|Re: [tracecompass-dev] ftrace support and roadmap|
Hi Jerome, Quick question, what do you actually mean by "support for ftrace"?I have not used ftrace much myself, but I have seen demos of the KernelShark tool. From a quick look it seems like something that could be easily re-implemented within Trace Compass, possibly using the shiny new data-driven time graph views.
Basically what would be required is:- A parser for the traces (the "trace-cmd.dat" man page defines that format, right?) - A mapping from events to states (which events cause which states, under which conditions, etc.)
- A mapping from states to colors to put in the viewAlso, just like the Wireshark/pcap parser that was added last summer, the goal wouldn't be to take over or replace Wireshark/KernelShark. But rather, having at least the main features and similar views available in Trace Compass would allow looking at those traces side-by-side with other traces of other types (like other layers in the stack). Which would allow for more advanced use cases.
Would it be something useful, or did you have something else in mind? Cheers, Alexandre On 10/20/2014 06:31 AM, Jerome CORRENOZ wrote:
Hi all, In our team, we're interested by Trace Compass project which seems promising. Is it planned to add the support of ftrace which is the tracing framework for the Linux kernel? More generally, could you please let me know where to get some plans and roadmaps if already available ? Best regards, Jerome
