| SpacedOut | DocScrutinizer05: I missed getting in on the USB charging discussion. I've tracked down a problem where plugging into a wall charger works, but plugging into a computer usb port doesn't charge and the computer doesn't see the N900. musb_core.c struct musb_ctx holds hardware register values, it can get it into that state. | 00:25 |
|---|---|---|
| SpacedOut | `echo mem > /sys/power/state` is the most reliable way to get it into that state. If anyone is wanting to debug it I have a patch for compiling the USB drivers as modules which also fixes some concurrency problems in the charger detection routines, a whole bunch of debugging print messages. | 00:29 |

| DocScrutinizer51 | SpacedOut: we concluded during 18months of h-e-n development that musb-hdrc has to be monolithic. | 01:09 |
| SpacedOut | I'm fine with it being compiled in the kernel with the default configuration, but I have it working as module, and that is very handy if anyone is trying to do development or debugging on it. | 01:11 |
| SpacedOut | Which I was. | 01:12 |
| DocScrutinizer51 | and setting device to suspend-to-ram is kinda useless since it either wakes up again after 10s due to signal-level change message from cmt, or you block that and it won't even wake up on inbound call | 01:12 |
| SpacedOut | I was wanting to point out that some of the problems you were having with it detecting the usb port and charging sounded familiar with what I was debugging, depending on the specifics and it all gets pretty fuzzy trying to track down all the variables. | 01:13 |
| DocScrutinizer51 | or you have very secrit wisdom how to tell bb5 cmt to stop spamming unsol msgs | 01:13 |
| SpacedOut | I think suspend to ram is useless unless you are in offline mode, and that is exactly how I use it, not very often, but I want it near off, but not have to boot it up when I'm ready to use it again. | 01:14 |
| DocScrutinizer51 | yep, this works. speedevil done this | 01:15 |
| DocScrutinizer51 | sorry for terse answers | 01:15 |
| DocScrutinizer51 | N900 | 01:15 |
| SpacedOut | I didn't get the reference or what part works, the current suspend to ram works for me after my patches for one to let it work with a computer USB port after resuming. | 01:18 |

| freemangordon | fortunately there is a compiler switch to disabl eunaligned access, lets see if it will work | 21:31 |
| kerio | or tell gcc to only do aligned access | 21:31 |

| int_ua | why is it _less_ ? | 21:36 |
| freemangordon | because on < 6 it is prohibited | 21:37 |
| kerio | because it'll trap if CONFIG_ALIGNMENT_TRAP is set, *AND* if arch is 5 or less | 21:37 |
| kerio | on 6+, it'll not trap | 21:37 |
| freemangordon | :nod: | 21:37 |
| freemangordon | CONFIG_ALIGNMENT_TRAP is set in our kernel :( | 21:43 |
| kerio | of course it is | 21:43 |
| kerio | it's probably a good thing | 21:43 |
| kerio | just add that patch | 21:43 |
| kerio | if our CPU can handle unaligned access | 21:44 |
| freemangordon | no, it is not a good thing, as our CPU can handle it at a cost of 1 additional cycle (AIUI) | 21:44 |
| kerio | yeah but you fix that by adding that patch | 21:44 |

