hi all,
For a 32-bit machine, there is total 4GB of memory(Physiacl addresses). So in that 1 GB for Kernel and 3GB for User Space.
So, kernel won't access that 3GB of memory, right?
All the kernel code is exist in 1 GB of memory.... CMIIW
So, my doubt is the DMA(0-16MB),NORMAL(16-896MB),HIGH(896MB-) memory divided within this 4GB of memory ,right?
if we allocate the pages using alloc_pages, from which region the pages are allocated for the kernel modules. is it from Physical RAM memory or from 1GB of kernel space ??
