cpupowerutils - cpufrequtils extended with quite some features CPU power consumption vs performance tuning is no longer limited to CPU frequency switching anymore: deep sleep states, traditional dynamic frequency scaling and hidden turbo/boost frequencies are tied close together and depend on each other. The first two exist on different architectures like PPC, Itanium and ARM, the latter (so far) only on X86. On X86 the APU (CPU+GPU) will only run most efficiently if CPU and GPU has proper power management in place. Users and Developers want to have *one* tool to get an overview what their system supports and to monitor and debug CPU power management in detail. The tool should compile and work on as many architectures as possible. Once this tool stabilizes a bit, it is intended to replace the Intel-specific tools in tools/power/x86 Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

.TH CPUPOWER\-INFO "1" "22/02/2011" "" "cpupower Manual"
.SH NAME
cpupower\-info \- Shows processor power related kernel or hardware configurations
.SH SYNOPSIS
.ft B
.B cpupower info [ \-b ] [ \-s ] [ \-m ]
.SH DESCRIPTION
\fBcpupower info \fP shows kernel configurations or processor hardware
registers affecting processor power saving policies.
Some options are platform wide, some affect single cores. By default values
of core zero are displayed only. cpupower --cpu all cpuinfo will show the
settings of all cores, see cpupower(1) how to choose specific cores.
.SH "SEE ALSO"
Options are described in detail in:
cpupower(1), cpupower-set(1)
