Functional aspects of the API or data-structure will remain same. +* pci: Several exposed functions are misnamed. + The following functions are deprecated starting from v17.11 and are replaced: + + - ``eal_parse_pci_BDF`` replaced by ``rte_pci_bdf_parse`` + - ``eal_parse_pci_DomBDF`` replaced by ``rte_pci_dbdf_parse`` + - ``rte_eal_compare_pci_addr`` replaced by ``rte_pci_addr_cmp`` + + The functions are only renamed. Their behavior is not affected. + * ethdev: Tx offloads will no longer be enabled by default in 17.11. Instead, the ``rte_eth_txmode`` structure will be extended with bit field to enable each Tx offload. diff --git a/lib/librte_eal/common/eal_common_pci.c b/lib/librte_eal/common/eal_common_pci.c index f8962896c6..2230e0995c 100644 --- a/lib/librte_eal/common/eal_common_pci.c +++ b/lib/librte_eal/common/eal_common_pci.c @@ -106,7 +106,7 @@ get_u8_pciaddr_field(const char *in, void *_u8, char dlm) int -eal_parse_pci_BDF(const char *input, struct rte_pci_addr *dev_addr) +rte_pci_bdf_parse(const char *input, struct rte_pci_addr *dev_addr) { const char *in = input; @@ -124,7 +124,13 @@ eal_parse_pci_BDF(const char *input, struct rte_pci_addr *dev_addr) } int -eal_parse_pci_DomBDF(const char *input, struct rte_pci_addr *dev_addr) +eal_parse_pci_BDF(const char *input, struct rte_pci_addr *dev_addr) +{ + return rte_pci_bdf_parse(input, dev_addr); +} + +int +rte_pci_dbdf_parse(const char *input, struct rte_pci_addr *dev_addr) { const char *in = input; unsigned long val; @@ -148,6 +154,12 @@ eal_parse_pci_DomBDF(const char *input, struct rte_pci_addr *dev_addr) return 0; } +int +eal_parse_pci_DomBDF(const char *input, struct rte_pci_addr *dev_addr) +{ + return rte_pci_dbdf_parse(input, dev_addr); +} + void rte_pci_device_name(const struct rte_pci_addr *addr, char *output, size_t size) @@ -159,8 +171,8 @@ rte_pci_device_name(const struct rte_pci_addr *addr, } int -rte_eal_compare_pci_addr(const struct rte_pci_addr *addr, - const struct rte_pci_addr *addr2) +rte_pci_addr_cmp(const struct rte_pci_addr *addr, + const struct rte_pci_addr *addr2) { uint64_t dev_addr, dev_addr2; @@ -180,6 +192,13 @@ rte_eal_compare_pci_addr(const struct rte_pci_addr *addr, return 0; } +int +rte_eal_compare_pci_addr(const struct rte_pci_addr *addr, + const struct rte_pci_addr *addr2) +{ + return rte_pci_addr_cmp(addr, addr2); +} + void pci_name_set(struct rte_pci_device *dev) { diff --git a/lib/librte_eal/common/include/rte_pci.h b/lib/librte_eal/common/include/rte_pci.h index a366f3f54c..9ac19d5bed 100644 --- a/lib/librte_eal/common/include/rte_pci.h +++ b/lib/librte_eal/common/include/rte_pci.h @@ -253,6 +253,22 @@ TAILQ_HEAD(mapped_pci_res_list, mapped_pci_resource); * @return * 0 on success, negative on error. */ +int rte_pci_bdf_parse(const char *input, struct rte_pci_addr *dev_addr); + +/** + * @deprecated + * Utility function to produce a PCI Bus-Device-Function value + * given a string representation.
