| 02:59.02 | detule | i got a few sod-s on 3.4, need someone to blame |
| 02:59.49 | jonpry | ugh sod |
| 03:04.31 | detule | made any progress on the droid? |
| 03:12.13 | jonpry | i need a serial cable to do anything |
| 03:12.28 | jonpry | so i ordered one from china. hopefully it will help |
| 03:13.00 | jonpry | i tried search for any available piece of memory to make a ramconsole out of but it appears to all be zeroed by something |
| 03:13.13 | jonpry | and the sram is zeroed by the kernel |
| 03:15.30 | jonpry | might be some kind of gpio led |

| 03:44.24 | detule | how did you search the memory? |
| 03:44.48 | detule | pretty sure i've been using this with no evdev wakelocks |
| 03:51.13 | jonpry | i made a kernel module that i can load |
| 03:52.23 | jonpry | there is a big hole at the end of ram for dsp stuff that i think only gets loaded for video decoding so i ioremap'd it. put some stuff in it, rebooted. all zero's |
| 03:55.02 | jonpry | i suppose its possible that the hole gets zeroed but regular kernel memory doesn't somehow |
| 03:55.34 | jonpry | but that is a can of worms trying to carve out memory live in the kernel |
| 03:57.12 | detule | are there any moto sources out there with ram console addresses? |
| 03:57.42 | jonpry | the source can be compiled with ram console and it generates a hole |
| 03:58.28 | jonpry | also there is some kind of apanic thing i don't understand |
| 03:58.50 | jonpry | like i can blow up a kernel and it will email motorola |
| 03:59.45 | jonpry | but i wonder how worthwhile all that is when it has serial capability |

| 04:04.48 | jonpry | this device tree stuff is also really scary |
| 04:04.56 | jonpry | like all moto phones use the same kernel |
| 04:05.00 | jonpry | with same machtype |
| 04:05.07 | jonpry | and even the same boardfile |
| 04:06.58 | detule | wow they make htc look good |
| 04:07.20 | jonpry | i'm not convinced this is a terrible idea |
| 04:07.44 | jonpry | really they are just antiquating machtype voodoo in exchange for device tree |
| 04:07.49 | detule | sounds like xdandroid all over again and the cluster that was .27 |
| 04:08.07 | detule | i take it back |
| 04:08.25 | jonpry | we could do device tree |
| 04:09.29 | jonpry | all the cool people are doing it |
| 04:10.03 | detule | oh yeah i really have no idea how these dts's work |
| 04:10.34 | jonpry | there is that problem |
| 04:15.16 | detule | so what's the advantage here - less code replication? |
| 04:17.34 | jonpry | something like that. eventually get it to a place where there is no board specific code in the kernel |
| 04:17.50 | jonpry | and a kernel can just run on a phone with a good enough device tree |

