**** BEGIN LOGGING AT Tue Feb 15 02:59:57 2022 Feb 15 09:25:51 is it feasible to apply security patches to fremantle kernel? Feb 15 09:33:52 if they can apply to the kernel sauce ;-) Feb 15 09:41:54 you could always try, but fremantle runs a 2.6.28 kernel from 11y ago, so ... Feb 15 09:42:05 wait, 12~13yo even Feb 15 09:42:22 o.O Feb 15 09:42:38 doesnt fremantle run recent kernels? Feb 15 09:42:43 erm Feb 15 09:42:47 nvm, mind barf Feb 15 09:43:21 cssu runs a patched kernel, some fixes were merged over time, but even then you'd have the same issues trying to apply recent patches Feb 15 09:44:54 maemo-leste runs an almost-mainline kernel ("almost" because of pvr and a few pending patches) Feb 15 09:45:06 and support is getting pretty good these days :) Feb 15 10:00:29 is power management still messy? Feb 15 10:03:27 it should be much better than, say, half a year ago Feb 15 10:04:13 It might not be on-par with fremantle yet though, but iirc it's pretty close Feb 15 10:04:25 really? what changed? Feb 15 10:05:25 AFAIR: work was done on the OFF mode, and there was something about proactive memory compaction waking up the device more than necessary Feb 15 10:06:28 does it still empty the entire battery? Feb 15 10:06:35 ? Feb 15 10:07:01 last time it emptied the entire battery when discharging Feb 15 10:07:20 turning the device on again was painful Feb 15 10:07:43 you mean, under the trickle charge threshold? Feb 15 10:07:59 (ie "deep" discharge) Feb 15 10:08:08 yes Feb 15 10:09:00 I think this could happen with fremantle as well, except that fremantle's bme would poweroff way before that happens Feb 15 10:09:54 but if you replace bme with its opensource counterpart (kernel driver + some userspace script iirc) I think you'd have the same issue as in leste Feb 15 10:10:50 ~bme Feb 15 10:11:07 I don't remember what cssu uses nowadays, I'm not certain opensource battery management was pushed to cssu-stable, it might be only in -devel (and maybe -testing) Feb 15 10:11:29 https://wiki.maemo.org/N900_Software_BME Feb 15 10:13:21 I think that page lacks info on the final replacement solution but apart from that it looks pretty detailed and accurate Feb 15 10:16:11 yeah so there's still pm work to do in mainline kernel, it does enter off mode with some patches but some drivers keep it awake Feb 15 10:16:16 it's not clear which parts do Feb 15 10:17:29 can one have this bme thing on leste? Feb 15 10:18:40 the closed-source one you mean? I highly doubt it, and a better solution would be to just poweroff device at 10~20% instead of letting it reach close-to-empty state Feb 15 10:19:48 mce has this already Feb 15 10:19:54 (on leste) Feb 15 10:20:01 configurable you mean? Feb 15 10:20:21 or a hardcoded 10~20%? Feb 15 10:25:11 there is some hardcoded voltage limit I think **** ENDING LOGGING AT Wed Feb 16 02:59:56 2022
