4.134. oprofile
Updated oprofile packages that add two enhancements are now available for Red Hat Enterprise Linux 5.
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.
Enhancements
- BZ#713667
- Previously, the OProfile profiler did not provide the performance monitoring events for the Intel Core i3, i5, i7 and other processors formerly code named "Sandy Bridge". This update provides the files specific to the performance events of processors formerly code named "Sandy Bridge" and adds support for identification of these processors.
- BZ#643476
- Previously, the OProfile profiler did not identify the processors based on the Intel Xeon Processor E56XX, L56XX, W36XX and X56XX families. As a result, OProfile used the fallback Intel Architected events. With this update, OProfile provides the events specific to the processors based on the Intel Xeon Processor E56XX, L56XX, W36XX and X56XX families.
All OProfile users are advised to upgrade to these updated packages, which add these enhancements.
