| 18:29.41 | freemangordon | Sep 22 19:26:07 Nokia-N900 kernel: [ 572.136657] Alignment trap: not handling instruction ece4 at [<4026d84c>] |
| 18:29.59 | kerio | wat |
| 18:30.08 | freemangordon | pulseaudio |
| 18:30.24 | kerio | wtf did you do |
| 18:30.30 | kerio | to my n900 |
| 18:30.40 | freemangordon | compiled it and seems I am hitting that |
| 18:31.23 | kerio | well fix the kernel |
| 18:31.25 | freemangordon | fortunately there is a compiler switch to disabl eunaligned access, lets see if it will work |
| 18:31.31 | kerio | or tell gcc to only do aligned access |
| 18:31.35 | kerio | hehe |
| 18:31.45 | kerio | maybe that's the problem with xserver? |
| 18:32.01 | freemangordon | NFC |
| 18:36.19 | int_ua | freemangordon: but why is that "__LINUX_ARM_ARCH__ < 6" when the title says "ARMv6+" ? |
| 18:36.33 | int_ua | why is it _less_ ? |
| 18:37.29 | freemangordon | because on < 6 it is prohibited |
| 18:37.39 | kerio | because it'll trap if CONFIG_ALIGNMENT_TRAP is set, *AND* if arch is 5 or less |
| 18:37.44 | kerio | on 6+, it'll not trap |
| 18:37.50 | freemangordon | :nod: |
| 18:43.28 | freemangordon | CONFIG_ALIGNMENT_TRAP is set in our kernel :( |
| 18:43.49 | kerio | of course it is |
| 18:43.53 | kerio | it's probably a good thing |
| 18:43.57 | kerio | just add that patch |
| 18:44.04 | kerio | if our CPU can handle unaligned access |
| 18:44.31 | freemangordon | no, it is not a good thing, as our CPU can handle it at a cost of 1 additional cycle (AIUI) |
| 18:44.45 | kerio | yeah but you fix that by adding that patch |
| 18:44.49 | kerio | or something |
| 18:45.07 | freemangordon | yeah, I can try |
| 18:45.09 | int_ua | offtopic: is that possible to connect touchscreen on N900 to desktop through network? |
| 18:45.20 | kerio | paaaaaaaaaaaaaaaaalit |
| 18:45.23 | kerio | dammit, he's not here |
| 18:45.29 | int_ua | =D |
| 18:45.30 | kerio | int_ua: what does that mean? |
| 18:46.00 | int_ua | kerio: just an idea. To use touchscreen on N900 on my desktop |
| 18:46.42 | int_ua | I've seen something like USB over IP in Linux long time ago... |
| 18:47.12 | int_ua | maybe there is something like this to connect the touchscreen? |
| 18:47.30 | kerio | well, there's VNC... |
| 18:48.22 | freemangordon | hmm, I replaced that code with a memset and now I have segmentation fault, something else is wring :D |
| 18:48.26 | freemangordon | *wrong |
| 18:48.41 | kerio | you what |
| 18:49.17 | freemangordon | it was an init loop that was causing SIGILL, I replaced it with memset and got sigsegv |
| 18:49.32 | kerio | cool, that's easier to diagnose :D |
| 18:49.35 | kerio | fix the damn kernel |
| 18:49.48 | freemangordon | no, it is not the kernel |
| 18:49.58 | kerio | sure it is, it traps unaligned access |
| 18:50.04 | kerio | and now you botched the aligned replacement |
| 18:50.20 | freemangordon | nahh, sigsegv is a different animal |
| 18:51.12 | freemangordon | hehe, I am stupid :D |
| 18:51.29 | freemangordon | memset's second argument is not array size ;) |
| 18:53.43 | kerio | you could just recompile the original source with the aligned access option |
| 18:53.58 | freemangordon | already did that, don;t help |
| 18:54.06 | kerio | wait, really? D: |
| 18:54.08 | kerio | then what's wrong? |
| 18:54.12 | freemangordon | NFC |
| 18:54.31 | freemangordon | lets see how it will be wit *correctly* called memset |
| 18:54.44 | kerio | also, is there some binary on my n900 that could do unaligned access? |
| 18:55.05 | kerio | some binary that comes from cssu-θ |
