Dear all: I write a driver for some pci device and the iomemory is requested by ioremap_nocache. The code is like below: kernel_memory = ioremap_nocache (start, len); My question is "Could I read and write the kernel_memory from console?" Is there buildin commands for me to use? Should I write a program to implement this? Since the memory is located at kernel. If the answer is the second one, could some tell me where can I find some sample code to modify or give me the basic system call functions I need to know. appreciate your help, vichy -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
