GIET_VM / Boot-Loader
The GIET-VM boot-loader is defined in the 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()