| 18:55.26 | freemangordon | kerio: it is most probably gcc issuing incorrect instruction |
| 18:55.37 | kerio | which gcc? |
| 18:56.07 | freemangordon | both zeq's and mine (4.7.2 linaro 2012.09) |
| 18:56.38 | kerio | yeah but did you use it already? |
| 18:56.39 | kerio | this new one |
| 18:57.02 | freemangordon | it runs YAY |
| 18:57.23 | kerio | YAY |
| 18:57.30 | kerio | until it'll segfault again |
| 18:57.35 | kerio | for instance, when accessing that initialized data |
| 18:57.42 | freemangordon | oulseaudio enable every damn hacking options, like fast-math and unsafe-optimisation and whatnot |
| 18:57.49 | kerio | hehe |
| 18:58.16 | freemangordon | I really wonder how this wirks at all (stock one) |
| 18:58.20 | freemangordon | *works |
| 18:58.37 | freemangordon | but now it works, lets see if there is sound |
| 18:59.01 | freemangordon | yes, there is |
| 18:59.04 | freemangordon | :D |
| 18:59.10 | kerio | :D |
| 18:59.19 | kerio | otoh, you should look for a more general fix |
| 18:59.24 | freemangordon | I know |
| 18:59.44 | kerio | new kernel-cssu! ^____^ |
| 18:59.50 | kerio | it might be the excuse to install it |
| 19:00.25 | freemangordon | OK, works after reboot too. |
| 19:01.41 | m0shbear | kerio: alignment issues usually trigger SIGBUS |
| 19:02.07 | m0shbear | SEGV is more pagetable protection issues |
| 19:02.22 | freemangordon | m0shbear: i have a clear message from the kernel |
| 19:02.28 | kerio | m0shbear: no, the SIGSEGV is from his botched replacement |
| 19:02.33 | kerio | the original issue is SIGILL iirc |
| 19:02.54 | freemangordon | yep |

| 19:03.03 | freemangordon | and that sigills in gdb |

| 19:03.21 | freemangordon | ece4 is vstmia |

| 19:03.53 | m0shbear | i know not arm asm |
| 19:03.55 | freemangordon | and r4 is not word aligned |
| 19:04.48 | m0shbear | and zeroing the unaligner bits -> segv? |
| 19:04.54 | freemangordon | though it seems like a problem in the toolchan |
| 19:05.37 | kerio | m0shbear: no, not knowing how memset works -> segv |
| 19:05.42 | kerio | :D |
| 19:05.44 | freemangordon | m0shbear: i passed memset array size as second parameter nad -1 as third |
| 19:05.53 | freemangordon | kerio: hehe |
| 19:06.23 | freemangordon | the expected result - sigsegv |
| 19:06.42 | m0shbear | is it possible to trap right before to do regs + callstack dump? |
| 19:07.05 | kerio | m0shbear: it's an already-diagnosed problem though |
| 19:07.18 | freemangordon | m0shbear: of course i can, i have gdb installed, but why should i do that? |
| 19:07.24 | kerio | new gcc generates code with unaligned access, and the kernel is configured to trap that |
| 19:07.36 | kerio | but it works fine in recent ARM archs |
| 19:07.37 | m0shbear | gcc 4.7? |
| 19:07.41 | freemangordon | yep |
| 19:07.44 | freemangordon | 4.6 too |
| 19:07.55 | kerio | freemangordon: then how does the thumb stuff work? |
| 19:07.59 | freemangordon | kerio: though the patch is for kernel unaligned access |
| 19:08.07 | kerio | oh |
| 19:08.17 | freemangordon | kerio: that is why i said it is most probably a toolchain problem |
| 19:08.24 | luf | I'm curious if someone using BT + synchronizing contact and more between phones :) |
| 19:08.26 | m0shbear | why not retain 4.5 to keep gcc from UA code generation? |
| 19:08.37 | kerio | because 4.7 is better |
| 19:08.46 | freemangordon | m0shbear: there is an option to disable it |
| 19:08.59 | freemangordon | which didn't help |
| 19:09.59 | m0shbear | how bloated is gcc's arm backend? |
