Hi,
I am writing a device driver in which I need to
allocate large amount of memory (say the size of the physical memory). I don't
care if the allocated memories are paged out (in fact I would like them to
be paged out, as I won't use them often), as long as they will be paged in at
the time I need to access them.
I understand vmalloc() would allocate up to the
size of the physical memory, but all the pages won't be swapped out, so I cannot
use vmalloc() for my driver, right?
Thanks,
Jason
