| 02:46.33 | detule | jonpry, samsung galaxy 3 - coming likely both on at&t and sprint |
| 02:47.04 | jonpry | w/ keyboard? |
| 02:47.20 | detule | no, no kbd |
| 02:49.11 | jonpry | i kind of want a kbd |
| 02:49.28 | detule | i should give you my rhod
you will learn there is life without one |
| 02:51.59 | jonpry | no cli w/o keyboard |
| 02:52.19 | detule | it will likely come with 2gb ram |
| 02:52.43 | jonpry | rhod is a tad too slow for good cli. but my next phone i think will be fast enough |
| 02:52.49 | detule | i just hope sprint doesn't cripple the gsm radio ( i think 8960 has a both cdma and gsm radios) |
| 02:53.39 | jonpry | droid4? |
| 02:54.40 | detule | sprint doesnt carry those
. |
| 02:54.58 | jonpry | i'm wondering if the chroot problem can be caused without chroot. like exec /rfs/bin/sh. or execve |
| 02:56.01 | jonpry | verizon only i guess |
| 02:57.01 | detule | need to figure out if chroot is the only syscall that fails |
| 02:57.23 | jonpry | it doesn't fail |
| 02:58.09 | jonpry | just the running of busybox fails |
| 02:58.58 | detule | what's the first thing in rootfs init |
| 02:59.17 | jonpry | doesn't in particular matter |
| 02:59.24 | jonpry | #!/bin/sh is what does it |
| 02:59.54 | detule | sure about that? not /bin/mount -o remount,rw / / |
| 03:00.14 | jonpry | yeah the interpreter is the first line |
| 03:00.33 | jonpry | and you can change the initrd to do chroot /rfs /bin/sh and it will still fail |
| 03:08.46 | jonpry | well i have determined code at the program counter has become corrupted somehow |
| 03:09.03 | jonpry | code at LR is intact |
| 03:11.27 | jonpry | code that is supposed to be at 0010EAF4 is somehow located at f5ef4 |
| 03:11.53 | jonpry | so wtf! |
| 03:14.07 | detule | hm
not sure what changed between 3.3 and 3.4 that would be causing this |
| 03:14.24 | jonpry | its a serious bug |
| 03:14.35 | detule | what toolchain are you compiling this with |
| 03:14.46 | jonpry | 2010q3 |
| 03:15.02 | jonpry | i have no evidence yet but i suspect it is execve |
| 03:15.15 | jonpry | either that or memory management is just totally fubar |
| 03:15.24 | detule | maybe we need 2011q3 |
| 03:15.31 | detule | (i've been trying 2010 too) |
| 03:15.43 | jonpry | worth a try i guess |

| 15:28.32 | Franck78 | yes |

| 15:29.18 | Cotulla | u talk about MAC address right? |
| 15:29.36 | Franck78 | yes, I found it in NAND (hd2) |
| 15:29.44 | Franck78 | wifi and btooth |
| 15:30.22 | Franck78 | confirmed by 'reading' spl |
| 15:32.31 | Cotulla | hm |
| 15:32.46 | Cotulla | but SPL can read it for MFG test? did u compare it with WM65 one? |
| 15:33.01 | Cotulla | AFAIK it read from the nand block after SPL |
| 15:33.09 | Cotulla | is it? |
| 15:33.44 | Franck78 | spl read this block too. |
| 15:34.24 | Franck78 | it also write when nothing is found. |
| 15:34.57 | Cotulla | so u suggest to add it as ATAG to MAGLDR? |
| 15:35.26 | Franck78 | precily what what sais by Rick |
| 15:35.40 | Franck78 | a new tag ! |
| 15:35.44 | Cotulla | yeah |
| 15:35.58 | Cotulla | and in WP7 too should be |

| 15:41.43 | Franck78 | except if your are able to write a full 'radio' code ? |
| 15:41.58 | Cotulla | but anyway what kind of answer u are waiting? "heyy, it's possible & easy"? |
| 15:42.12 | reactor16 | just we can redirect gsm packet from rf and debug it on pc |
| 15:43.05 | reactor16 | there an option in the lg optimus series wich can handle that example using phone as gps dongle or bluetooth ..ect |
| 15:43.37 | Franck78 | Cotulla, Rick95 wants to reverse magldr. I told him to ask you the source. He tolds me, no way, too much dangerous ! |
| 15:44.08 | Cotulla | I know . . . and? instead of doing new things peoples wanna to clone everything |
| 15:44.35 | Franck78 | and it is waste of time... |
| 15:44.41 | Cotulla | and I always was clear - MAGLDR is closed source and it's normal |
| 15:44.52 | Cotulla | it's normal that some software is closed source. |
| 15:44.55 | reactor16 | that why manufacture keep playing with sim registration away from us |
| 15:45.51 | reactor16 | they manufacture chips that do that automaticaly and give us small api's to manage sim record and turn radio on/off . |
| 15:45.52 | Franck78 | I don't understand the need for 'lk' ! |
| 15:46.12 | marc1706 | it makes the leo look more like a native android device :P |
| 15:46.45 | Cotulla | and why leo must looks more like a native andoird device? |
| 15:46.52 | reactor16 | what about openmoko ! |
| 15:47.12 | Cotulla | in my eyes it's totally different - it should looks like XDA community did it. not HTC and etc. |

