CPU information structure

alltime · 10-30-2005, 10:40 AM

I'm creating a number of Kernel modules to display specific information about the system but i'm not sure what header files/structures to use.

I want to use a strcuture that would list the following information

1) MAC address
2) Memory information (current memory, page file size, Hard drive space)

Okay I figured out the MAC Address. I just used linux/pci.h for gathering all of the information with use of inb in my function.

To get the MAC address in a more portable way (with PCI or NOT), you should

Code:

Open a socket
Prepare a ifreq structure with the name of the interface (eg eth0)
Pass the socket and the structure to ioctl , asking for ioctl SIOCGIFADDR
Then the MAC address is in ifreq.ifr_hwaddr, you can strcpy to your string
