I am trying to find out more information on large memory support (> 4 GB)
for Linux IA32. Is there a document that elaborates on what is supported
and what isn't and how this scheme actually works in the kernel?
My primary concern is whether a process can allocate more than 4 GB of
memory, rather than just be able to use more than 4 GB of physical
memory in the system.
Also, I see that the highmem support is just an option in the kernel.
Does this mean that there is a significant performance penalty in using
Any pointers/answers would be appreciated.
