Hi,

Ok. But i dont try to write directly in physical address.

In code i put physical adress in mmap and it should give me virtual address that i can use to get access to registers.

Even the kernel can't use physical addresses directly. You must use those as 'kernel mode virtual addresses'.

And also i think to try to recompile linux, to be able to write drivers, e.t.c.

Is there an instruction how to compile linux with the same abilities (vga, usb, e.t.c.)?

Frankly speaking, I think that you don't have enough knowledge to make a driver yet.
