Should modules for different kernels differ?

I'm trying to build acpi_call-git from the AUR. The build seems to go rather too smoothly. I uninstalled a custom kernel (which I only have for debugging) which leaves the standard Arch and Arch LTS kernels installed. I have the headers installed for both kernels:
$ pacman -Qs linux-[lts-]*headers
local/linux-headers 3.11.4-1
Header files and scripts for building modules for Linux kernel
local/linux-lts-headers 3.10.15-1
Header files and scripts for building modules for Linux-lts kernel
What is confusing me is that the package seems to build identical modules for the two kernels and I am not sure whether that's right:
$ diff pkg/acpi_call-git/usr/lib/modules/extramodules-3.11-ARCH/acpi_call.ko.gz pkg/acpi_call-git/usr/lib/modules/extramodules-3.10-lts/acpi_call.ko.gz
$ echo $?
0
Shouldn't there be a difference between the two? That is, I know that you typically need modules which match the kernel - otherwise the modules can't be loaded. So presumably if building module M for kernel K1 produces M1, and building module M for kernel K2 produces M2, then M1 cannot be identical with M2.
Is there a problem here or am I just horribly confused?

If the kernel functions (especially the specifications) used by acpi_call haven't changed, then the module could indeed be the same for both kernels.
You'd have to check the kernel commits for acpi related changes to be sure.

Nvidia module for custom kernel

Hi all. I've compiled a custom kernel using abs according to the instructions on the wiki, but I'm having a hard time installing the nvidia module using the instructions on the Nvidia page of the wiki. The install always aborts complaining of not being able to find the kernel source. I do have the kernel-headers installed:
[root@myhost greg]# pacman -Ss linux-headers
core/linux-headers 3.1.5-1 [installed]
Header files and scripts for building modules for linux kernel
I've also edited the nvidia.install and PKGBUILD files to point to the correct version file:
[greg@myhost ~]$ cat /lib/modules/3.1.5-1-test/extramodules/version
3.1.5-1-test
I've really searched hard, but can find no remedy. Any ideas?
Thanks in advance.

From what I can see, the only installable package that was built is linux-test-3.1.5-1-x86_64.pkg.tar.xz. That's with the PKGBUILD file supplied from /var/abs/core/linux as per the wiki.

Script to easily build modules for custom kernels

I got bored, and thought of this ages ago. I have no use for it now, but i'm sure someone else will.
run:
abs-module $modulename $kernel
$modulename is any kernel module that's available in /var/abs, so if you have some that arent in a default abs, put em in /var/abs/local and they will be spotted by this.
$kernel is the name of the kernel that you want to compile for. this can be found with 'uname -r'. If $kernel is not specified, then it will default to what you are running now.
this will only work for module packages that have a variable called _kernver which sets the kernel it will be compiled for. I know all the winmodems, ATi and drivers I maintain do, not sure about some of the others. nvidia won't work.
#! /bin/bash
# Set the variables up
module="$1"
kernel="$2"
pacman="1"
current="`uname -r`"
# Check things
if [ -z "$module" ]; then
echo "No module specified"
return 1
fi
if [ -z "$kernel" ]; then
echo "No kernel specified, building for: $current"
kernel="$current"
fi
if [ ! -e "/lib/modules/$kernel/build" ]; then
echo "Specified kernel is not installed"
return 1
fi
# Check if module exists
origdir="`find /var/abs -type d -name $module`"
if [ -z "$origdir" ]; then
echo "Specified module does not exist"
return 1
fi
# Prepare to build
newdir="/var/abs/local/$module-$kernel"
if [ -d "$newdir" ]; then
rm -rf "$newdir"
fi
cp -R $origdir $newdir
cd $newdir
source PKGBUILD
if [ -z "$_kernver" ]; then
echo "PKGBUILD does not have $_kernver."
return 1
fi
sed "s/$_kernver/$kernel/g" -i PKGBUILD
sed "s/pkgname=$pkgname/pkgname=$pkgname-$kernel/g" -i PKGBUILD
# Build!
makepkg
# Post build messages/install
if [ $? = 0 ]; then
package="`find $newdir -name *pkg.tar.gz`"
# variable is at top
if [ "$pacman" = "1" ]; then
pacman -U $package
else
echo "Package is ready to install: $package"
fi
else
echo "Build failed"
fi
sorry if there's any stupid bash in there, i'm tired. and yeah, I know it's a tad verbose and spacy, but it seems to works fine.

