01:32.35SGMhi guys
01:32.41SGMa quick question
01:32.54SGMI was forwarded here from #uclibc
01:33.16SGMI compiled an environment using buildroot
01:33.29SGMbut I can't load modules
01:33.34SGMwhen I do a depmod -a
01:33.48SGMit tells me there are unresolved symbols
01:35.02SGMdoes enybody know what's the problem?
01:35.23T0mWno
01:35.40jacquesthat's a kernel issue
01:36.13SGMhmm... what may cause it?
01:36.49T0mWdid you check the kernel symbols file?  are they truely missing?
01:37.19jacquesit's like asking what could case a segfault
01:37.51T0mWSGM: you on a linux box right now?
01:38.22SGMT0mW: yes, I have it running on a vmware
01:38.49*** join/#elinux file[laptop] (n=jcolp@mctnnbsa24w-142167049176.nb.aliant.net)
01:39.13T0mWok, then where the boot kernel is located (vmlinuz) you'll find a file called "system.map" or "system.map-blah-blah-version"
01:39.31SGMyeah, I have a system.map
01:39.40T0mWSGM, look at the file.  it is the known public symbols of the kernel
01:39.49SGMyes, I know that
01:39.55SGMthe symbols are there
01:40.39T0mWthat's as far as I can take you then.
01:41.14SGMhmm... I'm booting from a virtual cd
01:41.28SGMand my system.map file is in /boot + a link in /
01:41.32SGMon the root fs
01:41.45T0mWI generally don't do modules with embedded linux.  I incorporate the code into the kernel
01:42.09T0mWSGM: you write this module yourself?
01:42.16SGMno
01:42.17SGM:)
01:42.34SGMI'm trying to load the fusion module from directfb
01:42.56T0mWwhat is that, a binary only module, no source?
01:43.36jacquesdirectfb is open source
01:43.49SGMsource
01:43.54T0mWif you have the module source, compile it in as a non-module.  
01:44.54T0mWhowever, you must be sure that the module source is for the version of kernel you want to use it for.  Linux is a moving target, things change rapidly in the 2.6 kernel.
01:45.21SGMwell it compiles with the 2.4 headers
01:45.26T0mWif the source is not in the kernel distribution (from ftp.kernel.org), then you can run into various issues
01:45.38SGMI also had the same problem trying to load the vmnet virtual net module
01:46.02T0mWwhat is the version of the running kernel on the system?
01:46.02SGMand I'm using a vanilla kernel
01:46.06SGM2.4.31
01:46.38T0mWyou may have to try dropping back to something like 2.4.21 or 2.4.16 etc.
01:47.08SGMI don't think the problem is with the kernel version itself...
01:47.33T0mWAYMK, there are no pat answers to a compile / link problem, you really have to "be there"
01:48.13*** join/#elinux GPSFan_ (n=Ken@65.121.49.208)
01:48.28T0mWso, if it is not a problem with the kernel version, why not include the code into the kernel: non module?
01:49.40T0mWhang it into the kernel tree, add a config option, then re-compile the kernel
01:50.57SGMthis is the next thing I'm gonna try
01:51.25SGMbut first I really want to know why it doesn't want to load... :/
01:52.32T0mWthe mind reels with possiblities
01:53.14T0mWwhy isn't the fusion driver part of the kernel anyway?  Poison license?
01:54.04T0mWwhat a minute, why are you using buildroot to build this module?!
01:55.17T0mWyou don't build kernels / modules for systems with buildroot.  buildroot is designed specifically to function as a cross-platform development environment: e.g. building an ARM kernel on a PC.
02:00.05SGMI wanted to make a small environment
02:00.10SGMthat's why I used buildroot
02:01.12T0mW"small environment" ?
02:02.06T0mWI'm about ready to start work for the night.....................
02:04.11SGMyeah, something like small linux installation where I can test software
02:05.03T0mWlike I said, buildroot is a cross platform development environ.
02:05.59Russtoo bad qemu isn't up to par yet
02:06.11Russdoesn't vmware have a user-net thing like qemu?
02:07.00jacquesRuss, qemu isn't u pto par in what way?
02:07.09Russspeed
02:07.40jacquesah yeah, compared to vmware
02:08.12RussI don't know whether or not to be pissed off at qemu, or winxp
02:08.22RussI did a winxp install and patch install in qemu
02:08.35Russonto a real drive (ie, hda=/dev/hdc
02:09.04Russthen, when I boot the drive, windows just resets the computer when it tries to load
02:09.45jacques:-\
02:10.11Russlast thing I see if I boot to safe mode is mup.sys
02:10.24Russwhich is aparently the last thing windows loads before it "initializes hardware"
02:10.40Russeverymessage board out there has about 80 different "solutions" to fix the problem
02:11.07jacquesargh
02:14.28Russbtw, I heard someone mentioning 2.4.x
02:18.39Russdon't forget that there was a fix in the 2.6.11 timeframe for ARM dealing with page table mappings
02:18.48Russprobably fixed in 2.4.something...
