I am facing a problem while building a kernel module.
file1.c:
Quote:
#include <linux/kernel.h>
#include <linux/module.h>
#include "sam.h"
int __init sam_init(void)
{
printk(KERN_INFO "Hello, world - this is the kernel speaking\n");
return 0;
}
module_init(sam_init);

i am new to Ubuntu. i have been trying to port to linux but the region from which i come is still relatively new to computers and hence adheres to windows OSes. i have intermediate level knowledge of the c programming language. i have been trying to develop a driver for an USB device and i am stuck at making makefiles in maverick.
I am trying to write Ram Disk block device driver .
For that i am using add_disk() function . But system hangs while inserting the module .
I'm writing a Loadable Kernel Module for Linux that overwrites data in the memory address of another process. I want to overwrite a 4-byte integer.
Upon looking at ptrace(), I noticed a function named copy_from_user which, according to some documentation I found, seemed to fit the bill. However, when I try to load the module into the kernel (for a specific PID and address), it crashes.
I want to run my C code located in desktop with the header files located in other location. What should be the appropriate gcc command? I have attached the code below.
Just wanted to share some knowledge here.
The main code responsable for the random MAC wifi adress with the newer BCMDHD wifi driver is mainly due to a small peace of code :
eeprom-wifi-mac.c in /tf101-kernel_whatever/arch/arm/mach-tegra.
code snippet:
Code:
#include <linux/i2c/at24.h>
#include <linux/sysfs.h>
#include <linux/device.h>
#include <linux/slab.h>

Original source code :#include <stdlib.h>
#include <stdio.h>
#include <string.h>
int main(int argc, char** argv) {
int max = -1;
int mb = 0;
char* buffer;
if(argc > 1)
max = atoi(argv[1]);
while((buffer=malloc(1024*1024)) != NULL && mb != max) {
memset(buffer, 0, 1024*1024);
mb++;
printf("Allocated %d MB\n&quo
this code invoked Linux command by using C++ code, but how to convert it to use it as lib via NDK?
i see examples that use just .C files, and the variables used by Jni that different than C++ variable.
this c++ code that i need to convert it to use it then with NDK
#include <string>
#include <iostream>
#include <stdio.h>
std::string exec(char* cmd) {
FILE* pipe = popen(cmd, "r
I'm trying to understand timers in linux to use it in my application, I've collected code from multiple sources and made the following program
#include <stdlib.h>
#include <unistd.h>
#include <stdio.h>
#include <signal.h>
#include <time.h>
#include <pthread.h>
pthread_mutex_t mutex1 = PTHREAD_MUTEX_INITIALIZER;
#define CLOCKID CLOCK_REALTIME
#define SIG SIGUS
