Hi... > can we figure out this 3G:1G split from process's address map below? More or less, yes. Check the highest address of stack (that means, the beginning of the stack in x86 since it grows downward). You'll see it reaches 0xC0000 0000 or 3GB. This is the user space part. Thus kernel space = 4-3=1GB. There you go, 3:1. > is the mem_init(which gets called from start_kernel) and which has the > arch specific implementation does the split? I can't really help you locating where exactly which kernel function that did this, but IIRC recent kernel does this by making PAGE_OFFSET selectable during kernel config. Thus grepping through Kconfig and kernel headers should bring you the clue. regards, Mulyadi -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
