Linux Tools - OProfile Support

Overview

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 Status

In 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

Future Plans

  • Robust filtering for events/sessions/images
  • Code-colourization (similar to EclEmma) for code hotspots
  • Comparing two sessions/runs similar to functionality of opreport