| 19:10.09 | freemangordon | again a sign of misbehaving toolchain |
| 19:10.27 | kerio | freemangordon: did you properly make clean and make? |
| 19:10.28 | freemangordon | m0shbear: well, it is gcc-linaro, should be the best one available |
| 19:10.39 | freemangordon | kerio: come on :P |
| 19:10.53 | kerio | no srsly |
| 19:10.57 | freemangordon | iirc |
| 19:11.02 | m0shbear | proably a few assert()s here and there will trigger ICEs, making it easier to hunt down the source of the unavoidable UAs |
| 19:11.17 | kerio | m0shbear: how do you test all codepaths though? |
| 19:12.32 | m0shbear | i want to say lint, but know im prolly wrong |
| 19:12.43 | freemangordon | m0shbear: pulseaudio source and toolchain are available to be downloaded, I will owe you a beer if you can trigger an ICE |
| 19:13.41 | freemangordon | m0shbear: http://wiki.maemo.org/CSSU-thumb_toolchain_setup_%28gcc4.7.2-linaro%29 |
| 19:13.53 | freemangordon | and puleaudio in in maemo repos |
| 19:14.00 | freemangordon | *pulseaudio |
| 19:14.25 | freemangordon | if you want to play with it I will hand you a couple of patches you'll need |
| 19:14.26 | kerio | ICE? |
| 19:14.33 | freemangordon | internal compiler error |
| 19:16.02 | m0shbear | the first trick is to figure out the offensive lines of code |
| 19:16.37 | freemangordon | for (c = 0; c < PA_CHANNELS_MAX; c++) |
| 19:16.37 | freemangordon | m->map[c] = PA_CHANNEL_POSITION_INVALID; |
| 19:17.04 | freemangordon | pulseaudio-0.9.15\src\pulse\channelmap.c:165 |
| 19:17.04 | kerio | why does m->map point to an unaligned thing? |
| 19:17.24 | freemangordon | because m is a structure |
| 19:17.38 | kerio | i said m->map, not m |
| 19:17.48 | kerio | and i said point to |
| 19:18.04 | kerio | unless the problem is m->map itself |
| 19:18.09 | m0shbear | and inducing padding may unalign other instances |
| 19:18.19 | freemangordon | typedef struct pa_channel_map { |
| 19:18.22 | freemangordon | uint8_t channels; |
| 19:18.24 | freemangordon | /**< Number of channels */ |
| 19:18.27 | freemangordon | pa_channel_position_t map[PA_CHANNELS_MAX]; |
| 19:18.30 | freemangordon | /**< Channel labels */ |
| 19:18.32 | freemangordon | } pa_channel_map; |
| 19:18.38 | freemangordon | that is why |
| 19:19.06 | kerio | ...that's stupid |
| 19:19.10 | kerio | WHY UINT8 |
| 19:19.30 | m0shbear | uint8_t _pad[3]; after .channels |
| 19:19.37 | m0shbear | why or why not |
| 19:20.02 | kerio | *why* |
| 19:20.28 | freemangordon | m0shbear: no way, there are closed source PA plugins from Nokia |
| 19:20.33 | m0shbear | probably the code was assumed for byte addressable machines |
| 19:20.43 | m0shbear | namely x86 |
| 19:20.57 | freemangordon | ARM can access bytes, not sure for NEON SIMD |
| 19:21.48 | 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 |
| 19:22.44 | m0shbear | apart from x86, which other arches are alignment-agnostic wrt word access? |
| 19:26.09 | m0shbear | also, is it possible to do struct translation much like ksplice? |
| 19:26.15 | luf | Shit. obexd redefine one type which prevent phone synchronizing :( |
| 19:26.33 | m0shbear | in order to not break abi yet work around gcc bug |
| 19:28.12 | freemangordon | m0shbear: i'll just patch it to use memset and will move on |
| 19:28.43 | luf | but it seems nobody is using it as I see no bug report for it. |
| 19:30.26 | m0shbear | i'll get to playing with unaligned struct members after my pm nap and dinner |
| 19:30.48 | m0shbear | i expect fun times and a few ICEs |
