Steven,
RTLA:
Specific for timerlat:
- Improves the output of timerlat top by adding a missing \n,
and by avoiding printing color-formatting characters where
they are translated to regular characters.
- Improves timerlat auto-analysis output by replacing '\t'
with spaces to avoid copy-and-paste issues when reporting
problems.
- For timerlat, make the user-space (-u) option the default,
as it is the most complete test. Add a -k option to use
the in-kernel workload.
- 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.
- timerlat hist was printing initial values (i.e., 0 as max,
and ~0 as min) if the trace stopped before the first Ret-User
event. This problem was fixed by printing the " - "
no value string to the output if that was the case.
For all RTLA tools:
- 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 for -t option. This option is mainly
useful for reducing the trace file. Now rtla depends on
libtracefs >= 1.6.
- Fix the -t [trace_file] parsing, now it does not require
the '=' before the option parameter, and better handles the
multiple ways a user can pass the trace_file.txt
