We are pleased to announce the release of PowerTOP v2.3. This is a maintenance release. About PowerTOP PowerTOP is a Linux tool used to diagnose issues with power consumption and power management. In addition to being a diagnostic tool, PowerTOP also has an interactive mode you can use to experiment with various power management settings, for cases where the Linux distribution has not enabled those settings. PowerTOP reports which system components are most likely to blame for higher-than-needed power consumption, ranging from software applications to active hardware components. Detailed screens are available for CPU C and P states, device activity, and software activity. Highlights * Reduced duplication in CPU code * Improved ARM build support * Various bug fixes and cleanups Thank you to everyone who contributed to this release! Austin Zhang (2): V2: Fix C states and P states presentation issue. Using std::max to handle all such kind of logic Daniel Kahn Gillmor (1): Correct script for tuning wifi power_save with iw Ivan Shapovalov (10): Fix includes: do not include intel_cpus.h inside cpu.h Deduplication: move is_turbo() function to lib Deduplication: move all instances of account_freq() to abstract_cpu::account_freq() Deduplication: remove nhm_cpu::account_freq() almost identical to abstract_cpu::account_freq() Deduplication: remove nhm_{cpu, core, package}::change_effective_frequency() identical to cpu_{linux, core, package}::change_effective_frequency() Deduplication: merge cpu_{core, linux, package}::change_effective_frequency() into abstract_cpu::change_effective_frequency() Deduplication: remove {cpu, nhm}_core::calculate_freq() identical to abstract_cpu::calculate_freq() Deduplication: remove nhm_package::calculate_freq() identical to cpu_package::calculate_freq() Deduplication: properly merge cpu_package::calculate_freq() into abstract_cpu::calculate_freq() Deduplication: merge go_idle()/go_unidle()/change_freq() overrides into abstract_cpu() class Jaroslav Skarvada (1): cpufreq: only try to open files under cpuX Jaroslav Škarvada (2): report: fixed crash when writing report to RO filesystem Do not call abstract_cpu::wiggle for GPU Kristen Carlson Accardi (4): pot update: changes required for transifex due to string change new and modified po files from transifex change version for 2.3 fix issue with string termination Namhyung Kim (4): Use PACKAGE_VERSION for POWERTOP_VERSION process: Get rid of unused dbg_printf_pevent_info() main: 'quiet' option does not take an argument main: Fix output when running workload Paul Menzel (1): src/cpu/cpu.cpp: Fix typo in error message: freque*nc*y Rajagopal Venkat (1): Allow frequency stats when cpuidle is not enabled Sergey Senozhatsky (5): tab_window: null members on construction parameters: fix uninitialized values in param/result getters runtime_pm: register parameters remove csstoh.c measurement: handle multiple batteries in global_time_left() Thomas Waldecker (2): csstoh.sh shell script fixes cross compiling issues csstoh shell-script for cross-compiling Project Details URL: https://01.org/powertop Download: https://01.org/powertop/downloads/2012/PowerTOP-v2.2 Mailing list: Discussions about PowerTOP occur on the PowerTOP at lists.01.org mailing list.
