| 11:23.21 | EvilR1ck | hey guys. I built my kernel using the uclibc MIPS cross compile tools that are built by buildroot . My 2.4.29 kernel works fine but If I make a 2.4.30 kernel and modules all my modules dont load. they dump with an "unaligned data access" error and a ton of register info and what not. |
| 11:23.23 | EvilR1ck | any ideas? |
| 11:33.23 | rfs | EvilR1ck: just a wild guess, does mips have alignment fixup handler like ARM? |
| 11:33.37 | rfs | and if so, maybe in the 2.4.30 config its not enabled by default? |
| 11:33.39 | EvilR1ck | could be .. how do I tell? |
| 11:33.48 | rfs | diff the .config files for the kernel... |
| 11:33.48 | EvilR1ck | that sounds about right |
| 11:34.01 | rfs | or arch/mips/defconfig or whatever it is you use... |
| 11:34.04 | EvilR1ck | k sec.. |
| 11:34.21 | EvilR1ck | have to conenct to my home machien to check |
| 11:37.35 | EvilR1ck | ok.. there are a few diffrences |
| 11:38.03 | EvilR1ck | what am I looking for? |
| 11:39.30 | rfs | honestly i don't know :( |
| 11:39.32 | EvilR1ck | CONFIG_CPU_HAS_LLSC=y ? |
| 11:40.03 | EvilR1ck | wait no. I know what that is :) |
| 11:40.05 | rfs | let's look that one up in kconfig help.. |
| 11:41.08 | EvilR1ck | its a mips flag.. it allows you to force ll and sc support |
| 11:41.16 | EvilR1ck | I forced it on on my 2.4.29 build |
| 11:41.33 | EvilR1ck | and I thought removing it from the 2.4.30 build may help |
| 11:41.36 | EvilR1ck | it didnt :/ |
| 11:41.54 | EvilR1ck | the rest is netfilter stuff |
| 11:42.11 | rfs | hmm |
| 11:42.41 | rfs | you'll need to ask someone who actually has mips :) or maybe google for mips alignment fixup or somesuch. |
| 11:43.29 | EvilR1ck | checking a makefile diff |
| 11:43.50 | EvilR1ck | "-fno-strict-aliasing -fno-common -g" the -g option is new in 2.4.30 |
| 11:43.58 | EvilR1ck | any idea what it does? |
| 11:44.26 | rfs | that just turns on debugging symbols. |
| 11:44.47 | rfs | they'll later be removed by 'strip' command. |

| 14:12.45 | EvilR1ck | I built the madwifi modules with the gnu toochain which explains why they work :) |
| 14:16.15 | mjn3-work | yes. the linux mips maintainers aren't interested in taking patches to fix 2.4.x when built with gcc 3.4 |

