Re: Kernel/Userland Mem-Space Tuning (1/3 on IA32)

Hello. I read about address space division of recent operating systems like Linux and Windows XP. In both cases, the whole address space of the 32 or 64 Bit system is divided into halfes, 2GB for kernel, 2 GB for process(es) (speaking in 32Bit words). The same in 64bit systems like

sure about the exakt syntax but I know someone can change the half by half parity towards 1 to 3 in XP). I'm not sure whether FreeBSD divides kernel/userland address space this way, I know Linux and Windows does and on Windows we changed this (not yet on Linux and not yet on our FreeBSD
