Subject: [PATCH v6 0/8] latencystats: improvements to algorithm and test
Date: Wed, 29 May 2024 15:54:37 -0700 [thread overview]
Message-ID: <20240529225732.442539-1-stephen@networkplumber.org> (raw)
In-Reply-To: <20240408195036.182545-1-stephen@networkplumber.org>
Latencystats uses unnecessary floating point and is inaccurate if the number
of cycles per ns is not an integral value. Cleanup the code and add
more tests as well.
v6 - rebase and combine updates to test
Stephen Hemminger (8):
latencystats: replace use of VLA
latencystats: handle fractional cycles per ns
latencystats: do not use floating point
latencystats: fix log messages
latencystats: update include files
latencystats: enforce that unused callback function is NULL
latencystats: add metric for number of samples
test: update to latencystats tests
