Wizzupuvos: well, I think for -devel maybe it is ok00:20
Wizzup(the register change)00:22
siceloWizzup: did you manage to get your serial jig back?00:30
Wizzupyes00:44
WizzupI am going to test asap for pali, it's on my mind.00:44
buZzok, recalibrated battery twice now , ~1200mAh , not too bad03:35
buZzwonder what that would be with correct min/maxvoltage values ;)03:36
buZznow set cpufreq to 'powersave' governor , wonder if this will influence much :P03:37
buZzseems to go near instantly to '1 day remaining' with sim online when i turn off the screen03:53
freemangordonI wonder if it makes sense to install tlp by default07:49
siceloI think not. Unless tlp gets tweaked for mobile use. iirc it causes serious issues at least on Plasma Mobile10:10
WizzupbuZz: I don't think the governor will matter10:16
buZzits still 'one day' after 6hrs10:17
Wizzupyes, this is to be expected10:17
buZzbut well, maybe we can get that display more detailed some day :P10:17
Wizzupsure we can10:18

buZzyeah, like removing those first 5 lines there :P10:20
sicelofreemangordon: https://blog.bshah.in/2021/12/12/tlp-unintended-side-effects/10:28
buZzthusfar the only downside i saw to 'powersave' instead of 'ondemand' was some more laggish scrolling of screen10:33
WizzupbuZz: ok but this won't be what's giving you more power savings10:34
buZzit does seem to be in 300hz clock more often10:34
WizzupbuZz: pretty sure10:34
buZzmhz*10:34
buZzWizzup: yeah you're probably right :)10:34

sicelotime flies. https://github.com/maemo-leste/droid4-linux/pull/3 has now been open for more than 2 months.14:33
Wizzupsicelo: I think we don't check it regularly, we rely on pings :)15:08
lelMerlijnWajer closed a pull request: https://github.com/maemo-leste/droid4-linux/pull/3 (switch to iio driver for N900 accelerometer (lis302dl))15:08
Wizzupsicelo: building now15:17
WizzupI also added this: https://github.com/maemo-leste/droid4-linux/commit/0fe205dd861abef7a18157f445d8d8c5c643bbab15:17
Wizzupuvos ^^15:17
sicelocool. it'll be in linux 5.19 (except the dts changes, which i haven't sent upstream yet). is it ok to send them now, or i should wait until the iio part is fully merged?15:36
siceloin 5.19 is also a minor bq27xxx change (to remove the EINVALs when battery isn't calibrated). i'm happy sre accepted and already queued it15:37
Wizzupgreat15:42
uvosbuZz: uh the powersave cpufreq gov makes the device be at the lowest clock at all times, thats very mutch not what you want16:30
uvosi gues you want conservative style behavior (stays at low clocks longer), but im going to say that this costs power on omap416:31
uvossince clocking down to 300Mhz is less usefull than going into ret sooner16:31
uvosWizzup: i disagree, its imo not fit even for devel16:32
bencohuvos: well, there has to be "something" for -devel right?16:37
bencohand powersave is probably not worth it yeah16:37
bencohunless you have a very high (non-linear) cost for high freqs16:38
uvosbencoh: imo, devel is mostly for stuff that needs testing, not for stuff thats known broken17:18
uvosbencoh: we do have -expieramental for that17:18
uvosbencoh: and sutch a patch in -expiramental would be fine17:18
uvos(imo)17:18
freemangordonWizzup: I am using tlp on my laptop for years17:29
freemangordonit does wonders to battery life17:30
buZzuvos: not -all- the time, fyi, it does get into higher clocks every now and then17:30
buZzbut yeah, sticks in 300 usually17:30
freemangordonbut yeah, there could be bugs17:31
bencohtlp? hmm, I should have a look at that one17:36
bencohoh, it's basically a mix of powersave+performance17:38
Wizzupfreemangordon: I don't know tlp18:03
Wizzupuvos: oh yeah could have done experimental18:04
uvosbuZz: powersave: When attached to a policy object, this governor causes the lowest frequency, within the scaling_min_freq policy limit, to be requested for that policy.18:13
uvoshttps://www.kernel.org/doc/html/v5.17/admin-guide/pm/cpufreq.html18:13
uvospowersave is lowest freq at all times18:13
uvosif thats not what its doing something is wrong18:13
buZzhmm, thats weird? maybe it switched governor again19:19
