Dear all, I was reading the LDD3's DMA chapter (chapter 15). The author talks about the splitting of address space between 1GB and 3GB. I couldn't make myself crystal clear as to why it is done. I got even more confused when he said kernel can't access physicalmemory address which is not mapped into kernel space. Why doesn't kernel has full access to all the address space?