| 15:50.12 | jonpry | chroot causes memory corruption somehow |
| 15:50.34 | marc1706 | since the hd2's kernel is older I'd say fix the leo's major boot issue with post-.35 kernels first :D |
| 15:50.39 | Franck78 | Cotulla, why spl3.03 + magldr do not work ? |
| 15:50.56 | Cotulla | it's loaded to disabled memory |
| 15:51.05 | jonpry | nah |
| 15:51.07 | Cotulla | spl3.03 only support 448 Mb cuz it's for Europe |

| 15:51.33 | Cotulla | what kind of corruption? |

| 15:52.05 | Cotulla | hm is it stable effect? |

| 19:19.57 | jonpry | hi detule |
| 19:20.20 | detule | hey jonpry, no luck with the new toolchain |
| 19:20.50 | jonpry | i got it to chroot under certain circumstance |
| 19:22.05 | jonpry | wtf lol |
| 19:22.30 | jonpry | so i put a exec /rfs/bin/sh in initrd |
| 19:22.33 | jonpry | which works |
| 19:23.07 | detule | ok |
| 19:23.14 | jonpry | then i can type chroot rfs and it seems to succeed. i can't get it to boot because there is no / key though |
| 19:24.05 | detule | that's so very strange |
| 19:25.22 | jonpry | so i'm guessing it just can't chroot if pid 1 is doing the chroot |
| 19:26.04 | detule | let me look at the fs/ commits again |
| 19:26.11 | jonpry | ubuntu must be doing something similar with there initrd |
| 19:26.22 | jonpry | i guess maybe they use pivot root |

| 20:15.28 | Cotulla | yes it's why it sucks |

| 20:18.19 | Cotulla | so |
| 20:18.44 | Cotulla | the most intersting thing |
| 20:18.52 | Cotulla | that select () in windows is not really compatible |
| 20:18.56 | Cotulla | with unix one |
| 20:20.33 | Alex[sp3dev] | why? i don't think posix says it must support >64 sockets |
| 20:20.46 | Cotulla | it seems events can come in other order and etc |
| 20:20.55 | Cotulla | like two events together and etc |
| 20:21.05 | Cotulla | or all zeros doesn't work |
| 20:21.12 | Cotulla | when u didn't call FD_SET at all |
| 20:21.37 | Cotulla | it should be a problem because there was no events |
| 20:21.44 | Cotulla | so they made separate functions for everything |
| 20:22.00 | Cotulla | it's more logical to assign events for something |
| 20:22.04 | Cotulla | and wait for them isn't it? |
| 20:23.26 | Alex[sp3dev] | well, yes and no. posix and linux kernel do not have any kind of object and HANDLEs, so all i/o functions use file descriptor instead. i think epoll does what you want. |
| 20:26.32 | Alex[sp3dev] | well, i once tried to make a crappy attempt at using epoll to see what it is http://pastebin.com/iWL6LEie . basically it's like an advanced select, with a better interface and you can set level or edge triggers |

| 20:30.03 | Alex[sp3dev] | here's a good overview of select alternatives http://www.kegel.com/c10k.html. in most cases it is probably good to use libev like chromium does. unless your aim is to get to know how select works |
| 20:30.49 | Cotulla | that standards from 1980 |
| 20:30.50 | Cotulla | out dated |
| 20:30.55 | Cotulla | WinSocks from 199X |
| 20:31.01 | Cotulla | also should be outdated I think |
| 20:31.43 | Alex[sp3dev] | stuff doesn't get outdated just because time goes by. APIs get deprecated when hardware changes |
| 20:32.25 | Alex[sp3dev] | i mean, you don't like unix, i don't like windows but there are tons of software for both platforms so you cannot just take one API and make everyone use it |
| 20:33.12 | Cotulla | 64 was enough |
| 20:33.24 | Cotulla | I don't like attitude |
| 20:34.00 | Alex[sp3dev] | what exactly |
| 20:34.46 | Cotulla | like make the second arg of fopen as text string |

