1.11 -- * Fix compilation with PIC * polling hint now refers to /dev/cdrom instead of /dev/scd0 * fix calculations for systems that vary in power draw proc info * Display mwait usage * fix EOF at input * add --version|-v option * spelling error in tips. 1.10 -- * add the "P" key to show the PIDs of the processes when possible * Add support for reading C-state info via sysfs (Kevin Hilman, Venki Pallipadi) * Show USB suspend statistics of USB devices in "-d" dump mode * Show USB suspend statistics as a low priority hint for busy devices * Add support for using the sysfs power supply class (Donnie Berkholz) * Fix USB suspend suggestion to take semi blacklisted stuff into account * Add support for Intel's 4965 wireless power saving mode * On new enough cpus (and kernel 2.6.25), report which C-states the cpu and bios report/support. 1.9 -- * add support for mac80211 based wireless power saving * improve bluetooth inactivity detection (David Woodhouse) * report USB activity (needs 2.6.24-rc kernel) * support the newly reported interrupt events in 2.6.24-rc 1.8 -- * add suggestion to increase VM writeback timeout * add suggestion to enable INOTIFY in the kernel * fix socket fd leak, found by Nikerabbit on #powertop * Add support for deferrable timers (Scott Lamb) * Add active hint to enable USB autosuspend on Fedora 7 * Show blue color if the cpu is 25% or more busy to indicate that idle wakeups no longer is the nr 1 power causer (Santiago Gala) * merge the -d option from Bill Nottingham (Fedora) to allow automated collection of data 1.7 -- Jun 17th, 2007 * add suggestion to disable TV out * add suggestion to disable Wake-On-Lan for unused ethernet * Show P-states (frequencies) 1.6 -- Jun 8th, 2007 * Add suggestion to rf_kill unused wireless interfaces * Propose killing "sealert"; this is a new thing in F7 that wakes up 10 times per second for no reason * avoid showing the laptop mode hint when on AC - Val Henson * suggest enabling noatime to save disk IO's * suggest enabling SATA AHCI Link powermanagement * suggest enabling the SMP Power Aware Scheduler 1.5 -- May 27th, 2007 * fix resize-corrupts-screen-content bug * add interrupts to the wakeups/second data in the emulated (non-mobile) case * calculate a long term power usage from battery charge deltas; this should help people whos battery doesn't report discharge rates, and also will provide a less noisy datapoint * Add option to use `kill` on some known power hogs if they are actually waking up a lot: - beagle (even latest wakes up 10 times/second when not indexing) - hal (suggest to stop cdrom polling) - gnome-power-manager These only show if these actually wake up the cpu 'a lot'; so if these get fixed then the suggestion will not display. 1.4 -- May 25th, 2007 * use gettext to allow translation (with lots of thanks to the various translators, especially to Benjamin Pineau who showed me how to use gettext tools) * fix bluethooth-checks-cause-autload-of-bluetooth bug * use ncurses (Sebastian Kuzminsky) * rotate through the suggestions randomly, so that all of them will show over time * Fix the CONFIG_SND_AC97_POWER_SAVE check to only report on ac97 hw * report "hidden but suprious" timer ticks (due to missing hpet or lack of NO_HZ) * check for HPET being present; if not suggest user to toggle in BIOS or apply the patch * Some suggestions have become "active", you can press a key to tune it right away. * Add active suggestion to enable AC97 powersave mode at runtime * Add active suggestion to enable wireless powersave mode at runtime * Add active suggestion to enable ondemand 1.3 -- May 21st, 2007 * Add suggestion for CONFIG_SND_AC97_POWER_SAVE * Fix inefficient code for readdir (Vince Pinter) * Highlight the worst offenders in bold (Vince Pinter) * Fix crash when running on 2.4 kernels (Harald Fernengel) * Check fgets() return values (Timom Hoenig @ SuSE) * add suggestion to enable laptop mode (when disabled) * add suggestion to disable bluetooth when unused 1.2 -- May 14th, 2007 * Manpage contributed by Carlo Segre from the Debian project * Fix "shows power usage even on AC" bug, spotted by Steinar Gunderson * Fix for batteries that report mA instead of mW from Friedrich Oslage 1.1 -- May 13th, 2007 * Fix bug that shows "you don't have C-states" on mobile CPUs when the cpu is 100% busy as reported by Friedrich * Cosmetic code cleanups (Lindent) as suggested by David Brownell * Get rid of popen() and the static sized events array (Keith Packard) * Add some more tips for kernel config options based on various reports/feedback * Improve "you are not root so can't get timerstats" message to say that you need to be root rather than that you need to change your kernel config * Make a better effort at locating the kernel .config file * Don't show "please turn CONFIG_FOO off" if the kernel you have doesn't even support CONFIG_FOO (yet) * Show absolute per-second wakeup counts too (multiple requestors) * Add capability to suggest disabling daemons and the like 1.0 -- May 11th, 2007 * Initial Release
