| Name | Describe |
|---|---|
| fpu__init_system | Called on the boot CPU once per system bootup, to set up the initial* FPU state that is later cloned into all processes: |
| cpu_init | pu_init() initializes state that is per-CPU. Some data is already* initialized (naturally) in the bootstrap process, such as the GDT* and IDT. We reload them nevertheless, this function acts as a* 'CPU state barrier', nothing should get across. |