| freemangordon | yeah, I can try | 21:45 |

| int_ua | kerio: just an idea. To use touchscreen on N900 on my desktop | 21:46 |
| int_ua | I've seen something like USB over IP in Linux long time ago... | 21:46 |
| int_ua | maybe there is something like this to connect the touchscreen? | 21:47 |
| kerio | well, there's VNC... | 21:47 |
| freemangordon | hmm, I replaced that code with a memset and now I have segmentation fault, something else is wring :D | 21:48 |
| freemangordon | *wrong | 21:48 |
| kerio | you what | 21:48 |
| freemangordon | it was an init loop that was causing SIGILL, I replaced it with memset and got sigsegv | 21:49 |
| kerio | cool, that's easier to diagnose :D | 21:49 |
| kerio | fix the damn kernel | 21:49 |
| freemangordon | no, it is not the kernel | 21:49 |
| kerio | sure it is, it traps unaligned access | 21:49 |
| kerio | and now you botched the aligned replacement | 21:50 |
| freemangordon | nahh, sigsegv is a different animal | 21:50 |
| freemangordon | hehe, I am stupid :D | 21:51 |
| freemangordon | memset's second argument is not array size ;) | 21:51 |
| kerio | you could just recompile the original source with the aligned access option | 21:53 |
| freemangordon | already did that, don;t help | 21:53 |
| kerio | wait, really? D: | 21:54 |
| kerio | then what's wrong? | 21:54 |
| freemangordon | NFC | 21:54 |
| freemangordon | lets see how it will be wit *correctly* called memset | 21:54 |
| kerio | also, is there some binary on my n900 that could do unaligned access? | 21:54 |
| kerio | some binary that comes from cssu-θ | 21:55 |
| freemangordon | kerio: it is most probably gcc issuing incorrect instruction | 21:55 |
| kerio | which gcc? | 21:55 |
| freemangordon | both zeq's and mine (4.7.2 linaro 2012.09) | 21:56 |
| kerio | yeah but did you use it already? | 21:56 |
| kerio | this new one | 21:56 |
| freemangordon | it runs YAY | 21:57 |
| kerio | YAY | 21:57 |
| kerio | until it'll segfault again | 21:57 |
| kerio | for instance, when accessing that initialized data | 21:57 |

| freemangordon | m0shbear: i have a clear message from the kernel | 22:02 |
| kerio | m0shbear: no, the SIGSEGV is from his botched replacement | 22:02 |

