2021-09-08perfmon: add membw-bound bundleRay Kinsella1-1/+1
Added memory bandwidth boundedness bundle, closely related to cache-hierarchy. This bundle works on ICX only, due to an ICX specific counter. Type: improvement Signed-off-by: Ray Kinsella <mdr@ashroe.eu> Change-Id: Id385bd5f4e645ac020774e311c623afb64b79b1e
2021-09-08perfmon: adding support for papi TMAMRay Kinsella1-2/+33
Adding support for Linux papi TMAM on Intel Snowridge. Adds the ability to indicate that a bundle should be thread or node bundle type based on available cpu features (rdpmc support). Type: feature Signed-off-by: Ray Kinsella <mdr@ashroe.eu> Change-Id: Ib871b2644fdb2410fbb580e0d21c3a8e2be13aba

Adding perfmon node TMAM support on ICX. Type: improvement Signed-off-by: Ray Kinsella <mdr@ashroe.eu> Change-Id: I48a9a9ff6a72efc28eaf0cb11ef39fb62cebb126
2021-04-01perfmon: combined set and start command.Ray Kinsella1-2/+1
Original set, start, stop, reset, show etc interface was somewhat cumbersome, we can improve slightly by combining set and start. Type: improvement Signed-off-by: Ray Kinsella <mdr@ashroe.eu> Change-Id: I7b865b2c29d2ab32adbd24d7f8a580da6990bb76
2021-03-16perfmon: add support for raw and timestampsRay Kinsella1-0/+2
Add perfmon plugin support to output raw counter and timestamps, both are useful for debug. Type: improvement Signed-off-by: Ray Kinsella <mdr@ashroe.eu> Change-Id: Ia5a73d1f05e3464c18991c2346f0ed8b7ef63099

2020-07-16misc: add callback hooks and refactor pmcTom Seidenberg1-6/+32
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

2019-01-27perfmon: collect data on selected thread(s)Dave Barach1-0/+3
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 Barach1-5/+9
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.