[Solved]catalyst-rt module for realtime kernel

Hello,
I've compiled and intstalled the rtkernel with the directions posted here: http://bbs.archlinux.org/viewtopic.php?id=52201
My laptop uses an ati card and needs catalyst drivers. The fglrx module works fine with the vanilla kernel and pacman does not install it for the rt kernel(I think they are not compatible?) so I think I need the catalyst-rt module(also while installing the kernel, the pkgbuild told me that I needed catalyst-rt).
I could find no packages named catalyst-rt in the repos, but AUR database has one:
http://aur.archlinux.org/packages.php?ID=16825
But I think there is a problem with the install. After I compile the package and run it with "pacman -U", it complains about an unexpected EOF because of an unmatched quote mark. I've extracted the generated "catalyst-rt-8.5-2-i686.pkg.tar.gz" file to see if I can come up with something, there is indeed a missing quote in one of the echo statements in the contained catalyst-rt.install file. I tried fixing and retarring it but pacman complained about missing metadatas in the package. This is my 3rd day with arch(and one of those days my Internet connection was broken) so I don't have many clues.
I figure that there are very few people running ati drivers on a rt kernel here(searching for catalyst-rt yields to nothing) but maybe you can help me fix the issue myself, or maybe there is an easier way to use catalyst with an rt kernel?
Any help will be greatly appreciated. Thanks!

Ok, some more progress:
As I said, the vanilla kernel works fine with the catalyst drivers. Fully accelerated etc. When working with vanilla kernel if I say " dmesg | grep fglrx", the output is fine:
fglrx: module license 'Proprietary. (C) 2002 - ATI Technologies, Starnberg, GERMANY' taints kernel.
[fglrx] vendor: 1002 device: 71c5 count: 1
[fglrx] Maximum main memory to use for locked dma buffers: 1898 MBytes.
[fglrx] PAT is enabled successfully!

[fglrx] Reserved FB block: Unshared offset:ffbf000, size:40000
[fglrx] Reserved FB block: Unshared offset:ffff000, size:1000
As you can see, the loaded version is fglrx 8.50.3 [Jun 2 2008].
Now if I try the same on rt-kernel with catalyst-rt drivers loaded, the loaded version is shown as the incompatible fglrx 8.49.7 [May 12 2008] version.
The package PKGBUILD downloads is ati-driver-installer-8-5-x86.x86_64
So I assume that should be at least 8.5? Where does this loaded 8.49.7 come from?
I'm checking /lib/modules/<myrtkernel>/ to see if there are any other fglrx.ko floating around but there is only one, the one installed from the package built with ati-driver-installer-8-5-x86.x86_64.run
Since I'm not very competent with linux, I'm hoping some of you can show me some directions. I may try packaging a new ati driver to check but if ati-driver-installer-8-5-x86.x86_64 is actually 8.49, which one should I try then? 8-6? 8-7? I quite don't understand.

You can also try rebuilding the initrd image as jni suggested.

Is it possible to compile NVIDIA for multiple kernels simultaneously?

