There is a module A which is compiled with the kernel. I wrote an external module B which exported a symbol using EXPORT_SYMBOL.The module A now needs to talk with that exported symbol (function call). For that i modified A so that it includes the function call from B. However i now get unidentified symbol errors during 'make' operation as symbols of B are not present during kernel compile and A now kind of depends on B.
One solution is that make B part of the kernel as well. However, it would mean that whenever now i try to compile a kernel with a different source, i have to modify the config files and everything to accommodate B.Hence i am seeking a solution which does not include modifying the kernel.
i installed firefox 4 and removed the old 3.X version. did a general update that my computer showed me was available then i noticed the first problem. firefox 4 would not launch when i clicked it, it would only launch when i clicked the gnome 3 applications button and then clicked and dragged the firefox logo to the desktop, then it opened. the second problem i am now having which at the moment is more bothersome is that after i closed the lid to my laptop and opened it up again after a while and logged back in and noticed that the ENTIRE gnome 3 environment was gone. no panel no menu nothing just the desktop and a few desktop icons. i tried the command "yum install gnome-shell" but it just sed that gnome 2.31.5-7 .fc14.i686 was already installed so it wasnt gonna do anything, then i tried the "gnome-shell --replace" command and it just said

I have a Samsung phone GT-B3210. For some time I was unable to find working Windows drivers for it. I eventually gave up looking. Then one time I was charging phone over its USB port and booted Ubuntu and was pleasantly surprised when I saw phone's μSD card reader on my desktop. I now need to switch to Gento and would like to be able to work with phone there too. Lsusb tells me it's detected as Bus 007 Device 006: ID 04e8:663f Samsung Electronics Co., Ltd SGH-E720/SGH-E840but lsmod wasn't very helpful. On the list of loaded modules, I wasn't able to find one which looks like it's related to the phone.
how to find the driver module name using MAJOR NUMBER. In general major number list is available in Documentation/devices.txt but if i want to find out the driver module name specific for a given MAJOR NUMBER, what can be done?
I'd like openSUSE to automatically load a kernel module (e.g. libsas) at boot time even no device requires it. In Ubuntu, you would add the module name to the file /etc/modules. Is this the correct place for openSUSE as well?
I wish to recompile serial_core module to make a change in the way ioctl works. I don't wish to rebuild the whole kernel package. Can someone point me to the proper method?? I know I will need to download the kernel headers etc. But I would like to avoid the unneeded compiles of things I don't need to recompile.
I update my last kernl to 2.6.38-rc7 but when I launch VirtualBox, on stdout.The vboxdrv kernel module is not loaded. Either there is no module available for the current kernel (2.6.38-rc7) or it failed to load. Please recompile the kernel module and install it by sudo /etc/init.d/vboxdrv setup.
Recently I was trying to look into vmware pvscsi modules for newly announced linux kernel 2.6.35-rc2. I compiled the kernel with option: make oldconfig where it asked me for various interactive options and all I did is Kept pressing the Enter ENTER key(Donno if that is the correct way to slect default ).The Kernel Compilation anyway went fine and I can see new kernel at grub screen, booted and it went fine.Now when I explored I found that nor the vmware_balloon and vmw_pvscsi modules are present which means I need to install these modules.I came to know that recently a new version of the vmware memory drivers being included through this page:
where you can see an entry like:
MODULE_AUTHOR("VMware, Inc."); MODULE_DESCRIPTION("VMware Memory Control (Balloon) Driver"); -MODULE_VERSION("18.104.22.168-K"); +MODULE_VERSION("22.214.171.124-k");
Doesn't it mean that the new kernel has new driver version inboxed?Also, I tried to install modules through modprobe and insmod(seems that this doesnt work) but couldnt do that.
I cannot find the Xorg configuration file on my newly installed Debian on my tablet-pc, so I followed this tutorial [URL] and ran the command "Xorg -configure", to which I got the following error messages:
(EE) Failed to load module "vmwgfx" (module does not exist, 0) (EE) vmware: Please ignore the above warnings about not being able to load module/driver vmwgfx (++) Using config file: "/root/xorg.conf.new" (==) Using system config directory "/usr/share/X11/xorg.conf.d"
I am trying to install a Sunix 4018T dual parallel port card on a pc with Mandriva Linux 2010.1: Dealer told me that linux has driver for this card already so I inserted it and turned on my pc. Unfortunately when I try to install my Okidata ML320, cups it's not showing any parallel ports. I try to update all the system with last patches and packages :I tested the card on a pc with windows xp, installed my printer and it works perfectly.
I'm trying to enable the rewrite module in apache, to enabled the module I followed the last entry in the fist page this thread:[URL]...When I restart the apache all works fine, so I supose it's enabled
Now I create .htaccess in my apache folder (/home/user/apache), and I write this:
Code: RewriteEngine On RewriteRule ^link([^/]*).html$ test.php?link=$1 [L] And I try to execute this: ./.htaccess, I have this mistakes: Code: ./.htaccess: 1: RewriteEngine: not found ./.htaccess: 2: Syntax error: "(" unexpected What are I doing wrong?

These errors occurred during execution:

Got this error when I tried hash checking, was downloading the file using rtorrent when there was a sudden powercut and my system shutdown abruptly, tried restarting the torrent and kept encountering problems while restarting.
I am trying to write a kernel module that will DMA my custom card. Right now when i plug the card into linux no valid PCI device shows up (meaning I probably have a error on my end, i know) however, If I halt the system at startup in the bootloader (uboot) I am able to directly access the card as I know in uboot the physical memory address that is mapped to my device. Is there a way I can access the card in a simliar fashion in linux?
I have a loadable module, simple enough I believe it should run on any 2.6 kernel. I want to force the load and test that assumption. How can I do it?
ismod does not seem to notice the -f in 2.7 modprobe has -f but cannot locate the module.No go. So I read the manpage for modprobe which says: modprobe looks in the module directory /lib/modules/'uname -r'.So I copied MYMODULE.ko to /lib/modules/2.6.(the only directory in here) and type: modprobe -f MYMODULE.ko.Still can't locate MYMODULE.ko.I notice there are no other .ko modules in that directory; so I go in deeper to kernel/drivers/char, guessing about the char directory, and copy MYMODULE.ko there.
I am using FC9, I want to write a module that will always show current time after booting.But for that I need not only to load module using insmod/modprobe, but also to compile that module during boot time.How can I perform this 2 steps correctly.
i have written some really basic loadable kernel modules. There are a couple of concepts that i'll like to get cleared.
In a tutorial, the Makefile was given as follows- obj-m += try.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
I understand that -C option of 'make' changes the current directory to /lib/modules/$(shell uname -r)/build (which depends on my kernel).
Now, my question is why to change to that particular directory? Also M=$(PWD) will hold the dir where i have written the module. Why is it required? What does 'modules' at the end of that line indicate?
Q2> We need to include <linux/module.h> and <linux/kernel.h> in a module. If i am right, the module uses kernel headers for these definitions. But how does 'make' find these definitions.
Q3> We are planning to write a custom scheduler for linux kernel. cat /sys/block/sda/queue/scheduler gives us the currently loaded schedulers. How do we expose our scheduler to linux kernel so that we can use it by switching to it.
