I have a problem in kernel 2.4.4
I use readw to access memory below 1MB , report "Segmentation fault"
and stall in memory
simple code below (this will get paraller port)
==
int init_module(void){
unsigned int *BIOS_Data=(unsigned int *)0x400;
u32 test;
test = readw(BIOS_Data);
printk(KERN_CRIT "0x400:%x\n",test);
}
==
but those can work in kernel 2.2.19 , no problem .
can anyone help me ?