Hi all,
First, the reference is http://wiki.archlinux.org/index.php/NVI … tom_kernel, as well as a small discussion I started at http://aur.archlinux.org/packages.php?ID=20410.
Basically, currently the nvidia-beta (and I'm sure the rest of the nvidia scripts) use `uname -r` to obtain the current kernel name, which is then used for the rest of the PKGBUILD. Its relatively trivial to alter that to the name of whichever kernel, meaning there's no problem compiling nvidia.ko for kernel26-ice from within kernel26 itself, and to alter the name of the package so that your nvidia-beta package does not need to be over-written (you then have two nvidia.ko, each for their own kernel.
My question is, is it possible for a single PKGBUILD to compile nvidia.ko for all kernels currently installed (probably through looking at either /lib/modules or /usr/src)? This would mean only one maintainer is needed for nvidia-beta or nvidia-17xx or whichever series, and the same PKGBUILD could be used on any system, even those with multiple kernels.
I'm not very familiar with the limitations of PKGBUILDs, or the rules governing what they may or may not do (for example, accessing and checking the machine itself outside the fakeroot?), so this may be nonsense, if so feel free to point it out. Another idea would be for a simple bash script to create as many PKGBUILDs as required, based on the most recent nvidia-beta PKGBUILD, simply sed-replacing uname -r with the appropriate kernel names and modifying the PKG name.

Hi,
it's not difficult to do but I DO NOT recommend to do it (see my notes below the code).

PS: I haven't test it because I don't use multiple kernels
But be aware of possible problems. Some modifications may influence kernel functionalities, so once you compile a driver for kernel26-xyz on kernel26-zyx the module may not work on kernel26-xyz or may cause unexpected issues.
You also should not (you possibly even won't be able to) build module for different release version (eg. build for 2.6.28 on 2.6.29) due changes in kernel headers.
I'm also not sure if it is safe to generate module dependencies for another kernel then you are currently running.
As you can see above, it is not problem to make such a PKGBUILD, but it also brings too many problems and it's too dangerous that it is better to stay at current model "module package for each kernel". So if you want to you may try to use this PKGBUILD, but I strictly warn everyone else that it may cause more harm then use so don't blame me if something goes wrong. You were warned .

Oracle firewire modules for Redhat Linux 2.6.9-34.EL

Hi,
I need oracle firewire modules for Redhat Linux 2.6.9-34.EL. Can you please help where can I find firewire modules for this kernel.
Thanks
Haranath

According to http://www.linux1394.org/download.php you should not need any additional kernel module support. You may need to install the libraw1394 RPM packages, but you can get those from your distribution media or from ULN, if your are subscribed.

How to programmatically resize vi for different screen resolutions ?

Hi,
I have been struggling with this,How can i built a vi that should run for different screen resolutions (on different pc's).
There are several threads on forum , But i dont find the exact solution for it.
I have already tried with VI properties in the VI but i dont think its working.
Can someone please help me ?
Thanks and regards,
Shivkant Paswan

Yup it is a pain to use panes, but that is the easiest method I've found which meets my requirements. Learn to use panes and splitters effectively, and then learn their limitations and workaround when you find those limitations. In general LabVIEW should handle multi-resolutions, and resizing better but these are the tools we have today.

Virtualbox doesn't compiles "vboxdrv" module for 2.6.24 kernel

I installed Virtualbox, however I cannot launch any OS because the vboxdrv module doesn't exists for the latest kernel (I found another module for the 2.6.23 kernel); so the GUI says that I should execute this:
/etc/init.d/vboxdrv setup
However that file doesn't exists. I already tried to uninstall virtualbox and reinstalling from pacman, but still no luck.
What should I do? Is this a bug?
Thanks in advance.

I think that's where the confusion is. When I got the package from AUR it had:
-rw-r--r-- 1 ralvez users 217 2008-01-08 15:58 interfaces
-rw-r--r-- 1 ralvez users 3596 2008-01-20 11:38 PKGBUILD
-rwx------ 1 ralvez users 174 2007-12-30 04:23 vbox_build_module
-rw-r--r-- 1 ralvez users 2384 2007-12-30 07:39 vbox.install
-rw-r--r-- 1 ralvez users 2179 2007-12-30 07:31 vboxnet.patch
So the patch file is there (in bold text) ... and is not executable is a text file. That's why I'm asking if I have to do something with it to make the whole thing work.
Since it is just a plain text file if I try to use it as an upgrade patch it fails with error:
loading package data... error: error while reading package vboxnet.patch: Unrecognized archive format: Invalid or incomplete multibyte or wide character
error: failed to add target 'vboxnet.patch'
So, I'm stuck. I see no way to solve the problem.
R.
Edit: On re-reading your post I wonder what package from core are you referring to? I was under the impression that when we use AUR we are "fetching" files not from core but form the AUR source.
Am I wrong?

