| 11:49.24 | badcloud | *for |
| 11:49.30 | lindi- | badcloud: I guess we could port one? |
| 11:49.40 | badcloud | that would be stelar |
| 11:50.18 | badcloud | *stellar |
| 11:50.25 | lindi- | unfortunately at least currently I have other openmoko issues to fix |
| 11:50.49 | lindi- | badcloud: what .34 tree are you using? |
| 11:51.07 | badcloud | hmmm, not sure .34.2 (qtmoko v28.2) |
| 11:51.14 | *** join/#openmoko Openfree (~df@61.170.200.66) |
| 11:51.24 | lindi- | badcloud: so radekp's qtmoko-v28 branch I guess |
| 11:51.31 | badcloud | lindi-: right |
| 11:51.36 | gena2x | badcloud: ah, i just forgot about battery problem. can you describe problem, why do you need special module? |
| 11:51.39 | lindi- | my build machine is offline unfortunately |
| 11:51.58 | badcloud | gena2x: I'm using a Nokia BL-6C battery |
| 11:52.16 | badcloud | gta01-battery module works in v26 |
| 11:52.21 | badcloud | but not with v28 |
| 11:52.31 | lindi- | badcloud: is the module the same? |
| 11:52.33 | gena2x | badcloud: what is definition of 'works'? charging? |
| 11:52.43 | lindi- | smoke? |
| 11:52.57 | badcloud | lindi-: that's the thing. I think the later module is called platform_battery |
| 11:53.04 | badcloud | gena2x: works, charging, yes |
| 11:53.23 | badcloud | gena2x: plus differenciating between charging and only on battery power |
| 11:53.51 | gena2x | badcloud: i just wanted to say that while i were fixing problem with power consumtion, my nokia battery were charging without probelms |
| 11:53.56 | lindi- | badcloud: you mean the module changed its name? |
| 11:53.58 | badcloud | where can I download platform_battery to try it out? |
| 11:54.06 | lindi- | badcloud: it's all in git |
| 11:54.13 | gena2x | badcloud: and i think i did not add anything special to kernel |
| 11:54.24 | badcloud | gena2x: really? |
| 11:54.28 | gena2x | i just connected battery with 2 contacts |
| 11:54.40 | gena2x | without middle one |
| 11:54.55 | badcloud | don't know if I have the proper tools |
| 11:54.58 | radekp | gena2x: it's in git but i have disabled it from config |
| 11:55.13 | gena2x | radekp: any reason? |
| 11:55.33 | radekp | gena2x: because when enabled it was used instead of original openmoko battery driver |
| 11:55.41 | gena2x | badcloud: i can compile kernel for you in few minutes if it is just matter of config |
| 11:55.49 | badcloud | gena2x: hold that thought |
| 11:56.03 | badcloud | radekp: I just installed v28 tarball on my usd |
| 11:56.26 | badcloud | radekp: do I need to put anything else on the fs in order for the module to work? |
| 11:57.12 | radekp | badcloud: we could try compile kernel for you with platform_battery instead of openmoko battery |
| 11:57.22 | radekp | badcloud: as gena2x suggested |
| 11:57.25 | gena2x | radekp: as far as i understand, only ordinary usage difference is ability to see current charge level, so if wrong driver loaded, just can't see what is current charge |
| 11:57.33 | gena2x | radekp: this where question |
| 11:57.38 | gena2x | *were |
| 11:58.06 | badcloud | radekp: I see |
| 11:58.06 | radekp | gena2x: yup i couldnt see current_now and other important sysfs nodes |
| 11:58.28 | radekp | gena2x: do you know how kernel knows which battery driver to select? |
| 11:58.47 | badcloud | couldn't I just dl the module from git and modprobe it? |
| 11:58.53 | gena2x | radekp: no, never tryed dive into battery questions |
| 11:59.17 | radekp | gena2x: strange is that with 2.6.29 it picked the correct driver |
| 11:59.39 | radekp | badcloud: i think the battery driver is compiled in |
| 12:00.29 | gena2x | radekp: actually should be easy to understand this, as it should only on probe level |
| 12:00.42 | badcloud | platform_battery not found... |
| 12:01.04 | gena2x | badcloud: do you want me to compile kernel for you or want to do it on your own? |
| 12:01.11 | badcloud | gena2x: hold on one sec |
| 12:01.15 | gena2x | ok |
| 12:01.20 | badcloud | just located /sys/bus/platform/devices/platform_battery |
| 12:01.32 | badcloud | so why can't I modprobe it |
| 12:02.12 | badcloud | isn't there some command needed to rebuild the module list? |

