[ Upstream commit 2de7fb60a4740135e03cf55c1982e393ccb87b6b ] Building cpupower with -fno-common in CFLAGS results in errors due to multiple definitions of the 'cpu_count' and 'start_time' variables. ./utils/idle_monitor/snb_idle.o:./utils/idle_monitor/cpupower-monitor.h:28: multiple definition of `cpu_count'; ./utils/idle_monitor/nhm_idle.o:./utils/idle_monitor/cpupower-monitor.h:28: first defined here ... ./utils/idle_monitor/cpuidle_sysfs.o:./utils/idle_monitor/cpuidle_sysfs.c:22: multiple definition of `start_time'; ./utils/idle_monitor/amd_fam14h_idle.o:./utils/idle_monitor/amd_fam14h_idle.c:85: first defined here The -fno-common option will be enabled by default in GCC 10.

The cpupower package consists of the following elements: requirements ------------ On x86 pciutils is needed at runtime (-lpci). For compilation pciutils-devel (pci/pci.h) and a gcc version providing cpuid.h is needed. For both it's not explicitly checked for (yet). libcpupower ---------- "libcpupower" is a library which offers a unified access method for userspace tools and programs to the cpufreq core and drivers in the Linux kernel. This allows for code reduction in userspace tools, a clean implementation of the interaction to the cpufreq core, and support for both the sysfs and proc interfaces [depending on configuration, see below]. compilation and installation ---------------------------- make su make install should suffice on most systems. It builds libcpupower to put in /usr/lib; cpupower, cpufreq-bench_plot.sh to put in /usr/bin; and cpufreq-bench to put in /usr/sbin. If you want to set up the paths differently and/or want to configure the package to your specific needs, you need to open "Makefile" with an editor of your choice and edit the block marked CONFIGURATION. THANKS ------ Many thanks to Mattia Dongili who wrote the autotoolization and libtoolization, the manpages and the italian language file for cpupower; to Dave Jones for his feedback and his dump_psb tool; to Bruno Ducrot for his powernow-k8-decode and intel_gsic tools as well as the french language file; and to various others commenting on the previous (pre-)releases of cpupower.
