Is there a way for kernel to address larger than 1GB physical memory? I know
there is an option to split kernel/user space? Is this the only place I need
to change or there are other things need to consider? Do I need to recompile
any application running on top of this modified kernel? Share library
issues?
On i386 platform, where is the kernel space page table that use for MMU
mapping? How big is the actual kernel space?
Sorry for the bunch of questions.