| kerio | :D | 22:05 |
| freemangordon | m0shbear: i passed memset array size as second parameter nad -1 as third | 22:05 |
| freemangordon | kerio: hehe | 22:05 |
| freemangordon | the expected result - sigsegv | 22:06 |
| m0shbear | is it possible to trap right before to do regs + callstack dump? | 22:06 |
| kerio | m0shbear: it's an already-diagnosed problem though | 22:07 |
| freemangordon | m0shbear: of course i can, i have gdb installed, but why should i do that? | 22:07 |
| kerio | new gcc generates code with unaligned access, and the kernel is configured to trap that | 22:07 |
| kerio | but it works fine in recent ARM archs | 22:07 |
| m0shbear | gcc 4.7? | 22:07 |
| freemangordon | yep | 22:07 |
| freemangordon | 4.6 too | 22:07 |
| kerio | freemangordon: then how does the thumb stuff work? | 22:07 |
| freemangordon | kerio: though the patch is for kernel unaligned access | 22:07 |
| kerio | oh | 22:08 |
| freemangordon | kerio: that is why i said it is most probably a toolchain problem | 22:08 |
| luf | I'm curious if someone using BT + synchronizing contact and more between phones :) | 22:08 |
| m0shbear | why not retain 4.5 to keep gcc from UA code generation? | 22:08 |
| kerio | because 4.7 is better | 22:08 |
| freemangordon | m0shbear: there is an option to disable it | 22:08 |
| freemangordon | which didn't help | 22:09 |
| m0shbear | how bloated is gcc's arm backend? | 22:10 |
| freemangordon | again a sign of misbehaving toolchain | 22:10 |
| kerio | freemangordon: did you properly make clean and make? | 22:10 |
| freemangordon | m0shbear: well, it is gcc-linaro, should be the best one available | 22:10 |
| freemangordon | kerio: come on :P | 22:10 |
| kerio | no srsly | 22:10 |
| freemangordon | iirc | 22:10 |
| m0shbear | proably a few assert()s here and there will trigger ICEs, making it easier to hunt down the source of the unavoidable UAs | 22:11 |
| kerio | m0shbear: how do you test all codepaths though? | 22:11 |
| m0shbear | i want to say lint, but know im prolly wrong | 22:12 |
| freemangordon | m0shbear: pulseaudio source and toolchain are available to be downloaded, I will owe you a beer if you can trigger an ICE | 22:12 |
| freemangordon | m0shbear: http://wiki.maemo.org/CSSU-thumb_toolchain_setup_%28gcc4.7.2-linaro%29 | 22:13 |
| freemangordon | and puleaudio in in maemo repos | 22:13 |
| freemangordon | *pulseaudio | 22:14 |
| freemangordon | if you want to play with it I will hand you a couple of patches you'll need | 22:14 |
| kerio | ICE? | 22:14 |
| freemangordon | internal compiler error | 22:14 |
| *** int_ua has quit IRC | 22:15 | |
| m0shbear | the first trick is to figure out the offensive lines of code | 22:16 |
| freemangordon | for (c = 0; c < PA_CHANNELS_MAX; c++) | 22:16 |
| freemangordon | m->map[c] = PA_CHANNEL_POSITION_INVALID; | 22:16 |
| freemangordon | pulseaudio-0.9.15\src\pulse\channelmap.c:165 | 22:17 |
| kerio | why does m->map point to an unaligned thing? | 22:17 |
| freemangordon | because m is a structure | 22:17 |
| kerio | i said m->map, not m | 22:17 |
| kerio | and i said point to | 22:17 |
| kerio | unless the problem is m->map itself | 22:18 |
| m0shbear | and inducing padding may unalign other instances | 22:18 |
| freemangordon | typedef struct pa_channel_map { | 22:18 |
| freemangordon | uint8_t channels; | 22:18 |
| freemangordon | /**< Number of channels */ | 22:18 |
| freemangordon | pa_channel_position_t map[PA_CHANNELS_MAX]; | 22:18 |
| freemangordon | /**< Channel labels */ | 22:18 |
| freemangordon | } pa_channel_map; | 22:18 |
| freemangordon | that is why | 22:18 |
| kerio | ...that's stupid | 22:19 |
| kerio | WHY UINT8 | 22:19 |
| m0shbear | uint8_t _pad[3]; after .channels | 22:19 |
| m0shbear | why or why not | 22:19 |
| kerio | *why* | 22:20 |
| freemangordon | m0shbear: no way, there are closed source PA plugins from Nokia | 22:20 |
| m0shbear | probably the code was assumed for byte addressable machines | 22:20 |
| m0shbear | namely x86 | 22:20 |
| freemangordon | ARM can access bytes, not sure for NEON SIMD | 22:20 |
| freemangordon | though it is a toolchain problem, if i find time will try to reproduce it with a simple helloworld.c and open a bug | 22:21 |
| m0shbear | apart from x86, which other arches are alignment-agnostic wrt word access? | 22:22 |
| m0shbear | also, is it possible to do struct translation much like ksplice? | 22:26 |
| luf | Shit. obexd redefine one type which prevent phone synchronizing :( | 22:26 |
| m0shbear | in order to not break abi yet work around gcc bug | 22:26 |
| freemangordon | m0shbear: i'll just patch it to use memset and will move on | 22:28 |
| luf | but it seems nobody is using it as I see no bug report for it. | 22:28 |
| *** dhbiker has quit IRC | 22:29 | |
| m0shbear | i'll get to playing with unaligned struct members after my pm nap and dinner | 22:30 |
| m0shbear | i expect fun times and a few ICEs | 22:30 |
| *** toxaris has joined #maemo-ssu | 22:33 | |
| freemangordon | luf: you still play with obexd? I am eager for new bluetoothd to test, i use BT pretty much | 22:37 |
| luf | freemangordon: unfortunately yes. | 22:44 |
| luf | I stucked with some stupid mistake with pointers but I can't locate it L( | 22:45 |
| luf | BTW bluez-4.99 has more problems - It has some delay during connecting with HF and also it doesn't show the battery level :( | 22:46 |

| luf | for what are you using BT? | 23:19 |
| freemangordon | HF, file transfer,what else... lemme think | 23:20 |
| freemangordon | aah, mouse, keyboard | 23:20 |
| *** Guest57704 has joined #maemo-ssu | 23:20 | |
| luf | HF in car (also phonebook, MAP, ...) or just sound? | 23:21 |
| freemangordon | luf: sending contacts sometimes | 23:21 |
| freemangordon | hf in my ear | 23:21 |
| freemangordon | well, maybe it is HS profile didn't check it | 23:21 |
| luf | np. thanks for the info. | 23:22 |
