RHEA-2015:2030 - Product Enhancement Advisory

Topic

New devtoolset-4-oprofile packages are now available as a part of Red Hat
Developer Toolset 4.0 for Red Hat Enterprise Linux.

Description

OProfile is a low-overhead, system-wide profiler that uses the performance
monitoring hardware on the processor to retrieve information about the kernel
and executables on the system. The devtoolset-4-oprofile packages provide the
Red Hat Developer Toolset version of OProfile.

This enhancement update adds the devtoolset-4-oprofile packages to Red Hat
Developer Toolset 4.0 for Red Hat Enterprise Linux. These packages include
OProfile 1.1.0, which is the latest stable release of OProfile. It provides a
number of bug fixes and enhancements over the version included in Red Hat
Developer Toolset 3.1, for example:

• The deprecated "opcontrol" and "oprof_start" commands have been removed from

OProfile 1.1.0. The "operf" command should be used in their place. The
"opreport" command is still used to analyze data stored in the oprofile_data/
directory by the operf tool.

• Support for new Intel processors, such as 6th Generation Intel Core

Processors, Intel Xeon Processor D, and Airmont, has been added.

• Fixes have been included to avoid dropping samples from Java programs using

Just-In-Time (JIT) translation due to use of anonymous hugepages and changes in
the anonymous page mappings.

(BZ#1224359)

All users who require devtoolset-4-oprofile are advised to install these new
packages.