| 20:35.12 | Cotulla | or all that poll epoll efuckmenowpollbutiamnotpresentin1.26 |

| 20:35.31 | Alex[sp3dev] | it is |
| 20:35.35 | Alex[sp3dev] | it is just posix, not C |
| 20:35.36 | Cotulla | or ever select() without ability to break call |
| 20:35.44 | Cotulla | good to know |

| 20:36.31 | JC__ | I was struggling with accelerometer in whitestone... Trying to follow the instruccions of jonpry and detule |
| 20:36.43 | Alex[sp3dev] | well, you can kill the process doing select. seems logical - select is intended to wait indefinitely.. unless you specify timeout |
| 20:37.04 | Alex[sp3dev] | jonpry: has pivot_root not worked forever? why do you want to change to chroot? |
| 20:37.20 | jonpry | our initrd uses switch_root |

| 22:04.05 | JC__ | Ok... |
| 22:04.13 | JC__ | So no this ksc_client |
| 22:04.19 | detule | yes you need ksc_client |
| 22:04.20 | JC__ | Right?? |
| 22:04.28 | JC__ | Ohhhh |
| 22:04.31 | JC__ | shettt |
| 22:04.57 | JC__ | May be Changing this ksc_client=i2c_new_dummy(client->adapter, 0x67); |
| 22:05.13 | detule | no |
| 22:05.37 | detule | before you start changing things, parse through the file and try and understand what each thing is accomplishing |
| 22:06.12 | JC__ | Exactly... I was going to say I need read more in that file |
| 22:06.31 | JC__ | Ill be in touch... Thx man |
| 22:07.29 | detule | np... |
| 22:08.07 | detule | i mean jonpry or Alex can probably write it with their eyes closed (even I), but the idea i think is -> it's a pretty good opportunity to learn something |
| 22:08.57 | Alex[sp3dev] | JC__: i'd assume you should use some get drvdata call like in kovsky. but if leds work, leave it as is |
| 22:11.01 | detule | jonpry, pviot_root ftw? |
| 22:26.08 | fakker | privet |
| 22:29.58 | jonpry | detule, yeah i think so |
| 22:30.10 | jonpry | it still didn't work quite right though |
| 22:32.17 | Cotulla | privet |
| 22:36.07 | jonpry | false alarm. all systems fail |
| 22:37.13 | jonpry | i think this might work though exec /rfs/bin/sh -c "chroot /rfs /init" |
| 22:37.19 | Cotulla | still that? |
| 22:37.27 | jonpry | yup |
| 22:37.34 | Cotulla | maybe take another version |
| 22:37.53 | jonpry | we have all other versions |
| 22:41.53 | Cotulla | I mean another kernel version |
| 22:41.58 | Cotulla | maybe this one not working on ARM? |
| 22:42.52 | jonpry | we have ported every kernel version since .39 |
| 22:44.49 | detule | i started indiscriminantly reverting korg patches to fs/ |
| 22:45.43 | jonpry | that exec line does get the party started |
| 22:45.50 | jonpry | but we lose control in init.android |
| 22:46.11 | jonpry | [ 15.010000] init.android: unhandled page fault (11) at 0xffffffe0, code 0x01f |
| 22:46.57 | jonpry | shouldn't that be a vector? |
| 22:48.00 | Cotulla | no |
| 22:48.08 | Cotulla | vectors not there I think |
| 22:48.14 | Cotulla | or maybe there is jumps |
| 22:48.41 | jonpry | high page is not vectors? |
| 22:49.05 | Alex[sp3dev] | should be vectors. well, copy of them. so, it dies at exec syscall? |
| 22:49.42 | Alex[sp3dev] | jonpry: do you know the exact place in kernel where it fails? |
| 22:49.43 | jonpry | it runs init.android with some modifications to initrd |
| 22:49.53 | jonpry | it doesn't fail anywhere in the kernel |
| 22:50.12 | jonpry | userspace exhibits strange behavior |
| 22:50.29 | Alex[sp3dev] | tried some other binaries like debian? |
| 22:50.34 | jonpry | like code rearrangement |
| 22:50.53 | jonpry | i can get this to happen with nothing but a static busybox |
| 22:51.00 | Alex[sp3dev] | how |
| 22:51.24 | jonpry | by running chroot from the busybox to itself |
| 22:51.56 | jonpry | second busybox will have its code segment reorganized |
| 22:52.24 | Alex[sp3dev] | well, maybe init dies? |
| 22:52.38 | Alex[sp3dev] | it's why there is pivot_root in the first place |
| 22:52.38 | jonpry | it does once busybox fails |
| 22:52.56 | jonpry | that has nothing to do with it |
| 22:53.24 | jonpry | the ramdisk works on all other kernels |
| 22:54.36 | jonpry | i need to see what happened with this init.android. maybe it suffered another code rearrangement |
