Linux Tools - OProfile Support
The Linux Tools OProfile plugin aims to bring the powerful call profiling capabilities of OProfile to Eclipse, in a manner that is easy to use for developers of any level of experience. Inexperienced users can, with 1 click, determine the parts of their code which use the most time while experienced users of OProfile can perform the same functions they would on the command-line but with a much more rich visualization of the results.
Current StatusIn conjunction with the CDT, the plugin can do the following:
- Launch a local C/C++ application and OProfile simultaneously to start profiling (requires root password to execute OProfile commands)
- Automatically gather OProfile data and display in a tree viewer after a launch
- Launch a local C/C++ application and manually control OProfile via a simple dialog
- Configure OProfile to profile several events simultaneously with as many debug registers as the CPU/OProfile supports
- Configure OProfile to profile relevant shared-libraries and/or kernel modules
- Jump to the line-number of the corresponding source file on a double-click of a sample
- Prompt to save the default session for viewing at a later time
- View the oprofiled log
- One-click launch with sane defaults
- Robust filtering for events/sessions/images
- Code-colourization (similar to EclEmma) for code hotspots
- Comparing two sessions/runs similar to functionality of opreport

Try it outYou can download the plugin from our update site, or check the project plugins out of Git directly from eclipse.org at git://git.eclipse.org/gitroot/linuxtools/org.eclipse.linuxtools.git. You will need all the plugins under oprofile subfolder, and the plugins under the profiling subfolder:
