From 9da779c324db87ca340e0eb1259c949874f17bed Mon Sep 17 00:00:00 2001 From: Prarit Bhargava Date: Wed, 25 Oct 2017 09:51:32 -0400 Subject: cpupower: Fix no-rounding MHz frequency output 'cpupower frequency-info -ln' returns kHz values on systems with MHz range minimum CPU frequency range. For example, on a 800MHz to 4.20GHz system the command returns hardware limits: 800000 MHz - 4.200000 GHz The code that causes this error can be removed. The next else if clause will handle the output correctly such that hardware limits: 800.000 MHz - 4.200000 GHz is displayed correctly. [v2]: Remove two lines instead of fixing broken code.

This resulted in a conflict between the two libraries. After looking at how other tools installed libraries, and looking at the perf code in tools/perf it looks like installing to /usr/lib64 for 64-bit arches is the correct thing to do. Checks with 'ldd cpupower' on SLES, RHEL, Fedora, and Ubuntu result in the correct binary AFAICT: [root@testsystem cpupower]# ldd cpupower | grep cpupower libcpupower.so.0 => /lib64/libcpupower.so.0 (0x00007f1dab447000) Commit ac5a181d065d ("cpupower: Add cpuidle parts into library") added a new cpupower library version. On Fedora, executing the cpupower binary then resulted in this error [root@testsystem cpupower]# ./cpupower monitor ./cpupower: symbol lookup error: ./cpupower: undefined symbol: get_cpu_topology 64-bit libraries should be installed to /usr/lib64, and other libraries should be installed to /usr/lib. This code was taken from the perf Makefile.config which supports /usr/lib and /usr/lib64.
