Message-ID: <200905251736.07951.shashank.bhatia@domain.hid> (raw)

Dear All,

I was trying to make a simple kernel module, and was unable to insert it into 
the kernel space. The code and Error messages are provided hereunder:


Code:
#include <native/task.h>
#include <native/timer.h>
#include <native/intr.h>

#define STACK_SIZE         0 

RT_INTR isrDesc;


int isrKbdHandler(struct xnintr* _idesc) {


  printk("module: catch a key\n");

  return RT_INTR_PROPAGATE; 

}



int init_module (void) {

  printk("module: Init\n");
  rt_intr_create(&isrDesc, "kbdisr", (unsigned)1, &isrKbdHandler, NULL, 0);
  rt_intr_enable(&isrDesc);


  return 0;
}



void cleanup_module (void) {

 
  rt_intr_delete(&isrDesc);
  
  printk("module: exit\n");
}

MODULE_LICENSE("GPL");




Makefile:


obj-m  = module.o


KDIR	= /lib/modules/$(shell uname -r)/build
PWD		= $(shell pwd)
EXTRA_CFLAGS = -I/usr/xenomai/include -I/usr/include/ 
default:
	$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules

clean:
	rm -f *.o *.ko *.mod.c *symvers *~



Error message:
