Hello ,

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)

note that first column is SIZE and second one is START

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.
