Usage Events/s Category Description 2.58 W 0.3 pkts/s Device Network interface: wlan0 (ath10k_pci) 569 mW 100.0% Device USB device: usb-device-04e8-a00a 65.6 mW 6.4 ms/s 18.1 Process [PID 534] /usr/local/bin/enlightenment 26.7 mW 406.3 µs/s 14.6 Timer tick_sched_timer 14.2 mW 101.1 µs/s 8.1 Process [PID 8] [rcu_preempt] 14.0 mW 132.2 µs/s 7.9 kWork gc_worker 8.60 mW 374.2 µs/s 3.9 Interrupt [0] HI_SOFTIRQ 7.54 mW 685.1 µs/s 2.2 Process [PID 331] /usr/lib/xorg-server/Xorg -nolisten tcp vt07 -auth /var/run/slim.auth so basically it's fine. there is some polling of cpu freq and temperature, some battery notifications.... but really its quick wake and sleep as any render will invariably involve deferring the rendering for the next vsync. stracing shows e asleep for most of a second and eeze is forcing a poll every second on the temperature sensor. i unload temperature module and e will stay asleep for 2-3 or 4 secs at a time then wakeup to a battery/power supply event and go check battery status. ymmv based on your acpi dsdt and how often battery acpi events happen, but the wakeups you see above are really only like 1 or 2 per sec. i think it's counting a blocking syscall like a read() of a /sysfs node or a write+read from pipe (vsync event from vsync thread to mainloop), actually strace e with timestamps and see. it may be counting selects that in the loop run "poll to see if events came in while we were reading them" or the thread selects etc. so take that number of wakeups with a grain of salt. FYI i had my GPD pocket 7 (my mini 7" baytrail laptop) run for 22hrs without suspending (screen on lowest brightness level, wifi connected)... e of course running. when e is animating expect a lot of wakeups - at least 2-3 maybe 4x the actual framerate due to the above (the wake it's measured). another sample of battery life: galaxy book 12, 50% brightness with e just idling: The battery reports a discharge rate of 2.29 W The estimated remaining time is 18 hours, 30 minutes Power est. Usage Events/s Category Description 2.57 W 0.5 pkts/s Device Network interface: wlan0 (ath10k_pci) 572 mW 100.0% Device USB device: usb-device-04e8-a00a 50.1 mW 4.9 ms/s 12.8 Process [PID 534] /usr/local/bin/enlightenment 18.1 mW 265.5 µs/s 9.2 Timer tick_sched_timer So... actually look into what is waking things up. fast polling times for gadgets like temp, cpufreq etc. will use more power. temperature if using udev (eeze) can wake up more often. if you have terminals with blinking cursors... that's not going to help much... disable blinking. :) > Thanks, > Marc > -- > "A mouse is a device used to point at the xterm you want to type in" - A.S.R. > Microsoft is to operating systems .... > .... what McDonalds is to gourmet > cooking Home page: http://marc.merlins.org/ | PGP > 1024R/763BE901 > > ------------------------------------------------------------------------------ > Check out the vibrant tech community on one of the world's most > engaging tech sites, Slashdot.org! http://sdm.link/slashdot > _______________________________________________ > enlightenment-users mailing list > enlightenment-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/enlightenment-users > -- ------------- Codito, ergo sum - "I code, therefore I am" -------------- Carsten Haitzler - ras...@rasterman.com ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ enlightenment-users mailing list enlightenment-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/enlightenment-users