| 22:54.44 | Alex[sp3dev] | i'd start with tracing where it dies. i mean, what syscall/kernel call returns error |
| 22:54.58 | jonpry | nothing returns an error |
| 22:55.07 | Alex[sp3dev] | so which kernel version if anything? we can probably reproduce it in qemu |
| 22:55.32 | jonpry | the programs memory gets all rearranged. so function calls go to the wrong places |
| 22:56.07 | jonpry | i dumped the processes memory after the crash and you can see that it no longer matches the binary |
| 22:56.13 | Alex[sp3dev] | so we need to figure out why this happens. this likely has to do with code in arch/mm |
| 22:56.40 | jonpry | it could be virtual memory gets swapped somehow |
| 22:56.52 | jonpry | or the filesystem loads the data incorrectly |
| 22:57.04 | jonpry | or exec() copies the binary into memory incorrectly |
| 22:57.49 | Alex[sp3dev] | well, i think bisecting is too easy, but can you name the last version that worked and the first that failed of those you have tested? |
| 22:58.06 | detule | 3.3.6 works 3.4 mainline fails |
| 22:59.33 | jonpry | i gotta go for a bit |
| 23:16.12 | jonpry | alright |
| 23:16.55 | jonpry | i don't think the problem is in /fs or it would effect all arch's |
| 23:22.11 | Cotulla | who knows |
| 23:22.16 | Cotulla | unaligned accesses and etc |
| 23:22.21 | detule | what's this arch_ioremap_caller in arch/arm in 3.4 |
| 23:22.46 | detule | http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=b12e9ba59c83f7df846602b201b64e4ddf28ccee |
| 23:24.20 | jonpry | our 3.3 tree has those patches |
| 23:24.35 | jonpry | back when we had mmu problems i added |
| 23:25.08 | detule | not that patch |
| 23:25.18 | detule | oh wait |
| 23:25.20 | detule | our tree |
| 23:25.56 | detule | guess you caught that before korg did |
| 23:28.35 | jonpry | mostly i was just confused and thought the patch was already merged |
| 23:29.03 | detule | this is a big mess, they've also taken out arch_idle() |
| 23:29.30 | Cotulla | what is instead ? :O |
| 23:30.07 | jonpry | idle of the day |
| 23:30.13 | detule | arhttp://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=ae940913030386884f259eb4d95ac4d93b57144f |
| 23:30.14 | Cotulla | hm |
| 23:30.43 | Cotulla | WTF |
| 23:30.55 | Cotulla | WTF to rename arch_idle to cpu_idle? |
| 23:32.06 | detule | our arch_idle is a lot more than cpu_do_idle... |
| 23:35.06 | jonpry | is that something we need to work on? |
| 23:36.23 | detule | no likely unrelated |
| 23:36.48 | jonpry | they seem to have gotten rid of all the fixup's from board files |
| 23:36.55 | jonpry | maybe fixup doesn't work anymore? |
| 23:37.45 | jonpry | although the dmesg seems to say it did: Memory: 99MB 78MB = 177MB total |
| 23:38.24 | jonpry | is this the same on 3.3? [ 0.000000] vector : 0xffff0000 - 0xffff1000 ( 4 kB) |
| 23:38.24 | jonpry | [ 0.000000] fixmap : 0xfff00000 - 0xfffe0000 ( 896 kB) |

| 23:44.22 | jonpry | i'm going to report this on lkml |
| 23:44.32 | jonpry | 3.4 is brokeass |
| 23:45.04 | jonpry | refuses to run executables reliably on htc rhodium |
| 23:45.05 | detule | here's the virtual memory layout http://pastebin.com/Sr0K7FqQ |
| 23:45.18 | detule | lol you'll get a lot of blank stares |
| 23:47.07 | jonpry | <PROTECTED> |
| 23:50.13 | detule | how about that guy that reported chroot failure on 3.4-rc1 |
| 23:51.12 | detule | think related to this? don't think he was on an ARM device |
| 23:51.35 | jonpry | i keep wondering if maybe he was not crazy |
| 23:51.57 | jonpry | but it seems like if this was happening on other platforms somebody would have noticed |
| 23:52.10 | detule | he was also talking about warning: .dynamic section for "/lib/libpthread.so.0" is not at the expected address (wrong library or version mismatch?) |
| 23:52.50 | detule | i mean address snafu |
| 23:53.35 | detule | but that's probably just because his chroot failed |
| 23:53.50 | jonpry | there's nothing really helpful there. except that it was happening in rc1 |
| 23:58.42 | Cotulla | ping me when u count down up to pages allocator pls |
