Hi Guys, I have question on memory management in linux kernel. >From my understanding memory is divided into 3GB and 1GB for 32-bit architectures. 1GB is allocated to kernel space and 3GB is allocated to user space. To access any memory in kernel space, it should be mapped in to kernel virtual address space. My question is how do we know kernel address space (virtual address). Can we recognize a range of addresses, if so what is that range of kernel virtual address? What function returns kernel virtual address. Or do we need to map to get kernel virtual address. I know kmalloc returns logical address and vmalloc returns virtual address. And all these addresses should go through MMU to access physical memory. So there will be page mappings in kernel for these addresses. Is this true? Thanks in advance. -- Regards, Sri. -- To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
