Subject: [PATCH 1/3] rt-tests: cyclictest: Remove histogram totals
|
|
|
|
The Total: line does not seem to contribute much value, as it should just
|
|
be the number of cycles minus the number of overflows. Unless someone
|
|
complains, remove it to simplify moving to common histogram code.

- Tested in rteval
|
|
- Edited commit message to say "cycles" instead of buckets
