rst @@ -382,6 +382,9 @@ parameters to those ports. -a DBDF,representor=sf[1,3,5] -a DBDF,representor=sf[0-1023] -a DBDF,representor=sf[0,2-4,7,9-11] + -a DBDF,representor=pf1vf0 + -a DBDF,representor=pf[0-1]sf[0-127] + -a DBDF,representor=pf1 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 13c191192e..35a57c56ec 100644 --- a/lib/librte_ethdev/ethdev_private.c +++ b/lib/librte_ethdev/ethdev_private.c @@ -118,8 +118,9 @@ 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 + * [pf#]vf#: VF port representor/s + * [pf#]sf#: SF port representor/s + * pf#: PF port representor/s * * Examples of #: * 2 - single @@ -131,6 +132,14 @@ rte_eth_devargs_parse_representor_ports(char *str, void *data) { struct rte_eth_devargs *eth_da = data; + if (str[0] == 'p' && str[1] == 'f') { + eth_da->type = RTE_ETH_REPRESENTOR_PF; + str += 2; + str = rte_eth_devargs_process_list(str, eth_da->ports, + ð_da->nb_ports, RTE_DIM(eth_da->ports)); + if (str == NULL || str[0] == '\0') + goto done; + } if (str[0] == 'v' && str[1] == 'f') { eth_da->type = RTE_ETH_REPRESENTOR_VF; str += 2; @@ -138,11 +147,17 @@ rte_eth_devargs_parse_representor_ports(char *str, void *data) eth_da->type = RTE_ETH_REPRESENTOR_SF; str += 2; } else { + /* 'pf' must followed by 'vf' or 'sf'. */ + if (eth_da->type == RTE_ETH_REPRESENTOR_PF) { + str = NULL; + goto done; + } eth_da->type = RTE_ETH_REPRESENTOR_VF; } str = rte_eth_devargs_process_list(str, eth_da->representor_ports, ð_da->nb_representor_ports, RTE_DIM(eth_da->representor_ports)); +done: if (str == NULL) RTE_LOG(ERR, EAL, "wrong representor format: %s\n", str); return str == NULL ? -1 : 0; diff --git a/lib/librte_ethdev/rte_ethdev.h b/lib/librte_ethdev/rte_ethdev.h index 26b5e109c3..9cd519bf59 100644 --- a/lib/librte_ethdev/rte_ethdev.h +++ b/lib/librte_ethdev/rte_ethdev.h @@ -1513,6 +1513,7 @@ enum rte_eth_representor_type { RTE_ETH_REPRESENTOR_NONE, /**< not a representor. */ RTE_ETH_REPRESENTOR_VF, /**< representor of Virtual Function. */ RTE_ETH_REPRESENTOR_SF, /**< representor of Sub Function. */ + RTE_ETH_REPRESENTOR_PF, /**< representor of Physical Function. */ }; /**
