= GIET_VM / Boot-Loader =

The GIET-VM boot-loader is defined in the [source:soft/giet_vm/giet_boot/boot.c boot.c] file.

The ''boot_init'' function makes the initialisation in two steps:
 
The first step is sequencially executed by proc[0][0][0], while other processors are in wait state:
 * Physical memory allocators initialisation : ''boot_pmem_init()''
 * Page table initialisation : ''boot_ptabs_init()''
 * Proc[0][0][0] MMU activation
 * Private vobjs initialisation : ''boot_vobjs_init()''
 * Schedulers initialisation : ''boot_schedulers init()''
 * Peripherals initialisation : ''boot_peripherals_init()''
 * Kernel & application code loading : ''boot_elf_load()''
 * Start all other processors
The second step is executed in parallel by all processors:
 * CP0_SCHED register initialisation
 * MMU Activation 
 * Status Register Initialisation (to use the GIET_VM exception handler).
 * Jump to ''kernel_init()''
