2020-07-16misc: add callback hooks and refactor pmcTom Seidenberg1-16/+17
Callbacks for monitoring and performance measurement: - Add new callback list type, with context - Add callbacks for API, CLI, and barrier sync - Modify node dispatch callback to pass plugin-specific context - Modify perfmon plugin to keep PMC samples local to the plugin - Include process nodes in dispatch callback - Pass dispatch function return value to callback Type: refactor Signed-off-by: Tom Seidenberg <tseidenb@cisco.com> Change-Id: I28b06c58490611e08d76ff5b01b2347ba2109b22
2019-12-17perfmon: fix per-worker data initializationBenoît Ganne1-6/+0
When perfmon_init is called at initialization time worker threads are not created yet and vec_len(vlib_mains) returns 1. Initialize per-worker data when the number of workers is known, when enabling data collection instead. Type: fix Change-Id: I36887cc7b2a3e88d9728d3cd7262d9b1c968dd3c Signed-off-by: Benoît Ganne <bganne@cisco.com>

- Make plugin descriptions more consistent so the output of "show plugin" can be used in the wiki. Change-Id: I4c6feb11e7dcc5a4cf0848eed37f1d3b035c7dda Signed-off-by: Dave Wallace <dwallacelf@gmail.com>

2019-01-27perfmon: collect data on selected thread(s)Dave Barach1-3/+25
Add missing pre-input node runtime fork and refork code. unix-epoll-input runs on all threads; each instance needs its own runtime stats. Change-Id: I16b02e42d0c95f863161176c4bb9f9917bef809d Signed-off-by: Dave Barach <dave@barachs.net>
2019-01-24perfmon plugin: 2-way parallel stat collectionDave Barach1-21/+41
As a FUD reduction measure, this patch implements 2-way parallel counter collection. Synthetic stat component counter pairs run at the same time. Running two counters (of any kind) at the same time naturally reduces the aggregate time required by an approximate factor-of-2, depending on whether an even or odd number of stats have been requested. I don't completely buy the argument that computing synthetic stats such as instructions-per-clock will be inaccurate if component counter values are collected sequentially. Given uniform traffic pattern, it must make no difference. As the collection interval increases, the difference between serial and parallel component counter collection will approach zero, see also the Central Limit theorem.

2018-12-17Improve perfmon json table pickerDave Barach1-22/+90
Built a tool to chew up https://download.01.org/perfmon/mapfile.csv, and output a table in this format: typedef struct { u8 model; u8 stepping; u8 has_stepping; char *filename; } file_by_model_and_stepping_t; static const file_by_model_and_stepping_t fms_table [] = { /* model, stepping, stepping valid, file */ { 0x2E, 0x0, 0, "NehalemEX_core_V2.json" }, { 0x1E, 0x0, 0, "NehalemEP_core_V2.json" }, <snip> { 0x55, 0x5, 1, "cascadelakex_core_v1.00.json" }, { 0x55, 0x6, 1, "cascadelakex_core_v1.00.json" }, { 0x55, 0x7, 1, "cascadelakex_core_v1.00.json" }, <snip> Change-Id: Ie0e8a7e851799e9d060b966047745039c066ec7b Signed-off-by: Dave Barach <dave@barachs.net>
