416 | Chapter15: Memory Mapping and DMA needed for the kernel code itself. As a result, x86-based Linux systems could work with a maximum of a little under 1 GB of physical memory. In response to commercial pressure to support more memory while not breaking 32- bit application and the system's compatibility, the
29 Mar 2015 Looking here, it seems the BIOS ROM appears at physical addresses 0x000F0000-0x000FFFFF. To get at that memory in protected mode with paging, you would have to map it into the virtual address space somewhere by setting up correct page table entries. Assuming 4 KB pages (the usual case),
Virtual memory map with 4 level page tables: 0000000000000000 - 00007fffffffffff (=47 bits) user space, different per mm hole caused by [47:63] sign extension Current X86-64 implementations support up to 46 bits of address space (64 TB), which is our current limit. This expands

27 Jan 2009 While the concepts are generic, examples are mostly from Linux and Windows on 32-bit x86. This first post describes how programs are laid out in In Linux, kernel space is constantly present and maps the same physical memory in all processes. Kernel code and data are always addressable, ready to

3 Nov 2014 After all the BIOS functions have been called, and your kernel is loaded into memory somewhere, the bootloader or kernel may exit Real Mode forever (often by going into 32bit Protected Mode). If the kernel never uses Real Mode again, then the first 0x500 bytes of memory in the PC may be reused and
26 Dec 2013 I don't know if you can peek the entire memory layout by just using the /proc filesystem. For a lab I designed for my students, I created a tiny device driver that allows a user to peek at an physical memory address, and get the contents of several control registers, such as CR3 (directory page base address).
1 Introduction; 2 Process Memory Layout; 3 Memory management Linux API In x86-64, only the least significant 48 bits of a virtual memory address would actually be used in address translation (page table lookup). Linux inherits its two basic system calls related to memory management from Unix: brk() and mmap().
