Telemetry commands are now registered through the dmadev library for the gathering of DSA stats. The corresponding callback functions for listing dmadevs and providing info and stats for a specific dmadev are implemented in the dmadev library.An example usage can be seen below: Connecting to /var/run/dpdk/rte/dpdk_telemetry.v2 {"version": "DPDK 22.03.0-rc2", "pid": 2956551, "max_output_len": 16384} Connected to application: "dpdk-dma" --> / {"/": ["/", "/dmadev/info", "/dmadev/list", "/dmadev/stats", ...]} --> /dmadev/list {"/dmadev/list": [0, 1]} --> /dmadev/info,0 {"/dmadev/info": {"name": "0000:00:01.0", "nb_vchans": 1, "numa_node": 0, "max_vchans": 1, "max_desc": 4096, "min_desc": 32, "max_sges": 0, "capabilities": {"mem2mem": 1, "mem2dev": 0, "dev2mem": 0, ...}}} --> /dmadev/stats,0,0 {"/dmadev/stats": {"submitted": 0, "completed": 0, "errors": 0}} Signed-off-by: Sean Morrissey <[email protected]> Tested-by: Sunil Pai G <[email protected]> Reviewed-by: Bruce Richardson <[email protected]> Reviewed-by: Conor Walsh <[email protected]> --- V5: * move capa_names struct back to function V4: * get capability name from function instead of hardcoded * fix checkpatch warnings V3: * update docs with correct examples * code cleanup and added comments V2: * add device capabilities to info command * no requirement to pass vchan id if the device only has one vchan * minor code cleanup --- doc/guides/prog_guide/dmadev.rst | 24 +++++ doc/guides/rel_notes/release_22_07.rst | 5 + lib/dmadev/meson.build | 2 + lib/dmadev/rte_dmadev.c | 130 +++++++++++++++++++++++++ 4 files changed, 161 insertions(+)
