* cpupower: Better interface for accessing AMD pci registersThomas Renninger2012-03-034-23/+32
| | | | | | | | | | | | | | | AMD's BKDG (Bios and Kernel Developers Guide) talks in the CPU spec of their CPU families about PCI registers defined by "device" (slot) and func(tion). Assuming that CPU specific configuration PCI devices are always on domain and bus zero a pci_slot_func_init() func which gets the slot and func of the desired PCI device passed looks like the most convenient way. This also obsoletes the PCI device id maintenance.

* cpupower: use man(1) when calling "cpupower help subcommand"Dominik Brodowski2011-08-1911-228/+86

* cpupower: Make monitor command -c/--cpu awareThomas Renninger2011-08-151-0/+8
| | | | | | | | | | | | | | | | | | | | | | This allows for example: cpupower -c 2-4,6 monitor -m Mperf |Mperf PKG |CORE|CPU | C0 | Cx | Freq 0| 8| 4| 2.42| 97.58| 1353 0| 16| 2| 14.38| 85.62| 1928 0| 24| 6| 1.76| 98.24| 1442 1| 16| 3| 15.53| 84.47| 1650 CPUs always get resorted for package, core then cpu id if it could get read out (or however you name these topology levels...). Still this is a nice way to keep the overview if a test binary is bound to a specific CPU or if one wants to show all CPUs inside a package or similar. Still missing: Do not measure not available cores to reduce the overhead and achieve better results.

* cpupower: Better detect offlined CPUsThomas Renninger2011-08-155-4/+66
| | | | | | | | | | | | Before, checking for offlined CPUs was done dirty and it was checked whether topology parsing returned -1 values. But this is a valid case on a Xen (and possibly other) kernels. Do proper online/offline checking, also take CONFIG_HOTPLUG_CPU option into account (no /sys/devices/../cpuX/online file).

* cpupower: Do not show an empty Idle_Stats monitor if no idle driver is availableThomas Renninger2011-08-151-1/+1

* cpupower: mperf monitor - Use TSC to calculate max frequency if possibleThomas Renninger2011-08-152-48/+131
| | | | | | | | | Which makes the implementation independent from cpufreq drivers. Therefore this would also work on a Xen kernel where the hypervisor is doing frequency switching and idle entering.

* cpupower: Do detect IDA (opportunistic processor performance) via cpuidThomas Renninger2011-07-294-41/+9
| | | | | | | | | | | | | | | | | | IA32-Intel Devel guide Volume 3A - 14.3.2.1 ------------------------------------------- ... Opportunistic processor performance operation can be disabled by setting bit 38 of IA32_MISC_ENABLES. This mechanism is intended for BIOS only. If IA32_MISC_ENABLES[38] is set, CPUID.06H:EAX[1] will return 0. Better detect things via cpuid, this cleans up the code a bit and the MSR parts were not working correctly anyway.

* cpupower: Show Intel turbo ratio support via ./cpupower frequency-infoThomas Renninger2011-07-294-17/+95
| | | | | | | | | | | | | | | This adds the last piece missing from turbostat (if called with -v). It shows on Intel machines supporting Turbo Boost how many cores have to be active/idle to enter which boost mode (frequency). Whether the HW really enters these boost modes can be verified via ./cpupower monitor.

* cpupowerutils - cpufrequtils extended with quite some featuresDominik Brodowski2011-07-2972-0/+14417
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>