| 12:02.27 | badcloud | that's the one |
| 12:02.50 | badcloud | $%^& didn't work |
| 12:02.53 | gena2x | but you can avoid it with insmod istead of modprobe. but i am sure this will not help you |
| 12:03.19 | gena2x | if radek told that dumb buttery module disabled it is disabled |
| 12:03.26 | badcloud | I see |
| 12:03.36 | badcloud | I guess I just didn't understand the process |
| 12:04.09 | badcloud | I was just toying again with the idea of upgrading to v28 |
| 12:04.17 | badcloud | but I could reinstall v26 |
| 12:04.42 | badcloud | after ~1 month it doesn't work as well as in the beginning |
| 12:04.54 | gena2x | about my 'method' you can try to use piece of sticky tape to block middle pin on battery and try my method |
| 12:05.25 | gena2x | badcloud: so, want kernel with compiled module now? |
| 12:05.39 | badcloud | gena2x: it's just that? a piece of sticky tape for the middle pin? |
| 12:06.00 | gena2x | badcloud: i think it may work, and should not damage anything |
| 12:06.30 | badcloud | locating some sticky enough tape now |
| 12:07.54 | gena2x | badcloud: but new kernel installation procedure is easy, it should take may be 15 mins |
| 12:08.18 | badcloud | gena2x: since you're here, can you move part of the udfu fs to usd like we did in v26? |
| 12:08.25 | badcloud | such as /usr |
| 12:08.39 | gena2x | badcloud: of course, just copy and make link |
| 12:08.51 | gena2x | badcloud: and add line to fstab |
| 12:08.58 | radekp | gena2x: btw do you remember your patch for high current in suspend bug? the one witch set regulator to always_on=0 |
| 12:09.23 | gena2x | radekp: sure, what's with it? |
| 12:09.26 | radekp | gena2x: i found out that SHR has different patch then qtmoko |

| 12:12.26 | badcloud | gena2x: yeah, it didn't work |
| 12:12.31 | radekp | has to go, bbl |
| 12:12.37 | badcloud | maybe I need another layer...? |
| 12:12.53 | gena2x | radekp: ok, i'll tell Jama about your finding |

| 12:41.44 | badcloud | hold on |
| 12:41.54 | gena2x | it always show it is charging |
| 12:42.33 | gena2x | how do you determine it works? |

| 12:42.46 | *** join/#openmoko Openfree (~df@61.170.200.66) |
| 12:42.51 | badcloud | no, at the battery panel |
| 12:43.01 | badcloud | worked fine |
| 12:43.02 | gena2x | if battery is really charging, it should be determined by dmesg |
| 12:43.20 | gena2x | 'usb curlim to xxx mA' messages |
| 12:43.21 | badcloud | [ 456.020000] pcf50633 0-0073: usb curlim to 0 mA |

| 12:44.20 | gena2x | so, check with taped pin |
| 12:44.32 | badcloud | works in both cases |

| 12:45.10 | gena2x | but i don't know how it should really work |
| 12:45.33 | gena2x | i mean should it indicate that battery is full |
| 12:45.38 | gena2x | or not |
| 12:45.42 | badcloud | I'll flash udfu and see how that works |

| 12:46.38 | gena2x | but dmesg is proper, so it should be charged |
| 12:47.20 | gena2x | so your problem is solved? want compiled kernel? |
| 12:48.20 | lindi- | gena2x: note that usb current limit does not mean that battery is charging |
| 12:48.40 | lindi- | gena2x: and 'om usb charger-limit' is a way to poll usb charger limit, no need to read dmesg |
| 12:48.41 | gena2x | lindi-: any ideas not to check it in better way? |
| 12:49.10 | gena2x | lindi-: except multimeter? |
| 12:49.28 | badcloud | gena2x: I'm going to boot udfu after flashing. most likely it will work there too |
| 12:49.49 | gena2x | lindi-: and i bet if charger limit is 0 you battery is for sure not charging |
| 12:49.54 | lindi- | gena2x: 'om battery consumption' is a reliable way to see if battery is really charging |
| 12:50.06 | badcloud | lindi-: more so than dmesg? |
| 12:50.15 | lindi- | gena2x: true but usb charger-limit of 1000 does not mean that the battery is charging either |