| 20:47.17 | jonpry | broke? |
| 20:47.32 | detule | yeah and i don't think it's us |
| 20:48.06 | detule | i get the same sod-like failure with clean android patches, and with our own 3.2/3.3 patches |
| 20:49.52 | jonpry | hrm |
| 20:50.16 | jonpry | some kind of arch/arm mach-msm interaction? |
| 20:51.21 | detule | don't think so i think it something with the process freezer |
| 20:52.35 | jonpry | why is that? |
| 20:52.48 | jonpry | have you pulled a ramconsole from after sod? |
| 20:53.12 | detule | i've pulled maybe 20, i can reproduce it |
| 20:53.38 | jonpry | anything juicy? |
| 20:53.58 | detule | http://pastebin.com/2Mag3jbn |
| 20:54.14 | detule | i can reproduce it if i get on a call |
| 20:54.18 | detule | cover the prox |
| 20:54.22 | detule | (proximity 0 in the log) |
| 20:54.27 | detule | phone goes to sleep |
| 20:54.30 | detule | doesn't wake up |
| 20:54.46 | detule | note at the end of that log |
| 20:55.00 | detule | everything is working as in there are repeated requests for this thing to wake up |
| 20:55.14 | detule | but the kernel is completely unresponsive |
| 20:55.32 | jonpry | yes |
| 20:55.44 | jonpry | so not really an sod |
| 20:56.02 | detule | no |
| 20:56.04 | Alex[sp3dev] | on kovsky/35 the similiar problem was because of mmc, so i had to hack it for wl1251. but it may be anything. you could try ftrace to write the log to sd card although it is not very nice |
| 20:56.37 | jonpry | kernel seems to have woken up |
| 20:56.47 | jonpry | i would blame that evdev time crapola |
| 20:57.11 | detule | well i still haven't patched this thing for embedded sdio -> though wifi is working fine...could that be a problem? |
| 20:57.14 | Alex[sp3dev] | well, it may just spin or wait_event in some place |
| 20:57.24 | Alex[sp3dev] | detule: nope, embedded sdio is deprecated |
| 20:57.27 | jonpry | there is a timesource change in evdev too |
| 20:57.30 | detule | not in our kernel |
| 20:57.35 | jonpry | lol |
| 20:57.52 | Alex[sp3dev] | detule: well, embedded sdio was never needed for bcm4329 |
| 20:58.01 | Alex[sp3dev] | it was for wl1251 which doesn't have cccr/cis registers |
| 20:58.10 | detule | thanks, i suspected that was the case |
| 20:58.52 | detule | [ 493.940000] Restarting tasks ... done. |
| 20:58.53 | detule | <PROTECTED> |
| 20:58.57 | Alex[sp3dev] | either way, i don't know a good way of debugging kernel except inserting printk everywhere around locks/wait_events |
| 20:59.20 | jonpry | not a believer in timesource problem? |
| 20:59.57 | detule | if i knew what it was |
| 21:00.10 | detule | this is with evdev.c from 3.3 |
| 21:00.11 | Alex[sp3dev] | that may be the case, especially if there's some timeout waiting |
| 21:00.32 | Willd | xles: Dang! |
| 21:00.39 | Willd | Err. Wrong. |
| 21:00.39 | Alex[sp3dev] | jonpry: can you imagine how secure nexus is? xloader really didn't check SBL signature and boots any crap i flash |
| 21:00.53 | jonpry | i wish i had that problem |
| 21:01.46 | jonpry | how many pc's would it take to brute force a sha1? |
| 21:02.02 | Willd | Err. Wrong. |

| 21:04.10 | Alex[sp3dev] | but really, isn't omap using some 1024bit rsa? |
| 21:04.44 | detule | here's another log with a different wake_lock http://pastebin.com/QQCaZ6sb .... |
| 21:05.13 | jonpry | not sure. and sbl could use its own method |
| 21:06.25 | Alex[sp3dev] | PM: Device power.0 failed to suspend noirq: error -11 >>> that's strange. on most devices android alarm does return error, but power.0 is something new |
| 21:08.06 | Alex[sp3dev] | that's likely wakelock |
| 21:08.42 | detule | yeah but like, the failure path is somehow polluted |
| 21:09.55 | detule | and i don't get why the active wake lock doesn't show up in "Freezing user space processes" since I am pretty sure that guy also checks "has_wake_lock(" |
| 21:10.53 | jonpry | i could have botched the patches to kernel/power |
| 21:10.58 | jonpry | it would't be the first time |
| 21:11.36 | detule | yeah but i get the same thing with your patches, and with clean android patches....ugh tired of looking at this |

| 21:22.22 | Alex[sp3dev] | i see |
| 21:23.44 | jonpry | and every cracker wanted ics source. i wonder what part of internet traffic was taken up by that stuff |

| 21:32.45 | Cotulla | how is L4 port Alexx/ |
| 21:33.05 | Cotulla | & |
| 21:33.08 | Cotulla | ? |
| 21:45.03 | Alex[sp3dev] | Cotulla: not yet started. that's not the primary goal. for now, it is necessary to finish uboot port (add dfu/fastboot) and write some userland software |
