1.201. papi

An updated papi package that fixes a bug and provides an enhancement is now available for Red Hat Enterprise Linux 6.
PAPI (Performance Application Programming Interface) is a software library that provides access to the processor's performance-monitoring hardware. This allows developers to track performance-related events, such as cache misses, instructions retired, and clock cycles, to better understand the performance issues of the software.
Bug Fix
When using PAPI on the AMD family 0x15 processors, the "papi_avail" utility returned that the number of hardware performance counters was four. However, for these processors, the number of hardware performance counters is six. This update implements support for the additional two hardware counters.
Previously, PAPI did not handle the new event mappings for the AMD Opteron 6000-series processor and some newer AMD family 10h processors. Due to this, PAPI did not recognize or work with these processors. This update adds the lists of the new events and PAPI recognizes and works with the processors correctly.
PAPI users are advised to upgrade to this updated package, which fixes this bug and adds this enhancement.
