Hi, I'm trying to read & display the GDT contents in kernel space. Is this permissible? I used the "sgdt" assembly instruction to load the GDT register, and found out the address & length of GDT from that (It is "0000c248") . Is this the physical or the virtual address? I'm now trying to print out the contents of GDT. I am able to print this address. BUt the moment I try to deference it, the kernel OOPS. I understand that this is because the address is not in kernel virtual address space (3GB). I tried using "ioremap" but it always returns NULL. Any ideas?
