I have been looking for answer for this but never seem to get anywhere.
Supposed I have 16GB of physical memory, my question is, in 32bit x86
linux, how can I use the physical memory beyond the 4GB boundary in my
kernel drivers?
1. What CONFIG parameters for kernel compilation is needed (or is
for this purpose)?
CONFIG_HIGHMEM64G
2. Which are the main key functions or global variable for going
this? The pagetable is still the same mem_map right?
Didnt get your question , but mem_map is the array of all struct pages
in the system
, and not the page table.
