Asianux Server 7 for x86_64

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.

For detailed information on changes in this release, see the Asianux Server 7.3 Release Notes linked from the References section.

Users of oprofile are advised to upgrade to these updated packages.

Changes to the oprofile component:

operf now handles kernel event samples for exiting processes without crashing

Previously, Asianux Server kernel 4.14 changed the PID value returned in perf event samples for exiting processes to -1. As a result, the use of -1 by the kernel perf event subsystem conflicted with operf's internal use of -1 as a flag. The flag was used to indicate that initialization work was required to retrieve process information. However, any attempt to retrieve that information caused operf to crash.

This update adjusts the oprofile code to use a different value to flag the process information and as a result, it no longer conflicts with the -1 that is used for exiting processes. (BZ#1561103)

OProfile now identifies and supports all POWER9 processors

Due to a previous change in the cpu field in /proc/cpuinfo, OProfile failed to identify certain versions of POWER9 processors.

This update fixes the powerpc /proc/cpuinfo parser in OProfile to identify all POWER9 processors. (BZ#1569199)
