Updated oprofile packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
OProfile is a system-wide profiler for Linux systems. The profiling runs transparently in the background and profile data can be collected at any time. OProfile uses the hardware performance counters provided on many processors, and can use the Real Time Clock (RTC) for profiling on processors without counters.
The oprofile packages have been upgraded to upstream version 0.9.7, which provides a number of bug fixes and enhancements over the previous version. (BZ#739142
Under certain circumstances, the "opannotate" and "opreport" commands reported no results. With this update, this problem has been fixed so that these commands work as expected.
All OProfile users are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
