Subject: [PATCH v5 0/3] Add lcore poll busyness telemetry
Date: Fri,  2 Sep 2022 16:58:24 +0100	[thread overview]
Message-ID: <20220902155827.79076-1-kevin.laatz@intel.com> (raw)
In-Reply-To: <24c49429394294cfbf0d9c506b205029bac77c8b.1657890378.git.anatoly.burakov@intel.com>

Currently, there is no way to measure lcore polling busyness in a passive
way, without any modifications to the application. This patchset adds a new
EAL API that will be able to passively track core polling busyness. As part
of the set, new telemetry endpoints are added to read the generate metrics.

---
v5:
  * Fix Windows build
  * Make lcore_telemetry_free() an internal interface
  * Minor cleanup

v4:
  * Fix doc build
  * Rename timestamp macro to RTE_LCORE_POLL_BUSYNESS_TIMESTAMP
  * Make enable/disable read and write atomic
  * Change rte_lcore_poll_busyness_enabled_set() param to bool
  * Move mem alloc from enable/disable to init/cleanup
  * Other minor fixes

v3:
  * Fix missing renaming to poll busyness
  * Fix clang compilation
  * Fix arm compilation

v2:
  * Use rte_get_tsc_hz() to adjust the telemetry period
  * Rename to reflect polling busyness vs general busyness
  * Fix segfault when calling telemetry timestamp from an unregistered
    non-EAL thread.
  * Minor cleanup
