Re: If I don't active the page mechanism

Hi Mulyadi Santosa I think the OS can just use the segment mechanism to implement the virtual memory management. When I look through the intel manual find that the Segment Descriptor have a member P, when the P is set this segment is located in the physical memory otherwise the segment is not

Building linux headers in an non-linux environment

I'm trying to install linux headers for cygwin using crostool-ng. ct-ng basically invokes the line: make -C /home/richard/scratch/x86linux/.build/src/linux-3.5 O=/home/richard/scratch/x86linux/.build/i386-unknown-linux-gnu/build/build-kernel-headers ARCH=x86 INSTALL_HDR_PATH=/home/richard/x-t

Re: Fwd: Memory split in 64-bit environment

Every user process in the system has its own virtual address range that extends from 0 to TASK_SIZE. The area above (from TASK_SIZE to 2^32 or 2^64 ) is reserved exclusively for the kernel — and may not be accessed by user processes. TASK_SIZE is an architecture-specific constant that divides the a

Hi, I know very well that memory on 32-bit Linux system is normally split in following way First 3GB = user space (High memory) Last 1GB = kernel space (Low memory) But I have some questions, 1. How is memory split up on 64-bit architecture 2. Can we override this 3:1 split ? 3. If yes, who can
