The website should be as much up-to-date as possible. There might be a bunch of legacy content around, but please navigate from the front page, and not from some random links Google decided to index (ie, what wiki?) > Can't figure out how use this toolchain on let's say ubuntu 11.10 with > 3.0 kernels. >From the Download page: https://launchpad.net/~lttng/+archive/ppa Instructions are at that link. > Do we have to use special kernel or not? >From the "LTTng 2.0" page: LTTng 2.0 kernel tracer modules build against a vanilla or distribution kernel, without need for additional patches. > Do user space profiling works on 3.0 kernel after installing lltng > even without restart? The kernel and user-space parts are independent. You do not need to restart before you can start tracing, even with the kernel. > Can we use lttv and eclipse viewers or not ? > Not yet, as the aforementioned note indicates. The previous versions of the viewers were mostly hard-coded to the old trace format. They are being rewritten to be made more generic AND support the new format. These changes are non-trivial, unfortunately.
