These attributes are implemented from the information available from rte_eth_dev_data struct. The new APIs are added, to allow applications to trigger IF-MIB attribute initialization and the implementation based on the port id. IF-MIB attributes are allocated in shared memory to support multi process access. For not to expose IF-MIB attributes structs to user, the structs are kept internal. Making use of the metrics library to register attributes names to metrics library and update their values to metrics library by calling rte_metrics_reg_names() and rte_metrics_update_values() respectively. Applications should call rte_metrics_get_values() and rte_metrics_get_names() to view IF-MIB info. The above approach need, making ethdev librray dependent on metrics library. Is this acceptable? Comments are welcome. If not, we can move all the implementation to new library similar to bitrate and latency libraries. With this approach new library needs the access to rte_eth_devices[] to access rte_eth_dev_data. But AFAIK rte_eth_devices[] is not allowed to be accessed outside of PMDs and ethdev layer. Any comments here? Added rte_clock.h with wrapper function for clock_gettime(CLOCK_MONOTONIC). Question: Since ifLastChange and ifDiscontinuityTime IF-MIB attributes implementation should be based on the SysUpTime that is "The time since the network management portion of the system was last reinitialized". Since DPDK doesn't know about the the Network Management Portion, I assume these 2 attributes should not be implemented in DPDK. Please clarify. Looking forward to hear opinions. Signed-off-by: Reshma Pattan --- v3: *Added new file rte_clock.h to provide wrapper for clock_gettime(CLOCK_MONOTONIC). *Used new wrapper function to get the dev start time instead of TSC counter. *Renamed the new struct members. *Update the commit message. *Added a new question and seeking the clarification on the same. v2: Corrected typos and description of the commit message. --- lib/Makefile | 6 +- lib/librte_eal/common/Makefile | 2 +- lib/librte_eal/common/include/rte_clock.h | 68 ++++++++++++ lib/librte_ether/rte_ethdev.c | 172 +++++++++++++++++++++++++++++- lib/librte_ether/rte_ethdev.h | 7 ++ lib/librte_ether/rte_ethdev_pci.h | 1 + mk/rte.app.mk | 2 +- 7 files changed, 252 insertions(+), 6 deletions(-) create mode 100644 lib/librte_eal/common/include/rte_clock.h diff --git a/lib/Makefile b/lib/Makefile index 07e1fd0..aa2be5b 100644 --- a/lib/Makefile +++ b/lib/Makefile @@ -35,6 +35,8 @@ DIRS-y += librte_compat DIRS-$(CONFIG_RTE_LIBRTE_EAL) += librte_eal DIRS-$(CONFIG_RTE_LIBRTE_RING) += librte_ring DEPDIRS-librte_ring := librte_eal +DIRS-$(CONFIG_RTE_LIBRTE_METRICS) += librte_metrics +DEPDIRS-librte_metrics := librte_eal DIRS-$(CONFIG_RTE_LIBRTE_MEMPOOL) += librte_mempool DEPDIRS-librte_mempool := librte_eal librte_ring DIRS-$(CONFIG_RTE_LIBRTE_MBUF) += librte_mbuf @@ -46,7 +48,7 @@ DEPDIRS-librte_cfgfile := librte_eal DIRS-$(CONFIG_RTE_LIBRTE_CMDLINE) += librte_cmdline DEPDIRS-librte_cmdline := librte_eal DIRS-$(CONFIG_RTE_LIBRTE_ETHER) += librte_ether -DEPDIRS-librte_ether := librte_net librte_eal librte_mempool librte_ring +DEPDIRS-librte_ether := librte_net librte_eal librte_mempool librte_ring librte_metrics DEPDIRS-librte_ether += librte_mbuf DIRS-$(CONFIG_RTE_LIBRTE_CRYPTODEV) += librte_cryptodev DEPDIRS-librte_cryptodev := librte_eal librte_mempool librte_ring librte_mbuf @@ -70,8 +72,6 @@ DEPDIRS-librte_ip_frag := librte_eal librte_mempool librte_mbuf librte_ether DEPDIRS-librte_ip_frag += librte_hash DIRS-$(CONFIG_RTE_LIBRTE_JOBSTATS) += librte_jobstats DEPDIRS-librte_jobstats := librte_eal -DIRS-$(CONFIG_RTE_LIBRTE_METRICS) += librte_metrics -DEPDIRS-librte_metrics := librte_eal DIRS-$(CONFIG_RTE_LIBRTE_BITRATE) += librte_bitratestats DEPDIRS-librte_bitratestats := librte_eal librte_metrics librte_ether DIRS-$(CONFIG_RTE_LIBRTE_LATENCY_STATS) += librte_latencystats diff --git a/lib/librte_eal/common/Makefile b/lib/librte_eal/common/Makefile index a5bd108..8dd438a 100644 --- a/lib/librte_eal/common/Makefile +++ b/lib/librte_eal/common/Makefile @@ -40,7 +40,7 @@ INC += rte_string_fns.h rte_version.h INC += rte_eal_memconfig.h rte_malloc_heap.h INC += rte_hexdump.h rte_devargs.h rte_bus.h rte_dev.h rte_vdev.h INC += rte_pci_dev_feature_defs.h rte_pci_dev_features.h -INC += rte_malloc.h rte_keepalive.h rte_time.h +INC += rte_malloc.h rte_keepalive.h rte_time.h rte_clock.h GENERIC_INC := rte_atomic.h rte_byteorder.h rte_cycles.h rte_prefetch.h GENERIC_INC += rte_spinlock.h rte_memcpy.h rte_cpuflags.h rte_rwlock.h diff --git a/lib/librte_eal/common/include/rte_clock.h b/lib/librte_eal/common/include/rte_clock.h new file mode 100644 index 0000000..8b22a37 --- /dev/null +++ b/lib/librte_eal/common/include/rte_clock.h @@ -0,0 +1,68 @@ +/*- + * BSD LICENSE + * + * Copyright(c) 2017-2018 Intel Corporation.
