B.9. Changes in OProfile

Red Hat Developer Toolset 2.0 is distributed with OProfile 0.9.8, which provides a number of bug fixes and feature enhancements over the Red Hat Enterprise Linux system version and the version included in Red Hat Developer Toolset 1.1. Below is a comprehensive list of new features in this release.

B.9.1. Changes Since Red Hat Developer Toolset 1.1

The following features have been added since the release of OProfile included in Red Hat Developer Toolset 1.1:
  • A new command line utility, operf, has been added. This utility can be executed by a non-root user and can be used to collect profiling data.

    Important

    The operf utility relies on a kernel feature that is currently not available in Red Hat Enterprise Linux 5. Consequently, this utility only works and is supported on Red Hat Enterprise Linux 6.
  • OProfile now supports Intel processors code-named Ivy Bridge.

B.9.2. Changes Since Red Hat Enterprise Linux 5.9

The following features have been added since the release of OProfile included in Red Hat Enterprise Linux 5.9:
  • OProfile now supports AMD family11h, family12h, family14h, and AMD family15h processors.
  • Generation of XML output has been corrected.
  • Handling of the --session-dir command line option has been improved and a possible buffer overflow in the XML generator has been fixed.
