Hi,
I want to change the memory type of a particular memory region. I know
that the MTRR (Memory Type Range Register) is responsible of that in most
pentium processor-based systems. My question is to know if there is an API
in Linux to access this register (if yes, do you have example ) ?
Thanks,

Yes: /proc/mtrr. Read linux/Documentation/mtrr.txt
