Hi

i am trying to implement a system call in linux kernel-2.6.29 but this file was missing /usr/src/linux/include/asm-i386/unistd.h

any idea
plz

Folks,

I have 5 machines getting the following errors:

here's what mcelog spat out

MCE 0

Hi,
I compiled kernel 2.6.29 for ixp425 processor. When I load thy zImage and run on my board (which is an E2Brain module with ixp425 processor, called EB425, manufactured by Kontron), it says

Starting user's image 0 ...

Hello,
I'm writing a char device module which should implement a cyclic buffer (with forced overwriting of older data). I want another module (a network device) to write on such cdev, while on the other hand I'd like to access the cdev with read operations from userspace.
On the network device I'm using sys_write (declared as extern) function,which seems the right function to do the job.

I am preparing a server for data acquisition from a big CCD camera. It uses PCI controllers which came with some software including a kernel driver module for 32-bit systems. Specs say Fedora 8 (2.6.26 kernel) but I found it working also in Centos 5.3 (2.6.18 PAE kernel). The driver requires that the appropriate amount of RAM is reserved for its use and it seems that it MUST be under 4GB.

Anyone got kgdb successfully patched on kernel 2.6.25.7 for ARM (arm-iwmmxt-linux-gnueabi)?

I get the following using 'linux-2.6.15.5-kgdb-2.4.tar.bz2' (couldn't find the exact kernel / patch?):

Hello all!
Does anybody know how to detect that MMC card is locked (by write-protection switch)? For example by ioctl or via sysfs?

P.S. I know that I could guess by write operations failure. :)

Hi Netdev,
Does the 82573E support jumbo frames,
I have about 130 Supermicro servers with this ethernet card, and im trying to slightly increase the mtu ie: babyjumbo.
I know that Intel does not support it, but comparing the FreeBsd em-6.9.8 driver to the linux e1000 shows that perhaps it is supported if ASPM is disabled.

if_em.c FreeBsd driver:

case e1000_82573:

I have to send a User defined signal {SIGUSR1 or SIGUSR2} to a process group.. possibly process group of the terminal. Can anyone help me? { i heard that send_sig_info or send_sig can be used. But i have no idea how to use it :(]

Hi all,
I am working on MPC8313erdb board, PowerPC, having linux-2.6.23.
I wrote simple hello_world module. At the time of compilation kernel generate error: "include/asm/current.h:35: error: invalid register name for ‘current’"

I can't understand the manning of this.

Code of hello_world module is given below

'm thinking on building a pc integrated into a keyboard, cheap yet strong enough to go online and run some kind of linux. it would preferably have a wireless internet port, a small hard drive (flash or cheaper) for the applications and OS, and the possibility to be plugged to a t.v. set or monitor lying around the house.

Hi folks,

i am successfully using gpio-keys on a custom AT91RM9200 board to react on On-Chip GPIO input events.
But if the system has just started, there is no way to figure out in which state these GPIO's are.
What i could do is enabling DEBUG_FS-Support and check /sys/kernel/debug/at91_gpio - but it seems a bit ugly to use a debug facility for production use.

I have a embedded ARM linux target and a linux host. I require to debug the embedded linux usbcore and usbserial.ko. I have built a debug kernel and debuf usbserial.

Now I have gdbserver on the target and gdb on the host. Using tcp how to I configure both the host and target to debug the usbcore?

Hi,

I am learning linux kernel. I have written a simple program to understand the usage of mutex variable.

Ideally the following program should generate race condition and should produce the different values on i,j,k and l rather than i = j = k = l = 100(LOOPCONSTANT * Number of threads) on usage of mutex. Here shared variables between threads are i,j,k and l.

hi folks, i'm trying to hook a function of the VFS, in order to hide a file in the filesystem
(actually a directory, containing some sensitive stuff)
i've read some papers that i found on google, even rootkit sources such as adore-ng
however they seem not to work under recent kernels

here is what i'm trying to do:

struct file *f;
