[[PageOutline]]

The [source:soft/giet_vm/giet_common/utils.c utils.c] and [source:soft/giet_vm/giet_common/utils.h util.h] files define the functions used to access the CP2 registers (Memory Management Unit registers).

They are prefixed by  "_"  to remind that they can only be executed by a processor in kernel mode.

 === unsigned int _get_mmu_ptpr( void ) ===
Returns the value stored in the CP2_PTPR register, for the processor running the calling task.

 === unsigned int _get_mmu_mode( void ) ===
Returns the value stored in the CP2_MODE register, for the processor running the calling task.

 === void _set_mmu_ptpr( unsigned int value ) ===
Writes ''value'' in the CP2_PTPR register, for the processor running the calling task.

 === void _set_mmu_mode( unsigned int value ) ===
Writes ''value'' in the CP2_MODE register, for the processor running the calling task.