| 12:50.40 | lindi- | gena2x: battery charger-limit |
| 12:50.50 | lindi- | there are two limits |
| 12:50.59 | gena2x | hm. if you have dumb battery |
| 12:51.03 | gena2x | it is not controllable |
| 12:51.12 | gena2x | so charger limit should be enough? |
| 12:51.24 | lindi- | gena2x: you mean 'om usb charger-limit'? |

| 12:51.59 | lindi- | I assume it does |

| 12:52.17 | gena2x | and in case of nokia battery - nothing else |
| 12:52.58 | gena2x | so kernel message about limit should be ebough to judge if we are really charging? |
| 12:53.05 | gena2x | *enough |
| 12:53.13 | lindi- | "om usb charger-limit" is e.g. /sys/class/i2c-adapter/i2c-0/0-0073/pcf50633-mbc/usb_curlim |

| 12:54.37 | lindi- | gena2x: so it could still be possible that "om battery charger-limit" is zero and prevents the battery from charging |
| 12:54.47 | gena2x | so, should be enough to judge if battery is charging. |

| 12:57.04 | gena2x | *enough |

| 12:58.21 | gena2x | lindi-: battery presence is related to charger state |
| 12:58.55 | PaulFertser | gena2x: given some assumptions (the overall system consumption is less than the current, specified in the message; the host is actually capable of providing specified current; the battery is present and works properly), i'd say yes. |
| 12:58.58 | gena2x | lindi-: i meant 'not related of course' |
| 12:59.28 | lindi- | PaulFertser: but if I say 'om battery charger-limit 0' then battery is not charging |

| 13:00.35 | PaulFertser | lindi-: indeed, thanks. |

| 13:03.24 | gena2x | badcloud: so, in case if you really need recompiled kernel it is here:bsdmn.com/openmoko/dumbbatt platform_battery compiled as module. but stick tape to middle contact and check kernel messages. |

| 14:59.41 | gena2x | lindi-: nothing, it is very clear and informative, i just never read it before. nothing is told about kernel of course (except that changing USB limit involves battery limit), and missing 1000mA (which seem somehow working with USB). |
| 15:00.06 | lindi- | yeah 1000 mA indeed works |
| 15:00.16 | lindi- | I just didn't want to advertise it since I was unsure |
| 15:03.06 | gena2x | i think power provider, not power consumer should be responsible for any overloads |
| 15:03.30 | gena2x | so freerunner should consume as much as it can |
| 15:03.40 | gena2x | of course this is guess |
| 15:04.12 | gena2x | but overwise this sounds like bad design than malfulctioning consumer can fire your system |
| 15:04.49 | gena2x | like it happens with n900 charged from freerunner. |

| 15:20.37 | SpeedEvil | Do that, and for example, plugging a OM into a unpowered hub can cause the hard disk that's also plugged in there to reset. |
| 15:21.38 | SpeedEvil | Also, some devices require a reboot to recover after USB overload. |
| 15:23.23 | gena2x | so, hub should recover from overload if you attach 5 hard drives, but can't handle 1 consumer consuming like 5 hard drives? |
| 15:25.52 | SpeedEvil | It recovers - sure. |
| 15:26.26 | SpeedEvil | But you may have corruption on the hard drive, as it's disconnected without syncing. |
| 15:27.37 | gena2x | and what about negotiation? i thought usb protocal has special fields to request power |
| 15:27.44 | gena2x | *protocol |
| 15:28.22 | SpeedEvil | It does. |
| 15:28.37 | gena2x | and this is a way how it should be managed and way to know for provider to prevent overloads |
| 15:28.55 | gena2x | s/to/how to/ |
| 15:28.57 | SpeedEvil | Drawing more than your allocation will cause resets |
| 15:29.08 | SpeedEvil | And on plug-in - the allocation is 100mA |
| 15:29.26 | SpeedEvil | The host has to then configure you to be able to draw more |
| 15:29.41 | SpeedEvil | Also - 500mA is the most a standard port can provide. |
| 15:30.06 | lindi- | SpeedEvil: except in usb 3? |

| 15:33.42 | SpeedEvil | Add a 'high power' class hub that could enable 30V per-port, and most computer related wall-warts just go away. |
| 15:34.22 | gena2x | btw as we have no reports about 1000mA, seem it works everywhere |
