Kernel Memory related doubts!!!
Hi guys...
I have some basic questions related to kernel memory, * What is the difference between Kernel High Memory and Kernel Low Memory? *What is the difference between Kernel Logical Address and Kernel Virtual Address? Is it dat kernel logical address obtained from kmalloc() provides direct 1-1 mapping so one shud always prefer this option rather than vmalloc()call thier mapping is not always direct??? *Also, is there is anyway where we can specify some region of any IO memory mapped to kernel space as Cacheable and some as Non-Cacheable??? |
Are these homework questions?
