An updated oprofile package that fixes one bug and adds two enhancements is 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.
- Previously, OProfile could encounter a buffer overrun in the OProfile daemon. This update modifes oprofiled so that OProfile now checks and reports if the filename is too large for the buffer.
- Previously, the OProfile profiler did not provide the performance monitoring events for the Intel Sandy Bridge processor. This update provides the files for the Intel Sandy Bridge processor specific performance events and adds the code to identify Intel Sandy Bridge processors. Now, OProfile provides Intel Sandy Bridge specific events.
- Previously, the OProfile profiler did not identify some Intel Westmere processors causing OProfile to use the fallback Intel Architected events. Now, OProfile provides Intel Westmere specific events for Intel Westmere-EX processors (model 0x2f).
All OProfile users are advised to upgrade to this updated package which fixes this bug and adds these enhancements.
