Subject: [PATCH 0/8] rtla usage improvements
Date: Wed, 24 Apr 2024 16:36:49 +0200 [thread overview]
Message-ID: <cover.1713968967.git.bristot@kernel.org> (raw)
Hi
These are some changes I have accumulated in the last
weeks. Mostly improving the tool's user experience.
- On timerlat top, remove an extra \n that was breaking
the output.
- Replace \t with ' ' on the auto analysis, fixing some
copy & paste.
- On timerlat top, do not print TTY formatting characters when
the output is not sent to a terminal, because they break the
output.
- on timerlat top and hist, add a summary with the overall results.
For instance, the minimum value for all CPUs, the overall average
and the maximum value from all CPUs.
- Add a --warm-up <seconds> option, allowing the workload to run for
<seconds> before starting to collect results.
- Add a --trace-buffer-size option, allowing the user to set the
tracing buffer size. This is mainly useful for reducing the trace
file.
- Make the user-space threads the default choice, also adding the
a -k option, allowing the user to switch to kerne-threads.