Compiling STREAM module for 64-bit kernel

Hi,
I am trying to compile a STREAM module for Solaris. The results I get when I execute "isalist" and "isainfo -kv" are:
-"sparcv9+vis sparcv9 sparcv8plus+vis sparcv8plus sparcv8 sparcv8-fsmuld sparcv7 sparc"
-"64-bit sparcv9 kernel modules"
The host is a Ultra5_10 with SunOS 5.7 sun4u sparc.
First I tried to compile the module with gcc 2.8.1 but altough the compilation apparentelly finisihed OK I did not get to load the module. Later I read that, gcc so far does not generate binaries for 64-bit sparc.
So I installed the Sun WorkShop 5 environment (try version) and I tried to compile my sources with the following line:"cc -D_KERNEL -xarch=v9 -xcode=abs32 -xregs=no%appl -x03 -I. -I/usr/include -c mymodule.c"
but I get a huge list of errors such as:
"/usr/include/sys/thread.h/, line73:warning: volatile is a keyworkd in
ANSI C"
"/usr/include/sys/thread.h/, line 73:sintax error before or at:volatile"
so if I compile adding the directire "-D_ASM" to the previous line, the list of errors descreases to 2 lines:
"/usr/include/sys/kstat.h, line 52: sintax error before or at: hrtime_t"
"/usr/include/sys/kstat.h, line 52: cannot recover from previous errors".
I have also tried adding directives such as: -D_LP64 -D__sparcv9 -D_POSIX_C_SOURCE, -D_XOPEN_SOURCE but I do not get to compile it successfully.
Could someone be so kind to give me a clue of what I am doing wrong, and what should I do in order to compile it??.
The header files I have included right now in my ".c" are:
#include <sys/stream.h>
#include <sys/conf.h>
#include <sys/modctl.h>
#include <sys/kmem.h>
#include <sys/cmn_err.h>
#include <sys/ddi.h>
#include <sys/sunddi.h>
If I do not add the directives -I. -I/usr/include to the compile line above I get the following error:
"/usr/include/sys/modctl.h, line 185: major, argument mismatch"
"/usr/include/sys/cred.h, line 51: sintax error before or at: uint_t"
But this is because the environment it is taken the /usr/ucbinclude as default include path instead of the "/usr/include". �which one should I consider?.
Thank in advance for your support.
Looking forward to hearing from you.
(could you please send to me the answeres to this e-mail:[email protected]??)
Regards
Elena

HI,
Maybe a file I can edit that says to run the Garmin stuff in 32-bit mode?
Right or control click the Garmin application (or utility) then click: Get Info
In the Get Info window under the General tab, if it can be enabled you should see:
Open in 32-bit mode.
Activity Monitor (Applications/Utilities) shows all apps running in 64 bit. If it doesn't have 64 bit under Kind on the right, then it's running in 32 bit mode.

Proper method for building kernel modules? [solved]

I am attempting to build a custom kernel module for a PCI express interface to an FPGA. However, I seem to be running into some issues with getting the standard kernel module makefile to work correctly. Here is my makefile:
# object files to build
obj-m += nnic.o
nic-objs += nnic_driver.o
all:
make -C /lib/modules/$(shell uname -r)/build M=$(pwd) modules
clean:
make -C /lib/modules/$(shell uname -r)/build M=$(pwd) clean
However, the first time I ran 'make', I got this output:

I have the linux-headers package installed. I do not need to build the whole kernel, only this small module. What am I missing here? What is the correct procedure for this?

Sigh, found the problem. Should be $(PWD) and not $(pwd) in my makefile.

