Hi,
How does linux support more than 4G memory? I 've read the
documentation of Intel IA-32 Architecture, I knew that OS
just address up to 4G physical address space, If OS want to
access additional 4-GByte section of physical memory, it must
change the pointer in register CR3 or entries in the
page-directory-pointer table. That means that Linux just has
up to 4-GByte page mapping at one time , is that right?
