Hi, I'm using FSO-unstable with 2.6.28 (from people.openmoko.org/andy Jan 7 Image). What I've noticed is that with the moredrivers kernel I seem to get sporadic wakeups from suspend. For eg - I never got a full night's suspend. And since I needed to keep auto suspend disabled since FSO suspends even when plugged in to a USB cable, I would generally wake with the battery pretty much discharged. I was reading about the power consumption issues with WiFi, and so made a small script to switch off WiFi containing iwconfig eth0 txpower off wmiconfig -i eth0 --wlan disable ifconfig eth0 down (probably don't need this)
And last night I had an uninterrupted suspend from 22:51 to 05:53! But I Lost about 13% power during this time (95% to 82%). Now, that sets me wondering about two things :- 1. Were most of my wakeups because of WiFi? I should have kept track of the reason - but I didn't. Will do so now. But, Isn't WiFi supposed to be off by default? 2. Why is the phone consuming 13% power in 7 hrs? Seems rather high if I look at from the perspective of simple nokia phones. Powertop says Wakeups-from-idle per second : 523.6 interval: 5.0 s Top causes for wakeups: 39.0% (204.0) <interrupt> : s3c-mci 38.3% (200.6) <interrupt> : S3C2410 Timer Tick 19.2% (100.4) ksdioirqd/mmc0 : schedule_timeout (process_timeout) 1.8% ( 9.6) python : schedule_hrtimeout_range (hrtimer_wakeup) 0.6% ( 3.0) <interrupt> : s3c2410_udc 0.2% ( 1.2) Xglamo : hrtimer_start (it_real_fn) 0.2% ( 1.0) gsm0710muxd : schedule_hrtimeout_range (hrtimer_wakeup) 0.2% ( 1.0) enlightenment : schedule_hrtimeout_range (hrtimer_wakeup) 0.2% ( 1.0) watchdog/0 : start_rt_bandwidth (sched_rt_period_timer) 0.1% ( 0.4) <kernel core> : schedule_delayed_work_on (delayed_work_timer_fn) I remember reading something about a tickless kernel patch. Has that been incorporated? Any chances of incorporating CONFIG_CPU_FREQ_GOV_ONDEMAND, CONFIG_ACPI_BATTERY,HPET, USB autosuspend, CONFIG_NO_HZ etc in the kernels? Of course I understand that the kernel is still in active development - just wanted to check if these are on the list :-) -- View this message in context: http://n2.nabble.com/Isn%27t-Wifi-supposed-to-be-off-by-default--tp2154678p2154678.html Sent from the Openmoko Kernel mailing list archive at Nabble.com.