   To verify that your adapter is supported, find the board ID number
   on the adapter. Look for a label that has a barcode and a number
   in the format 123456-001 (six digits hyphen three digits). Match
   this to the list of numbers above.
   For more information on how to identify your adapter, go to the
   Adapter & Driver ID Guide at:
   http://support.intel.com/support/networ … /21397.htm
   For the latest Intel PRO/100 network driver for Linux, see:
   http://appsr.intel.com/scripts-df/support_intel.asp
   More specific information on configuring the driver is in
   <file:Documentation/networking/e100.txt>.
   To compile this driver as a module, choose M here and read
   <file:Documentation/networking/net-modules.txt>. The module
   will be called e100.

Trouble building kernel module for sensor support

Hi, I'm new here but have been using Arch for a while. Recently, I decided to install Arch on an old laptop (Toshiba A70) and have managed to work out most of the kinks to where it runs nicely. Unfortunately, ACPI support is spotty and the /sys/class/thermal directory gives me only cooling_device0. I installed the lm-sensors package and ran sensors-detect, which yielded no results. Although the laptop runs smoothly otherwise, I would like to know the CPU's temp so that I would be able to set up a fan control scheme and CPU scaling (so far it's stuck at the lowest frequency, and that's kind of a big deal for me since the laptop runs on an archaic mobile P4 chip).
Sorry for the story but I felt some context was necessary. I did manage to find a kernel module that would connect those sensors to ACPI for me (http://sourceforge.net/projects/omnibook/), however I'm having trouble building it on the latest kernel. Here is the output from running make:
make -C /lib/modules/3.16.1-1-ARCH/build SUBDIRS=/root/omnibook-2.20070211 modules

Welcome to Arch Linux
That looks like it is a 2.6 kernel module

ASM module for kernel 2.4.21-27EL

Does anybody know from where I can download ASM module (RPM or source) for kernel 2.4.21-27EL . I managed to install ocfs module with that kernel using ENBD - project for network shared storage, but the ASM module for kernels 2.4.21x is compiled for 2.4.21-19
the source supports only 2.4.19...
Any idea anybody?

Hi, please send me the error log file,

User exit for different modules

Hi Everybody,
I want to search for all User Exits for different moldules.
Like for SD, MM.....how can we find that?
I know there is some way , Goto Se80, then.....
Please help me guys, its Urgent....
Will be rewarded.
Thanks in advance.
Regards,
Seevangi

Hi,
Go To Se84..
Give Program Name .
Display.
In the Tree U Will Have Option Called Enhancements
This Shows What R the Enhancements Available For That Program Or Transaction
User exits (Function module exits) are exits developed by SAP. The exit is implementerd as a call to a function module. The code for the function module is written by the developer. You are not writing the code directly in the function module, but in the include that is implemented in the function module.
The naming standard of function modules for functionmodule exits is:
EXIT_<program name><3 digit suffix>
The call to a functionmodule exit is implemented as:
CALL CUSTOMER.-FUNCTION <3 digit suffix>
To find a Exit.
Goto Transaction -- Find The Package
SMOD >f4>Use the Package here to Find the Exits In the Package.
Else if you Want to search by Application Area wise ,
There is one more tab to find the Exits in the Respective Application Area.
Implementing the Exit-- CMOD Create ProjectsAssgn your Component .
Now Run ur Transaction to Check if it Triggers.
Thats it..
Suppose you need to find out all the user exits related to a tcode.
1. Execute the Tcode.
2. Open the SAP program.
3. Get the Development Class.
4. Execute Tcode SE84.
5. Open the Node 'Envir. -> Exit Techniques -> 'Customer Exits -> Enhancements'
6. Enter the Development class and execute.
Check out this thread..
The specified item was not found.
1. Type the transaction : system->status-> <PROG. NAME>
2 open SE37 , type EXIT<PROG NAME> and press F4 to get the list of function exits available.
3. Open CMOD utilities->SAP enhancements
EDIT->All selections
4.type the function module name obtained in step 2, in fields 'component name' in 'additional selections' block. and execute.
5. The displayed list contains the enhancements names for the transaction You were looking for.
6. Create a project in CMOD and the code in default include->activate.
