Function Documentation

void cpu_init ( void  )

cpu_init

This is our initial entry point for each CPU, and is invoked on the boot CPU prior to calling start_kernel(). For SMP, a combination of this and start_secondary() will bring up each processor to a ready state prior to hand forking the idle loop.

We do all of the basic processor init here, including setting up the caches, FPU, DSP, etc. By the time start_kernel() is hit (and subsequently platform_setup()) things like determining the CPU subtype and initial configuration will all be done.

Each processor family is still responsible for doing its own probing and cache configuration in cpu_probe().
