Kernel Utilities

The utils.c​ and util.h​ files define useful kernel functions, that are used both by the boot_loader and by the kernel. They are prefixed by _ to remind that they can only be executed by a processor in kernel mode.

• They are used by the boot-loader in the static phase, to build the page tables and initialize the schedulers and the peripherals.
• They are also used by the kernel in the dynamic phase, to handle events such as interrupts, exceptions and syscalls.

CP0 and CP2 registers access functions

These functions can be used to access the MIPS32 protected registers

Physical addressing functions
