Hello, list
Could /dev/mem mean all physical memory when I make a hole in
ZONE_NORMAL. For example, if I create a memory hole by following code,
#define RAM_SIZE (256<<20)
zone_size[ZONE_DMA] = PFN_DOWN(16<<20);
zone_size[ZONE_NORMAL] = PFN_DOWN(RAM_SIZE) - zone_size[ZONE_DMA];
zholes_size[ZONE_NORMAL] = PFN_DOWN(RAM_SIZE) - PFN_DOWN(48<<20);
then I get a memory hole from 208M ~ 256M.
could I mmap() the reserved area into a process by
mmap(start, RAM_SIZE - 48, prot, flags, /dev/mem, 208M);
Best regards,
/Adam
