These allow a list of rawdev devices and xstats for a rawdev port to be queried. An example usage, with ioat rawdev driver instances, is shown below: Connecting to /var/run/dpdk/rte/dpdk_telemetry.v2 {"pid": 66100, "version": "DPDK 20.05.0-rc0", "max_output_len": 16384} --> / {"/": ["/", "/ethdev/link_status", "/ethdev/list", "/ethdev/xstats", \ "/info", "/rawdev/list", "/rawdev/xstats"]} --> /rawdev/list {"/rawdev/list": [0, 1, 2, 3, 4, 5]} --> /rawdev/xstats,0 {"/rawdev/xstats": {"failed_enqueues": 0, "successful_enqueues": 0, \ "copies_started": 0, "copies_completed": 0}} Signed-off-by: Bruce Richardson Signed-off-by: Ciara Power --- v2: Renamed stats to xstats for device specific stats. --- lib/librte_rawdev/Makefile | 5 +++ lib/librte_rawdev/meson.build | 5 +++ lib/librte_rawdev/rte_rawdev.c | 81 ++++++++++++++++++++++++++++++++++ 3 files changed, 91 insertions(+) diff --git a/lib/librte_rawdev/Makefile b/lib/librte_rawdev/Makefile index 7dd1197dcd..ccf68f60ec 100644 --- a/lib/librte_rawdev/Makefile +++ b/lib/librte_rawdev/Makefile @@ -11,6 +11,11 @@ CFLAGS += -O3 CFLAGS += $(WERROR_FLAGS) LDLIBS += -lrte_eal +ifeq ($(CONFIG_RTE_LIBRTE_TELEMETRY),y) +CFLAGS += -DALLOW_EXPERIMENTAL_API +LDLIBS += -lrte_telemetry +endif + # library source files SRCS-y += rte_rawdev.c diff --git a/lib/librte_rawdev/meson.build b/lib/librte_rawdev/meson.build index a20fbdc048..3a0ea2a293 100644 --- a/lib/librte_rawdev/meson.build +++ b/lib/librte_rawdev/meson.build @@ -3,3 +3,8 @@ sources = files('rte_rawdev.c') headers = files('rte_rawdev.h', 'rte_rawdev_pmd.h') + +if dpdk_conf.has('RTE_LIBRTE_TELEMETRY') + allow_experimental_apis = true + deps += ['telemetry'] +endif diff --git a/lib/librte_rawdev/rte_rawdev.c b/lib/librte_rawdev/rte_rawdev.c index b6f1e1c779..61fe29110c 100644 --- a/lib/librte_rawdev/rte_rawdev.c +++ b/lib/librte_rawdev/rte_rawdev.c @@ -29,6 +29,9 @@ #include #include #include +#ifdef RTE_LIBRTE_TELEMETRY +#include +#endif #include "rte_rawdev.h" #include "rte_rawdev_pmd.h" @@ -544,9 +547,87 @@ rte_rawdev_pmd_release(struct rte_rawdev *rawdev) return 0; } +#ifdef RTE_LIBRTE_TELEMETRY +static int +handle_dev_list(const char *cmd __rte_unused, + const char *params __rte_unused, + char *buffer, int buf_len) +{ + int used = 0; + int i; + + used = rte_tel_json_empty_array(buffer, buf_len, used); + for (i = 0; i < rawdev_globals.nb_devs; i++) + if (rte_rawdevices[i].attached == RTE_RAWDEV_ATTACHED) + used = rte_tel_json_add_array_int(buffer, buf_len, used, + rte_rawdevices[i].dev_id); + + return used; +} + +static int +handle_dev_xstats(const char *cmd __rte_unused, + const char *params, + char *buffer, int buf_len) +{ + uint64_t *rawdev_xstats; + struct rte_rawdev_xstats_name *xstat_names; + int dev_id, num_xstats, i, ret; + int used = 0; + unsigned int *ids; + + if (params == NULL || strlen(params) == 0 || !isdigit(*params)) + return -1; + + dev_id = atoi(params); + if (!rte_rawdev_pmd_is_valid_dev(dev_id)) + return -1; + + num_xstats = xstats_get_count(dev_id); + if (num_xstats < 0) + return -1; + + /* use one malloc for names, stats and ids */ + rawdev_xstats = malloc((sizeof(uint64_t) + + sizeof(struct rte_rawdev_xstats_name) + + sizeof(unsigned int)) * num_xstats); + if (rawdev_xstats == NULL) + return -1; + xstat_names = (void *)&rawdev_xstats[num_xstats]; + ids = (void *)&xstat_names[num_xstats]; + + ret = rte_rawdev_xstats_names_get(dev_id, xstat_names, num_xstats); + if (ret < 0 || ret > num_xstats) { + free(rawdev_xstats); + return -1; + } + + for (i = 0; i < num_xstats; i++) + ids[i] = i; + + ret = rte_rawdev_xstats_get(dev_id, ids, rawdev_xstats, num_xstats); + if (ret < 0 || ret > num_xstats) { + free(rawdev_xstats); + return -1; + } + + used = rte_tel_json_empty_obj(buffer, buf_len, used); + for (i = 0; i < num_xstats; i++) + used = rte_tel_json_add_obj_u64(buffer, buf_len, used, + xstat_names[i].name, rawdev_xstats[i]); + + free(rawdev_xstats); + return used; +} +#endif + RTE_INIT(librawdev_init_log) { librawdev_logtype = rte_log_register("lib.rawdev"); if (librawdev_logtype >= 0) rte_log_set_level(librawdev_logtype, RTE_LOG_INFO); +#ifdef RTE_LIBRTE_TELEMETRY + rte_telemetry_register_cmd("/rawdev/list", handle_dev_list); + rte_telemetry_register_cmd("/rawdev/xstats", handle_dev_xstats); +#endif } -- 2.17.1
