Hello , during booting on MIPS IDT 79S334A i am getting following usable memory regions by print_memory_map in arch/mips/kernel/setup.c . memory: 8000fc00 @ 80000400 (usable) memory: 00e01d2b @ 001fe2db (usable) Initial ramdisk at: 0x8014c000 (604512 bytes) . . . above line i missed to mention in my previous post. note that first column is SIZE and second one is START address. my question is.. 1> what is the significance of usable memory , in terms of availibility for linux..? 2> where it is initialised ..i guess must be passed from firmware or from tags.. 3>on my board ram (16 MB)at 0x8000000 ,initial 0x400 is a room for exception table and hence effectively it would start from 0x80000400 . does this map relates to any way to LOAD ADRRESS ? i would like to add that i have problem of starting any user space process it is reporting always a bad memory acess on address 0x0fc01788.