| 21:29.20 | ashes | hi |
| 21:29.38 | solar | lo |
| 21:29.55 | Rigidus | guys, i'd have a question :) |
| 21:29.59 | solar | ashes: did you see ssp is going mainline? |
| 21:30.21 | solar | July 01 2005 (gcc-patches ml) |
| 21:30.33 | Rigidus | i have a netgear di-602 router powered by sparc32 cpu |
| 21:30.52 | ashes | i didn't see |
| 21:31.27 | Rigidus | it has a 2MB flash and 16MB RAM |
| 21:31.43 | ashes | libssp |
| 21:31.48 | ashes | hmm |
| 21:31.58 | Rigidus | i would need a small linux distribution for it, but the problem is |
| 21:32.48 | Rigidus | i haven't found any sparc32 based embedded distro for it |
| 21:33.03 | Rigidus | any idea? :) |
| 21:33.05 | Rigidus | thx |
| 21:39.01 | solar | ashes: yeah not super fond of that |
| 21:39.39 | ashes | it looks like it checks if ssp is in libc first |
| 21:40.43 | ashes | so its good all around. it will work standalone with gcc, or with uclibc, openbsd, and patched glibc |
| 21:40.50 | solar | yeah but the general idea of puttting those functions into it's own lib seems wasteful. 4K + 5.5K header (PAGE_SIZE + ELF_HEADERS) * 65536 |
| 21:41.06 | solar | yeah it's a good thing |
| 21:41.08 | ashes | you dont have to |
| 21:41.16 | solar | looks like they have been finding and fixing bugs also. |
| 21:41.18 | ashes | either way it optional |
| 21:41.22 | solar | nod |
| 21:42.02 | solar | but there are some advantages also. per thread guards |
| 21:43.28 | solar | should be interesting. I'm kinda shocked that redhat has seen the light. |
| 21:43.45 | solar | I welcome it as of now, thats for sure |
| 21:43.45 | ashes | i bought granite today for my computer desk. should be finished next week |
| 21:44.08 | solar | granite as in rock? |
| 21:44.13 | ashes | yes |
| 21:44.21 | ashes | polished |
| 21:44.33 | solar | for bling effect? |
| 21:44.55 | ashes | ive worn the top off my desk, and i like the shape, so im putting a new top on it which should last a long time |
| 21:45.07 | solar | oh. |
| 21:45.25 | solar | Rigidus: better use buildroot. |
| 21:45.33 | ashes | i have a corner desk |
| 21:45.50 | solar | sparc has been kinda overlooked. embedded sparc hardware is rare++ |
| 21:53.52 | Rigidus | solar: thx |
| 21:55.00 | andersee | Rigidus: indeed. you can get old sun sparc boxes off ebay and such, but few folks find reto computing of that sort to be as exciting as they had hoped |
| 21:55.42 | andersee | Rigidus: sparc seems to following in the footsteps of the DEC alpha chip... |
| 21:56.04 | andersee | Rigidus: just not quite so far along the pathway |
| 21:56.13 | andersee | Rigidus: somewhat sad really |
| 21:58.09 | andersee | Rigidus: the LEON sparc is sortof interesting, being an open source core... |
| 21:58.50 | andersee | Rigidus: but generally, sparc tends to be the path less traveled these days, and that makes all the difference. |
| 21:59.55 | solar | seems that x86/mips/arm are the best supported around here, and by chipmakers |
| 22:01.12 | solar | with ppc catching up as of recent |
| 22:01.38 | andersee | best supported by chipmakers tends to produce best supported by uclibc |
| 22:04.43 | solar | it's my understanding that sparc chipsets tend to produce more heat and require more power/volts than pretty much another other of the major cpus players out on the market |
| 22:05.39 | solar | I've never tested that, but I'll take that one at face value as it seems pretty logical for that vendor |
| 22:08.25 | SpanKY | i updated the sparc port so static mostly works ... |
| 22:08.47 | SpanKY | i also updated the TODO to cover the few neglected arches that i can hack on |

| 22:44.58 | SpanKY | sorry, got interrupted heh |
| 22:45.04 | SpanKY | i didnt finish my statement :) |
| 22:45.32 | SpanKY | soooooo i found the elf spec and i was reading it through ... |
| 22:45.41 | SpanKY | it describes the hash tables a bit ... but it just says |
| 22:45.57 | SpanKY | A hash table of Elf32_Word objects supports symbol table access. |

| 22:46.11 | SpanKY | and gives a little diagram (page 84 in my version) |
| 22:46.45 | SpanKY | so i guess that means that each is a 32bit element ? wording seems a little vague ... |
| 22:48.12 | SpanKY | the thing that throws me is that their hash function uses unsigned long types ... |
| 22:48.52 | SpanKY | but their algorithm limits the hash values to 7 bytes right ? (the & 0xf0000000 test triggers a right shift of 24 bytes) |
| 22:50.47 | andersee | SpanKY: are you concerned there might be a single application with more than 2684354560 symbols? |
| 22:51.40 | SpanKY | not really, i'm just double checking all the types since ive found a few places where they get truncated :) |
| 22:52.30 | SpanKY | for example the hash code was declaring the bucket stuff as 'unsigned long' in struct elf_resolve and was using pointers to refer to it |
| 22:52.39 | SpanKY | so it ended up eating 2 hash codes at a time on my machine |
| 22:52.46 | andersee | hmmm |
| 22:53.19 | SpanKY | ive forced them to uint32_t and that seemed to fix hash table reading on x86_64 |
| 22:53.29 | SpanKY | (at least the output of LD_DEBUG matched that of `readelf`) |
| 22:54.42 | SpanKY | i'm just double checking behavior versus docs now to make sure forcing it to uint32_t isnt a mistake |
| 22:55.13 | andersee | the spec does tend to be a bit vague |
| 22:55.34 | andersee | might be worth the trouble of finding the x86_64 version of the ELF spec |
| 22:55.40 | andersee | just to double check |
| 22:55.55 | SpanKY | where can i find that guy ? |
| 22:56.10 | andersee | not sure |
| 22:56.12 | SpanKY | oh oh oh, gimme :) |
| 22:56.19 | andersee | I'd start by asking google |
| 22:56.36 | SpanKY | i'm going to, but asking you tends to be a bit faster since you know more than me :) |
