Re: [linuxtools-dev] NexusLite source code.
|
Your feedback is very very very welcome. This is the way our product
gets improved.
Let's say you have a parser for your trace with 3 fields per event.
Your events will be
Timestamp cache hits, cache accesses.
You could actually make a fourth field which would be %hits by adding
another field.
After that, I would suggest looking at the xml charting, it was merged
yesterday, and I have not yet seen it in action, but I will look into it
and get back to you asap.
Thanks for your interest,
Matthew