02:30.28Russ"[ARM] Fix slab corruption issues triggered with pud_t integration."
02:30.48Russ(check that PMD_SHIFT == 21,not 20

15:49.33prpplague:(
15:49.37prpplagueLinuxCart: its not
15:49.50prpplaguei've tried everything i can think of to make it more stable
15:50.04prpplaguenothing seems to work
15:53.53LinuxCartoh!
15:54.13LinuxCartif it is a HW problem, solution is mainly HW
15:54.28LinuxCartand doing HW withouth redoing is quite difficult
15:54.37MonMothaprpplague: still doing the same thing as before?
15:54.40LinuxCarthave you tried better grounding
15:54.45LinuxCart¿?
15:55.02MonMothahave you implemented all the SA-1110 UDC workarounds (presumably, if it's running linux)
15:55.45prpplagueMonMotha: all the ones i could find
15:55.51prpplagueMonMotha: do you have a list of them?
15:56.02MonMothaprpplague: Intel does, somewher
15:56.12MonMothaI have a hardcopy of the spec update at home
15:56.24prpplagueMonMotha: i think thats what i have but i will double check
15:56.26MonMothait's in one of the numerous SA-1110 specification updates
15:56.51MonMothadetails the "spin on the register, writing and reading it, until it takes the value you just poked it with" workaround, amongst others
15:56.51prpplagueMonMotha: yea well, i'm totally frustrated
15:57.06MonMothawell, the SA-1110 UDC is rather broken
15:57.10prpplagueMonMotha: yea, well i'm using stock linux code for this
15:57.26MonMothaI think Linux implements all the recommended workarounds, but I'm not sure of that
15:57.56prpplagueMonMotha: yea there are a number of comments to that effect
15:58.39MonMothacheck with Joshua Wise in #handhelds.org
15:58.45MonMothahe hacked the crap out of the SA-1110 UDC a while back
15:59.44CosmicPenguinprpplague: you're doing UDC?
16:00.00prpplagueCosmicPenguin: yea
16:00.07CosmicPenguinWow - good luck with all of that
16:00.29prpplagueCosmicPenguin: yea the details are even worse
16:00.36prpplagueCosmicPenguin: giant deal depending on it
16:00.36MonMothaprpplague: try forcing the host to give the SA-1110 device data in smaller hunks, if possible
16:00.49prpplagueCosmicPenguin: and i can't change any of the legacy hardware
16:01.01prpplagueMonMotha: yea, i've been tinkering with the values
16:01.09prpplagueMonMotha: i set the mtu's pretty low
16:01.15prpplagueMonMotha: still have a problem
16:01.33prpplagueMonMotha: changed the rsize and wsize down, but still getting the problem
16:01.44prpplagueMonMotha: even tried going through a usb hub
16:02.15MonMothahum, I always had problems if I placed a hub between my PC and my ipaq
16:02.20MonMotharandom disconnects, just like you're getting
16:02.33CosmicPenguinprpplague: well, when that all crashes and burns, have your client turn to the AU1200 where we are very happily doing both UDC and OTG.... :p
16:03.12MonMothaprpplague: most of my experience with this stuff is with my ipaq
16:04.37prpplagueCosmicPenguin: going with the s3c2410 which works fine
16:04.49prpplagueMonMotha: yea, i figured as much
16:04.59prpplagueMonMotha: but it should be pretty similiar
16:09.50MonMothayes
16:16.34prpplagueits gonna take me a week to check for all these errata items
16:16.53prpplagueMonMotha: which kernel were you using with your ipaq stuff?
16:20.39MonMothaI think it was a 2.4.18-rmk<something>-hh<something>
16:20.45MonMothaone of the later rmks
16:21.04MonMothaand yes, there is a TON of errata on the SA-1110 UDC
16:21.46MonMothawell, my bank just pissed me the hell off
16:21.52MonMothathey decided to sign me up for a bunch of spam
16:22.01MonMothathere is at least a (presumably working) opt-out link, but they shouldn't do that
16:22.22MonMothathey ahve my email for online banking only, and in fact in their original privacy policy said they'd never share it outside their company
16:22.32MonMothaI'm half tempted to walk in and close out my account just to send them a message
16:22.38MonMothathere's plenty of other banks in the area
